  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. Bridging Language & Data : Optimizing Text-to-SQL Generation in Large Language Models

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Författare :Niklas Wretblad; Fredrik Gordh Riseby; [2024]
    Nyckelord :Chaining; Classification; Data Quality; Few-Shot Learning; Large Language Model; Machine Learning; Noise; Prompt; Prompt Engineering; SQL; Structured Query Language; Text-to-SQL; Zero-Shot Learning; Noise Identification;

    Sammanfattning : This thesis explores text-to-SQL generation using Large Language Models within a financial context, aiming to assess the efficacy of current benchmarks and techniques. The central investigation revolves around the accuracy of the BIRD-Bench benchmark and the applicability of text-to-SQL models in real-world scenarios. LÄS MER

  4. 3. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Henry Wittler; [2023-11-29]
    Nyckelord :;

    Sammanfattning : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. LÄS MER

  5. 4. Fano Resonances in Time-Dependent Wells

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Anton Gregefalk; [2023]
    Nyckelord :Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

    Sammanfattning : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. LÄS MER

  7. 5. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fabian Sondh; Erik Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER
