1. 16. Flexural strength of dental restoratives

   Master-uppsats, Umeå universitet/Institutionen för odontologi

   Författare :Mikael Blennow; Ahmed Al-Ahmed; [2023]
   Nyckelord :Flexural strength; porosity;

   Sammanfattning : Background: New dental restorative material, “Cention Forte” and “Admira Fusion” have been available on the market for quite some time but are still new in comparison with traditional resin-based composite, “Ceram.x Spectra ST” and glass ionomer cement, “GC Fuji II LC”. LÄS MER

3. 17. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Harald Agelii; [2023]
   Nyckelord :Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

   Sammanfattning : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. LÄS MER

4. 18. Quality enhancement of time-resolved computed tomography scans with cycleGAN

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

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

   Sammanfattning : 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. LÄS MER

5. 19. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

   Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Författare :Annika Silvennoinen; [2023]
   Nyckelord :Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

   Sammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER

7. 20. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zhenyu Li; [2023]
   Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER
