According Zipf's Law, city sizes follow a Pareto distribution, with the rank (R) of a city i being proportional to its size (S): R(i)=A*S-α or ln(R) = ln(A)-α*ln(S), where α is a slope gradient or Pareto parameter, varying around 1. However, several empirical studies, carried out to...

Migration is an important aspect of human society. It has existed throughout history, but in modern times it takes a new form. We propose a new approach to the world migration phenomenon as two complex directed networks (immigration and emigration) were countries represents network nodes, and...

The present study examines the spatial development of the residential build area in the city of Tel Aviv-Yafo, a metropolitan core city and a world city in evolution, over the course of 30 years. We employed spatial autocorrelation model in order to test the urban development of the city...

Construction initiation (CI) of floor area is an important socioeconomic and physical characteristic of urban structure and its evolution. Despite its importance and the availability of CI data, it has not attracted significant attention until now. Since the 1970s, the Tel Aviv-Yafo Municipality...

Small angle neutron scattering of polyacrylamide solutions and gels is presented for different polymer and cross link concentrations. The gels are analyzed in connection with their elastic properties. For less than 11% of polymer concentration and for small cross link contents c <Subscript>x</Subscript>, it was found...</subscript>
