Abstract The renewable based energy source integration into the smart grid has seen a rapid surge lately and so role of distributed energy. By reducing power losses within distribution network, appropriate location size or generation sources could be found. In this paper, it been proposed that where generating units should placed. An intelligent optimization technique utilized to position diffe...

Owing to trade imbalance, shipping companies position empty containers between ports or depots periodically. The most difficult problem for positioning is that it is not possible to know the exact amounts of empty containers required in the future. The paper deals with the problem of positioning empty containers in a port area with multiple depots. Customer demands and returning containers in d...

Wireless Sensor Networks (WSNs) are networks of autonomous nodes used for monitoring an environment. In designing WSNs, one of the main issues is limited energy source for each sensor node. Hence, offering ways to optimize energy consumption in WSNs which eventually increases the network lifetime is strongly felt. Gravitational Search Algorithm (GSA) is a novel stochastic population-based meta-...
