Abstract: The key technology for widen continuous hollowcore slab bridge with long unit is improved. Taking Taiping flyover in Guangshen highway as an engineering background, the principles of splice joint are given, extension schemes are analyzed and compared in this paper. A reasonable scheme is decided finally and a 3D finite element model is established to check if the structure is satisfied with the requirement form the codes. After the extension project is finished, a local monitoring is carried out, including monitoring for stress and settlement. Both the calculated result and the test result are in acceptable range and satisfied with current codes. The research shows, the rigid joint structure adapted in this paper is reasonable.

Abstract: Internet of Vehicles is the basis of the application of intelligent transportation system .This article has carried on the analysis and discussion about the concept of IOV, overall structure and the key technologies which are desperately need to be solved to promote application and development of IOV system.

Abstract: Saas is an abbreviation for Software-as-a-service, it is a completely innovative software application mode provided via Internet. As a new IT service model, SaaS has two sides. This article focuses on analysis the existent security risks of SaaS and put forward a series of countermeasures and suggestions to address these issues from the technical aspects.

Abstract: With the development of computer technology and network technology, people want to design clothing which meets the aesthetic personal requirements through more convenient and more efficient computer technology. At the beginning of 21st century, customized electronic system came into being, it organically combined the human modeling in clothing production, body analysis, all aspects of the anthropometric fashion design, style selection, ordering clothing, apparel production by using the modern three-dimensional body scanning technology, computer technology and network technology to achieve effective and efficient digital garment production.

Abstract: A mobile identity authentication scheme of e-commerce based on proposed to solve the problem that present merchant system's digital certificate carrier is not convenient to carry and specific device can only be used for' specific service. Java-SIM card technology has optimized PKI operations, and supports multiple applets running independently and securely on one card. Using the java-SIM Card to store private key and do digital signature operations, users can conveniently and securely enjoy any merchant's any online transaction service.

Abstract: The wide application of the technology of the Internet of things has promoted the information society and improved the efficiency of our lives. But the heterogeneity of the strong coupling expansion of capacity and poor, high and networking equipment and application platform fragmentation made the matter long development cycle and a higher threshold status networking appear. In response to these problems, the article studies on the architecture and key technologies of web of things and designs the architecture of WoTSE model.

Abstract: The paper constructs an evaluation model for practical teaching quality based on Back Propagation (BP) neural network. It makes the indicators of evaluating practical teaching quality as input data, while practical teaching quality as output results. The empirical conclusion obtained from the use of Excel is that BP neural network is suitable for practical teaching quality evaluation and also makes a better analogy to the experts’ evaluation process. The results are satisfactory with wide application.

Abstract: Automated Mechanical Transmission achieves automatic shifting by applying electronic control technology in traditional dry clutch and Manual Transmission,not only having the advantages of automatic transmission, but also keeping the performance of the original manual transmission. This paper generally introduces the function and performance characteristics of Automated Mechanical Transmission, and elaborates its system structure, working principle and key technology. The key technology is divided into 4 parts, including Electronic Control System, Clutch Control, Shift Strategy and Design and Optimization of the Actuator. Combining with the related companies' research and development products, the performance of the Automated Mechanical Transmission is further analyzed. At the same time, according to the current research status in the world, putting forward the following research focus and development trend of Automated Mechanical Transmission.Keywords: Automated Mechanical Transmission; Key Technology; Development Trend
