In applications ranging from video reception to telecommunications and packet communication to aircraft control, tasks enter periodically and have xed response time constraints, but missing a deadline is acceptable, provided most deadlines are met. We call such tasks \occasionally skippable". We look at the problem of uniprocessor scheduling of occasionally skippable periodic tasks in an enviro...

In the present paper, an efficient method for three dimensional aircraft pattern recognition is introduced. In this method, a set of simple area based features extracted from silhouette of aerial vehicles are used to recognize an aircraft type from its optical or infrared images taken by a CCD camera or a FLIR sensor. These images can be taken from any direction and distance relative to the fly...

Optimizing naval aircraft deck sortie scheduling is important for improving the efficiency of groups. It also an link in realizing automated carriers. Firstly, a single-aircraft surface transit path library was constructed. This paper used improved A* algorithm and optimal control planning to construct between parking position take-off position, or warmable non-warmable positions. Secondly, mat...

Due to the large increase in the density of aircraft arrivals at airports in recent years, it has become important to optimize the scheduling of aircraft landings in order to reduce wait time, improve airport efficiency, and minimize fuel consumption while maintaining safety. As the density of aircraft arrivals increases, however, so too does the complexity of trajectory planning and generation...
