Recently, the sparse representation-based classification (SRC) is getting more and more attention in many fields, such as pattern classification, which has been successfully applied to face recognition. However, the essence of SRC, within face recognition, is to use the linear combination in the same...

Eu3+ doped bismuth silicate phosphors, Bi4Si3O12:xEu3+ (0.01 x 0.08) were prepared via sol-gel route. XRD results show the phase of the synthesized phosphors calcinated at 650 is isostructural with Bi4Si3O12. Under the excitation of 261nm and 393nm, there are some sharp emission peaks of Eu3+ ions centered...

Nowadays, the biggest problem that has influenced the using effect of wireless networks is that the transmission signals are easy to be affected by the external factors as well as the hardware equipments which are easy to be damaged, which lead to the phenomena like bad performance of transmission signals,...

For reducing the injuries of pedestrians when the collision accidents between pedestrian and vehicle occur, the design of car front structure has been proposed based on pedestrian protection, the design scheme includes a mechanical cushion structure of car bumper and a mechanical bounce device of hood...

The ideal design of the bumper should take full advantage of the bumper plastic deformation to absorb most crash energy in automobile collisions. In the paper, the bumpers with different inner structure (circular cross section form and honeycomb cross section), different materials (Al alloy, structural...

Arc ablation is directly related to the arc energy, which is proportional to the arc current and arc voltage. Existing fee control scheme of smart meter is that when power consumers delay the payment of electrical bills, the load switches trip; and when power consumers recharge successfully, the load...

Buton Rock Asphalt, as a natural asphalt modifier, can be easily dissolved in matrix bitumen, which improves high temperature performance water stability performance and anti-aging performance of asphalt mixture greatly, and lead to the simple production process and easy promotion. However dry mixing...

.In this article, we introduced the classification and prediction algorithm of data mining into aircraft engine fault diagnosis, then analysis and compare the Random Forest algorithm and Neural Network algorithm.The simulation of these algorithms and experimental results show that the two methods have...

The ownership structure is the basis of the development of companies, and performance measurement is critical for company to improve incomes. This study has empirically examined the relationship between the ownership structure and firm performance using a balanced panel of listed logistics companies...

O. Henry was a well-known American writer in the world literature history. His writing is vivid and he is good at using irony, paronomasia, metaphor, metonymy and exaggeration to make the story full of fun. He is a master of surprising endings, and he usually design story plots dramatically, and makes...

The comparison of the induction motor rotor common fault simulation, the fault characteristics are obtained this kind of failure of the motor through theoretical derivation and simulation model is established in the fault condition of the motor based on the multi loop theory, the running state of a motor...

Clean Development Mechanism (CDM) is one mechanism that can bring significant economic and social benefits, can solve climate and environmental problems by market means, and it is also a win-win mechanism for cooperation between developed and developing countries. This paper will classify the related...

This document investigated mining residents' response to the relationship between rare earth mining and environmental protection. Research shows that the vast majority of the interviewees consider that the rare earth mining will have a serious impact on the local ecological environment and the relationships...

According to the needs of the reader's personalized consultation, a self-help reference and consultation system is constructed based on micro-video courses and new media methods. The system consists of "micro-video Q & A classroom", resource navigation, Advisory website, QQ group and other real-time...

The construction of practical teaching system is a key way to improve students' ability. The theoretical study of the construction of the economics and management discipline and the process of practical teaching are stated views on the construction of practical teaching system, including objectives,...

Based on the organizational commitment theory and self-efficacy theory,this paper constructs a social Q&A community user model for knowledge sharing behavior from four dimensions: Affective commitment, continuance commitment, normative commitment and knowledge self-efficacy. Moreover, the model and hypotheses...

At present, our country economy enters the new normal, the strategy of the Belt And Road is not only beneficial to promote trade between the countries and regions along the interaction, more conducive to promoting the transformation of the pattern of economic development in our country. As the new starting...

As the connection of professional education and practical teaching, the cooperation between university and enterprise has become an indispensable beneficial complement of the professional education in universities. However, the cooperation degree and effect after the establishment of cooperation alliance...

This paper uses state space model to study the impact of electronic money on commercial bank loan business. Through the establishment of a theoretical model system, the research methods are selected, and the indicators are selected and processed. Finally, the impact of electronic money on the commercial...

Parking lot is one of the important public facilities for all people because of its function to accommodate the stopping vehicles. However, because of its limited parking area, a lot of vehicle users park their vehicles at side of the road. It resulted in street problems because the road become narrower...

In the teaching of college English, English translation teaching can not only reflect the translation level of college students, but also a reflection of college students' ability to learn English. Therefore, it is important to say that the status of college English translation teaching in college English...

With the number of college graduates increasing and the number of social employment posts not increasing, the pressure on the job market is increasing. The impact on the employment of college graduates is inevitable, and the contradiction between the employment and the market is gradually emerging. And...
