1. Asymptotics of the Scenery Flow and Properties of the Fourier Dimension
Sammanfattning : This thesis is about the scenery flow and the Fourier dimension.The scenery flow is a semiflow on the space of Borel probability measures on the interval [-1, 1] that have the origin in their support. The flow acts on such a measure by enlarging it, restricting it back to [-1, 1] and renormalising it to a probability measure. LÄS MER
2. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization
Sammanfattning : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. LÄS MER
3. Flow dynamics of exhaust aftertreatment systems
Sammanfattning : .... LÄS MER
4. X-ray characterization of PaPheOH, a bacterial phenylalanine hydroxylase
Sammanfattning : Many human diseases are associated with the malfunction of enzymes in the aromatic amino acid hydroxylase family, e.g. phenylketonuria (PKU), hyperphenylalaninemia (HPA), schizophrenia and Parkinson's disease. LÄS MER
5. Epitaxial growth, structure, and thermoelectric properties of CaMn- and V-based oxides
Sammanfattning : This thesis is focused on physical vapor deposition, epitaxy, and structural characterization of CaMnO3 and VO2. Environmentally friendly and abundant materials are important for energy savings in applications, e.g., thermoelectrics for waste-heat recycling and thermochromic materials for passive indoor-temperature regulation.
