16. Origin of blue straggler stars in the Milky Way halo
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. LÄS MER
17. Damage Analysis of Reactive Ion and Atomic Layer Etched Silicon
Magister-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge.

18. Deep Ring Artifact Reduction in Photon-Counting CT
Master-uppsats, KTH/FysikSammanfattning : Ring artifacts are a common problem with the use of photon-counting detectors and commercial deployment rests on being able to compensate for them. Deep learning has been proposed as a candidate for tackling the inefficiency or high cost of traditional techniques. LÄS MER
19. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER
20. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.
