  1. 1. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Mussie Habtemariam Zeru; [2024]
    Nyckelord :Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

    Sammanfattning : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

  3. 2. Improving the experimental setup for ultrasound-optical tomography imaging

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ibtisam Dahir Ahmed; [2023]
    Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

  4. 3. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

    Författare :Ashray Ugle; [2023]
    Nyckelord :Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

  5. 4. Re-processing Reflection Seismic Data at a Quick-clay Landslide Site in Southwest Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Zhaochen Mu; [2022]
    Nyckelord :reprocess; reflection seismic; tomography; quick-clay; landslide;

    Sammanfattning : This MSc thesis reprocessed seismic data collected at a site near the Gota River in 2011, focusing on two lines. The two seismic lines ran through a landslide scar zone for a total length of 1 km, both of which used dynamite as the seismic source. LÄS MER

  7. 5. High Resolution Quality Enhancement of Digitized Artwork using Generative Adversarial Networks

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

    Författare :Dennis Magnusson; [2022]
    Nyckelord :Image enhancement; Image style transfer; Image superresolution; Machine Learning; Bildförbättring; Bildstilöversättning; Bildsuperupplösning; Maskininlärning;

    Sammanfattning : Digitization of physical artwork is usually done using image scanning devices in order to ensure that the output is accurate in terms of color and is of sufficiently high resolution, usually over 300 pixels per inch, however the usage of such a device is in some cases unfeasible due to medium or size constraints. Photography of the artwork is another method of artwork digitization, however such methods often produce results containing camera artifacts such as shadows, reflections or low resolution. LÄS MER
