The number of blocks with a given defect group
(London Mathematical Society, 1997)Given a Psubgroup P of a finite group G, we express the number of Pblocks of G with defect group P as the /?rank of a symmetric integer matrix indexed by the N (P) / Pconjugacy classes in PC(P)/P. We obtain ...

Numerical implementation of absorbing and injecting boundary conditions for the timedependent Schrödinger equation
(American Physical Society, 1995)A method is described that enables the absorption and injection of wave functions at the boundaries of a region in a numerical solution to the timedependent Schrödinger equation. A number of results corresponding to one ... 
A numerical method for stability windows and unstable rootlocus calculation for linear fractional timedelay systems
(Elsevier, 20120814)This paper aims to provide a numerical algorithm able to locate all unstable poles, and therefore the characterization of the stability as a function of the delay, for a class of linear fractionalorder neutral systems ... 
Numerical methods and software tools for simulation, design, and resonant mode analysis of radio frequency birdcage coils used in MRI
(WileyLiss Inc., 2015)Design of magnetic resonance imaging (MRI) radiofrequency (RF) coils using lumped circuit modeling based techniques begins to fail at high frequencies, and therefore more accurate models based on the electromagnetic field ...
