Blind signature scheme, an important cryptographic primitive, is useful in protocols that guarantee the anonymity of the participants. Most of the developed blind signatures are based on a single hard problem. If one finds a solution to this problem then the blind scheme is breakable. In this paper, we presented a new blind signature scheme based on(More)
As field of signal processing is widening in various security and surveillance applications, motivated the interest for implementing better application with less complications. A non-intrusive machine vision based concepts is used to simulate Drowsiness Detection System. The system is consisting of web camera which placed in a way that it records driver's(More)

Some biomechanical models are represented by nonlinear first order ordinary differential equations. The objective of this study is to determine the velocity of a biomechanical model that involves a cyclist coasting downhill. Two methods namely; the modified explicit and diagonally implicit fifth–order Runge–Kutta methods are utilised. The performance of the(More)
