WebThe Driver and Vehicle Standards Agency (DVSA) is an executive agency, sponsored by the Department for Transport. It improves road safety by setting standards for driving and motorcycling, and making sure that drivers, vehicle operators and MOT garages follow roadworthiness standards. WebDec 1, 2024 · In this theory, the optimum parameters of DVAs for maximizing the damping effect can be determined using two special points on frequency response curves; therefore, the theory is currently called the fixed-points theory. The details of this method are presented in the text book written by Den Hartog [1]. flowsplit
