    Characterizing the aperiodic behavior of seismic waves using the scale index analysis
    (Springer Science and Business Media Deutschland GmbH, 2021) Department of Physics; Yılmaz, Nazmi; Teaching Faculty; Department of Physics; College of Sciences; 178427
    The scale index analysis determines the degree of aperiodicity and chaos in nonlinear dynamical systems. The scale index parameters provide quantitative information on the aperiodicity and chaos in a system in the interval between 0 and 1. Aperiodicity and chaotic behavior of the seismic waves can be studied by this wavelet-based method. In this work, the method is applied firstly to the Duffing oscillator for calibration and secondly to the time series of selected seismic waves to determine and classify their aperiodic and chaotic characteristics. The results indicate that the method is efficient in distinguishing aftershocks from independent earthquakes. The scale index parameters computed from the time series of 23 October 2011, 10:41:21 Van-Tabanlı (ML:6.6) earthquake are in the range of 0.67–0.98, indicating relatively strong aperiodicity hence strong chaotic behavior. On the other hand, the parameters computed from the time series of 09 November 2011, 19:23:33 Van-Edremit (ML:5.6) earthquake are in the range of 0.27–0.62, showing relatively weak aperiodicity hence weak chaotic behavior. The scale index analysis is presented as a unique quantitative approach in seismic wave comparison, complementary to the established seismological analysis techniques.

    Women's rights and minorities' rights in Canada: the challenges of intersectionality in Supreme Court jurisprudence
    (De Gruyter Open, 2017) N/A; Scotti, Valentina Rita; College of Social Sciences and Humanities
    After a discussion of the impact of the principle of equality, entrenched in the Charters approved in Canada since the 1867 British North American Act, this essay then focuses on the related Supreme Court's adjudications. A brief analysis of the case-law concerning gender equality is followed by the discussion of cases of Aboriginal and Muslim women with the aim of assessing whether intersectionality represents for these groups of women a source of double discrimination. Brief concluding remarks discuss the challenges deriving from the different options for accommodating the principle of equality with cultural rights.
