1. Bayesian Inference for Microwave Diagnostics at Joint European Torus
Sammanfattning : The major goal of this thesis is to perform Bayesian inference jointly for electron kinetic profiles, a toroidal magnetic field correction, diagnostic sensitivities, and wall reflection properties given noisy measurements of four microwave diagnostics at the tokamak JET. Besides the measurements, this kind of inference considers prior knowledge, like profile length-scales, to update objectively the information about the physics parameters. LÄS MER
2. Length-scale effects in yielding and damage development in polymer materials
Sammanfattning : .... LÄS MER
3. Modeling framework for ageing of low alloy steel
Sammanfattning : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. LÄS MER
4. Micro-mechanical mechanisms for deformation in polymer-material structures
Sammanfattning : In this thesis, the focus has been on micro-mechanical mechanisms in polymer-based materials and structures. The first part of the thesis treats length-scale effects on polymer materials. Experiments have showed that the smaller the specimen, the stronger is the material. LÄS MER
5. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging
Sammanfattning : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.
