Comparison of two methods for the computation of singular solutions in elliptic problems
Georgiou, Georgios C.; Boudouvis, Andreas G.; Poullikkas, A. (1997)We compare two numerical methods for the solution of elliptic problems with boundary singularities. The first is the integrated singular basis function method (ISBFM), a finiteelement method in which the solution is ...

Lost in the national labyrinths of bureaucracy: The case of renewable energy governance in Cyprus
Fokaides, P. A.; Poullikkas, A.; Christofides, Constantinos (2013)In July 2011, Cyprus experienced an abrupt disruption of power supply as a result of an explosion that happened near the biggest conventional power station of the island, which destroyed about 60 % of the its power generating ...

The method of fundamental solutions for inhomogeneous elliptic problems
Poullikkas, A.; Karageorghis, Andreas; Georgiou, Georgios C. (1998)We investigate the use of the Method of Fundamental Solutions (MFS) for solving inhomogeneous harmonic and biharmonic problems. These are transformed to homogeneous problems by subtracting a particular solution of the ...

The method of fundamental solutions for Signorini problems
Poullikkas, A.; Karageorghis, Andreas; Georgiou, Georgios C. (1998)We investigate the use of the method of fundamental solutions (MFS) for the numerical solution of Signorini boundary value problems. The MFS is an ideal candidate for solving such problems because inequality conditions ...

The Method of Fundamental Solutions for Stokes Flows with a Free Surface
Poullikkas, A.; Karageorghis, Andreas; Georgiou, Georgios C.; Ascough, J. (1998)We investigate the use of the Method of Fundamental Solutions (MFS) for solving Stokes flow problems with a free surface. We apply the method to the creeping planar Newtonian extrudateswell problem and study the effect ...

The numerical solution of threedimensional Signorini problems with the method of fundamental solutions
Poullikkas, A.; Karageorghis, Andreas; Georgiou, Georgios C. (2001)The method of fundamental solutions (MFS) is formulated for threedimensional Signorini boundaryvalue problems. The method is tested on a threedimensional electropainting problem related to the coating of vehicle roofs. ...

Stress intensity factor computation using the method of fundamental solutions
Karageorghis, Andreas; Poullikkas, A.; Berger, J. R. (2006)In this paper, we study the application of the method of fundamental solutions to the computation of stress intensity factors in linear elastic fracture mechanics. The displacements are approximated by linear combinations ...
