The National 2.5 in Gauge Association continues to support live steam passenger hauling in 2.5-inch gauge using MES tracks. They use a "scale" appropriate to the original prototype modelling both standard and narrow gauge locomotives to run on 2.5-inch track. -1:16: 3 + 1 ⁄ 2 in (89 mm) A worldwide garden railroad scale.
In contrast to conventional side-scan sonar (SSS), SAS processing provides range-independent along-track resolution. At maximum range the resolution can be magnitudes better than that of side-scan sonars. [2] A 2013 technology review [3] with examples and future trends is also available.
SAS Enterprise Guide is SAS's point-and-click interface. It generates code to manipulate data or perform analysis without the use of the SAS programming language. [10] The SAS software suite has more than 200 add-on packages, sometimes called components [11] [12] [13] Some of these SAS components, i.e. add on packages to Base SAS include: [3] [14]
The most common criterion for promoting a tentative track to a confirmed track is the "M-of-N rule", which states that during the last N radar updates, at least M plots must have been associated with the tentative track - with M=3 and N=5 being typical values.
4 ft 8 in gauge railways are railways with a track gauge of 4 ft 8 in / 1,422 mm. This gauge is 1 ⁄ 2 inch (13 mm) less than 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ) standard gauge The first such railways were the Killingworth Railway [ 1 ] [ 2 ] and the Stockton and Darlington Railway [ note 1 ]
9-track tape is a format for magnetic-tape data storage, introduced with the IBM System/360 in 1964. The 1 ⁄ 2 inch (12.7 mm) wide magnetic tape media and reels have the same size as the earlier IBM 7-track format it replaced, but the new format has eight data tracks and one parity track for a total of nine

The instrumentation consisted of one 2.5-arc-minutes and one 4.5-arc-minutes Full width at half maximum (FWHM) modulation collimator, as well as proportional counters sensitive over the energy range from 1.5 to 10-keV. The effective area of each collimator was about 225 cm 2. The aspect system provided information on the orientation of the ...
