1. Spontaneous online tutoring : Students’ support of their own and other students’ process of inquiry in online text-based tutoring
Sammanfattning : The use of online technologies has made education more accessible. In online education, there are increased expectations for students to be self-directed and take responsibility for their learning. Research has also shown that students can benefit from learning from each other. LÄS MER
2. Turbulence Modelling of Flows Related to Wall-Cooling Applications
Sammanfattning : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.

3. Combining the tactile resonance method and Raman spectroscopy for tissue characterization towards prostate cancer detection
Sammanfattning : Prostate cancer (PCa) is the most common male cancer in Europe and the US, and only lung and colorectal cancer have a higher mortality among European men. In Sweden, PCa is the most common cause of cancer-related death for men. LÄS MER
4. Microstructure and Mechanical Properties of Magnetron Sputtered Refractory Metal Thin Films
Sammanfattning : The design and development of new multifunctional materials that exhibit a combination of high hardness and ductility, as well as a high corrosion resistance and thermal stability, is one of the key challenges in the field of material science. The focus of this thesis is on the development of novel multifunctional magnetron sputtered CrNbTaTiW–C based thin films. LÄS MER
