1. 1. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Christian Rotter; Erik Fagerberg; [2023]
   Keywords : additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

   Abstract : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. READ MORE

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

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

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

   Abstract : 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. READ MORE

4. 3. Assessing tree modeling algorithm from terrestrial laser scanning in Rumperöd mixed forest

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stig Sand; [2023]
   Keywords : Terrestrial laser scanning; Hough transform algorithm; TreeLS; Rumperöd; Biology and Life Sciences;

   Abstract : Recent technological advancements have revolutionized tree inventory methods for the forest industry. The development of terrestrial laser scanning (TSL) and automatized tree recognition software to estimate crucial tree parameters such as diameter at breast height (DBH) has made the inventory work faster and more reliable.

6. 5. Simulations and modeling of light propagation in biological tissue

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Emma Hjörneby; [2023]
   Keywords : Technology and Engineering;

   Abstract : The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax.
