Baniamerian, Z.,

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...

The Axis II Work Group of the Task Force on DSM-IV has expressed concern that antisocial personality disorder (APD) criteria are too long and cumbersome and that they focus on antisocial behaviors rather than personality traits central to traditional conceptions of psychopathy and to international criteria. We describe an alternative to the approach taken in the rev. 3rd ed. of the Diagnostic a...

The Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) workgroup for disruptive behavior disorders is considering adopting a frequency threshold for symptoms of oppositional defiant disorder (ODD). In the present study, the impact of substituting the term "often" with a specific age-based frequency on impairment and prognosis among preschool children was tested in a l...

The resolution of coherent and incoherent imaging systems is usually evaluated in terms of classical resolution criteria, such as Rayleigh's. Based on these criteria, incoherent imaging is generally concluded to be 'better' than coherent imaging. However, this paper reveals some misconceptions in the application of the classical criteria, which may lead to wrong conclusions. Furthermore, it is ...

Credit scoring has been regarded as a core appraisal tool of different institutions during the last few decades, and has been widely investigated in different areas, such as finance and accounting. Different scoring techniques are being used in areas of classification and prediction, where statistical techniques have conventionally been used. Both sophisticated and traditional techniques, as we...

The utility of a variety of objective, quantitative and robust methods of assessing similarities between antenna measurement data have already been highlighted in the literature. These techniques essentially involved the extraction of interval, ordinal, and categorical features from antenna pattern data sets that can then be effectively compared to establish a measure of their adjacency, i.e. s...

We proposed a simple formula to assess the statistical significance of homologous segments found in comparison of two nucleic acid sequences (Goad and Kanehisa, Nucleic Acids Res. 10, 247-263, 1982). This paper clarifies the basic assumptions of the formula and its reliability is examined by Monte Carlo calculations. The results were satisfactory for random sequences. The formula is a useful me...

Recently, many organizations have opened up their data for others to reuse. A major part of these data concern statistics such as demographic and social indicators. Linked Data is a promising paradigm for opening data because it facilitates data integration on the Web. Recently, a growing number of organizations adopted linked data paradigm and provided Linked Open Statistical Data (LOSD). Thes...
