Specification and Analysis of ABAC Policies in a Rule-Based Framework,that are evaluated against the attributes of entities (user, subject, and object), operations, and the environment relevant to a request. Many ABAC models, with different variations, have been proposed and formalized. Since the access control policies that can be implemented in ABAC have inherent ru

Study of Three-Layer Semi-Discrete Schemes for Second Order Evolution Equations by Chebyshev Polynos are proved for approximate solutions, as well as for difference analogues of first and second order derivatives. Using these a priori estimates we obtain estimates of the approximate solution error and, taking into account the smoothness of the solution of the continuous problem, the rate of conve

Localized Boundary-Domain Integro-Differential Equations Approach for Stationary Heat Transfer Equae stationary heat transfer partial differential equation (PDE) with a variable coefficient are obtained and analysed. Localization is performed by a non-smooth parametrix represented as the product of a global parametrix and the characteristic function of a ball centered at a reference point. The eq

Review of Rational Electrodynamics: Deformation and Force Models for Polarizable and Magnetizable M localization of global balance laws. The mathematical tools for the localization in a spatial description are presented. Subsequently the balance laws of electric charge and magnetic flux are discussed and localized in order to obtain .’s equations. Furthermore, short historical remarks on the orig
