  1. 11. Foam Modelling for Child Restraint Systems

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Edwin seby Joshy; Alwin George; [2023]
    Nyckelord :foam modeling; LS-Dyna; Child seat; explicit analysis; drop test;

    Sammanfattning : Computer simulation is an essential tool in the development process of childseats, particularly when it comes to ensuring the safety of child passengers.As awareness regarding child passenger safety continues to grow, the use ofsuitable materials in the development of child seats becomes increasinglycrucial.

  3. 12. Forecasting Football Corner Odds: Statistical Modelling, Betting Strategies and Assessing Market Efficiency

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Gustav Pålsson; Marcus Laurens; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Statistical modelling could be included in a betting strategy where the value of a bet is assessed by comparing model predictions and market odds. This thesis presents several models based on statistical learning methods for predicting the total number of corners in a football match. LÄS MER

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

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

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

    Sammanfattning : 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. 14. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Renato Franze; [2023]
    Nyckelord :Attitude Dynamics; Attitude Control; Earth Observation; Scheduling; Attityddynamik; Attitydkontroll; Jordobservation; Uppgiftsschemaläggning;

    Sammanfattning : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. LÄS MER

  7. 15. Multibody simulations of vibrations in a truck’s steering system

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Marcus Didenbäck; [2023]
    Nyckelord :Multibody simulation; Vibrations; Stiff differential equations; Equations of motion; Lagrange; Vehicle dynamics; Adams; Flerkroppssimulering; Vibrationer; Styva differentialekvationer; Rörelseekva-tioner; Lagrange; Fordonsdynamik; Adams;

    Sammanfattning : This thesis aims to explore if multibody simulations is a suitable method to investigate vibrations in the steering system of trucks. Vibrations in the steering system and subsequently in the steering wheel is a common issue that automotive manufacturers face. LÄS MER
