Collision detection is a fundamental geometric tool for samplingbased motion planners. On the contrary, collision prediction for the scenarios that obstacle’s motion is unknown is still in its infancy. This paper proposes a new approach to predict collision by assuming that obstacles are adversarial. Our new tool advances collision prediction beyond the translational and disc robots; arbitrary ...

Interactive bodies collision detection and elimination is one of the most popular task nowadays. Collisions can be detected in different ways. Collision search using space voxelization is one of the most fast. This paper describes improved voxel model that covers only area of collision interest and quickly eliminates collisions. This new method can be useful in real time collision processing of...

We study characteristic schemes for a model problem for the Fermi pencil beam equation. The objective is twofold: (i) To design eecient and accurate numerical schemes based on the principle of solving a particle transport problem, exactly, on each collision free spatial segment combined with a projection on each collision site, from a pre collision angle and energy coordinates (AE) to a post co...

In this paper, we propose an approach which combines hierarchical structures and particle systems for self-collision detection occurring in a deformable object. Numerous algorithms for collision detection have been proposed in computer graphics applications. Our algorithm exploits the efficiency of hierarchical structures to deal with many polygons, and particle systems because they can be used...

In this study, an energetic hard-sphere ion-neutral collision model was proposed to bridge-link ion collision cross section (CCS) with the image current collected from a high-resolution Fourier transform ion cyclotron resonance (FT-ICR) cell. By investigating the nonlinear effects induced by high-order electric fields and image charge forces, the energetic hard-sphere collision model was valida...

An effective collision avoidance system for unmanned aircraft will enable them to fly in civil airspace and greatly expand their applications. One promising approach is to model aircraft collision avoidance as a partially observable Markov decision process (POMDP) and automatically generate the threat resolution logic for the collision avoidance system by solving the POMDP model. However, exist...

In this paper, the authors introduced a new approach to find the optimal collision avoidance maneuver considering multi threatening objects within short period, while minimizing the fuel consumption and satisfying the acceptable collision probability. A preliminary effort in applying a genetic algorithm (GA) to those kinds of problems has also been demonstrated through a simulation study with a...

The Reader Collision Problem (RCP) is a bottle-neck decreasing the reading efficiency in multiplereader RFID systems. This paper proposed a novel anti-collision protocol – DRA (Distributed Reservation-based Anti-collision) protocol to solve the RCP in multiple-reader RFID systems. Temporal Cluster Headers (TCHs) are dynamically selected among the potentially interfered readers in DRA protocol. ...

[Abstract]: With the rapid development of space technology, more and more spacecraft have been launched into space, at the same time, the number of space debris increased dramatically, the probability of collision between space debris and spacecraft arise accordingly. To evaluate the collision effect, some evaluation methods should be studied. The paper introduces some evaluation methods accord...
