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. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Íñigo de Loyola Chacartegui Rojo; [2023]
   Keywords : Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

   Abstract : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

4. 3. Improving Objectivity and Reliability of Observational Risk Assessment Tools by using Technical Instruments

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Cephas Charsmar-Etor; [2023]
   Keywords : Direct measurement instruments; Observational instruments; Body segments and postures; Inertial measurement unit; Wearable sensors;

   Abstract : Ergonomic assessments to determine risks of work-related musculoskeletal disorders as well as to compare designs of work-tasks and workstations, are imperative for high sustainability and productivity in any given industry. Hence, assessment tools that can objectively and reliably capture postures, joint angles and muscle activities play very important role in properly determining risks relating to work and various tasks.

5. 4. Using forest reflectance modelling to estimate albedo for narrow-view satellites

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

   Author : Nick Bergmans; [2023]
   Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

   Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

6. 5. Estimating stellar limb darkening using exoplanet transits

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Sora Ishida; [2023]
   Keywords : Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

   Abstract : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. READ MORE
