Introduction Have you played a video game lately? Purchased something on the web? Trained a Neural Network? Used a Genetic Algorithm for optimization? Run software from Microsoft? Applied textures to a photograph? Played the stock market? If the answer is “yes” to any of these questions, Random Number Generator (RNG) have affected your life. Can you trust your Random Number Generator? Can you t...

The ANSI X9.17/X9.31 random number generator is a pseudorandom number generator design based on a block cipher and updated using the current time. First standardized in 1985, variants of this PRNG design were incorporated into numerous cryptographic standards over the next three decades. It remained on the list of FIPS 140-1 and 140-2 approved random number generation algorithms until January 2...

This study considers the self-consistent formation and dynamics of electron clouds interacting with a background neutral gas through elastic inelastic (ionization) collisions in coaxial geometries similar to gyrotron guns. These remain axially trapped as result crossed magnetic field lines electric equipotential creating potential wells those used Penning traps. Contrary standard traps, this st...

The turbulent flow in a tangential inlet / tangential outlet vortex tube is numerically simulated using a modified   k turbulence model. The results are compared to experimental measurements from literature. The modified model shows better agreement with the local tangential velocity measurements compared to the standard and RNG   k turbulence models. The flow structure is also demonstrated...

RNGSSELIB: Program library for random number generation. More generators, parallel streams of random numbers and Fortran compatibility. Abstract In this update, we present the new version of the random number generator (RNG) library RNGSSELIB, which, in particular, contains fast SSE real-izations of a number of modern and most reliable generators [1]. The new features are: i) Fortran compatibil...

Numbers are thought to be spatially organized along a left-to-right horizontal axis with small/large numbers on its left/right respectively. Behavioral evidence for this mental number line (MNL) comes from studies showing that the reallocation of spatial attention by active left/right head rotation facilitated the generation of small/large numbers respectively. While spatial biases in random nu...

Single-Instruction, Multiple-Data (SIMD) random number generators (RNGs) take advantage of vector units to offer significant performance gain over non-vectorized libraries, but they often rely on batch production of deviates from distributions with fixed parameters. In many statistical applications such as Gibbs sampling, parameters of sampled distributions change from one iteration to the next...

In this paper, we explore and analyze the structure and functions of Random Number Generator (RNG) in Windows and Linux opreating systems. And compare the capabilities of their RNGs. It expected that this research would contribute to awareness of the quality and security of the random number generators implemented in Linux and Windows operating systems. It provides unbiased academic research in...

Harvesting a winter rye energy cover crop (Secale cereale L.) could help sustain growing food and demand, provide new revenue streams, enhance ecosystem services without inducing land-use change. A two-year field experiment with three planting methods N fertilization rates (0, 60, 120 kg ha−1) that produced >5.0 Mg ha−1 yr−1 of biomass was evaluated for (1) fresh anaerobically digested forag...
