Athletes often occurrence sport injuries in volleyball training. The main cause of this event is due to the lack of awareness of athletes is not clear. There is some athletes in the injury situation is still not fully recovered with practice, it is very big harm to athletes. Therefore, in order to minimize...

With the further development of Chinese economic development and urbanization, in order to better solve the current problems of urban development in China, low-carbon city construction is a better development direction and ideas. Based on the fundamental needs of urban development, this paper analyzes...

This essay categorizes the empirical evidence by developed countries firstly and developing countries secondly. Within these two groups, this essay divides each group into two subgroups, by general and specific evidence. In addition, we allow the inclusion of evidence on seasonal price changes on developed...

As a core course for freshmen and sophomores of English major, Basic English teaching still exists lots of complexes such as the restrained teaching mode, little teaching duration, less interaction between teachers and students and unsatisfied teaching results. In this paper, the author has conducted...

Infotainment rose in the late 1980s and early 1990s and boomed at the end of the twentieth century via Internet and multimedia. Now, with the rapid economic development, the audience wants to get more amusement through news media after work, so plenty of infotainment sites and apps have sprung up, maximizing...

In This paper, the relevant research is carried out about seabed sound reflection . It has influences on the test results of the real-boat test based on the acoustic holographic technology. The effects of seabed reflection on underwater acoustic test is analyzed, through simulating sound field of free...

This paper introduces the design of a radar plane position indicator (PPI) fast debugging equipment based on USB. Hardware platform is a high-speed 16 channel date acquisition card -USB4716,which is based on USB. Its internal actual is 8 parallel 16AD module. The sampling length and sampling frequency...

Since the flash point of the electrolyte's organic solvent is very low, the use of improper dismantling way can easily cause the battery to ignite or even explode. Additionally, the residual voltage of the discard EV battery is very high, far exceeding human safety voltage. Improper dismantling way is...

Independent photovoltaic system needs energy storage in order to balance the power and improve its instability of power generation. A scientific control strategy can combine the PV cells to the battery system organically. The lithium-ion battery can be the bridge to achieve this target. This paper presents...

Serious pollution of waste gas, waste water and waste residue are generated by calcium carbide-based polyvinyl chloride (PVC) production in China, especially the mercury pollution on account of using a mass of mercury chloride catalyst (HgCl2). This study introduced main methods and techniques which...

The Mesoporous Ge@C sphere has been designed via a modified St”ber method and an in-situ solution deposition. Compared with the pure Ge nanoparticles, the as-synthesized Mesoporous Ge@C sphere nanocomposites show much better cycling stability and rate capability. That as-prepared anode material can maintain...

The massive data query methods in database is studied to improve accuracy of query. In the process of data querying in the database, once the data volume is overflow and thetype of data becomes complex, the query requires a lot of restrictions, resulting in time-consuming and low query accuracy rate...

Palmprint recognition is an emerging biometric technology that identifies a person based on the hand image. In this paper, a novel palmprint identification method based on Gabor wavelets and Local Direction Pattern (LDP) techniques has been proposed. The Gabor response images at different scales and...

As the device in general inspection maintenance, can only carry on the system static parameter measurement, and dynamic performance of the system only can be judged by qualitative observation. In this paper, we adopt modular design scheme and the method based on synchronous sampling and real-time data...

With the development of power electronic technology, harmonic load is one of the main reasons for damage to the power quality of the limited capacity power system. Firstly, the functional requirements of harmonic load model in the three-phase four-wire isolated power supply system are carried out according...

This paper deals with a DC-micro-grid with renewable energy and conventional energy. In the DC microgrid system, it is a key problem to keep balance between supply power and demand power. Based on the analysis of the operational priority of micro source and load, the priority model of micro source and...
