  1. 1. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    Master-uppsats, KTH/Kemi

    Författare :Arezu Sehati; [2023]
    Nyckelord :Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Sammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER

  2. 2. Determining Protein Conformational Ensembles by Combining Machine Learning and SAXS

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Samuel Eriksson Lidbrink; [2023]
    Nyckelord :AlphaFold; AlphaFold2; SAXS; protein conformational ensembles; machine learning; protein conformations; reweighting; SAXS; AlphaFold; AlphaFold2; proteinkonformationsensembler; maskininlärning; proteinkonformationer; omviktning;

    Sammanfattning : In structural biology, immense effort has been put into discovering functionally relevant atomic resolution protein structures. Still, most experimental, computational and machine learning-based methods alone struggle to capture all the functionally relevant states of many proteins without very involved and system-specific techniques.

  3. 3. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Max Holmberg; Pontus Sundberg; [2022]
    Nyckelord :Aluminium Alloy A205;

    Sammanfattning : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. LÄS MER

  4. 4. Acceleration of Machine-Learning Pipeline Using Parallel Computing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Xavante Erickson; [2021]
    Nyckelord :acceleration; ray; accelerator; numpy; machine-learning; machine; learning; optimization; parallelization; speedup; profiling;

    Sammanfattning : Researchers from Lund have conducted research on classifying images in three different categories, faces, landmarks and objects from EEG data [1]. The researchers used SVMs (Support Vector Machine) to classify between the three different categories [2, 3]. LÄS MER

  5. 5. Development of Novel (Cu,Fe)3O4 Coatings for AISI 441 Solid Oxide Cell Interconnects : Coating optimization and long-term study

    Master-uppsats, KTH/Materialvetenskap

    Författare :Line Larby; [2020]
    Nyckelord :SOC; SOFC; interconnect; Cr evaporation; Cu-Fe coatings; spinel; SOFC; SOC; interkonnektor; bipolär platta; Cr-förångning; Cu-Fe-beläggningar; spinell;

    Sammanfattning : As current environmental challenges are gaining increased attention, development of clean energy solutions is becoming one of the essential strategies to keep within the boundaries of established environmental policies. Solid oxide cell (SOC) technology can provide clean energy conversion and storage when hydrogen is the energy carrier. LÄS MER
