  2. Computation of cyclic redundancy checks - Wikipedia

    en.wikipedia.org/wiki/Computation_of_cyclic...

    A more hardware-efficient technique which has been used for high-speed networking since c. 2000 is state-space transformation. The inner loop of a r {\displaystyle r} -bit-at-a-time CRC engine is to repeatedly update the intermediate remainder y {\displaystyle y} to reflect an r {\displaystyle r} -bit portion of the message y i {\displaystyle y ...

  3. Cyclic redundancy check - Wikipedia

    en.wikipedia.org/wiki/Cyclic_redundancy_check

    In this case, the coefficients are 1, 0, 1 and 1. The result of the calculation is 3 bits long, which is why it is called a 3-bit CRC. However, you need 4 bits to explicitly state the polynomial. Start with the message to be encoded: 11010011101100 This is first padded with zeros corresponding to the bit length n of the CRC.

  4. Heat capacities of the elements (data page) - Wikipedia

    All values refer to 25 °C and to the thermodynamically stable standard state at that temperature unless noted. Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)". Lange indirectly defines the values to be standard atmosphere of "1 atm (101325 Pa)", although citing the same NBS and JANAF sources among others.

  5. Charge carrier density - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier_density

    To calculate this number for electrons, we start with the idea that the total density of conduction-band electrons, , is just adding up the conduction electron density across the different energies in the band, from the bottom of the band to the top of the band .

  6. Vickers hardness test - Wikipedia

    en.wikipedia.org/wiki/Vickers_hardness_test

    The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the ...

  7. Elastic properties of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Elastic_properties_of_the...

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

  8. Miller index - Wikipedia

    en.wikipedia.org/wiki/Miller_index

    This construction corresponds precisely to the standard "cut-and-project" method of defining a quasicrystal, using a plane with irrational-ratio Miller indices. (Although many quasicrystals, such as the Penrose tiling , are formed by "cuts" of periodic lattices in more than three dimensions, involving the intersection of more than one such ...

  9. Bennett acceptance ratio - Wikipedia

    en.wikipedia.org/wiki/Bennett_acceptance_ratio

    The Bennett acceptance ratio method (BAR) is an algorithm for estimating the difference in free energy between two systems (usually the systems will be simulated on the computer). It was suggested by Charles H. Bennett in 1976.
