6. Climate and dengue fever : early warning based on temperature and rainfall
Sammanfattning : Background: Dengue is a viral infectious disease that is transmitted by mosquitoes. The disease causes a significant health burden in tropical countries, and has been a public health burden in Singapore for several decades. Severe complications such as hemorrhage can develop and lead to fatal outcomes. LÄS MER
7. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature
Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. LÄS MER
8. High temperature galling : influencing parameters and mechanisms
Sammanfattning : Damage of forming tools at elevated temperatures is a major problem in metal forming processes such as hot stamping. Of special importance is the occurrence of adhesion and gross material transfer from the work-piece to the tool surface, a phenomenon known as galling. LÄS MER
9. On high temperature oxidation resistance : Towards the materials genome of high temperature alloys
Sammanfattning : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis. LÄS MER
10. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces
Sammanfattning : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. LÄS MER
