Correlation between the spatial heterogeneity and the collective motions of molecules is studied with molecular dynamics simulation of liquid water. Analyses based on the order parameter of structural fluctuations show that liquid water is a composite of high-density amorphous (HDA)-like regions...

We investigate the ordering kinetics due to the diffusion of adsorbates atoms on metal surfaces at several coverages and interactions corresponding to single phase region and two-phase coexistence regions. The kinetics is described by the mean field master equation in the context of lattice gas...

We study the unidirectional flow of mobile objects through obstacles on a square lattice. Two models are presented: one is the lattice gas model consisting of translational particles and the other is that of turning particles. Fundamental diagrams for the two models are presented. The traffic...

In this paper, the lattice gas model for pedestrian flow is extended to large maximum velocity vmax1. It is shown that at large vmax, the critical density corresponding to the maximum flow rate of fundamental diagram is in good agreement with empirical results. The counter flow is studied and it...

The aim of this paper is to examine thoroughly the dynamics of the diffusion process of mobile particles with repulsive interactions in inhomogeneou systems, and in the intercalation compounds such as LixTiS2 which presents a triangular structure. The study is done by using the lattice gas model...

Counterflow of students going on all fours is investigated by experiment and simulation. The experiment is performed for the channel with open boundaries. Two types of students going to the right and to the left are taken into account. The video recordings and measurements of individual arrival...

In this paper, evacuation dynamics in an office building is studied by experiment and simulation. A lattice gas (LG) model is developed. A parameter called ‘exit bias’ is introduced into the model to describe the occupants’ familiarity with different exits in a building. The evacuation...

We study the early-time morphology and the scaling behavior of the interfaces generated by the deposition, diffusion and aggregation processes. The description of the kinetics is based on the mean field master equation in terms of lattice gas model. The results show that the islands morphology...

We present a mobile lattice gas model for simulating the pedestrian evacuation process in a public building, through combining the advantages of the lattice gas model and the social force model. In our model, the interaction force between every two pedestrians and that between a pedestrian and...

We study the counter flow of slender particles on square lattice under periodic boundaries. Two types of particles going to the right and to the left are taken into account, where the size of right particles is larger than that of left particles. The counter flow of slender particles with...
