Domain-Specific Analog Physical Computing Accelerators
… the fast and efficient generation of non-uniform random variates in hardware. Using simulations and real-world empirical measurements this dissertation shows that software non-uniform random number generation is slow and inefficient, and discusses why this is the case. This dissertation presents …

A Statistical Evaluation of Algorithms for Independently Seeding Pseudo-Random Number Generators of Type Multiplicative Congruential (Lehmer-Class).
<p>To be effective, a linear congruential random number generator (LCG) should produce values that are (a) uniformly distributed on the unit interval (0,1) excluding endpoints and (b) substantially free of serial correlation. It has been found that many statistical methods produce inflated Type I …

Improving the Security of Continuous Variable Quantum Random Number Generators
Random numbers are vital for a wide variety of applications including lotteries, statistical sampling, computer simulations and cryptography. They can also be used to make random decisions required in both quantum key distribution (QKD) and fundamental tests of the foundations of quantum mechanics. …

Photon Arrival Time Quantum Random Number Generation
A quantum random number generator (QRNG) is one which re- lies on a physical process, extracting randomness from the inherent uncertainty in quantum mechanics. This is to be contrasted with current pseudo-random number generators (PRNG), which although useful, are in fact deterministic: they always …

Irrigation cost models to assess the feasibility and potential expansion of large-scale riparian irrigation in Virginia
… fixed and variable irrigation costs were randomized in a uniform and independent distribution using the random number generator in the BASIC language. The design models were simulated using these uniform distributions to build a database representing 3000 observations for each irrigation …
