  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

  3. 2. A Force Directed Placement Method Including Angular Resolution and Bond Overlap

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Ludvig Sundström; [2016]
    Nyckelord :;

    Sammanfattning : This study presents a variant of the "spring method" for visualizing simple and undirected graphs. In addition to elementary spring energies, we introduce continuous energy terms for bond angles and bond overlap. To find a good graph layout, the energy of a graph is minimized using an optimization technique including the conjugate gradient method. LÄS MER

  4. 3. Steering System Modelling for Heavy Duty Vehicles

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Rickard Sjölund; Nicklas Vedin; [2015]
    Nyckelord :Advanced Driver Assistance System; Steering System; Lane Keep Assist; Power Steering Gear; Physical Modelling; Hydraulic Power Assist; Bond Graph;

    Sammanfattning : Future heavy duty vehicles will be designed and manufactured with improved Advanced Driver Assistance Systems, ADAS. When developing ADAS, an accurate model of the vehicle dynamics greatly simplifies the development process. One element integral to the vehicle lateral dynamics and development of ADAS is the steering system. LÄS MER
