In this paper, we investigate the problem of designing compact support interpolation kernels for a given class of signals. By using calculus of variations, we simplify the optimization problem from an infinite nonlinear problem to a finite dimensional linear case, and then find the optimum compact support function that best approximates a given filter in the least square sense (l2 norm). The be...

ii i Direct-Sequence Code Division Multiple-Access (DS/CDMA) has for some years been considered as a candidate for future personal and mobile communications. The reasons are mainly the properties of universal frequency reuse and the multipath mitigation. Generally, the focus has been on low rate services such as speech, and very little has been done on evaluating the performance for a system th...

in recent decades, information technology systems and tools play an essential role in improving the method for responding the requests from managers. decision support system as an important tool has the fundamental role in organizations. in the team of software project allocating people to tasks has a noticeable effect on profits. a decision support system can help managers in making appropriat...

the management and analysis of flood hazards is of great socio- economic and ecological importance as it was estimated that 50 percent of word’s population resides and works within the costal zone till 2030. the management of coastal flood hazard reflects the cumulative effects and criteria more than the human mind can handle effectively. the flood management requires decision making for rela...
