Monitoring the behavior of people in complex environments has gained much attention over the past years. Most of the current approaches rely on video cameras mounted on buildings or pylons and people are detected and tracked in these video streams. The presented approach is intended to complement this work. The monitoring of people is based on aerial image sequences derived with camera systems ...

Logistics support is a key element of aircraft transportation systems. This paper is concerned with the impact of aircraft spares provisioning decisions on the availability of aircraft. Spares provisioning in this context is complicated by the fact that spares may be shared across aircraft and that aircraft may have redundant systems. In addition, decisions concerning aircraft spares support re...

A method of noise reduction proposed for the next generation aircraft is to shield from propulsion system, by positioning source over a wing or another surface. In this paper, an approximate analysis developed acoustic field far circular placed near edge semi-infinite plate, model problem shielding and scattering trailing edge. The approximation small radius found be accurate when compared full...

We review the available information on the mechanisms of lightning-aircraft interactions based primarily on studies involving four different instrumented aircraft. Further, we present available statistics on lightning-related aircraft incidents as a function of aircraft altitude and of ambient temperature. Finally, we examine the most significant aircraft and launch vehicle accidents attributed...

ly, the runway scheduling problem (RSP) can be thought of as a job shop scheduling problem [11] with precedence and release time constraints, where the objective is to sequence a set of jobs (aircraft) in a particular order to be processed by a processor (runway) so that some cost function is minimized. For the runway scheduling problem, one wants to find an efficient schedule for aircraft to u...

Dispatch reliability is the key parameters to reflect the overall reliability of civil aircraft, and it is also the important technical parameters needs to be considered in the original design of civil aircraft. According to the actual delay rate data of airlines, combined with the relationship between delay rate and dispatch reliability, from the perspective of civil aircraft design, author fi...

ACFA 2020 (active control for flexible aircraft) is a collaborative research project funded by the European Commission under the seventh research framework programme. The project deals with innovative active control concepts for 2020 aircraft configurations like the blended wing body (BWB) aircraft. The main objectives of ACFA are the design of a new ultra efficient 450 passenger BWB type aircr...
