  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?

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för fysiologi, nutrition och biomekanik

    Author : Maria Vitazka; [2023]
    Keywords : 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;

    Abstract : 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. Implementing Kalman Filtering Algorithms for Estimating Clamp Force on a Test Rig : Testing the Power and Limitations of Unscented Kalman Filter-based Estimations

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tim Naser; [2023]
    Keywords : Clamping Froce; Kalman Filtering; Unscented Kalman Filtering; Tightening; Consequence of User Errors During Tightening; Velocity Profiles; Klämkraft; Kalman Filtrering; Unscented Kalman Filtrering; Åtdragning; Konsekvens av Användarfel Under Åtdragning; Hastightersprofiler.;

    Abstract : his study explores clamp force estimation using Unscented Kalman Filtering (UKF) in torque-controlled tightening scenarios with various velocity profiles. Previous research has explored the impact of velocity levels on target torque and clamping force, but only using hand-held tools. READ MORE

  4. 3. Turbulent Boundary Layers Modelling with Deep Operator Networks

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yu-Cheng Lu; [2023]
    Keywords : Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

    Abstract : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

  5. 4. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Aayush Desai; [2023]
    Keywords : Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Abstract : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. READ MORE

  6. 5. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE
