Abstract : The research has proceeded along three distinct lines. (1) The behavior of closed loop control systems with randomly timed sampling within the feedback loop. Random sampling in a feedback context occurs in systems with a controller consisting of a time shared computer, control systems with imperfect samplers, and remote control whose feedback function is performed at a distance via a pulse coded transmission link. (2) Recovery of data from samples taken at random intervals, including time-multiplexed communication systems and real-time digital handling of data. (3) The applicability of martingale theory to stochastic point processes. In particular, the Doob decomposition for continuous-parameter supermartingales which is crucial to the modern theory of detection and estimation of stochastic signals corrupted by additive white noise.
