Sensitivity analysis of maximum circulation of wake vortex encountered by en-route aircraft
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-16)
Article
Open AccessWake 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
(2021-11)
Article
Open AccessIn 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
(2020)
Article
Open AccessThe Universitat Politecnica de Catalunya (UPC), the Physikalisch-Technische Bundesanstalt (PTB) and the German Federal Office of Radiation Protection (BfS) have analysed the response of a 2”x2” (diameter x height) NaI and ... -
Active flow control optimisation on SD7003 airfoil at pre and post-stall angles of attack using synthetic jets
(2021-06-10)
Article
Restricted access - publisher's policyThe use of Active Flow Control (AFC) technologies to modify the forces acting on streamlined bodies is one of the most active research fields in aerodynamics. For each particular application, finding the optimum set of AFC ... -
Determination of the operational parameters for the manufacturing of spherical PVP particles via electrospray
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02)
Article
Open AccessThis work aims at bridging experimental and numerical approaches to determine the optimal operating parameters for the fabrication of well-shaped polyvinylpyrrolidone (PVP) particles via electrohydrodynamic atomization. ... -
Flight planning in multi-unmanned aerial vehicle systems: Nonconvex polygon area decomposition and trajectory assignment
(SAGE PUBLICATIONS INC, 2021-02-25)
Article
Open AccessNowadays, it is quite common to have one unmanned aerial vehicle (UAV) working on a task but having a team of UAVs is still rare. One of the problems that prevent us from using teams of UAVs more frequently is flight ... -
Counter a drone in a complex neighborhood area by Deep Reinforcement Learning
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-04-18)
Article
Open AccessCounter-drone technology by using artificial intelligence (AI) is an emerging technology and it is rapidly developing. Considering the recent advances in AI, counter-drone systems with AI can be very accurate and efficient ... -
The effect of LCC market entry on dominant FSC's price into long haul sector: A case of Norwegian competition on British Airways' prices on selected transatlantic routes
(2021-03)
Article
Restricted access - publisher's policyThe concept of long-haul low-cost operations has become somewhat appealing in the airline industry in recent years. In Europe, the rapid expansion of low-cost carrier Norwegian that entered the long-haul markets from several ... -
Traffic synchronization in terminal airspace to enable continuous descent operations in trombone sequencing and merging procedures: An implementation study for Frankfurt airport
(2020-12)
Article
Restricted access - publisher's policyThis paper proposes to enhance the current tromboning paradigm with a four dimensional trajectory negotiation and synchronization process with the aim to maximise the number of neutral Continuous descent operations (CDOs, ... -
Feature selection model based on EEG signals for assessing the cognitive workload in drivers
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-10-17)
Article
Open AccessIn recent years, research has focused on generating mechanisms to assess the levels of subjects’ cognitive workload when performing various activities that demand high concentration levels, such as driving a vehicle. These ... -
