En los próximos años los edificios se convertirán en productores y consumidores de energía al mismo tiempo. Por esta razón, la gestión de la demanda a nivel de edificio y a nivel de barrio a través de un agregador independiente requerirá de sistemas de control inteligentes con el objetivo de optimizar y gestionar dos aspectos: maximizar el uso de energía renovable local y usar la energía de la red en el momento más oportuno. El presente estudio se enfoca en los resultados de un sistema de algoritmos de optimización multi-nivel testeados en tiempo real. El experimento desarrollado reproduce, en dos laboratorios físicamente alejados 100 km, el comportamiento de dos edificios de un mismo barrio mediante un sistema semi-virtual donde unos modelos del edificio determinan su demanda energética emulandola en los laboratorios haciendo actuar al equipamiento físico en condiciones reales de trabajo. Los resultados muestran que la gestión inteligente de la masa térmica del edificio con los algoritmos de optimización puede aportar los mismos beneficios que instalar una batería eléctrica actuando con algoritmos inteligentes o de autoconsumo.

El presente trabajo tiene como objetivo analizar cómo se presenta mediante la guía docente la asignatura de Proyectos al alumnado del Grado en Ingeniería en Tecnologías Industriales (GRETI) en las diferentes universidades politécnicas españolas. Para realizar dicho análisis, se ha utilizado como instrumento de evaluación una rúbrica validada previamente por el grupo GRAPA (Grupo de Evaluación de la Práctica Académica de la UPC), y se ha aplicado a las guías docentes disponibles en las páginas web de las diferentes universidades de la asignatura de proyectos de GRETI. Los resultados muestran que a nivel global las guías docentes están muy bien elaboradas y obtienen una buena puntuación. Si observamos los resultados por ítems se observa que el que obtiene una puntuación más baja es el correspondiente a los instrumentos de evaluación mientras que los relativos a metodología y actividades son los que resultan mejor valorados. Los resultados sugieren que todavía falta por terminar de definir las competencias que desarrollarán a lo largo de la asignatura, los niveles de desarrollo y cómo se realizará la evaluación de las mismas, para verificar que el alumnado formado será competente en dichas habilidades

Nursing homes are set to be operated to meet certain thermal specifications defined by existing static principles. This article presents a case study of a nursing home to analyse the energy implications of the application of adaptive thermal comfort models for the elderly during the heating and cooling periods. The study included concurrent measurements of the outdoor and indoor environmental parameters and the collection of gas and electricity consumption during the monitoring period of the nursing home to elaborate a consumption model capable of predicting both the gas and electric energy consumption for a given meteorological condition. The research focused on a nursing home located in the Mediterranean city of Barcelona, which is a 3237 m2 building that has an all-water HVAC system with two different Air Handling Units. Applying the adaptive models into the consumption models resulted in obtaining potential savings in terms of energy, both for cooling and heating periods. The savings were higher as more extreme the outdoor conditions were. In general, the estimated potential energy savings were about 18.8% and 9.5% for cooling and heating, respectively. So, these results could be used to define good practices to design and operate nursing homes completely adapted to the environmental conditions in order to save energy demands without losing thermal comfort of the residents.

To achieve a feasible lifetime of several years, most satellites are deployed in orbits higher than 400 km. Drag of residual atmosphere causes a slow orbit decay, resulting in the deorbit of the spacecraft. However, e.g. optical instruments or communication devices would significantly benefit from lower altitudes in the range of 150-250 km. A solution to achieve this could be the application of atmosphere-breathing electric propulsion (ABEP), where the residual atmosphere is used to generate continuous thrust that compensates the drag. Within the EU-funded DISCOVERER project, the Institute of Space Systems (IRS) developed an electrode-less RF Helicon-based Plasma Thruster (IPT) suitable for such applications. Ignition and preliminary discharge characterizations of the IPT have been carried out at IRS facilities, using argon, nitrogen and oxygen. To further characterize the plasma plume, a torsional pendulum has been designed to determine the momentum flux in the plasma jet, as well as a three-axis magnetic B-dot probe to carry out time-varying magnetic field measurements. Various intake designs were investigated, opening the possibility to conduct studies on potential satellite platforms. A design study for an Earth Observation and Telecommunication satellite operating at 150-250 km with an extended mission lifetime is currently being carried out. The first system assessment focused on the comparison of different spacecraft configurations (“slender body” and “flat body”) and intake designs (specular or diffuse) with regard to overall drag and ABEP performance requirements. In this contribution, the proposed thruster characterization methods and the current status of the system assessment are presented. Upcoming experimental studies of the ABEP system and additional activities planned on system assessment are outlined.

Regular aerosol backscatter measurements using an elastic-backscatter lidar were performed between May 2000 and November 2002 in Barcelona (Spain), in the frame of EARLINET (European Aerosol Research Lidar Network). The mixing layer height, required to understand the chemical and physical processes taking place in the low troposphere, was one of the major parameters to be retrieved. Three analytic definitions of the ML height have been tested using the range squared-corrected lidar signal: (1) the minimum of its first derivative, (2) the minimum of its second derivative, and (3) the minimum of the first derivative of its logarithm. The strong coastal and orographic influences and the climatological settling of Barcelona determine the complexity of its atmospheric boundary layer dynamics and the high heterogeneity of the lidar signals. Therefore, single lidar analyses do not allow an unambiguous determination of the mixing layer height in many cases and complementary data are needed, such as synoptic maps, backtrajectories, radiosoundings and solar irradiance profiles. The resulting mixing layer heights were compared to radiosoundings, and the second method was found to give statistically the best results. This definition was used to process the whole dataset. A number of 162 days and 660 profiles were examined. The mixing layer height was inferred in cases such as low clouds, Saharan dust events and sea breeze and mountain induced recirculation. Variations between 300 and 1450 m were observed over the three years.

This study examines the necessity and contributes towards the development of a sustainable business model (SBM) for the emerging battery second use (B2U) market within the electric vehicle (EV) industry. Previous work identified that SBMs and EV B2U are emerging as major research streams but there is seems to be paucity among literature to deliver an overarching framework or a holistic view between these fields and highlight fresh areas for future research. We intend to unearth new knowledge through comprehending how B2U stakeholders undertake their business-related activities. These are not only focused on economic profitability but more importantly address wider social and environmental stakeholder value as part of prospective SBMs. We are using the SBM archetypes as the major lens for our data analysis to study multiple cases of B2U stakeholder roles and understand further the scope and ultimate purpose of their operations. Preliminary results indicate that the SBM archetypes lead towards sustainability innovation strategies that create a new conception of business models for sustainability in the EV B2U market. Additionally, although profitability is a major priority, it does not seem to be number one anymore. This is an element that confirms a new market perspective towards a sustainable circular economy. In turn, this creates shared sustainable value for multiple stakeholders through cross-sectoral collaborations. Ultimately, we aim to conceptualise a sustainable innovation business model (SIBM) framework for the B2U industry. The particular model includes such shared sustainable value creations which in turn drive forward business performance and sustainability at the same time.

This study shows the results of the SABINA H2020 project, which analyzes the effect of two level optimization algorithms to increase the consumption of renewable power sources and reduce greenhouse gas emissions. First, at building level, a building algorithm maximizes the self-consumption of generated energy by its own renewable power sources. Second, at district level, a market integrated district algorithm takes into account aspects related to the electricity grid, such as the electricity generation mix and the prices of electricity and ancillary services, and aggregates the energy flexibility forecast of buildings to minimize the overall CO 2 emissions while ensuring a cost reduction to prosumers

El objetivo de esta comunicación es el de describir el impacto ambiental que representan las instalaciones de iluminación. Toda actividad humana tiene un impacto ambiental sobre el medio ambiente, y para llevar a cabo esa actividad, se precisa luz. Cuando no se dispone de luz natural (o incluso cuando se dispone de ella), se genera luz artificial para seguir desarrollando dichas actividades humanas. Para proveer esa luz es necesario generar y consumir energía eléctrica, a la vez que fabricar, transportar, almacenar dispositivos que sean capaces de proporcionar esa iluminación. Todas esas actividades o procesos provocan impactos medioambientales, suponen consumo de recursos, emiten sustancias al medio ambiente y generan otras modificaciones ambientales durante su periodo vital. Para tratar de evaluar el impacto ambiental de un producto o un sistema es básico analizar el ciclo de vida del mismo. Así pues, en esta comunicación se tratará de describir el ciclo de vida de una luminaria, analizando todas las fases por las que pasa.

This paper presents the design and preliminary characterization of a novel 3D passive UHF-RFID tag. The prototype is fabricated using additive manufacturing techniques: 3D printing and copper electroplating. The design, manufacturing process and measurement set-up are presented and discussed in detail. We propose a biconical antenna design with helical strips in the cones to provide compactness without breaking the symmetry of the component and to improve bandwidth. The antenna is matched to a commercial UHF-RFID integrated circuit. The good agreement between results and simulations allows us to validate the whole process.

Spain is Pioneer in implementing Smart meters in Europe, having spread them in almost all territory. Presumably, this allows to increase the knowledge in the energy consumption of households, providing information to contract the most suitable power and tariff and to adjust consumption habits. Consequently, Smart meters are said to be useful to mitigate energy poverty. As a result of this presumption, Barcelona’s pilot site in the H2020 EmpowerMed Project developed a tool for diagnosis and energy audits that, from data collected through Smart meters, provides recommendations and knowledge for future decisions. The study presents the common difficulties found to get access to remote data from commercial smart meters, focusing on the particularities that affect vulnerable collectives. Moreover, the study characterizes and compares the energy consumption of energy poverty affected and nonaffected households to contrast the stereotypes this collective is subjected to and to put in evidence that their consumption is lesser and that they generally contract a power and tariff more suitable to their reality than those of non-affected households.

Este artículo parte de uno de los valores principales de la filosofía ‘Agile’ que se fundamenta en defender que las personas son lo más importante de una organización, dado que son quienes promueven su éxito o fracaso. El objetivo de este artículo es detallar la relación entre la orientación de una organización (tradicional/’Agile’) y la satisfacción de sus empleados, es decir, poder relacionar las necesidades, motivaciones, habilidades y cualidades de los empleados que conforman los equipos de trabajo con las políticas de la organización. Para ello se ha aplicado la metodología definida en el propio estudio (encuesta global y entrevistas individuales) en un departamento de una compañía del sector de la automoción. A pesar de que la muestra real de encuestados y entrevistados puede resultar en algunos aspectos sesgada e insuficiente, los resultados reflejan las debilidades y fortalezas de las políticas de gestión de equipos y empleados de dicha organización, así como los aspectos clave en los que debería actuar la organización para alcanzar ese óptimo de satisfacción del empleado que incremente la sostenibilidad de la organización.

La presente ponencia tiene como objetivo describir una metodología de cálculo basada en un análisis vectorial, que permite caracterizar y simular la Contaminación Lumínica emitida por una instalación de alumbrado exterior en un caso determinado. Para ello se realizó un planteamiento inicial, identificando los focos contaminantes en una población, y clasificando los casos de estudio teniendo en cuenta: las características geométricas del lugar analizado, las características fotométricas de las luminarias, las reflexiones del flujo en pavimentos, las reflexiones en paredes laterales y la presencia de arbolado viario. Posteriormente los datos recogidos se trataron informáticamente, y se realizaron simulaciones de los casos de estudio con la ayuda de un programa de cálculo lumínico. Los valores extraídos en el paso anterior se procesaron teniendo en cuenta la metodología vectorial propuesta, y se graficaron en una curva polar o fotometría global resultante. Los resultados obtenidos al desarrollar esta metodología permitieron cuantificar, modelizar y analizar la distribución espacial de la intensidad luminosa emitida en direcciones no útiles, causado por los diferentes tipos de instalaciones de alumbrado artificial en función de la estructura urbana analizada.

Este documento tiene como objetivo investigar la posibilidad de convertir materiales domésticos al final de su vida útil (EoLHM), como ropa o embalajes, en materiales aislantes térmicos y acústicos de bajo costo para la mejora del confort térmico y acústico en edificios, especialmente para hogares vulnerables en riesgo de padecer pobreza energética. Con este propósito, se presentará una revisión de la literatura y un análisis del comportamiento acústico y térmico de diferentes EoLHM con el objetivo de identificar una solución adecuada a instalar paredes verticales interiores garantizando una mejora de las condiciones acústicas y térmicas de la vivienda. ). Desde el punto de vista acústico, el mejor compromiso entre absorción acústica y pérdida de transmisión se ha obtenido para muestras hechas de cartón, pero también se han obtenido resultados interesantes para muestras hechas con dos hueveras, especialmente en términos de pérdida de transmisión. Asimismo, se ha demostrado que las prendas de ropa de mayor densidad aseguran un mejor rendimiento acústico. Desde el punto de vista térmico, la instalación de paneles de ropa y cartón determina respectivamente una reducción de la transmitancia térmica periódica y la transmitancia térmica. Sin embargo, debido a su mayor densidad, los paneles hechos de ropa son más efectivos. El resultado más importante de esta investigación es la comprensión de que la conversión de EoLHM en materiales aislante es posible, e implica una reducción directa de la producción de residuos, con claros y evidentes beneficios ambientales y positivas implicaciones sociales.

Social and economic trends have strongly changed in the last years due to the economic crisis and the evolution of technology. These factors have influenced a sharing revolution, also in the mobility sector motivated for the increasing urbanisation and environmental consciousness. The paper focuses on the intended use of shared mobility services by citizens of the metropolitan Barcelona region, relying on a quantitative analysis of their mobility patterns, behaviours, needs and expectations. Six hundred surveys with commuting travellers were conducted in order to identify the differences among customers regarding different factors, such as their age, daily trips or personal incomes. Results show clear different patterns depending on whether commuting trips are within or out of the city and a greater intended use of ridesharing, carsharing and ride-hailing services of the youngest population. Besides, data indicates that travellers do not have preferences for a single mean of transport but for the service that best meets their needs in each occasion.

An atmosphere-breathing electric propulsion system (ABEP) captures the residual atmosphere of a planet and uses it as propellant for an electric thruster to counteract the drag. The system would theoretically allow orbiting for unlimited time without on-board propellant storage. A new range of altitudes, e.g. 120-250 km in Earth orbit, the Very-Low Earth orbit (VLEO), for permanent orbiting can be accessed, thereby enabling new scientific missions. ABEP can be conceptually applied to any planet with atmosphere. IRS has several decades of heritage on the development of inductively heated plasma generators (IPG). Such devices are electrodeless, removing the issue of electrode erosion that reduces performance over time (see RIT, HET). Aggressive gases such as O as propellant, highly present in VLEO, will cause even faster erosion. IRS is currently developing an inductive plasma thruster (IPT) for ABEP application within the H2020 DISCOVERER project.

Despite their advantageous performance and reliability, distributed optical fiber sensors (DOFS) still constitute a recent technology and their reliability and accuracy when applied to real world structures is still under probation since there is still room for improvement and for widening their applicability. In general, standardized guidelines need to be developed to ensure success in every DOFSs deployment regarding fiber bonding to the structure, temperature affections on readings, postprocessing of reading anomalies, among other factors. However, real applications, as in the one presented in this paper, show that DOFS are anticipated to have a very important role in Structural Health Management of tunnels in the near future if correctly understood and developed. This paper addresses the implementation of a Distributed Optical Fiber Sensor system (DOFS) to the existing TMB L-9 metro tunnel in Barcelona for Structural Health Monitoring (SHM) purposes as the former could potentially be affected by the construction of a nearby residential building. The results show a good performance of this novel technique in the monitoring of strain along the whole affected sections during the construction of a nearby building. In fact, the DOFS readings reproduce very accurately the tunnel deformation process. The tendencies observed by the sensors were forecasted by a simple theoretical model. The monitoring of the strain at many points in the critical section allowed to conclude that the nearby construction only slightly affected the lining stresses and that safety was guaranteed during the whole monitored period.

This paper presents a new active gate drive for SiC MOSFETs switching. The proposed driver is based on feedforward control method. The switch is benefited from a simple and effective analog gate driver (GD). The main achievement of this GD is the transient enhancement with minimum undesirable effect on the switching efficiency. Also, the electromagnetic interference (EMI) as the main threat to the operation of SiC MOSFET is eliminated by this method. The proposed GD has been validated through the simulation and experimental tests. All the evaluation have been carried out in a hard switching condition with high-frequency switching.

Challenging space missions include those at very low orbits, where the atmosphere is source of significant drag on a satellite. Therefore, an efficient dragcompensation propulsion system is required to extend the mission lifetime. One solution is Atmosphere-Breathing Electric Propulsion (ABEP), a system that collects atmospheric particles and directly uses them as propellant for an electric thruster, therefore minimizing the requirement of limited propellant availability. The system is theoretically applicable to any celestial body with atmosphere. This would enable new mission types due to the new altitude ranges available for continuous orbiting. Challenging is also the presence of reactive chemical species, such as atomic oxygen in Earth orbit, erosion source of (not only) the propulsion system components, i.e. acceleration grids, electrodes and discharge channels of conventional EP systems such as RIT and HET. IRS is developing within the DISCOVERER project an intake and a thruster for an ABEP system. This paper, deals with the design of novel contact-less RF thruster, the inductive plasma thruster (IPT) based on a novel antenna design.

In this paper, an experiment where distributed optical fiber sensors (DOFS) were implemented in two small concrete beams subjected to a three-point load test is outlined. Here, an optical backscatter reflectometry based DOFS is implemented simultaneously embedded in the concrete (glued to the steel rebar) and attached to the outer surface of the concrete after its hardening. For comparison purposes, three electrical strain gauges are also used in the rebar. The main objectives with this experiment, is to analyze the feasibility of installation of DOFS directly on the rebar element of a reinforced concrete beam and compare the measured strain at rebar and surface of the concrete.

Sustainable recovery of critical metals from Waste Electrical and Electronic Equipment in the European Union requires information for detailed analysis, monitoring and decision making. Related knowledge is currently insufficient or disseminated through the network of stakeholders. This paper assesses the requirements of an adequate Database Management System with participation of different actors involved in the recovery of critical metals, and analyses the difficulties and the possibilities found for its implementation. The requirements of the Database Management System and the interaction of the different actors are presented, with the aim of supplying standardized information for management and research. Barriers are studied through a survey to identify obstacles for its elaboration. Limitations for its development are addressed and practical solutions for its elaboration are presented.

More than 65% of the total cost in buildings comes from Facility Maintenance Management (FFM). Despite that, facility managers have still relied on the traditional method. Building Information Modeling (BIM) based on Augment Reality (AR) can enhance the activity of FFM. In this study, a framework was developed for end-users and facility managers where the end-users report maintenance requests, while facility management (FM) department is responsible to manage them. This will help FM team to optimize building maintenance strategies and decision-making and finally reduce the costs associated with the maintenance activities in the buildings.

Formulating cost-effective and environmentally friendly energy retrofitting strategies for the existing building stock is a complex task due to the heterogeneity of this sector. The aim of this paper is to present an ongoing research project which is developing a model for assessing the suitability of energy efficient retrofitting measures and their corresponding economic and environmental performance in the existing stock of offices. The project draws upon the energy performance certificates database, including more than 13,000 office certificates issued in Catalonia since the entry into force of the Royal Decree 235/2013. First of all, a k-means clustering algorithm is used to identify office clusters and their centroids. Secondly, the closest energy performance certificate to each cluster centroid is selected from the database, prioritizing those simulated with the general procedure (HULC) but using those with the simplified procedure (CE3X) when needed. The energy performance of implementing several energy saving measures in each representative office is simulated using the general (or the simplified) energy performance procedures. Simultaneously, the corresponding economic and environmental performance are assessed taking into account the whole life cycle of the energy saving measure(s). Finally, an integrated model for assessing the energy efficiency improvement of the existing stock of office buildings is developed taking into account the energetic, the economic and the environmental impact. The project is expected to stimulate the existing energy retrofitting market, since the developed model can be useful during the decision making process for office owners or managers, public organizations aimed to promote the energy efficiency of the built environment, professionals related to building retrofitting or energy service companies.

Los recolectores de café se encuentran expuestos a diferentes condiciones ergonómicas que superan sus capacidades y limitaciones presentes en cada una de las actividades propias del proceso de recolección artesanal del café. El estudio evalúa esas condiciones por medio de observaciones y mediciones directas. Esta temática no se ha desarrollado previamente en Colombia. Sin embargo, diferentes estudios en cultivos de características similares en recolección artesanal como las manzanas o el café en otros países, demuestran la incomodidad y la necesidad de adelantar intervenciones en este campo para mejorar el nivel de salud de los trabajadores. Para ello, se incluyen mediciones directas (electromiografías de superficie) de trabajo en campo, tomando una muestra de recolectores en fincas cultivadoras del café del Departamento del Quindío. En términos generales, los valores máximos en todos los músculos superan el 20% de la máxima contracción voluntaria (MVC). Es importante señalar que en los participantes se observa alta variabilidad en el comportamiento del resto de los músculos, con la MVC del percentil 90 que alcanza el 10%. Por lo cual se determina necesario el desarrollo de una intervención en miras a reducir la carga sobre la espalda baja en los trabajadores de la recolección.

The authors conducted a laboratory experiment where two reinforced concrete beams were instrumented with a Distributed Optical Fiber Sensors that were adhered to allow the measuring of strain on four different longitudinal segments on their bottom surface. A fatigue test was then conducted on these elements where the load range was the one expected on a standard highway bridge between its permanent and the additional traffic load. Furthermore, each longitudinal segment of the DOFS was adhered to the concrete using a different adhesive in order to assess the optimal one in these fatigue conditions. The obtained data is then compared with strain gauges that were also instrumented on the concrete beams.

Building information modeling (BIM) widely adopted in design and construction phase of the buildings, holds undeveloped possibilities for supporting Facility Management (FM) tasks in Operation & Maintenance (O&M) phase. The purpose of this paper is to define appropriate Level of Development (LOD) for different FM areas in order to enable FM-BIM for existing buildings during O&M phase. To do so, the customized LOD have been defined by existing literature review and facility experts. Then the required properties for each FM areas are implemented in two case studies. Conclusion demonstrated that more than 60 percent of properties defined as LOD500 are unnecessary to execute FM tasks. Besides, the elements which required more properties are related to the categories of Services including Mechanical, Electrical and Plumbing (MEP) and fire systems and they need specific LOD to leverage BIM in O&M phase.

Aiming for synergies between indoor air quality in high-occupancy buildings and urban agriculture, this research investigates the capacity to enhance crop growth based on the generation of CO2 from occupants' exhalation in university classrooms. Accordingly, the CO2 concentrations of eight campuses classrooms of the Polytechnic University of Catalonia have been analyzed over a period of one year. The data have been obtained from sensors installed through the climate action strategy designed by the university and are available through SIRENA platform. Results show great potential in the utilization of exhaled CO2 thanks to the generation during school periods. However, the profiles obtained show discontinuous CO2 availability throughout the year and during the hours of maximum photosynthetic activity of plants. Moreover, the measured CO2 levels exceed, on many occasions, the recommended limit for crop growth.

Francis turbines are increasingly demanded to work at part load in order to satisfy the electricity generation demand and to compensate the non-constant generation of other renewable sources such as wind or solar. At part load, Francis turbines present complex flow patterns dominated by cavitation and especially by the draft tube vortex rope. The vortex rope phenomenon affects the structural behavior of the machine as well as the hydraulic circuit response and, for certain conditions, it could become unstable. At this situation, the output power can significantly swing endangering the electrical grid stability. This condition has to be well-known and avoided as far as possible. In this paper, the phenomenon of the power swing at part load in prototypes is studied. For this purpose, different Francis turbine prototypes have been selected. The units have different specific speeds and therefore different power, head and geometry. All of them present the power swing phenomenon at part load. Different sensors, such as accelerometers, proximity probes, pressure sensors or strain gauges, have been placed in different positions of all the machines in order to detect and quantify the phenomenon. The relationship between the hydraulic phenomenon and the output power swing is presented for all the turbines studied. Results obtained permit to asses on the on-site detection of power swing as well as the possibility to avoid it in real-time.

DISCOVERER is a new 5.7 million Euro, 4.25 year Horizon 2020 funded project which aims to radically redesign Earth observation satellites for sustained operation at significantly lower altitudes. The satellite based Earth Observation/remote sensing market is one of the success stories of the space industry having seen significant growth in size and applications in recent times. With global revenues from Earth imagery and data services set to exceed 4 billion Euro by 2024 up from 2 billion Euro in 2014, the market can be said to be booming. Yet key design parameters for the satellites which provide the data for this market have remained largely unchanged, most noticeably the orbit altitude. Operating satellites at lower altitudes allows them to be smaller, less massive and less expensive whilst achieving the same or even better resolution and data products than current platforms. However, at reduced orbital altitude the residual atmosphere produces drag which decreases the orbital lifetime, and aerodynamic perturbations challenge the ability of the platform to remain stable affecting image quality. DISCOVERER intends to overcome these challenges by carrying out foundational research in the aerodynamic characterisation of materials, in atmosphere-breathing electric propulsion for drag-compensation, and in active aerodynamic control methods. In order to put these foundational developments in context, DISCOVERER will also develop advanced commercial and economic models of Earth observation systems which include these newly identified technologies. This will allow the optimum satellite designs for return on investment to be identified. DISCOVERER will also develop roadmaps defining the on-going activities needed to commercialise these new technologies and make very low Earth orbit, Earth observation platforms a reality. The DISCOVERER project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 737183.

According to United Nations data, currently half of the world's population lives in cities. In Europe this figure is higher. Cities are transformed to improve the performance and quality of urban services. In technologically developed countries, cities are moving towards the Smart City system, based mainly on wireless technologies and information systems. In terms of sustainable development, Smart City technology is an area to explore and to define. It is necessary to quantify its impact in order to objectify it and to generate new fields of action. The objective of this work is to propose a methodology that allows identifying, evaluating and quantifying the environmental, economic and social impacts associated with a wireless sensor network, the main structure of the Smart Cities. It is developed in two phases: in the first one, the methodology for impact evaluation is developed and proposed. In the second one, this methodological proposal is applied to a real case and the results are discussed. It is concluded that advocating the establishment of technology in cities is the engine of change as long as the city is prepared to contribute in terms of management.

There is a growing need to optimize the heating ventilation and air conditioning (HVAC) systems during building operations due to its high contribution to buildings' energy consumption and the willingness to meet the international energy and climate changes targets. Predictive and adaptive controls have arisen as proper tools to reduce the HVAC's energy consumption. They can predict future scenarios and determine the optimal strategy to manage HVAC systems. In this regard, control strategies based on neural networks (NN) to manage boilers and control the temperature setbacks are attracting significant attention. This study aims to use the reduced-order building descriptions as a benchmark model for building energy simulation to demonstrate an NN-based control's effectiveness in managing boilers in buildings. Reduced-order buildings will be simulated with different meteorological locations from various climate zones to determine if the proposed control system is more efficient than a schedule-based control or if certain zones have more potential to save energy. To carry out this analysis, a set of KPIs will be used to assess the performance of the proposed control and compare the results within the different scenarios and the baseline scenario, the scheduled-based control.

The textile industry is a major contributor to water consumption and greenhouse gas emissions, ranking 4th and 5th respectively in terms of impact in the EU. The process of major concern are the finishing operations, such as brightening, dyeing, printing and mercerizing, which require water at high temperatures. These processes result in effluents with high levels of alkalinity and conductivity, making their wastewater ideal for electrochemical treatment. The industry has used various strategies to treat these wastewaters, but has not considered using electrochemical processes in conjunction with hydrogen co-generation, which could help decarbonize the textile finishing industry. The study evaluates the use of mercerizing and dyeing effluents as electrolytes for hydrogen production, coupled with color removal in the latter. The hydrogen flow rate depends solely on the effluent conductivity, with no detected effect from the present contaminants. Both effluents achieve hydrogen generation efficiencies of over 70%. The electrochemical treatment of dyeing effluent achieves 97-99% color removal and generates hydrogen equivalent to 19,5% of the electric energy consumed during treatment.

Existing field studies confirm that elderly people have different thermal sensation from adults. This paper presents the results of a study conducted to 1204 nursing homes’ residents from Sanitas Mayores, using a thermal sensation questionnaire and measurement of indoor climatic parameters. The aim of this study was to analyse the thermal comfort during the winter and summer periods of elderly people living in nursing homes and compare their thermal satisfaction in four different shared rooms: living room, dining room, occupation therapy room and gym. Longitudinal field measurements were conducted in five nursing homes in a Mediterranean climate during the winter, from January to March 2019 and the summer, from June to September 2019. Room air temperature (Ta), relative humidity (HR%), mean radiant temperature (Tr) and air velocity (va) were recorded using a Delta Ohm HD32.1 instrument with an anemometer, thermometer and a black globe thermometer. “Right-here-right-now” thermal responses of occupants were collected using a face-to-face questionnaire delivered intermittently. A total of 1204 questionnaires were collected and then matched against concurrent indoor and outdoor thermal conditions. The results indicate that residents of nursing homes in the Mediterranean climate had different thermal sensation depending on the room where they occupy. Therefore, clothing adaptation or ventilation strategies might help thermal adaptation to residents’ thermal needs. The modification of temperature setpoints in nursing homes rooms based on the results of this study could influence energy use and should be carefully considered by policy makers and nursing homes’ facility managers.

To extend missions lifetime at very low altitudes, an efficient propulsion system is requiredto compensate for aerodynamic drag. One solution is Atmosphere-Breathing Electric Propulsion (ABEP). It collects atmospheric particles to be used as propellant for an electric thruster. The system ideally nullifies the requirement of onboard propellant storage.An ABEP system can be applied to any celestial bodywith atmosphere(Mars, Venus, Titan, etc.), enabling new mission at low altitude ranges for longer times. Challenging is operation of the thruster on reactive chemical species, such as atomic oxygen, that is highly presentin low Earth orbit,as theycause erosion of (not only) propulsion system components, i.e. acceleration grids, electrodes, neutralizers, and discharge channels of conventional EP systems.For this reason, a contactless plasma thruster is developed:the RF helicon-based plasma thruster (IPT). The paper describes the thruster design, implementation, and first ignition tests. The thruster implements a novel antenna called the birdcage antenna that is implemented for decades in magnetic resonance imaging (MRI)machines. The design is supported by the simulation tool XFdtd®. The IPT is aided by an externally applied static magnetic field that provides the boundary condition for the helicon wave formation within the plasma discharge.The antenna working principle allows to minimize losses in the electric circuit and provides, together with the applied magnetic field, acceleration ofa quasi-neutral plasma plume.

Erosive cavitation in hydraulic turbines affects severely the runner structure, increasing maintenance costs and reducing the remaining useful life of the component. Actual vibro-acoustic techniques used to detect this kind of cavitation in hydraulic turbines are based on analysing high-frequency vibrations in different parts of the unit. Particularly, the demodulation of high frequency bands has proven to give relevant results regarding the erosive cavitation behaviour. However, demodulation is not absolutely conclusive since the excitation and the transfer function from the excitation to the measuring point, which depend on every particular prototype, are partially unknown. In this paper, the demodulation method to detect erosive cavitation in hydraulic turbines is reviewed and analysed in detail. To do so, first, an experimental study in a test rig in laboratory has been carried out. This test rig is based on a rotating disk instrumented with a piezoelectric patch and with different sensors, such as accelerometers and acoustic emission sensors, in the rotating and stationary parts. Different excitation patterns simulating erosive cavitation have been applied to the rotating disk. These patterns include pseudo-random excitations of different frequency bands modulated by one low carrier frequency, which model the erosive cavitation characteristics. In this way, it is possible to understand how mechanical vibrations similar to those produced by erosive cavitation are transmitted in such complex systems involving fluid and solid mediums. The knowledge obtained in the test rig helps to interpret the results obtained with demodulation analysis in prototypes. Particularly, in this paper these conclusions have been used to analyse erosive cavitation in a real Francis turbine.

Rapid global urbanisation in 21st century results in cities consuming vast resources but also offering unique opportunities for more integrated and circular resource management. This work investigates potential benefits of urban agriculture and buildings integration through a demonstrator building (ICTA). Actual building and integrated Rooftop Greenhouse (iRTG) data demonstrate wide thermal profiles across ICTA six levels and the potential for heat exchange within the building. Calibrated model monthly results indicate reduced building heating needs resulting from iRTG inclusion. However, more modest GSHP electrical cooling reductions resulting from plant transpiration
showed reversing potential which requires more in-depth analysis of underlying principles.

The demand for elderly care centres (ECCs) is increasing as the population ages. This paper presents a field investigation on the thermal comfort of elderly in ECC and compares the outputs of existing thermal comfort standards with perceived thermal comfort of the elderly occupants of the building. Indoor and outdoor conditions were measured along the year and in different zones of an ECC (bedrooms, living rooms and dining rooms). A questionnaire survey to the residents was used to gather the occupants’ thermal satisfaction. The findings indicate that standards based on adaptive models to evaluate the thermal comfort in elderly people are more precise than those based on the predicted mean vote (PMV). Results also highlight that this group prefers higher temperatures than the rest of the population. The findings also suggest that the time of the day and if the space is air conditioned do also influence thermal comfort in ECCs. These results can help standardise thermal comfort of elderly people.

To determine the air ventilation flows in a room deterministic approaches based on the CO2 tracer-gas mass balance equation are usually used. Those equations do not enable to introduce to the system uncertainties such as the sensor measurement error. In this paper, the use of the stochastic differential equations based on the CO2 tracer-gas mass balance are presented to obtain the air ventilation flows in a room introducing uncertainty elements. This kind of modeling, also known as grey-box modeling, combines physical knowledge of the system and information embedded in the monitored data to identify a suitable parametrization of the differential equation used. Finally, a set of statistical tests are used to assess the model's accuracy. Models that fulfill the tests are considered correct, and as a consequence, its parametrization too. Having the parametrization a physical meaning, it is possible to obtain the air ventilation flow of the room. Results show the viability of this kind of approach.

Las competencias “aprender a aprender” y “autonomía en el aprendizaje” son inherentes a la formación del ingeniero que trabaje en (o por) proyectos. El proyecto, entendido como proceso buscador y generador de soluciones, demanda que el proyectista adquiera constantemente nuevos conocimientos para aplicarlos acorde con las necesidades y características de los proyectos en los que participa. En consecuencia, los actores de la formación del proyectista están llamados a reflexionar sobre qué significan estas competencias y procurar contextos educativos para que el aprendiz pueda fomentarlas. Con el fin de aportar a estas reflexiones, se presenta un estudio y análisis de los elementos constitutivos de los constructos “aprender a aprender”, “autonomía en el aprendizaje” y “autorregulación del aprendizaje”. Estos constructos están relacionados estrechamente, en muchos casos son usados de manera indiferente y sin embargo tienen significados distintos. El resultado es una herramienta para diseñar actividades que busquen fomentar la autorregulación del aprendizaje. Se espera que esta comunicación brinde a los docentes y estudiantes interesados en las competencias “aprender a aprender” y “autonomía en el aprendizaje” elementos para enfrentar las confusiones teóricas que afectan la comprensión de estas competencias e insumos para el diseño de actividades que fomenten la autorregulación del aprendizaje.

The energy and transportation sectors are responsible of the higher part of the greenhouse gas emissions in EU and the world. If the climate change is to be fought, a change in the paradigm should be done.
The road transportation sector is shifting to an electrified mode. The electric vehicles are mostly powered by Li-ion batteries having an eight to ten years warranty, when they are expected to have an 80% of its
original capacity and are considered inappropriate for traction services.
On the other hand, energy storage devices are called to have an important role in the electricity market.
They can provide a wide range of environmental and practical benefits, such as the support to renewable electricity generation, the distributed generation and the energy management among others. But
nowadays, the Li-ion batteries are too expensive to provide such services with economic profit.
The particular case presented in this paper is a demonstrator project that connects both sectors by providing a second life to the electric vehicle batteries and offering low cost batteries to the energy sector.
Its four plug-in electric vehicle batteries are connected to solar panels, electric vehicle chargers and the electricity grid. The aim of this project is to verify that there are profitable and clean energy businesses for
these batteries.
An electric battery ageing model is presented in the paper. It has been developed in Matlab including the different ageing mechanisms, such as calendar ageing, C-rate, Depth-of-discharge and heat losses. This
model simulates the battery capacity fading for the different applications and determines its rest of useful
life.
The demonstrator will validate the model and it will enhance the re-use of batteries for grid and home
services before recycling, with the environmental profit and energy savings derived by its use.

A hyper-thermal orbital aerodynamics test facility is described. The Rarefied Orbital Aerodynamics Research facility(ROAR)is a dedicated apparatus designedto simulate the atmospheric flow in very low Earth orbits(VLEO) to investigate the impact different material properties have on gas-surface interactions, and determine the aerodynamic properties of materials from the reemitted gas distribution. The main characteristics observed in VLEO to be reproduced are the free molecular flow regime and the flux of oxygen atoms at orbital velocities impinging on the spacecraft surface. This is accomplished by combining an ultra-high vacuum system with a hyper-thermal oxygen atoms generator. Materials performance will be assessed via a scattering experiment in which an atomic oxygen beam is incident on the surface of a test sample and the scattered species are recorded by mass spectrometers. The design of theexperiment is discussed, from the specification of the vacuum components to the generation of oxygen atoms and their detection.

Flying at VLEO has several advantages such as the increase of the resolution of images recorded by optical instruments, the increase of geospatial position accuracy, the improvement of the signal to noise ratio and the reduction of energy consumption by active payloads. However, the drag produced by the interaction of the atmospheric gas particles with the surfaces of the spacecraft requires an extended knowledge of orbital aerodynamics. The aim of this work is to carry out a study from the principles of orbital aerodynamics to the definition of requirements for a set of satellite platforms covering Earth Observation applications taking advantage of operating in Very Low Earth Orbit (VLEO) and making use of aerodynamic technologies. Four platform concepts were defined: optical coverage platforms, optical Very High Resolution (VHR) for high performance platforms, low cost optical VHR platforms and Synthetic Aperture Radar (SAR) platforms. In addition, the main orbit and attitude control operations to be done with these concepts were analyzed. A relation between the different mission concepts and the performances to be obtained with enhanced aerodynamics was established to identify which of the four platform concepts could perform as a commercial platform to guarantee the use for different applications.

Es cada vez más evidente que el creciente consumo de combustibles fósiles a nivel mundial es actualmente el mayor responsable de la contaminación atmosférica en todo el planeta y, como consecuencia, de la alteración del clima por las emisiones de gases de efecto invernadero y del aumento de problemas respiratorios en la población. Uno de los sectores en los que ese consumo es importante y, además, tiene mayores tasas de crecimiento en los próximos años es el transporte, y en particular, el uso del vehículo con motor de combustión interna (VCI). Es por dicho motivo que recientemente varios países, entre ellos España, se están planteando prohibir la circulación de VCI en un futuro cercano (año 2040) y sustituirlos paulatinamente por vehículos de emisión cero, especialmente vehículos eléctricos (VE).
Para colaborar en reducir las emisiones contaminantes de VCI, algunas empresas están incentivando económicamente la reducción del uso de VCI de los trabajadores para desplazarse hacia/desde sus lugares de trabajo. Estas medidas tienen sin duda un triple impacto a nivel ambiental, socioeconómico, y también en la salud.
Este trabajo pretende analizar esas medidas y evaluar su impacto, estudiando los casos de tres tamaños de empresa: pequeña (<50 trabajadores), mediana (<250 trabajadores) y grande (>250 trabajadores).

The notable contribution of Machine learning in recent decades lies in the widespread use of artificial neural networks (ANN). These networks have become predominant for accurately predicting non-linear structural behaviours, revolutionizing engineering with enhanced safety and precise predictions. In earthquake engineering, ANN's application, especially in analyzing seismic structural responses, offers diverse possibilities. This paper analyses a database of 287 cyclic tests on concrete columns and demonstrates that ANNs are powerful tools for predicting hysteretic damping for the implementation in the Direct Displacement Based Seismic Design Method (DDBSD) during design phases. The study emphasizes the significance of ANN-driven approaches in seismic design methodologies, showcasing differences between simplified methods and experimental database predictions.

O uso de fibras em concretos tem ganho um maior espaço no meio da construção civil e a publicação do fib Model Code 2010 pode ser considerada um grande avanço nesse sentido. Indicando a possibilidade de uso estrutural do concreto reforçado com fibras (CRF), o novo código abre portas para ampliar o mercado do material. No Brasil, seu uso é dificultado pela ausência de qualidade de ensaios de controle, resultado da falta de um método de ensaio normatizado. Para isso, tem sido proposto o ensaio de duplo puncionamento (Ensaio Barcelona) AENOR UNE 83515 (2010), que quantifica a resistência residual do CRF. Porém, o ensaio segundo a norma é de difícil disseminação prática devido aos custos associados ao sistema de medição da deformação radial dos corpos de prova. Dessa forma, sua versão simplificada é promissora, substituindo a medição de expansão perimetral dos corpos de prova por deslocamento axial. O ensaio também pode apresentar grande instabilidade na região pós-fissuração da matriz e variabilidade de resultados na etapa residual. Para o presente estudo, a utilização de corpos de prova cúbicos com duplo entalhe lateral foi testada em termos de diminuição na dispersão da resposta. Os resultados demonstraram que o entalhe não é efetivo em termos de dispersão. A influência do entalhe se mostrou significativa para a redução da instabilidade, uma vez que cargas de pico menores geram resultados mais estáveis.

Pollen allergenicity plays an important role on human health and wellness. It is thus of large public interest to increase our knowledge of pollen grain behavior in the atmosphere (source, emission, processes involved during their transport, etc.) at fine temporal and spatial scales. First simulations with the Barcelona Supercomputing Center NMMB/BSC-CTM model of Platanus and Pinus dispersion in the atmosphere were performed during a 5-day pollination event observed in Barcelona, Spain, between 27 – 31 March, 2015. The simulations are compared to vertical profiles measured with the continuous Barcelona Micro Pulse Lidar system. First results show that the vertical distribution is well reproduced by the model in shape, but not in intensity, the model largely underestimating in the afternoon. Guidelines are proposed to improve the dispersion of airborne pollen by numerical prediction models.

Numerous research reported in the scientific literature show the feasibility of inerting sewage sludge in ceramic matrices as structural or red ceramic material for construction. However, its industrial implementation is hampered by a social rejection from the environmental movements.
Is this process an undercovered waste incineration or rather a pyrolysis process with reduced environmental impact? If there are countless incinerators, why does the manufacturing process of clay bricks with sewage sludge have legislative difficulties and generates numerous social conflicts?
This study analyzes the data of gaseous, particulate matter and odors emissions produced in the sintering of clay/sewage sludge ceramic pieces. According to laboratory tests, VOC emissions for the clay/sludge material were in general higher than those from conventional ceramics. However, no VOC exceeded the threshold limit values and only a few compounds showed concentrations that exceeded their odor detection threshold. Besides, three inorganic pollutants exceeded the maximum levels (NOx, suspended particles and HCl). In a test at industrial level, the most important emissions were those of CO (1100 mg/Nm3), TOC (1085 mg/Nm3) and HCl (71 mg/Nm3).
Finally, from this experience, the main guidelines to be followed by any implementation of industrial ceramic plants to be respectful with the environment rules are proposed.

Buildings are responsible for 40% of the energy consumption and around 36% of CO2 emissions in the European Union. Administrations are funding projects enhancing energy efficiency to achieve a zero-emission building. As a consequence, many companies perceive the business potential. Several public buildings are analyzed by comparing their energy rating labels against their real energy consumption. Results show that highly rated buildings are also the ones with higher consumption. This study analyzes and discusses the factors that end up in this paradox. Results show that new buildings consume more energy, which is caused by higher interior-comfort standards. Moreover, control systems that should warrant optimal functionality of the building consume non-negligible amounts of energy. Finally, technical exigencies on buildings have increased in recent years. In conclusion, project management should incorporate the structure, control, security, and comfort systems together in the design phase. Moreover, this phase should also include the operating definition of the building during the day and throughout seasons of the year.

La calidad del aire que se respira en las calles de Barcelona ha empeorado en los últimos años, siendo la contaminación atmosférica procedente del tráfico rodado, y más en concreto, de los vehículos de combustión interna (VCIs), una de las principales causas.
Por ello, el Ayuntamiento de Barcelona ha presentado un plan global para mejorar la calidad del aire de Barcelona, a través de una serie de medidas, muchas de ellas dirigidas a reducir el impacto del tráfico en la contaminación del aire de la ciudad.
En este trabajo se analiza la repercusión que puede tener en particular, la medida de incentivar la retirada de los vehículos más antiguos subvencionando, a cambio, el uso de servicios relacionados con modos de transporte más sostenibles, como abonos de transporte para el uso de bicicletas compartidas, transportes públicos, etc.
Según el escenario estudiado, la retirada paulatina de la circulación de todos los VCIs anteriores a Euro 5 en 2027, supondría una reducción de un 47% de las emisiones de NOx y un 50% de las de partículas procedentes de VCIs en el Area Metropolitana de Barcelona. Esta medida implicaría para el Ayuntamiento más de 6.000 M€ de coste en abonos de transporte.

Actualmente para analizar las partículas se utilizan análisis microscópicos de alta definición para partículas < de 1 µm, como las técnicas EDAX, AFM o FTIR que permiten observar con detalle características tales como la composición, morfología y tamaño de las partículas. El presente proyecto se basó en la caracterización de las partículas y nanoparticulas de los procesos de combustión vehicular, asaderos de alimentos tipo parrillada y en el laboratorio de Optoelectrónica de la Universidad del Quindío, con el fin de analizar las propiedades de las partículas que puedan afectar la salud de los trabajadores o personas expuestas a estas partículas. Se realizó un estudio descriptivo
observacional cuali-cuantitativo y se utilizó el método analítico NIOSH 7300. Los resultados fueron: las muestras no superaron la concentración de 2.4 mg/m3. La concentración de la muestra del asadero fue de 0.01 mg/m3 (DE=215.5, MG=301.6, DGE=3.4 en nanopartículas, y DE=0.46, MG=1.73, DMG=2.7 en micropartículas). La muestra tomada en Optoelectrónica fue de 0.034 mg/m3 (DE=211, MG=348.79, DGE=4.3 en nanopartículas, y DE= 0.36, MG=1.43, DMG=2.6 en micropartículas). Y en la muestra de una avenida
fue de 1.47 mg/m3 (DE=328.07, MG=497.20, DGE=9.4 en nanopartículas, y DE=0.42, MG=1.34, DMG=2.5 en micropartículas). La deposición de estas partículas en el sistema respiratorio humano ocurre en la región inferior del tracto respiratorio y es probable que atraviese las membranas celulares de los tejidos adyacentes, considerándose altamente peligroso para la salud de las personas expuestas.

El problema de la gestión de la basura y los residuos sólidos no ha dejado de ser un problema latente en los países con más o menos recursos del mundo, siendo el problema mayor en los países de Latinoamérica especialmente de Bolivia relacionados principalmente a la recogida y tratamiento posterior considerando las normas técnicas y ambientales. Esta comunicación se sistematiza en base a información secundaria recogida de artículos científicos publicados con experiencias relatadas sobre las últimas tendencias en la recolección y tratamiento de la basura. Se sistematiza así experiencias de la Unión Europea, de Asia y Latinoamérica con énfasis en Bolivia, que nos dan luces claras sobre la gestión de la basura en ciudades modernas y en vías de desarrollo que dependen sobre todo del nivel de educación y motivación de los pobladores con respecto al medio ambiente, en Bolivia denominado Madre Tierra. Se ha encontrado como hallazgos, que los aspectos que motivan para el tratamiento adecuado de la basura no son solamente técnicos sino también socioculturales y dependen mucho del nivel educativo de las personas. Los países desarrollados como las de la Unión Europea son los que llevan la delantera en tema de recogida, tratamiento y nivel educativo de las personas, siendo los países en vías de Desarrollo como por ejemplo Bolivia, que todavía tienen muchos problemas en la recolección y tratamiento de la basura a través de los denominados rellenos sanitarios, influyen para ello varios aspectos relacionados a falta de políticas municipales, regionales, y nacionales relacionados al tema.

Cooperative, connected and automated mobility (CCAM) services along different countries require cross-border solutions to support seamless delivery of services in a multioperator, multi-telco-vendor, and multi-car-manufacturer scenario. The H2020 5GCroCo project will trial 5G technologies in the European cross-border corridor along France, Germany and Luxembourg, as well as in five small-scale trial sites. 5GCroCo analyses three cross-border use cases: tele-operated driving, highdefinition map generation and distribution for autonomous vehicles, and anticipated cooperative collision avoidance (ACCA). This paper presents the infrastructure, control architecture, backend software, and end-to-end service orchestration of the cross-border ACCA use case deployed in the Barcelona small-scale trial site.

The assessment of the remaining useful life due to fatigue in Francis turbine runners implies complex measurements with strain gauges that have to be installed in a submerged and rotating structure, which is excited with high pressure pulsations and strong turbulent flows. Furthermore, the conditioning, storage and transmission of these signals to the stationary frame involves complicated technical solutions. In order to avoid such complex and expensive measurements, in this paper we explore the feasibility of obtaining the strain on the runner with stationary sensors, which can be easily installed and used for a continuous monitoring of the machine. Based on the experimental strain tests performed in a Francis turbine unit, strain on the runner blade is correlated with relevant indicators obtained with stationary sensors. The correlation within indicators is obtained considering linear regression models and improved with artificial intelligence techniques.

The introduction of robotic technology in an existing scenario must be analyzed from the point of view of all the human roles involved in that scenario. In the case of dealing with urban public space, the analysis must consider a large group of citizens who carry out different activities on it. The purpose of this article is to analyze the human roles and the human acceptance when the robotic technology is introduced in the last mile distribution of goods in urban areas. In this work, we start with the description of the Human-Robot Interaction (HRI) scenario for last mile goods delivery, we describe the human roles and we propose a set of relevant indicators to evaluate the human acceptance for this task. Finally, we evaluate the human acceptance through qualitative interviews and quantitative surveys. The study has been done for the peer end-users and bystanders human roles and around 100 people participated.

In this paper, the authors conducted an experiment where a reinforced concrete beam was in-strumented with a single DOFS performing four equal segments externally bonded to the bottom surface of the element. Each segment was adhered to the concrete using a different adhesive. This beam was then loaded, producing expected equal levels of tension in each of the fiber segments for a more direct comparison of the different adhesives performance. The experimental data is subsequently compared with the data provided through more conventional electrical strain gauges that were also deployed in the beam. The effect of alternat-ing the spatial resolution and sampling acquisition is also analyzed. The results provided here will shed a clearer light on how to proceed when applying this promising sensing technique to concrete structures, mainly on what the bonding materials and resolution are concerned.

Current indoor air quality strategies are based on the measurement and control of carbon dioxide (CO2) indoor concentration. Most educational buildings rely only on natural ventilation, making indoor air quality highly dependent on weather conditions. Therefore, to ensure the safety and well-being of students and teachers, it is necessary to determine the factors influencing CO2 concentration in naturally ventilated spaces. The aim of this paper is to estimate the students’ CO2 emission rates in naturally ventilated classrooms using grey box models.

The Earth Surface Mineral Dust Source Investigation (EMIT) acquires new observations of the Earth from a state-ofthe-art, optically fast F/1.8 visible to short wavelength infrared imaging spectrometer with high signal-to-noise ratio and excellent spectroscopic uniformity. EMIT was launched to the International Space Station from Cape Canaveral, Florida, on July 14, 2022 local time. The EMIT instrument is the latest in a series of more than 30 imaging spectrometers and testbeds developed at the Jet Propulsion Laboratory, beginning with the Airborne Imaging Spectrometer that first flew in 1982. EMIT’s science objectives use the spectral signatures of minerals observed across the Earth’s arid and semi-arid lands containing dust sources to update the soil composition of advanced Earth System Models (ESMs) to better understand and reduce uncertainties in mineral dust aerosol radiative forcing at the local, regional, and global scale, now and in the future. EMIT has begun to collect and deliver high-quality mineral composition determinations for the arid land regions of our planet. Over 1 billion high-quality mineral determinations are expected over the course of the one-year nominal science mission. Currently, detailed knowledge of the composition of the Earth’s mineral dust source regions is uncertain and traced to less than 5,000 surface sample mineralogical analyses. The development of the EMIT imaging spectrometer instrumentation was completed successfully, despite the severe impacts of the COVID-19 pandemic. The EMIT Science Data System is complete and running with the full set of algorithms required. These tested algorithms are open source and will be made available to the broader community. These include calibration to measured radiance, atmospheric correction to surface reflectance, mineral composition determination, aggregation to ESM resolution, and ESM runs to address the science objectives. In this paper, the instrument characteristics, ground calibration, in-orbit performance, and early science results are reported.

La Economía Circular (EC) es un concepto recientemente desarrollado que ha ganado un importante reconocimiento en el ámbito político, de negocios y academia, debido a que es considerada una alternativa innovadora aplicable a diversos sectores y que permite satisfacer necesidades de producción y consumo de forma más sostenible. En el sector de la construcción y demolición, la implementación de la EC no ha sido investigada ampliamente y está limitada a enfoques parciales de estudio, abordando especialmente alternativas de recuperación. Existe la necesidad de desarrollar investigaciones más extensas que consideren la aplicación de estrategias circulares en el ciclo de vida completo de las actividades de construcción y demolición. El objetivo central de este trabajo es proveer un análisis de las iniciativas de Economía Circular existentes en España, a nivel estatal y regional, y que tienen una influencia directa en el sector de la construcción y demolición. Para entender el funcionamiento de la EC y las principales iniciativas, se realizó una revisión sistemática de la literatura. Las estrategias identificadas están enfocadas particularmente en la gestión de residuos y el uso de materiales recuperados como materiales secundarios.

Challenging space mission scenarios include those in very low Earth orbits, where the atmosphere creates significant
drag to the S/C and forces their orbit to an early decay. For drag compensation, propulsion systems are needed, requiring propellant to be carried on-board. An atmosphere-breathing electric propulsion system (ABEP) ingests the residual atmosphere through an intake and uses it as propellant for an electric thruster. Theoretically applicable to any planet with atmosphere, the system might allow drag compensation for an unlimited time without carrying propellant.
A new range of altitudes for continuous operation would become accessible, enabling new scientific missions while reducing the required effort for the launcher by achieving these low orbits. Preliminary studies have shown that the collectible propellant flow for an ion thruster in low Earth orbit (LEO) might not be enough, and that electrode erosion due to aggressive gases, such as atomic oxygen, will limit the thruster’s lifetime. In this paper we present the advances
on the design of an inductive plasma thruster (IPT) for the ABEP. The IPT is based on a small-scale inductively heated plasma generator IPG6-S. IPG have the advantage of being electrodeless, and have already shown high electric-tothermal coupling efficiencies using O2 and CO2 as propellant. IPG6-S requires a scaling of the discharge channel to meet with power requirement and expected collected mass flows, as well as optimisation of the accelerating stage, to provide the required thrust to the spacecraft. Tests have been performed to verify some of the parameters and are as well presented within this paper.

The transition to environmentally sustainable societies entails a significant shift in the field of planning process strategy. Strategic Environmental Assessment (SEA) applied to Policies, Plans and Programmes, i.e., planning tools that precede the Project in the decision-making process and surpass it in terms of spatial and subject scope and level of abstraction involved, is recognised internationally as an instrument which is strategic in nature, and is conceived as a flexible framework of key elements, acting strategically in a decision process to enable a facilitating role, ensuring an added-value to decisionmaking. From this perspective, and taking into consideration the current state of environmental assessment in Mexico as a basis of knowledge and understanding, this work attempts to develop a novel methodological approach for the appraisal of infrastructure project planning on renewable energy, addressing SEA and looking upon the current transition process as a matter of interest, as well as the strategies and public policies proposed by governmental bodies; all towards creating mechanisms that allow the effective execution of policies in the field of green energies, acknowledging energy development as a valuable opportunity for improving transparency in strategic decision-making as well as the quality and level of public participation.

La aprobación de un nuevo Código Técnico para la Edificación (CTE) en
España con especificaciones de performance o prestacional, provoca que la sociedad en su conjunto enfrente un cambio de paradigma en la manera de proyectar y desarrollar la edificación. Este proceso de cambio, abordado e impulsado desde la Educación Superior, debe de considerar los medios necesarios y suficientes para poder enfrentar y
desarrollar el actual enfoque prescriptivo y el nuevo enfoque restacional de este CTE, además de contribuir en el presente proceso integrador en el que Europa y España están comprometidos. Este artículo fundamenta la relación o semejanza existente entre el concepto competencia y el concepto performance, la cual establece un punto de partida en la elaboración de aquellas competencias específicas necesarias en la formación de los profesionales usuarios de este nuevo CTE. Dichas competencias permiten establecer criterios en común que aseguren la integración del conocimiento a través de puntos de referencia, basados en resultados del aprendizaje, los que no tienen un carácter normativo, si no de referencia.

En este artículo se ha realizado un estudio de las diferentes fases para la implantación de las metodologías ágiles. Si bien existen publicaciones de casos de éxito en gestión de proyectos de desarrollo software utilizando dichas metodologías, no son tantos los estudios realizados para medir el éxito en otros sectores industriales o incluso diferentes departamentos de las mismas organizaciones. La revisión inicial realizada detalla y lista las diferentes motivaciones y necesidades que impulsan a las organizaciones a cambiar su cultura, procedimientos y maneras de hacer. Seguidamente se considera necesario estudiar las técnicas validadas que permitan seleccionar cuál es la mejor metodología ágil para cada contexto determinado de la organización. Por ello, se analizan si los roles, actividades y herramientas ya validadas dentro de la filosofía “agile” para la gestión de proyectos software, son transferibles y eficaces también para otros departamentos, concretamente para procesos de recursos humanos. La propuesta final del estudio realiza una propuesta de adaptación de dichas metodologías “agile” para los departamentos de recursos humanos con el objetivo de favorecer la usabilidad y la mejora de la organización en su conjunto.

La ejecución de las obras de construcción de un edificio con plantas subterráneas entre medianeras genera afectaciones de diversa consideración a los edificios colindantes y al entorno que lo rodea. Entre los años 2005 y 2010 se detectaron más de un centenar de casos de derrumbes de edificios en España que compartían medianeras con solares contiguos donde se estaba edificando o excavando en ese momento.
Con el fin de establecer un registro detallado de casos de derrumbe y una vinculación entre el problema y las causas que lo producen, se presenta una base de datos de edificios que comparten medianera con solares donde se ejecutan obras de construcción de edificios con plantas subterráneas, formada por 136 casos (55 con derrumbe) y 14 variables o atributos. Esta base de datos puede emplearse con un sistema experto para determinar el método más apropiado de cimentación/contención en cada caso.

Àrees temàtiques de la UPC::Energies::Impacte ambiental
En la actualidad debemos realizar un cambio drástico en la manera de generar y consumir energía, para poder hacer un sistema más sostenible. La transición energética hace frente a los grandes impactos ambientales que se derivan de los combustibles fósiles, pero va más allá. La actual crisis climática nos demuestra que es importante establecer el estado actual, realizar las evaluaciones pertinentes con un enfoque ambiental, utilizando herramientas como el análisis de ciclo de vida (Gabriel, Matos, Castelo & Magrini, 2022). Esta herramienta nos permite mirar que se ha realizado y que propuesta de mejora podríamos tener en toda la cadena de generación de energía y particularizando en el consumo en la pequeña industria, lo que facilita identificar los impactos asociados a los diferentes tipos de energía (Martinez, 2018). Con el proposito de ver que se ha realizado hasta la actualidad y aportar una solución aplicada a las pimes, se desarrolla la presente revisión bibliográfica con la que se logra establecer los alcances que han tenido dichas evaluaciones y el aporte que desde el concepto de ciclo de vida permite entender este sector productivo y su camino a la eficiencia ambiental.

Fire safety community is currently concerned about the response of some widely used insulating materials in case of fire, due to the fact that existing regulations do not show how these materials behave in real conditions, which in some applications may be indeed critical. Within this context, several institutions have recently carried out large-scale tests with the aim of testing such insulator’s contribution to fire growth. In this paper we present a set of large scale tests of compartment and façade fires involving materials and configurations of different nature. Our experiments provided evidence that mineral wool insulator preserves its properties in case of fire, whilst other polymeric-type insulators contribute to fire growth in conditions close to the ones present in real fires.

The use of fiber optic sensors on civil engineering structural health monitoring (SHM) applications have become quite popular for the past two decades. Within this type of sensors however, the study and use of Optical Backscatter Reflectometry (OBR) based Distributed Optical Fiber Sensors (DOFS) is relatively new. In this way, there is still some uncertainty that would allow the use of this technology in a more systematic and standardized way. Some of this uncertainty is related with the long-term reliability behavior of these sensors when applied on the monitoring of a structure under a large number of load cycles. In this way, the authors conducted a laboratory experiment where a reinforced concrete beam was instrumented with a DOFS that was adhered in a way to allow the measuring of strain on four different longitudinal segments on its bottom surface. A fatigue test was then conducted on this element where the inputted load range was the one expected on a standard highway bridge between its self-weight and the additional traffic load. Furthermore, each longitudinal segment of the DOFS was adhered to the concrete using a different adhesive in order to assess the optimal one in these conditions. The obtained data is then compared with strain gauges that are also instrumented on the concrete beam.

The energy consumption of the current building
stock represents about 40% of the total final energy consumption
in Europe. New gamification techniques may play a significant
role in helping users adopt new and more energy efficient
behaviours. This paper presents the advances achieved within the
context of the EU-funded project EnerGAware - Energy Game
for Awareness of energy efficiency in social housing communities.
The main objective of the project, funded by the European Union
under the Horizon2020 programme, is to reduce the energy
consumption and carbon emissions in a sample of European
social housing by changing the energy efficiency behaviour of the
social tenants through the implementation of a serious game
linked to the real energy use of the participants’ homes.

This paper explains the work that we have been doing since 2012 and related with what primary school teachers think about digital games in Catalan classrooms. The main objective is to discover and understand why teachers in general are not using it. While there is increasing research documenting the progress and outcomes of game- based learning and serious games, relatively little attention is paid to the real use of digital games in classrooms and the teachers perceptions. Depth interviews has been done with primary school teachers in order to have attitudes and teachers point of view. As a results of our work we present several teacher barriers to digital game use, for example, an absence of tecnics and generic tools for assessment “in” and “around” digital games.

Global climate change has become increasingly problematic over the past few decades. The construction industry has contributed to greenhouse gas emissions in recent decades. Considering these issues and the high demand for materials in the construction industry, Circular Economy (CE) is considered necessary to keep materials in the loop and extend their useful lives. By providing tangible benefits, Construction 4.0 facilitates the adoption of CE by reducing waste, updating standard work, sharing knowledge, and increasing transparency and stability. This study aims to present a framework for integrating CE and digital tools like Building Information Modeling (BIM) and Virtual Reality (VR) to examine the impact on the construction industry based on stakeholders' perspectives.

Currently Electric Vehicle batteries are considered to reach the End of Lifeonce their State of Health reaches70-80%. However, notions of circular economy suggest that the battery first-life should be extended as much as possible to reduce their environmental impact.Previous works have considered the range limitations of the drivers, arguing that the End of Lifethreshold is too conservative for many cases. However, to validate this statement, the increase of the internal resistance must be addressed. In this work a battery model is used to simulate the battery performance under different driving cycles synthesized from real data. Results show that the functional End of Life is forced by capacity, power or safety related issues.The dominant cause for reaching the End of Life depends highly on the battery size.The under performance is in most cases found after 70-80% State of Health, validating that the first life of most batteries could be extended without affecting the performance of the vehicle.

Interest in operating spacecraft in very low Earth orbits (VLEO), those below approximately 450 km, is growing due to the numerous benefits offered by reducing altitude. For remote sensing and Earth observation applications, improvements in resolution can be achieved or smaller instruments used with associated benefits in cost or mission value. Similarly, for communications applications, link-budgets and data latency can be improved by reducing the operational altitude. However, a key challenge to sustainedoperations in lower altitude orbits is to minimise and compensate for the aerodynamic drag that is produced by the interaction with the residual atmosphere. A principal aim of the DISCOVERER project is to identify, develop, and characterise materials thatcan promote specular reflections of the residual atmosphere in VLEO whilst also remaining resistant to the erosive atomic oxygen that is predominant at these altitudes. In combination with geometric design, such materials would be able to reduce the aerodynamic drag experienced by satellites in orbit and would also be able to generate usable aerodynamic lift enabling novel aerodynamic attitude and orbit control. SOAR (Satellite for Orbital Aerodynamics Research) is a 3U CubeSat that has been designed to investigate the aerodynamic performance of different materials in the VLEO environment and provide validation data for further ground-based experiments. To achieve this, the spacecraft features a set of steerable fins that can expose different materials to the oncoming atmospheric flow. A forward-facing ion and neutral mass spectrometer (INMS) provides in-situ measurements of the atmospheric density and flow composition. SOAR is scheduled for launch to the ISS in March 2021. This paper will present the design of the spacecraft, the experimental method that will be used to investigate the aerodynamic properties of materials in orbit, and will provide an update on the status of the spacecraft as it prepares for launch.

This study presents a tool for decision making called Multicriteria Value Analysis, used
for selection of polymeric materials applied in automotive parts and components. The
tool is built from the methodological framework of Analytical Hierarchy Process (AHP),
to define a hierarchical structure of criteria based on the concept of value, and then
establish the existing preferences among alternatives. Assuming that all possible
alternatives should be polymers and composites which meet the preset quality
specifications, sure there are differences between these alternatives, like: the rate of
weight reduction, mechanical properties, costs material, environmental impacts, etc.
Certainly, Multicriteria Decision Analysis methods are the most suitable in this case,
because they provide us a holistic point of view of the decision problem. In the present
study the methodological framework of Multicriteria Value Analysis is presented. The
proposed criteria structure is validated by weighting them for a hypothetical case study.

Electric vehicles are one promising alternative towards a low carbon electric mobility future with less
dependency on fossil fuels. The European Union automotive industry is a global leader but there currently exists no
single EV targeted legislation that encourages the uptake of these sustainable technologies. In particular, the second
use of degraded electric vehicle batteries in energy storage systems represents emerging economic and environmental
opportunities as well as legal concerns that need to be addressed and managed in a timely manner. Hence, a more
efficient regulatory framework in place will further increase the integration of renewable energy sources into the power
system while at the same time creating a level playing field for an electric mobility transition in the European Union.

As a result of monitoring thousands of electric vehicle charges around Europe, this study builds statistical distributions that model the amount of energy necessary for trips between charges, showing that most of trips are within the range of electric vehicle even when the battery degradation reaches the end-of-life, commonly accepted to be 80% State of Health. According to these results, this study analyses how far this End-of-Life can be pushed forward using statistical methods and indicating the provability of failing to fulfill the electric vehicle (EV) owners’ daily trip needs.

In very low Earth orbits (VLEO), below 450 km altitude, the aerodynamic properties of satellites are primarily determined by the flow regime, free molecular flow, and the interaction of atomic oxygen with the surfacesof the spacecraft. The Rarefied Orbital Aerodynamics Research (ROAR) facility is a novel experimental facility designed to simulate these conditions in a controlled environment to characterise the aerodynamic properties of materials. It is built as part of DISCOVERER, a Horizon 2020 project developing the different technologies required to enable the sustainable operation of satellites in VLEO. Because ROAR isn’t intended to perform erosion studies, it differs quite significantly from other atomic oxygen exposure experiments and its characteristics are discussed in this work. ROAR consists of an ultrahigh vacuum system, responsible for generating the free molecular flow conditions, a source of hyperthermal oxygen atoms at orbital velocities, and mass spectrometers; the latter used to characterise the gas-surface interactions, and therefore the material’s aerodynamic performance. This paperincludesa description of ROAR’s main components, together with the experimental methodology for materials testing and early results. Among the main parameters to be considered are atomic oxygen flux, beam shape and energy spread, mass resolution, and signal-to-noise ratio.

Durability in aggressive environments is an important factor to extend the service life of concrete and the use ternary blended cements (limestone filler + calcined clays) can contribute to this purpose. In sulfate environments, the effects of supplementary cementing materials depend on the concentration, Portland cement and the progress of hydration reactions. Low level of limestone filler replacement influences the stabilization of AFt due to formation of monocarboaluminate, but high replacement increases the effective w/c and the capillary porosity promoting sulfate penetration. The use of active pozzolans suppresses the sulfate attack by minimizing both ettringite and gypsum formation. It is generally assumed that curing prior to sulfate exposure should be extended to allow the development of the pozzolanic reaction and subsequent reduction of portlandite content, pore size structure refinement and permeability reduction. However, in most field applications, concretes exposed to sulfate attack are cast in situ and thus, these are exposed to sulfate since early ages. This paper evaluatesthe sulfate resistance of an illitic-calcined clay and limestone filler when the cement is exposed immediately to aggressive environments. In this paper, the external sulfate resistance of blended cements containing 30% replacement of limestone filler and/or calcined clay (C30F, C30CC and C15F15CC) are analysed. Two different calcined clays from Buenos Aires, Argentina were selected. Mortar prisms and cement paste cubes were fabricated and exposed to a sodium sulfate solution after 2 days. Comparison ofsulfate resistance was based on the expansion, mass variation, visual appearance and compressive strength . Furthermore, the evolution of microstructure of blended cements exposed to sodium sulfate solution was characterized by XRD tests on the external surface and the core of cementblended pastes.

DISCOVERER is a €5.7M European Commission funded Horizon 2020 project developing technologies to enable commercially-viable sustained-operation of satellites in very low Earth orbits. Why operate closer to the Earth? For communications applications latency is significantly reduced and link budgets improved, and for remote sensing improved link budgets allow higher resolution or smaller instruments, all providing cost benefits. In addition, all applications benefit from increased launch mass to lower altitudes, whilst end-of-life removal is ensured due to the increased atmospheric drag. However, this drag must also be minimised and compensated for. One of the key technologies being developed by DISCOVERER are materials thatencourage specular reflection of the residual atmosphere at these altitudes. Combined with appropriate geometric designs these can significantly reduce drag, provide usable lift for aerodynamic attitude and orbit control, and improve the collection efficiency of aerodynamic intakes for atmosphere breathing electric propulsion systems, all of which arebeing developed as part of DISCOVERER. The paper provides highlights from the developments to date, and the potential for a new class of aerodynamic commercial satellites operating at altitudes below the International Space Station.

With the current demand of flexibility to hydraulic turbines, these are working under off-design conditions more than ever. Under these conditions different complex hydraulic phenomena appear, especially in Francis turbines, affecting the machine stability as well as reducing the useful life of its components. Hence, it is desirable to detect in real-time these hydraulic phenomena to assess the operation of the machine. In addition, the position and type of sensor to detect these phenomena is a key point for the monitoring of Francis units. In this paper, a large medium-head Francis turbine was instrumented with several sensors such as accelerometers, proximity probes, strain gauges, pressure sensors and a microphone. Results obtained with the different sensors in different locations are compared to know which hydraulic phenomenon is detected with every sensor. Furthermore, different signal analysis techniques are also compared. With this information, monitoring systems can be optimized with the most convenient sensors, locations and signal analysis techniques, reducing its difficulty to install and economic cost.

Under COVID scenario, it has been observed that the constraints derived from remote teaching makes harder an already challenging task: the achievement of teamwork skills and their assessment. This study, which is part of the UPC-ICE “EQUIPA'T” teaching innovation project, aims to design a new protocol for the development of academic projects and the individualized evaluation of university students regardless the field of knowledge within engineering. To that end, eight functionalities have been identified: (i) quantification of the individual contribution; (ii) group dynamics and individual roles; (iii) internal team management; (iv) communication; (v) creativity (brainstorming / concept map); (vi) design thinking; (vii) repository; (viii) content development (previous ideas about concepts). For each of them, a series of indicators, activities, and tools have been defined to allow the development of the aforementioned functions in face-to-face and remote environments. In addition, an analysis has been carried out to determine the implementation of the protocol by professors in the pilot stage of the project.

Energy Performance Contracts (EPC) are contractual agreements between beneficiaries and energy service providers, where budgets are established in relation to a determined level of energy performance. Hence, the problem of forecasting the energy performance of buildings in the EPC tendering phase becomes relevant for the reliability of the overall contract. Unfortunately, fuzziness and incompleteness often characterize the technical information supporting EPC call for tenders. Furthermore, buildings that are the subjects of EPCs are normally quite complex public buildings (hospitals, schools, etc.) usually relatively old and not technically well known. Gathering information about such buildings is a time consuming and expensive process within the usually short time frame of EPC call for tenders. This paper investigates the application of Grey-Box modelling to the energy performance forecast of complex buildings, in perfectly and poorly informed operational cases. The proposed methodology offers a potential solution to the EPC operational requirements since it requires a substantially reduced parameter set. Results show that the proposed Grey-Box modelling can be used to arrange a calibration set-up with good forecasting performance. Furthermore, Grey-Box modelling allows an effective management of the information uncertainty usually present in the EPC context.

To understand the effect of rotation in the dynamic response of pump-turbine runners, simplified models such as disk-like structures can be used. In previous researches the natural frequencies and mode shapes of rotating disk-like structures submerged and confined have been analysed from the rotating frame. Nevertheless to measure these parameters experimentally from the rotating point of view can be a difficult task, since sensors have to withstand with large forces and dynamic loads. In this paper the dynamic response of rotating disk-like structures is analysed from the stationary frame. For this purpose an experimental test rig has been used. It consists on a disk confined that rotates inside a tank. The disk is excited with a PZT attached on it and the response is measured from both rotating frame (with miniature accelerometers) and from the stationary frame (with a Laser Doppler Vibrometer). In this way the natural frequencies and mode shapes of the rotating structure can be determined from the stationary reference frame. The transmission from the rotating to the stationary frame is compared for the case that the rotating structure rotates in a low density medium (air) and in a high density medium (water).

Spacecraft operations below 450km, namely Very Low Earth Orbit (VLEO), can offer significant advantages over traditional low Earth orbits, for example enhanced ground resolution for Earth observation, improved communications latency and link budget, or improved signal-to-noise ratio. Recently, these lower orbits have begun to be exploited as a result of technology development, particularly component miniaturisation and cost-reduction, and concerns over the increasing debris population in commercially exploited orbits. However, the high cost of orbital launch and challenges associated with atmospheric drag, causing orbital decay and eventually re-entry are still a key barrier to their wider use for large commercial and civil spacecraft. Efforts to address the impact of aerodynamic drag are being sought through the development of novel drag-compensation propulsion systems and identification of materials which can reduce aerodynamic drag by specularly reflecting the incident gas. However, the presence of aerodynamic forces can also be utilised to augment or improve spacecraft operations at these very low altitudes by providing the capability to perform coarse pointing controland trim orinternalmomentum management for example. This paper presents concepts for the advantageous use of spacecraft aerodynamics developed as part of DISCOVERER, a Horizon 2020 funded project with the aim to revolutionise Earth observation satellite operations in VLEO. The combination of novel spacecraft geometries and use of aerodynamic control methods are explored, demonstrating the potential for a new generation of Earth observation satellites operating at lower altitudes.

En 2011 el MIT patentó una rueda de bicicleta capaz de albergar diversos elementos de manera que permiten transformar una bicicleta convencional en una eléctrica sin necesidad de instalaciones complejas ni cableado, con sólo cambiar la rueda trasera. La rueda en cuestión además del motor eléctrico, está equipada con GPS y diferentes sensores que permiten al ciclista tener conocimiento de la calidad del aire, la distancia recorrida, etc. Dispone también de conexión inalámbrica mediante la cual se puede sincronizar con un smartphone mediante una aplicación móvil, convirtiendo una bicicleta convencional en una “bicicleta inteligente”. De este modo permite al usuario elegir una configuración de la energía, revisar el historial de recorridos, la contaminación del aire y crear un perfil para interacciones sociales. En este trabajo se estudia la viabilidad técnica, económica y ambiental del proyecto de fabricación de tales ruedas de bicicleta inteligente. Asimismo, se presenta cuál sería el concepto de negocio de dicho proyecto aplicado al mercado español. Finalmente, también se ha analizado el impacto ambiental de una bicicleta inteligente en comparación con el de otros vehículos urbanos.

Aerodynamic forces have often been proposedas a possible means to perform a variety of different attitude and orbit control manoeuvres in very low Earth orbits including pointing control, constellation and formation management, and re-entry interface targeting. However, despite interest and numerous studies conducted in this area there is has been lack of on-orbit demonstration of these manoeuvres beyond simple proof of aerostability and some operational use of differential drag for constellation maintenance. SOAR (Satellite for Orbital Aerodynamics Research) is a CubeSat mission and part of DISCOVERER, a Horizon 2020 funded project to develop technologies to enable sustained operation of Earth observation satellites in very Low Earth Orbits. SOAR is due to be launched in 2020 with the primary aim to investigate the interaction between different materials and the atmospheric flow regime in very low Earth orbits. This satellite, with its set of rotating aerodynamic fins, also offers the unique opportunity to demonstrate and test novel aerodynamic control methods in the very-low Earth orbit (VLEO) environment. This paper presents the approach to demonstrate novel aerodynamic control methods in-orbit thatwill be used on the experimental SOAR Cubesat. The aerodynamic manoeuvres and associated control methods selected for demonstration are first described. Simulations of the aerodynamic control manoeuvres and expected satellite dynamic behaviour are also presented, demonstrating potential advantages for spacecraft operations which can be achieved by utilising the natural aerodynamic forces present at these lower orbital altitud

Shared ride-hailing services are discreetly emerging in cities all over the world, with the purpose of providing a transport service more flexible than the public bus and cheaper than the regular taxi. Hence, it is important to identify and include the relevant and key fa ctors of such a service to ensure its success. The aim of this study was to investigate the utility of a commu ting on-demand shared ride-hailing service and determine the design factors for an appropriate ser vice from the users’ perspective. During one week, a pilot of a shared ride-hailing service to commute f rom the city centre of Barcelona to the most western district of the city was conducted. Although the s ample used in this study was modest in scale, it enabled to draw preliminary conclusions. Users valued very positively the comfort provided but they would not pay more than the double of the price of the public transport. This indicates that despite having a high number of users, such a low price could c omplicate the profitability of the service unless it was partially subsidized.

Determining the dynamic response of submerged and confined disk-like structures is of interest in the hydraulic turbines field. Disks present similar dynamic characteristics than hydraulic turbine runners, especially in the mode-shapes associated with each natural frequency. The dynamic response of submerged structures is heavily affected by the added mass and damping as well as the proximity of solid boundaries. In all studies the solid boundaries are commonly considered completely rigid, however in real cases this is not always true. This fact occurs in some hydraulic turbines where the casing is not completely stiff and it may have some dynamic response in the frequency range of the runner, which may affect its dynamic behavior. To determine the influence of the casing stiffness on a vibrating disk submerged in water an experimental investigation has been carried out. A test rig consisting of a disk attached to a shaft inside a cylindrical tank closed with two different covers with different stiffness has been built up. The disk was impacted using a hammer and both disk and covers responses were measured with different accelerometers. Pressure sensors mounted on the covers have also been used. Natural frequencies of the disk have been obtained, compared and discussed for different disk to cover distances.

Currently, the most developed societies invest in science and technology, due to the generation of knowledge and innovations, which apply scientific techniques and technological knowledge, fundamental for economic growth and social progress, for which it is necessary to periodically generate the mapping of the level of maturity of projects. The objective of the article is to map the maturity level of technological innovation within a University of Arequipa, Peru, for this, two tools have been used for its measurement: Technology Readiness Levels and the Minimum Viable Innovation System that allows validating the main hypotheses of value and build a final product. These tools were applied through a survey of the leaders of 186 projects financed by the University. The results of both measurements were compared and showed that out of the total of the responses obtained, they showed an average level of technological innovation, which is why it concludes that the technological innovation projects at the University of the case study do not go beyond a level 4 technology maturation, that is, an incipient innovation process.

Big data analysis is becoming an increasing field of interest for research to analyse, identify and predict final user’s behaviour. For this reason, in the energy sector, smart metering is generally used to find new business opportunities and, theoretically, it is said that it could also help to fight energy poverty issues. Nonetheless, when tackling social injustice issues, the deployment of massive technology might also bring other side effects. This study analyses the capability of smart metering to mitigate energy poverty in Europe according to the current approaches of projects and the risks it might bring to the more vulnerable layers of our society.

The DISCOVERER project commenced in 2017 with the aim to advance the development of key technologies to enable the commercially viable, sustained operation of satellites in very low Earth orbits (VLEO). Funded by the European Commission through Horizon 2020, the project ends this month. This paper presents an overview of the key achievements and current status of the project. The project set out to advance the development of, and demonstrate, several technologies with the long-term aim
of enabling the commercial use of VLEO. These technologies include:
1. aerodynamic materials which encourage specular scattering of the incoming flow to minimise drag and increase the performance of aerodynamic surfaces in the highly rarefied flows experienced in VLEO
2. aerodynamic attitude control methods to compensate for the dynamic flow environment, especially lower in the VLEO altitude range
3. atmosphere breathing electric propulsion (ABEP), combining an optimised atmospheric intake with advanced RF Helicon-based plasma thruster, for drag compensation
DISCOVERER’s test satellite, the Satellite for Orbital Aerodynamics Research or SOAR, was deployed from the International Space Station in June 2021 and re-entered the atmosphere in March 2022. The primary aim was to measure the induced drag and lift on different aerodynamic materials candidates in VLEO by exposing panels, coated in various novel and control materials, to the flow at different orientations whilst observing the induced attitude and orbit perturbations produced. Early analysis of the results from the mission shows promising results for the novel materials developed as part of the project. Parallel studies on the long-term survivability of these materials to the space environment have been on-going through exposure tests on the exterior of the International Space Station through the MISSE programme.
The project has also been developing a ground-based facility, the Rarefied Orbital Aerodynamics Research facility, to characterise the gas surface interaction properties of materials to atomic oxygen at orbital velocities. Characterisation of the facility itself is on-going. In support of ABEP technology, the experimental development and characterisation of an RF Helicon-based plasma thruster has been on-going, along with detailed computational modelling of aerodynamic intakes. Whilst the thruster has already been operated, current work focusses on the characterisation of its performance. Finally, work to place these technological developments into context has also been progressed. On overview of the overall achievements in this area is provided, including business modelling of the VLEO market ecosystem, which identifies the enormous market potential for VLEO missions.

The global trend on energy integration and building efficiency is making both researchers and developers look for technical solutions to use façade surfaces for electricity and/or domestic hot water production. These applications improve the energy performance of the building, but the integration of solar photovoltaic panels or solar thermal collectors into the façade may block visibility to the exterior and may prevent natural light from entering the building, both important comfort factors for building users.
This paper presents the preliminary results on the assessment of the thermal performance of a double-skin facade (DSF) with a venetian blind-type of structure used as a solar thermal collector to heat up a circulating fluid by means of computational fluid dynamics (CFD). This type of heat exchange structure would allow for energy recovery and exterior views simultaneously, and can be easily integrated into the façade aesthetical design. For the purposes of this study, the modeled façade is set to be located in Barcelona (Spain), where large solar gains are a constant condition throughout the year, and such large semi-transparent areas as this type of façades can produce significant over-heating in buildings, even during the winter.
For the studied façade both the reductions in radiative heat gains entering the building and the heat recovery are evaluated for summer meteorological and solar radiation conditions and numerical results obtained are compared with previous results reported by our research group on a similar DSF model without a façade integrated thermal system.
