11. Rotational Diffusion of Cellulose Nanofibrils.
Kandidat-uppsats, KTH/MekanikSammanfattning : Cellulose nanofibrils, CNF, is a technical term for the smallest crystalline constituents of wood. Namely particles of cylindrical shape measuring 20-40 nm in diameter and 1-2 um in length. These fibrils display high ultimate tensile strength and a Young's modulus comparable to Kevlar. LÄS MER
12. Optical sensors for mechanomyography and tissue chromophores
Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : The mechanomyogram (MMG) is a mechanical oscillations observable on the surface of the skin as a muscle contracts. Measurement of the MMG utilizing contact sensors with a weight greater than 6 g has proved to interfere with the measurement. Use of optical displacement sensors without direct contact to the skin would remove this deficiency. LÄS MER
13. Implementing the circularly polarized light method for determining wall thickness of cellulosic fibres
Uppsats för yrkesexamina på avancerad nivå, Bildanalys och människa-datorinteraktionSammanfattning : The wall thickness of pulp fibers plays a major role in the paper industry, but it is currently not possible to measure this property without manual laboratory work. In 2007, researcher Ho Fan Jang patented a technique to automatically measure fiber wall thickness, combining the unique optical properties of pulp fibers with image analysis. LÄS MER
14. Ebbas klänning Uppmätning och analys som källa till information i kombination med historisk undersökning
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : This study focuses on costume as a source of information. By making a case study of an 1880's dress it aims to explore the conservators potential as an investigator and conveyor of the information contained in a costume. Further explanation of this role is made by reference to several statements made by well known textile conservators. LÄS MER
15. Industriell produktion av ljusemitterande vävar
Kandidat-uppsats, Högskolan i Borås/Institutionen TextilhögskolanSammanfattning : Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv. Syftet med examensarbetet var att undersöka om det är möjligt att industriellt producera ljusemitterande vävar med optiska fibrer. Arbetet delades upp i olika delar, både teoretiska och praktiska.
