In this paper, effect of the islands number variation in restoration process is investigated and a graph based method for determination of optimum islands boundaries is presented. Also, the effect of number and location of black-start units on the restoration process is evaluated. In optimization process, objective function is minimizing Energy Not Supplied (ENS) and constraints are voltage mar...

distributed generation (dg) sources are becoming more prominent indistribution systems due to the incremental demands for electrical energy. locationsand capacities of dg sources have great impacts on the system losses in adistribution network. this paper presents a study aimed for optimally determiningthe size and location of distributed generation units in distribution systems withdifferent l...

This paper aims at investigating the optimum location of a single longitudinal stiffener having various cross-section types steel plate girders subjected to bending loading. The is found using gradient-based Interior-Point (IP) optimization algorithm. procedure involves linear elastic buckling analysis with finite element method, which coupled aforementioned IP algorithm and used calculate coef...

In this paper optimum size and location of capacitors and distributed generations (DGs) are determined simultaneously in a radial distribution network. The objective function includes power losses reduction and voltage profile improvement using ant colony algorithm. Allocation capacitors and of DGs should be carefully determined with the consideration of different planning incentives. It shows ...

In this paper, we introduce a new location-based routing protocol INGEO (INdoor GEOgraphic Routing Protocol) for ad hoc networks based on an indoor location system. We aim at extracting an optimum topology from the dynamic and irregular topology of a mobile ad hoc network to reach more quickly the destination applying an indoor geographic routing. Our scheme operates in a loopfree manner and at...

The black box has the function that stores driving video, location, time and rear-end collision before/after the accident with mounted on the vehicle. And, in case of car accident, it has GPS function to find the location of accidents. In this paper, the system was designed that traces the moving path of the vehicle and transmits current location of vehicle and the videos of accident happened d...
