The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.
Fast Walsh–Hadamard transform. In computational mathematics, the Hadamard ordered fast Walsh–Hadamard transform (FWHTh) is an efficient algorithm to compute the Walsh–Hadamard transform (WHT). A naive implementation of the WHT of order would have a computational complexity of O ( ). The FWHT h requires only additions or subtractions.
The Thiele Modulus was developed to describe the relationship between diffusion and reaction rates in porous catalyst pellets with no mass transfer limitations. This value is generally used to measure the effectiveness factor of pellets. The Thiele modulus is represented by different symbols in different texts, but is defined in Hill [2] as hT.
Construction of by setting q to 1 (note some letters are different than used throughout the rest of the article, notably the articles' DC is BF on the image). The above method from Squaring a rectangle also allows for the construction of square roots (see constructible number) by starting with a rectangle whose side q is 1, since then the first version of the formula becomes =, showing ...
Example clusterings for a dataset with the kMeans (left) and Mean shift (right) algorithms. The calculated Adjusted Rand index for these two clusterings is . The Rand index [1] or Rand measure (named after William M. Rand) in statistics, and in particular in data clustering, is a measure of the similarity between two data clusterings.
In engineering and stability theory, a square matrix is called a Hurwitz matrix if every eigenvalue of has strictly negative real part, that is, for each eigenvalue . is also called a stable matrix, because then the differential equation. is asymptotically stable, that is, as. If is a (matrix-valued) transfer function, then is called Hurwitz if ...
In most modern typefaces, the height of the 0 character is the same as the other digits. However, in typefaces with text figures, the character is often shorter . A comparison of the letter O and the number 0. Traditionally, many print typefaces made the capital letter O more rounded than the narrower, elliptical digit 0. [1]
