1. 1. Characterization of Lamps of IRF Solar Simulator

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Mrunmayee Sonna; [2023]
   Nyckelord :IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

   Sammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER

3. 2. Effects of solar parabolic- trough collectors in small- scale district heating systems

   Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

   Författare :Alejandro Monterrubio; [2022]
   Nyckelord :Parabolic-trough collector; direct normal radiation; diffuse radiation; insolation; carbon abatement cost; biomass; District Heating; Levelized cost of energy;

   Sammanfattning : Reducing carbon emissions in our societies requires a massive shift towards renewables. In Sweden, biomass is the dominant source for the district heat production, but growing demand for biomass in other sectors may cause pressure on it. LÄS MER

4. 3. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Johan Leygonie; [2021]
   Nyckelord :QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

   Sammanfattning : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. LÄS MER

5. 4. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS

   Master-uppsats, KTH/Rymdteknik

   Författare :Leonardo Ricci; [2021]
   Nyckelord :Solar sail; Solar radiation pressure; Attitude control; Escape trajectory; Centre of pressure; Disturbance Torques; Eclipse.; Solsegel; Solstrålningstryck; Attitydkontroll; Flyktbana; Tryckcentrum; Störningsmoment; Eclipse.;

   Sammanfattning : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.

7. 5. Full Physics Orbital Simulation around Comet Didymos for CubeSat MissionAPEX on HERA, ESA

   L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Jonas Zbinden; [2020]
   Nyckelord :;

   Sammanfattning : We investigate the dynamic environment of the double asteroid system (65803) Didymoswith its satellite Didymos B for stable trajectories of more than 30 days for a model cubesatcalled APEX, foreseen to visit Didymos with the HERA mission, to be launched in 2023.We find semi-stable orbits with lifetimes up to 15 days under the influence of solar radiationpressure.
