  1. 1. 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

  3. 2. Measuring copper abundances in the Galactic Bulge

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Nikolei Höglinger; [2024]
    Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  4. 3. IMG-elementet och PICTURE-elementet som bildimplementationstekniker inom m-handel

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Ida Wallin; [2023]
    Nyckelord :Responsiv webbdesign; media queries; flexible image; PICTURE-elementet; IMG-elementet; e-handel;

    Sammanfattning : Fler går över till att använda mobila enheter för att besöka webben samtidigt som e-handelsmarknaden växer. Till skillnad mot fysiska butiker så saknar ofta butiker på nätet möjligheten till att ge tillräcklig information om produkterna. LÄS MER

  5. 4. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

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

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  7. 5. A shed, a dock and a boat : a design proposal for a harbor in Bohuslän with focus on cultural heritage

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Nina Littmann; [2023]
    Nyckelord :Bohuslän; cultural heritage; harbor design; development; Tanums kommun; docks;

    Sammanfattning : This thesis presents a design proposal for a new harbor in Bohuslän.The area holds high historical and aesthetic values. The project site has been proposed by the municipality for the development of a new harbor, to meet increasing demand for mooring in the area. LÄS MER
