In recent years, China has adhered to the concept of sustainable development respecting nature, protecting nature and living in harmony with nature. A typical example is China’s long-term ecological management Saihanba. Since 1962, after more than half a century rescue, established world’s largest artificial forest, improving environment Saihanba area, making lungs surrounding cities (Beijing, ...

In order to improve the evaluation precision of education and training quality, a kind of quality evaluation model of combined medical education and training course (AHPPCASV) is put forward, which is a combination of analytic hierarchy process, principal component analysis and support vector machine. Firstly, AHP is used to construct the evaluation index body, and then the principal component ...

in the present study, quantitative relationships between molecular structure and anti-tubercular activity of some 5-methyl/trifluoromethoxy-1 h -indole-2,3-dione-3-thiosemicarbazone derivatives were discovered. the detailed application of an efficient linear method and principal component regression (pcr) for the evaluation of quantitative structure activity relationships of the studied compound...

Abstract This paper presents fitness evaluation functions that efficiently evolve coordination in large multi-component systems. In particular, we focus on evolving distributed control policies that are applicable to dynamic and stochastic environments. While it is appealing to evolve such policies directly for an entire system, the search space is prohibitively large in most cases to allow suc...

Evaluation is considered to be an important component of any creative process. This paper explores how evaluation can be incorporated into our minimal model of creativity, which we have been developing using a combination of conceptual analysis and evolutionary robotics. Specifically, we consider how to extend our approach so that the robots themselves can evaluate mark patterns that they, or o...

the main objective of this descriptive- suvey research was to analyze components of quality of e-learning in the iranian agricultural higher education. the statistical population of the study consisted of the graduate students of iranian agricultural colleges (n=8541), out of which 286 people determined as sample using cochran formula and proportionate stratified sampling technique. the data we...
