A fast procedure for generating random numbers by a modification of the Marsaglia-Maclaren method
… generators in order to produce a pseudo random number sequence uniformly distributed in the range [0,2³⁵]. Their method is a considerable improvement compared with the primitive linear congruential method at the cost of greater generation time. In this thesis, a simple modification of the …

Computer methods for generating pseudo-random numbers from Pearson distributions and mixtures of Pearson and uniform distributions
… concerning the generation and testing of pseudo-random numbers. Computer subroutine programs written in FORTRAN IV are given for the generation of pseudo-random numbers from Pearson distributions as well as from any combination of mixtures of two Pearson distributions, a normal distribution with …

The PURGE3, MIX1 and MIX2 subroutines
… been done concerning the generation of pseudo-random numbers. The PURGE3, MIX1, and MIX2 subroutines, written in FORTRAN IV to be run on the IBM 360 computer system, are used for the generation of pseudo-random numbers from a family of Pearson distributions as well as from any combination of …

Pricing European options using Monte Carlo methods
… However, we can model these uncertainties with random numbers. In this pa- per I discuss my implemention of two options-pricing programs using Monte Carlo methods, one for a CPU and the other for a GPU. I also optimize them to reduce their running time. Finally I compare the performance of those …

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. …

Towards smooth particle filters for likelihood estimation with multivariate latent variables
… particle filters are not, even when common random numbers are used for each filter. This is because the same resampling step which drastically reduces the variance of the estimates also introduces discontinuities in the particles that are selected across filters when the parameters change. …

Marketing Strategies for Bed and Breakfast Operations
… study. A sample of 775 of this population was randomly chosen, using a random numbers table. A response rate of 36% was obtained.

An investigation of observed Algorithmic Specified Complexity.
… theory around it predicts the characteristics of random numbers. One evaluated an approach to measuring ASC in pictures by how well it helped in classification, and the other compared predictions and observations of the compressibility of random bitstrings. The ASC of MNIST pictures was estimated …

Controlling Image Synthesis with Emergent and Designed Priors
… unconditional synthesis takes in a tensor of random numbers as input and produces a randomly generated image that mimics real-world content, with little to no way of controlling the result. The work contained in this thesis explores two avenues of obtaining controllable content from image …

A multiple secretary problem with switch costs
… number of applicants appear sequentially in a random order, and the objective is to maximize the sum of the qualities of all hired secretaries over all time. It is assumed that the quality of each applicant is uniformly distributed and any hired secretary can be replaced by a better qualified …

Rollback-able Random Number Generators For The Synchronous Parallel Environment For Emulation And Discrete-event Simulation (spe
Random Numbers form the heart and soul of a discrete-event simulation system. There are few situations where the actions of the entities in the process being simulated can be completely predicted in advance. The real world processes are more probabilistic than deterministic. Hence, such chances are …

PRICING BARRIER OPTIONS - USE OF NUMERICAL SIMULATION METHODS
… simulations were done for both the pseudo random numbers and the deterministic sequences of numbers. These were then used in pricing the outside barrier option. The deterministic sequences showed a faster rate of convergence than the pseudo random numbers that are generally used. Finally a …

An investigation into the relationships between cloze test scores and informal reading inventory scores of fifth grade pupils
… of twenty-two elementary schools by means of a random numbers table. Administrative officials acknowledged the fact that the schools selected were representative of the various socio-economic classes serviced by the school system. Fifty male and fifty female subjects were selected from the total …

A study of the effects of the relationship among caffeine consumption, introversion/extraversion, and trait anxiety on performance
… extraverts (LTA/E). Using a table of random numbers, 30 subjects from each category were selected. These subjects were further randomly assigned to one of the two treatment levels of caffeine.In Phase II of this study each of the 120 subjects consumed either two milligrams of caffeine …

Transport of copiotrophic bacteria in oligotrophic coarse soils: a Monte Carlo analysis
… interface. Specific model parameters were randomly generated using a procedure known to produce either a normal or log-normal distribution of random numbers. Numerous computer simulation runs were completed for hypothetical sandy and loamy sand soils subjected to a 10 year and 100 year rain …

Random obtuse triangles and convex quadrilaterals
… one deals with finding the probability that a random triangle is obtuse in nature. We initially discuss the various ways of choosing a random triangle. The problem is at first analyzed based on random angles (adding to 180 degrees) and random sides (obeying the triangle inequality) which is a …

A Study on Energy Harvesters for Physical Unclonable Functions and Random Number Generation
… issue. Physical unclonable functions (PUFs) and random number generators (RNGs) provide methods to generate security keys for data encryption. Transducers used in the energy harvesting systems of wireless sensor nodes, can generate the PUFs and RNGs. These transducers include piezoelectric …
