The prediction of collisions amongst N rigid objects may be reduced to a series of computations of the time to first contact for all pairs of objects. Simple enclosing bounds and hierarchical partitions of the space-time domain are often used to avoid testing object-pairs that clearly will not collide.

Ergonomics in Design: The Quarterly of Human Factors Applications, 2000
On June 25, 1997, the Russian supply spacecraft Progress 234 collided with the Mir space station, rupturing Mir's pressure hull, throwing it into an uncontrolled attitude drift, and nearly forcing evacuation of the station. Like many high-profile accidents, this collision was the consequence of a chain of events leading to the final piloting errors ...

Scientific American, 2012
The article discusses controversial research that suggests individuals who suffer repeated concussions, such as football players, may be at risk for a distinct type of amyotrophic lateral sclerosis (ALS), known as Lou Gehrig's disease. Topics include a brief profile of former U.S.

Traces of collisions within collisions
Science, 2015Lunar Formation The Moon is widely accepted to have been created by the collision of a Mars-sized body with Earth. However, information about exactly when this event occurred is still welcome. To find out more, Bottke et al. compared models and the meteorite record with estimates of impact heating.

Collision group and renormalization of the Boltzmann collision integral
Physical Review E, 2002On the basis of a recently discovered collision group [V. L. Saveliev, in Rarefied Gas Dynamics: 22nd International Symposium, edited by T. J. Bartel and M. Gallis, AIP Conf. Proc. No. 585 (AIP, Melville, NY, 2001), p. 101], the Boltzmann collision integral is exactly rewritten in two parts.

IEEE Internet Computing, 2016
The Internet was designed to function in a location-agnostic fashion, but there will always be legal considerations and jurisdictions trying to tether the Web to geographical rules and constraints. How will geography and intellectual property affect future Internet practices?

Visually guided collision avoidance and collision achievement
Trends in Cognitive Sciences, 2000To survive on today's highways, a driver must have highly developed skills in visually guided collision avoidance. To play such games as cricket, tennis or baseball demands accurate, precise and reliable collision achievement. This review discusses evidence that some of these tasks are performed by predicting where an object will be at some sharply ...

Imaging of collisions by laser excitation of the collision complex
SPIE Proceedings, 2003Atomic or molecular collision complexes are difficult to observe, because they have typical lifetimes of the order of picoseconds. The technique of differential optical collisions can be used in different ways to serve this purpose. We discuss here the methods allowing geometric observations for typical examples involving atomic and molecular collision

Proceedings of the 2012 ACM international conference on Interactive tabletops and surfaces, 2012
In this paper we present the design, implementation and preliminary evaluation of Re-Collision, a prototype collision reconstruction tabletop interface. Re-Collision was developed through a participatory design process involving expert users from the Calgary Police Forensics Team and Collision Reconstruction Team.

Generalized RC4 Key Collisions and Hash Collisions
2010In this paper, we discovered that RC4 can generate colliding key pairs with various hamming distances, other than those found by Matsui (with hamming distance one), and by Chen and Miyaji (with hamming distance three). We formalized RC4 colliding key pairs into two large patterns, namely, Transitional pattern and Self-Absorbing pattern, according to ...
