This work addresses the pursuit-evasion problem of capturing a Differential Drive Robot (DDR) with Dubins Car (DC) in minimum time. We model as zero-sum differential game, and using game theory, we compute time-optimal motion strategies players near end game. unveil existence three singular surfaces: an Evader’s Dispersal Surface (EDS), Transition (TS), where DDR switches its controls, Pursuer’...

This research deals with a variation of the traveling salesman problem in which the cost of a tour, during which a kinematically constrained vehicle visits a set of targets, has to be minimized. We are motivated by scenarios that include motion planning for unmanned aerial, marine, and ground vehicles, just to name a few possible application outlets. We discretize the original continuous proble...

Let M be a complete, connected, two-dimensional Riemannian manifold with nonpositive Gaussian curvature K. We say that M satisfies the unrestricted complete controllability (UCC) property for the Dubins problem if the following holds: given any (p1, v1) and (p2, v2) in TM , there exists, for every ε > 0, a curve γ in M , with geodesic curvature smaller than ε, such that γ connects p1 to p2 and,...

In order to make airplane main procedures more efficient and thus s and costs, the distribution of airplane em software will increasingly be p electronically over networks. Sinc software often implements vital func while on the other hand comm networks are in

BACKGROUND Previously reported outbreaks of norovirus gastroenteritis associated with aircraft have been limited to transmission during a single flight sector. During October 2009, an outbreak of diarrhea and vomiting occurred among different groups of flight attendants who had worked on separate flight sectors on the same airplane. We investigated the cause of the outbreak and whether the illn...

A new missile midcourse guidance algorithm is proposed in this paper. It is a combination of sampling based path planning, Dubins’ curves and classical guidance laws. Moreover, a realistic interceptor missile model is used. It allows to anticipate the future changes of flight conditions along the trajectory, especially the loss of maneuverability at high altitude. Simulation results are present...

This research addresses the problem of allocating closely spaced targets to multiple autonomous underwater vehicles (AUV) in the presence of constant ocean currents. The main difficulty of this problem is that the non-holonomic vehicles are constrained to move along forward paths with bounded curvatures. The Dubins model is a simple but effective way to handle the kinematic characteristics of A...
