Based on radial basis functions approximation, we develop in this paper a new computational algorithm for numerical diļ¬erentiation. Under an a priori and an a posteriori choice r...
This paper solves the visual cryptography problem by the Blakley scheme that is a geometry-based secret sharing strategy. We first partition the protected image into non-overlappi...
We investigate optimal control problems subject to mixed control-state constraints. The necessary conditions are stated in terms of a local minimum principle. By use of the Fischer...
We address long-term coalitions that are formed of both customer and vendor agents after evaluating their trust relationships with other agents in the system. We present a coalitio...
This paper shows that for unitary Hessenberg matrices the QR algorithm, with (an exceptional initial-value modification of) the Wilkinson shift, gives global convergence; moreover,...
