A new method based on principal component analysis (PCA) and artificial neural networks (ANN) is proposed for fault diagnosis of gearboxes. Firstly the six different base wavelets are considered, in which three are from real valued and other three from complex valued. Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared...

this study analyzes wind energy potentials of zanjan province which located in northwest of iran. renewable energy plans are not fully environmentally safe and different renewable energy plans have different environmental impacts. therefore, site selection is an important issue in the wind turbine installation and therefore, selecting an appropriate wind turbine site requires consideration of m...

Useful techniques for the statistical analysis and presentation of high energy particle physics data are described and discussed . DATA ANALYSIS TECHNIQUES FOR HIGH ENERGY PHYSICS TABLE OF CONTENTS Page

Statistical bounds controlling the total fluctuations in mean and variance about a basic steady 6 state solution are developed for the truncated barotropic flows over topography. Statistical ensemble predic7 tion is an important topic in weather and climate research. Here the evolution of an ensemble of trajectories 8 is considered in the statistical instability analysis and is compared and con...

The main target of this research is a quantitative review literature on global solar radiation (GSR) models available for different stations around the world. statistical analysis 400 existing sunshine-based GSR horizontal surface compared using 40-year meteorological data in selected locations Egypt. measured divided into two sets. first sub-data set from 1980 to 2019 was used develop empirica...
