This paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (LSSVM). Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared to select an appropriate wavelet for feature extraction. The fault diagnosis method co...

Purpose This paper proposes a new multi-criteria decision-making method, called the vital-immaterial-mediocre method (VIMM), to determine weight of multiple conflicting and subjective criteria in problem. Design/methodology/approach The novel utilizes pairwise comparisons, vector-based procedures scoring approach weights criteria. VIMM compares alternatives by three crucial components, namely v...

Subject of the research in article is evaluation complex multifactor stochastic systems functioning effectiveness according to a variety correlated criteria. The problem actuality determined by fact that an independent system for each mutually criteria under consideration not informative. In well-known works direction multiple correlation, relatively simple estimating correlation between one re...

abstract purpose of this paper: the objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (topsis) approach to evaluate the most suitable rfid-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. design/methodology/approach: resear...

X-ray spectroscopy diagnostics have been widely used as a standard technique to determine the temperature and density of astrophysical and laboratory plasmas. Traditional techniques have relied on performing an interactive search with a graphical user interface to select theoretical model parameters that best fit the data. We use a Pareto optimal genetic algorithm to drive a search of model par...
