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...

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...

We study the behavior of walkers sidling through the crowd in the counter flow of pedestrian. When a walker enters the crowd, he turns himself sidelong to avoid a collision and edge through the crowd. The biased random walk model is extended to take into account the sidle effect. We present...

Evacuation processes of walkers (pedestrians) and crawlers are investigated by experiment and simulation. The experiments are performed for walkers and crawlers evacuating from the corridor (channel) with an exit. All students go on all fours in the evacuation experiment of crawlers. The video...

In this paper, the interaction between vehicle and pedestrians in the narrow channel is studied. Comparing with our previous work, here the vehicle is allowed to move with different maximum velocity. The pedestrians are stilled modelled by the lattice gas model and they are regarded as biased...
