Abstract: Rapid Prototyping (RP) presents the automatic production of physical parts using by additive manufacturing technology. The start techniques for Rapid Prototyping became available in the late 1980s and were used to produce models and prototype parts. Today they are used for a much wider range of applications and are even used to manufacture production-quality parts in relatively small numbers. Rapid Prototyping is widely used in the automotive, aerospace, medical, and consumer products industries. In paper is presented process of design product development, product production and testing of products produced by Fused Deposition Modelling rapid prototyping technology.

Abstract: Researching on fatigue and comfortableness of human body, one of the most important items in people-first design, this paper introduced the importance of the analysis on fatigue and comfortableness, analyzed the current methods for evaluating the fatigue and comfortableness, stated the way to analyze a kind of product using ergonomic software. Finally, an example about the truck design was given to show how the analysis was carried out.

Abstract: JPEG 2000 is a new image coding system that uses state-of-the-art compression techniques based on wavelet technology. As interactive multimedia technologies evolve, the requirements for the file format used to store the image data continue to evolve. The size and bit depth collected for an image to increase the resolution and extend the dynamic range and color gamut. Discrete Wavelet transform based embedded image coding method is the basis of JPEG2000. Image compression algorithm for the proper use and display of the image is a requirement for digital photography.

Abstract: The thesis first analyzes the concept of mobile payment, and then it makes a distinction between remote payment and near field payment. In addition to that, it infers the development of global mobile payment, which involves the users and the market size. Secondly it probes into Chinas rapid development of mobile internet economy, whose 3G network and smart phones provides high-speed mobile Internet and visual, convenient interface for mobile payment. Thirdly, harmonization of standards of mobile payment will help create industry chain parties openness, cooperation and win-win situation and promote mobile payment intensive and large-scale development process. In the end, it probes into the win-win business model for the telecom operators and financial institutions: Telecom operators will lease SIM card space to obtain revenue and financial institutions will get more fee income.

Abstract: The virtual reality technology can help us to make more scientific and rational design, process more simple and optimized, and teaching more vivid and natural. This text, taking the human-computer interactive simulation of the upper limb operations for example, classifies a wide range of man-machine interfaces that related to the upper limb operations of human, and through the operations analysis and motion analysis of human to find a breakthrough point, so as to carry out the research of targeted countermeasures. The purpose of the research is to complete product platform to provide effective services for teaching and industry.

Abstract: The hardware structure of college students physical activity energy monitor has been designed through electronic circuit method in the previous research. Software Design of college students physical activity energy monitor by using LabVIEW is also proposed. User login module, physiological condition module, movement condition module, diet tracking module, virtual coaches module and other modules are also realized in the paper.

Abstract: A guide post is used to separate pavement from roadway and widely used for car parks, pedestrian safe zones and refuge islands as well as for asset protection such as columns, pipes from impacts [. But it is very easily hit hard by cars. This study uses the contradiction matrix in the TRIZ method, 39 engineering parameters, and 40 inventive and innovative principles to identify the areas of improvement to address the above problems. When the guide post is hit by a vehicle, a flexible structure located between base and cylinder can curve and spring back to original position, and therefore endures more powerful hit. In addition, the spring back function lets the guide post automatically return to original position to alert drivers. This structure will has more durable service life, so, it can be used to reduce the maintenance times, and cost for the users.

Abstract: It is important and necessary for the colleges and universities to cultivate the consciousness of science and technology innovation and improve the creativities of undergraduates according to the training objectives of the innovative ability of outstanding innovative talents. The construction of the college students science and technology innovation base was introduced mainly, including science and technology innovation base management and operation mechanism, the content and incentive system. The organic combination of the teaching in class and extracurricular was realized in the college students science and technology innovation base. The innovation base played an important role in cultivating and improving college students' science and technology innovation practice ability. The young college teachers produced irreplaceable function in the cultivation of creative personnel. With the operation mode that the science and technology innovation practice ability of college students was improved obviously, the good atmosphere of scientific research and teaching was formed, the student cultivation quality was improved obviously, the study ethos was improved obviously.

Abstract: Chinese women javelin thrower Lv Huihui won the championship of China Long Throw Open in 2013. However, there was still a large gap between her result and the world record. In order to improve her stroking techniques and enrich technological theories, we used advanced three-dimension picture to take up Lv Huihuis spell throw in game site. We also made three-dimension analysis on the last exertion skill and got the kinematics parameter to compare with the foreign elite women javelin thrower. The results show that Lv Huihuis stretch angel is 13.8° smaller than world elite athletes. Her flexibility is not so good that she cant do the full bow action completely. As for the last left knee stretching process, Lv Huihui and other Chinese elite athletes get the results of 5.3°and 10.2 °, while world elite athletes get 16°. It shows that Chinese athletes left knee stretching is not good. Lv Huihuis release speed is 23.36m/s, better than the Chinese athletes average level 21.36m/s, but this speed is much slower than the world elite athletes release speed 24.80m/s. It is the major reason that makes Lv Huihui remain a large gap with the world elite athletes.

Abstract: The basket with 1/2 turn to handstand on parallel bars is a representative movement of E group, which not only has some difficulty, but higher connection value. Modern three-dimension picture analysis will become the main method on technique diagnosis of kinematics parameter at game site. We took up Haibin Tengs (referred to as Teng, the champion of 2004 Athens Olympics) basket with 1/2 turn to handstand in Olympic trials for the national gymnastics championship tournament in 2012 and also made three-dimension analysis on it. The results show that during the downswing stage, in the case of maximum torque, Teng can control each link in the best position; during the upswing stage, in the case of overcome gravity, he can reduce the wastage of the kinetic energy as much as possible to allow him to maximize his speed; during the instant of release, the horizontal distance of the center off the bar is 0.83m, and the horizontal angle is 13.5 °. It is reasonable to twist when the body in such a position and angle. He contractions his shoulder, flexors hip to reduce the moment of inertia, increased rotational angular velocity so as to complete the action in a high quality. This is the main reason that he obtained the excellent result.
