  1. 1. Thick Concepts in Practice : Normative Aspects of Risk and Safety

    Författare :Niklas Möller; Sven Ove Hansson; Tim Lewens; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; thick concepts; non-naturalism; open question argument; risk analysis; safety; epistemic uncertainty; values in risk assessment; safety engineering; Philosophy subjects; Filosofiämnen;

    Sammanfattning : The thesis aims at analyzing the concepts of risk and safety as well as the class of concepts to which they belong, thick concepts, focusing in particular on the normative aspects involved. Essay I analyzes thick concepts, i.e. concepts such as cruelty and kindness that seem to combine descriptive and evaluative features. LÄS MER

  3. 2. Sublimation Growth of 3C-SiC : From Thick Layers to Bulk Material

    Författare :Valdas Jokubavičius; Mikael Syväjärvi; Rositsa Yakimova; Didier Chaussende; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Silicon carbide (SiC) is a semiconductor material which holds high promises for various device applications. It can be obtained in different crystal structures called polytypes. The most common ones are hexagonal (6H- and 4H-SiC) and cubic (3C-SiC) silicon carbide. LÄS MER

  4. 3. Waveguide-Integrated MEMS Concepts for Tunable Millimeter-Wave Systems

    Författare :Zargham Baghchehsaraei; Joachim Oberhammer; Tauno Vähä-Heikkilä; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents two families of novel waveguide-integrated components based on millimeter-wave microelectromechanical systems (MEMS) for reconfigurable systems. The first group comprises V-band (50–75 GHz) and W-band (75–110 GHz) waveguide switches and switchable irises, and their application as switchable cavity resonators, and tunable bandpass filters implemented by integration of novel MEMS-reconfigurable surfaces into a rectangular waveguide.

  5. 4. New concepts and techniques for quantification and trace analysis by gas chromatography

    Författare :Johan Pettersson; Johan Roerrade; Jan Åke Jönsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; quantitative accuracy; calibration; extenal standards; valume contraction; molar excess volume; Kemi; Chemistry; Kemi;

    Sammanfattning : In the first part of this thesis, strategies for avoiding systematic errors when quantifying the main components in mixtures of solvents has been developed (paper I). It is shown that variations in density caused by variations in sample composition and/or volume contraction need to be taken into account. In this way, quantification can be improved. LÄS MER

  7. 5. Preparation and characterization of nanoporous cellulose fibres and their use in new material concepts

    Författare :Anna Sjöstedt; Lars Wågberg; Akira Isogai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The overall objective of the work in this thesis is to better utilize the non-collapsed structure of the delignified wood-fibre cell wall in the preparation of new types of materials.In order to utilize the fibres in new materials, it is crucial to have a well-defined starting material and to know how it reacts to certain treatments of the fibres.
