Abstract: This paper mainly studies at the different way of ventilation to the influence of air distribution in the large size plenum. The model is a grand theatre stalls. To model the plenum which under the grand theatre stalls,and took out the size of large mutations alone modeling and studying it. the six different way of ventilation: small plenum with four directions supply air; Take a duct with four tuyere on supply air; Single tuyere withside air supply; Tuyere parallel supply air; Single tuyere with air supply under; Take a duct with four draught under supply air have influence of air distribution.And combined with the well of heat insulation in the large size plenum.It can use the standard RNG turbulence model, and the pressure interpolation adopt standard discrete format, the convection item of the momentum equations, k equation, ε equation adopt with second order the format. the pressure speed coupling adopt Simple algorithm. Finally through the FLUENT software were used. It can use the air balance coefficient wich is one evaluation index to analyz Simulation results of the Six air distribution mode . Through the analysis and comparison with a wind that four tuyere air supply under Static pressure boxair supply the best effect, the static pressure air distribution most evenly

Abstract: Aggregation of systematic operational capability of armaments is significant for armaments systems' developing, constructing and using. As holistic avalanche and operational capability's nonlinear character of armaments systems, the feedback mechanism among capability indexes is researched and an aggregate method of systematic operational capability based on feedback mechanism is proposed on this paper, what's more, the method is proved effective by certain example of reconnaissance intelligence armaments systems' operational capability aggregation.

Abstract: With the development of mechanics and computer technology, computer simulation has become an important tool in the hydraulic system analysis and design. The application of computer simulation technology in hydraulic system is introduced in this paper. A hydraulic servo system was modeled by standard procedures. By simple operation of the software, named MATLAB/Simulink, dynamic characteristics of the hydraulic servo system are simulated. The result of the simulation verifies the validity of the method, which is applied in research.

Abstract: This work describes the development of a novel equipment support training system. Differing from the traditional teaching panel method, the proposed method does not require any complex computations for coordinate transformation and is a simpler scheme. The proposed equipment support training system includes small equipment support training robots. The system specification phase determines the basic functionalities of the system, which can be described as a series of multilevel goals. Interface analysis is used to understand the input and output interactions between the system and the environment. The equipment support training system architecture, control board design and program flowchart are described and implemented.

Abstract: Electric vehicles use lots of ECU controllers in the CAN network, the quality of ECU parts used in vehicles is closely related to safe driving. This paper develops a kind of fault diagnostic equipment for electric vehicles ECU controllers. This device has designed digital input signal acquisition module, the output switch signal module, power supply module and fault simulation module based on CAN bus communication principle. Then we use LabVIEW developing computer program in order to monitor and control the whole system.

Abstract: Numerical method is used to build the entity model and finite element model of a marine pump, modal analysis shows that modal frequency is not equal to the operating frequency and the resonance is not produced in the pump. The finite element method is used to calculate the shock load which is the request of GJB. The allowable strength at vertical, longitudinal and horizontal direction of the pump is analyzed, and the anti-shock behavior of the pump is checked too. The results show this type pumps are not destroyed wholly and can be working normally in the shock environment, which satisfy the requirements of GJB. But the bracket position of the pump is suffered great compressive stress which leads to the designed and strengthened again.

Abstract: This paper presents a hybrid algorithm for the hot rolling scheduling problem, which is derived from the actual steel production, and some features make the solution methodology more difficult. The hybrid strategy is based on the solution construction mechanism of estimation of distribution algorithm (EDA) with path relinking (PR), an evolutionary method, which results in a novel approach that we call EDA_PR. Moreover, a decision support system in which the algorithm has been embedded for the hot rolling scheduling is designed. The computational experiments show that the EDA_PR method has more potential for improvement to solve the hot rolling scheduling problem compared with the manual scheduling method.

Abstract: Intelligent power utilization is an important part in the construction of smart grid, its outstanding characteristic is interaction between power grid and demand side. Based on the demand of family intelligent power utilization, this paper analyzes the significance of bilateral interaction system construction, proposes the design scheme of interactive family intelligent power utilization system to satisfy the users various and individual demands, designs intelligent display client software. The system integrating power flow, information flow and business flow is established in order to support new power supply and demand relationship between grid and users and ensure the QoE (Quality of Experience) and optimize the configuration of assets of power grid.

Abstract: Mapping automation is not only a key objective of cartology, but also a study hotspot of geo-spatial information science at present. Here, we take thematic mapping of river channels (pipelines) passing through Yunnan in Kunming City for example to study and discuss, with regard to the effect required by complicated mapping encountering in the process of project implementation and the requirements on high quality of mapping data, the representation of rule-based data-driven computer mapping by the Representation technique of Arcgis9.3 to partly accomplish such mapping task that needs a lot of manual editing in traditional mapping mode, especially achieve the some kinds of mapping effect that cannot be achieved by traditional mapping without destructing GIS spatial information. The findings indicate that, the representation technique of rule-based driven computer mapping can reflect the advantages of both GIS spatial database establishment and mapping. This technique can make map rapidly according to different data requirements, and achieve the effect of traditional mapping. Due to less demand on manpower and financial capacity, such technique has a broad prospect of promotion and engineering application.
