Enriched finite element approach for modeling discontinuous electric field in multi-material problems
(Elsevier, 2023-11-01)
Article
Open AccessThis work is devoted to developing an efficient and robust technique for accurately capturing the electric field in multi-material problems. The formulation is based on the finite element method enriched by the introduction ... -
CO2 and non-CO2 balanced environmental scores module for flight performance evaluation and optimisation
(Institute of Physics (IOP), 2023-06-28)
Article
Open AccessThe SESAR2020 exploratory research (ER4) programme CREATE (Grant 890898) developed a climate and weather aware Concept of Operations (ConOps) which encompasses a multi-aircraft 4D trajectory optimisation framework, which ... -
Methodological framework for a deeper understanding of airline profit cycles in the context of disruptive exogenous impacts
(2023-01)
Article
Open AccessThis paper combines the k-means clustering method in combination with PCA and the system dynamic modeling approach to derive a better insight into the behavior of airline profitability during the time span of 1995 until ... -
Interacting multiple model filtering for aircraft guidance modes identification from surveillance data
(2023-06-01)
Article
Open AccessAccurate and reliable trajectory prediction (TP) is required in several air traffic management systems. Estimating the aircraft trajectory in a vertical plane typically requires the knowledge of a pair of operational ... -
Feasibility study of aerocapture at Mars with an innovative deployable heat shield
(2021-06-28)
Article
Open AccessPerforming orbital insertion around Mars using aerocapture instead of a propulsive orbit insertion maneuver allows the saving of resources and/or the increase of the payload mass fraction. Aerocapture has never been employed ... -
Enhancing drones for law enforcement and capacity monitoring at open large events
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-17)
Article
Open AccessPolice tasks related with law enforcement and citizen protection have gained a very useful asset in drones. Crowded demonstrations, large sporting events, or summer festivals are typical situations when aerial surveillance ... -
Impact of Covid-19 on the aviation industry: an overview of global and some local effects
(2022-12-27)
Article
Open AccessThe COVID-19 pandemic temporarily paralysed demand for air travel causing long-term implications for all industry stakeholders involved. Nobody was spared, and without government support, many airlines, airports and air ... -
Monitoring tomato leaf disease through convolutional neural networks
(2023-01-01)
Article
Open AccessAgriculture plays an essential role in Mexico’s economy. The agricultural sector has a 2.5% share of Mexico’s gross domestic product. Specifically, tomatoes have become the country’s most exported agricultural product. ... -
Time-based-fuel-efficient aircraft descents: thrust-idle descents along re-negotiated routes vs. powered descents along published routes
(2023-01-02)
Article
Open AccessWe address the situation where required times of arrival (RTAs) are assigned outside the feasible time window that allows aircraft to fly energy-neutral continuous descent operations (CDOs). Two strategies to achieve these ... -
An enriched finite element/level-set model for two-phase electrohydrodynamic simulations
(2023-01-04)
Article
Open AccessIn this work, a numerical model for the simulation of two-phase electrohydrodynamic (EHD) problems is proposed. It is characterized by a physically consistent treatment of surface tension as well as a jump in the electric ... -
Multi-objective multi-scale optimization of composite structures, application to an aircraft overhead locker made with bio-composites
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-12-28)
Article
Open AccessThe use of composite materials has grown exponentially in transport structures due to their weight reduction advantages, added to their capability to adapt the material properties and internal micro-structure to the ... -
Improving glass-fiber epoxy composites via interlayer toughening with polyacrylonitrile/multiwalled carbon nanotubes electrospun fibers
(Wiley, 2022-11)
Article
Open AccessThe development of innovative engineered epoxy composites aiming to manufacture cost-efficient materials with reduced weight and enhanced physical properties remains as a current industrial challenge. In this work we report ...
