| 1 | CAD Model-Based Intelligent Inspection Planning for Coordinate Measuring Machines显示文摘As the market competition among enterprises grows intensively and the demand for high quality products increases rapidly, product quality inspection and control has become one of the most important issues of manufacturing, and improving the efficiency and accuracy of inspection is also one of problems which enterprises must solve. It is particularly important to establish rational inspection planning for parts before inspecting product quality correctly. The traditional inspection methods have been difficult to satisfy the requirements on the speed and accuracy of modern manufacturing, so CAD-based computer-aided inspection planning (CAIP) system with the coordinate measuring machines (CMM) came into being. In this paper, an algorithm for adaptive sampling and collision-free inspection path generation is proposed, aiming at the CAD model-based inspection planning for coordinate measuring machines (CMM). Firstly, using the method of step adaptive subdivision and iteration , the sampling points for the specified number with even distribution will be generated automatically. Then, it generates the initial path by planning the inspection sequence of measurement points according to the values of each point's weight sum of parameters, and detects collision by constructing section lines between the probe swept-volume surfaces and the part surfaces, with axis-aligned bounding box (AABB) filtering to improve the detection efficiency. For collided path segments, it implements collision avoidance firstly aiming at the possible outer-circle features, and then at other collisions, for which the obstacle-avoiding movements are planned with the heuristic rules, and combined with a designed expanded AABB to set the obstacle-avoiding points. The computer experimental results show that the presented algorithm can plan sampling points' locations with strong adaptability for different complexity of general surfaces, and generate efficient optimum path in a short time and avoid collision effectively. | DONG Yude LIU Daxin ZHAO Han WANG Wanlong WU Juan | 2011 | Chinese Journal of Mechanical Engineering2011,24,4: | 8 |
| 2 | Three-dimensional conformal intensity-modulated radiation therapy of left femur foci does not damage the sciatic nerve显示文摘During radiotherapy to kill femoral hydatid tapeworms,the sciatic nerve surrounding the focus can be easily damaged by the treatment.Thus,it is very important to evaluate the effects of radiotherapy on the surrounding nervous tissue.In the present study,we used three-dimensional,conformal,intensity-modulated radiation therapy to treat bilateral femoral hydatid disease in Meriones meridiani.The focus of the hydatid disease on the left femur was subjected to radiotherapy(40 Gy) for 14 days,and the right femur received sham irradiation.Hematoxylin-eosin staining,electron microscopy,and terminal deoxynucleotidyl transferase-d UTP nick end labeling assays on the left femurs showed that the left sciatic nerve cell structure was normal,with no obvious apoptosis after radiation.Trypan blue staining demonstrated that the overall protoscolex structure in bone parasitized with Echinococcus granulosus disappeared in the left femur of the animals after treatment.The mortality of the protoscolex was higher in the left side than in the right side.The succinate dehydrogenase activity in the protoscolex in bone parasitized with Echinococcus granulosus was lower in the left femur than in the right femur.These results suggest that three-dimensional conformal intensity-modulated radiation therapy achieves good therapeutic effects on the secondary bone in hydatid disease in Meriones meridiani without damaging the morphology or function of the sciatic nerve. | Wanlong Xu Xibin Zhao Qing Wang Jungang Sun Jiangbo Xu Wenzheng Zhou Hao Wang Shigui Yan Hong Yuan | 2014 | Neural Regeneration Research2014,9,20: | 6 |
| 3 | Interactive information disclosure and non-penalty regulatory review risk显示文摘Using monthly data from the Shenzhen Stock Exchange's‘Hudongyi’platform and comment letters from December 2014 to December 2018,this study investigates the influence of interactive information disclosure on non-penalty regulatory review risk.The findings reveal that the richness and activeness of interactive information disclosure are positively associated with regulatory review risk.Moreover,the non-penalty regulatory review is effective as it significantly reduces the probability of receiving a comment letter in the subsequent three periods.The timeliness of interactive information disclosure is negatively associated with regulatory review risks.Additionally,we find that newspaper media coverage partially mediates the relationship between interactive information disclosure and regulatory review risk.For companies with low levels of internal governance,in low-competitive industries,and state-owned companies,the positive relationship between the number of investor questions and regulatory review risk is strengthened.These findings enrich the literature on the determinants of regulatory review risk and the economic consequences of interactive information disclosure in emerging markets. | Meng Wang Yongjie Zhang Yizhe Dong Gaofeng Zou Wanlong Zhao | 2023 | Journal of Management Science and Engineering2023,8,1: | 0 |
