Music education for children has a strong appeal, most likely to cause the resonance of children, children accept education is the earliest feelings of music, and music education has quite an effect on children's intelligence development of speech. With the rapid development of science and technology,...

In this article,we take the Kariba Dam as an example and analyze the number and location of new small dams in detail through Exponential estimation method and Gray Analytic Hierarchy Process. Then,we set up a model and put forward the concrete strategy of regulating water flow. We firstly make a simple...

Phonetic experiments with Kazak words including vowel /e/ in different positions were undertaken, and formant values of the onset point and the offset point of the sounding process of each /e/ have been extracted and analyzed. The results and finding indicate that vowel /e/ in Kazak is not a diphthong...

The rapid development of society and economy has put forward higher and more diversified requirements for the cultivation of higher talents. This urgently needs that colleges and universities adopt effective reform measures to further deepen the teaching reform, adjust the teaching contents in time,...

Based on the data of a arch bridge that lready built up, the finite element analysis model is established by finite element analysis software called Midas Civil. The buckling mode and buckling characteristics of the bridge are analyzed. The following operations changes are performed: the width of the...

In many industrial fields, there always exists mechanical regular movements, for example, the movements of reciprocating pumps in an oil field, which brings limitation for the detection. The tranditional methods including background subtraction cannot be used directly. In order to fit the scene with...

There are many different kinds of machine element, with professional development of industrial production, only a few machine elements needed by factories are for their own production, most are needed to be purchased. Using purchase quotation system for machine element is an effective mean to ensure...

Numerical simulation has significant advantage in analyzing the interaction between rigid wheel and lunar soil simulants and designing the lunar vehicle wheel under complex circumstances. The computer aided design software CATIA and 3D Discrete Element Method simulation software PFC3D were combined by...

The rapid development of the Internet and the rapid spread of information technology accelerate the process of economic information and economic globalization, competition has changed the traditional business model. More and more enterprises are developing an online retail business. E-commerce model,...

Metallic ceramic materials while maintaining the excellent properties of ceramic materials, but also have the advantages of a metal material, is an important new engineering materials. Iron-based composite applications broad, but not high abrasion resistance, wear-resistant engineering parts for such...

Online learning is a learning way to use online education platform for learners. It could let the learners start learning at anytime from anywhere by removing the traditional education's time and space limit. As the online learning style becomes more and more popular, its main base environment has gradually...

Aiming at characteristics of wisdom scenic, based on semantics Internet of things technology, we have realized a kind of scenic intelligent information service system which integrates various functions including scenic guide, environmental information perception, etc in one, designed system architecture...

The automation and intelligence of the overhaul technology are related to the level of the whole substation automation and intelligence. Aiming at the problems of low automation level of substation high-voltage equipment overhaul, this paper mainly studies robot-based live overhaul technology. The design...

Traditional phase detection methods of weak signals have some problems such as high complexity and low accuracy. To cope with these problems,, this paper proposes one novel parallel detection algorithm based on multi-coupled oscillators. Firstly, the chaotic detection model and double coupled oscillator...

For power system real-time data capacity is large, and the actual storage space is limited. This paper proposes a real-time data compression method based on wavelet transform. This method compress and decompress real-time data in power system through compactly supported orthonormal wavelet. The results...

Tungsten (W) commonly serves as the electrode layer or acoustic reflector layer for the highly columnar growth of AlN piezoelectric thin films used to fabricate film bulk acoustic resonators in power applications. The structure of W film directly influences the texture of AlN thin films above. Moreover,...

Based on OpenGL and Google library we established the target model library and the canny operator is used for edge detection. Combined with D-S evidence theory and Pseudo-Zernike moments, the air target recognition algorithm based on information fusion is proposed. Pseudo-Zernike moments are invariant...

Based on low frequency load-shedding practice experiments of Xinyang power supply company, work principles as 'three reports, one examination and a table modification' is proposed to improve the management of power grid in substitute district. The methods introduced in the paper is proved to be effective...

Basing on scene analysis and VaR calculation, this paper discussed system architecture of scenario calculation and accurate data's importance of system model from the view of system theory. We also discussed several kinds of data errors and their processing methods to avoid the error of data. Then we...

This paper takes the University-enterprise cooperation of the biological science major of Lüliang University as an example. Through the questionnaire survey and interviews with relevant personnel, we can comprehensively investigate the situation of University-enterprise cooperation in Lüliang University....

This paper analyzes the social resources embedded in practical teaching and its impact on undergraduate employment, in order to provide guidance for solving the problem of "employment difficulties" caused by the disconnection between classroom teaching and enterprise needs. Firstly, social resources...

This paper uses the factor analysis method to measure the degree of polarization of innovation resources in China. The results show that between 1997 and 2016, the degree of polarization of innovation resources in China has generally shown an upward trend, that is, the flow of regional innovation resources...

Innovative resources are concentrated from the surrounding backward areas to the economic center, thus forming an innovative polarization effect. As the growth poles appear to the surrounding areas, the polarization effect transitions to the diffusion effect. This paper uses the factor analysis method...
