We generalize here the use of the 1D Boolean model for the analysis of grey level textures. Each grey image is first split into eight binary images using different criteria. Each of these binary images is separately analysed with the help of the 1D Boolean model and features are extracted from it. The final grey texture recognition is performed on the basis of these features using several class...

The main purpose of this study is to evaluate the financial Performance of four listed Taiwanese airline companies by combining grey theory and principal component analysis. The absolute degree of grey incidence (ADGI) matrix was introduced to replace the correlation matrix of the traditional PCA, and build an evaluation model of grey principle component analysis (GPCA). Based on this model, th...

The main research intent of this paper is to introduce the use of fault tree analysis (FTA) and failure mode and effects analysis (FMEA) in conjunction to analyse the risk and reliability of a complex mechatronic system in both qualitative and quantitative manner. The major focus is on handling imprecise and vague information with the help of fuzzy synthesis of information. A complex mechatroni...

The aim of this research is to investigate the optimization of cutting parameters (cutting speed, feed rate and depth of cut) for surface roughness and metal removal rate in turning of AISI 8620 steel using coated carbide insert. Experiments have been carried out based on Taguchi L9 standard orthogonal array design with three process parameters namely cutting speed, feed rate and depth of cut f...

We have constructed an ǫ-finite basis of master integrals for all new types of one-scale tadpoles which appear in the calculation of the four-loop QCD corrections to the electroweak ρ-parameter. Using transformation rules from the ǫ-finite basis to the standard " minimal-number-of-lines " basis, we obtain as a by-product analytical expressions for few leading terms of the ǫ-expansion of all mem...
