due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
The paper considers the Baer-Nunziato model for two-phase flow in porous media, with discontinuous porosity. Computing solutions of the Riemann problem rests on capturing the jump in the solution across the porosity jump. A recent study [8] showed that numerical discretizations may fail to correctly capture the jump conditions across the so-called compaction wave, and yield incorrect solutions....
Option pricing based on GARCH models is typically obtained under the assumption that the random innovations are standard normal (normal GARCH models). However, these models fail to capture the skewness and the leptokurtosis in financial data. We propose a new method to compute option prices using a non-parametric density estimator for the distribution of the driving noise. We investigate the pr...
In this paper, we propose a novel Zaslavsky map based pseudorandom bit generation scheme. The output numbers are statistically tested with NIST, DIEHARD, and ENT test packages. The study indicates that the presented algorithm is suitable for varied cryptographic applications. Mathematics Subject Classification: 94A60, 14G50, 68P25, 65P30
Background and purpose: In order to design an industrial-scale adsorption process, it is necessary to model exact simulation of the dynamic behavior of fixed bed adsorption system. This study aimed at evaluating the performance of fixed bed column using sucrose-modified pumice in removal of metronidazole from aqueous phase. Materials and methods: In this experimental study, the adsorbent was p...
This paper introduces fully computable two-sided bounds on the eigenvalues of the Laplace operator on arbitrarily coarse meshes based on some approximation of the corresponding eigenfunction in the nonconforming Crouzeix-Raviart finite element space plus some postprocessing. The efficiency of the guaranteed error bounds involves the global mesh-size and is proven for the large class of graded m...
Utopian thoughts have precedence as old as human history. Islamic civilization utopian thought owes its progress to the Farabi&rsquos utopian concept and expansion and academic study of utopian term in west owes to the Thomas More Utopia book. Theoretically, Farabi&rsquos utopian thoughts influenced development of utopian system in both Islam and Western civilizations. By emphasis on Farabi&rsq...

In this paper we present a-posteriori error estimator for the mixed formulation of linear parabolic problem, used in designing an efficient adaptive algorithm. Our spacetime discretization consist of lowest order Raviart-Thomas finite element over graded meshes, and discontinuous Galerkin method with varying time-steps. Finally, several examples show that the proposed method is efficient and re...
