  4. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.

  5. Rotordynamics - Wikipedia

    en.wikipedia.org/wiki/Rotordynamics

    Rotordynamics (or rotor dynamics) is a specialized branch of applied mechanics concerned with the behavior and diagnosis of rotating structures. It is commonly used to analyze the behavior of structures ranging from jet engines and steam turbines to auto engines and computer disk storage.

  6. Transmissibility (vibration) - Wikipedia

    en.wikipedia.org/wiki/Transmissibility_(vibration)

    Transmissibility is the ratio of output to input.. It is defined as the ratio of the force transmitted to the force applied. Transmitted force implies the one which is being transmitted to the foundation or to the body of a particular system.

  7. Vibration-powered generator - Wikipedia

    en.wikipedia.org/wiki/Vibration-powered_generator

    Generally, the coil is made using a diamagnetic material as these materials have weaker interactions with the magnet that would dampen the vibration. The main advantage of this type of generator is that it is able to produce more power than the piezoelectric generators. [1] Electromagnetic based vibration-powered generators have been ...

  9. Chirp compression - Wikipedia

    en.wikipedia.org/wiki/Chirp_compression

    The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.
