高校宣传工作在新农村建设中的主体作用

建设社会主义新农村在今后很长时期内都是全党工作的重中之重。高校宣传思想工作是党和人民的喉舌,具有鲜明的党性,在新农村建设中要以科学的理论武装人,要以正确的舆论引导人,以高尚的精神塑造人,以优秀的作品鼓舞人,充分发挥新闻宣传工作宣传、教育、激励、动员的作用,统一思想、凝聚力量、促进发展、为新农村建设服好务。

Thermal optimization of a totally enclosed forced ventilated permanentmagnet traction motor using lumped parameter and partial computational fluid dynamics modeling

In this study, we present a thermal optimization method using the overall lumped parameter (LP) and partial computational fluid dynamics (CFD) modeling for a 600-kW permanent magnet traction motor developed for high-speed trains. The motor is totally enclosed forced ventilated to achieve high power density, high efficiency, and low maintenance requirements. Considering the electro-magnetic performance, bogie space, and thermal capacity, we propose a ventilation structure with zigzag plates in sector cross-section. We focus particularly on the ventilation channels and propose an overall LP model for thermal optimization, in which the full consideration of the influence of turbulent flow is given by using a partial CFD model. Given the specific critical parameters from the optimization results, we present a complete 3D CFD model of the whole motor to obtain an accurate temperature distribution and the maximum temperature rises in local points. The benefit of zigzag plates is studied extensively using both the LP and the complete CFD models and the results are verified by equivalent thermal experiments under rated operations. Experimental results indicate that the ventilation structure fulfills the normal operational demands of high-speed trains by improving thermal performance by more than 15%. Additionally, we propose an engineering method to estimate iron loss constraint with the complete CFD model to guide the control system design.

The aim of this paper is to provide an introduction to higher mathematical concepts and techniques as applied to real-world problems. An interesting case study is the 200-mile limit for fisheries presented in Wan (1989, Mathematical Models and their Analysis (New York: Harper and Row)). It is commented upon, re-examined and solved in a different manner inspired by Turing's (1952, Philosophical Transactions of the Royal Society London , B237 , 37-72) paper as a suitable classroom example for undergraduate students taking a first course on mathematical modelling. Emphasis is made not only on the mathematics--always kept as elementary as possible--but also on interpretations, explanations and translation into plain language of the mathematical expressions and results.

Analysis of FIFA referees and assistant referees’ motivational factors towards the Multimedia Teaching Materials

The aim of our study is to improve the understanding of the different behavioral intentions of referees and assistant referees in different FIFA (International Federation of Association Football) confederations towards Multimedia Teaching Materials as learning tools. To achieve this goal, we carry out a survey of 214 elite referees and assistant referees and we propose a research model with the variables perceived usefulness, perceived ease of use, perceived enjoyment, perceived self-efficacy, multimedia instruction, previous experience with technology and self-paced learning. These variables were taken from previous educational technology research. Among these models we mainly take into account the Technology Acceptance Model, the Motivational Model and the Social Cognitive Theory. To assess the relationships between the constructs, we develop an analysis based on a Structural Equation Modeling (SEM), specifically Partial Least Squares (PLS). The results of this study confirm that referees and assistant referees are willing to use Multimedia Teaching Materials to assist them in their learning activities as long as they perceive the materials to be useful, enjoyable and easy to use and whenever the course contents are multimedia.
