Abstract. Consider the random normal matrix ensemble associated with a potential on the plane which is sufficiently strong near infinity. It is known that, to a first approximation, the eigenvalues obey a certain equilibrium distribution, given by Frostman’s solution to the minimum energy problem of weighted logarithmic potential theory. On a finer scale, one can consider fluctuations of eigenv...

We propose the use of maximum-entropy techniques to nest and test the functional form of commonly used yield densities. We demonstrate how common parametric yield models can be nested within a maximum-entropy framework and subsequently tested for using standard hypothesis tests. We include an empirical application that tests the beta distribution against a more general maximum-entropy alternati...

the purpose of this paper is to analyze the utility operating radius and service on city parks in ardabil neighborhood, local, regional and urban level, to investigate the relationship between the distribution of these parks with water levels in the city of ardabil, including shorabil lake and balyqlv river and reviews for distribution park. the data and information used by documentary. to anal...

odonata fauna is poorly known in iran and most of the previous studies deal with northern parts of the country, studying adult specimens. we sampled karun river for aquatic insects in the city of ahvaz in south-west of iran during 2009–2011. as a result, 40 nymphs of one damselfly species and four dragonfly species of the order odonata comprising five genera from four families were recorded. al...

The city environment in the central part of the capital of Japan, Tokyo has been investigated by using high-resolution satellite images. The accumulation of environmental information necessary to create a good quality, city environment has been advanced. Up to now, the environmental information has been examined for the amount of distribution and the distribution shape of small-scale vegetation...

Problem statement: The aim of this study is to create a GIS application for retail facilities planning in Saudi Arabia. Jeddah city has been selected as a case study representing a major commercial city in Saudi Arabia. Approach: The crated application covers several retail planning analysis issues. These issues are divided in to two major groups called the city scale retail planning and the re...

The tick is a well-known vector for arthropod-borne pathogens, such as tick-borne encephalitis, Lyme disease, Japanese spotted fever and severe fever with thrombocytopenia syndrome. It is therefore important to know the tick population and distribution in our environment and wild animals in order to prevent tick-borne diseases. Here, we report the results of tick surveillance from May to Septem...
