Collision prediction using MKtrees

Franquesa Niubó, Marta; Brunet Crosa, Pere (2004)
Text en actes de congrés
Accés restringit per política de l'editorial

K dimensional tree data structure(Multiresolution Kdtree, MKtree) is introduced. In a complex scene containing a high number of individual objects, the MKtree represents a hierarchical subdivision of the scene objects that ...

Collision prediction using MKtrees: broad phase and refinement levels of the narrow phase

Franquesa Niubó, Marta; Brunet Crosa, Pere (2003-10)
Report de recerca
Accés obert

In this paper, the collision prediction between polyhedra under screw motions and a static scene using a new $ dimensional tree data structure ({emph Multiresolution Kdtree, MKtree}) is introduced. In a complex ...

Collision queries: models and algorithms

Franquesa Niubó, Marta; Brunet Crosa, Pere (2003-10)
Report de recerca
Accés obert

In this paper, a review of models and algorithms that are conceived to solve the collision queries problem is presented. Here, the type of query in proximity and collision computations is stated. The phases to solve the ...

Collision risk assessment for ships’ routeing waters: An information entropy approach with Automatic Identification System (AIS) data

Feng, Hongxiang; Grifoll Colls, Manel; Yang, Zhongzhen; Zheng, Pengjun (2022-06-01)

The ship's routing was adopted to organise marine traffic flow and reduce the risk of collision between ships in crowded waters. With the expansion of the world's fleet, ship traffic in shipping bottleneck and chokepoint ...

Collision-balancing frequency hopping in single-hop mobile ad hoc networks

Tanbourgi, Ralph; Pujol i Molist, Xevi; Jondral, Friedrich K. (Institute of Electrical and Electronics Engineers (IEEE), 2012)

We consider a single-hop frequency hopping (FH) mobile ad hoc network (MANET). To increase throughput orthogonal FH (O-FH) with hop-synchronous hopping can be used, thereby allowing collision-free transmissions under certain ...
