21. High-resolution biomedical phase-contrast tomography
Sammanfattning : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. LÄS MER
22. Students' narratives from graphical artefacts : Exploring the use of mathematics tools and forms of expression in students' graphicacy
Sammanfattning : The research concerns presented in this dissertation addresses aspects of students’ interaction with commonly occurring graphical artefacts in teaching and learning environments. In particular, focus is on how the students make sense of these artefacts in relation to subject specific tools and forms of expression. LÄS MER
23. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Sammanfattning : Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. LÄS MER
24. Renewing power : Including global asymmetries within the system boundaries of solar photovoltaic technology
Sammanfattning : Solar photovoltaic (PV) technology is one of the most favored means of mitigating climate change. At the same time, there is a growing concern over how this technology is both environmentally harmful and unevenly distributed in the world economy. LÄS MER
25. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals
Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER
