  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. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  7. 5. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Yujun Han; [2023]
    Nyckelord :Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Sammanfattning : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. LÄS MER
