This paper studies the effects of stochastic time delays on automatic control systems which uses communication networks. We assume a linear process to be controlled and known delay probability distributions.The contribution of this paper is to extend the theory in(Nilsson 1998) to delays that may be longer than one sample period.Using a quadratic cost we find the optimal full-state-information con

Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con

Världen är full av guideböcker som pekar ut vad som är sevärt. Nästan alltid är det bara det annorlunda och unika som kommer med.

Design aesthetics concerns the study of the way the features of a product are perceived by an observer. This paper shows that the moment of perception can be advantageously described with the help of results from affective neuroscience. It also shows, among other things, that the affective state of an individual is always prior to a later, slower, conscious cognition, and that it influences judgme
