      Distribution of number of neighbors on semi-directed Barab'asi-Albert networks with many initial neighbors

      Sumour, Muneer A.; Lima, Fws; Radwan, M. A.; Shabat, Mohammed M. (2015)
      The Barba'asi-Albert network [1, 2] is growing such that the probability of a new site to be connected to one of the already existing sites, is proportional to the number of previous connections to this already existing ...
    • Finite-size effects on semi-directed Barabási–Albert networks

      Radwan, M. A.; Sumour, Muneer A.; Elbitar, AM; Shabat, Mohammed M.; Lima, Fws (World Scientific Publishing Company, 2016)
      In scale-free Barabási–Albert (BA) networks, we study the finite-size effect at different number m of neighbors. So, we investigate the effects of finite network size N for the recently developed semi-directed BA networks ...

      Highly Nonlinear Ising Model and Social Segregation

      Shabat, Mohammed M.; Radwan, M. A.; Sumour, M. A. (الجامعة الإسلامية - غزة, 2012)
      The usual interaction energy of the random field Ising model in statistical physics is modified by complementing the random field by adding to the energy of the usual Ising model a nonlinear term , where S is the sum of ...

      Simulation of demographic change in Palestinian territories

      Sumour, Muneer A.; El-Astal, Ali H.; Shabat, Mohammed M.; Radwan, M. A. (World Scientific Publishing Company, 2007)
      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 fertility rates, leading to a significant increase ...

      Statistical physics applied to stone-age civilization

      Sumour, Muneer A.; Radwan, M. A.; Shabat, Mohammed M.; El-Astal, Ali H. (World Scientific Publishing Company, 2011)
      About 45000 years ago, symbolic and technological complexity of human artefacts increased drastically. Computer simulations of Powell, Shennan and Thomas (2009) explained it through an increase of the population density, ...

      STONE AGE CULTURE AND DIFFUSION IN ANNEALED RANDOM MEDIA

      Radwan, M. A.; Sumour, Muneer A.; El-Astal, Ali H.; Shabat, Mohammed M. (2013)
      Symbolic and technological complexity of human artifacts increased drastically around 45,000 years ago. Powell, Shennan and Thomas (2009) explained it using a computer simulation of a demographic model through an increase ...

      Urban segregation with cheap and expensive residences

      Sumour, Muneer A.; El-Astal, Ali H.; Radwan, M. A.; Shabat, Mohammed M. (World Scientific Publishing Company, 2008)
      In this paper we study urban segregation of two different communities A and B, rich and poor, distributed randomly on finite samples, to check cheap and expensive residences. For this purpose we avoid the complications of ...
