1. Residual Stresses and Fatigue of Shot Peened Cast Iron
Sammanfattning : The complex geometry of cylinder head in heavy-duty diesel engine makes grey cast iron or compact graphite iron a perfect material choice due to its castability, thermal conductivity and damping capacity. To increase the efficiency of the engine, the fatigue property of the material needs to be improved. LÄS MER
2. The Influence of Residual Stresses on Fatigue Behaviour of Medium Carbon Microalloyed Steel
Sammanfattning : Subjected to the dynamic loading, truck components are exposed to fatigue loading. Hence the methods to improve the fatigue properties of the components are widely employed by manufacturers. One of the well known methods in this field is shot peening. LÄS MER
3. The Influence of Residual Stresses on Constant and Variable Amplitude Fatigue Behaviour of Steel
Sammanfattning : Subjected to dynamic loading, truck components are exposed to variable amplitude fatigue. The fatigue life of components is to a large degree controlled by the behaviour of the surface zones. LÄS MER
4. Noise Properties of the Single Electron Transistor
Sammanfattning : The Single Electron Transistor (SET) is a sensitive electrometer with a charge sensitivityultimately limited by noise. In this thesis we present measurements of noiseproperties and charge sensitivity of the radio-frequency Single Electron Transistor. LÄS MER
5. Fluctuations and nonequilibrium thermodynamics in electronic nanosystems
Sammanfattning : In the last decades thermodynamics has seen a resurgence because of the interesting phenomena that happen in small-scale systems. Indeed, in nanoscale devices, quantum effects and fluctuations cannot generally be neglected and influence both the transport and their thermodynamic performance. LÄS MER
