Abstract: This study breaks through traditional displacement and inclination monitoring methods in excavation engineering, and proposes for the first time that combining excavation engineering with subjects such as Iconology, Signal Processing and Wireless Sensor Network, use Digital Signal Processing, Digital Image Processing, and Micro-Displacement Sensing technology for monitoring and processing various types of displacement. Then collect all monitoring points’ information through Internet of Things technology into database processing platform for processing, in order to achieve automatic real-time monitoring.

Abstract: The calibration of structured light vision sensor is the key technique in structured light 3D vision measurement. In this paper, a novel method for structured light vision sensor calibration is presented. In our method, a simple 2D planar target is used, and the corresponding world coordinate system is set for the target at different positions as well as the transformation relationships between world coordinate system camera coordinate system and image coordinate system. The intersecting line equations at different positions are unified under the camera coordinate system after processing. Then we can use least square method to fit the structured light equation. The experimental results show that the proposed method is an efficient method with high precision and simple procedure.

Abstract: With the analysis of the cause and solutions of hydraulic maladjustment in the variable flow rate HVAC systems, two control mode of the terminal constant pressure difference system and the electric adjustable dynamic balancing valve system are studied, include the comparison of their energy consumption under variable flow rate condition , and the research of their flow characteristic curve in variable flow rate control systems.

Abstract: This paper presents detailed technique and steps of data mining in sluice safety monitoring according to the monitoring data’s features. The tasks and objectives of data mining are defined and converted into the knowledge which can be realized by certain algorithm. The methods of data preprocessing is also discussed to eliminate or reduce redundant, noise, incomplete and inconsistent data. The examples of data preprocessing and data mining show how to apply the data mining technology in the sluice safety monitoring filed, which results indicate that the method presented in this paper is effective and can be used in other projects.

Abstract: Coalition formation of the Multi-Agent System is a key issue, mainly focuses on how Multi-Agent System dynamically generate optimal task-oriented Agent Coalition. This article will discusses the formation of Agent coalition applying genetic algorithm to the formation of Agent coalition, Experimental results show that the genetic algorithm can quickly and efficiently identify Agent coalition. Furthermore the performance and convergence rate are better than correlation algorithm.

Abstract: Interlanguage is an important issue in the field of second language acquisition for the past forty years. This study classifies the errors into three levels-lexicon, syntax and discourse, and then analyses the error examples to reflect the cause of interlanguage. The result may make some suggestions to the English teachers in English teaching.

Abstract: The paper analyzes the development status of colleges, the actual problems the graduates meet in the course employment, and the design goals and principles of employee management system. SOA employee management system was designed which based on the above conditions. The system maximizes the information shared with other systems through the implementation of the SOA system. And the system manages the information of graduates efficiently through the internet information platform of local management information system.

Abstract: The paper shows the status of college physical education personnel training in the view of the training objectives, curriculum, faculty and staff, and points out the problems of personnel training. It puts forward market-oriented humanistic quality as a college physical education personnel training.

Abstract: The management successful depends on the efficient decision. Moreover, the decision correctness is decided by the information quality in a large extend. This emerging subject of management information system is mainly researching in how to apply the modern computer and network technology to the efficient business management or even promote the management in the maximum limit. Management information system is the important symbol to achieve modernization for the corporate information management. The application of ERP (Enterprise Resource Planning), CRM (Customer Relationship Management) and electronic commerce is the significant method for the corporate information management. This article research the relation of management information system and corporate development.

Abstract: The college education has developed unceasing and the number of collegian is step up with more extrude contradiction of student employment. The tough job market requires the vocational counsel and management should be more scientific, standard and effective. At present, the applied employment management system for the graduates has the characteristics of high-efficiency, convenient with speediness that played an important role in high-efficiency employment of graduates. However, there has hidden danger of high-efficiency network security. The employment management and amount of relevant personal information might affect seriously for the network security questions. Therefore, research the network security of information management system about college employment is very important.
