Abstract: The evaluation for supply chain risk is very important to show the latent risk and eliminate the risk. In the study, Bayesian network is proposed to evaluate the supply chain risk. The assessment indexes of supply chain risk are analyzed before supply chain risk assessment. Then, the assessment indexes of supply chain risk can be used to construct the supply chain risk assessment model. We apply a certain logistics company to study the evaluation ability of Bayesian network evaluation model proposed here. The experimental results prove the effectiveness of the proposed model.

Abstract: With the rapid development of the Internet, EC is growing rapidly. The use of information technology to transmit and process business information has inevitably brought the defects and shortcomings of its own into the field of EC.The security issue is becoming the primary factor restricting the development of electronic commerce ,and is the most important issues related to EC system can be run successfully. EC security issues can be basically divided into two parts, namely, computer network security and business transaction security. The paper discusess these two parts and gives the countermeasures in the last.

Abstract: Via examining the evolutionary phenomena in biology, it is known that the evolution of life is based on the fact the variation of species is caused by the alteration of the DNA code sequence. If we assume the DNA molecular chain is a program code sequence, similar to the modern computer program code sequence, then the evolutionary phenomenon in biology can be simulated and it will be bring out an Evolutionary Programming Model (EPM). The main idea of this model lies in the two key conception: First is that two copies of the program code sequence in memory were loaded, then put one in the running status and the other in non-running status. Second step, use the reflection calculation to perceive the environment and adjust its functions in the running one. Then use Bytecode Engineering Technology to locate and modify the corresponding code segment of the non-running one, and consequently generate the next version program. This process can be repeated as needed, similar to the evolution of the DNA sequence in Nature. EPM enables the program to "sense" the running environment, to make corresponding adjustments in order to accommodate the running environment, and to generate the new version program at the same time. The EPM model will have widely application prospects in the field of artificial intelligence and is extremely important in guiding the future automatic program design and robotic evolution design.

Abstract: Chinese train control system is abbreviated as CTCS. And there are five levels in CTCS, and CTCS-3 is used for the high speed railway which includes the long rail lines, the different regions, and the rich variety of scenes. It is very important to describe efficiently the relation of the objects for the design and the modeling of the railway visualization. This paper proposes the multi-resolution modeling of CTCS-3 visualization based on meta-model, and introduces the formal description of this meta-model by XML. The formal description examples have certified that this method can provide the enough grammar rules for the reusability of CTCS-3 visualization model.

Abstract: Nowadays bungee jumping is a popular extreme sport. Bungee jumping can be simulated with a continuous Simulink model. Exact measurements and calculations can be done to keep the jumper from striking the ground and to avoid other accidents. The Simulink model of bungee jumping system is built and its safety is analyzed. In this paper, an open experiment platform which has flexible selection of time, contents and evaluation methods is introduced to improve students’ ability of practice and innovation.

Abstract: Based on the splicing of knitting and tatting fabrics and the optimization of process realization route, the author tries to improve the drawbacks in traditional splicing of knitting and tatting fabrics in terms of process technology and thus extend their respective advantageous properties. Through the analysis of fabric properties difference, integration of structural characteristics of parts, optimization of sewing process and post-production process reengineering, the author proposes the prerequisites and principles related to the splicing of two fabrics, and discusses the common problems in the splicing of knitting and tatting fabrics and specific process optimization route.

Abstract: Outdoor clothing may vary multiple styles by means of opening, closing or replacing zipper and display different exterior profiles and functions in order to better satisfy the needs of outdoor activities. Using zipper as the transformation medium in synchronous transformation experiment for outdoor clothing and bag in style and function, this study realizes the perfect combination of practicality, functionality, aesthetics and enjoyment of products, extends the design concept of functional outdoor clothing and gives suggestions on ecological development of outdoor clothing.

Abstract: This research work involves the dyeing of silk fabrics with cochineal inset, Safflower yellow, gardenia blue, three kinds of natural dyes. Then, UV protection performance was analyzed. The results show that the fashion color that turquosice has been acquired through changing the proportion of each natural dyestuff in combination dyeing, simultaneously there will be a certain influence on the movement comfort performance.

Abstract: This paper proposed the floating thread defect detection method base on wavelet entropy for tufted carpet. The method first get the image from cam and preprocesses the captured image with filtering, then using Wavelet Entropy to judge whether there are defects in the image. For image consist of defects, apply further thresholding operation to the image. Closing operation was adopted to eliminate noise and highlight the defects. At last, nine samples image were tested to verify the feasibility of proposed method.

Abstract: This paper put forward a new kind of motion energy expenditure calculation model that combine movement heart rate, acceleration, height, gender, age, weight and other personalized parameters. In this model, using heart rate and personalized parameters to calculate the based energy consumption (BEE). Using acceleration and personalized parameters to calculate the movement work (EE_act). The experimental results show that this method has a high accuracy in movement energy expenditure. So using this method can eliminate the contradiction between measurement accuracy and measuring cost.
