qasr or hasr (restriction) is one of the techniques of semantics that can be used in different ways. most of former thinkers believed that despite differences that exist in how these methods convey meaning to readers or audience, they function similarly. this research is a descriptive-analytical study of methods of qasr and tries to elaborate on the fundamental differences among these methods. ...

(Received) We investigate an application of the method of fundamental solutions (MFS) to heat conduction in two-dimensional bodies, where the thermal diffusivity is piecewise constant. We extend the MFS proposed in [15] for one-dimensional heat ...

The purpose of this thesis is to extend the range of application of the method fundamental solutions (MFS) to solve direct and inverse geometric problems associated with twoor three-dimensional Helmholtz-type equations. Inverse problems have become more and more important in various fields of sicence and technology, and have certainly been one of the fastest growing areas in applied mathematics...

This chapter describes an application of the recently proposed Modified Method of Fundamental Solutions (MMFS) to the potential flow problems. The solution in two dimensional Cartesian coordinates is represented in terms of the fundamental solution of the Laplace equation together with the first order polynomial augmentation. The collocation is used for determination of the expansion coefficien...

The method of fundamental solutions (MFS) is a numerical for solving boundary value problems involving linear partial differential equations. It well-known that it can be very effective assuming regularity the domain and conditions. main drawback MFS matrices involved are typically ill-conditioned this may prevent from achieving high accuracy. In work, we propose new algorithm to remove ill-con...
