Abstract: Along with the developing of information technology, Java platform a plays more and more important role in building enterprise information system. Especially after the cloud computing emerged, Java applications are used as kinds of services to provide the users some function. Users use these services remotely, and the applications should give the users some trust evidence. Control-flow integrity endows the software the ability to show the applications' behaviors conform to the users' expectations. But the Java virtual machine's memory organization is different from physical machine and hinders the application of CFI. This paper gives out the a novel way to enforce the control flow integrity to the Java applications based on the memory organization of the Java virtual machine. The method presented in this paper can provide the user information about an applications behavior, and significantly improve the security of a Java application.

Abstract: Based on metadata technique, this paper introduced metadata service oriented multi-source heterogeneous information data integration frame for large multi-source heterogeneous information integration management and interconnecting, intercommunicating, interoperability between different heterogeneous information systems. This metadata service oriented frame, benefiting from knowledge base of data warehouse, had 5 layers frame system including resource layer, integration layer, management layer, service layer and customer layer. Metadata service system contained data layer, directory service logic layer, data exchange layer and Web presentation layer. This paper represented that the metadata service was the core of integration frame, and the realization of integration management platform was feasible.

Abstract: Aiming at the inherent deficiencies of large-scale wireless sensor network for positioning technology, the DV-hop algorithm is mainly studied and improved, and two kinds of improved algorithms DV-hop and DV-hop+Lastdist DV-hop-MinMax are proposed, and can select the appropriate algorithm according to actual application environment. Finally, the paper gives the method to realize OMNeT + + in the simulation environment, and carries out the simulation analysis.

Abstract: In view of the problems in the current domestic and international remote wireless meter reading system, propose the remote wireless meter reading terminal system based on ZigBee technology combined with GPRS technology, carry out the hardware circuit design of each module, establish ZigBee wireless meter reading network based on 802.15.4 layer networking protocol, design a more practical remote wireless meter reading protocol and data transmission format. Test results show that it has realized the formation of ZigBee network, collection and remote transmission of meter data, terminal equipment parameters modification and other functions to achieve the terminal design requirements.

Abstract: A design of image data cache system based on Nios II/(s) high performance soft-core processor is presented in our study. The FPGA, the image acquisition chip, the Nios II/(s) high performance soft-core processor, were selected together with the memory constitute the designed system to realize the prospective function. The principle of each specific function module in our study was discussed and analyzed, and the design of software and hardware were more perfectly. We found that the designed system presented an excellent generality, feasibility, reliability during the test course, which can be used in integrated sensor networks for environment and tracffic monitoring in urban areas.

Abstract: Retracted paper: In recent years, much research has been devoted to the emulation of the Turing machine; unfortunately, few have simulated the emulation of the partition table. In fact, few cyberneticists would disagree with the construction of symmetric encryption, which embodies the structured principles of algorithms. We propose a novel heuristic for the synthesis of linked lists, which we call Carl.

Abstract: XML query processing needs to search an XML document and return results that satisfy a request. In this paper, we proposed an effective pattern match algorithm based on structural index. This algorithm uses a suitable labeling scheme and an efficient structural index by identifying parent-child, ancestor-descendant and sibling relationships among nodes. Due to the algorithm avoids invalid immoderate results to be pushed stacks, So, It reduces the amount of joint and improves the performance of Query. Experiment results proved that our algorithm, TwigM performs about 15% better compared to TwigStack [ and 10% better than TwigINLAB[ for all types of queries.

Abstract: The mechanical arm is a multi-input multi-output, highly non-linear, strong coupling complex system. Active Disturbance Rejection Controller is of good performance and relatively simple algorithm. Artificial Bee Colony algorithm is a new swarm intelligence algorithm based on the behavior of honey bees. The linear ADRC was adopted to realize the moving control of the mechanical arm and the controller parameters were chosen and optimized by ABC algorithm. Simulation results are satisfied and well prove the feasibility and validity of the algorithm.

Abstract: This paper proposed a new OLAP model and a cube coordinate cell algorithm. This algorithm can quickly and accurately calculate the coordinates of the cube cells and quickly find the appropriate data.

Abstract: This paper involves the modern agricultural application control system which is based on internet of things, and this intelligent management system uses intelligent control technology such as S7-300, GSM,WSN and Zigbee to realize the modernization of rural security, agricultural production and residents living fully intelligent managed. This system applies precision agriculture, digital image processing, wireless data transmission and other fields, really combining digital management technology with embedded technology. At the same time, this system which is based on internet of things is the necessary path of modern agriculture informatization strategy. With the mature development of technology of internet of things in modern society, modern agriculture application management system based on internet of things will bring new change to agriculture and high efficiency of agricultural production.
