WebDec 21, 2024 · The article presents the standard method of the evaluation of car drivers’ psychomotor reaction times. A characteristic feature of this method is the ability to conduct tests using real vehicles equipped with mobile measuring apparatus. Measurements are carried out on people whose task is to initiate specific maneuvers (such as: a braking or … Webunder which the gas combusts, and the energy release from the reaction zone maintains the strength of the shock. This is in contrast to a flame, or deflagrative combustion, in which thermal and species trans-port processes dominate. A detonation may form via direct initiation or deflagration-to-detonation transition (DDT). The blackthorne haunted house
