  2. 16. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

    Author : Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

    Abstract : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. READ MORE

  4. 17. Bright and strain-tunable semiconductor quantum dot devices

    Author : Thomas Lettner; Val Zwiller; Klaus D. Jöns; Oliver Benson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single–photons; entanglement; strain–tunable; kvantprickar; singelfotoner; sammanflätning; töjnings-justerbar; Optik och fotonik; Optics and Photonics;

    Abstract : Optically active semiconductor quantum dots have proven to be excellent single- and entangled-photon sources, with applications in quantum optics and quantum photonics. These sources are considered crucial in the development of future photonic quantum technology, such as quantum communication, quantum computation and quantum metrology. READ MORE

  5. 18. Numerical predictions and measurement of non-isothermal airflows : evaluation of buoyant wall jets and airflow through large openings

    Author : Tobias Törnström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : How can we attain a good indoor climate and at the same time reduce energy consumption? These issues are of particular interest in countries with cold climates, where the need for heating is large. It is important to design a HV AC (Heating, Ventilation and Air Conditioning) system that achieves a desirable indoor climate, where discomfort due to draft and thermal discomfort is avoided.

  6. 19. Fracture behaviour and related microstructures of tool steels parted-off at high rates of strain

    Author : Kristina Ryttberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-velocity parting-off; adiabatic cutting; high strain-rate deformation; TEM; steel; adiabatic shear band;

    Abstract : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off, or adiabatic cutting, has shown to result in very low material waste as well as narrow dimensional tolerances of parted-off samples. READ MORE

  7. 20. Methods for measurement of vocal fold vibration and viscoelasticity

    Author : Hans Larsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : High-speed video imaging; kymography; acoustic analysis; vocal fold vibration; glottal edge; glottal area; laser; mucosal wave; triangulation; vocal fold; vocal fold length; vocal fold width; vocal fold strain; non-invasive; vocal fold scarring; air pulse stimulation;

    Abstract : The overall aim of the thesis was to develop new methods for analysis of vocal fold vibrations and viscoelasticity and to test them in human subjects. In Study I the onset of vibration and irregular vocal fold vibration was examined with laryngoscopy using a high-speed camera at a frame rate of about 2000 images/sec. READ MORE
