(Sudan University of Science and Technology, 2019-11-22)IVAbstractSchrodinger equation for particle in a finite media with uniform potential inside abox has been solved the solution which is based on the fact that the particle exists gives complex and cosine wave ...
-
(Sudan University of Science and Technology, 2020-02-24)The application of Adomian’s decomposition method and its modifications to partial differential equations, when the exact solution is not reached, demands the use of truncated series. But the solution’s series may have ...
-
(Sudan University of Science and Technology, 2019-12-10)Binary logistic regression (BLR) and Linear discriminant analysis (LDA) are often used for the purpose of classifying populations or groups using a set of predictor variables. The goal of this study is to compare two ...

(Sudan University of Science and Technology, 2020-01-10)A characterization of product and multi-paraproducts of bounded mean oscillations with upper bound for multi-parameter and higher order Journé commutators are studied. We describe an algorithm of nonlinear piecewise ...
-
(Sudan University of Science and Technology, 2020-01-10)We deal with the integral–type operator from Bloch space, logarithmic Bloch space and Dirichlet space to the Bloch-type space on the unit ball. The norm of operators from logarithmic Bloch type spaces to weighted- type ...
-
(Sudan University of Science and Technology, 2020-01-10)The 𝐿𝑝 norm estimates and an improvement of eigenfunctions restricted to submanifolds, for compact boundaryless Riemannian manifolds with nonpositive sectional curvature and constant negative curvature are studied. We ...
-
(Sudan University of Science and Technology, 2019-12-10)Frames and continuous framings for Banach spaces are constructed . We introduce the Frames associated and expansions with measurable spaces, in separable Banach spaces , Riesz bases, and sampling expansions in Banach ...
-
(Sudan University of Science and Technology, 2019-10-10)The Leavitt path algebras and simplicity of lie algebras associated to Leavitt algebras are considered. We give the crossed products of l^p-operator algebras, the k-theory of Cuntz algebras generated on l^p- spaces. The ...
-
(Sudan University of Science and Technology, 2020-01-10)In the context of the lifetime data analysis, some models consider the assumption of the proportional hazard rate or the assumption of the proportional mean residual life. The foregoing models have developed rapidly in ...
