      Adaptive packet scheduling over a wireless channel under constrained jamming 

      Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2017)
      In this work we consider the communication over a wireless link, between a sender and a receiver, being disrupted by a jammer. The objective of the sender is to transmit as much data as possible to the receiver in the most ...

      Developing and investigating a pure Monte-Carlo module for transient neutron transport analysis 

      Mylonakis, A. G.; Varvayanni, M.; Grigoriadis, D. G. E.; Catsaros, N. (2017)
      In the field of computational reactor physics, Monte-Carlo methodology is extensively used in the analysis of static problems while the transient behavior of the reactor core is mostly analyzed using deterministic algorithms. ...

      Efficient gossip and robust distributed computation 

      Georgiou, Chryssis; Kowalski, D. R.; Shvartsman, A. A. (2003)
      This paper presents an efficient deterministic gossip algorithm for p synchronous, crash-prone, message-passing processors. The algorithm has time complexity T = O(log2 p) and message complexity M = O(p1+ε), for any ε > ...

      Online parallel scheduling of non-uniform tasks: Trading failures for energy 

      Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2015)
      Consider a system in which tasks of different execution times arrive continuously and have to be executed by a set of machines that are prone to crashes and restarts. In this paper we model and study the impact of parallelism ...

      Online parallel scheduling of non-uniform tasks: Trading failures for energy 

      Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2013)
      Consider a system in which tasks of different execution times arrive continuously and have to be executed by a set of processors that are prone to crashes and restarts. In this paper we model and study the impact of ...
