Abstract: According to the characteristics and needs of virtual scenic roaming system, select the appropriate modeling techniques. By using the modeling platform scenic entity object model structure, and then build virtual tourist attractions, we propose hierarchical collision detection methods. This method actually meets the accuracy requirements under the premise, greatly reducing the number and complexity of collision detection; effectively improve the system in real time.

Abstract: The implicit function theorem and the mean value theorem non-affine function of the system into an affine form, and then RBF neural network approximation virtual control and actual control signals desired. Finally Lyapunov functional theory and backstepping method are used to design a self-adapt tracking control scheme. The proposed control scheme can guaranteed to achieve better tracking performance, thus avoiding the problems caused by the high-gain control affine term sector caused by design problems and overcome loop controller. In order to solve practical engineering control problems provides a theoretical basis and can learn from the ideas, and finally through numerical examples to demonstrate the effectiveness of the proposed method.

Abstract: This paper describes the frequency electrostatic dust-phase power design, triggered by SCR phase control method to achieve closed-loop control of three-phase AC voltage regulator of the main circuit, designed three fold spark for spark control tracking control algorithm. Electrostatic precipitator and main circuit power supply is simulated, and the main circuit parameters were calculated, the results show that the system can be better used in industrial environments dust.

Abstract: The application scheme of Campus Smart Card System is analyzed, and its design aim and development principle of the functional modules are introduced. campus smart card system on 3G technology which is one of the important parts in campus digitalization. It offers comprehensive data collection and excellent information sharing environment. Its realization will promote the information management of the school and increase construction process of digital campus.

Abstract: Warehousing management in the context of supply chain involves various products, requiring product information to be accurate and punctual. However, it is the inherent defect of the existing warehousing management system that hampers the improvement of warehousing efficiency. Thanks to its plentiful advantages, IOT (Internet of Things) represented by RFID technology can significantly improve the efficiency of warehousing. In regard to the application of IOT to supply chain warehousing management, the author proposed corresponding analysis and design scheme.

Abstract: The Yellow River Delta National Agricultural Science and Technology Park proposed the concept of "One Zone One Hundred Parks", namely the Yellow River Delta National Agricultural Science and Technology Park consists of a hundred geographically dispersed agricultural technology demonstration park. In order to effectively provide intellectual support for these geographically dispersed agricultural technology demonstration parks, this paper presents the design and the idea of remote crop image capture and expert systems. The core idea is to set up image collection terminals in a decentralized agricultural technology demonstration park. Crop samples are collected by the terminals, using GPRS network to transfer the captured image data to the Key Laboratory of Agricultural Bioengineering. Agricultural experts make an analysis to image samples, and propose treatment advice. And then, the experts feedback the advice to the various agricultural technology demonstration parks. After a year of testing, the entire system is reliable, excellent performance in real-time transmission of images. This system has played a very important role in the prevention and control of crop pests and crop growth guidance.

Abstract: The application of virtual reality technology is a hyperlink on a web, multi-user interaction, computer platform-independent modeling and rendering three-dimensional graphics technology. Dressing is using three-dimensional virtual reality systems such real-time, via the user with the mouse or keyboard to control the direction of view, the scene model arbitrary move and zoom, real-time rendering every angle view of the effect of wearing apparel. This study mainly done for the creation and analysis of three-dimensional human data fitting system, three-dimensional three-dimensional body.

Abstract: Middleware supports programming abstract which facilitate the programmer task and bridge the gap between the application and the hardware. Middleware for wireless sensor networks (WSNs) can help bridge the gap and remove impediments. This paper designs GWSN, a middleware WSNs, whose architecture is composed of runtime support, application development kits, and software development kits. Runtime support in GWSN is the core of WSNs middleware and supports executing and maintenance of WSNs applications. Application development kits includes many basic function kits, such as display editor, rule editor, and workflow editor, which support the application development of WSNs. Software development kits provides easy-to-use application programming interface.

Abstract: Service robots are increasing significantly, as they are playing a key role in our city-life. This paper depicts the system design of a beverage-sale robotic system named BSR. BSR can sale beverage such as Coca Cola, beers and Sprite to the clients automatically, working as a human seller. The robotic system can also play the role of a casher doing cash in and check out. In this paper, the hardware design including the mechanical structure and the electrical system are introduced firstly. Then, the control strategy is proposed. BSR has been exhibited in a science museum in China and it is well welcomed by the audiences.

Abstract: This paper depicts the system design of a basketball-playing robot named BPR. BPR is a wheeled mobile robot equipped with a 3-DOF manipulator and a mechanical claw. The robot can grasp one basketball and then dunk under the players remote control. In this paper, the hardware design including the mechanical structure and the electrical system are introduced firstly. Then, the kinematic analysis of the manipulator is proposed to decide the manipulators posture control. Finally, simulation of the manipulator is implemented in ADAMS to verify the design efficiency of posture planning. BPR has been exhibited in a science museum in China and it is well welcomed by the audiences.
