Trans., 1830, 3, p. 1 ) is fulfilled in all systems which are symmetrical with respect to their diaphragm ( briefly named symmetrical or holosymmetrical objectives ), or which consist of two like, but different-sized, components, placed from the diaphragm in the ratio of their size, and presenting the same curvature to it ( hemisymmetrical objectives ); in these systems tan w ' / tan w

This combined condition is exactly fulfilled by holosymmetrical objectives reproducing with the scale 1, and by hemisymmetrical, if the scale of reproduction be equal to the ratio of the sizes of the two components.

Instead, the ratio of the speed of the wind and that of the cups, the anemometer factor, depends on the dimensions of the cups and arms, and may have a value between two and a little over three.

The ratio of these two is quoted as the amplifier dynamic range.

However, before reaching the transition temperature, the specific heat of the superconductor becomes even higher than that of the normal conductor ( measured immediately above the transition ) and the ratio of these two values is found to be universally given by 2. 5.

For example, water is a compound containing hydrogen and oxygen in the ratio of two to one, with the oxygen atom between the two hydrogen atoms, and an angle of 104. 5 ° between them.

However, the instability in the ratio between the two grew over the course of the 19th century, with the increase both in supply of these metals, particularly silver, and of trade.

Mass-dependent differences in calcium isotope composition conventionally are expressed the ratio of two isotopes ( usually < sup > 44 </ sup > Ca /< sup > 40 </ sup > Ca ) in a sample compared to the same ratio in a standard reference material.

The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.

The simplest Cauchy distribution is called the standard Cauchy distribution is the distribution of a random variable that is the ratio of two independent standard normal random variables.

When U and V are two independent normally distributed random variables with expected value 0 and variance 1, then the ratio U / V has the standard Cauchy distribution.

suggesting the ratio of two infinitesimal quantities.

Comparing the two formulae it can be seen that for a given compression ratio (), the ideal Otto cycle will be more efficient.

The eccentricity of an ellipse, usually denoted by ε or e, is the ratio of the distance between the two foci, to the length of the major axis or e = 2f / 2a = f / a.

The ratio of the spacing of two consecutive frets is ( twelfth root of two ).

Since the intonation of most modern western fretted instruments is equal tempered, the ratio of the distances of two consecutive frets to the bridge is, or approximately 1. 059463.

The ratio between consecutive coefficients now has the form

Also like all Fibonacci integer sequences, the ratio between two consecutive Lucas numbers converges to the golden ratio.

combining 256 consecutive 20-bit samples can increase the signal-to-noise ratio by a factor of 16 ( the square root of the number of samples averaged ), adding 4 bits to the resolution, producing a single sample with 24-bit resolution.

For a time McManaman held the record for most consecutive Premier League appearances as an ever present at Liverpool for four seasons including a club record for most appearances, and at the time of leaving the Premiership had the second highest ratio of Premier League assists per game, with 112 assists in 274 appearances, with a total of 142 assists for the club ; an average of one assist per two and a half games.

In their 1944 paper, Alaoglu and Erdős managed to show that the ratio of two consecutive superabundant numbers was always a prime number, but couldn't quite achieve this for colossally abundant numbers.

Determine the ratio that the amount being allotted is to the sum of the products for all the States.

An example of the overall standards applied is the 20-to-1 ratio established for the determination of that degree of cochannel interference which is regarded as objectionable.

A cylinder's compression ratio is computed by comparing the cylinder's volume, or its displacement, with the total volume of the cylinder and its combustion chamber.

The ratio of the measured antenna temperature change during a drift scan across the moon to the average brightness temperature of the moon over the antenna beam ( assuming that the brightness temperature of the sky is negligible ) was found, by graphical integration of the antenna directivity diagram, to be 0.85.

A well-publicized entrant which has achieved success only recently is the built liquid detergent, with which the major problem today is incorporation of builder and active into a small volume using a sufficiently high builder/active ratio.

It will be seen that where the scope is similar, the Athabascan ratios come out somewhat higher ( as indeed they ought to with a total ratio of 2.8 as against 3.5 or 4: 5 ) except for verbs, where alone the Athabascan ratio is lower.
