The aim of this paper is to explain the relationship between air pollutant-emissions and waiting times whilst aircrafts queue to access London Heathrow (LHR) runways. The approach to this problem is to develop a discrete-event simulation that describes the current landing and take-off operations, aircraft inter-arrivals and inter-departures, runway utilisation, and average waiting times for the...

We have developed a method for the detection of both generic flight neighbouring aircrafts and those on a collision course. Our approach employs a sliding window linear Support Vector Machine (SVM) classifier with a Histogram of Oriented Gradients (HOG) feature representation. An extension of this approach to the spatio-temporal domain is also considered and we demonstrate its advantage for the...

Aircraft automatic detection from very high-resolution (VHR) images plays an important role in a wide variety of applications. This paper proposes a novel detector for aircraft detection from very high-resolution (VHR) remote sensing images. To accurately distinguish aircrafts from background, a circle-frequency filter (CF-filter) is used to extract the candidate locations of aircrafts from a l...

This paper focuses on the aircraft landing optimization problem where both the landing routes and the landing order of aircrafts should be optimized to minimize an occupancy time of airport, and proposes its optimization method which is robust to dynamical situations such as weather condition change and other aircrafts’ landing routes change. As a difficulty of this optimization problem, approp...

The scheduling efficiency of carrier-based aircrafts on flight deck is an important factor improving the sortie rates aircrafts. Based key process deck-based aircrafts, main research directions in field are summarized, which path planning and collision detection integrated method aircraft fleets, coordinated strategies Then, researches dispatch system introduced. progress shortcomings existing ...

This paper aims to show, that the preforming process of parts made of Carbon Fiber Reiforced Thermoplastics (CFRTP) can be improved, when using several technologies like near-net shape cut-piece generation with forming simulation, automated cut-piece detection, robotic gripping and laydown of fabrics. Thereby the authors of this paper want to contribute to the increase of CFRTP applications in ...

General aviation rapidly becomes blossom with the growing economy. However, the complex flying environment and the flexibility for general aircrafts cause more difficulty to ensure the flying safety and efficiency. Hence it is vital to plan path for aircrafts to keep them away from threat and reduce fuel consumption. In this paper, we propose a path planning method based on an improved Nondomin...

Unlike old-fashioned aircrafts that almost did not have avionics systems, up to date aircrafts have numerous avionics systems. Nearly all new aircrafts have devices for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system in addition to communication and monitoring systems. All of these devices employ embedded computer systems with growin...

Delay Tolerant Network suffers from lack of resources and disconnected contact nature. In DTN, all possible methods are used to transmit data including the physical transportations means. Aircrafts in commercial routes have been proposed to carry data from ground users along their flying routes. Delivery probability is compared when using aircrafts, buses and ferries. Results show that aircraft...
