  1. 1. Random curves and their scaling limits

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Jonatan Wächter; [2023]
    Nyckelord :Stochastic processes; Schramm-Loewner-Evolution; Random Walk; Brownian Motion; Harmonic Explorer;

    Sammanfattning : We focus on planar Random Walks and some related stochastic processes. The discrete models are introduced and some of their core properties examined. We then turn to the question of continuous analogues, starting with the well-known convergence of the Random Walk to Brownian Motion. LÄS MER

  3. 2. Experimental Procedures for Operational Modal Analysis of a Power Pack on a Drill Rig

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Oscar Nilsson; [2017]
    Nyckelord :Operational modal analysis; OMA; engine sweep; modal identication; harmonic scaling;

    Sammanfattning : All structures have modal properties such as natural frequencies and damping. In engineeringit is often of interest to estimate these modal properties for certain structures, to be used whenmodelling for example fatigue. This is done by computing them from finite element models, by using experimental measurements or both. LÄS MER

  4. 3. Effect of Axial Gap Distance on Transonic Compressor Performance

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Joseph Sadek; [2015]
    Nyckelord :Axial Gap Distance; Transonic Compressors; Aerodynamic Performance; CFD; Harmonic Balance; inter-row gap;

    Sammanfattning : The modern trend of gas turbines design is towards lighter, highly efficient,and more compact engines. Such situation imposes on engineers to continuouslysearch for improved and optimum designs. The thesis presented aims at researching possible performance improvements regarding axial gapdistance in transonic compressors. LÄS MER

  5. 4. Decline Curve Analysis of Shale Oil Production : The Case of Eagle Ford

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Linnea Lund; [2014]
    Nyckelord :shale oil; unconventional oil; shale; decline curve analysis; DCA; eagle ford;

    Sammanfattning : Production of oil and gas from shale is often described as a revolution to energyproduction in North America. Since the beginning of this century the shale oilproduction has increased from practically zero to currently supply almost half of theU.S. oil production. LÄS MER
