and measured their strip densities by using the proposed method to demonstrate its viability assessment.
We have recently developed very precise carbon-interspaced antiscatter grids having a wide range of grid strip densities (i.e., 85 234 lines/in).
In this work, we proposed a pragmatic method to measure actual grid strip densities over the Nyquist sampling rate based on the moiré pattern analysis.
We prepared several samples of the carbon-interspaced grids having nominal grid strip densities of 85, 103, 130, 150, 178, 203, 215, and 234 lines/in.
However, because grid strips of the recently developed grids are mostly invisible through X-ray nondestructive testing due to their high strip densities, quality assurance in the manufacturing has not yet satisfactorily made.
The differences between the nominal and the measured grid strip densities were less than about 1.8%, indicating the proposed method is useful for the quality assurance in grid manufacturing.
ρ S, C S and k S are the strip's density, specific heat capacity and heat conductivity respectively.
Faraday's law was used to demonstrate that galvanostatic dissolution of hot-dip zinc coating at 12.7 mA cm− 2 proceeds by electrochemical mechanism without chemical dissolution; on the contrary, the occurrence of this second process was found at lower stripping current density.
In Gaza about 1.5m people now crowd into 360 square kilometres (140 square miles), making the strip's population density about two-thirds Hong Kong's.
The components of LUGI include segregated land use, development planning consistency, urban density, strip and leapfrog development, that have been tested at Kuala Lumpur Metropolitan purposely to examine the urban sprawl phenomenon at the level of alpha cities.
