A four site monitoring network was established in the Missouri portion of Metropolitan St. Louis during 2008 to characterize spatiotemporal patterns in PM10 arsenic. Arsenic measured at two urban sites in the City of St. Louis was typically higher than arsenic at two suburban sites. Spatiotemporal variability in arsenic is examined by plotting the Pearson correlation coefficient (PCC) against t...

In this paper, we answer the question of what are the necessary conditions under which Correlation Power Attack (CPA), that essentially targets embedded cryptographic implementations, is optimal with regards to attacks that exploit the same leakage model. For this purpose, we offer an in-depth theoretical study which aims at determining the conditions under which the Pearson correlation coeffic...

Collaborative filtering, a widely-used user-centric recommendation technique, predicts an item’s rating by aggregating its ratings from similar users. User similarity is usually calculated by cosine similarity or Pearson correlation coefficient. However, both of them consider only the direction of rating vectors, and suffer from a range of drawbacks. To solve these issues, we propose a novel Ba...

background: occupational stress occurs when job needs do not comply with the abilities, support, and needs of the employee. in addition to negatively affecting the physical and mental health of individuals, occupational stress can reduce their efficiency and productivity in organizations. this paper investigated the rate of job stress and its relation to absenteeism in workers. methods: in this...

Absolute Mean Brightness Error (AMBE) and entropy are two popular Image Quality Analyzer (IQA) metrics used for assessment of Histogram Equalization (HE)-based contrast enhancement methods. However, recent study shows that they have poor correlation with Human Visual Perception (HVP); Pearson Correlation Coefficient (PCC)<0.4. This paper, proposed a new IQA which takes into account important pr...

On the basis of 2200 small (10-100) samples obtained from four random number populations, it is shown that the rank correlation coefficient, p, is 88 adequate a measure of concordance 88 the Pearson product-moment correlation, T. The samples were obtained by using pseudo-random linear and normal number generators for bivariate populations with expected correlation cC'efficientB, r~, of 0.0 and ...
