  1. 1. Modelling of the thermal environment and subsystem for a 6U cubesat in GTO orbit

    Magister-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vidhyuth Kasturi Chakravarthy Iyengar; [2020]
    Nyckelord :;

    Sammanfattning : The thermal design of the spacecraft ensures the unobstructed and smoothoperation of the spacecraft under the harsh space conditions. As small satellitesare getting more accessible and standardized, their uses are growing more intomission scenarios which are conventionally used by larger satellites. LÄS MER

  2. 2. Investigating the properties of Planck's radiation law through theoretical and numerical studies

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Alice Graf Brolund; Rebecca Persson; [2018]
    Nyckelord :Planck; Wien; Maxwell-Boltzmann; Monte Carlo; stochastic; distribution; python; black body; radiation; jacobian; cavity radiation; stokastisk; numerisk; fördelning; svart kropp; strålning; svartkroppsstrålning; hålrumsstrålning;

    Sammanfattning : A black body is an ideal object that absorbs all incident electromagnetic radiation and simultaneously emits radiation that only depends on the temperature. The radiation is described by Planck's radiation law and its maximum by Wien's displacement law. LÄS MER

  3. 3. A Physically Based Pipeline for Real-Time Simulation and Rendering of Realistic Fire and Smoke

    Kandidat-uppsats, Stockholms universitet/Numerisk analys och datalogi (NADA)

    Författare :Yiyang He; [2018]
    Nyckelord :Visualization; Physically Based; Pipeline; Real-Time; Dynamic Simulation; Combustion; Fire; Explosion; Smoke; Thick Smoke; Computer Graphics; PDE; Numerical Methods; Grid Based; Navier-Stokes Equation; Imcompressible Fluid; Radiative Transfer Equation; RTE; Volumetric Illumination; Volumetric Rendering; Volumetric Global Illumination; Distant Light Source; Volumetric Global Shadow; Local Shadow Approximation; Black-body Radiation; Poisson Solver; Spectroscopy; Fire Color; Color Reproduction; Tone Mapping; Color Temperature; Color Matching Function; Tristimulus; CIE Standard Observer; Color Space; XYZ; RGB; GPU; GPGPU; ComputeShader; DirectX 12; Unity; C#;

    Sammanfattning : With the rapidly growing computational power of modern computers, physically based rendering has found its way into real world applications. Real-time simulations and renderings of fire and smoke had become one major research interest in modern video game industry, and will continue being one important research direction in computer graphics.

  4. 4. Investigating the GW self-energy of the homogeneous electron gas in real space

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

    Författare :Zhen Zhao; [2018]
    Nyckelord :GW method; self energy; screened-exchange; Coulomb-hole; Physics and Astronomy;

    Sammanfattning : The real space behavior of the GW self-energy in the electron gas model was investigated in this thesis work. The self-energy is naturally decomposed into the screened-exchange and the Coulomb-hole components. LÄS MER

  5. 5. Fluctuations in the CMB through inflation

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Kevin Björk; [2017]
    Nyckelord :;

    Sammanfattning : The goal of this project is to gain a better understanding of the temperature fluctuations observed in the CMB. This goal is reached with the aid of a literature study. LÄS MER
