Most statistics students know that the sample correlation coefficient R is used to estimate the population correlation coefficient ρ. If the pair (X, Y) has a bivariate normal distribution, this would not cause any trouble. However, if the marginals are nonnormal, particularly if they have high skewness and kurtosis, the estimated value from a sample may be quite different from the population c...

Current metrics used in summarizing networks, such as degree distribution, average diameter and clustering coefficient, provide a very coarse understanding of their structure. One would like to have finergrained summaries of networks which allow making distinction between structurally different networks. A class of such interesting graph statistics are the Small Subgraph Frequencies. These subg...

In this paper, a new local-world evolving network model including triad formation mechanism is proposed and studied. Analytical expressions for degree distribution and clustering coefficient are derived using continuum theory. It is shown that the degree distribution transfers from exponential to power-law scaling, and the clustering coefficient is tunable with known parameters. Finally, the nu...

Determination of the heat transfer coefficient (HTC) distribution is important during design and operation many devices in microelectronics, construction, car industry, drilling, power industry research on nuclear fusion. The first part manuscript shows works describing how a change affects devices. Next, various methods determining are presented. most common method to determine HTC use Newton’...
