    Sammanfattning : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.

  5. 19. Polarization-Mode Disperion in Optical Fibers: Characterization, Transmission Impairments, and Compensation

    Författare :Henrik Sunnerud; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibers; polarization mode dispersion PMD ; ultra high bit rates; PMD compensation; measurement of distributed PMD; digital signal transmission;

    Sammanfattning : The topic of this thesis is polarization-mode dispersion (PMD) in optical fibers and its impact on high-speed data transmission. The work can be divided into three parts which deal with the major aspects of PMD: characterization, transmission properties and compensation. LÄS MER

  7. 20. Conjugated Polymer-based Conductive Fibers for Smart Textile Applications

    Författare :Tariq Bashir; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-active fibers; poly 3; 4-ethylenedioxythiophene PEDOT ; viscose; polyester; chemical vapor deposition CVD process; electrical characterizations; smart textiles; stretch sensor; Organic Electronics; Smart Textiles; textile yarns; Textiles and Fashion General ; Textil och mode generell ;

    Sammanfattning : Electrically conductive or electro-active fibers are the key components of smart and interactive textiles, which could be used in medical, sports, energy, and military applications in the near future. The functionalization of high-performance textile yarns/fibers with conjugated polymers can produce conductive fibers with better electro-mechanical properties, which is difficult with commonly used spinning techniques.
