A wavelet‐integration‐free periodic wavelet Galerkin BEM for 2D potential problems

Jin‐you Xiao, Li‐hua Wen, Duo Zhang

This paper seeks to present a wavelet Galerkin boundary element method (WGBEM) for solving 2D Laplace's equation in which the coefficient matrices are exactly computed through…

FM – a pragmatic tool to model, analyse and predict complex behaviour of industrial systems

Rajiv Kumar Sharma, Dinesh Kumar, Pradeep Kumar

This paper aims to permit the system reliability analysts/managers/practitioners/engineers to analyze the system failure behavior using fuzzy methodology (FM)

An integrated PCA DEA framework for assessment and ranking of manufacturing systems based on equipment performance

A. Azadeh, S.F. Ghaderi, V. Ebrahimipour

Competing risks for reliability analysis using Cox's model

F.A.M. Elfaki, I. Bin Daud, N.A. Ibrahim, M.Y. Abdullah, M. Usman

Cox's model with Weibull distribution and Cox's with exponential distribution are the most important models in reliability analysis. This paper seeks to show that, with a large…

Investigation of WBZ‐α method for solving nonlinear systems

Shuenn‐Yih Chang

It has been verified that the WBZ‐α method of Wood, Bossak and Zienkiewicz can have unconditional stability and numerical dissipation for linear elastic systems. However, it is…

Extension of unsymmetric finite elements US‐QUAD8 and US‐HEXA20 for geometric nonlinear analyses

Ean Tat Ooi, Sellakkutti Rajendran, Joon Hock Yeo

This paper aims to present an extension of two recently published elements (which are based on Petrov‐Galerkin formulation) to geometric nonlinear (GNL) problems.
