Parallel connection of inverter modules is a solution to increase reliability, efficiency and redundancy of inverters in Micro-Grid system. Proper load sharing among parallel inverters is a key point. The circulating current among the inverters can greatly reduce the efficiency or even cause instability of the system. In this paper, a control strategy for improving the load sharing performance ...

9 This paper presents a general model to define, measure and predict the efficiency of applications running on heterogeneous parallel computer systems. Using this framework, it is possible to understand the influence that the heterogeneity of the hardware has on the 11 efficiency of an algorithm. This methodology is used to compare an existing parallel genetic algorithm with a new adaptive para...

in this article, non radial method of dynamic dea with the parallel network structure is presented and is used for calculation of relative efficiency measures when inputs and outputs do not change equally. in this model, dmu divisions under evaluation have been put together in parallel. but its dynamic structure is assumed in series. since in real applications there are undesirable inputs and o...

fuzzy set based methods have been proved to be effective in handling many types of uncertainties in different fields, including reliability engineering. this paper presents a new approach on fuzzy reliability, based on the use of beta type distribution as membership function. considering experts' ideas and by asking operators linguistic variables, a rule base is designed to determine the level ...

Abstract. Effective and accurate ocean coastal wave predictions are necessary for engineering, safety recreational purposes. Refining predictive capabilities is increasingly critical to reduce the uncertainties faced with a changing global climatology. Simulating WAves in Nearshore (SWAN) widely used spectral modelling tool employed by engineers scientists, including operational forecasting For...
