In order to study the damage on weapon equipment by explosive shock wave, simulation experiments were carried out to research explosive impact damage on stiffened cantilever box girder. Data mining method of PCA was introduced to process the damage data in simulation experiments. Basing on simulation and data mining, it discussed multi-objective optimization of stiffened cantilever box girder about...
In order to research the damage on weapon equipment by explosive shock wave, simulation experiments were carried out to study explosive impact damage on cantilever box girder. By using principal component analysis (PCA), it presented a data mining method on cantilever box girder damage. It showed that: the calculating result by using this method was agreeable with the result by using traditional method...
In this paper, product structure is taken as knowledge acquisition point, and the effective knowledge acquisition path is discussed by establishing the associated relationship between design demands of different design stages and corresponding product structure. The establishing method is to integrate rough set and artificial neural network (ANN). Design demands are reduced so as to form effective...
There is an increasingly concern with the use of retrospective power. Some researchers suggested calculating the retrospective power after conducting hypothesis testing, particularly in meta-analysis. They considered that retrospective power can be used to determine whether the sample size is sufficient in an experiment and that the combination of retrospective power and prior power can enhance the...
