11. Illness perception and fatigue after myocardial infarction
Sammanfattning : Treatment of myocardial infarction (MI) has undergone major advances in recent years, including reductions in mortality and hospital stays. To optimize patients’ recovery, secondary preventive strategies are important. However, many patients fail to attend to such programmes. LÄS MER
12. No limits : the 20th century discourse of economic growth
Sammanfattning : The breakthrough of the concept of economic growth in economics marks a paradigm shift in thinking about the economy and its place in 'reality.' This thesis analyzes the 20th century discourse of economic growth, focusing its unlimited connotations. The thesis consists of four case studies, two introductory parts and a concluding discussion.

13. Topological Phase Transitions in Magnetic Nanostructures of Dirac Materials
Sammanfattning : Over the past two decades, the discovery of topological Dirac materials, such as topological insulators and semimetals, has defined a new paradigm in condensed matter physics and established new platforms for realizing spin electronic devices and quantum computing. The novel quantum properties of these materials, which are mainly due to the presence of strong spin-orbit coupling, are invariant under topological transformations, making them more resilient to structural disorder, electromagnetic and thermal fluctuations in comparison to the conventional silicon-based materials.

14. Modeling and Stability Analysis of Rate and Power Control Systems in Wireless Communication Networks
Sammanfattning : Wireless data traffic in cellular networks is currently undergoing a strong global expansion and the demand for high and reliable data throughput increases. Capacity is, however, a limited resource, and in radio resource management a trade-off has to be made between the congestion level, related to cell coverage and interference levels, and the Quality of Service (QoS) or data rates of the users.

15. First-principles description of planar faults in metals and alloys
Sammanfattning : Phase interface and stacking fault are two common planar defects in metallic materials. In the present thesis, the interfacial energy and the generalized stacking fault energy of random alloys are investigated using density functional theory formulated within the exact muffin-tin orbitals (EMTO) method in combination with the coherent-potential approximation (CPA).
