Nowadays, it has became a widespread approach for achieving rich information in modern web applications using AJAX ,which cause two serious problems for web crawler. One is the incomplete information getting from web page due to the inability to parse dynamic web page. Another is the efficiency of the...

The polymerization of acrylamide was initiated by complex redox system in aqueous solution.Meanwhile, according to the best experimental craft,we conducted a pilot-scale polymerization of acrylamide.We studied the effects of different pilot experiment intrinsic viscosity of the polymer, dissolution time,...

The ternary cation flocculant P(AM-DMDAAC-DMC) was synthesized by aqueous solution polymerization with raw materials of acrylamide(AM),and dimethyl diallyl ammonium chloride(DMDAAC) and methacryloyloxyethyltrimethyl ammonium chloride(DMC) with the complex redox as initiator.Effects of cationic mononer...

The advantage of nonlinear ultrasonic method in micro defect detection has been widely recognized. It has higher sensitivity than linear ultrasonic. Vibro-ultrasonic modulation(VUM) method was adopted in the paper, and fiber Bragg grating(FBG) was used to sense nonlinear signal instead of piezoelectric...

We proposed a method to resolve the problem of optical system defocus phenomenon by using the chromatic aberration of the single lens optical imaging system through reverse thinking. Furthermore, we designed and built the production which use SDRAM to collect data for CMOS image information literacy...

It is found that some operating faults of the intelligent electric meters are caused by the performance of the built-in load switches. In order to determine the characteristics of the built-in load switches, the performance of the switches are tested and analyzed. The factors, including the complicate...

No-reference image quality assessment is the future research direction in the field of image evaluation. A new no-reference image quality assessment based on the generalized evidence theory was proposed in this paper in order to deal with the measuring problem of the large scale samples under the optical...

School-enterprise cooperation is the basis of the reform and development of animation major in high vocational colleges, and production and education integration is an important guarantee to improve the quality of education.Animation major in high vocational colleges should hold the great standard of...

With the development of Internet and cultural industry, Guangzhou formed three modes of the integrative development. According to the modes, the paper puts forward three paths of the integrative development of Guangzhou Internet and cultural industry, and three countermeasures combining with the paths,...

In this paper, we use the idea and method of evolutionary game to construct the asymmetric game problem information sharing in Stackelberg model, which is dominated by the manufacturer.The results show that the dynamic evolution of the system is not stable. The success or failure of information sharing...

For the strong theoretical, practical and applied characteristics of "Hydraulic and Pneumatic Transmission", the traditional teaching methods of the course has been facing difficulties which the teachers find it difficult to teach and the students feel it hard to learn for a long time. In order to improve...

In order to meet the requirements of engineering education accreditation, aiming at the important basic course of Control Engineering Fundamental, a teaching model is put forward , which combine with the case teaching ,multimedia, MATLAB professional software. It enables students to have a deep understanding...

China Camellia fruit shell to mechanical machine has not been popular, especially in rural areas, this paper designs a kind of advanced and applicable Camellia fruit shell device, used to make more efficient fruit tea, Camellia fruit hulling machine, which comprises a shell, a cutting mechanism, tie...

Indoor positioning is becoming a very popular research direction in recent years. In this paper, we realize real-time trajectory calculation through the fusion of inertial and vision. We have two experiments in different environments and we find that the algorithm's error is below 50% of pure inertial...
