    Article
    Open Access
    There is a group of users within the vehicular traffic ecosystem known as Vulnerable Road Users (VRUs). VRUs include pedestrians, cyclists, motorcyclists, among others. On the other hand, connected autonomous vehicles ...
  • A New Hybrid Optimization Method, Application to a Single Objective Active Flow Control Test Case 

    Coma Company, Martí; Monshi Tousi, Navid; Pons Prats, Jordi; Bugeda Castelltort, Gabriel; Bergadà Granyó, Josep Maria (Multidisciplinary Digital Publishing Institute, 2022-04-12)
    Article
    Open Access
    Genetic Algorithms (GA) are useful optimization methods for exploration of the search space, but they usually have slowness problems to exploit and converge to the minimum. On the other hand, gradient based methods converge ...
  • RNN-CNN hybrid model to predict C-ATC CAPACITY regulations for en-route traffic 

    Mas Pujol, Sergi; Salamí San Juan, Esther; Pastor Llorens, Enric (Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-01)
    Article
    Open Access
    Meeting the demand with the available airspace capacity is one of the most challenging problems faced by Air Traffic Management. Nowadays, this collaborative Demand–Capacity Balancing process often ends up enforcing Air ...
  • Implementing mitigations for improving societal acceptance of urban air mobility 

    Cetin, Ender; Cano Gento, Alicia; Deransy, Robin; Tres Martínez, Sergi; Barrado Muxí, Cristina (Multidisciplinary Digital Publishing Institute (MDPI), 2022-01-18)
    Article
    Open Access
    The continuous development of technical innovations provides the opportunity to create new economic markets and a wealth of new services. However, these innovations sometimes raise concerns, notably in terms of societal, ...
  • An optimization method of formation flight for minimizing fuel consumption 

    Hu, Yue; Dai, Wei; Prats Menéndez, Xavier (2021-04)
    Article
    Open Access
    A method for formation flight trajectory optimization was established. This method aims at minimizing fuel consumption of a two-aircraft formation flight,without changing the original trajectory of the leader. Candidate ...
  • Sensitivity-based non-linear model predictive control for aircraft descent operations subject to time constraints 

    Dalmau Codina, Ramon; Prats Menéndez, Xavier; Baxley, Brian (Multidisciplinary Digital Publishing Institute (MDPI), 2021-12)
    Article
    Open Access
    The ability to meet a controlled time of arrival while also flying a continuous descent operation will enable environmentally friendly and fuel efficient descent operations while simultaneously maintaining airport throughput. ...
  • Multi-Robot workspace division based on compact polygon decomposition 

    Skorobogatov, Georgy; Barrado Muxí, Cristina; Salamí San Juan, Esther (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Article
    Open Access
    In this work, we tackle the problem of multi-robot convex workspace division. We present an algorithm to split a convex area among several robots into the corresponding number of parts based on the area requirements for ...
  • Improving real-time drone detection for counter-drone systems 

    Cetin, Ender; Barrado Muxí, Cristina; Pastor Llorens, Enric (2021-06-16)
    Article
    Open Access
    The number of unmanned aerial vehicles (UAVs, also known as drones) has increased dramatically in the airspace worldwide for tasks such as surveillance, reconnaissance, shipping and delivery. However, a small number of ...
  • Fast-time demand-capacity balancing optimizer for collaborative air traffic flow management 

    Xu, Yan; Camargo Forero, Leonardo; Prats Menéndez, Xavier (American Institute of Aeronautics and Astronautics (AIAA), 2021-08)
    Article
    Open Access
    This paper builds on top of a collaborative ATFM framework previously published, which demonstrated a potential in significant pre-tactical system delay reduction over the current European ATFM practices. In this paper, ...
  • Sensitivity analysis of maximum circulation of wake vortex encountered by en-route aircraft 

    Rojas Gregorio, José Ignacio; Melgosa Farrés, Marc; Prats Menéndez, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-16)
    Article
    Open Access
    Wake vortex encounters (WVE) can pose significant hazard for en-route aircraft. We studied the sensitivity of wake vortex (WV) circulation and decay to aircraft mass, altitude, velocity, density, time of catastrophic wake ...
  • Automated sequencing and merging with dynamic aircraft arrival routes and speed management for continuous descent operations 

    Sáez García, Raúl; Polishchuk, Tatiana; Schmidt, Christiane; Hardell, Henrik; Smetanová, Lucie; Polishchuk, Valentin; Prats Menéndez, Xavier (2021-11)
    Article
    Open Access
    In this paper, we present a novel methodology to manage arrival traffic in terminal airspace. We define two areas around the airport, aiming to efficiently schedule incoming traffic. A four-dimensional (4D) trajectory ...
  • Comparison of airborne radiation detectors carried by rotary-wing unmanned aerial systems 

    Vargas Drechsler, Arturo; Costa Vargas, Daniel; Macias López, Miquel; Royo Chic, Pablo; Pastor Llorens, Enric; Luchkov, Maksym; Neumaier, Stefan; Stöhlker, Ulrich; Luff, Roger (2020)
