Capacity of Binary State Symmetric Channel with and without feedback and transmission cost
(Institute of Electrical and Electronics Engineers Inc., 2015)We consider a unit memory channel, called Binary State Symmetric Channel (BSSC), in which the channel state is the modulo2 addition of the current channel input and the previous channel output. We derive closed form ...

A CaseBased Electronic Learning Environment for Preservice Teacher Education
(1998)This study took place within a teacher education program at a large Midwestern university with vast field observation placements around the state and the world. The purpose was to discover whether preservice teacher ...

Computer assisted formative assessment: supporting students to become more reflective Learners
(University of Cyprus, 2007)eAssessment is being advocated in the UK as our way of introducing a more personalised learning agenda throughout the Higher Education sector. This paper discusses the findings from two projects where formative eassessment ...

Article
Design of strictly positive real systems using constant output feedback
(1999)In this paper, the authors present a linear matrix inequality (LMI) approach to the strictly positive real (SPR) synthesis problem: find an output feedback K such that the closedloop system T(s) is SPR. The authors establish ...

Feedback control over packet dropping network links
(2007)This paper studies stabilization schemes for a discretetime control systems in which the feedback loop includes a network link that may suffer packet drops. We model the packet dropping network link as an erasure channel ...

Feedback does not increase the capacity of compound channels with additive noise
(Institute of Electrical and Electronics Engineers Inc., 2016)A discrete compound channel with memory is considered, where no stationarity, ergodicity or information stability is required, and where the uncertainty set can be arbitrary. When the discrete noise is additive but otherwise ...

Information structures of capacity achieving distribution for channels with memory and feedback
(Institute of Electrical and Electronics Engineers Inc., 2016)The information structures of the optimal channel input distributions P[0,n] t {PAiAi1,Bi1 : i = 0,1.,n}, which correspond to the extremum problem of feedback capacity equation are identified, for any class of channel ...

Article
Information Transfer of Control Strategies: Dualities of Stochastic Optimal Control Theory and Feedback Capacity of Information Theory
(2017)The controlcoding capacity of stochastic control systems is introduced, and its operational meaning is established using randomized control strategies, which simultaneously control output processes encode information, and ...

Modeling and control design for a computercontrolled brake system
(1997)The brake subsystem is one of the most significant parts of a vehicle with respect to safety. A computercontrolled brake system has the capability of acting faster than the human driver during emergencies, and therefore ...

On the role of feedback in the design of perfectly reconstructing equalizers
(2007)In this paper we consider the transmission of discrete data via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unrestricted behavior. We are ...

Article
Performance analysis for a changepoint problem
(1999)Nonlinear stochastic differential equations are used to model a version of the changepoint problem. State estimates of the minimum meansquareerrortype are used in likelihoodratio tests to detect the time of change. ...

Remarks on the explicit solutions for nonlinear partially observable stochastic control problems and relations to H∞ or robust control
(IEEE, 1995)Partially observable stochastic and H∞ control problems are considered. The dynamics include nonlinearities which are the gradient of some potential function in addition to linear terms, the observations are linear, and ...

Article
A robust adaptive nonlinear control design
(1996)An adaptive control design procedure for a class of nonlinear systems with both parametric uncertainty and unknown nonlinearities is presented. The unknown nonlinearities lie within some 'bounding functions', which are ...
