2. Noise (electronics) - Wikipedia

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

   Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.

3. Triboelectric effect - Wikipedia

   en.wikipedia.org/wiki/Triboelectric_effect

   Triboelectric noise within medical cable assemblies and lead wires is generated when the conductors, insulation, and fillers rub against each other as the cables are flexed during movement. Keeping triboelectric noise at acceptable levels requires careful material selection, design, and processing. [ 150 ]

4. Washing machine - Wikipedia

   en.wikipedia.org/wiki/Washing_machine

   Around 2015 and 2017, some manufacturers [97] [98] [99] (namely Samsung and LG Electronics) offered washers and dryers that either have a top-loading washer and dryer built on top of a front-loading washer and dryer respectively (in Samsung washers and dryers) or offer users an optional top-loading washer that can be installed under a washer or ...

5. Burst noise - Wikipedia

   en.wikipedia.org/wiki/Burst_noise

   Burst noise is a type of electronic noise that occurs in semiconductors and ultra-thin gate oxide films. [1] It is also called random telegraph noise ( RTN ), popcorn noise , impulse noise , bi-stable noise , or random telegraph signal ( RTS ) noise.

6. Lagrange, Euler, and Kovalevskaya tops - Wikipedia

   en.wikipedia.org/wiki/Lagrange,_Euler,_and...

   In classical mechanics, the rotation of a rigid body such as a spinning top under the influence of gravity is not, in general, an integrable problem.There are however three famous cases that are integrable, the Euler, the Lagrange, and the Kovalevskaya top, which are in fact the only integrable cases when the system is subject to holonomic constraints.

7. Spinning wheel - Wikipedia

   en.wikipedia.org/wiki/Spinning_wheel

   A purple and black tabletop electric spinning wheel, or espinner. An electric motor in the base drives the flyer. An electric spinning wheels, or e-spinner, is powered by an electric motor rather than via a treadle. Some require mains power while others may be powered by a low-voltage source, such as a rechargeable battery.
