Non-Universality in Semi-Directed Barabasi-Albert Networks
M. A. Sumour, M. A. Radwan
In usual scale-free networks of Barabasi-Albert type, a newly added node selects randomly m neighbors from the already existing network nodes, proportionally to the number of links…
Statistical physics applied to stone-age civilization
M. A. Sumour, M. A. Radwan, M. M. Shabat +1
About 45,000 years ago, symbolic and technological complexity of human artefacts increased drastically. Computer simulations of Powell, Shennan and Thomas (2009) explained it throu…
Highly Nonlinear Ising Model and Social Segregation
M. A. Sumour, M. A. Radwan, M. M. Shabat
The usual interaction energy of the random field Ising model in statistical physics is modified by complementing the random field by added to the energy of the usual Ising model a…
Urban segregation with cheap and expensive residences
M. A. Sumour, A. H. El-Astal, M. A. Radwan +1
In this paper we study urban segregation of two different communities A and B, poor and rich, distributed randomly on finite samples, to check cheap and expensive residences. For t…
Simulation of Demographic Change in Palestinian Territories
M. A. Sumour, A. H. El-Astal, M. M. Shabat +1
Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertilit…
