  2. Go First Dice - Wikipedia

    en.wikipedia.org/wiki/Go_First_Dice

    Go First Dice are a set of dice in which, when rolled together, each die has an equal chance of showing the highest number, the second highest number, and so on. [1] [2] The dice are intended for fairly deciding the order of play in, for example, a board game. The number on each side is unique among the set, so that no ties can be formed.

  3. Rolling (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Rolling_(metalworking)

    In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

  4. Rolling hash - Wikipedia

    en.wikipedia.org/wiki/Rolling_hash

    A rolling hash (also known as recursive hashing or rolling checksum) is a hash function where the input is hashed in a window that moves through the input.. A few hash functions allow a rolling hash to be computed very quickly—the new hash value is rapidly calculated given only the old hash value, the old value removed from the window, and the new value added to the window—similar to the ...

  5. Exponential smoothing - Wikipedia

    en.wikipedia.org/wiki/Exponential_smoothing

    Exponential smoothing or exponential moving average (EMA) is a rule of thumb technique for smoothing time series data using the exponential window function.Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time.

  6. Roll bonding - Wikipedia

    en.wikipedia.org/wiki/Roll_bonding

    Roll bonding is a solid state, cold welding process, obtained through flat rolling of sheet metals. In roll bonding, two or more layers of different metals are passed through a pair of flat rollers under sufficient pressure to bond the layers. The pressure is high enough to deform the metals and reduce the combined thickness of the clad material.

  7. Multiple buffering - Wikipedia

    en.wikipedia.org/wiki/Multiple_buffering

    In computer science, multiple buffering is the use of more than one buffer to hold a block of data, so that a "reader" will see a complete (though perhaps old) version of the data instead of a partially updated version of the data being created by a "writer". It is very commonly used for computer display images.

  8. Roll forming - Wikipedia

    en.wikipedia.org/wiki/Roll_forming

    Roll forming is, among the manufacturing processes, one of the simplest. It typically begins with a large coil of sheet metal, between 1 inch (2.5 cm) and 20 inches (51 cm) in width, and 0.004 inches (0.10 mm) and 0.125 inches (3.2 mm) thick, supported on an uncoiler.

    In a fixed effects model, is assumed to vary non-stochastically over or making the fixed effects model analogous to a dummy variable model in one dimension. In a random effects model, ε i t {\displaystyle \varepsilon _{it}} is assumed to vary stochastically over i {\displaystyle i} or t {\displaystyle t} requiring special treatment of the ...
