The coaxiality and unbalance are the two important indexes to evaluate assembly quality of an aeroengine. It often needs be tested disassembled repeatedly meet double-objective requirements at same time. Therefore, intelligent method is urgently needed directly predict optimal orientations rotors each stage simultaneously. In this study, optimization for multistage rotor aeroengine proposed bas...

Power system signals are associated with different types of abnormalities, which degrade efficiency of equipments and renders in their erratic operation. One of the causes of power quality degradation is unbalance in supply, which deteriorates the performance of induction motors, which is seen to be the most suitable drive for industrial applications. The objective of this work is to diagnose t...

ENETIC load has been defined as the extent to which an equilibrium population is impaired because not all individuals are of optimum genotype. The concept, first discussed by HALDANE (1937), is the basis of theory developed by CROW (1958) and others for assessing the relative impact of various facets of the genetic system (especially mutation, segregation and inbreeding) on the average fitness ...

Over the last decade, the battery energy storage system (BESS) has become one of the important components in smart grid for enhancing power system performance and reliability. This paper presents a strategy to shave the peak demand and mitigate the voltage unbalance of the electrical networks using a BESS. The BESS is developed to reduce the peak demand and consequently the electricity bill of ...

During the voltage unbalance, the resulting adverse effects on equipments such as induction motors and power electronic converters and drives on ASDs have been described. It has been observed that during unsymmetrical fault, the input rectifier slips into the single phase operation and draw heavy currents which may actuate the overload protection and trip the ASDs. The application of supercapac...

Abstract At present, the voltage level of a commercial SiC MOSFET can hardly meet requirements high-voltage field. For sake achieving application MOSFETs in fields, method series-connected has become practical and effective solution. However, multiple face problem unbalance, especially dynamic unbalance. Generally, unbalance could be solved using load side sharing schemes or methods gate side. ...

Personalized medicine is a hot topic to develop a medical procedure for healthcare. Motivated by molecular dynamics simulation-based personalized medicine, we propose a novel numerical simulation-based personalized diagnosis methodology and explain the fundamental procedures. As an example, a personalized fault diagnosis method is developed using the finite element method (FEM), wavelet packet ...
