Research on Ride Comfort of Half-Rotating Walking Mechanism Wang Xiaoyi a, Liu Jingliang b, Chen Fuqiangc, Qiu Zhizhen d School of Mechanical Engineering, Anhui University of Technology, Ma’anshan, 243002, P.R.China awangxy@ahut.edu.cn, bliujingliang324@163.com, ccfq@ahut.edu.cn, dqzzhlx@ahut.edu.cn Keywords: Biped walking mechanism, Half-Rotating Mechanism, Ride comfort, Motion analysis, Optimization design Abstract: Bionic walking mechanism is an important part of bionic motion machinery.
First-level and second-level rotating arm are the key transmission components which could generate asymmetry movement.
This shortcoming could be overcome by installing feet with suitable elastic material and controlling appropriate angular velocity of driving shaft. 4 Conclusion HRWM is a new mechanism with obvious characteristics of biped walking.

Research and Implementation of Remote Sensing Image Vectorization Haiyan Wu College of Computer and Information Engineering, Zhejiang Gongshang University,China why@mail.zjgsu.edu.cn Keywords: remote sensing image vectorization; edge enhancement; boundary tracking Abstract.
Edge tracking is the final step in the process of vectorization, it is particularly critical step, according to the given features in seed point automatically track the boundaries of material, and to set the boundary points into the ACCESS database.
the key technology of integration based on coordinated decision centra Border is the most basic features of the image, they are a set of pixels that existed gray-scale contrast changes around the image segmentation, it is a important foundation for texture analysis and image recognition.
