1. Roll pass design for improved flexibility and quality in wire rod rolling
Abstract : The thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. For analysing the flexibility a computer program has been developed. READ MORE

3. Analysis and Design of Software-Based Optimal PID Controllers
Abstract : A large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller.

4. Modelling and simulation of metal working processes
Abstract : 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. READ MORE

5. SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging
Abstract : The focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. READ MORE
