in this paper an exponentially fitted finite difference method is presented for solving singularly perturbed two-point boundary value problems with the boundary layer. a fitting factor is introduced and the model equation is discretized by a finite difference scheme on an uniform mesh. thomas algorithm is used to solve the tri-diagonal system. the stability of the algorithm is investigated. it ...
in this paper , the quintic b-spline collocation scheme is employed to approximate numerical solution of the kdv-like rosenau equation . this scheme is based on the crank-nicolson formulation for time integration and quintic b-spline functions for space integration . the unconditional stability of the present method is proved using von- neumann approach . since we do not know the exact solution...
The current paper is mainly devoted to construct a generalized symbolic Thomas algorithm that will never fail. Two new efficient and reliable computational algorithms are given. The algorithms are suited for implementation using computer algebra systems (CAS) such as Mathematica, Macsyma and Maple. Some illustrative examples are given.

In stochastic volatility models, European option prices are solutions to parabolic differential equations. In this paper we propose a finite difference scheme for solving these equations numerically. We prove the stability and convergence of this method in norm infinity. Then we use the ADL method to separate the operators, this allows us to apply Thomas algorithm to solve the corresponding lin...
diese wissenschaftliche arbeit, die als magisterarbeit für das studienfach „didaktik der deutschen sprache“ geschrieben wurde, befasst sich mit der novelle „der tod in venedig“ von dem berühmten deutschen schriftsteller „thomas mann“. nach kurzer vorstellung der biografie von thomas mann und der zusammenfassung und der interpretation der novelle wurde zun?chst kurze die ubersetzungstheorie und...
A very efficient direct solver, known as the Thomas algorithm, is frequently used for the solution of band matrix systems that typically appear in models of mechanics. The processor idle time is a reason for the poor parallelization efficiency of the solvers based on the pipelined parallel Thomas algorithms. In this research an efficient parallel algorithm for 3-D directionally split problems i...
The ways of using the Elliot–MacMahon algorithm to compute the Hilbert base of a system of linear Diophantine equations known so far are either not efficient or can fail to terminate. We present a version of an algorithm exploiting this range of ideas, which however is reasonably efficient as well as finite.
