Abstract: The magnetization switching process of a perpendicular exchange spring system was investigated using micromagnetic simulations. An exchange spring hysteresis loop was observed in this work. Details like coercive field and remanent magnetization are discussed .

Abstract: Standard skyhook control algorithm is inefficient in controlling of the parameter-varying magneto-rheological semi-active suspension system. Based on model reference adaptive control theory, a minimal control synthesis-skyhook (MCS-SH) mixed control algorithm was designed. Ideal skyhook control was taken as the reference model; the feedback control law of MCS algorithm was improved based on the feature of magneto-rheological damper (MRD). The results illustrate that the sprung mass acceleration and suspension deflection are decreased through MCS-SH algorithm, the ride comfort of vehicles can be improved significantly, and the MCS-SH algorithm can adapt to the variation of suspension parameters.

Abstract: Aiming at signal detection of radar target, concerning about on the basis of the influence of SNR on detection probability when false alarm probability is given based on N-P criterion, a kind of multi-sensor fusion detection based on SNR is put forward. It can improve system’s detection probability under the condition of required false alarm probability in the detection of low SNR signal. The simulation results show that the detection performance is significantly increased, no matter fusion detection system is composed of same sensors working in the same working point or different sensors.

Abstract: Through theoretical analysis of the working condition of the tension roller and stress, user can discuss the main reasons of tension roller slip, and put forward the preventive measures to eliminate tension roller slip by using Euler formula and the research on the tension roller slip phenomenon of cold rolling. This technology has significant practical meaning for improving both the quality and efficiency of product.

Abstract: In this paper, a predictive model has been established for the combat effectiveness of amphibious assault vehicles by the method of supporting-vector regression. It has a good fitting result after trained with the samples. Then this model is used to predict the combat effectiveness of the sample under evaluation. The SVR approach can convert the practical questions into the high-dimensional feature space through non-linear transfer, and construct the linear decision functions in the space to realize the original non-linear decision functions. This approach has its significance for the prediction of combat effectiveness of AAVs.

Abstract: The main principle of radar non - contact life detection technology is the use of electromagnetic wave by the human body, the echo signal is modulated by the surface movement caused the life activities of the human body, so that some parameters of the return signal change. The research on the non contact detection technology, completed the construction of life monitoring system module of hardware, design of software algorithm, real-time data acquisition, and the use of special software algorithms, to detect these changes, and then extracting parameters of human life.

Abstract: Bolt as a connecting device plays more and more important role in various types of industry equipment. According to the needs of the domestic industry and on the basis of the automatic screw tightening control system requirements, this paper describes the design of screw-Machine electrical control system based on IPC independently.The main work probes into the electrical control system’s hardware structure and software structure.

Abstract: To address the problem of low efficiency of manual testing of CTCS-2 train control center, an automated testing of train control center script technology was proposed in this paper. This method makes full use of the characteristics of Lua programming language which is simple and efficient and can be embedded in C or C++, The control scripts based on Lua language are used to control the automatic test behavior and the data scripts are used to store data of testing case. By this way, the testing logic separates with the testing data and independent of the automated testing engine, by which greatly improve the scalability and flexibility of the testing platform. Through the use of automated testing of train control center of HengYang-LiuZhou passenger dedicated railway, it proves that this technology can be a good service to automated testing of train control center.

Abstract: According to characteristics of monitoring system, firstly, making some preliminary processing for history database through the Apriori algorithm of association rules. So that digging out some useful data for the system, and concluding the initial sample data. Secondly, analyzing, training and processing the data using artificial neural network to make the monitoring system control strategy intelligent. On the other hand, the model can be used to forecast some useful data for monitoring system, to make management of tunnel more efficient.
