      Distributed stochastic power control for time-varying long-term and short-term fading wireless networks 

      Olama, M. M.; Djouadi, S. M.; Charalambous, Charalambos D.; Sahyoun, S. (2007)
      In this paper, new time-varying wireless channel models that capture both the space and time variations of longterm and short-term fading wireless networks are developed. The proposed models are based on stochastic ...

      Dynamic demographic models and parameter identification: Simulations based on statistical data 

      Tzortzis, I.; Charalambous, Charalambos D. (Institute of Electrical and Electronics Engineers Inc., 2014)
      This paper is concerned with dynamical population models obtained from short and long-term changes in size and age composition due to demographic processes such as births, deaths, migration, etc. Both deterministic and ...

      General non-stationary models for short-term and long-term fading channels 

      Charalambous, Charalambos D.; Menemenlis, N. (Institute of Electrical and Electronics Engineers Inc., 2000)
      This paper discusses the use of stochastic differential equations to model signal envelope variations over large areas, which are subject to long-term fading effects from the transmitter to local areas, followed by short-term ...

      Probability of error bounds for failure diagnosis and classification in hidden Markov models 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2008)
      In this paper we consider a formulation of the failure diagnosis problem in stochastic systems as a maximum likelihood classification problem: a diagnoser observes the system under diagnosis online and determines which ...

      Statistical inference for multi-state reliability systems 

      Makrides, Andreas S. (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2017-01)
      Η παρούσα διατριβή θα επικεντρωθεί σε multi-state systems (MSS) τα οποία μοντελοποιούμε με τη βοήθεια των ημιμαρκοβιανών διαδικασιών. Για το λόγο αυτό, οι ημιμαρκοβιανές διαδικασίες είναι καταλληλότερες σε μελέτες αξιοπιστίας ...

      Stochastic power control for time-varying flat fading wireless channels 

      Olama, M. M.; Shajaat, S. M.; Djouadi, S. M.; Charalambous, Charalambos D. (2005)
      The performance of stochastic optimal power control of time-varying wireless short-term flat fading channels, in which the evolution of the dynamical channel is described by a stochastic state space representation, is ...

      Stochastic power control for time-varying long-term fading wireless networks 

      Olama, M. M.; Djouadi, S. M.; Charalambous, Charalambos D. (2006)
      A new time-varying (TV) long-term fading (LTF) channel model which captures both the space and time variations of wireless systems is developed. The proposed TV LTF model is based on a stochastic differential equation ...
