21. Watt’s next? On socio-technical transitions towards future electricity system architectures
Sammanfattning : In the effort to fight climate change, the electricity systems around the world are undergoing a transformation towards being based on renewable sources of energy. The criterion of one hundred per cent renewables can, however, be satisfied in several radically different ways, varying from global or continental super grids via local smart-grids to self-sufficient off-grid communities and households of electricity prosumers.

22. Structure formation, phase transitions and drag interactions in multicomponent superconductors and superfluids
Sammanfattning : Superconductivity and superfluidity are some of the most funda-mental and important phenomena of modern physics. However, muchtheoretical work for such systems so far has been restricted to the one-component case. LÄS MER
23. Photonic Devices and Applications based on Intersubband Transitions and Electromagnetically Induced Transparency
Sammanfattning : Although photonic devices have experienced a rapid development lately, there is still room for substantial improvements in performance. From a telecommunications perspective, improvements in speed, size, integration and power consumption are desired. There is also a general interest in photonic devices with new functionalities.

24. Recent transitions in Ethiopian homegarden agroforestry : driving forces and changing gender relations
Sammanfattning : Homegarden agroforestry was a dominant land use practice in Southern Nations, Nationalities and People's Regional State (SNNPRS) Ethiopia until the 1990s. It has been known for its diversity, ecosystem balance and sustainability. LÄS MER
25. Energy innovation and sustainability transitions in China: Building energy efficiency and renewable energy
Sammanfattning : The assumption underlying this thesis is that both technological development and institutional and structural change are required to achieve a more sustainable building sector in China. Earlier literature has taken an approach based on the technological innovation system (TIS) to evaluate and understand the dynamics of technology development and change processes. LÄS MER
