  1. Q meter

    A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring device, though it is still in use among radio amateurs. It was developed at Boonton Radio Corporation in Boonton, New Jersey in 1934 by William D. Loughlin. A Q meter measures Q, the quality factor of a circuit, which expresses how much energy is dissipated per cycle in a non-ideal reactive circuit: This expression applies to an RF and microwave filter, bandpass LC filter, or any resonator. It also can be applied to an inductor or capacitor at a chosen frequency. For inductors Where is the reactance of the inductor, is the inductance, is the angular frequency and is the resistance of the inductor. The resistance represents the loss in the inductor, mainly due to the resistance of the wire. For LC band pass circuits and filters: Where is the resonant frequency and is the filter bandwidth. In a band pass filter using an LC resonant circuit, when the loss of the inductor increases, its Q is reduced, and so the bandwidth of the filter is increased. In a coaxial cavity filter, there are no inductors and capacitors, but the cavity has an equivalent LC model with losses and the Q factor can be applied as well.

  1. Kent Moore:

    What we found is from year to year, the ice thickness can change by about 1 meter [3 feet].

  2. Steve Prefontaine:

    A lot of people run a race to see who is fastest. I run to see who has the most guts, who can punish himself into exhausting pace, and then at the end, punish himself even more. Nobody is going to win a 5,000 meter race after running an easy 2 miles. Not with me. If I lose forcing the pace all the way, well, at least I can live with myself.

  3. Yoko Masuzawa:

    It was built so close, less than a meter away in some places.

  4. LaDawnna Burnett, (1975-), Letters on Ethics:

    Shame is that intrinsic meter of our own heart to tell us that we have failed to follow our own moral compass.

  5. Adam Aja:

    It is uncertain what constrained our cemetery, forcing such an overuse of each square meter of soil, it was never clear whether the cemetery was circumscribed so that all burials were forced into a particular plot or whether the burials were clustered around some feature in the landscape. In either case, if this measured density was extrapolated across just the excavated areas, the number of burials would top 1200 persons.
