A random seed (or seed state, or just seed) is a number (or vector) used to initialize a pseudorandom number generator.. A pseudorandom number generator's number sequence is completely determined by the seed: thus, if a pseudorandom number generator is later reinitialized with the same seed, it will produce the same sequence of numbers.
The R sets [3] are a class of bi-mode multiple units (EDMU) being built by as part of the Regional Rail Project to replace NSW TrainLink's ageing Xplorer and XPT fleets for long-distance services, as well as Sydney Trains' Endeavour fleet for diesel intercity services.
SPSS: A dialog box for Propensity Score Matching is available from the IBM SPSS Statistics menu (Data/Propensity Score Matching), and allows the user to set the match tolerance, randomize case order when drawing samples, prioritize exact matches, sample with or without replacement, set a random seed, and maximize performance by increasing ...
The set of real numbers, sometimes called "the reals", is traditionally denoted by a bold R, often using blackboard bold, . [ 2 ] [ 3 ] The adjective real , used in the 17th century by René Descartes , distinguishes real numbers from imaginary numbers such as the square roots of −1 .
Seed vigor is a measure of the quality of seed, and involves the viability of the seed, the germination percentage, germination rate, and the strength of the seedlings produced. [ 47 ] The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth.
An improvement to (single) spaced seeds was first demonstrated by PatternHunter in 2002 [1] where a set of spaced seeds were used, in which a "hit" was called whenever one of the set matched. PatternHunter II, in 2003, demonstrated that this approach could offer higher sensitivity than BLAST while maintaining similar speed. [ 9 ]

The first step in region growing is to select a set of seed points. Seed point selection is based on some user criterion (for example, pixels in a certain grayscale range, pixels evenly spaced on a grid, etc.). The initial region begins as the exact location of these seeds.
