Difficulties and Countermeasures for Machine Understanding of Chinese: A Viewpoint of the Sense-group Dynamics;

The paper discusses engineering calculation of evacuation time based on crowd dynamics,in order to correct the error and give some improvement to the existing calculation method a comprehensive calculation method is given,in which pre-movement factor and interaction factor are introduced.

From the viewpoint of colony dynamics,Hi-tech enterprises do allow or even creat the subdirections of development which deviate from the basic direction;creat more space of development for colony of high quality human resources.

In this paper,we have studied a SIS epidemiological model with a nonlinear incidence rate and population dynamics in susceptible class.

In order to investigate the relation that host and phage depend on and compete with each other,we propose a novel model of host-phage population dynamics that accounts for the decreased ability of phages to lyse hosts as hosts approach their carrying capacity.

Based on both the population dynamics model and the continuous variety of thermo-physical parameters, supersaturation and nucleation rate, a model was developed to describe the microstructure evolution of hypereutectic Al-Si alloy during rapid solidification, and was solved for A390 alloy.

A model has been developed to describe the solidification kinetics of the gas-atomized alloy droplets during spray forming based on the population dynamics method.

To study evolution of different population which consists of individuals with distinct skill,a simple model of population evolution is proposed,which depicts population dynamics involving individual\'s life characteristics,such as reproduction,mutation,and death.
