1. Computer-Aided Characterization of Lung - Segmentation and Vessel Tree Analysis Algorithms for Clinical Research Applications
University essay from KTH/FysikAbstract : The initial stage of a lung examination involves the segmentation of a CT image, a process that has been put under a lot of pressure with the high demand for chest scans and accurate segmentations. Current automatic segmentation algorithms are either non-robust for different datasets, not easily accessible, or time-consuming. READ MORE

2. Investigating Sand Dune Location, Orientation and Geomorphometry Through GEOBIA-Based Mapping: A Case Study in Northern Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Climate change has repeatedly been framed as the defining issue of the Anthropocene and with the Arctic changing at unpreceded speed need is high for a profound understanding of the Northern Swedish landscape. Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. READ MORE

3. Dynamics of Selachian (Shark) Dental Morphology During the Early Mesozoic
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The ancestors of all modern day sharks and rays (Neoselachii) may have appeared during the Late Palaeozoic, but their major diversification happened sometime during the Early Mesozoic. Taxonomic evidence places the first neoselachian diversification in the Early Jurassic. READ MORE

4. Diversity and Ecology of a Middle Campanian (Late Cretaceous) Marine Reptile Assemblage from Skåne, Southern Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : This study has looked at an assemblage of fossilised teeth from Mesozoic marine amniotes from the Kristianstad basin in southern Sweden in order to make an estimate of the ecomorph diversity within said assemblage through looking at the morphology of the teeth. This was done as a pilot study to see if further studies would be able to produce worthwhile results. READ MORE

5. Disparity of Early Cretaceous Lamniformes sharks
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The geological range of lamniform sharks stretches from present day species such as Carcharodon carcharias (great white shark) back to the at the moment oldest undoubted fossil finds during the Early Cretaceous. In this paper a geometric morphometric analysis was performed on images of Early Cretaceous lamniform teeth collected from published literature in order to examine the change in disparity (range of morphological variation within a group) throughout the time period.
