  1. 1. Preprocessing for intravoxel incoherent motion analysis in the brain - Signal drift correction

    Master-uppsats,

    Författare :Amina Warsame; [2023-04-17]
    Nyckelord :Medical physics; Diffusion magnetic resonance imaging; dMRI; Intravoxel incoherent motion; IVIM;

    Sammanfattning : Diffusion magnetic resonance imaging (dMRI) is a diagnostic imaging technique that is sensitized to the movement of water molecules in tissues. Intravoxel incoherent motion (IVIM) analysis can be used to estimate blood flow in capillaries from weakly diffusion-weighted data. LÄS MER

  3. 2. Gear Modifications for Optimal Load Distribution

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Raghunath Adimoolam Ganesan; [2023]
    Nyckelord :Lead correction; Profile correction; Even load distribution; Thermal distortion.; helixkorrigering; profilkorrigering; jämn belastningsfördelning; termisk distorsion.;

    Sammanfattning : In the early days of gear manufacturing, engineers aimed to produce teeth as close to the theoretical shape as possible. As machinery advanced and demand for high-speed, high-torque, and quieter transmissions grew, optimizing gear teeth became increasingly important [1]. LÄS MER

  4. 3. PTZ Camera Tampering Correction Using IMUs

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Ludvig Hansson; Måns Lindeberg; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. LÄS MER

  5. 4. Data-driven Dynamic Baseline Calibration Method for Gas Sensors

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

    Författare :Cheng Yang; [2021]
    Nyckelord :CO2 gas sensing; drift; dynamic baseline calibration; time series analysis; data-driven modeling; clustering; classification; CO2 gasavkänning; drift; dynamisk baslinjekalibrering; tidsserieanalys; datadriven modellering; kluster; klassificering;

    Sammanfattning : Automatic Baseline Correction is the state-of-the-art calibration method of non-dispersive infrared CO2 sensing, which is the standard CO2 gas monitoring method. In this thesis, we improve it by introducing the dynamic baseline based on environmental data. LÄS MER

  7. 5. Closed-End Funds and their Net Asset Value over time : A study of the relationship between Swedish closed-end funds' market prices and their underlying assets over a period of time.

    Kandidat-uppsats, Jönköping University/IHH, Nationalekonomi

    Författare :Erik Cederberg; Linus Schnitzer; [2020]
    Nyckelord :Closed-end fund; Net Asset Value; Mean Reversion; Closed-end fund discount; Stock market; Investment strategy; Cointegration; Error Correction;

    Sammanfattning : Closed-end funds (CEFs) are popular investments amongst the Swedish population as they provide diversification to investors and have in many cases historically outperformed the market. In deciding whether to invest in a CEF, the method of valuation differs from classical financial ratios used to value most companies, as the revenue-bringing operations differ significantly. LÄS MER
