At low frequencies, the solution of Maxwell's equations breaks down. To overcome this problem, in this paper, a new method is proposed, which is using multi scale analysis method. A synthesis is made of the input impedance of power lines. The results are compared with the analytic solutions, and they are anastomosed. It proves that this method can solve more issues at low frequency.
Asymptotic stabilization problem is investigated for a class of complex dynamical networks with the time-varying coupling configuration matrix and different nonlinear nodes. Firstly, a general time-varying complex dynamical network model with different nonlinear nodes and nonlinearly coupled functions is proposed. The time-varying outer coupling matrix in this paper is only needed to be dissipatively...
Thanks to their advantages, such as high storage density and short response time to customers' requests, puzzle-based compact storage systems have been increasingly installed in warehouses and distribution centers recently. This study addresses zone boundary optimization for puzzle-based compact storage systems when a three-class-based storage policy is implemented, in attempting to facilitate system...
In order to reduce the unnecessary material and the time consumed, and to improve design efficiency in the actual prosthetics physical prototype design process, this paper uses virtual technology to build a simulation system. First, Adams software is used to create a virtual humanoid robot model with 14 degrees of freedom; second, a virtual bionic hand's fuzzy PID control system is built based on...
Ellipse is an important feature curve usually used in image analysis, computer graphics and computer aided geometric design. In this paper, we propose a new ellipse fitting method using data normalization. Prior to the ellipse fitting, a linear normalization transformation is used to preprocess the original data. The normalization transformation can increase the computation stability in solving the...
In this paper, fuzzy comprehensive evaluation and Matlab combining method is applied to the assessment of cadres, the first divided into four categories based on attributes in each category was divided into four categories, first in the various factors in the implementation of a single judge, and then together to implement a secondary evaluation, and finally given the realization of the Matlab model...
To identify the fittest quantity for every higher education resources in Heilongjiang province, a surface model is constructed based on collected data in 20 years, 15 vectors and the corresponding multinomial equation. Firstly, the vectors are integrated to human capital, material capital, intellectual capital and intangible capital, which have been reconstructed from the original data. Considering...
