  1. 1. Juice/JDC ion measurement perturbations caused by spacecraft charging in the solar wind and Earth’s magnetosheath

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Derek van Winden; [2024]
    Keywords : Juice; Jupiter Icy Moons Explorer; JDC; Jovian plasma Dynamics and Composition analyzer; Particle Environment Package; PEP; Jupiter; Ganymede; Callisto; Europa; solar wind; magnetosheath; spacecraft charging; Spacecraft Plasma Interaction Software; SPIS; charging; plasma; measurement perturbations; perturbation; distortion; particle detector; Institutet för Rymdfysik; IRF; Dublin Institute for Advanced Studies; DIAS; European Space Agency; ESA;

    Abstract :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. READ MORE

  3. 2. Fine-Tuning Parameters in CT

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Anton Adelöw; Tomas Nordström; [2023]
    Keywords : ;

    Abstract : Computed tomography (CT) is a medical imaging technique that usesX-rays to obtain a reconstruction of an object. The term acquisition ge-ometry refers to the arrangement of imaging sensors and the X-ray sourceas well as the procedure used for data collection. READ MORE

  4. 3. Flight Dynamics Software Industrialisation for Inclined Orbits

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Pierrick Houede; [2023]
    Keywords : flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

    Abstract : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. READ MORE

  5. 4. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

    University essay from Linköpings universitet/Informationskodning

    Author : Oscar Pihl; [2023]
    Keywords : spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

    Abstract : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

  6. 5. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE
