Normalized cross correlation (NCC), Sum of squared differences (SSD), and Sum of absolute differences (SAD) are the linear correlation measures generally used for stereo correspondence. These measures fail to establish the correspondence under nonideal conditions such as specular reflection, occlusion etc. In this paper, the similarity measures for stereo correspondence based on rank correlatio...

Contact probing is the preferable method for studying mechanical properties of thin two-dimensional (2D) materials. These studies are based on analysis of experimental force-displacement curves obtained by loading of a stretched membrane by a probe of an atomic force microscope or a nanoindenter. Both non-adhesive and adhesive contact interactions between such a probe and a 2D membrane are stud...

This paper deals with the research of monthly precipitation trends in climatic stations in Libya and Slovakia. The non-parametric Mann-Kendall statistic test was applied to detect trends and to assess the significance of the trends in the time series. The evaluation was done for the time period from November to October. Trend analysis of rainfall data series for 1970–2010 did not show any clear...

It is well established that hepatic abnormalities may occur in patients with rheumatoid arthritis (RA) and other connective tissue disorders and these changes have usually been attributed to the systemic nature of the underlying disease process. Abnormalities reported include minor derangements of liver function (Movitt and Davis, 1953) and other abnormalities which have been related to the sev...

The search for species associations is one of the classical problems of community ecology. This article proposes to use Kendall’s coefficient of concordance (W ) to identify groups of significantly associated species in field survey data. An overall test of independence of all species is first carried out. If the null hypothesis is rejected, one looks for groups of correlated species and, withi...
