16. Internal frost damage in concrete - experimental studies of destruction mechanisms
Abstract : The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.

17. A Methodology to Control the Microstructure of Plasma Sprayed Coatings
Abstract : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.

18. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth
Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

19. Generation and Applications of Short-Pulse X-ray Radiation
Abstract : This thesis summarizes work using hard X-ray radiation on nanosecond and picosecond timescales. The focus is on the experimental part including detailed descriptions of setups for laser pumped - X-ray probe experiments. X-ray diffraction is sensitive to structural properties on the length scale of chemical bonds. READ MORE

20. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments
Abstract : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. READ MORE
