      A Perfect Reconstruction Paradigm for Digital Communication 

      Voulgaris, P. G.; Hadjicostis, Christoforos N.; Touri, R. (2003)
      In this paper we present a deterministic worst-case framework for reconstruction of discrete data transmissions through dispersive communication channels. This framework can be explored based on robust control ideas and ...

      Probabilistic detection of FSM single state-transition faults based on state occupancy measurements 

      Hadjicostis, Christoforos N. (2005)
      This note discusses a probabilistic methodology for detecting single permanent or transient functional changes in the state-transition mechanism of a deterministic finite-state machine (FSM). The associated probabilistic ...

      Robust control over uncertain communication channels 

      Charalambous, Charalambos D.; Farhadi, A.; Denic, S.; Rezaei, F. (2005)
      In this paper, the mathematical framework for studying robust control over uncertain communication channels is introduced. The theory is developed by generalizing the classical information theoretic measures of information ...

      Stochastic H∞-control of nonlinear discrete-time partially observable systems and dissipation inequalities 

      Charalambous, Charalambos D.; Djouadi, S. M.; Ahmed, N. U. (2002)
      This paper employs an action functional approach to formulate partially observable nonlinear discrete-time stochastic minimax games. The maximizing players of the games are stochastic square summable disturbances, while ...

      Stochastic optimal control of discrete-time systems subject to conditional distribution uncertainty 

      Charalambous, Charalambos D.; Tzortzis, I.; Rezaei, F. (2011)
      The aim of this paper is to address optimality of control strategies for stochastic discrete time control systems subject to conditional distribution uncertainty. This type of uncertainty is motivated from the fact that ...

      Synchronization-based fault detection in discrete event systems 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2004)
      In this paper we study fault detection in systems that can be modeled as finite state machines (FSMs). We aim at detecting faults that manifest themselves as permanent changes in the next-state transition functionality of ...

      Traffic Density Control for Automated Highway Systems 

      Chien, C. -C; Zhang, Y.; Ioannou, Petros A. (1997)
      Traffic flow instabilities such as traffic congestion are often caused by ad hoc and inappropriate speeds and headways that humans choose when they operate their vehicles. In an automated highway system (AHS) environment, ...
