  1. 1. En studie på traceurers maximala styrka och explosiva styrka : att mäta hoppförmåga inom Parkour/Freerunning med Isometric Mid-Thigh Pull och Countermovement Jump

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

    Författare :Don Piili; Tobias Nilsson; [2023]
    Nyckelord :Parkour; Freerunning; PK; PK FR; IMTP; Isometric midthigh pull; CMJ; counter movement jump; Newton; Traceur; traceuse; Hoppförmåga; GIH; LTIV; tränarlänkövrigt;

    Sammanfattning : Syfte: Syftet för studien var att undersöka om isometric mid-thigh pull (IMTP) tillsammans med (CMJ) kan anses som lämpliga testmetoder för att mäta prestation i hoppförmåga inom parkour/freerunning (PK/FR). Vi undersökte detta genom att mäta traceurers maximala styrka och explosiva styrka i de nedre extremiteterna, för att sedan jämföra resultaten med fysiskt aktiva idrottsstudenter på högskolenivå.

  3. 2. 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.

  4. 3. Superluminous magnons in Nickel Oxide

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Jannes van Poppelen; [2023]
    Nyckelord :;

    Sammanfattning : Recent experiments have shown that the magnon velocity over nanoscale distancesin certain antiferromagnetic materials, with NiO in particular, far exceeds the previous theoretical maximum. Antiferromagnetic insulators are excellent candidatesfor spintronic nanodevices due to their exceptionally low energy dissipation, whichcould benefit the future speed at which information is stored.

  5. 4. Analysis and time calculations of NC files : Time calculation of Nailing Bridge machine movements

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Julia Rohnér; Emelie Sköld; [2023]
    Nyckelord :CNC-Machines; NC files; time calculations;

    Sammanfattning : Randek is a company that develops machines. The machines are used to build prefabricated houses. They have developed a CNC machine called Nailing Bridge that creates house walls. One of their issues is that they must predict the time it takes to build a wall because their customers need to know how long it takes to deliver their house. LÄS MER

  7. 5. Phase Unwrapping MRI Flow Measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Mio Liljeblad; [2023]
    Nyckelord :phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Sammanfattning : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. LÄS MER
