  2. Root mean square - Wikipedia

    en.wikipedia.org/wiki/Root_mean_square

    The RMS over all time of a periodic function is equal to the RMS of one period of the function. The RMS value of a continuous function or signal can be approximated by taking the RMS of a sample consisting of equally spaced observations. Additionally, the RMS value of various waveforms can also be determined without calculus, as shown by ...

  3. Root mean square deviation - Wikipedia

    en.wikipedia.org/wiki/Root_mean_square_deviation

    In fluid dynamics, normalized root mean square deviation (NRMSD), coefficient of variation (CV), and percent RMS are used to quantify the uniformity of flow behavior such as velocity profile, temperature distribution, or gas species concentration. The value is compared to industry standards to optimize the design of flow and thermal equipment ...

  4. True RMS converter - Wikipedia

    en.wikipedia.org/wiki/True_RMS_converter

    The RMS value of an alternating current is also known as its heating value, as it is a voltage which is equivalent to the direct current value that would be required to get the same heating effect. For example, if 120 V AC RMS is applied to a resistive heating element it would heat up by exactly the same amount as if 120 V DC were applied.

  5. Random vibration - Wikipedia

    en.wikipedia.org/wiki/Random_vibration

    The root mean square acceleration (G rms) is the square root of the area under the ASD curve in the frequency domain. The G rms value is typically used to express the overall energy of a particular random vibration event and is a statistical value used in mechanical engineering for structural design and analysis purposes.

  6. Form factor (electronics) - Wikipedia

    en.wikipedia.org/wiki/Form_factor_(electronics)

    The squaring in RMS and the absolute value in ARV mean that both the values and the form factor are independent of the wave function's sign (and thus, the electrical signal's direction) at any point. For this reason, the form factor is the same for a direction-changing wave with a regular average of 0 and its fully rectified version.

  7. Alternating current - Wikipedia

    en.wikipedia.org/wiki/Alternating_current

    A sine wave, over one cycle (360°). The dashed line represents the root mean square (RMS) value at (about 0.707). Below an AC waveform (with no DC component) is assumed. The RMS voltage is the square root of the mean over one cycle of the square of the instantaneous voltage.

    Price on eBay: $8,500 Porcelain dolls don’t have to be more than 2 feet tall to be worth a lot of money. This little lady stands only 15 1/2 inches tall, but her ornate details and impressive ...

  9. Root mean square deviation of atomic positions - Wikipedia

    en.wikipedia.org/wiki/Root_mean_square_deviation...

    Typically RMSD is used as a quantitative measure of similarity between two or more protein structures. For example, the CASP protein structure prediction competition uses RMSD as one of its assessments of how well a submitted structure matches the known, target structure. Thus the lower RMSD, the better the model is in comparison to the target ...
