      Optimization of stochastic uncertain systems with variational norm constraints 

      Rezaei, F.; Charalambous, Charalambos D.; Ahmed, N. U. (2007)
      This paper considers optimization of stochastic uncertain systems on general abstract spaces, when the uncertainty of the system is described by a variational norm constraint. The pay-off is defined as a linear functional ...

      Optimization of Stochastic Uncertain Systems: Large Deviations and Robustness 

      Charalambous, Charalambos D.; Rezaei, F. (2003)
      This paper is concerned with an abstract formulation of stochastic uncertain control systems, in which the pay-off is described by the relative entropy between the nominal measure and the uncertain measure, while the ...

      The price of selfish routing 

      Mavronicolas, Marios; Spirakis, Paul G. (2001)
      The problem of routing in congested communication networks was studied. A noncooperative network consisting of a set of m parallel links within a game theoretic framework was considered for analysis. A collection of n ...

      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 ...

      A simple graph-theoretic model for selfish restricted scheduling 

      Elsässer, R.; Gairing, M.; Lücking, T.; Mavronicolas, Marios; Monien, Burkhard (2005)
      In this work, we introduce and study a simple, graph-theoretic model for selfish scheduling among m non-cooperative users over a collection of n machines

      Solution of the planar Newtonian stick-slip problem with the singular function boundary integral method 

      Elliotis, Miltiades C.; Georgiou, Georgios C.; Xenophontos, Christos A. (2005)
      A singular function boundary integral method (SFBIM) is proposed for solving biharmonic problems with boundary singularities. The method is applied to the Newtonian stick-slip flow problem. The streamfunction is approximated ...

      Stable theories for logic programs 

      Kakas, Antonis C.; Mancarella, P. (Publ by MIT Press, 1991)
      We define a class of theories associated to any normal logic program, called stable theories, based on a notion of stable negative hypotheses. This stability of hypotheses is motivated directly from the intuitive understanding ...

      Strength of counting networks 

      Busch, Costas; Mavronicolas, Marios (1996)
      This paper shows that any counting network, made up of balancers whose fan-in and fan-out vary arbitrarily, is, indeed, strong enough to simultaneously support both Fetch&Increment and Fetch&Decrement operations, once each ...

      Subsampling the distribution of diverging statistics with applications to finance 

      Bertail, Patrice; Haefke, C.; Politis, Dimitris Nicolas; White, H. (2004)
      In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known or unknown rates when the underlying time series is strictly stationary and strong mixing. Based on our results ...

      TDM- vs. FDM- based data-item scheduling in wireless broadcast systems with user retrials 

      Vlajic, N.; Charalambous, Charalambos D.; Makrakis, D. (2003)
      In the previous research works on wireless data broadcast, time-division-multiplex (TDM) based data-item scheduling has been exclusively studied, while no mention or clear evidence against frequency-division-multiplex, ...
