In this paper, K-means clustering algorithm is applied to the classification of college students, by which studies college students’ organization form and then discovers new college students’ organization from. By means of defining students’ attributes, the whole text quantities and normalizes those...

In order to obtain the response of nonlinear structural dynamic system effectively, a linear, time-varying approximation method is proposed in this paper. The technique is based on the replacement of the original nonlinear system by a sequence of linear time-varying systems, whose solutions will converge...

According to the exact three-dimensional (3D) thermal theory, the steady temperature distribution in a laminated rectangular plate with zero temperature conditions on four lateral surfaces was studied. An analytical method was developed to solve the temperature field in the plate. Firstly, the general...

Carbon Fiber Reinforced Plastic (CFRP) is an important material to make aircraft structure components. However, damage detection is very crucial to aircraft safety and the type of a detected defect is difficult to distinguish. Ultrasonic phased array (UPA) technology provides a possible solution. In...

Molodtsov first proposed the soft set theory, which can be used as a general mathematical tool for dealing with fuzzy and uncertain information. As a generalization of soft set, interval-valued intuitionistic fuzzy soft set is another soft set structure,it is a combination of an interval-valued intuitionistic...

Kong. et al. (2014) [1] presented an efficient approach which gives weighted-average of all possible choice values of soft sets under incomplete information system, However, the weights of the attributes are not considered, although all the entries are “1”, the importance of all attributes are not all...

Hadoop is a wide applied tool for large-scale data-intensive computing in big data, but it can only be implemented on single cluster environment. In this paper, we focus on the application of Hadoop across multiple clusters and dedicate to solve the key problems of data sharing and task scheduling among...

It is a big challenge to get complete accurate information as well as deal with huge amount of signal information when an ultrasonic phased array (UPA) instrument is used to test aircraft components. To solve this problem, a method that combined information fusion technology with Graphic Processing Unit...

We first establish the relationship between the grid cell connectivity matrix bandwidth and the efficiency of parallel computing, which shows that parallel efficiency can be improved by reducing the bandwidth so that the external communication is reduced. An algorithm based on the AD algorithm is developed...
