  1. 1. Battery Degradation and Health Monitoring in Lithium-Ion Batteries: An Evaluation of Parameterization and Sensor Fusion Strategies

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Simon Saber; [2024]
    Nyckelord :model-based diagnostics; modellbaserad diagnostik;

    Sammanfattning : The purpose of this project was to perform model-based diagnosis on Li-ion batteries using real-world data and sensor fusion algorithms. The data used in this project was collected and distributed by NASA and mainly consists of voltage and current measurements collected on numerous batteries that were repeatedly charged and discharged from their beginning of life, and until surpassing their end of life.

  3. 2. A European Material Kuznets Curve

    Kandidat-uppsats, Stockholms universitet/Nationalekonomiska institutionen

    Författare :Pyry Järvinen; Emil Fernström; [2023]
    Nyckelord :Material Kuznets Curve; Environmental Kuznets Curve; Economic Growth; Economics Development; Material Footprint; Emissions; Sustainable Growth; Decoupling; Europe;

    Sammanfattning : This bachelor thesis investigates the correlation between 28 European countries’material footprints (MF), as proxied by their Raw Material Consumption (RMC)per capita, and the environmental impact indicated by their carbon dioxide (CO2)emissions per capita, respectively, with their economic development, measured bytheir purchase power parity adjusted gross domestic product (GDP) per capita,during the period of 2008 to 2019. Specifically, through the theoretical frameworkof the Environmental Kuznets Curve (EKC) and by utilizing Fixed EffectsOrdinary Least Squares regression models as well as Pooled Mean Groupestimation, the thesis asks whether or not evidence can be found for the possibleexistence of an EKC, an inverted-U shaped relationship between environmentaldegradation and economic development, within this European context.

  4. 3. Coverage initiations : an exploratory casestudy

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

    Författare :Lina Ek; Maria Karlsson Osipova; [2023]
    Nyckelord :Commissioned equity research; Initiation report; Event study; Abnormal return; Trading volume; Uppdragsanalys; Initieringsrapport; Eventstudie; Abnormal avkastning; Handelsvolym;

    Sammanfattning : This master thesis is exploring the influence of coverage initiation reports issued by commissioned equity research analysts on stock prices and trading volumes. Equity research actors, with their expertise and skill, are providing the market with valuable information and filling the knowledge gaps that investors may have. LÄS MER

  5. 4. Magnetic field of the magnetic chemically peculiar star V1148 Ori

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

    Författare :Kristoffer Pettersson; [2023]
    Nyckelord :chemically peculiar star; magnetic fields; deconvolution; zeeman effect; polarization;

    Sammanfattning : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. LÄS MER

  7. 5. Channel Estimation Optimization in 5G New Radio using Convolutional Neural Networks

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :David Adolfsson; [2023]
    Nyckelord :Channel Estimation; 5G NR; CNN; Kanalestimering; 5G NR;

    Sammanfattning : Channel estimation is the process of understanding and analyzing the wireless communication channel's properties. It helps optimize data transmission by providing essential information for adjusting encoding and decoding parameters. LÄS MER
