Based on the financial security index calculated in the method of principal component analysis, this paper applies the model of BP neural network to test the result and then puts forward the early warning of Chinese financial security position in the future. In addition, the article gives some following suggestions for the early warning of financial risks: we shall reform the current financial regulation...
Based on the transfer data from 2009 to 2014 of the A Bank in Yiwu city (the largest bank in the local), this article construct the industrial network of Yiwu City by using complex network research method; then in this paper, it selects manufacturing industries in Yiwu city as a sample and analyzes the non — linear relationship between industrial network structure and industrial growth with the modified...
In existing recommendation systems, there exist the issues of “cold start” and “excessively mature recommendation,” which cause the recommendation systems to have weak effectiveness; thus, a trust-based recommendation model with a small recommendation probability for unknown items (RM-UI) is proposed for social networks. In the RM-UI scheme, the recommendation values of items are primarily derived...
Planning and construction of charge stations are important aspects of promoting the development of electric vehicles (EVs). Integrated with the equilibrium traffic flow, a comprehensive optimization strategy aiming at achieving siting and sizing planning of charging stations on the road network is presented in this paper. The system optimization model is used for generating and assigning the equilibrium...
Nowadays, the development of traction motors of high speed train require highly to the bearing's performance. Magnetic-fluid bearing, as a new kind bearing with so many advantages we need, has got lots of attention. And the key problems of Magnetic-fluid bearing are lubrication and reliability. In this paper, we focus on the temperature field problems which influence the lubrication performance as...
Active deception jamming Scenario generation technique to SAR plays an important role in the development of SAR system and the evaluation of anti-jamming ability. Research on active deception jamming scenario generation technique to SAR is simple now. SAR jamming scenario echo simulation is studied aimed at the problem, through analyzing the basic principle of SAR and deducing the mathematic model...
The R&D of aviation complex products new technology is an important component to realize the strategy of building an innovative country, it plays a decisive role in improving national competitiveness, but because of the high risks in new technology research and development (R&D) of aviation complex products, the new technology of aviation complex products could be realized only through comprehensive...
Considering the network-induced delay existed in the network control systems, a simple simulation is required firstly to understand the effect of network-induced delay on system performance, the delay is inevitable, which can degrade the performance of control system and even destabilize the system, so it is necessary for us to study this problem. Secondly, the modeling of networked control systems...
In this paper, dicing saw process on the wafer has thick Aluminum pads on the scribe street is studied. Thick Aluminum pads wafer has bad topside chipping at Aluminum pads and the chipping out of specification limit is about 3.0%. New blade and dicing saw process are introduced to solve this issue. According the evaluation results, optimized recipe can solve the bad topside chipping on the Aluminum...
A method of fault location is presented which is based on the traveling-wave scheme for rural MV power networks. There are two steps in this method, the first step is to determine the fault section, and the second is to find the fault point. When a single-phase-to-earth fault happened, injecting a narrow pulse signal with high voltage and detecting the wave signal returned back from the line, we analyze...
