  1. 1. Auktoriteter i matematikundervisningen - en inferentialistisk analys av kooperativt lärande

    Kandidat-uppsats, Göteborgs universitet/Institutionen för pedagogik och didaktik

    Författare :Clara Tennby; [2023-04-20]
    Nyckelord :Kooperativt lärande; inferentialism; auktoritet;

    Sammanfattning : Syftet med denna studie har varit att ge en fördjupad förståelse för kooperativt lärande i matematikundervisning genom att visa på de sociala aspekter som avgör vilka beslut elever tar i ett grupparbete. Frågeställningen för studien är: Vilka auktoriteter kan identifieras i ett kooperativt arbetssätt inom mätning och statistik. LÄS MER

  3. 2. Industrial Machine Monitoring: Real-Time Anomalous Sound Event Detection on Low-Powered Devices

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Alexander Magnusson; Anton Andersson; [2023]
    Nyckelord :Anomaly Detection; Sound Event Detection; MFCC; GMM; OCSVM; Mathematics and Statistics;

    Sammanfattning : Traditionally fault detection in industrial machinery has been performed manually by experienced machine operators listening to the machines. However, it is desirable to automate this process to increase efficiency and improve the working environment of the operators. LÄS MER

  4. 3. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Olof Håkman; [2023]
    Nyckelord :Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

    Sammanfattning : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). LÄS MER

  5. 4. Modeling a Relationship between ESG Metrics and Financial Performance for Nordic Publicly-listed Companies

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Cornelia Sparring; Topias Karlsson; [2023]
    Nyckelord :Sustainable finance; ESG variables; ESG score; Accounting-based financial performance; Market-based financial performance; Nordic Compass; Materiality; Hållbar finansiering; ESG variabler; ESG värde; Redovisningsbaserad finansiell prestation; Marknadsbaserad finansiell prestation; Nordic Compass; Materialitet;

    Sammanfattning : This study aims to identify whether a relationship between ESG performance and financial performance exists for Nordic publicly-listed companies, by conducting a multiple linear regression analysis. Also, it will be observed which (if any) ESG variables are of relevance. LÄS MER

  7. 5. Sustainable Investments The effect of ESG and the EU Taxonomy on Nordic stock returns

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Victoria Dinic; Elin Hartman; [2023]
    Nyckelord :ESG; EU Taxonomy; Return on investment ROI; Regression analysis; Environmental; Social; Governance; ESG; EU Taxonomin; Total avkastning; Regressionsanalys; Miljö; Socialt; Bolagsstyrning;

    Sammanfattning : This study analyzes if there is a connection between ESG - which stands for Environmental, Social and Governance, and stock returns over time. The study also analyzes how integrating ESG can impact a company’s competitiveness long term. This is done by researching the following two research questions:1. LÄS MER
