In order to improve the accuracy of damage detection result and increase the computational efficiency, a new method for structural damage detection based on the perturbation of frequency and improved residual force vector (IRFV) was studied. The equation of structural damage identification based on the changes of frequency was derived from matrix perturbation theory. And the differences of residual...
This paper presents an expanding products algorithm of logic optimization that is based on multi-input multi-output logic functions. According to input products, we work out complement sets matrix of non-shared products, blocking matrix, covering matrix. For blocking matrix and covering matrix, we get mini column cover sets and upgrade sets based on choice algorithm of mini column cover. Then we form...
In solving the decision-making problems of complex multi-index evaluating scheme, the traditional way is to adopt fuzzy unified evaluating method. But the traditional fuzzy evaluating method has a lot of shortcomings, e.g. being unable to fully reflect the intended purpose of fuzzy evaluation, because it is difficult for experts to score an evaluating index definitely; sometimes hardly providing a...
