  1. 1. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hamish Keay; [2023]
    Nyckelord :Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Sammanfattning : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. LÄS MER

  2. 2. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Felicia Törning; [2022]
    Nyckelord :Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

    Sammanfattning : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose.

  3. 3. Accuracy evaluation of using Graph Theory metrics for functional connectivity analysis MCI classification

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Pablo Urquijo Martínez; [2022]
    Nyckelord :;

    Sammanfattning : Mild Cognitive Impairment (MCI) is an intermediate stage between the physiological cognitive deterioration due to ageing and a nonphysiological stage of dementia. MCI has morbidity between 12% and 18% of the population aged over 65 [1]. LÄS MER

  4. 4. Grafklart : Digitalisering av nätverkskarta för analys över hedersvåld och förtryck


    Författare :Marianne Mukanga; [2022]
    Nyckelord :Grafteori; nätverk; nätverksanalys; social nätverksanalys; hedersvåld och förtryck;

    Sammanfattning : Den här studien ämnar minska gapet mellan socialt arbete och datavetenskap. När socialtjänsten utreder fall som handlar om hedersvåld och förtryck så brukar verktyget Nätverkskartan att användas. LÄS MER

  5. 5. Hierarchical Portfolio Allocation with Community Detection

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Kiar Fatah; Taariq Nazar; [2022]
    Nyckelord :Portfolio Allocation; Hierarchical Clustering; Graph Theory; Community Detection; Modern Portfolio Theory; Portföljallokering; Hierarkisk klustring; Grafteori; Community Detection; Modern Portföljteori;

    Sammanfattning : Traditionally, practitioners use modern portfolio theory to invest optimally. Its appeal lies in its mathematical simplicity and elegance. However, despite its beauty, the theory it is plagued with many problems, which are in combination called the Markowitz curse. LÄS MER
