11. Modeling, Model Validation and Uncertainty Identification for Power System Analysis
Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

12. Assessment of everyday functioning for adults with hearing loss : Development of Hearing and Functioning in Everyday life Questionnaire (HFEQ)
Sammanfattning : Aim: The overall aim of the current thesis was to develop a self-assessmentinstrument with a focus on everyday functioning for adults with hearingloss and to investigate its psychometric properties.Methods: Three different methods were applied in the current studies; a scoping review (Study I), two quantitative studies using two different datacollection processes (Study II and IV) and a qualitative study, including anitem-generation workshop and cognitive group interviews (Study III).

13. Solar receiver development for gas-turbine based solar dish systems
Sammanfattning : Small-scale concentrating solar power plants such as micro gas-turbine based solar dish systems have the potential to harness solar energy in an effective way and supply electricity to customers in remote areas. In such systems, the solar receiver transfers the power of concentrated solar radiation to the working fluid of the power conversion cycle. LÄS MER
14. Concepts for hot sheet metal forming of titanium alloys
Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER
15. Multi-objective CFD-based design method for axial compressors
Sammanfattning : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. LÄS MER
