2. Thin Film Plate Acoustic Resonators for Frequency Control and Sensing Applications
Sammanfattning : The recent development of the commercially viable thin film electro-acoustic technology has triggered a growing interest in the research of plate guided wave or Lamb wave components owing to their unique characteristics. In the present thesis i) an experimental study of the thin film plate resonators (FPAR) performance operating on the lowest symmetrical Lamb wave (S0) propagating in highly textured AlN membranes versus a variety of design parameters has been performed.

3. Recovery of Scandium using Antisolvent Crystallization in the Valorization of Scandium-containing Waste Streams
Sammanfattning : Scandium is widely dispersed in the earth’s crust and is rarely concentrated in ores, and a viable option to guarantee a secure supply of scandium is to recover the metal from waste streams of other mining and metallurgical facilities. The valorization of such streams to recover metals of value is a prerequisite to alleviate the global shortages of scandium and other rare earth elements. LÄS MER
4. Effective use of X rays in diagnostic radiology : Guidance for the optimisation of image quality and absorbed dose in the patient by use of a Monte Carlo computational model of the imaging chain
Sammanfattning : The primary objective of this thesis is to give guidance for the reduction of absorbed dose in the patient and the improvement of image quality by the optimisation of the various parameters which control the performance of the radiological imaging system. The optimisation means that image quality (contrast in screen-film imaging and signal-to-noise ratio in digital imaging) is kept constant and combinations of operating parameters which yields the lowest mean absorbed dose in the patient is determined.

5. Modelling and simulation of metal working processes
Sammanfattning : This thesis consists of seven papers. All deal with the modelling and simulation of metal working processes. The aim of the research has been to increase understanding of this kind of process by studying specific problems and making models. The processes that have been studied are hot rolling, bending and ironing. LÄS MER
