  1. 16. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Petter Ideström; [2023]
    Nyckelord :Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Sammanfattning : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. LÄS MER

  3. 17. Quantification of DNA Microballs Using Image Processing Techniques

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Yosef Werede Tedros; [2023]
    Nyckelord :Spot detection; Deep learning; Image processing; smFISH; Gene editing; CRISPR; Rolling circle amplification; Big-FISH; LodeSTAR; DeepSpot; Detektering av punkter; Djupinlärning; Bildbehandling; smFISH; Genredigering; CRISPR; Rolling circle amplification; Big-FISH; LodeSTAR; DeepSpot;

    Sammanfattning : I detta examensarbete användes olika bildbehandlingstekniker för detektion och kvantifiering av DNA-mikrobollar, mer specifikt rolling circle amplification-produkter, på mikroskopibilder. Avsikten med detta arbete var att hjälpa Countagen AB utforska pipelines för bildbehandling för sin produkt där de analyserar utfallet av genredigeringsförsök på ett billigare och snabbare sätt än dagens konventionella sekvenseringsmetoder.

  4. 18. Comparison of Autofocus Methods for Highly Reflective Surfaces : A Case Study on the Inspection of Optical Filters

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

    Författare :Axel Hedvall; [2023]
    Nyckelord :autofocus; reflective surface; optical filter; visual inspection; autofokus; reflekterande yta; optiskt filter; visuell inspektion;

    Sammanfattning : Visual inspection is a crucial final step when manufacturing products, as it determines if a product can be sold or rejected. The inspection is often performed manually by trained inspectors, which is time-consuming and often subjective. By automating the inspection, it can be performed faster and more accurately. LÄS MER

  5. 19. Application of Lamb waves using piezoelectric technique for structure health monitoring

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Simon Mauritz; [2023]
    Nyckelord :Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Sammanfattning : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. LÄS MER

  7. 20. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Jordis Hansen; [2023]
    Nyckelord :XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Sammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER
