Recently we developed a stochastic particle system describing local interactions between cyanobacteria. We focused on the common freshwater cyanobacteria Synechocystis sp., which are coccoidal bacteria that utilize group dynamics to move toward a light source, a motion referred to as phototaxis. We were particularly interested in the local interactions between cells that were located in low to ...

In this work, the thermal reaction of aluminum (Al) and nickel oxide (NiO) was investigated by molecular dynamics simulations. Some effective features of reaction such as reaction temperature, the reaction mechanism, and diffusion rate of oxygen into aluminum structure were studied. ReaxFF force field was performed to study the Al/NiO thermite reaction behavior at five different temperatures (5...

Theoretical explanations of group offending have been hindered by a focus on rational actor models social relationships. One consequence this has neglect the dynamics relations and their role in desistance. Drawing illustratively two studies conducted West Scotland, article advances an integrated theoretical framework for comparative study that moves beyond either individualizing or ‘gang’ fram...

Abstract This paper investigates a new method to simulate pedestrian crowd movement in large and complex virtual environment, representing public space such as shopping mall. To demonstrate dynamics, we consider groups of pedestrians different size, sharing crowded environment. A has its own characteristics, gender , age position velocity energy . The proposed uses multi-group microscopic model...
