The physical properties of the calcium-stearate monomolecular layer have been examined using an automatic torsion balance. These layers were obtained by adsorption of Ca 2+ ions from 10 −4 M CaCl 2 onto the stearic-acid monomolecular layer. The Int

Carbon-14 in the form of [ 14 C]tartaric acid solution has been standardized by means of 4πβ liquid-scintillation efficiency tracing using the NBS [ 3 H]water standard. The method of computing the detector efficiency for a two-phototube counting sy

A fundamental group in computer vision is the recovery of three-dimensional shape from image data. While this problem is in general underconstrained, the authors show that it can be simplified in the case where the objects being viewed are generalize

At the summer school held in Herceg Novi in 1972, a paper was given on the then contemporary needs in the field of radionuclide metrology. In the intervening years many of the measurements needs have been met and, moreover, the interest in nuclear po

The National Bureau of Standards activity standards for tritiated water, SRM 4926 and SRM 4927, have been recalibrated by the method of internal gas-proportional counting, and a new series of standards has been prepared. These standards are used in m
