1. 6. Quality enhancement of time-resolved computed tomography scans with cycleGAN

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

   Author : Johannes Stubbe; [2023]
   Keywords : carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

   Abstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE

3. 7. Investigation of Antenna Radomes in Low Earth Orbits

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Mathias Manohar Gren; [2023]
   Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

   Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

4. 8. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Yoana Ilarionova; [2023]
   Keywords : Physics and Astronomy;

   Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE

5. 9. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Klas Junskog; [2023]
   Keywords : oscillators; mm-wave; radar; Technology and Engineering;

   Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

6. 10. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Johannes Hall; Albin Larsson; [2023]
   Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

   Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE
