We describe the main building blocks of a generic automated package for the calculation of Feynman diagrams. These blocks include the generation and creation of a model file, the graph generation, the symbolic calculation at an intermediate level of the Dirac and tensor algebra, implementation of the loop integrals, the generation of the matrix elements or(More)
— Hardware architecture of Rate-Distortion Optimization (RDO) is proposed, which is dedicated to H.264 block size decision of 1080 HD. To achieve high encoding efficiency of H.264, RDO for block size decision is indispensable but suffers from enormous computational costs since distortion and the number of coded bits can be determined only after completing(More)
Automatic calculation of 1-loop diagrams in the electroweak theory with gauge parameter independence checks Abstract A general non-linear gauge condition is implemented into GRACE, an automated system for the calculation of physical processes in high-energy physics. These new gauge-fixing conditions are used as a very efficient means to check the results of(More)
