Numerical Simulation of Bed Topography and Flow Field around Double Rows-Barriers and Gabion Groin in the Direct Channel using Flow-3D [PDF]

open access: yesمحیط زیست و مهندسی آب, 2019
The erosion of bed and river banks and sediment transport is one of the reasons for migration and changes in river morphology, which causes changes in the quality and quantity of flow. Groins are among the rivers' structures that extend from the coast to

Analyses of unpredictable properties of a wind-driven triboelectric random number generator

open access: yesScientific Reports, 2023
Wind-driven triboelectric nanogenerators (W-TENGs) are a promising candidate for an energy harvester because wind itself possesses unexhausted, ubiquitous, and clean properties.

Xorshift RNGs [PDF]

open access: yesJournal of Statistical Software, 2003
Description of a class of simple, extremely fast random number generators (RNGs) with periods 2k - 1 for k = 32, 64, 96, 128, 160, 192. These RNGs seem to pass tests of randomness very well.

A Dual Entropy-Based Digital Random Number Generator

open access: yesIEEE Access, 2021
This paper introduces the dual-entropy method for oscillator-based digital random number generators (RNG). The standard model for elaborating jitter-based RNG is expanded to account for the sampling time uncertainty.
