Abstract: Realize ozonation of the air by high voltage discharge using air in the warm room as raw materials. Ozone can quickly kill the ills in the air, on the face of the plants and Passivat virus. Therefore, one kind of warm room ills's ozone control machine of simply structure with easy operation and reliable performance has been developed. warm room ills's ozone control machine is a sterilization and disinfection equipment of no pollution and residue, which development and production to prevent and control warm room vegetable aeroborne disease, Is the best technology security equipment for the production of pollution-free green vegetables instead of pesticides. This product can also be used in sterilization fields of flower,edible fungus, storage and all kinds of water treatment and other fields.

Abstract: According to the present condition of ships design, draw lessons from and absorb design thought and technique of the maturity and the forerunner's ships, integrate to development means and design tool at present, put forward to the overall planning thought of the Ship lean R&D platform which is highly open, vivid, expansive and involved the whole ship lifecycle, set up the basic frame of terrace in the meantime. The platform with technique innovation, cooperation simulation and quality design for foundation, pays attention to accumulation and excavation of knowledge, support the integration and cooperation of core development business, and the full share of research resources with efficiently applied.

Abstract: Duo to the high cost of network entity equipment environment, network laboratory is not established completely in colleges and universities in china, students find that it is difficult to grasp the complex and abstract network concepts. Virtual learning tool software named Cisco Packet Tracer is free for students in anytime, which provides the same configuration environment as true network entity equipment. This paper presents the example of Dynamic Routing Protocol (RIP), and offers experimental design topology of RIP. This teaching mode not only reduces the dependence on the real environment, but also helps students to master the abstract network concepts and enhance theirs practical operation skills. This can cultivate student's innovative spirit.

Abstract: The current structure of fine-tuning the text watermarking algorithm against attack is not strong, poor robustness, this paper proposes a word-based encoding and character spacing feature combines text digital watermarking algorithm. This algorithm in the encoding process, a line of text in a word to the left or right horizontal embedded watermark information, and does not move adjacent words, the position of the decoding process as a reference, in the text character width adjustment embedding watermark information. Experimental results show that the algorithm has good invisibility and robustness.

Abstract: A sliding mode controller for buck converter based on PWM technology is discussed.Firstly, the schematic diagram of buck converter circuit based on a slidingmode control strategy is designed. Then a sliding mode control approach basedon reaching law is constructed. A circuit model based on MULTISIM is proposed.Finally, the simulation result show that the proposed method can effectively improvethe system dynamic characteristics.

Abstract: Combined with the stage-related characteristics in solving process of the Flexible Job-shop Scheduling Problem (FJSP) and the evolution characteristics of Genetic Algorithm (GA), a modified Adaptive Genetic Algorithm based on iterative generation and analysis of fitness values distribution is presented in this paper, which has both methods advantages. Instance simulation verifies that the FJSPs own characteristics are utilized in its solution by using the modified AGA, which overcomes traditional GAs limitation that initial stage of evolution is early and random search of medium-late stage is slow. Such methods are verified to accelerate convergence process, enhance searching efficiency and solving precision as well as avoid low efficiency and local optimum.

Abstract: This Delay/Disruption Tolerant Network(DTN) is a New Network Architecture for Communication in Restricted Condition with High Latency and Intermittent Connectivity.In Order to Solve the Problem that Messages can Not be Delivered Reliably because of Mobility and Limited Buffer Size of Nodes in DTN,a Probabilistic Routing Algorithm Based on Node Free Buffer-Utilization (NFBU)is Proposed.The Algorithm Sets Node Free Buffer Warning/excitation Threshold,through Warning/incentive Factor to Increase/decrease the Node Forwarding Probability,and Set up the Buffer Management Strategy,message Time to Live(TTL)value is Smaller,the Higher its Priority,at the same Time Remove the Oldest Message to get more Buffer Space.Simulations Indicate that the Algorithm Improves Delivery Ratio and Reduces Network Latencies in Different Node Free Buffer-Utilization State Compared with some other Routing Algorithms,and it is Highly Adaptable to Network.

Abstract: Most of the present finance software is designed by simply simulating the traditional accounting format, and automatically inherits its defects. This paper puts forward the defects that exist in the traditional accounting format. It also analyzes the enormous effects ERP environment has on the various aspects of accounting as well as the remarkable differences between the ERP environment and the traditional accounting setting. Finally, it points out that ERP accounting software is supposed to apply the advanced management and accounting concepts of ERP to the innovations of the traditional accounting format instead of simply mimicking the traditional accounting format so as to construct the new enterprise accounting informationalized model in the ERP environment.

Abstract: This paper focuses on the agriculture & supermarket interfacing and traceability model, on the basis of quality safety traceability model, and in-depth analysis the information technology of origin traceability subsystem, processing sectors traceability subsystem and storage links traceability subsystem, etc.

Abstract: In this paper, sensor scheduling algorithm tracking-oriented based on dynamic cluster and GDF is proposed. When the target run into the sensing filed of WSN, cluster is formed dynamically then Gaussian particle filter is used to predict the trajectory of target. With the target moving, some nodes are waked up to track the target and the others are allowed to sleep, so energy consumption is decreased remarkably.
