  2. Amdahl's law - Wikipedia

    en.wikipedia.org/wiki/Amdahl's_law

    In computer architecture, Amdahl's law (or Amdahl's argument [1]) is a formula that shows how much faster a task can be completed when you add more resources to the system. The law can be stated as: "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is ...

    en.wikipedia.org/wiki/1:18_scale

    1:18 scale is a traditional scale (ratio) for models and miniatures, in which 18 units (such as inches or centimeters) on the original is represented by one unit on the model. Depending on application, the scale is also called two third inch scale since 1 foot is represented by 2/3 of an inch.

    For dollhouse applications, 1:48 is commonly known as quarter scale (as it is one-quarter of the 1:12 "standard" dollhouse scale). Mainly military aircraft, but in 2005 Tamiya launched a new series of armored fighting vehicle (AFV) models in this scale. It is the American O scale. Architectural model scale corresponding to widely used ...

  5. Single-precision floating-point format - Wikipedia

    en.wikipedia.org/wiki/Single-precision_floating...

    By default, 1/3 rounds up, instead of down like double precision, because of the even number of bits in the significand. The bits of 1/3 beyond the rounding point are 1010... which is more than 1/2 of a unit in the last place. Encodings of qNaN and sNaN are not specified in IEEE 754 and implemented differently on different processors.

  6. Dirac delta function - Wikipedia

    en.wikipedia.org/wiki/Dirac_delta_function

    It is called the delta function because it is a continuous analogue of the Kronecker delta function, which is usually defined on a discrete domain and takes values 0 and 1. The mathematical rigor of the delta function was disputed until Laurent Schwartz developed the theory of distributions, where it is defined as a linear form acting on functions.

    A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...
