  1. 1. Local Voltage Control in Converter Based PV Generation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Charlotta Sporre; [2024]
    Nyckelord :distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

    Sammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER

  3. 2. Limited angle reconstruction for 2D CT based on machine learning

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

    Författare :Eric Oldgren; Knut Salomonsson; [2023]
    Nyckelord :CT; computed tomography; limited angle; machine learning; limited data; ill posed problem; inverse problem;

    Sammanfattning : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

  4. 3. The Limits to Cognitive Social Capital as a Protective Factor: Examining the Buffering Effects between Intimate Partner Violence and Depression among Congolese Refugee Women

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Camila Rodriguez Manrique; [2023]
    Nyckelord :intimate partner violence; depression; functional impairment; perceived social support; cognitive social capital; refugee women; Social Sciences;

    Sammanfattning : Intimate partner violence (IPV) is the most common form of violence against women globally, with high prevalence rates among refugee communities. Previous literature indicates its relation to negative mental health outcomes such as depression and the potential help of social protective factors. LÄS MER

  5. 4. Minimal Cantor sets

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Jacob Nordin Gröning; [2023]
    Nyckelord :Cantor sets; Minimal Cantor sets; Inverse limits; Combinatorial Covers; Cantor mängder; Minimala Cantor mängder; Inversa gränser; Kombinatoriska övertäckningar;

    Sammanfattning : A Cantor set is a topological space which admits a hierarchy of clopen covers. A minimal Cantor set is a Cantor set together with a map such that every orbit is dense in the Cantor set. In this thesis we us inverse limits to study minimal Cantor sets and their properties.

  7. 5. Profinite groups

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Juan Moreno Poncela; [2023]
    Nyckelord :Profinite Groups; Infinite Galois Theory; Mathematics and Statistics;

    Sammanfattning : This thesis provides a comprehensive study of profinite groups, which are fascinating mathematical objects that have attracted significant interest in modern algebraic research. Profinite groups are infinite generalizations of finite groups and share many similarities with them. LÄS MER
