In this paper, a simplified model of a micro-turbine, used as distributed generator, is obtained. The model is suitable for investigating the effects of inverter modulation index on the stability of micro-turbines. The proposed model is built from the nonlinear dynamic model of a micro-turbine and then linearized. The linear model is also simplified. To(More)
In this paper, optimal generation expansion planning (GEP) is investigated considering purchase prices, profits of independent power producers (IPPs) and reliability criteria using a new method based on hybrid coded Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). In this approach, optimal purchase price of each IPP is obtained by HCGA and(More)
We describe the case of a two-year-old boy with massive burns. After the period of shock and sepsis, very successful four-phase operative treatment was performed, with combined skin grafting homograft plus autograft. With regard to the four surgical interventions, in the first two we used the above combined method, while in the other two we used grafting(More)
Quantum coherence of open quantum systems is usually compromised because of the interaction with the ambient environment. Here, we introduce the concept of Decoherence Splitting Manifold (DSM), a submanifold of the space of density operators, wherein the system's density matrix clearly exhibits a splitting between a unitarily evolving subdensity(More)
In this paper a new approach based on genetic algorithm (GA) for measurement-type current transformer (CT) design has been presented. This algorithm can present designed parameters of sample current transformer so that minimizes ratio and phase displacement errors to 1.2 times of rated current and transformer made cost also. Finally, several current(More)
Article history: Received: .................. Accepted: .................. Available online: ........ ZJRMS2015; X(X): XX-XX Background: Chlamydia trachomatis is the most common sexually transmitted bacterial infection and can cause various types of human eye disease. There are two general methods for diagnosis of chlamydial infection; cell culture and(More)
In this paper, the problem of finding the optimal topological configuration of a deregulated distribution network is considered. The new features of this paper are proposing a multiobjective function and its application on deregulated distribution networks for finding the optimal configuration. The multi-objective function will be defined for minimizing(More)
In this paper a new approach based on particle swarm optimization (PSO) for measurement-type current transformer design has been proposed. This algorithm presents design parameters of current transformer in order to minimize ratio and phase displacement errors to 1.2 times of rated current and also construction cost. It has better performance in comparison(More)
