Abstract: Currently the studies on the effects of seismic isolation layer parameters on seismic response of base isolated structure are so few. So this paper used the software ANSYS to analyze seismic response of a reinforced concrete frame structure with openings slab. It focused on the relationship between the isolation layer of the elastic stiffness and isolation effect, and provided reference for reasonable selection of seismic isolation layer parameters.

Abstract: In the design of base isolated structure, the design of seismic isolation layer parameters is very important. Aiming at this problem, this paper using reinforced concrete frame structure of a partial discontinuity floor as an example, using ANSYS software, analyzed the dynamic characteristics of the based isolated structure, focused on the relationship between the yield stress of the isolation layer and the isolation effect, to provide reference for reasonable selection of seismic isolation layer parameters.

Abstract: Taking the frame structure of a floor partial discontinuity as an example, the paper using ANSYS software, analyzed dynamic characteristics of the structure, discussed the influence of floor openings size on the period of the structure, which provided reference for the design of floor partial discontinuity building.

Abstract: Taking the framework of a floor openings for example, The paper using SATWE software, analyzed dynamic characteristics of the structure, discussed the effect of the floor opening size on the mode participation coefficient. It provided reference for the design of floor partial discontinuity building.

Abstract: Architectural typology and configurations on the urban wind environment are closely related, this research took the large-scaled high-density development in Taiwan of Fujhou Affordable Housing as a case study, the use of computer simulation Ecotect Analysis, for collection of air distribution to explore central courtyard buildings wind environment flow in the urban environment for congregate housing. This study according to simulation results tried to adjust the configuration program for a further amendment to meet pedestrians comfort. Results proved that the use of computer simulation for design review, could effectively achieve the most optimized design while also to reduce energy conservation and improve comfort, which will further as references for future architectural design and master planning.

Abstract: Tulou (or "Earthen buildings") is an age-old type of Chinese vernacular dwellings. It is recognized by its unique architectural style and ingenious structure adapt to mountainous regions in Fujian province. In this research, we investigated the largest round type-- Eryi Lou-- which is designated as one of UNESCO World Heritage sites in 2008. In this study, we made site surveys for the dimension and the computational fluid dynamics (CFD)-based simulations to predict the wind field of Eryi Lou. In the CFD analysis, we considered the incompressible isothermal turbulent airflow to examine the interaction of the natural ventilation effected by its unique shape. The results indicate that the traditional round earthen building has superior performances in natural ventilation. This study may lead to a better understanding to the advantages of vernacular dwellings, which could be used to ecological architecture design in the future.

Abstract: In order to solve control puzzle of complicated characteristics for complex industrial object, the paper proposed an intelligent control strategy. First it made the anatomy and pointed out that the conventional control strategy is unsuitable to control the complex process. Based on comparison among control strategies, first it made decomposition and coordination for complex process, and then selected intelligence based control strategies, finally adopted human simulation intelligence based control algorithm to implement the optimization control of complex process with uncertainty. The simulation effect demonstrated that it is faster in response, high in control accuracy, and strong in robustness. The simulation shows that it is a wise choice to apply the intelligent control strategy for complex industrial process with uncertainty.

Abstract: In order to solve the puzzle of parameter tuning of the controller in complicated system, the paper proposed a model of parameter tuning based on immune principle. Firstly it defined the antibody, antigen and affinity in tuning parameter needed, secondly explored the process of parameter tuning based on immune principle in detail, thirdly discussed the tuning method by means of optimizing parameter of the controller. And finally it took the control of high-order process as an example, and made the simulation to a highly non-minimum phase process. The simulation result shows that the proposed method is better in control quality and more effective compared with other tuning methods.

Abstract: Along with the rapid development of correlative technology in the 21st century comes the upsurge of research and exploitation for stratospheric airship around the world. In this paper, on the basis of the unique strengths of stratospheric airship, we analysed its prospects of application in the fields of communication and earth observation. Besides, we explored the status quo of development and key techniques concerning the stratospheric airship, which lead a significant role in the reference and guidance for future development of advanced information technology and building of national defence.

Abstract: Malfunction such as target non-reach ability, local minimum pole and oscillation happens when traditional APF is applied to route planning. This paper proposes an improved APF model, considering the relative distance between the UAV and the target, the relative distance between the lead craft and the wing craft and the safety. We ensure the point of target to be the global minimum point in the entire potential fieldtarget non-reach ability caused by the threat and target point being too close are solved by adopting the modified repulsive potential function; planning failure in which UAVs falling into local minimum point is solved by adopting random fluctuation method; considering the oscillation of traditional potential field, the obstacle link method is proposed. The results of the simulation indicate the single UAV simulation route after obstacles overall planning, track route of UAV formation and formation route with obstacles with turning angle constraints. Requirements of Formation control and formation obstacle avoidance have been well satisfied.
