Reconstruction of broken fragments is an extremely difficult task, mainly due to the high probability of missing pieces and the likelihood of erosion. This process is tedious and requires many hours to complete even for the experienced archaeologist. This paper describes some of the most successful fragment reconstruction algorithms and presents a new technique for reassembly. The technique rel...

background: one of the factors that can improve self-concept and performance of staff is professional maturity. professional maturity can also solve the problems of self-concept. the purpose of this paper was to identify the relationship between the dimensions of self-concept and professional maturity.   materials and methods: this relative applicable study was performed on all the personnel (n...

Pearson product-moment correlation coefficients are a wellpracticed quantification of linear dependence seen across many fields. When calculating a sample-based correlation coefficient, the accuracy of the estimation is dependent on the quality and quantity of the sample. Like all statistical models, these correlation coefficients can suffer from overfitting, which results in the representation...

Kendall Rank Correlation Let (X1, Y1), · · · , (Xn, Yn) be a bivariate random sample of size n. The Pearson correlation coefficient provides an optimal measure of the degree of association between the X’s and the Y ’s when the sample is drawn from a bivariate normal distribution. The Pearson correlation coefficient is reasonably robust for many other distributions as well. The Kendall correlati...
