Mathematical Modeling of Urban Population Changes Essay

Mathematical Modeling of Urban Population Changes Background of Issue The growth of population is the issue that caused widespread concern in the world now. As the world’s top 1 populous country, China’s population problem becoming more prominent. Because of the base of large population, although China has implemented the one-child policy to practice family planning, population is still increasing greatly. This huge population pressure has brought a series of problems on China’s social, political, economic, health, employment, etc. therefore, research and solve the population problem is particularity important for China.

Mathematical modeling has emerged as an important tool for gaining understanding of the dynamics of the spread of infectious diseases. The need of accurate models describing the epidemic process are vital, because infectious diseases outbreaks disturb the host population and has ï ¬ nancial and health consequences. There is also the need to use sound statistical analysis methods to testRead MoreDiscuss the Impact of the Automobile’s Rise on Urban Form During the Twentieth Century and Critically Evaluate Planning Measures Used to Limit the Negative Social and Environmental Aspects1691 Words   |  7 Pagesautomobile’s rise on urban form during the twentieth century and critically evaluate planning measures used to limit the negative social and environmental aspects Since the rise of the automobile, there have been many dramatic changes to urban form in attempts to accommodate this new mode of transport.
