Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangle was equivalent to the diameter of the tube's face.

Since radio waves travel at the speed of light, accurate distance measurement requires high-performance electronics.

Since in astronomical applications this measurement cannot be done directly, because that would require travelling to the distant star of interest, the method using spectral lines described here is used instead.

Since the Heisenberg principle limits the precision of any measurement of the combination of an electron's momentum ( related to energy ) and its position, in a crystal effectively the available energy levels form a continuous band of allowed energy levels.

Since the measurement is relative to the horizon, the measuring pointer is a beam of light that reaches to the horizon.

Since reference datums can have different radii and different center points, a specific point on the earth can have substantially different coordinates depending on the datum used to make the measurement.

Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.

Since the number of participating teams has changed considerably over time, any accurate performance measurement must take this variable into account.

Since it is a relative measurement, and not a unit itself, the meters must be referenced to a nominal level.

Since then, advances in optical measurement and fabrication have allowed the RCT design to take over-the Hale telescope turned out to be the last world-leading telescope to have a parabolic primary mirror.

Since there can be only one physical state of B after the interaction which cannot reasonably be considered to depend on the particular measurement we perform on the system A separated from B it may be concluded that the ψ function is not unambiguously coordinated to the physical state.

Since 1900, when Bushy House was selected as the site of NPL, it has developed and maintained the primary national measurement standards.

Since the uncertainty ( and hence measurement noise ) stays constant at 1 / 2 as the amplitude of the oscillation increases, the state behaves more and more like a sinusoidal wave, as shown in Figure 1.

Since the molecular weight of glucose C < sub > 6 </ sub > H < sub > 12 </ sub > O < sub > 6 </ sub > is about 180 g / mol, for the measurement of glucose, the difference between the two scales is a factor of 18, so that 1 mmol / L of glucose is equivalent to 18 mg / dL.

Since we cannot see into the brain, various models and measurement tools have been constructed to obtain emotion and attitude information.

Since the 1990s, various software packages have eased stimulus presentation and the measurement of behavior in the laboratory.

Since the location of the beams is relatively easy to determine, the precision of the measurement depends primarily on how small the setup can be made.

Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangle was equivalent to the diameter of the tube's face.

Since then, the primary has been considered an early measurement of the national attitude toward the candidates for nomination.

Since the 1980s, content analysis has become an increasingly important tool in the measurement of success in public relations ( notably media relations ) programs and the assessment of media profiles.

The overall precision of m depends on the precisions of the measurements of U, I, v and g. Since there are already methods of measuring v and g to very high precision, the uncertainty of the mass measurement is dominated by the measurements for U times I, which is the value measured by the watt balance.

Since the mid-1990s, the topics of market risk and credit risk have been the subject of much debate and research, with the result that financial institutions have made significant progress in the identification, measurement and management of both these forms of risk.

Since the same test is administered twice and every test is parallel with itself, differences between scores on the test and scores on the retest should be due solely to measurement error.

Since the 1970s ultrasound scans have allowed measurement of the size of developing embryos directly and so allow for an estimation of gestation age.

Since the telescope has been adjusted by the angle SES ′, the star's apparent position is hence displaced by the same angle.

Since the maximum aperture of the pencils issuing from O is the angle u subtended by the entrance pupil at this point, the magnitude of the aberration will be determined by the position and diameter of the entrance pupil.

Since they act to hold the tendon further away from the joint, the angle of the tendon is increased and thus the leverage of the muscle is increased.

Since this also results in a prediction for the relative strengths of the fundamental interactions which we observe, in particular the weak mixing angle, Grand Unification ideally reduces the number of independent input parameters, but is also constrained by observations.

Since the phase velocity is lower in the second medium ( v < sub > 2 </ sub > < v < sub > 1 </ sub >), the angle of refraction θ < sub > 2 </ sub > is less than the angle of incidence θ < sub > 1 </ sub >; that is, the ray in the higher-index medium is closer to the normal.

Since the scattering angle is uniquely determined for a given and, the number of particles scattered into an angle between and must be the same as the number of particles with associated impact parameters between and.

Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts.

Since the light scattered from extremely small dust particles is strongly forward scattering, although the zodiacal light actually extends all the way around the sky, it is brightest when observing at a small angle with the sun.

Since this angle varies depending on system loading and generation, it is undesirable for the angle to approach 90 degrees.

Since the refractive index for a given medium changes depending on the wavelength of light, Brewster's angle will also vary with wavelength.

Since this is an electromagnetic wave each electric field vector has a corresponding, but not illustrated, magnetic field vector that is at a right angle to the electric field vector and proportional in magnitude to it.

Since the velocity is lower in the second medium ( v < sub > 2 </ sub > < v < sub > 1 </ sub >), the angle of refraction θ < sub > 2 </ sub > is less than the angle of incidence θ < sub > 1 </ sub >; that is, the ray in the higher-index medium is closer to the normal.

Since the head is facing a different direction, the rotation matrix would be popped off the top of the stack and a different rotation matrix about the y-axis with a different angle would be pushed.

Since its emergence in the English language in the 16th century ( related to the German quer, meaning " across, at right angle, diagonally or transverse "), queer has generally meant " strange ", " unusual ", or " out of alignment ".

Since this intensity depends upon both distance and relative angle to the screen, angle sensors are located in the gun.

Since the reaction wheel is a small fraction of the spacecraft's total mass, easily-measurable changes in its speed provide very precise changes in angle.

Since the planes are fixed, each rotation has only one degree of freedom, its angle.
