magnification factor

Abbreviation: MF
A quantitative expression of the degree of enlargement of an image in which the image size is divided by object size. In radiography, it is the ratio of the source-to-image-receptor distance to the source-to-object distance.

where 1/[[gamma].sup.7] is the magnification factor, [[pi].sub.G] is the growth rate of TFP based on gross output, [[pi].sub.VA] is the growth rate of TFP based on value added, [[GAMMA].sub.X.sup.8] is the growth factor of primary inputs, Tm is the growth factor of intermediate inputs, 5[degrees]m is the nominal share of intermediate inputs in total input use, and (1 - [S.sup.0.sub.M]) is the share of primary inputs in total input use.
In order to magnify smaller subwavelength information, the magnification factor A should be much larger than 1 (e.g., A = 10).
where M is a constant magnification factor associated with the experimental setup, which is largely dependent on the digital camera; [u.sup.D] and [v.sup.D] are the pixel-based displacements from the image analysis.
The magnification factor for the transmitted and scattered fluxes is set to the same value since both fluxes enter the IS through the same entrance aperture.
Other features of the camera include a high-quality zoom lens with a magnification factor of up to 2.3, auto focus, video sequence capability, multiple exposure function, collage function, manual exposure and white compensation, four sensitivity settings, USB interface, and a 2" TFT color monitor.
This is where GFOV and display field of view (DFOV) are integrated, creating an image scale magnification factor. As illustrated in Figure 1, if the GFOV angle is less than the corresponding DFOV angle, the viewport image will appear magnified on the physical display because of the requirement for the image to fill a larger subtended angle in real space versus virtual space.
Of course, the size of the exit pupil and field of view differ due to the magnification factor, but those are the only differences.
Emmert said he hadn't noticed the change in aspect ratio, probably because it hasn't much changed the magnification factor from a CCD array that is smaller than a 35mm frame, boosting effective focal length by a factor of 1.6.
Magnification Factor = Source Image Distance/Source Object Distance
The discussion of surveys and their uncertainty emphasizes the magnification factor, the size of the entire population divided by the total size of samples.
