On a boundary value problem of a singular discrete time system with a singular pencil
Ioannis K. Dassios
In this article, we study a boundary value problem of a class of singular linear discrete time systems whose coefficients are non-square constant matrices or square with a matrix p…
A mathematical model for plasticity and damage: A discrete calculus formulation
Ioannis Dassios, Andrey Jivkov, Andrew Abu-Muharib +1
In this article we propose a discrete lattice model to simulate the elastic, plastic and failure behaviour of isotropic materials. Focus is given on the mathematical derivation of…
On the Unity Row Summation and Real Valued Nature of the Matrix
Ioannis Dassios, Paul Cuffe, Andrew Keane
Electrical power system calculations rely heavily on the matrix, which is the Laplacian matrix of the network under study, weighted by the complex-valued admittance of ea…
A Preconditioner for a Primal-Dual Newton Conjugate Gradients Method for Compressed Sensing Problems
Ioannis Dassios, Kimon Fountoulakis, Jacek Gondzio
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…
