16. Railway tread braking temperatures - Numerical simulation and experimental studies
Sammanfattning : Tread (block) braking is still one of the most common braking systems on railway vehicles. The action is carried out by pressing brake blocks against the tread of a wheel, which is also in rolling contact with the rail. LÄS MER
17. Risk, Relative Standing and Property Rights: Rural Household Decision-Making in China
Sammanfattning : Paper 1 examines the concern for relative standing among rural households in China. We used a survey-experimental method to measure to what extent poor Chinese farmers care about their relative income and found that the respondents cared to a high degree. LÄS MER
18. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis
Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER
19. Inference on Dark Matter in Effective Field Theories : From XENON1T towards XENONnT: Chiral effective field theory analysis of nuclear recoils, single electrons and uncommon background modelling
Sammanfattning : Cosmological and astronomical observations show that most of the matter in the Universe is dark. This dissertation provides an overview of the dark matter evidence, and focuses on the particle dark matter hypothesis, describing possible particle candidates, concentrating on the Weakly Interactive Massive Particles (WIMPs).

20. Experimental investigation of the flow field in an aggressive intermediate turbine duct
Sammanfattning : Intermediate turbine ducts are used for connecting thehigh-pressure turbine to the low-pressure turbine in turbofan engines. In order to meet the demands for more efficient and environmentally friendly jet engines, future intermediate turbine ducts need to have larger radial off-sets without increasing their length. LÄS MER
