Moving straight to the target

Valvulogenesis: the moving target.

Valvulogenesis is an extremely complex process by which a fragile gelatinous matrix is populated and remodelled during embryonic development into thin fibrous leaflets capable of maintaining unidirectional flow over a lifetime. This process occurs during exposure to constantly changing haemodynamic forces, with a success rate of approximately 99%. Defective valvulogenesis results in impaired ca...

Information security: The moving target

Information security has evolved from addressing minor and harmless security breaches to managing those with a huge impact on organisations’ economic growth. This paper investigates the evolution of information security; where it came from, where it is today and the direction in which it is moving. It is argued that information security is not about looking at the past in anger of an attack onc...

Quadrotor UAV Guidence For Ground Moving Target Tracking

The studies in aerial vehicles modeling and control have been increased rapidly recently. In this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) is considered. In this paper the UAV plays the role of a virtual leader for the UGVs. The system consists of a vision- based target detection algorithm that uses the ...

Moving target D* Lite

Incremental search algorithms, such as Generalized FringeRetrieving A* and D* Lite, reuse search trees from previous searches to speed up the current search and thus often find cost-minimal paths for series of similar search problems faster than by solving each search problem from scratch. However, existing incremental search algorithms have limitations. For example, D* Lite is slow on moving t...
