11. On the deformation behavior and cracking of ductile iron; effect of microstructure
Sammanfattning : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

12. Modeling of dielectrophoresis in micro and nano systems
Sammanfattning : This thesis presents models and simulations of dielectrophoretic separation of micro and nano particles. The fluid dynamics involved and the dielectric properties of water inside single-walled carbon nanotube are studied as well. LÄS MER
13. On the Multi-Scale Nature of Ski-Snow Friction : Field Testing, Characterisation and Modelling of Cross-Country Ski Performance
Sammanfattning : The goal of most endurance sports is to get from point A to B in the shortest time possible. Throughout the course, athletes need to overcome the resistive forces that are present in their specific sport. LÄS MER
14. Numerical study of flow boiling in micro/mini channels
Sammanfattning : Boiling phenomena in micro scale has emerged as an interesting topic due to its complexity and increasing usage in micro electronic and mechanical systems (MEMS). Experimental visualization has discovered five main flow regimes: nucleate boiling, isolated bubbles, confine bubbly flow, elongated bubbly (or slug) flow, and annular flow. LÄS MER
15. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept
Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER
