    • Analytical Modeling of Transient Electromigration Stress based on Boundary Reflections 

      Al Shohel M.A., Chhabria V.A., Evmorfopoulos N., Sapatnekar S.S. (2021)
      Traditional methods that test for electromigration (EM) failure in multisegment interconnects, over the lifespan of an IC, are based on the use of the Blech criterion, followed by Black’s equation. Such methods analyze ...

    • Circular tunnel in a gradient elastoplastic rock mass 

      Efremidis G., Chen H., Tsagrakis I., Aifantis E.C., Qi C. (2020)
      This paper attempts to study the mechanical behavior of an elastoplastic rock mass around an underground circular excavation by using gradient theory. The problem (in plane conditions) is reduced to that of a circular hole ...

    • Optimal sensor placement for reliable virtual sensing using modal expansion and information theory 

      Ercan T., Papadimitriou C. (2021)
      A framework for optimal sensor placement (OSP) for virtual sensing using the modal expansion technique and taking into account uncertainties is presented based on information and utility theory. The framework is developed ...

    • Outage Probability of a Multisensor Mixed UOWC-FSO Setup 

      Christopoulou C., Sandalidis H.G., Ansari I.S. (2019)
      The performance of a network consisting of several underwater sensors communicating with a terrestrial destination is studied for the first time in terms of the outage probability. In the scenario under consideration, K ...

    • A simple statistical model for turbulence-induced fading in free-space optical systems 

      Chatzidiamantis, N. D.; Sandalidis, H. G.; Karagiannidis, G. K.; Matthaiou, M. (2010)
      In this paper, we propose the Inverse Gaussian (IG) distribution, as a less complex alternative to Log-normal (LN), to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence ...

    • Wireless network coding with partial overhearing information 

      Paschos, G. S.; Fragiadakis, C.; Georgiadis, L.; Tassiulas, L. (2013)
      We study an 1-hop broadcast channel with two receivers. Due to overhearing channels, the receivers have side information which can be leveraged by interflow network coding techniques to provide throughput increase. In this ...
