1. 1. Evaluation of SLAM based mobile laser scanning and terrestrial laser scanning in the Kiruna mine : A comparison between the Emesent Hovermap HF1 mobile laser scanner and the Faro Laser Scanner Focus3D X 330 terrestrial laser scanner

   Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

   Författare :Claes Gustafsson; [2023]
   Nyckelord :Terrestrial laser scanning; mobile laser scanning; simultaneous localization and mapping; underground mapping; Kiruna mine.;

   Sammanfattning : The mining industry has over the last few decades seen a drastic increase in the usage of laser scanning technologies as a way of creating 3D maps of the mines being exploited. Underground mapping in places such as mines has become more prevalent as the technology has progressed and made it easier to generate highly detailed point clouds faster. LÄS MER

3. 2. Total body perfusion imaging with 15O-water PET

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Anna Åhlström; [2023]
   Nyckelord :;

   Sammanfattning : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. LÄS MER

4. 3. Reconstruction of Accelerated Cardiovascular MRI data

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Hussnain Khalid; [2023]
   Nyckelord :medical imaging; deep learning; CNN; Magnetic resonance imaging; MRI; Cardiac MRI; Cardiac; Cardiovascular; reconstruction; 4D flow MRI; Parallel Imaging; Compressed Sensing; FlowVN; Flow Variational Network; K-space; Reference images; sensitivity maps; Respiratory motion; undersampled images;

   Sammanfattning : Magnetic resonance imaging (MRI), is a noninvasive medical imaging testing techniquewhich is used to produce detailed images of internal structure of the human body, includingbones, muscles, organs, and blood vessels. MRI scanners use large magnets and radiowaves to create images of the body. LÄS MER

5. 4. Feature-Aware Point Transformer for Point Cloud Alignment Classification : Pose your pose to FACT

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Ludvig Dillén; [2023]
   Nyckelord :point cloud alignment; point cloud alignment classification; alignment validation; point cloud; map validation; map quality; misalignment recognition; alignment quality; point transformer; Sinkhorn divergence; differential entropy; point cloud co-visibility; point cloud visibility; SLAM; point cloud registration; point cloud density;

   Sammanfattning : As the demand for 3D maps from LIDAR scanners increases, delivering high-quality maps becomes critical. One way to ensure the quality of such maps is through point cloud alignment classification, which aims to classify the alignment error between two registered point clouds. LÄS MER

7. 5. Investigating teacher's use of assistive technology for teaching children with learning disabilities in Gothenburg

   Master-uppsats, Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

   Författare :Johan Njikem; [2022-11-28]
   Nyckelord :Pedagogical Competence; Gothenburg Municipality;

   Sammanfattning : Aim: The purpose of this study was to investigate teacher’s use of Assistive Technology (AT) to teach children with learning disabilities (LD) in elementary classrooms in the Gothenburg Municipality of Sweden. This thesis assessed classroom availability and use of 16 AT tools for teaching children with learning disabilities, teacher’s attitudes and teacher’s level of pedagogical competence in using AT to teach children with LD in the areas of reading, writing, mathematics and memory / organization disorders.
