This paper deals with the problem of function projective synchronization for a class of memristor-based Cohen–Grossberg neural networks with time-varying delays. Based on the theory of differential equations with discontinuous right-hand side, some novel criteria are obtained to realize the function projective synchronization of addressed networks by(More)
Constraints are considered to be the principal motivation for RBAC model. XACML profile for RBAC can not meet the need of expressing static and dynamic RBAC constraints well. We give the XACML syntax of common static and dynamic Separation of Duty constraints and cardinality constraints of RBAC. We also complement Role Enablement Authority to extend this(More)
In this paper, we present a fourth-order finite difference method for solving nonlinear one-dimensional Burgers equation. This method is unconditionally stable, fourth-order accurate in space and second-order accurate in time. Accuracy of the scheme is demonstrated by solving a test problem, and the numerical results obtained by this method for different(More)
Access control constraint aims to avoid risky or sensitive set of objects being possessed by similar subjects. In order to improve the flexibility of constraints, this paper first examines potential inner-relationships among subjects, objects, and also the relationships between them in access control respectively, then proposes revised attribute-based(More)
