  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. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

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

    Författare :Kun Feng; [2023]
    Nyckelord :ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

    Sammanfattning : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. LÄS MER

  4. 3. Effects of automation in railway on the capacity : At the example of the S-Bahn Stuttgart

    Master-uppsats, KTH/Transportplanering

    Författare :Tim Niku Pourian; [2023]
    Nyckelord :;

    Sammanfattning : Passenger numbers in rail transportation and the need for transportation of goods hasbeen rising over the last years. After a breakdown during the years of the pandemicthe need for transportation on rail has almost recovered and numbers are rising again. LÄS MER

  5. 4. Temperaturreglerande ekosystemtjänster i parker : En jämförande fallstudie av Malmö och Stuttgart

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Annika Pettersson; Frida Paulsson; [2021]
    Nyckelord :temperaturreglerande ekosystemtjänster; parker; hållbar utveckling; urbanisering; UHI; jämförande fallstudie;

    Sammanfattning : Urbanization could have a negative impact on sustianble urban development due to the effect on human and ecosystem health. A possible strategy that can decrease temperature and create sustainable societies is through construction of parks in urban areas. LÄS MER

  7. 5. FE modeling of glulam beams with mechanical slotted-in steel plate connections.

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Musaab Mahjoub; [2021]
    Nyckelord :Timber joints; Slotted-in steel plate connections; Python scripting; FEM; Abaqus.;

    Sammanfattning : The mechanical behavior of timber beams with a slotted-in steel plate connection is studied by creating a numerical model that is able to simulate the global bending behavior, the global load carrying capacity and the nonlinear plastic fastener force distribution in the connection. Experimental results from Material Testing Institute (MPA), University of Stuttgart were used to verify the simulation results from this study. LÄS MER
