[The ancient literature source and flow of the point to point penetration acupuncture method].
Zhen ci yan jiu = Acupuncture research, 2022It has been the consensus of the academic community that the doctor DOU Han-qing in Jin-Yuan Dynasty was the pioneer of point to point penetration acupuncture method.The contents of several texts in Yuan-Ming-Qing Dynasties were combed on the basis of Dou Taishi Zhenjing(《》).The paradigm,the acupoints,basic elements and the characteristics of the main ...

A novel photometric stereo method with nonisotropic point light sources
2016 23rd International Conference on Pattern Recognition (ICPR), 2016This paper presents a photometric stereo method with nonisotropic point light sources. Subject to the non-uniform lighting conditions produced by the nonisotropic point sources, each incident light ray should be precisely determined so as to realize an accurate calculation of surface normal. In the proposed method, radiance model of the light source is

2. Point-source/point-receiver methods
2001Publisher Summary This chapter explains a suite of techniques that elicit information on the elastic properties of solids using point-like excitation and detection of ultrasound. These point-source/point-receiver (PS/PR) techniques have shown great promise in several materials' inspection and characterization applications.

An efficient method of generating random permeability fields by the source point method
Mathematical Geology, 1993Aquifer properties, for example permeability and porosity, vary in space and may be characterized by their distributions. The property distribution is not totally random but shows some correlation structure. Because most of the values are not known, some rational method is required to generate credible aquifer distribution properties for inclusion in ...

SLODAR method. Part 2: The use of point sources
Atmospheric and Oceanic Optics, 2010The SLOpes Detection And Ranging (SLODAR) method is supplemented with the theory of the measurement of the positions of aberration layers for the case of the use of point reference sources having converging/diverging wavefronts. We determine the dependence of the shift in the correlation peak on the distance to the measured aberration layer, the ...

A Point-Source Method for Sampling Soil Atmospheres
Transactions of the ASAE, 1980ABSTRACT A point-source soil atmospheric sampler was designed and field tested. Equilibration periods of 1 h after placement were enough to achieve representative in situ samples from an agricultural silt loam soil. Vectorial variability of C02 in the horizontal direction was occa-sionally significant, whereas variability of C02 was con-sistently ...

A computer method for calculation of the point source response of a focusing collimator
Physics in Medicine & Biology, 1970A digital computer is used with a ray tracing technique to calculate the response of a multihole focusing collimator to a point source of radiation placed anywhere in the object space. The analysis is applicable to a focusing collimator with circular holes and includes both the geometrical contribution to the response and the effects arising from both ...
