11. Female reproductive strategies and sexual conflicts in a polygynous mating system
Sammanfattning : In this thesis, I have investigated conflicts of interest in the facultatively polygynous European starling (Sturnus vulgaris) with a focus on female reproductive strategies. The extent to which males provided parental care was a key issue in understanding the mating system of the starling. LÄS MER
12. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation
Sammanfattning : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. LÄS MER
13. Non-geological hydrogen storage for fossil-free steelmaking
Sammanfattning : In the last half-century, global steel use has increased more than threefold and further growth is expected, particularly in developing economies. However, steelmaking is currently responsible for 7% of the global net carbon dioxide (CO2) emissions, and any substantial further optimization of existing processes that utilize fossil fuels for iron ore reduction is infeasible.

15. Design Automation for Multidisciplinary Optimization : A High Level CAD Template Approach
Sammanfattning : In the design of complex engineering products it is essential to handle cross-couplings and synergies between subsystems. An emerging technique, which has the potential to considerably improve the design process, is multidisciplinary design optimization (MDO).MDO requires a concurrent and parametric design framework.
