In this paper, a method for severity fault diagnosis of ball bearings is presented. The method is based on wavelet packet transform (WPT), statistical parameters, principal component analysis (PCA) and support vector machine (SVM). The key to bearing faults diagnosis is features extraction.

To assess the frequency allele and genotypic distribution of polymorphism rs165599 in catechol-O-methyltransferase in Kinh ethnic-patients with schizophrenia. Subjects and methods: A case-control study consisted of 227 schizophrenic patients and 92 healthy controls in the Kinh ethnic. The rs165599 was genotyped by PCR-RFLP and statistical analysis was performed by Chi-Square test. Results: The frequency of allele A and G in schizophrenic patients were 72.36% and 69.94%, respectively. The frequency of allele A and G in healthy controls were 27.64% and 30.06%, respectively (p > 0.05).

The results of my statistical analysis revealed that only two variables (the number of days per year with thunderstorms and the total water equivalent precipitation) exhibited significant relationships with the percentage of work commuters who cycled or walked. Furthermore, the number of days per year with thunderstorms exhibited a strong inverse relationship, meaning that thunderstorms deterred workers from cycling or walking to work.

The Central Statistics Office has registered increased availability in part-time courses in Ireland over recent years. This study aims to investigate the motivators driving part-time study and the impact studying part-time has on professional and personal lives of full-time employees in Ireland. Utilising a qualitative research approach, data was collected using open ended, semi-structured interviews on six desirable participants and examined using thematic analysis. Extracted information was interpreted and discussed.

(BQ) Electrical discharge machining (EDM) is a widespread process which works very effectively in machining of difficult-to-cut materials and alloys in die and aerospace industries with high dimensional accuracies. However, this capability could be deteriorated due to electrode wear leading to decrease of process productivity. In this study, the effect of machining parameters of EDM process including on-time, current, voltage, the engaging time between workpiece and electrode, and pre-EDM roughing on electrode wear were experimentally investigated.

Almost all protein database search methods use amino acid substitution matrices for scoring, optimizing, and assessing the statistical significance of sequence alignments. Much care and effort has therefore gone into con-structing substitution matrices, and the quality of search results can depend strongly upon the choice of the proper matrix. A long-standing problem has been the comparison of sequences with biased amino acid composi-tions, for which standard substitution matrices are not optimal....

COMPETITIVE SUPPLY CHAIN AND REVENUE MANAGEMENT: FOUR ESSAYS When the peer group measure is interacted with the choice index—in Column B, and again with additional controls in the remaining columns—the coefficient is indistinguishable from zero, with a negative point estimate in every specification. Panel B repeats this analysis, this time with the score earned by students when they were in the 12th grade.51 Again, estimates of the choice effect are imprecise but are—with one statistically insignificant exception—of the opposite sign from that predicted by the economic model....
