  1. 21. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Guillaume Larrat; [2023]
    Nyckelord :Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

    Sammanfattning : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. LÄS MER

  3. 22. Itô Diffusions on Level Sets

    Master-uppsats, Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data science

    Författare :Coën Olofsson; [2023]
    Nyckelord :Itô diffusions; level sets; stochastic differential geometry; numerical schemes;

    Sammanfattning : Itô diffusions that move on level sets of functions in Rn, which we have called level processes, are an overlooked variant of the classical Itô processes. These processes find themselves nestled between the study of regular Itô diffusions in Rn and diffusions which are bound to smooth manifolds. LÄS MER

  4. 23. Perceptions of Virtual Reality Technologies Within Elderly Care

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Stefan Bajin; Simon Solberg; [2023]
    Nyckelord :virtual reality; elder care; mental health; healthcare system; perceptions of vr;

    Sammanfattning : The Swedish healthcare system is strained today, along with a rise in the number of elderly people in the country. Aside from the expected physical ailments facing this group, mental health issues such as depression are also common amongst older adults. LÄS MER

  5. 24. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data

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

    Författare :Alfred Nilsson; [2023]
    Nyckelord :Deep Learning; Vision-Transformers; Echocardiography; Feature Selection; Gumbel-Softmax; Concrete Autoencoders; Regression; Djupinlärning; Vision-Transformers; Ekokardiografi; Feature Selection; GumbelSoftmax; Concrete Autoencoders; Regression;

    Sammanfattning : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. LÄS MER

  7. 25. Hitting the Target: An Analysis of Inflation Targeting Policies

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Elin Roslund; Victoria Benckert; [2023]
    Nyckelord :Inflation Target; Inflation; Generalized Synthetic Control Method; Discretion; Taylor Rule;

    Sammanfattning : Acknowledging that world inflation reached its highest levels in decades in 2022, this paper investigates how the adoption of an inflation targeting regime has affected the inflation level and the inflation variability for a sample of five advanced economies from 1980 until the end of 2020. This paper discusses the implications of inflation targets in relation to the relative output growth across inflation targeting and non-inflation targeting economies to further contribute to the debate about its efficacy.
