Abstract: Described a design method of universal test tooling of automotive body electronics unit.The test is divided into two parts of host computer and console computer,the host computer is application related, it is the combination of the test items, in the form of a package combinations on the PC,console computer has nothing to do with the application,it is the combination of the signal channel,achieve a variety of signals channel related to the nature of the body electronics unit in the form of real-time embedded system, As signal channels and interfaces,it establish hardware connection with the EUT(equipment under test), achieve the test interface configuration and monitoring.Through the different test software of the host computer and different connection of console computer with EUT, through clipping of specific testing software, achieved test during the development and production process, and also, testing different automotive electronics by selecting different test software.

Abstract: A kind of non-invasive impedance cerebral blood monitor is designed on the basis of virtual instrument technology. The system realized the real-time collection and disposal of two-channel cerebral blood signals. Admittance encephaloloop (AEL) was composed of admittance encephalogram (AEG) and admittance differential encephaloloop (ADEG), and the parameters which reflected cirrhosis of cerebral arteries included drag index, elastic index, pouring index, fast inflow phase index and so on, which were calculated by AEL. The instrument can detect dual cerebral blood wave of the patients with real-time and dynamic stabilization. Non-invasive impedance cerebral blood monitor can detect difference between cerebrovascular patients and normal persons. It provides a convenient method for researching, preventing and epidemiological studies of cerebrovascular diseases in our country.

Abstract: With the development of wind turbines trend of single machine but large capacity, and with the concrete wind-turbine tower has many advantages such as corrosion resistance, high stability, convenient manufacture in-site and lower maintenance cost, concrete tower will have more and more wide prospect. Application of large finite element software FINAL, the main research is the influence of SSI effect on wind power tower natural vibration frequency. We can know that SSI effect is very important for wind power tower natural vibration frequency. So we can not ignore the influence of the interaction between soil and structure. We should pay more attention to this actor when we design or analyse a wind power tower.

Abstract: In recent years, the rapid development of industrial computer technology has provided the foundation for manufacturing automation and informatization. Intelligent Flexible Manufacturing Cell is being integrated with more complicated additional functions to realize the cooperation among CNC machines or between CNC machine and robot. How to detect the systems status rapidly and timely becomes one of the most concerned problems. This paper proposes a remote monitoring system for Intelligent Flexible Manufacturing Cell, designs the remote monitoring platform, determines the communication systems network structure, and establishes the database and software of monitoring system. The result shows that the system obtains a good result in practical application.

Abstract: The monitoring of the settlement of the shield tunnel plays a very important role in the traffic safety of metro trains. The monitor precision and the timely are required for the settlement of the shield tunnel. The automated monitoring must be introduced to the monitoring work, and becomes powerful monitoring method. The article introduced the measurement principle of the hydrostatic leveling system (HLS), through the hydrostatic leveling system preliminary utilized in metro monitoring for construction deep excavation above shield tunnel. The monitoring data and the construction safety are analyzed. Regularities of settlement of the shield tunnel are summarized. Suggestion is made on the monitoring range.

Abstract: This paper presents an improved entropy method to assess the post-fault power system. The proposed method defines four indicators to assess the seriousness of the post-fault power system according to the specified severity function from the aspects of static stability and transient stability, and to weight the severity indicators through an improved entropy method. The risk assessment function for system failure is then established by combining the severity function with line fault probability model from statistical analysis of historical in power system. This proposed method has been tested with IEEE - 9 nodes system. Simulation results show that the proposed improved entropy method is able to make full use of various information, effectively avoids the problem of over weighting of any indicators, and improves the reliability and accuracy of the failure risk assessment of the power system.

Abstract: The ultra-wideband through-wall detection radar (UWB-TWDR) system is burgeoning and considered as one of the promising systems for rescue and military use. In this paper, the mechanism and structure of a simple and low-cost UWB-TWDR system are presented. Compared with previous systems, android based mobile devices were used to replace the traditional PC, making the system more portable and affordable for most users. In addition, correlation detectors were applied to simplify the circuit and further reduce the cost. The algorithm for locating and tracking during the process of acquiring and handling data from antennas was also discussed. Experimental results of our system showed a good performance in practical through-wall human detection.

Abstract: In this paper, microwave scan inspection was employed to detect the lack of fusion defect existing in the thermal fusion welds of high-density polyethylene (HDPE) piping. The thermal fusion welds without defects were firstly inspected by microwave scan technique. The obtained microwave interference pattern and the scan image produced were taken as the evaluation standard. Then the thermal fusion welds containing lack of fusion defects obtained under different welding conditions were inspected, and the corresponding scan images were recorded. The problems occurring in the welding processes that lead to lack of fusion defects in thermal fusion welds can be distinguished by analyzing the scan images. Mechanical tests were performed to confirm the effectiveness and reliability of the microwave scan method in detecting the lack of fusion defects in thermal fusion welds of HDPE piping.
