Miroist - An arcsecond among pioneers
How Small is an Arcsecond?In the motion control industry, accuracy is the difference between target position and actual position. For rotary encoders, we measure accuracy in degrees, arcminutes or arcseconds. 1 degree = 1/360th of a circle - used with low accuracy encoders arcminute = 1...

IN the course of some investigations on arc discharges with oxide-coated cathodes in rare gases, a new dark sheath with a sharp boundary was seen between the well-known Langmuir double space-charge sheath on the cathode and the light of the arc plasma. Fig. 1 shows diagrammatically (a) ...
Albedo is a measure of the reflectivity of a surface. Dark surfaces absorb far more energy than white surfaces. Once the Arctic Ocean is devoid of it’s highly reflective, white, icy surface, far more solar energy will be absorbed by both the atmosphere over the ocean and the ocean itself...
Measure the length of the chord and the length of the bisecting line segment from the chord to the top of the arc. Step 7 Enter the values into the formula (h/2) + (w^2/8h), where h is the arc height and w is the length of the chord. The result will be the radius. ...
Two independent anode arrays, each consisting of 30 100-μm-diameter wires spaced on 200-μm centers were used to measure coordinates of the MCP output. One array is orthogonally mounted above the other, and their relative potentials are adjusted so that about half the MCP output charge is ...
Also, the participants were administered the Dutch version of the revised 25-item Disgust Scale (DS-R-NL; Haidt et al.,1994; modified by Olatunji et al.,2007, Dutch version: M. van Overveld) to measure individual differences in disgust sensitivity. Cronbach’s alpha of the scale in the ...
The basic reproduction number $${\mathscr {R}}_0$$ is a fundamental concept in mathematical epidemiology and infectious disease modeling. Loosely speaking,
To solve this word problem, we have to relate the sum of the measures of each of the 8 angles of the octagon, with the total measure of its angles. For this, we need to know what is the total of all the angles of an octagon....
