  2. 1. Complement Activation Triggered by Biomaterial Surfaces : Mechanisms and Regulation

    Author : Jonas Andersson; Bo Nilsson; Hans Elwing; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Biomaterials; Biocompatibility; Blood; Complement; Immunologi; Immunology; Immunologi; klinisk immunologi; Clinical Immunology;

    Abstract : Today there are a vast number of medical devices in temporary or permanent contact with human tissues. Blood-biomaterial contact is known to trigger the complement system and results in generation of fluid phase anaphylatoxins C3a and C5a, and surface-bound C3b and iC3b. READ MORE

  4. 2. Risk-based ship security analysis : a decision-support approach

    Author : Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Rolf Skjong; Försvarshögskolan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; survivability; uncertainty analysis; militära fartyg; sjöröveri; riskanalys; sjöfartsskydd; överlevnadsförmåga; Försvarssystem; Military Technology;

    Abstract : The protection of shipping does not come without hazards and threats for military forces, individual civilian ship operators and crews. With particular focus on security threats, this thesis is about how to prepare for such operations without introducing unnecessary risks, i.e., supporting conscious risk-taking related to ship security.

  5. 3. TiC-based nanocomposite coatings as electrical contacts

    Author : Jonas Lauridsen; Lars Hultman; Per Eklund; Hans Högberg; Michael Stüber; Linköpings universitet; []
    Keywords : ;

    Abstract : This Thesis concerns the advanced surface engineering of novel TiC-based nanocomposite and AgI electrical contact materials. The objective is to make industrially applicable coatings that are electrically conductive and wear-resistant, and have a low coefficient of friction. READ MORE

  6. 4. Risk-based ship security analysis – an approach based on civilian and military methods

    Author : Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Jakob Kuttenkeuler; Försvarshögskolan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; Försvarssystem; Military Technology;

    Abstract : The demands on maritime operations today are increasingly higher in terms of control, efficiency and cost. The margins for accidents and security incidents are therefore decreasing. In the area of ship safety the regulations, guidelines and methods have a history and culture of systematic research, development and implementation. READ MORE

  7. 5. Modelling and Control Methods with Applications to Mechanical Waves

    Author : Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Abstract : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.
