We describe a strategy for optimal memory and work distribution. We have performed a series of tests to find an optimal data distribution in the Cray T3D memory, and to identify a strategy for the Dynamic Load Balance (DLB). The results of tests show that the step duration depends on two main factors: the data locality and the network contention. In a very large simulation, due to network conte...

A multiphysics asynchronous electric machine model based on the angular approach is developed in this paper by adding interaction between Unbalanced Magnetic Pull and rotor center radial displacements to reinforce electro-magneto-mechanic fields couplings. The novelty of proposed lies also calculating instantaneous speed shaft therefore tackling problems non-stationary operating conditions. Thi...

In this paper, using particle swarm optimization (PSO) based method is developed to determine the optimal allocation of distributed generators (DGS) on a multi phased unbalanced distribution network. PSO algorithm has been programmed in MATLAB using open source software called OpenDSS in a cosimulation environment to solve the unbalanced three-phase optimal power flow (TOPF) and to find the opt...

The reliability of distribution networks is inherently low due to their radial nature, consequently distribution companies (DisCos) usually seek to improve the system reliability indices with the minimum possible investment cost. This can be known as system-oriented reliability planning (SORP). However, there can exist some customers that are not satisfied by their reliability determined by ado...

radiotherapy dose calculations can be evaluated by monte carlo (mc) simulations with acceptable accuracy for dose prediction in complicated treatment plans. in this work, standard, livermore and penelope electromagnetic (em) physics packages of geant4 application for tomographic emission (gate) 6.1 were compared versus monte carlo n-particle extended (mcnpx) 2.6 in simulation of 6 mv photon lin...

Connections of distributed generation (DG) in distribution networks are increasing. These connections of distributed generation cause voltage rise in the distribution network. This paper presents a detail analysis of how does voltage rise on distribution network due to the penetration of distributed generation. This paper also presents how does the voltage rise affect the connection of distribu...

This paper presents a new design method of balance weights with phase angles for scroll compressors. Based on force and moment balances on crankshaft and compressor frame, mathematical formulation of shaft bearing loads, unbalanced force and moment acting on the frame has been made in terms of balance weight design parameters such as masses and phase angles of the upper and lower balance weight...
