Passport examination by a confocal-type laser profile microscope

The author proposes a nondestructive and highly precise method of measuring the thickness of a film pasted on a passport using a confocal-type laser profile microscope. The effectiveness of this method in passport examination is demonstrated. A confocal-type laser profile microscope is used to create profiles of the film surface and film–paper interface; these profiles are used to calculate the film thickness by employing an algorithm developed by the author. The film thicknesses of the passport samples—35 genuine and 80 counterfeit Japanese passports—are measured nondestructively. The intra-sample standard deviation of the film thicknesses of the genuine and counterfeit Japanese passports was of the order of 1 μm The intersample standard deviations of the film thicknesses of passports forged using the same tools and techniques are expected to be of the order of 1 μm. The thickness values of the films on the machine-readable genuine passports ranged between 31.95 μm and 36.95 μm. The likelihood ratio of this method in the authentication of machine-readable Japanese genuine passports is 11.7. Therefore, this method is effective for the authentification of genuine passports. Since the distribution of the film thickness of all forged passports was considerably larger than the accuracy of this method, this method is considered effective also for revealing the relation among the forged passports and acquiring proof of the crime.

2012年中海油发布南海油气对外招标公告的法律问题研究

2012年6月,中海油发布了中国南沙海域部分油气区块对外招标公告。对其合法性,中、越双方持截然不同的立场。中方认为该行为符合中国法律和国际惯例,而越方则声称该行为违背《海洋法公约》和国际惯例,是非法和无效的。从法律角度分析,中海油此次公布的9个招标区块很可能全部位于中越争议海域,且此次的招标行为并不违反《海洋法公约》和国际惯例。此外,中海油此次的招标行为对中国在南海断续线内的权利主张可能产生一定程度的影响。     

利用ImageXpress系统灰度特征区分激光打印复印一体机的打印及复印文件初探

目的探索区分激光打印复印一体机的打印文件及复印文件的方法。方法利用ImageXpress系统对理光MP4000BSP激光打印复印一体机的打印文件和复印文件进行灰度特征值的测量。结果两种文件的灰度平均值的平均值和95%置信区间存有明显的差异,且这种差异较为稳定：打印件的平均值约为50,而复印件约为53;打印件的95%置信区间介于50和51.5之间,而复印件的置信区间介于52.5与54之间。结论本方法通过量化对激光打印复印一体机打印及复印文件进行区分是可行的。     

Identification of group affinity from cross-sectional contours of the human midfacial skeleton using digital morphometrics and 3D laser scanning technology

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research.     

基于锦赤铁路的区域经济战略合作问题研究

区域经济一体化是指一些地理相近的国家或地区间通过加强经济合作,为谋求风险成本和机会成本的最小化和利益的最大化。在国家加快推进东北亚区域经济一体化背景下,以锦赤铁路为依托的区域经济合作,成为东北三省和蒙东加强合作的重要支撑点之一。从"港腹联动"与"蒙煤入海"双向需求为出发点,以锦赤铁路为辽蒙的纽带和桥梁,从战略和系统的角度,多层次构建和优化铁路沿线经济带的区域分工,拓宽合作渠道,以促进辽蒙经济实现可持续发展和区域一体化。
