      An Algorithm for Global Maximization of Secrecy Rates in Gaussian MIMO Wiretap Channels 

      Loyka, S.; Charalambous, Charalambos D. (2015)
      Optimal signaling for secrecy rate maximization in Gaussian MIMO wiretap channels is considered. While this channel has attracted a significant attention recently and a number of results have been obtained, including the ...

      Multimodal Dynamic Freight Load Balancing 

      Abadi, A.; Ioannou, Petros A.; Dessouky, M. M. (2016)
      The urban traffic network has temporal and spatial characteristics whose changing conditions have often unpredictable effects on the flow of loads that include passengers and freight. As a result, the current traffic network ...

      Nonlinear estimation for a class of systems 

      Socratous, Y.; Rezaei, F.; Charalambous, Charalambos D. (2009)
      This paper considers nonlinear estimation problems for classes of models, and employs relative entropy to describe the uncertainty classes. Two optimization problems are formulated on general Banach spaces, and their ...

      A scalable iterative convex design for nonlinear systems 

      Baldi, S.; Ioannou, Petros A.; Kosmatopoulos, E. B. (2012)
      A recently developed control scheme for approximately optimal control of nonlinear systems is the so-called Convex Control Design (ConvCD) methodology, that transforms the control problem of generic nonlinear systems into ...
