Passive dynamic walkers are introduced  from the simple rimless wheel to the recently developed real two legged machines. Control strategies necessary to improve the stability and robustness of locomotion of passive dynamic walkers  such as the hybrid geometric approach and the virtual constraints  are discussed briefly. Finally  the unresolved problems in the field of passive dynamic walking are summarized and directions of further developments are discussed.

In this paper  an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented  which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation  and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart  which is closed to 1.5 times in ideal case. And also  the reconstructed and unreconstructed images are evaluated by the image information entropy  which proves that the reconstructed image contains more information. 2011 IEEE.   Experimental research on the deformation and failure of concrete under biaxial loading 会议论文  OAI收割 2011 International Conference on Electric Technology and Civil Engineering, ICETCE 2011, Lushan, China, April 22, 2011 - April 24, 2011 作者:  Lu MF;  Bai YL(白以龙) 收藏  |  浏览/下载：15/0  |  提交时间：2017/06/20 Biaxial loading  Biaxial loads  Boundary displacements  Catastrophic rupture  Experimental research  Fluctuation  Progressive failure  Two directions
