Abstract: Drawing Management System (DMS) has begun to be used more and more widely in modern enterprise and public institution. It has become one of the necessary tools to improve image file management efficiency. A subsystem model based on three layer of structure is put forward in this paper which meets Workflow Management Coalition (WfMC) standard. The model consists of workflow interaction, process management system, message mechanism, workflow engine. Each module finishes their own job to realize the auto run of DMS’s files.

Abstract: Tolerance allocation have significant influence on the manufacturing cost and quality loss cost. In order to obtain optimal tolerance, Lagrange multiplier method is used to minimize the summation of manufacturing cost and quality loss cost subject to constraints on product functional requirement. The reciprocal power cost-tolerance model with different functional constraints is considered, and closed-form optimal tolerances are obtained. Using the model proposed in this paper, the optimal tolerance can be obtained quickly and accurately. One example is used to illustrate the method proposed in this paper.

Abstract: Through the study of the seat size parameter change on the body pressure distribution effect, the powerful references to comfort design of office chair were explored. By using Canadian XSENSOR X3 PRO V6 test system, human body pressure distribution and subjective comfort evaluation in different back angle of 6 objects were tested. The data were processed by statistical analysis software SPSS 16. Then the change of maximum pressure, average pressure, contact area of seat surface and backrest, as well as the vertical pressure distribution curve with the back angle were obtained. Finally the comfort indicators of daily office chair were determined based on body pressure distribution, and the most comfortable back angle of office chair were also solved. Thereby it can provide reference for those who want to design comfortable daily office chair.

Abstract: At present, most of infant application products just rest on the level of beautiful interface while the usability of application interface is less noticed. The infant here and mentioned in the full text particularly refer to infant of 15-36 months old. From the point of view of visual perception characteristics, the paper mainly carries out an analysis of the usability design of application interface of infants. For the start, the paper briefly states the connection between the usability of infants’ application interface and the visual perception characteristics, then gives a detailed analysis of the influence of the visual perception characteristics in the usability design of infants’ interface, and preliminarily sums up the direction of infants’ application interface usability design.

Abstract: Start from the university student group that believes in Christianity, this paper conducts research on the needs of this special group in the field of mobile applications. Follow the user-centered design method, this paper investigates the special needs on the religious belief of this special group and using situation of mobile application software, explores user demands, applies the kano model to conduct attribute matching for the needs of users, and analyzes with weight so as to obtain priority ranking of the needs and provide design reference for the development of mobile application software for the Christ crowd.

Abstract: Through the CV(Control Vertices), NURBS curves, NURBS surface and the shell to research the principles of AliasStudio. And at the end of the article, describing the characteristics of advanced surface design of AliasStudio.

Abstract: Network virtual technology can provide solutions for experimental courses. It is low-cost, function congruent advantages, and the teaching cross-regional requirements. Virtual teaching platform can be real-time interaction between teachers and students. VRML-Java synchronized platform is designed in the paper, we initially realized the online substation system, and it includes the control and protection system, monitoring system, event log and fault recorder system, same period closing system. The virtual platform solves some challenges in the prototype experiment, increases knowledge and deep understanding to students, it gets better teaching results.

Abstract: PBL model is not only refers to problem-based learning but also refers to project-based learning. In this mode, teacher is an active guider and the students are self-learning teaching in groups around the problems. The specialized fundamental curriculum, Building Architecture, is practiced as an example. This article extracts three Projects and forty Problems. The theory teaching and course design are taken a comprehensive view of the situation as a whole. This curriculum reform practice has proved that PBL mode can raise students' the ability to analyze and solve problems, and it is an important way to carry out the Excellent Plan in the course teaching.

Abstract: Currently, engineering majors because of innovative talents of engineering and technology are needed. However their curriculum, management and evaluation criteria often refer to those of liberal arts and science majors which have been established for years. Meanwhile, there is no comprehensive understanding of engineering and its related ideas. It will disappoint the faculty and disqualify the students. In the article, we will describe in detail the special characteristic of engineering and claim that engineering concepts play an important role in promoting engineering teaching in universities.
