To conclude that the effect of angular displacement was the major factor. Allowable MTF degradation was represented  and 34dB reduction was achieved at frequency of 100HZ. With the help of MSC.ADAMS simulation software  and convert allowable MTF degradation into stable system design parameters  simulated curve proves correct for isolator  which can guide perfect design for stabilization system. Based on the spatial mechanism and translational principle of parallelogram  and the irrotational displacement mechanism was tested by optical method  an irrotational displacement isolator was developed. It can meet the requirements of irrotational displacement and damp. An instance was given  coupled angle is less than 8?  it can satisfy the demand of aerial imaging.

In this paper  we propose a new method for generating progressive animated models based on local feature analysis and deformation area preservation. We propose the use of solid angle and height value for a non-hyperbolic vertex to define the local feature parameter. This local factor is embedded to the vertex quadric error matrix when calculating the edge collapse cost. In order to preserve the areas with large deformation  we add deformation degree weight to the aggregated quadric errors when computing the unified edge contraction sequence. Finally  a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast  easy to implement  and as a result good quality dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.   Manifold functions of the Nail-Patella Syndrome gene Lmx1b in vertebrate development 期刊论文  OAI收割 DEVELOPMENT GROWTH & DIFFERENTIATION, 2009, 卷号: 51, 期号: 3, 页码: 241-250 Dai, Jin-Xia; Johnson, Randy L.; Ding, Yu-Qiang 收藏  |  浏览/下载：27/0  |  提交时间：2012/07/13 isthmic organizer  kidney  Lmx1b  nail-patella syndrome  serotonergic neurons  DORSAL SPINAL-CORD  CENTRAL SEROTONERGIC NEURONS  TRANSCRIPTION FACTOR LMX1B  MIDBRAIN DOPAMINERGIC-NEURONS  FORKHEAD/WINGED-HELIX GENE  SAETHRE-CHOTZEN SYNDROME  OF-FUNCTION MUTATIONS  OPEN-ANGLE GLAUCOMA  ISTHMIC ORGANIZER  TISSUE INTERACTIONS   Shape and alignment measurement of the heliostat by laser deflectometry (EI CONFERENCE) 会议论文  OAI收割 Optical Modeling and Measurements for Solar Energy Systems II, August 13, 2008 - August 14, 2008, San Diego, CA, United states 作者:  Liu H.;  Zhang H.;  Zhang H.;  Liu H.;  Liu H. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 In the solar tower thermal power generation system  such apparatus and corresponding software packages are developed. With the help of these two apparatus  (hexagon)  the precision of the slope angle of the heliostat is the major factor  the heliostat of 1002  for the 1MWe solar tower power plant in Beijing are measured and connected successfully.  which influences the efficiency of the system  consisting of 55 mirror facets of 1.8182 m2  consequently  this angle should be tested accurately. In this paper  the methods based on laser deflectometry are proposed to measure the shape error of the mirror facet and the connected error of the facets
