1International Regulations for Preventing Collisions at Sea — The International Regulations for Preventing Collisions at Sea 1972 (COLREGS) are published by the International Maritime Organization (IMO), and set out, inter alia, the rules of the road or navigation rules to be followed by ships and other… …
2Threshold displacement energy — The threshold displacement energy Td is the minimum kinetic energy that an atom in a solid needs to be permanently displaced from its lattice site to a defect position. It is also known as displacement threshold energy or just displacement energy …
3Collision cascade — A classical molecular dynamics computer simulation of a collision cascade in Au induced by a 10 keV Au self recoil. This is a typical case of a collision cascade in the heat spike regime. Each small sphere illustrates the position of an atom, in… …
