The paper is concerned with the problem of input-to-state stability (ISS) for a class of systems with large delay period (LDP). The concepts of the length rate of LDP and the frequency of LDP are introduced. First the considered system is converted into a switched delay system which may include an unstable subsystem. Then based on a piecewise Lyapunov functional, the ISS conditions of the systems...
Eddy current testing is an important and widely used method in non-destructive testing and evaluation. In this paper, an impedance analysis model of eddy current testing based on mutual inductance equivalent circuit is established using transmission line theory, and an analytical expression of impedance of the testing workpiece is obtained. Then the changes of impedance plane of ECT sensor affected...
The asset-liability ratio level of most companies in China is on the high side, even the companies with very excellent capital structure, they have higher asset-liability ratio level than their foreign counterparts. In view of bank loans is still the mainly debt financing ways of company in China, this article study the conflicts and countermeasures of debt financing between the listed companies and...
With the rapid momentum of high and new technology industry, e-government system have found a wide construction in all walks of life, to heighten the management level, and the education profession is no exception. This paper aims at deeply expounding the necessity of enhancing the construction of e-government on campus and exploring the way to enhance the construction of e-government, based on analyzing...
The temperature has violent influence on the test accuracy on the moisture content of crude oil by microwave. Establishing the affection of temperature, especially high temperature, plays an important role in improving the accuracy of detection. Indoor equipment of testing moisture content of oil-water mixture by microwave was built, which fulfill the test conditions with temperature 20°C-200°C and...
Party construction of college students, as the core of building morality education system under the new situation, is the most effective way to strengthen the ideological and political work of students comprehensively. This paper makes in-depth research on effectiveness of improving college Party construction, and analyzes problems in the construction in detail. In addition, this paper studies the...
In order to compress calculation, the background estimation algorithm for the infrared target detection was proposed. Firstly, a Least Square Matrix is proposed and an image background is estimated. Then the target is detected by self-adaptive threshold detection in different images. It is shown by nonlinear function regression experiment and sequence infrared image detection experiment whose methods...
Applying data gained from questionnaire, through T Test for Independent Samples, one-way ANOVA and Pearson correlation analysis, the paper analyzed the influences of eight chosen factors on perceived risk by consumers in online shopping. This empirical study finds that friend recommendation, Internet purchasing experience and involvement have significantly negative effect on financial risk and overall...
Bilingual teaching has been carried out for a few years in our college, especially in order to adapt to the new situation recently, the bilingual education must be highlighted. In order to promote developing and improving the work, the pros and cons of bilingual teaching were stated, combining with the authors' experience, as case of Ecology. The purpose was to develop the advantages and eliminate...
This paper designs a novel wireless surveillance system in greenhouse, in order to solve long-existing problems in traditional systems, such as high maintenance cost, low robustness and mobility, etc. We firstly introduce the system architecture, with hardware structure defined and carefully designed on sensor, then we proposed the wireless communication protocol including transmission and data format...
Recently, periodic pattern mining from time series data has been studied extensively. Existing studies on periodic patterns mining mainly consider discovering full periodic patterns from an entire time series. However, partial periodic patterns are more useful in practice since only some of the time episodes may exhibit periodic patterns. This paper aims to discover the partial periodic pattern in...
Distribution systempsilas management was based on the management of point, line, surface objection on the area. There were figure data and attribution data in this management which form GIS with special space in-fighting. The paper adopted SuperMap2000 and VB as developing tools, explored designing scheme, developing process and overall function designing of rural power enterprises' distribution system...
