Abstract: Multidisciplinary design optimization (MDO) represents the development direction of complex products design theory and method, it shows a huge advantage in solving complex optimization problems in engineering applications, for example product design. This paper briefly analyzes some existing problems of small vertical wind turbine, and puts forward using the theory of MDO in small vertical wind turbine structural optimization. Then,the paper analyzes and points out the key technology of using MDO theory to optimize small vertical wind turbine, and provides a new train of thought for further in-depth study of small vertical wind turbine to improve the overall performance of the small vertical wind turbine products.

Abstract: Torque converter turboshaft is a hydraulic mechanical transmission devices of key components. In a new-mounted hydraulic mechanical transmission, super heavy laden vehicle during the test, the torque converter turboshaft fracture occurs when the vehicle traveling to 13 00 km, resulting in transmission power interruption, chassis parking problems. To achieve accurate positioning of the torque converter turboshaft fracture failure reasons, this paper analyzes the means of optical microscope and scanning electron microscopy, carried out on the fracture failure analysis, then using classical and finite element method to calculate the turboshaft intensity of the strength, and proposed optimization improvement program based on the cause of failure.

Abstract: There are many advantages in producing forklift box through the LFC. However, we found shrinkage porosity defects in the interior of castings through simulating the original process by ProCAST casting simulation software. Therefore, we analyzed the defects and improved the technology program. firstly, increased riser in position of shrinkage, Secondly, changed the filling’s way, lastly, selected the best temperature and vacuum by the orthogonal experiment and determined the best technology solution. we found the shrinkage porosity defects have been removed by the improved process. We found the production consistent with the simulation results through verification. Therefore we verify the accuracy of the ProCAST.

Abstract: In robot teleoperation, safety and operational performance are two important indicators. This paper presents a way to use virtual fixture to assist robot teleoperation and studies the realization method of virtual fixture assisting teleoperation in trajectory tracking, motion navigation and obstacle avoidance. The simulation experimental results indicate that virtual fixture method improves security and control performance of teleoperation system.

Abstract: The informatization of agricultural industry cluster promotes agricultural modernization. However, agricultural industry cluster in China has no real use of modern information technology. It does not form a rational application system and perfect frame structure, and also it has not reached in the true sense of "industrial clusters", further it influences the competitiveness of agricultural regional economy and the individual as a whole. We mainly study the model of agricultural industrial cluster information, combined with the realistic version of the "happy farm", by reference to the network of food pattern, to establish urban modern agriculture Demonstration Park. By SWOT analysis of the construction of the information platform model, we find out that information of agriculture ecological park to solve the main problems, the overall framework of information technology services of public building agricultural cluster model, focus on building the application function module of the realistic version of the "happy farm".

Abstract: Present a mobile payment Simulative system, in the process of paying, the system requires three parts to join in which are business server, paying agent sever and mobile client for users. Analyze the system flow, includes registration and login, confirm the identity information, submit orders, payment, fund temporarily custody, shipping the goods, user received the goods, payment complete and sellers get the money. Design the module, the system mainly includes the registration and login module, order management module, shopping cart module etc. Implement the functions of the Web browsing, commodity management, account management, funds management, send the bill and payment management on the bill.

Abstract: The purpose of the study is to solve the primary problem of the local government information. This paper analyzes the case of Yangyuan County, Hebei Province, China. We examined the current situation and investigated the problems of the construction information of the county government, analyzed the reasons and proposed the strategies.

Abstract: In order to improve the interoperability of XBRL format financial reporting on the semantic level, a novel XBRL financial reporting metamodel and a fact data semantic metamodel are proposed, which uses the Semantic Web technologies and Ontology theory. Then, a XBRL knowledge base is constructed based on this metamodel .Using the metamodel-based translation mechanism from XBRL to OWL / RDF, all the semantic information in XBRL taxonomy and instance documents is translated into OWL ontology and RDF instance. Finally, a knowledge base covering the semantic information of financial reporting domain is constructed.

Abstract: Fuzzy Analytic Hierarchy Process (FAHP) has been applied widely in risk measurement. In this paper, we have applied FAHP to the risk measurement of an e-commerce business. The results indicate that FAHP can reveal more details of risks. It is also helpful for the e-commerce businesses to improve their risk management process.

Abstract: Based on the common credit evaluation indexes system of the sellers for C2C, a fuzzy evaluating model is constructed based on Larsen criterion and the related algorithm is designed to evaluate the sellers. In this model, the indexes values are defined in continuous intervals and the internal relation between the overall evaluation and the sub-indexes is fully considered. So the credit characterization is close to the nature of the trading practices. Since the effect of the subjective factors on credit rating is efficiently eliminated in the calculation scheme, the credit grade got by the fuzzy algorithm is more reliable than the ones obtained by traditional methods. Finally, a numerical experiment is given to verify the effectiveness of the method.
