[1] It was established under this name in 1948 [ 2 ] as a non-profit trade organization [ 3 ] in order to promote the sport and organize its players via ...
Binary collision approximation. In condensed-matter physics, the binary collision approximation ( BCA) is a heuristic used to more efficiently simulate the penetration depth and defect production by energetic ions (with kinetic energies in the kilo-electronvolt ( keV) range or higher) in solids. In the method, the ion is approximated to travel ...
Optical discs. In computing, the burst cutting area (BCA) or narrow burst cutting area (NBCA) is the circular area near the center of a DVD, HD DVD or Blu-ray Disc, where a barcode can be written for additional information such as ID codes, manufacturing information, and serial numbers. The BCA can be written during mastering and will be common ...
