  2. 6. Phosphine ligands with triamine functionality - preparation and application in catalysis

    Author : Magnus Karlsson; Enheten för fysikalisk och teoretisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; water soluble; palladium; amphiphilic; rhodium; Oorganisk kemi;

    Abstract : Incorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their complexes between water and an organic solvent is controlled by the pH of the aqueous phase. READ MORE

  4. 7. Static and Dynamic Modelling of the Drying Section of a Paper Machine

    Author : Magnus Karlsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pappers- och massateknik; Modelling; Wood; Paper; Multi-Cylinder; Simulation; Control; Steam; Air; Dew Point; Moisture Gradients; pulp and paper technology; Pressure Gradients;

    Abstract : The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. READ MORE

  5. 8. The liberalisation of telecommunications in Sweden : Technology and regime change from the 1960s to 1993

    Author : Magnus Karlsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; telecommunications; liberalisation; deregulation; international regimes; national regimes; sociotechnical systems; large technical systems; technological convergence; Sweden; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This study describes the liberalisation of telecommunications in Sweden and analyses the role of technology in this process. The stable and largely successful traditional monopoly regime was challenged in the 1980s by the development of new technologies and the general trend towards market orientation and competition.

  6. 9. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill

    Author : Magnus Karlsson; Lars J. Nilsson; Linköpings universitet; []
    Keywords : MIND; Industrial energy systems; Investment; pulp and paper; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. READ MORE

  7. 10. Data Prefetching Techniques Targeting Single and a Network of Processing Nodes

    Author : Magnus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis considers two approaches to the design of high-performance computers. In a single processing node with one processor, performance is degraded when requested data is not found in the cache, because it has to be retrieved from slower memory. READ MORE
