Abstract: With the development of electric vehicles in China, the demand on computing ability and storage for large-scale electric vehicle operation monitoring platform is increasing. Value-added technology of grid collaborative and proactive demand forecasting, multi-source data management technology, and storage technology of value-added services platform are new technology for the platform with the help of cloud computing. By using the new technology, the platform can provide powerful computing ability without substantial investment and make sufficient technical preparation for the extensive use of the electric vehicle.

Abstract: This paper is to research and design an open and modularization multi-function embedded NC platform. The platform takes ARM as the core, and using DSP chip to realize interpolation operation, abundant I/O ports and peripheral devices interfaces were designed, with high performance, cost effective and stronger universality features, easy to maintain and upgrade. User can add the special module according their need to achieve wire-cutting, lathing, drilling, milling and other operation and process of the NC tools.

Abstract: Prior studies show that self-motions early after a fracture surgery can effectively reduce the tissue viscosity. However, due to the postoperative pain and unawareness of the postoperative limitations, a patient prefers to take medication to alleviate pain while complicated rehabilitation exercises can only be implemented under the limited intervention of a therapist, resulting in the patient's lack of interactive feedback on a daily basis and a failure of self-motions to miss the timing of rehabilitation. Additionally, an assessment for the patient's amount of movements is usually carried out by questioning a caregiver by the medical staff during a clinical interview to organize the patient's self-report because an oral statement is more subjective and difficult to quantify the patient's amount and quality of movements, which may lead to the compiling results that can not be compared or referenced to, and may become a blind spot in the record in the current health care system. This study is intended to develop a lower limb fracture postoperative-guided interactive rehabilitation training system for the hip, knee and ankle joints, and establish a method of motion analysis and a method of motion performance assessment in conjunction with the wireless sensor technology and animation techniques, providing an objective assessment from the caregiver and learning the patient's rehabilitation status with a simple and easy recording means. Additionally, with the design of interactive feedback, the improved postoperative rehabilitations are tried to increase the participant’s interest in self-management of health and facilitate to keep tracking the rehabilitation information. The medical evidences show that a guided rehabilitation system can enhance the patient's motive and willingness to be committed to a rehabilitation training as well as increase Quality and Amount of the exercise activity during the training process.

Abstract: This paper works on the gracefulness of unconnected graphs. For the union-graphs of types of unconnected graphs, the conclusions are obtained as: for any positive integer m, n, assuming that G_{2n was a graceful graph edges at 2n, when 1≤n≤m , adhesive graph (Kn,m,G2n ) is a graceful graph; for any positive integer m,n,t where 1≤n≤m , and n≤t, unconnected graph Kn,mυ(G3}ν K_t)and K_n,mυ(P3ν K_t) are graceful graphs.

Abstract: This paper elaborates knowledge base construction of Poyang Lake regional library from its background to its measures and steps of constructing it based on theory and application of knowledge base. From the integration of resources to promotion of cultural construction and economic development,the paper propose the organization strategies and special database of the knowledge base.Finally, the paper emphasizes on discussing selection strategies and service pattern of Poyang Lake regional library knowledge base.

Abstract: Based on the study of the characteristics of scene graph and OSG, osgART and its application in product design was deeply analyzed. Organizational characteristics of scene graph, node traversal, interaction and update callback method in osgART were studied, and relevant codes were given. By adopting OSG scene graph to organize and manage scene information, the developments of AR applications with osgART can simply programming and increase application running speed. The real-time interactive capabilities of virtual objects with real environment can be enhanced, which meet the requirements of rapidly developing AR application with rich features. At the end of this article, a design review system with above approaches for product design was introduced.

Abstract: Steganslysis is an important research issue in information security. Aimed at the most commonly used cover media, digital images, the paper proposed a new method of universal steganalysis method based on multi-domain features. Features were extracted from spatial domain and DWT domain to overcome the drawbacks of steganslysis algorithm for specific steganography, such as high complexity and low correct detecting ratio. Experiment results show that the proposed algorithm can solve the low detecting problem and achieve a better reliability on low embedding rates.

Abstract: The paper presents the theoretical background and implementation details of a multi-domain symbolic analysis program developed with the emphasis on linearized hybrid systems combining classical electrical circuits, controllers, electro-mechanical converters and mechanical parts of electric drives. The systems analyzed can be composed of both basic elements and more complex behavioral blocks (regulators, converters, drives, etc.). All models are defined in an easily extensible library. Implemented algorithms for equation/matrix-based symbolic simplification allow obtaining symbolic expressions of acceptable complexity even for larger systems.

Abstract: The basic linear data structure of linear table data -- analysis of the physical structure of the two kinds of method: the linear order of the table to achieve and chain to achieve. The storage structure of insert operation, delete operation, lookup operation to study computer solutions. Compares and analyzes linear data structure of the physical implementation of the advantages and disadvantages.

Abstract: Against economic globalization backdrop, the government and scholars pay close attention to the e-commerce. Using the analysis tool--UCINET, the paper conducted an empirical analysis of E-commerce conference communication network based on social network theory. We have established an information database of Chinese E-commerce Conference, which reflects the relationships of conference communication network between them. Our findings are as follows: ①Some actors are in core position of the network, becoming the pioneers of leading the development of the retail industry network. But on the whole network, the network’s centralization doesn’t differ greatly. ②The communication network exerts a typical small world phenomenon. ③The conference communication network has no obvious phenomenon of "assigned" or "grade".
