A path from s to t on a polyhedral terrain is descending if the height of a point p never increases while we move p along the path from s to t. No efficient algorithm is known to ...
Design and application of super elements in efficient prediction of the structural behaviour in a short time has been one of the research interests in the last decade. A new 16-no...
ct 7 Two third order methods for finding multiple zeros of nonlinear functions are developed. One method is based on 8 Chebyshev's third order scheme (for simple roots) and th...
Let P be a polygon with n vertices. We say that two points of P see each other if the line segment connecting them lies inside (the closure of) P. In this paper we present efficie...
Recently, Lee and Yang proposed a subliminal scheme which employs an access control in a hierarchy. In their scheme, chief users use a one-way hash function to compute their subord...
