The present scheme considers the solution in the form of a truncated Taylor series near zero with unknown coefficients. Then, by placing this approach into the problem and collocating the relation which is obtained at some nodes, a system of algebraic equations is achieved. The solution of this algebraic system is the unknown coefficients of the series. The ability of present method is examined by some examples.https://mcs.qut.ac.ir/article_252247_4673e20a67c0a2f61643c9b6536d7a88.pdfQom University of TechnologyMathematics and Computational Sciences271727083220220501Numerical Solution of System of Linear Fractional Integro-differential Equations by Least Squares Collocation Chebyshev Technique102125224810.30511/mcs.2022.543230.1050ENO TaiyeDepartment of Applied Science, Faculty of Pure and Applied Science,Federal College of Dental Technology and Therapy, Enugu, Nigerian0000-0001-9063-8806T.

IndiaJournal Article20220215Analysis of complex one-dimensional photonic systems is a challenge to the scientific community. To solve such a problem in the past computational techniques have been deployed. Transfer matrix or so-called characteristics matrix is one of the widely used methods acceptable for multilayered systems. The convectional transfer matrix method has some drawbacks to solving an annular type multilayered system. This paper presents the transfer matrix method to investigate the electromagnetic wave propagation in the annular multilayered photonic structures.https://mcs.qut.ac.ir/article_252250_0949c1ad8913362937cab4f91a89421d.pdfQom University of TechnologyMathematics and Computational Sciences271727083220220501Application of Fan sub-equation method to complex nonlinear time fractional Maccari system324025239610.30511/mcs.2022.554580.1070ENN KadkhodaDepartment of Mathematics, Faculty of Basic Sciences, Bozorgmehr University of Qaenat, Qaenat, Iran0000-0003-3042-5440Journal Article20220516In this study, the Fan sub-equation method is applied to study exact solutions of complex<br />nonlinear time fractional Maccari system.

Analytical expressions of the energy and the corresponding eigenfunctions have been obtained by using the parametric Nikiforov-Uvarov method. Special cases of the potential are discussed. In addition, numerical results of the energy are computed. Furthermore, it is reported that the energy E and the quantum numbers n and l are inversely proportional to each other.https://mcs.qut.ac.ir/article_252249_a4447f3e48bf21945401aa578d2415f3.pdf
