A tourism team is usually built up by tourists from different areas with different backgrounds and lifestyles, so that how to manage a tourism team has become a hot topic of current research. In order to solute this problem, we have designed a management system based on radio frequency identification technology which composes by tag reader and tans. The tag reader is carried by guider and the tags are carried by tourists, so guider can monitor every tourist who carried tag. Each tag has its own special identification number, and each number corresponds to one person. Guides can call every one who carries the tag at any time, so this system could solute the management problem to some extent.

Torque ripple seriously affects the performance of brushless DC machine (BLDCM). Analyzed the principle of current hysteresis controller reducing non-commutation phase current which made BLDCM system become more hysteretic, the precise model of BLDCM is difficult to obtain. The fuzzy-PID control based on current hysteresis controller was proposed to diminish torque ripple and overcome the shortcomings of BLDCM system. The model of BLDCM control system with fuzzy-PID control was established and simulated. Compared with current hysteresis controller results, the torque ripple reduced from 160% to 35%. The comparison of experimental results verify the effectiveness of the fuzzy-PID controller which can reduce the amplitude of torque ripple.

The underwater plasma sound source, as a significant application of pulsed discharge in water, has been employed for underwater acoustics. During the underwater high-voltage discharge, there will be an intense electromagnetic radiation (EMR). Therefore, it is necessary to decrease the level of EMR. So firstly, the mechanism of the EMR during the underwater high-voltage discharge has been studied deeply. Secondly, in terms of the national standards and electromagnetic interference (EMI) theory, the parameters of antenna were confirmed. Thirdly, by using the antenna and some accessories, the EMR of the system has been measured and its characteristics of the time domain and the frequency domain were analyzed. The results show that EMI is serious. Lastly, in order to reduce the level of EMR, the electromagnetic compatibility (EMC) design was used and some experiments using the modified system have been done. Under some special situations, the level of the EMR was reduced over 6 dB.

The supervisory information in pipeline such as the temperature and the pressure difference should be transferred by the smart plug, meanwhile the actions such as the plugging, plugging releasing, and safe preparedness starting should be realized according to the outside control instructions. Therefore the special low-frequency modem should be designed to solve the communication problems. According to the working principle of the low-frequency communication system and the low-frequency induction communication theory, the low frequency communication system which suitable for the working environment of the smart plug is designed, and the communication protocol is determined; the stable communication carrier of 20Hz is produced by the AVR MCU, and the method for Manchester coding and decoding based on the AVR MCU is put forward. The low-frequency communication system has good applicability which can be verified by the experiment.

Chaotic maps can be used in constructing hash function because of their properties, such as parameter-sensitivity and random-similarity. Many algorithms have been proposed for chaos-based one-way hash function. However, how to map bit strings into decimal number is ignored by these algorithms. The Analysis for a chaos-based one-way hash algorithm shows that it is a very important problem. Probably, selecting an inappropriate map will result in the collision of hash values. A non-linear map method is presented. The computing result shows that it is valid.

In recent years, MIMO MC-CDMA system was extensively studied, its uplink synchronization model using space-time block coding (STBC) is described in time-varying multi-path fading environment, a new multi-user detection algorithm based on MBER (minimum bit error rate) was proposed for it. The algorithm can be realized using kernel density estimation and gradient descent methods. Simulation results show that, comparing with the traditional MMSE-based detection algorithm, the new algorithm has better bit error performance in case of not increasing the computational complexity.
