Minories is a 'deceptively simple' [1] design for a model railway layout, designed by C. J. Freezer. The design was first published in Railway Modeller in 1957 and it became a regular of Peco's many collected plans books afterwards. [2] It is notable as an influential design, more than as a single instance of the model.
As shown in the phase diagram, at very low temperatures the concentrated phase is essentially pure 3 He, while the dilute phase contains about 6.6% 3 He and 93.4% 4 He. The working fluid is 3 He, which is circulated by vacuum pumps at room temperature. The 3 He enters the cryostat at a pressure of a few hundred millibar.
In photographic optics, the Zeiss formula is a supposed formula for computing a circle of confusion (CoC) criterion for depth of field (DoF) calculations. The formula is c = d / 1730 {\displaystyle c=d/1730} , where d {\displaystyle d} is the diagonal measure of a camera format, film, sensor, or print, and c {\displaystyle c} the maximum ...
Cyril John Freezer (27 June 1924 – 19 May 2009) was an English railway modeller, writer, and magazine editor. He edited Railway Modeller from 1950 to 1978, and Model Railways from 1978 until 1983.
Information criterion may refer to: Information criterion (statistics) , a method to select a model in statistics Information criteria (information technology) , a component of an information technology framework which describes the intent of the objectives
The Nyquist plot for () = + + with s = jω.. In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [] at Siemens in 1930 [1] [2] [3] and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, [4] is a graphical technique ...
A single unconstrained body soaring in 3-space has 6 degrees of freedom: 3 translational (say, x,y,z); and 3 rotational (say, roll, pitch, yaw). So a system of n {\displaystyle n} unconnected rigid bodies moving in space (a flock of n {\displaystyle n} soaring seagulls) has 6 n {\displaystyle 6n} degrees of freedom measured relative to a fixed ...
