Abstract: In order to integrate various digital identity management systems in the context of large enterprise organizations which have a variety of digital identity management system, this article defines the digital identity management strategy, proposes a digital identity centralized management platform architecture and highlighted several key technical considerations. The security level of access to network resources could be increased and the incidents of identity fraud and economic losses could be reduced through centralized management of digital identity’s life cycle and usage. Centralized digital identity management can not only increase the information management maturity but also support organizations’ information technology development.

Abstract: This study describes an exercise training case after stroke that can be remotely controlled by a therapiest, and the pilot clinical test result of rehabilitation platform. We have developed a set of training mission with graual difficulty in the virtual environment game, and the process includes delicate hand action and entire upper limb action, meanwhile, the operation patient and the therapist will stay at different room for the training. In the study, social psychology variable is used to assess the process of human machine interaction, thue result shows that after using this rehabilitation system, the negative feeling is significantly reduced (Confused feeking, t(13)=2.54, p<0.05, anxiety feeling t(13)=2.58, p<0.05, pressure feeling, t(13)=2, p<0.1). The entire satisfaction shows positive relationship with the feeling cooperating with the therapist (r(8)=0.770, p<0.05). Using this rehabilitation system case, it was found that the active emotion before carrying of rehabilitation therapy shows positive relationship with the continuous participation of therapy after rehabilitation therapy process (r(14)=0.699,p<0.05), that is, the research shows that rehabilitation significantly enhance the psychological state of the stroke case.

Abstract: With the rapid consumption of resources and heavy air pollution caused by traditional vehicles, Electrical Vehicles(EVs) have become more and more important than any other time. However, the network management of traditional vehicles can not meet the requirement of EVs. The paper proposes a network structure of EVs which can effectively and separately control the state of the network segment. The network comprise several segments which communicated with one another by at least one gateway. In this paper, 4 working modes of EVs are defined, the network manager(gateway) can switch its subscribers on or off the line depends on its working mode. The network management proposed by this paper has advantage of more effective controlling and reduce power consumption. To verify this method, the simulation is set up and the test result testifies the reliability and validity of the network management.

Abstract: To promote the process of normalization in distribution network live working. This paper research and development a tree-dimensional simulation training system on 10kV distribution network live working by virtual reality, this system visually reappear operating methods and workflow of distribution network live working by tree-dimensional animation simulation, it is appropriate for training the distribution wire professionals, and satisfy the needs about speedy network construction; meanwhile this paper based on national standard of distribution network live working and distribution network live working practical experience of Guangdong province electric power company, the designed tree-dimensional simulation training system is apply to the specific projects in the city of Dongguan , the projects run well verify this system is feasibility and validity.

Abstract: To solve virtual access to distributed oil-gas field data, a new distributed data access model is used to virtual data access center integration platform in oil-gas field.By introducing multi-task cooperative agent (MTCA-DDA), collaboration of MTCA-DDA can efficiently solve distributed data access collaboration problem. Failure server scheme guarantees distributed data continous access. Periodic exchange and data cache mechanism greatly improve data distributed store and access speed.Virtual data access center integration platform shows MTCA-DDA model can improve data access efficiency and enhance the reliability of data access.MTCA-DDA model with periodic exchange and data cache can effectively solve storage and reliability of massive distributed data access and provides a new way for similar distributed application.

Abstract: Internet of Things (IoT) is an important support for smart grid, and the smart grid is an important application of the internet of things. In recent years, the smart grid was listed in one of the top ten applications of IoT, and the development of IoT in power grid by the concerns of the community. This paper first introduces the basic connotation of the IoT and analysis of the shortcomings of the current power development of the IoT. Combined with the planning and operational characteristics of smart grid, the development stage, hierarchical research and the key technology are summarized. Finally, we look forward to an advanced form of IoT in power grid.

Abstract: TD-SCDMA system can dynamically allocates time slots between uplink and downlink according to local service requirement, which causes cross-slot interference if adjacent cells have different direction links in the same slot. Because of the specialty of cross-slot interference between base stations, traditional methods which subtract interference in digital baseband don’t work well. A novel method is proposed. Simulation indicates that this scheme can effectively reduce the cross-slot interference.

Abstract: The collection and storage of target information has been one of the core technologies in the modern technology and industrial development. The paper designed a system solution for the collection and storage of target information based on the ARM platform. It can get real-time target information by the use of the double positioning models of GPS and Beidou satellite navigation system. It designed and implemented real-time storage of target information using SQL 2000 database. Information can be not only showed on the ARM platform, but also remotely queried through the Internet. It will be a great significance to track a target and exploit AIS equipment.

Abstract: The demonstration system of tobacco monitoring by remote sensing was made with use of the characteristics and advantages of 3S technology. This paper describes the function of the system design ideas and main display functions such as estimation planting area of tobacco, monitoring tobacco growing and yield estimation of tobacco. The key technologies of the system are data acquisition, preprocessing and data organization.

Abstract: Localization is an important process in wireless sensor networks (WSNs). In this paper, we present a localization algorithm based on triangle grid scan (TGS) method. The objective of this research is to provide an affordable mean for localization using wireless area network Wi-Fi technology with mobile robot. Experimental study reveals that the proposed TGS mechanism effectively guides the mobile anchor to move along an efficient path.
