Research on the General and Professional Integrated Education at Universities under the Background of Engineering Education Accred­itation

Under the background of“Engineering Education Accreditation”,it is of great significance to carry out the general and professional integrated education at universities.This paper discusses the epoch connotation of general education at universities and the necessity of developing general education in the professional courses of the universities.The conceptual characteristics,practice modes and ways of carrying out the general and professional integrated education at universities under the background of Engineering Education Accreditation are discussed.Finally,an example is given to verify the feasibility and implementation effect of carrying out general education in professional courses of university,so as to provide references for the development of the general and professional integrated education at universities in the new era.

On the Conditions of a Center and General Integrals of Quadratic Differential Systems

We give the general integral of quadratic differential system with center in two cases under the Chinese classification.

General Convex Integral Control

In this paper, a fire-new general integral control, named general convex integral control, is proposed. It is derived by defining a nonlinear function set to form the integral control action and educe a new convex function gain integrator, introducing the partial derivative of Lyapunov function into the integrator and resorting to a general strategy to transform ordinary control into general integral control. By using Lyapunov method along with the LaSalle s invariance principle, the theorem to ensure regionally as well as semi-globally asymptotic stability is established only by some bounded information. Moreover, the lemma to ensure the integrator output to be bounded in the time domain is proposed. The highlight point of this integral control strategy is that the integral control action seems to be infinity, but it factually is finite in the time domain. Therefore, a simple and ingenious method to design the general integral control is founded. Simulation results showed that under the normal and perturbed cases, the optimum response in the whole control domain of interest can all be achieved by a set of control gains, even under the case that the payload is changed abruptly.

Persist in and Carry Forward the Integrative Medical Research——Speech at the 6th National General Congress of Chinese Association of Integrative Medicine by Academician CHEN Zhu,Minister of Ministry of Health

The 6th National General Congress of Chinese Association of Integrative Medicine （CALM） was convened at 19-20, April 2008 in Beijing. Academician CHEN Zhu, the minister of Ministry of Health indicated at the congress that the integration of Chinese and Western medicine is very well in keeping with the situation of our country and the general rule of development in medical science; and as a good integration of Chinese medicine and Western medicine, it is mutually beneficial and advantageous to both of them. Seeing the creativity shown in integrative medical investigation in theoretic and methodological sides, we should and must persist in and develop it.

A multi-scale architecture for multi-scale simulation and its application to gas-solid flows

A multi-scale hardware and software architecture implementing the EMMS （energy-minimization multi-scale） paradigm is proven to be effective in the simulation of a two-dimensional gas-solid suspension. General purpose CPUs are employed for macro-scale control and optimization, and many integrated cores （MlCs） operating in multiple-instruction multiple-data mode are used for a molecular dynamics simulation of the solid particles at the meso-scale. Many cores operating in single-instruction multiple- data mode, such as general purpose graphics processing units （GPGPUs）, are employed for direct numerical simulation of the fluid flow at the micro-scale using the lattice Boltzmann method. This architecture is also expected to be efficient for the multi-scale simulation of other comolex systems.
