  • The geometry of Hermitian self-orthogonal codes 

    Ball, Simeon Michael; Vilar Algueró, Ricard (Elsevier, 2021-12-20)
    Article
    Restricted access - publisher's policy
    We prove that if n>k2 then a k-dimensional linear code of length n over Fq2 has a truncation which is linearly equivalent to a Hermitian self-orthogonal linear code. In the contrary case we prove that truncations of linear ...
  • Polyurethane shape memory filament yarns: Melt spinning, carbon-based reinforcement, and characterization 

    Gonzalez Bertran, Judit; Ardanuy Raso, Mònica; Gonzalez Colominas, Marta; Rodriguez, Rosa; Jovancic, Petar (2022-07-26)
    Article
    Open Access
    The aim of this work was to develop and characterize polyurethane-based shape memory polymer filament yarns of a suitable diameter and thermo-mechanical performance for use in tailored multi-sectorial applications. Different ...
  • Early fault detection in the main bearing of wind turbines based on Gated Recurrent Unit (GRU) neural networks and SCADA data 

    Encalada-Dávila, Ángel; Moyón, Luis; Tutivén Gálvez, Christian; Puruncajas Maza, Bryan; Vidal Seguí, Yolanda (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    Failures in the main bearings of wind turbines are critical in terms of downtime and replacement cost. Early diagnosis of their faults would lower the levelized cost of wind energy. Thus, this work discusses a gated recurrent ...
  • Event-based line SLAM in real-time 

    Chamorro Hernández, William Oswaldo; Solà Ortega, Joan; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    Event-based cameras generate asynchronous streams of events, triggered proportionally to the logarithmic change of brightness in the scene. These cameras have very low latency and high dynamic range suitable to address ...
  • Análisis colorimétrico de estructuras de fondo de ojo mediante retinografía multiespectral 

    Burgos Fernández, Francisco Javier; Alterini, Tommaso; Díaz Douton, Fernando; Pujol Ramo, Jaume; Vilaseca Ricart, Meritxell (2022)
    Conference report
    Open Access
    El análisis del fondo del ojo es crucial para prevenir enfermedades retinianas y coroideas ya que la mayoría no causan síntomas en etapas tempranas. Tratarlas cuando aparecen los primeros indicios es fundamental para evitar ...
  • Bromine etching of kesterite thin films: perspectives in depth defect profiling and device performance improvement 

    Tiwari, Kunal; Jiménez Arguijo, Alex; Giraldo, Sergio; Placidi, Marcel Jose; Calvo-Barrio, L; Fonoll Rubio, Robert; Izquierdo Roca, Víctor; Sánchez González, Yudania; Perez Rodriguez, Alejandro; Saucedo Silva, Edgardo Ademar; Jehl Li-Kao, Zacharie (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report

    Using a controlled bromine etching on kesterite absorbers, two major results are obtained. We establish the first defect depth profiling and secondary phases depth profiling of a state of the art Cu2ZnSnSe4 (CZTSe) film ...
  • Modelling the effect of in-soil temperature and relative humidity on performance of PET strap soil reinforcement products 

    Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard (Australian Geomechanics Society, 2022)
    Conference lecture
    Restricted access - publisher's policy
    Polyester (PET) strap reinforcement materials are now used routinely as soil reinforcement for mechanically stabilized earth (MSE) walls. The important role of temperature and relative humidity on the chemical degradation ...
  • Design and implementation of a very-low-power wireless network of sensors in an underground utility tunnel for medium and high voltage transmission lines 

    Rachid, Adil; López Martínez, Antonio Miguel; Moreno García, Sebastián (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference report
    Restricted access - publisher's policy
    The reliability of the electrical network and the need to minimize economic losses due to unexpected power outages have led electricity distribution companies to introduce diagnostic and preventive maintenance programs to ...
  • Diagnosis electromechanical system by means CNN and SAE: an interpretable-learning study 

    Arellano Espitia, Francisco; Delgado Prieto, Miquel; Martínez Viol, Víctor; Saucedo Dorantes, Juan Jose; Osornio Rios, Roque A. (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference report
    Open Access
    Cyber-physical systems are the response to the adaptability, scalability and accurate demands of the new era of manufacturing called Industry 4.0. They will become the core technology of control and monitoring in smart ...
  • Mechanism for financing the accumulated debt of utility services water, electricity and gas as a result of the COVID-19 

    Verdejo, Humberto; Becker, Caroline; García Muñoz, Fernando Esteban; Holtz, Mauricio; Tobar, Francisco (Multidisciplinary Digital Publishing Institute (MDPI), 2022-03-19)
    Article
    Open Access
    The effects associated with the pandemic of COVID-19 have left several consequences. The large confinements have caused formal and independent job losses. Therefore, families have been forced to prioritize their monthly ...
  • Anonymizing trajectory data: limitations and opportunities 

    Guerra Balboa, Patricia; Miranda Pascual, Àlex; Parra Arnau, Javier; Forné Muñoz, Jorge; Strufe, Thorsten (AAAI Press (Association for the Advancement of Artificial Intelligence), 2022)
    Conference lecture
    Restricted access - publisher's policy
    A variety of conditions and limiting properties complicate the anonymization of trajectory data, since they are sequential, high-dimensional, bound to geophysical restrictions and easily mapped to semantic points of interest ...
  • Extension of 2D shallow water models to hydrological modelling 

    Cea, Luis; Bladé i Castellet, Ernest; García Feal, Orlando; Sanz Ramos, Marcos; Gómez Gesteira, Moncho; Farfán Durán, Juan Fernando (International Association for Hydro-Environment Engineering and Research (IAHR), 2022)
    Conference report
    Restricted access - publisher's policy
    In this paper we discuss some critical aspects that should be considered in order to extend and apply a numerical model based on the 2D shallow water equations(2D-SWE) to distributed hydrological modelling. We also detail ...
