In the algorithm, the commercial finite element analysis （FEA） software is integrated as the calculating tool for analyzing the objective functions and the filter of Pareto solution set based on weight information is introduced to deal with the relationships among all objectives. Grid technology is utilized in PPGA to realize the distributed computations and the user interface is developed to realize the job submission and job management locally/remotely. Taking the aero-elastic tailoring of a composite wing for optimization as an example, a set of Pareto solutions are obtained for the decision-maker. The numerical results show that the aileron reversal problem can be solved by adding the limited skin weight in this system. The algorithm can be used to solve complicated topology optimization for composite structures in engineering and the computation efficiency can be improved greatly by using the grid platform that aggregates numerous idle resources.展开更多

In the era of ...In the process of education and teaching, the relationship between teachers and students is the most important one, which includes their position, role and treatment, mutual support and interdependence. In the era of scarce educational resources, teachers are the owners of knowledge. However, when the emergence of the Internet puts a huge amount of knowledge in front of people, what is scarce in education is no longer the amount of knowledge, but the selection, carding, promotion and internalization of knowledge. The traditional teaching method is transforming into learner centered individualized teaching and learning. In the process of teaching and learning, the proportion and focus of knowledge transfer and knowledge internalization have also changed. Under the new environment, teachers need to change the habits of teaching and learning for thousands of years, and carry out teaching in innovative mode through new technical means, so as to achieve higher results. However, in the new technology environment, if there is no complete teaching logic and the organic connection and cooperation between man and machine, classroom teaching will not present an orderly and efficient situation. If there is no good teaching design and the new educational technology is used freely, the teaching effect may not be as good as the traditional blackboard teaching mode.展开更多
