Communal behavior refers to how individuals perform when they are viewing in social network Location. Load of data generated by social media like Facebook, Twitter, Flickr and YouTube present opportunity and challenges to studying communal performance in a huge range. The range of networks entails scalable learning of models for combined behavior forecast. To deal with the scalability question,...

background and purpose: sample size and its determination is one of the most important problems in health researches. calculating sample size for prevalence studies is one of the common questions of sample size topics. minimum sample size with least complexity is desirable in order to achieve the basic goal of these studies. this study aims to compare two formulas of sample size calculation for...

When Dan Shechtman entered the discovery awarded with the Nobel Prize in Chemistry 2011 into his notebook, he jotted down three question marks next to it. The atoms in the crystal in front of him yielded a forbidden symmetry. It was just as impossible as a football – a sphere – made of only sixcornered polygons. Since then, mosaics with intriguing patterns and the golden ratio in mathematics an...

The beta model is the most important distribution for fitting data with unit interval. However, not suitable to bimodal interval data. In this paper, we propose a constructed by using an approach based on alpha-skew-normal model. We discuss several properties of distribution, such as bimodality, real moments, entropies and identifiability. Furthermore, new regression proposed residuals. Estimat...

Human’s disregard to nature and consequently his living environment’s distance from natural endowments and potentials have caused many problems. Human’s living spaces are less desirable for him, and have destroyed his comfort in many cases, as man-made things. In this regard, public open spaces in residential areas can be mentioned because they are usually considered among the most vulnerable s...
