1. Lower Bounds and Trade-offs in Proof Complexity
Sammanfattning : Propositional proof complexity is a field in theoretical computer science that analyses the resources needed to prove statements. In this thesis, we are concerned about the length of proofs and trade-offs between different resources, such as length and space. LÄS MER
2. Towards Sustainable Bioenergy - Governance, Resource potentials and Trade-offs
Sammanfattning : The global energy system needs to be transformed from fossil dependent to renewable, to cope with the challenges of resource scarcity and climate change. Bioenergy can play an important role in this transformation, but land is scarce, and uncontrolled bioenergy expansion could have unacceptable consequences. LÄS MER
3. Defence on Demand : A physiological perspective on phenotypic plasticity in anti-predator traits
Sammanfattning : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. LÄS MER
4. Device-to-Device Communications for Future Cellular Networks : Challenges, Trade-Offs, and Coexistence
Sammanfattning : The steep growth in mobile data traffic has gained a lot of attention in recent years. With current infrastructure deployments and radio resources, operators will not be able to cope with the upcoming demands. LÄS MER
5. Physiological trade-offs in reproduction and condition dependence of a secondary sexual trait
Sammanfattning : This thesis examines parental condition, how it is traded off against reproduction and how it is displayed in a secondary sexual trait. The studies were performed on nest-box breeding collared flycatchers Ficedula albicollis on the island of Gotland, in the Baltic Sea. LÄS MER
