It is established that population structure prediction time-varying restriction system model, and its controllability of the system is analyzed through grey system theory and control theory. Based on Liapunov central limit theorem, the conclusion that child-bearing age of women is subject to the normal distribution is obtained, and the density function of fertility age is given. Fertility restricted...
Child obesity is a public health problem that is of concern of several countries around the world. Long-term effects of child obesity include prevalence of chronic diseases, such as diabetes and heart-related illnesses. This paper presents an agent-based simulation framework to analyze the evolution of obesity in school-age children. In particular, in this paper we evaluate the impact of physical...
In the past two decades, under the double impact of the increasing numbers of universities and the falling birth rate, the enrollment drops have struck many universities. Plus, the lower birth rate results in the impact of universities' enrollment shortfall. Based on the questions above, the paper proposes the method to find the reasons of the main impact factor. First, we collect the factors of total...
Although the potential benefits of using digital video in educational settings is well researched, little work has been conducted into how video modelling and messaging technologies can be devised and implemented to support teaching in educational settings. Video is generally used as a "passive medium " whereby students watch a video presentation to ascertain information. In this paper we...
Pattern Oriented Modeling (POM) is an approach to bottom-up complex system analysis which was developed in ecology and for agent-based complex systems. This paper proposes a pattern-oriented agent-based simulation (POABS) approach to analyze agent-based complex system. We apply POABS to a history simulation domain to analyze a particular family line with more successful candidates in the civil service...
