Total and/or differential cross sections for single electron capture, single ionization, double ionization, and electron capture plus ionization have been measured for collisions of protons at energies of 6, 12.5, 25, and 50 keV with C2H2 molecules. Two-dimensional position-sensitive detectors were used for both the projectile and recoil particle detection. Coincidences between the recoil time-...

Heavy ion collisions have been investigated since the 1960's. The current series of experiments at the RHIC facility at Brookhaven began in 2000. Each pair of colliding nuclei will yield from several hundred to over 1000 particles, and a typical experimental run will involve tens of thousands of collisions. The current generation of detectors identifies and measures the momentum of the majority...

A strangeness and isospin asymmetry including statistical bootstrap model analysis of the multiparticle system produced in the Pb + Pb collision at 158 AGeV at CERN is presented. It is concluded that this interaction process has not crossed the deconfinenent line. Direct comparisons with the results of similar analyses pertaining to nucleus-nucleus and p− p̄ collisions at CERN are made. The over...

To solve the RFID tag collision problem, a new anti-collision algorithm is proposed by improving the binary tree search algorithm. Through improving the requesting establishment, this algorithm reduces the probability of collision bits and the number of tags requiring collision detection time by using the even number bits for impact identification. The simulation results show that compared with...

Unmanned aerial vehicles (UAVs) are being utilized in a growing variety of military and civil situations. One major issue in situations that require multiple UAVs to share the same air space is collision avoidance. A successful collision avoidance system should allow a UAV to prevent all collisions without greatly impacting flight path efficiency. This study reviews literature centered on colli...

Combined with lock algorithm, retreat algorithm and multithreaded processing thoughts; it puts forward an anti-collision algorithm based on multi-threaded RFID lock position. RFID reader sends a quad command, RFID tag response the information of collision position, reduce the amount of data transmission; Fused with lock and multi-status thoughts, the algorithm checks the lock position of card n...

This paper describes an efficient approach to (self) collision detection and distance computations for complex articulated mechanisms such as molecular chains. The proposed algorithm called BioCD is particularly designed for samplingbased motion planning on molecular models described by long kinematic chains possibly including cycles. The algorithm considers that the kinematic chain is structur...

We present data structures and algorithms for dynamic collision detection in virtual reality (VR) applications. The methods are applicable to all general polygonal models. They combine the advantages of collision detection using bounding volume (BV) hierarchies with the ability to compute dynamic collision detection results. The results are used as input for further simulations, e.g. contact or...

The safety of ships in regards to collisions and groundings, as well as the navigational and structural aspects of ships, has been improved and developed up to this day by technical, administrative and nautical parties. The damage resulting from collisions could be reduced through several techniques such as designing appropriate hull structures, ensuring tightness of cargo tanks as well as obse...
