1. 1. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :Marcus Stolz; Jonathan Christopher; [2024]
   Nyckelord :Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

   Sammanfattning : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). LÄS MER

3. 2. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Joel Fransson Forsberg; [2023]
   Nyckelord :Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

   Sammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER

4. 3. A comparison between random testing and adaptive random testing

   Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Nicklas Johansson; Ola Aareskjold; [2023]
   Nyckelord :Adaptive random testing; Random testing; Defect detection efficiency; test case generation time;

   Sammanfattning : Software testing is essential for quality assurance, with automated techniques such as random testing and adaptive random testing being cost-effective solutions compared to others. Adaptive random testing seeks to enhance random testing, and there is a conception that adaptive random testing always should replace random testing. LÄS MER

5. 4. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Oscar Pihl; [2023]
   Nyckelord :spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

   Sammanfattning : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

7. 5. RObust Numbers : Temperature's Effect on Ring Oscillators as an Entropy Source

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Tor Arvill; Arber Limani; [2023]
   Nyckelord :;

   Sammanfattning : Ring oscillators as entropy sources for true random number generation could be affected by differences in operating temperatures. This report aims to show a correlation between changes in temperature and the entropy strength of ring oscillators as part of random number generators by utilizing mathematical simulations as well as a physical implementation on a FPGA-board.
