    • Assessing the Transition of the Romanian Power System 

      Koltsaklis N.E., Panapakidis I.P., Dagoumas A.S. (2020)
      This work presents a generic mixed integer linear programming model to determine the optimal energy and reserves scheduling of a renewable-based multi-zonal power system. In particular, through a detailed unit commitment ...
    • An efficient power constrained transmission scheme for hybrid OW/RF systems 

      Chatzidiamantis, N. D.; Georgiadis, L.; Sandalidis, H. G.; Karagiannidis, G. K. (2014)
      This paper investigates link layer transmission schemes for hybrid optical wireless (OW)/radio frequency (RF) systems with constraints on both per-link and total power consumption at the transmitter. Assuming timeslot ...
    • Finite element model validation and predictions using dynamic reduction techniques 

      Papadioti, D. C.; Papadimitriou, C. (2011)
      Finite element (FE) model updating and validation techniques are formulated as single and multi-objective optimization problems. A multi-objective optimization framework results in multiple Pareto optimal models that are ...
    • Green video delivery in LTE-based heterogeneous cellular networks 

      Galanopoulos A., Iosifidis G., Argyriou A., Tassiulas L. (2015)
      In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ...
    • Greening the Airwaves with Collaborating Mobile Network Operators 

      Koutitas G., Iosifidis G., Lannoo B., Tahon M., Verbrugge S., Ziridis P., Budzisz L., Meo M., Marsan M.A., Tassiulas L. (2016)
      Base station sharing is currently considered one of the most promising solutions for reducing the energy consumption costs of cellular networks. This paper presents a game theoretic framework for the study of such cooperative ...
    • A prosumer model based on smart home energy management and forecasting techniques 

      Koltsaklis N., Panapakidis I.P., Pozo D., Christoforidis G.C. (2021)
      This work presents an optimization framework based on mixed-integer programming techniques for a smart home’s optimal energy management. In particular, through a cost-minimization objective function, the developed approach ...
    • Use-based optimization of Spatial access methods 

      Athanasiou N., Corral A., Vassilakopoulos M., Manolopoulos Y. (2017)
      Spatial access methods have been extensively studied in the literature, during last decades. Access methods were designed for efficient processing of demanding queries and extensive comparisons between such methods have ...
