Assembly Reliability Modelling Technology Using Function Decomposing and LSSVM

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

Decomposing profit efficiency using a slack-based directional distance function

This paper develops a slack-based decomposition of profit efficiency based on a directional distance function.

Fault diagnosis of gearboxes using LSSVM and WPT

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...

Improved Reliability modelling using Bayesian Networks and dynamic discretisation

This paper shows how recent revolutionary Bayesian Network (BN) algorithms can be used to model very complex reliability problems in a simple unified way. The algorithms work for socalled hybrid BNs, which are BNs that can contain a mixture of both discrete and continuous variables. Such hybrid BNs enable us to model failure times and reliability together. The approach allows a compact represen...
