      ADVISE – A framework for evaluating cloud service elasticity behavior 

      Copil, G.; Trihinas, Demetris; Truong, H. -L; Moldovan, D.; Pallis, George C.; Dustdar, S.; Dikaiakos, Marios D. (2014)
      Complex cloud services rely on different elasticity control processes to deal with dynamic requirement changes and workloads. However, enforcing an elasticity control process to a cloud service does not always lead to an ...

      Control-driven coordination programming in shared dataspace 

      Papadopoulos, George Angelos; Arbab, Farhad (1997)
      This paper argues for an alternative way of designing coordination models for parallel and distributed environments based on a complete symmetry between and decoupling of producers and consumers, as well as a clear distinction ...

      Numerical simulation of die filling in semisolid metal processing 

      Bardinet, F.; Alexandrou, Andreas N.; Loue, Willem (Affiliation: WPI, Worcester, United StatesCorrespondence Address: Bardinet, FrancoisWPI, Worcester, United States, 1997)
      Semisolid Metal Processing offers distinct advantages over other near-net-shape technologies, such as a more homogeneous microstructure, less porosity and thus excellent mechanical properties. A perfect control of die ...

      A sufficient condition for decentralized non-cooperative stochastic differential games and relations to mean field games 

      Charalambous, Charalambos D. (Institute of Electrical and Electronics Engineers Inc., 2015)
      In this paper we use martingale techniques to derive a sufficient condition for existence of decentralized strategies in non-cooperative stochastic differential games. The sufficient condition is given by decentralized ...
