  1. 1. Flight dynamics multi-mission software development for optical link planning and execution

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

    Författare :Giacomo Dal Toso; [2023]
    Nyckelord :Generic Planning Tool; Visibility Service; Link Support Service; Visibility Windows; Flight Dynamics; Mission Planning;

    Sammanfattning : The Generic Planning Tool (GPT) is a new software package being developed by the Flight Dynamics team at DLR. In an era where laser communications are becoming more and more relevant to data transmission for space missions, the GPT’s purpose is to compute highly accurate visibility windows and provide a wide variety of support information for both satellite-to-ground and inter-satellite links.

  4. 3. Simulation of Quantum Cascade Lasers

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Zakaria Mohamed; [2023]
    Nyckelord :Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Sammanfattning : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. LÄS MER

  5. 4. Beräkning av blockstyrlager inom vattenkraft

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Anton Knipbo; Henrik Vall; [2023]
    Nyckelord :;

    Sammanfattning : Examensarbetet utförde på uppdrag av Rainpower AB i Kristinehamn vilka ägs av Aker Solutions som är en heltäckande leverantör för allt inom vattenkraft. Företaget hade ett beräkningsprogram för beräkning av radiella blockstyrlager inom vattenkraft som behövde uppdateras, göras mer användarvänligt och skapa tydligare utdata. LÄS MER

  7. 5. Convection in a spherical shell under rapid rotation: numerical simulations

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Camille Rambert; [2022]
    Nyckelord :convection; rapid rotation; spectral methods; spherical geometry;

    Sammanfattning : A numerical method for solving the buoyancy-driven magneto-convection equations in a rapidly rotating spherical shell is presented. The method is implemented through a FORTRAN 90 program, based on a FORTRAN 66 code written by Hollerbach [International Journal for Numerical Methods in Fluids, 32 (2000)] and partially translated in FORTRAN 90 by Riquier.
