Voltage dips represent a significant power quality problem. The main cause of voltage and short-term interruptions is an electrical short circuit that occurs in transmission or distribution networks. Faults the system are stochastic by nature dips. As faults can affect more customers than system, to reduce number dips, it not enough invest small part system. Only targeted investment whole (or l...

Pain is a useful sensation. Nociceptive pain provides warning of impending or actual tissue damage and prompts aversive or attentive actions that protect the body from harm. People who do not feel pain, due to mutation of certain ion channels (1), suffer a lifetime of otherwise avoidable injuries. The consequences of losing the ability to feel pain also are highlighted by the symptoms and clini...

Thanks to Pylyshyn's work in the imagery debate, theorists are now apt to be at least a bit more cautious when they launch into descriptions of depictive representation. Even if the full force of his critique is not everywhere acknowledged, more care and vigilance is exercized when broaching talk of scanning mental images, focusing on such entities, or rotating them. The very places found in me...

location-allocation is a combinatorial optimization problem, and is defined as non deterministic polynomial hard (np) hard optimization. therefore, solution of such a problem should be shifted from exact to heuristic or meta heuristic due to the complexity of the problem. locating medical centers and allocating injuries of an earthquake to them has high importance in earthquake disaster managem...

This paper presents a bi-objective capacitated hub arc location problem with single assignment for designing a metro network with an elastic demand. In the literature, it is widely supposed that the network created with the hub nodes is complete. In this paper, this assumption is relaxed. Moreover, in most hub location problems, the demand is assumed to be static and independent of the location...

Location-Routing Problem (LRP) emerges as one of the hybrid optimization problems in distribution networks in which, total cost of the system would be reduced significantly by simultaneous optimization of locating a set of facilities among candidate locations and routing vehicles. In this paper, a mixed integer linear programming model is presented for a two-echelon location-routing problem wit...
