Microgrid (MG) systems effectively integrate a generation mix of solar, wind, and other renewable energy resources. The intermittent nature resources the unpredictable weather conditions contribute largely to unreliability microgrid real-time operation. This paper investigates behavior for different scenarios photovoltaic in real-time. Reactive power coordination control load shedding mechanism...

after springs production, different residual stresses are created in the inner and outer surfaces of spring wires. some of these stresses for example compressive residual stresses are useful and some are harmful. the effects of vareation of these stresses are caused spring relaxation and decrising in their free length when they are loaded intermittently. for review this phenomena in this resear...

A dynamic model for the simulation of the batch operation of a multicomponent packed distillation column is developed. The accuracy of simulation code is verified by using two types of mixtures (cyclohexane-n-heptane-toluene and ethanol–water) theoretically and experimentally. An optimum internal reflux ratio profile is searched to maximize the distillate amount of a specified concentration for...

The present research work aims to demonstrate the effectiveness of the new methodology of Design of Dynamic Experiments (DoDE) in optimizing an important pharmaceutical reaction. An easily developed response surface model (RSM) is used instead of a hard to develop knowledge-driven process model. The DoDE approach allows the experimenter to introduce dynamic factors in the design, which during t...

In hyperthermia treatment planning (HTP) the goal is to find the amplitudes and phases of antennas in the applicator to efficiently heat the tumor. To do this prior information regarding tumor characteristics such as the size, position and geometry, in addition to an exact model of the hyperthermia applicator is needed. Based on this information, the optimal frequency of operation can be determ...

This paper describes the development of a genetic algorithm (GA) based path-planning software for local obstacle avoidance. The GA uses a novel encoding technique, which was developed to optimize the information content of the GA structure. Simulation results were used to further optimize the developed software and determine its optimum field of operation. The results show that the GA finds val...

performance of chamomile (matricaria chamomilla l.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of wondo genet agricultural research center; using rcbd design with three replications. transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...
