This paper deals with the boundary stabilization problem for the FitzHugh-Nagumo system, which is a coupled system of a non-linear diffusion partial differential equation (PDE) and an ordinary differential equation (ODE). Using the backstepping transformation and a boundary feedback controller, the original unstable system can be converted into a nonlinear target system, from which the stability analysis...
Under the background of Financial Crisis, it is very important to make use of the governmental investment and state policy to incentive private investment, arousing folk capital and making people living rich, so as to expand domestic demand and promote China's economic development healthy, steady and rapidly? Whether the government's “four trillion economic plan” has produced crowd-out effect on private...
Rooting process of wheat was modeled in use of Linden Mayer system in the present study. Rooting rules along with growth cycle were concluded based on topology and biology analysis, in which the seminal roots and crown roots were treated separately. Meanwhile, some easy-to-use key parameters which are agronomical meaningful were proposed, including time, size, orientation and so on. After these preparations,...
Prisoner's Dilemma, which is a basic model adopted by the vast majority of co-evolution researchers, not only is a classic paradigm for studying co-evolution but also is a classic paradigm of modern business management for researching the enterprises, between which there is competition and cooperation. In this paper, a dynamic model of spatial continuous Prisoner's Dilemma (CPD) will be suggested,...
Considering the asymmetry of return distributions and asymmetric impact of positive and negative returns on the quantiles, the paper puts forth a new conditional autoregressive value-at-risk by regression quantiles model with asymmetric absolute values and slops (AAVS-CAViaR) quantile specification for heavy-tail data applications. An empirical study on the evolution patterns of market risk of wheat...
Pick-up and set-out trains refer to these trains marshaled in technological station, serving for vehicles flow in the district, whose pick-up and set-out operations are done in intermediate stations in the district. Running of limiting speed pick-up and set-out trains has an impair on railway transport capacity and research on railway transport capacity loss mechanism for limiting speed pick-up and...
Recent years, nonstandard employment, special the nonstandard employing knowledge workers, has been coming an important method for organization to increase its flexible ability and competitive ability. However present literature show confusing results about its effectiveness, some show good effectiveness, and some show bad. Firstly this paper analyzes the nonstandard employing knowledge workers' effectiveness...
Statistic analyses were made based on the daily air pollution index data at five cities in Xinjiang of northwest of China from January 2005 to October 2008. Trajectory model (HYSPLIT4.8) was used to analysis the backward and forward trajectories on heavy air pollution days during winter of 2006. The results presented as following. 1) Winter is the season with the highest occurrence frequency of air...
This dissertation tested whether the relationship between systematic risk and average returns of financial stocks in China consists with the CAPM(capital asset pricing model) theory, using the daily data of 2007 and comparing the method ordinary least square(OLS) with quantile regression. The result shows that, systematic risk is not the only determinant factor of financial stockspsila pricing in...
