16. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites
Sammanfattning : 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. LÄS MER
17. Bright and strain-tunable semiconductor quantum dot devices
Sammanfattning : 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. LÄS MER
18. Numerical predictions and measurement of non-isothermal airflows : evaluation of buoyant wall jets and airflow through large openings
Sammanfattning : 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. LÄS MER
19. Fracture behaviour and related microstructures of tool steels parted-off at high rates of strain
Sammanfattning : 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. LÄS MER
20. Methods for measurement of vocal fold vibration and viscoelasticity
Sammanfattning : 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. LÄS MER
