  • Cuffe, Paul; Dassios, Ioannis K.; Keane, Andrew (IEEE Computer Society, 2016)
    Abstract—Loss minimizing generator dispatch profiles for power systems are usually derived using optimization techniques. However, some authors have noted that a system’s KGL matrix can be used to analytically determine ...
  • Dassios, Ioannis K.; Zimbidis, Alexandros; Kontzalis, Charalambos (Springer, 2014)
    This paper extends the classical Samuelson multiplier–accelerator model for national economy. Actually, this new modeling structure removes the basic shortcoming of the original model producing stable business cycles when ...
  • Dassios, Ioannis K.; Cuffe, Paul; Keane, Andrew (2015)
    Electrical power system calculations rely heavily on the Y_{bus} matrix, which is the Laplacian matrix of the network under study, weighted by the complex-valued admittance of each branch. It is often useful to partition ...
  • Dassios, Ioannis K. (Elsevier, 2018)
    In this article, we focus on a generalized problem of linear non-autonomous fractional nabla difference equations. Firstly, we define the equations and describe how this family of problems covers other linear fractional ...
  • Dassios, Ioannis K.; Fountoulakis, Kimon; Gondzio, Jacek (Society for Industrial and Applied Mathematics, 2016)
    In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend the primal-dual Newton Conjugate Gradients ...
  • O'Brien, Joseph D.; Dassios, Ioannis K.; Gleeson, James P. (IOP Publishing, 2019)
    A model for the spreading of online information or ‘memes’ on multiplex networks is introduced and analyzed using branching-process methods. The model generalizes that of (Gleeson et al 2016 Phys. Rev.X) in two ways. ...
