1. The Earth : climate and anthropogenic interactions in a long time perspective
Sammanfattning : The Earth is a highly complex and dynamic system. Life has shaped the entire planet and evolved in response to living conditions. Ecosystems are heavily affected by climate. Rapidly changing conditions imply considerable stress on several species and ecosystems, as well as to the most dominant species on the planet. LÄS MER
2. Developing and evaluating dose calculation models for verification of advanced radiotherapy
Sammanfattning : A prerequisite for modern radiotherapy is the ability to accurately determine the absorbed dose (D) that is given to the patient. The subject of this thesis has been to develop and evaluate efficient dose calculation models for high-energy photon beams delivered by linear accelerators. LÄS MER
3. Geometric distortions in MRI based radiotherapy and PET/MRI
Sammanfattning : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). LÄS MER
4. Advancing urban analytics for energy transitions : Data-driven strategic planning for citywide building retrofitting
Sammanfattning : Decarbonisation of the building stock is essential for energy transitions towards climate-neutral cities in Sweden, Europe and globally. Meeting 1. LÄS MER
