  1. 1. Load-velocity profiles as a predictor of performance level in swimming : What differentiates international elite swimmers from national elite – force capacity or efficiency?

    Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för fysiologi, nutrition och biomekanik

    Författare :Maria Vitazka; [2023]
    Nyckelord :Load-Velocity; Force-Velocity; Force Capacity; Swimming; Biomechanics; Performance indicators; International elite; swimming performance; 1080 Sprint; 1080 Motion; Semi-tethered force measurements; tethered force measurements; maximum velocity; load; force; swimming efficiency;

    Sammanfattning : Aim  The purposes of this study were to investigate if the load-velocity (L-V) profile parameters – force capacity and efficiency - differ between swimmers of different performance level, and to investigate if efficiency is the key performance indicator between international elite and national elite level swimmers.  Method  Fifty-four swimmers (27 female and 27 male) of either regional level, national elite or international elite level, participated in this study.

  3. 2. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

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

    Författare :Lukas Jönsson; [2023]
    Nyckelord :Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Sammanfattning : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  4. 3. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

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

    Författare :Aksel Draguanov Mihaylov; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

  5. 4. Warm dark matter simulations and 21cm astronomy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Melker Marminge; [2023]
    Nyckelord :Warm Dark Matter; N-body Simulation; Power Spectrum; Neutral Hydrogen; Cosmology;

    Sammanfattning : The recent boom in 21cm astronomy has piqued the interest of many, especially cosmologists realizing its applications in their field. This study aims to determine if 21cm astronomy is a good tool for testing the validity of keV WDM models, as well as creating a code capable of simulating keV WDM models from an existing CDM code.

  7. 5. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Björn Arvidsson; [2023]
    Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.
