A web-based computer-aided material-selection system for aircraft design, together with its architecture and implementation details, is put forward. Furthermore, a prototype of this system is developed and the prototype’s effectiveness is demonstrated by an aircraft-design material-selection case in actual applications. This system can help designer(More)
In this paper, we consider there exist two types of fundamental quasihole excitation in the fractional quantum spin Hall state and investigate their topological properties by both Chern-Simons field theory and the Berry phase technique. By the two different techniques, we obtain the identical charge and statistical angle for each type of quasihole, as well(More)
A new material selection approach based on PROMETHEE method is proposed in this paper. Compared with ELECTRE method, this PROMETHEE can utilize more candidate information, thus making the selection result more reasonable. The approach is further illustrated and validated by two material selection cases. And Spearman's rank correlation coefficient is used to(More)
