Maximum system reliability of series-parallel system is depending on proper allocation of redundancy component in different stage. The goal of entropy based reliability redundancy allocation problem is to find optimal number of redundancy component in each stage such a manner that maximize the system reliability subject to available total system cost. Global criterion method is used to analyze entropy based reliability optimization problem with different weight function of objective functions. Numerical examples have been provided to illustrate the model.展开更多

The students in the control group were examined with the traditional assessment method, namely, the points were given the students one-time and estimated in a way of quantitative analysis. The students in the experimental group were examined with criterion-meeting assessment methods. The average score of students in the experimental group was higher than that in the control group (P <0.001), the difference was statistically significant, and 100% students in the experimental group got 90-100 points of the assessment standards. Our studies suggest that the method is not only conducive to fully mobilizing the enthusiasm of the students and students’ establishing critical thinking, but also gives help to improve the overall quality of teachers. It can strengthen the experimental teaching, improve teachers’ and students’ senses of responsibility in teaching and learning and contribute to the good teaching result.展开更多

Therefore it is important to analysis the micro-rotation field in a strained material in fractute mechanics. On the basis of strain-rotation (S-R) decomposition theorem, the geometric criterion of cracking has been established. In order to verify its validity, using grating experimental method the thin compact tension specimens were investigated. The analysis results show a good agreement between the experimental and geometric criterion.展开更多

The reliability of the function is also analyzed. The results show that this criterion works well and has a global feature, which can be used as first-level filtering criterions in event identification. The quantitative and linear discrimination function makes it possible to identify events automatically and achieve the goal to react the events quickly and effectively.展开更多
