The previous experiments have shown that hydrophobic properties of 20 kinds of human’s amino acid are different. It was of great significance to study whether hydrophobicity of proteins had a role in the research of the intimate relationship of proteins. Besides, it is also very important to balance...

Equipment procurement had the characteristics of long life cycle, high cost and high technical requirements and the budget may change. So the problem of how to select equipment vendors under the condition comes on. To improve the efficiency and reducing risk, a model of equipment vendor selections under...

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...

This paper changed temperature conditions to simulate by finite element software. We can observe the simulation results of the BLDC (brushless director current motor) stator resistance. Then we applied formula to calculate the BLDC stator resistance. At last, measuring the stator resistance of different...

In this work, the ground-based GPS data in the West of Taiwan Strait was used to remote sense atmospheric Precipitation Water Vapor (PWV) in Fujian, and dynamically analyzed the spatial pattern change characteristics of PWV, combined with meteorological data, in order to quantitatively analysis the relationship...

The present study reports that a modified coaxial electrospinning process, which was successfully carried out to control the diameters of shellac fibers. With a Triton-X100 in ethanol as sheath working solution and shellac ethanol solution as a core electrospinnable fluid, the coaxial electrospinning...

The measurement accuracy of the articulated coordinate measuring machine (AACMM) is different in different sub measurement regions. In order to improve accuracy, The method for dividing and merging of sub measurement region based on Density-Based Spatial Clustering of Applications with Noise (DBSCAN)...

It is highly important to choose suitable of the foundation in underground engineering. With the engineering, the foundation is made of gravelly soil, which distributed discontinuity and had bad uniformity. Drilling method, dynamic sounding method and deep plate loading test were applied, combined with...

With the rapid development of medical and health undertakings in China, the requirement of the qualified medical service system was increasing, more and more medical had introduced the advanced medical equipment, the introduction of a large number of equipment to make the medical equipment maintenance...

The diagnosis of breast disease in Europe and other advanced western developed countries were mainly the biopsy technique, which included fine-needle aspiration biopsy for cytological diagnosis and core needle biopsy for histological diagnosis. This two methods could figure out the basic pathological...

This article made Computer Simulation Technique to analysis the relationship of the different heights of hit tennis and serve’s effect in the course of tennis serve. The results show that with the increase height of hit tennis the effective area of tennis serve also increased significantly; the success...

This paper has investigated the effect of hue on visual comfort and depth perception through subjective assessment experiments with the stereoscopic images generated by computer. The evaluation results indicated that the variable of hue would significantly affect the viewing experience under different...

The consumption of electric power is increasing with the continuous development of China's economy. The temperature rising limits testing is the important performance for low-voltage metering cabinets and circuit breakers. The strategy for temperature rising testing usually had many questions such as...

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...

Precision of ball screw had a great impact on the positioning accuracy of NC positioning platform. The lead error and backlash of ball screw, which could be accurately measured by laser interferometer, were two key factors affecting the positioning accuracy of NC positioning platform. By setting the...

Based on information sharing idea, BIM (Building Information Modeling) technology had been widely used in construction industry. Employment Guarantee for Migrant Workers is hot topic in Chinese construction industry. There were few articles focus on using BIM to solve the Employment Guarantee problem....

Using the methods of text analysis, interview and logic analysis, it made a reflection on the club teaching model of public physical education in Yan'an University. The results show that adopting club teaching model in public physical education was in line with the trend of teaching reform and development,...

In this paper, a dark background image-denosing method based on KPCA is discussed. First of all, the analysis of KPCA features is used to extract features from the training samples, and then discards the features which had small variance to form the feature space. Second, for reducing the noise, the...

In this study, 64 cases of forced isolation drug addicts conducted a general survey, a number of Minnesota Personality Test (MMPI). The results showed that male drug addicts in Southern shandong region generally had low cultural level;Family economic situation was in general;Divorce rate was higher;...

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...

Since 2002, the number of registered trademark applications in China has consistently ranked first in the world. However, some scholars questioned whether massively registered trademarks had significant positive influences on enterprise competitiveness. From the perspective of trademark layout of enterprise...

Alternative conception is students' conception of scientific concepts that are inconsistent with the conception of scientists. Various studies show that alternative conceptions of chemical concepts occur in students, including acid-base concepts. Various identification of alternative conception methods...
