The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt".
v. t. e. The Universal Transverse Mercator ( UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
1:48 scale is a scale commonly used in diecast models, plastic models made from kits, and construction toys.It is especially popular with manufacturers of model aircraft and model trains, where it is known as "O scale". 1:48 is also a popular scale among Lego enthusiasts, since it is approximately the scale of the Lego minifigure relative to a six-foot tall human.
The EC 50 relates to the Hill equation, which is a function of the agonist concentration, [A]: where E is the observed response or effect above baseline, and n, the Hill coefficient reflects the slope of the curve. [ 7] The EC 50 represents the point of inflection of the Hill equation, beyond which increases of [A] have less impact on E.
Sheet resistance is the resistance of a square piece of a thin material with contacts made to two opposite sides of the square. [ 1] It is usually a measurement of electrical resistance of thin films that are uniform in thickness. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive paste ...
From Figure 8, the intersection of 1 / β and A OL occurs at f 0 dB = 1 kHz. Notice that the peak in the gain A FB near f 0 dB is almost gone. [note 2] [9] Figure 9 is the phase plot. Using the value of f 0 dB = 1 kHz found above from the magnitude plot of Figure 8, the open-loop phase at f 0 dB is −135°, which is a phase margin of 45 ...
1:22.6. 2. +. 1⁄2 in ( 64 mm) The smallest scale able to pull real passengers. Was one of the first popular live steam gauges, developed in England in the early 1900s. In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot.
The standard mild slope equation, without extra terms for bed slope and bed curvature, provides accurate results for the wave field over bed slopes ranging from 0 to about 1/3. [11] However, some subtle aspects, like the amplitude of reflected waves, can be completely wrong, even for slopes going to zero.
