Abstract: Gear is essential in modern powertrain. While the overwhelming majority of existing gear's power transmission is relying on direct contact of the engagement mechanically, this paper is the study of a novel non-contact magnetic gear. The new structure is especially useful for the requirement of big gear ratio because of its high load ability. Such gear, with high research value, has many advantages over mechanical gears and may replace mechanical gears in many applications. Torque is so basic at factors such as mechanical work, energy consumption, efficiency, operating life and safety. For the basic mechanical components to transmit motion and power----- gears, the torque measurement and analysis seems of great significance in determination and control of load, working parts' intensity design and material selection. Torque analysis is a method which researchers could benefit from much, in order to clarify the practicality of this new gear, it is necessary to utilize theory of torque and the conclusions drawn from simulation to research the structure of this new gear situation. The study can clarify prospect of the gear and provide a theoretical basis for further design.

Abstract: For decades of research on triangulation, Scattered surface area triangulation has achieved some results, but a lot of algorithms extended to three-dimensional space still have some problems.In this paper I analyzes the existing algorithms and propose a idea based on the Combination of the incremental method and divide algorithm ,which directly realize the triangulation of scattered points in space. Through the triangulation of space scattered point ,it's result eventually meet the triangular mesh model of the reconstruction and the mesh is very uniform. The model reproduce the object model intuitively and clearly. This study provide meaning of the reference and guide in such a work

Abstract: The relativity was evaluated between dynamic modulus of elasticity (MOE) and static MOE, in order to assess the potential of using nondestructive testing (NDT) method as a checking tool for mechanical properties of wood-plastic structural plates. The dynamic MOE was evaluated on a FFT system, and the static MOE was determined by three point bending test. All of specimens were made of polyethylene（PE）and poplar flour. A significant correlation between the dynamic MOE and the static MOE was obtained from relativity analysis. These results suggest that the NDT method could be appropriate to estimate the dynamic MOE of specimens with different thickness.

Abstract: For the large computation workload of the adaptive filter algorithm and the low filtering speed of the adaptive filter model based on wavelet transform, a wavelet-based neural network adaptive filter model is constructed in this paper. As the neural network has the capacity of distributed storage and fast self-evolution, Hopfield neural network is used to implement adaptive filtering algorithm LMS, so as to increase the computing speed. The model applied to sEMG signal denoising can achieve a better filtering effect.

Abstract: The cladding industry has been experiencing a rapid development since two decades ago. The client’s requirements and architect’s ambition make the building cladding become more complex than ever before. The technical complexity calls for more comprehensive managerial techniques, especially information management. This paper proposes a web-based information management system, in which software package was developed and hardware incorporated. After establishing the framework initially, a main challenge, information sources, of this mechanism was discussed.

Abstract: In CAID software based on NURBS technology, the quality of curve directly affects the quality of surface, and the post-editing and modification of the surface, so good curve is the core and key to build high-quality surface. In this paper, combining the basic theory of NURBS curves with practical experience, we conduct an in-depth study in the method of controlling the quality of the NURBS curves, and propose an implementation to improve the quality of the NURBS curves.

Abstract: In this paper, the problem about establishing model of adaptive control in the optimal fishing strategy based on quantum control technique is proposed. An equation satisfied by fish stocks in a fishing conditions is obtained. Based on the stability analysis the question how to control fishing to the maximum sustainable yield and economic benefits is presented. The model of fish stocks growth in a fishing condition is established on calculus of variations. In the changes of fish prices, fishing cost, the inflation rate and bank loans, the fishing quantity is adjusted to obtain the maximum economic benefits through adaptive control methods and quantum control techniques. Analysis results have shown the validity of the proposed method.

Abstract: The safety menace of campus network is demonstrated and its network security is estimated in this paper, then combined with the development trend of future network, the necessity of deep inspection and intrusion prevention in campus network is analysized. Finally it puts forward and discusses thoroughly several representative strategies of disposing deep inspection and intrusion preventing in campus network.

Abstract: This study developed a designer-oriented smart home device computer-aided design tool that can help architectural designers to design smart home. This design tool is intended to incorporate smart home devices into overall spatial planning from the beginning of the planning process. Cloud computing [1] facilitates opportunities for online collaboration and coordination between individuals, between individuals and objects, and between objects, and will help speed the evolution smart home from centrally-controlled intelligent buildings to "smart living space" emphasizing distributed computation ability. This study employs (1) the theory of intelligent agents and (2) scenario-oriented design as an integrated framework for computer-aided design of smart home device. Smart home device are redefined based on agent theory. Agents' behavioral models include the five types of passive, reactive, active, interactive, and communicative; a comparison of these types provides a basis for the selection of home elements. Scenario-oriented design is employed to construct a smart living space (the AI. Living Lab.), which verifies the feasibility of the interface's operations. Finally, the resulting design methods and practical results are used to create a system development blueprint. Real life scenarios provide a basis for communication with smart home industry collaborators, enabling architectural designers to perform scenario modeling of a smart home proposal, quickly and conveniently establish a smart home information modeling system, and promote teamwork with smart home industry personnel.

Abstract: The research on monitoring and predicting drivers’ fatigue state has remarkable effect on prevention of traffic accidents, using the CCD image sensor camera as the image acquisition device of driver’s face and the 940nm infrared emitting diode as the light supplementary device and 3-points light supplementary had been utilized, the light supplementary system had been optimized by the experiment of infrared light supplementary which proceeded by means of combining the orthogonal experiment and expert fuzzy evaluation. The research result makes great sense to the monitoring of drivers’ fatigue state and traffic safety
