partial geometry
Examples
- Abstract : the end basket with a form of double layered conical weave net is simplified into a model of continuous conical shell - beam combined structure and in accordance with the test results of experimental modal analysis . a part of geometrical and material parameters of the conical shell in the model are identified to get an equivalent mechanical model which has the same dynamic characteristics as that of the prototype structure . by simulation and experiment , the effectiveness of the method offered is fully verified
文摘:将大型汽轮发电机定子端部的双层圆锥型编织网壳简化为连续锥壳-梁组合结构.根据实际结构的试验模态分析所得到的模态参数识别模型中锥壳的部分几何、弹性参数,获得了与定端绕组实际结构具有相同动特性的当量力学模型.对实际机组的计算和实验结果证明了本文中的方法是可行的 - ( 2 ) based on the concept of watermarking as communication with side information which was proposed by cox , we proposed a watermarking algorithm , by using the information extracted from cover image at the embedder , this watermarking strategy has achieved partial resistance to geometrical transformations and some common image processing operations
