  1. 1. The paint loss of Callmander’s stained glass windows: An investigation of the prevalence and causes behind the paint loss on Callmander and Svenska Glasmåleri AB’s stained glass windows

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Victor Eisfeldt; [2024-02-06]
    Nyckelord :Grisaille; Stained-glass; Callmander; Vitreous Paint;

    Sammanfattning : This MA-thesis investigates the loss of grisaille paint in the stained-glass windows created by the artist Reinhold Callmander and Svenska Glasmåleri AB, with the aim of understanding the prevalence as well as the reasons behind the issue. Stained glass has historically been in the periphery of conservation. LÄS MER

  3. 2. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  4. 3. Decay Chains of Fast Alpha Emitters in the Actinide Region

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Tanvir Sayed; [2024]
    Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

  5. 4. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  7. 5. Designing User Interfaces for Increased Depth Perception in Remote Crane Operation

    M1-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johan Harju; [2024]
    Nyckelord :Depth perception; teleoperations; view perspective; graphical user interface; remote operation;

    Sammanfattning : This study investigates different design choices for graphical user interfaces meant to improve depth perception in remote crane operation through measuring efficiency and user experience. To achieve this, three different graphical user interface designs were created and implemented into a cargo port simulator within the game engine Unity. LÄS MER
