  2. Paschen's law - Wikipedia

    en.wikipedia.org/wiki/Paschen's_law

    Paschen curves obtained for helium, neon, argon, hydrogen and nitrogen, using the expression for the breakdown voltage as a function of the parameters A,B that interpolate the first Townsend coefficient.

  3. Neon-sign transformer - Wikipedia

    en.wikipedia.org/wiki/Neon-sign_transformer

    An iron cored neon-sign transformer, with a 9-volt battery for scale. A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert mains voltage in the range 120-347 V up to high voltages, in the range of 2 to 15 kV. These transformers supply between 18-30 mA; 60 mA on special order. [1]

  4. Ordered dithering - Wikipedia

    The algorithm reduces the number of colors by applying a threshold map M to the pixels displayed, causing some pixels to change color, depending on the distance of the original color from the available color entries in the reduced palette.

    en.wikipedia.org/wiki/Nixie_tube

    The stacked digit arrangement in a Nixie tube is visible in this (stripped) ZM1210. The most common form of Nixie tube has ten cathodes in the shapes of the numerals 0 to 9 (and occasionally a decimal point or two), but there are also types that show various letters, signs and symbols.

    Therefore, it is very effective for a wide motion search of many different blocks. SAD is also easily parallelizable since it analyzes each pixel separately, making it easily implementable with such instructions as ARM NEON or x86 SSE2. For example, SSE has packed sum of absolute differences instruction (PSADBW) specifically for this purpose.

    en.wikipedia.org/wiki/Effective_nuclear_charge

    The effective atomic number Z eff, (sometimes referred to as the effective nuclear charge) of an electron in a multi-electron atom is the number of protons that this electron effectively 'sees' due to screening by inner-shell electrons.
