Abstract: Home electronics is short-cycle product with time-sensitive, the market demand volatility and large features and the unreliable environment of supply caused by a variety of uncertain factors. The value of the home electronics will become very low or even lost if it is over more than life cycle. The unreliability home electronics quality of supply is analyzed using quantitative analysis method, the impact of the maximum expected profit and the optimal order quantity of the home electronics retailer by defect rates and customers claim were also discussed in this paper.

Abstract: The ecological theory is introduced into the construction of hospital information systems, focusing on the analysis of various factors in growth of hospital information system, on the basis of ecological theory ideas, the hospital information system studied as a living body, and the growth process is divided into budding of hospital information system construction, building the living environment of hospital information system, the growth stage of hospital information systems and development stage of hospital information system, the ecological chain of hospital information formed under the internal and external forces in the hospital, in order to build a complete growth model of hospital information system.

Abstract: Higher education institution is chose as studying object to examine the incentive issue of teachers, which is of great theoretical and practical significance for the development of managing model for human resource for inspiring the latent of teacher. The asymmetric evolutionary game between higher education institution and teacher is studied based on imperfect information and the dynamic evolutionary equilibrium is also derived. Some cases are discussed in this paper and cooperation will be optimal selection if both sides will re-adjustment the distribution of benefits and this process of cooperation is an evolutionary process.

Abstract: Mining spatial information sharing platform, as a new type of mining information management systems, will greatly enhance the level of the existing mine information management and their ability to support production operations. Based on the analysis of the current information sharing framework, a new mining information sharing platform which is service-oriented GIS is introduced. Then, this article describes three key techniques to achieve: the SOA-based GIS technology, metadata technology and spatial database technology. Finally, the paper talks about the research way for the development of mining area spatial information sharing architecture in the future.

Abstract: Based on the design theory of non-circular gears, using Pro/E drawing module, a system of elliptical gears parametric module and simulation was developed. Machining non-circular gear by wire cutting can be achieved by using Pro / E manufacturing module, and then gear machining tool path is created, tool and process parameters is set and simulation of process tool and process of post-processing analysis was described. Through the above process ultimately to generate post-processing procedures which NC machine tool need and achieve the automatic programming of non-circular gear. Form the application example, it has been observed that the gear created by Pro/E simulated NC programs can correct mesh according to the theory transmission ratio and the effectiveness of the proposed approach.

Abstract: User-centered design plays a significant part in product design. GOMS user behavior model analyze the interface from the aspects of both users and objects, which helps the designers to create a user-friendly interface in an efficient way. In this paper, GOMS model was used to predict the efficiency of the two versions of input interface on a touch-screen mobile phone. In addition, the experiment was conducted to collect the data under the real scenarios, and paired-sample T test was employed to analyze the data. The results indicate the GOMS prediction model can be used to evaluate the efficiency of the mobile phone interface.

Abstract: This paper describes a hybrid process of Micro EDM and ECM to fabricate 3D microstructures. Micro electro discharge servo scanning machining (Micro EDSSM) is used to remove most part of workpiece material with fast machining speed, while Micro electrochemical scanning machining (Micro ECSM) with side-insulated tool electrode is used to remove the residual material and form the final 3D-structure surface. The application of side-insulated electrode during Micro ECSM is a key technological method to improve the machining accuracy of hybrid process. The effect of side-insulation film property to the movement of hydrogen bubble generated during Micro ECSM is discussed. The hydrophobic film can reduce damages to the junction between film edge and tool-electrode through the attraction to hydrogen, and a hydrophilic 704-silica material is firstly introduced for the fabrication of side-insulation film on the micro rod tool electrode by spin-coating technique. The 704-silica insulation film can effectively isolate the side of tool electrode with electrolyte. Micro 3D structures with uniform side-machining gap and small tape side-wall are machined. The surface with no heat-influence layer and 0.52μm R_a has been achieved.

Abstract: Groove milling is an important working procedure in plastic profiles manufacturing. Rational milling parameters have great effect on machining efficiency and quality. The milling characteristic of plastic profiles is investigated by cutting experiments in the present paper. The cutting forces increase with the feed speed increase. The vibration occurs easily in transverse cutting because of the low stiffness of the plastic profiles. When the feed speed is large, the workpiece material would produce softening and daubing phenomena appears subsequently on the workpiece surface which affects machining quality. It is therefore that the milling parameters are determined by the avoidance of cutting vibration as well as daubing effect at the same time.

Abstract: As environmental issues have become particular prominent, the theory of green designing has been a social consensus. Green packaging is definitely the future trend for the development of packaging industry. It is a significant step by deepening the people-oriented research on green packaging to solve the security risks in the process of designing and manufacturing of food packaging and to cope with the potential threat to human health and damage to ecological system.

Abstract: This paper introduces the basic working principle of capacitive micromachined gyroscope. A novel differential lengthwise capacitance comb detection structure is put forward. And it also analyzes the linearity of the differential lengthwise capacitive comb detection structure compares to the transversal detection. By measuring the scale factor, it verifies the high linearity of lengthwise differential capacitive detection structure. The linearity insures the linearity of conversing section of the detect system’s displacement and the capacitive variation. And this will greatly improve the linearity and stability of micromachined gyroscope.
