Rapid automatized naming (RAN) is a task that measures how quickly individuals can name aloud objects, pictures, colors, or symbols (letters or digits). Variations in rapid automatized naming time in children provide a strong predictor of their later ability to read, and is independent from other predictors such as phonological awareness, verbal IQ, and existing reading skills.

The Mersenne Twister is a general-purpose pseudorandom number generator (PRNG) developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士). [1] [2] Its name derives from the choice of a Mersenne prime as its period length. The Mersenne Twister was designed specifically to rectify most of the flaws found in older PRNGs.
Stephen Wolfram used randomness tests on the output of Rule 30 to examine its potential for generating random numbers, [1] though it was shown to have an effective key size far smaller than its actual size [2] and to perform poorly on a chi-squared test. [3] The use of an ill-conceived random number generator can put the validity of an ...
Default generator in R and the Python language starting from version 2.3. Xorshift: 2003 G. Marsaglia [26] It is a very fast sub-type of LFSR generators. Marsaglia also suggested as an improvement the xorwow generator, in which the output of a xorshift generator is added with a Weyl sequence.
The DNA test considers an alphabet of 4 letters C, G, A, T, determined by two designated bits in the sequence of random integers being tested. It considers 10-letter words, so that as in OPSO and OQSO, there are 2 20 possible words, and the mean number of missing words from a string of 2 21 (overlapping) 10-letter words (2 21 + 9 "keystrokes ...
The exact phrase three-letter acronym appeared in the sociology literature in 1975. [1] Three-letter acronyms were used as mnemonics in biological sciences, from 1977 [2] and their practical advantage was promoted by Weber in 1982. [3] They are used in many other fields, but the term TLA is particularly associated with computing. [4]
Highlighted rows indicate those entries in which the three-letter codes differ from column to column. The last column indicates the number of codes present followed by letters to indicate which codes are present (O for Olympic, F for FIFA, and I for ISO) and dashes when a code is absent; capital letters indicate codes which match; lower case ...
TESTU01 offers several batteries of tests including "Small Crush" (which consists of 10 tests), "Crush" (96 tests), and "Big Crush" (106 tests). The specific tests applied by each battery are detailed in the user's guide. [3] On a 1.7 GHz Pentium 4 running Red Hat Linux 9.0, for a simple RNG, Small Crush takes about 2 minutes. Crush takes about ...
