1. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. LÄS MER
2. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications
Master-uppsats, KTH/Tillämpad fysikSammanfattning : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. LÄS MER
3. Phase Change Material : Potential for increased fire resistance in concrete
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. LÄS MER
4. Numerical Modelling of a Packed Bed Thermal Energy Storage for Applications in a Carnot Battery : KTH Thesis Report
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. LÄS MER
5. 3d-utskrivet fantom för kontroll av linjär-acceleratorer
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik; Umeå universitet/Centrum för medicinsk teknik och fysik (CMTF)Sammanfattning : Cancer är en sjukdom som var tredje person får som diagnos under en livstid. Stor del av dessa cancerpatienter får behandling med hjälp av strålbehandling. Där strålbehandlingen kan ske med en linjäraccelerator. Linjäracceleratorn producerar elektron eller fotonstrålning i Mega Volt energiområde. LÄS MER
