The partner selection and optimization problem is an important area of virtual enterprise (VE). Genetic algorithm (GA) is optimization and parallel strategy simulating biology evolutionary mechanism in nature and a high efficient algorithm solving these types of problems. After analyzing the partner selection problems of virtual enterprise, the improved genetic algorithm (IGA) was presented to solve...
In recent years, modern logistics develops rapidly as a whole. To the logistics industry in China, compared with the international lack of understanding from the comparison of domestic and international logistics development, Especially in Beijing city logistics domestic only big cities including Shanghai, has some development to develop city logistics city logistics business development of small...
Electrical Explosion of thin metal wire has many important applications such as wire array load in Z-pinch, synthesis of nanometer powder, generation of shock wave, et al. The explosion plasma has crucial significance in these applications1,2. Plasma characteristics of the explosion plasma is powerful method to study basic process of electrical explosion of wire. In this paper, the explosion plasma...
In this paper we present a result which modifies Moreau's theorem [1] on linear consensus problem over time-varying directed networks. Our result uses integral connectivity on varying-length intervals to characterize the consensus criterion and conditionally allows the Laplacian matrix to be unbounded. Some examples are given to show the details of the result.
In the paper, the authors proposed the concept of patient satisfaction degree and established some factors that affect patient satisfaction degree according to the research on the spot in the concrete hospitals and systemic analysis. Firstly, it took ten hospitals in the 14 three A-level hospitals as examples in random, and handed out the questionnaires of patient satisfaction degree. Then the paper...
Science education models for secondary students have been dominated by classroom-based approaches. Recently, the student scientist apprenticeship model wherein learners worked with teachers on authentic scientific research has become increasingly popular. The purpose of this paper was to review and synthesize empirical studies that have explored learning outcomes associated with the student scientist...
Just as computer technology has improved effectiveness in numerous sectors of society, advanced computing and telecommunications have the potential to help students master complex 21st century skills. An Integrated curriculum is developing technologies that enable students use advanced tools to solve real world problems. The integrated curriculum approach improves success for all types of learners...
A kind of attribute reduction algorithm of Jiahua Lu was firstly introduced and its performance was analyzed briefly, then aimed to its improvable points, a new attribute reduction algorithm based on the binary discernibility matrix and an improved attribute importance function that utilized the potential information of the information system, which considered attributespsila occurrence number and...
In this paper, we propose an auto-decision system KMCD, which helps remote students choose their majors. The system is based on knowledge of students who want to choose majors and students who have finished their studies. KMCD is a first-order reasoning system equipped with an uncertain reasoning function. A description of KMCD is given in details. The whole decision procedure is comprehensively discussed,...
