The management of college students as a way to promote the quality of teaching in colleges and universities to promote teaching reform has always been the focus of the work of colleges and universities in China.In the actual management of college students, student management has shown the survival of...

(17664, 16512) LDPC code is simulated under AWGN channel. The simulation is led on FPGA platform, with Layered Normalized BP-Based decoding algorithm. The shifting of measurement point is under consideration, where the soft information for decoding is inaccurate. LDPC performance under different situations...

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...

The emergence of the Internet led to a period, also brought a lot of convenience to people's life, and the wave of Internet online shopping has gradually become another mainstream network service. School students now do not have a very good handling for second-hand resources, which not only wastes the...

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...

In this paper, the microcontroller interrupt control technology, designed a simple microcontroller to control the LED lights off simulation system, the system was applied to the lectures can be intuitive so that students understand the process of computer disruptions, achieve a multiplier effect of teaching.

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...

This paper investigates if accounting evolved as a result of the interaction of special economic, cultural and political institutions which prevailed in Medieval Italy. A two-step approach is implemented by the Historical and Comparative Institutional Analysis. First we investigate the features of above...

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...

In the power operation, according to safety regulations, the staff must wear insulated gloves. However, in practice, the staff is easy to overlook, therefore, to improve security, we have developed a hand-held insulation tool detection alarm device. Method: Device using k60 microcontroller, microcontroller...

Either the alveolar bone defects or the severe absorbed alveolar bone led by the teeth extraction could have an effect on the orthodontic teeth movement. Guided bone generation technique has supplied a new method for the above clinical difficulty. Platelet-Rich Fibrin has been reported in the orthodontics...
