Transmission expansion planning (TEP) is a non-convex optimization problem that can be solved via different heuristic algorithms. A variety of classical as well as heuristic algorithms in literature are addressed to solve TEP problem. In this paper a modified constructive heuristic algorithm (CHA) is proposed for solving such a crucial problem. Most of research papers handle TEP problem by linearization...
A MANET is a collection of mobile nodes that organize themselves into a network without any predefined infrastructure or centralized operation management and because of its especial features, is vulnerable to security attacks. In recent years, different approaches are implemented to improve the security level of MANET. The aim of this paper is to design a mechanism of intrusion detection in the MANET...
A metaheuristic technique for solving the short-term transmission network expansion and reactive power planning problems, at the same time, in regulated power systems using the AC model is presented. The problem is solved using a real genetic algorithm (RGA). For each topology proposed by RGA an indicator is employed to identify the weak buses for new reactive power sources allocation. The fitness...
This paper presents the application of a new metaheuristic algorithm to solve the transmission expansion planning problem. A simple heuristic, using a relaxed network model associated with cost perturbation, is applied to generate a set of high quality initial solutions with different topologies. The population is evolved using a multi-move path-relinking with the objective of finding minimum investment...
In this paper, we propose an efficient test environment for template based asynchronous circuits. This test environment consists of two major parts: fault simulation and test pattern generation. The fault simulation is based on exploring fault effect on quasi-delay insensitive asynchronous circuits that detects any changes in sequences of predefined signals. The test pattern generation is a high level...
In this paper we present a novel technique which localizes sound source with acceptable accuracy and low time complexity. In this technique, contrary to former localization techniques in 3-D space, only three microphones are sufficient. Instead of searching the entire space domain for the sound source, we first estimate an approximate point of the sound source according to the time delays and the...
