Abstract: The internet of things on policy highlands is faced with pressure of talent shortage, but the majority of colleges and universities are facing that professional setting is not prominent characteristic. In addition, the Internet of things technology application in the coal industry is different with in business networking. The specialties reform of "Network engineering" is proposed in this paper, and is accordingly pilot. Experiment results show that, combining the school advantage discipline, the specialties reform based on original "Network engineering" is successful. It can effectively meet the professionals needs Internet of things in the coal industry. At the same time, it improves learning interests and employment prospects of student.

Abstract: This paper does some research of mining for unexpected event from customer feedback comment, and it helps to forecast and alert the service problems. With the new services in Telecommunication businesses, lots of atypical unexpected incident hides in Telecommunication Feedback text. The incident has small probability and atypical attributes, and hard to understand and unobvious by ordinary way. We define this atypical unexpected incident as unexpected event. We construct the mathematical model for unexpected event, design the extracting algorithm, and try to verify its efficiency with Feedback text. The experimental results map out the correct possibilities for our algorithm.

Abstract: General prey pursuit problem used capture strategy between agents in limited grid space. In prey pursuit problem, there are a lot of problems such as occurrence of collision between agents, imperfection capture that can be produced from corner of restricted grid space. But, this causes actuality deficiency problem of experiment environment itself. In this paper, we propose an experiment environment that considers actuality and new capture strategy that using direction vector to solve prey pursuit problem that is typical experiment model of multi agent system. Therefore, we proposed continuous experiment space of grid space of circular type that is environment similar to the actuality world in this paper, and agents in proposed experiment space solved prey pursuit problem through direction vector that uses distance information and direction information between each others. The proposed method could capture prey effectively through using direction vector in new environment, and we solved imperfection capture and agent collision problem that happens in general research.

Abstract: The paper introduces the data treatment methods of the wireless signal in a car tracing system at automotive manufactures stock yard. The paper shows the overall of the function of the wireless tracing system and introduces the Fingerprint method used in the system first. And then, the paper introduced how to use the wireless signal data to build up the database used for Fingerprint method in each board router. Two different types of data have been mentioned in the paper which are going to be stored into the database are average data and Fuzzy data. The following paragraphs of the paper introduces the application of the wireless tracing system based on Fingerprint method and discusses the influence of the different grid definitions of the stock yard to the application.

Abstract: ntelligent systems are becoming main parts in more and more building engineering with the development of economy in China. It is given in this paper that the focal points in supervising intelligent systems of building engineering. Quality control procedures are described in detail, which can ensure that the intelligent system can realize the design requirements and meet the industry standards in the construction, system commissioning and testing. The summary of supervision in this paper comes from a large number of famous building engineering in Beijing, such as the National Stadium, ZhongGuancun Science and Technology Square, Beijing Hospital, Peking Union Medical College Hospital, etc.

Abstract: A rapid and sensitive cataluminescence-based gas sensor utilizing nanosized Y₂MnO₅ as the sensing materials for determining dimethyl ether in air was proposed. The luminescence characteristics and the optimal conditions were investigated in detail. The gas sensor showed high selectivity for dimethyl ether at 620 nm and satisfying activity at 210°C under the optimized conditions. The linear range of cataluminescence intensity versus concentration of dimethyl ether was 5~120 mg/m³, and the detection limit (3σ) was 3 mg/m³. No or weak interference was observed while the foreign substances, such as formaldehyde, ammonia, ethanol, benzene, carbon monoxide and sulfur dioxide, were passing through the sensor under selected conditions. The gas sensor displayed good stability for continuously introducing dimethyl ether over 100 h, and allowed real-time monitoring of dimethyl ether in air.

Abstract: The interior thermal power consumption of fiber-optic gyro is calculated, According to the interior heat source distributing of fiber-optic gyro, the heat design project of fiber-optic gyro is given and designed two kinds different fiber coil framework. The two kind different fiber coils are simulated on heat exchange by ANSYS software. Contrast on the temperature characteristic of two kind different fiber coil gyro has been done by experiment. The simulation and experiment results show that the temperature characteristic is improved to this fiber-optic gyro with interlayer fiber coil framework, the bias stability of the fiber-optic gyro is improved with temperature variety, and the interlayer fiber coil design project is effective and validated.

Abstract: A design of the fuzzy self-tuning immune PID controller is proposed. The controller, which combines immune feedback mechanism and fuzzy PID control, executes the self-tuning of PID parameters in the control system. A simulation experiment is presented in light of a tactical missile autopilot transfer function. Simulation result shows that the performance of fuzzy self-tuning immune PID controller is better than that of fuzzy PID controller, especially in its robust performance for variable parameter system.

Abstract: Line heating is an important technique for processing hyperboloidal outside plate of ship hull. To realize the automation of the line heating, the deformation rule in line heating should be researched. In this paper, the computer vision measurement technique is applied to find out the disciplinarian of linear deformation in line heating. The principle of computer vision measurement is firstly introduced in this paper. The emphases are the images collection, camera calibration, edge detection, and 3D data reconstruction. Then some key techniques for ensuring the measurement precision are presented. At last, the result of experiments is given. The experiments showed that the measurement system was valid for measuring the linear deformation of line heating.

Abstract: This paper came up with introducing four dimensions: learning mood, cognitive state, learning style and interest preference and so on for the semantic web, based on the analysis the present situation student models at home and abroad. Realized to classify learners and establish student models which used an improved similarity algorithm, and the student model applied to adaptive learning system, which not only could solve the lack semantic in adaptive learning system, and greatly improves the practicability, intelligent and personalized.
