Since, due to numerical facts, solution of the related partial differential equation is difficult, thus we have applied integral equation model. The integral equation model of this system is a Volterra type of the first kind. These systems are ill posed system, and appropriate method for such systems are wavelets, since wavelets can be generated in the space of solutions. In this work we apply the Legendre wavelets to solve the corresponding integral equation. Numerical implementation of the method is illustrated by benchmark problems originated from heat transfer. The behavior of the initial heat function along with the position axis during the time have been shown through three dimensional plots.http://mcs.qut.ac.ir/article_44461_e0d91a7a7c4ced83f767cad225a17133.pdfQom University of TechnologyMathematics and Computational Sciences2717-27081120201001Tripled fixed point results via fractional differential equations9154446210.30511/mcs.2020.44462ENHojjatAfshariUniversity of BonabJournal Article20200509This article in want to study a class of mixed monotone operators with convexity on ordered Banach spaces and investigate some new tripled fixed point results, also in this article, we examine the existence and uniqueness of tripled fixed points without assuming the operator to be compact or continuous.

The most important linear devices in quantum optics are introduced with their differential equations. These linear quantum systems are zero-order and first-order transfer functions with one pole and one zero. We mathematical compute transfer function of different interconnections by using zero-order and first-order systems. for instance, by designing series and feedback interconnection, we will obtain higher-order quantum linear systems. Also, we will analyze a closed-loop feedback of a first-order linear quantum system containing a gain in feedback pathhttp://mcs.qut.ac.ir/article_44660_b12edffca4865591ad266f922119e6df.pdfQom University of TechnologyMathematics and Computational Sciences2717-27081120201001Investigation of light nuclei in the cluster model by means of relativistic and non-relativistic systems32424467910.30511/mcs.2020.44679ENKeivanDarooyi DivshaliDepartment of Physics, Shahrood University of Technology, Shahrood, IranMMorshedlooMohammad RezaShojaeiMMousaviJournal Article20200722Calculation of the energy of even-even isotopes using collective models in nuclear physics has its own complication. Therefor different physical models are used to study nuclear isotopes. The cluster model is a new and successful model for investigating the properties of isotopes. Using this model, the interaction between core and cluster can be chosen and static properties, including the eigenvalues energy and wave function, can be calculated. Considering the modified Eckart plus Hulthen potentials and Coulomb repulsive potential for interactions between clusters and with substituting this potential in the SchrÃ¶dinger equations, by Nikiforov-Uvarov analytical method some of the static properties including the energy levels and wave functions are obtained for 14C, 16O, 20Ne, 24Mg, 28Si, and 32S isotopes.http://mcs.qut.ac.ir/article_44679_81eaec8f931fe649075f588c994b2ffd.pdfQom University of TechnologyMathematics and Computational Sciences2717-27081120201001Sinc-Integral method to solve the linear Schrodinger equation43504486310.30511/mcs.2020.44863ENSeyed Mohammad AliAleomraninjadDepartment of Mathematics, Qom University of Technology, Qom, Iran0000-0002-9393-3584ParisaAbbasiDepartment of Mathematics, Qom University of TechnologyJournal Article20200826The integral equation method is presented to solve the linear Schrodinger equation and obtain the eigenvalues.
