  1. 1. Predicting Quality of Experience from Performance Indicators : Modelling aggregated user survey responses based on telecommunications networks performance indicators

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

    Författare :Christian Vestergaard; [2022]
    Nyckelord :Quality of Experience; Telecommunication; Regression; Long Short Term Memmory; Clustering; K-means; Gaussian Mixture Models; Användarupplevelse; Telekommunikation; Regression; Long Short Term Memmory; Klusteranalys; K-means; Gaussian Mixture Models;

    Sammanfattning : As user experience can be a competitive edge, it lies in the interest of businesses to be aware of how users perceive the services they provide. For telecommunications operators, how network performance influences user experience is critical. To attain this knowledge, one can survey users. LÄS MER

  3. 2. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Joachim Neguembor; [2022]
    Nyckelord :Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

    Sammanfattning : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. LÄS MER

  4. 3. Sum-Product Network in the context of missing data

    Master-uppsats, KTH/Matematisk statistik

    Författare :Pierre Clavier; [2020]
    Nyckelord :Statistics; Mixture model; Probabilistic Graphical Models; Statistik; Probabilistiska grafiska modeller;

    Sammanfattning : In recent years, the interest in new Deep Learning methods has increased considerably due to their robustness and applications in many fields. However, the lack of interpretability of these models and the lack of theoretical knowledge about them raises many issues. It is in this context that sum product network models have emerged. LÄS MER

  5. 4. The Inequality and Growth Nexus: The Role of Institutions in Mitigating the Negative Effects of Income Inequality

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Audun Gjerde; [2019]
    Nyckelord :Economic growth; income inequality; threshold model; panel data; institutional quality; Business and Economics;

    Sammanfattning : The link between income inequality and economic growth has been a popular topic in the empirical research literature in the past decades. Despite that, a consensus is yet to emerge. LÄS MER

  7. 5. Defining and predicting fast-selling clothing options

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Sara Jesperson; [2019]
    Nyckelord :Apparel retail; B-splines; Gaussian mixture model; Probabilistic prediction; Sales prediction;

    Sammanfattning : This thesis aims to find a definition of fast-selling clothing options and to find a way to predict them using only a few weeks of sale data as input. The data used for this project contain daily sales and intake quantity for seasonal options, with sale start 2016-2018, provided by the department store chain Åhléns. LÄS MER
