This project presents two original implementations of improved accuracy current-mode multiplier and divider circuits. Besides the advantage of their simplicity, these original multiplier and divider structures present the advantage of very small linearity errors that can be obtained as a result of the proposed design techniques (0.9% and 0.75%, respectively, for an extended range of the input c...

in this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. two objective functions, real power loss and energy not supplied index (ens), were utilized. multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

in recent years, in iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. these changes and the numerous advantages of dgs have made more incentives to use these kinds of generators than before. therefore, it is necessary to study all aspects of dgs, such as size selection and optimal placement and impact o...

In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

Sustainability should be supported by modern software engineering methods to guarantee reliability of the running systems. Dynamic reconfiguration is an important technology implementing the sustainability goal. However, building dynamic reconfigurable software system cost-effectively and in a predictable manner is a major engineering challenge. Aiming at solving this problem, this paper combin...

This paper provides a tutorial introduction to reconfigurable control and surveys recent advances on this topic. Control reconfiguration is an important method of fault-tolerant control that uses the results of a fault diagnosis component to restructure the control loop and to adapt the controller to the faulty plant. This paper describes recent approaches that are suitable for on-line applicat...

Network reconfiguration is an operation to modify the network topology. The implementation of network reconfiguration has many advantages such as loss minimization, increasing system security and others. In this paper, two topics about the network reconfiguration in distribution system are briefly described. The first topic summarizes its impacts while the second explains some heuristic optimiz...
