Roof prism. A roof pentaprism used in Single-lens reflex cameras; the lower right face is the roof ( dach ). A roof prism, also called a Dachkanten prism or Dach prism (from German: Dachkante, lit. "roof edge"), is a reflective prism containing a section where two faces meet at a 90° angle, resembling the roof of a building and thus the name.
The Šidák correction is derived by assuming that the individual tests are independent. Let the significance threshold for each test be α 1 {\displaystyle \alpha _{1}} ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant).
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
The Mamiya 645 Pro was manufactured from 1993 to 1998. It added a self-timer and a smoother styling. The standard lens was the 80mm f/2.8 N or the 80mm f/1.9 N. [1] [8] The Mamiya 645 Pro-TL was manufactured from 1997 to 2006 and is functionally similar to the 645 Pro but adds through-the-lens flash metering.
An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...
The simple Bonferroni correction rejects only null hypotheses with p-value less than or equal to , in order to ensure that the FWER, i.e., the risk of rejecting one or more true null hypotheses (i.e., of committing one or more type I errors) is at most . The cost of this protection against type I errors is an increased risk of failing to reject ...
Printers use the term "gang run" or "gang" to describe the practice of placing many print projects on the same sheet or piggybacking a project on a vacant, unused portion of a print sheet. Sheet-fed presses are generally "full sheet" (28" x 40"), "half sheet" (28" x 19"), or "quarter sheet" (13" x 19"). In offset printing, the first sheet costs ...
Correction paper. A sheet of correction paper in a typewriter. Correction paper, or correction film, its plastic based equivalent, is a tab of plastic with one side coated with white correction material. It is used to correct typing errors made when using a typewriter. When inserted between the paper and the ribbon, the impression of the ...
