A Purusit Differential Game Problem on a Closed Convex Subset of a Hilbert Space

open access: yesJournal of Nigerian Society of Physical Sciences, 2020
We study a pursuit differential game problem with finite number of pursuers and one evader on a nonempty closed convex subset of the Hilbert space l2. Players move according to certain first order ordinary differential equations and control functions of ...

Integrity Constraints Revisited

open access: yesLogic Journal of IGPL, 1996
When computerised databases began to be used in business applications, there naturally arose a concern with how the integrity the stored data could be checked. This task was irnplemented by large sets of programs, depending on each par­ ticular application.

ON THE PROPERTIES OF THE SET OF TRAJECTORIES OF THE NONLINEAR CONTROL SYSTEM WITH QUADRATIC INTEGRAL CONSTRAINT ON THE CONTROL FUNCTIONS

open access: yesUral Mathematical Journal, 2023
In this paper the control system described by a nonlinear differential equation is studied. It is assumed that the control functions have a  quadratic integral constraint, more precisely, the admissible control functions are chosen from the ellipsoid of ...

On a path integral with a topological constraint [PDF]

open access: yes, 1988
We discuss a new method to evaluate a path integral with a topological constraint involving a point singularity in a plane. The path integration is performed explicitly in the universal covering space. Our method is an alternative to an earlier method of

Constraint Based Planning with Composable Substate Graphs. [PDF]

open access: yes, 2010
Constraint satisfaction techniques provide powerful inference algorithms that can prune choices during search. Constraint-based approaches provide a useful complement to heuristic search optimal planners.We develop a constraint-based model for cost ...

Precompactness of the set of trajectories of the controllable system described by a nonlinear Volterra integral equation

open access: yesMathematical Modelling and Analysis, 2012
In this paper the controllable system whose behaviour is described by a nonlinear Volterra integral equation, is studied. The set of admissible control functions is the closed ball of the space L p (p > 1) with radius µ 0 and centered at the origin.

Square wave reference digital lock-in detection using non-orthogonal demodulation

open access: yesHeliyon, 2023
Digital lock-in detection technique is commonly used to measure the amplitude and phase of a selected frequency signal. The technique which uses a square wave as the reference signal has an advantage of easier implementation and higher computational ...

Integrity constraints in trust management [PDF]

open access: yesProceedings of the tenth ACM symposium on Access control models and technologies, 2005
We introduce the use, monitoring, and enforcement of integrity constraints in trust management-style authorization systems. We consider what portions of the policy state must be monitored to detect violations of integrity constraints. Then we address the fact that not all participants in a trust management system can be trusted to assist in such ...

Approximation of the Sections of the Set of Trajectories of the Control System Described by a Nonlinear Volterra Integral Equation

open access: yesMathematical Modelling and Analysis, 2015
Approximation of the sections of the set of trajectories of the control system described by a nonlinear Volterra integral equation is studied. The admissible control functions are chosen from the closed ball of the space Lp, p > 1, with radius µ and ...
