  1. 26. Pressure sore etiology - highlighted with optical measurements of the blood flow

    Författare :Annika Jonsson; Ylva Bäcklund; Maria Lindén; Margareta Lindgren; Bertil Hök; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Elektronik;

    Sammanfattning : In line with the quality awareness of good prevention of pressure sores and in treatment of those sores already developed, evaluation of antidecubitus mattresses plays an important role. However, there are shortages in the evaluations performed today, since often interface pressure is the only parameter regarded. LÄS MER

  3. 27. Investigation of Partially Premixed Combustion in an Optical Engine : In-Cylinder Flow and Combustion Characterization

    Författare :Slavey Tanov; Förbränningsmotorer; []
    Nyckelord :PPC; in-cylinder flow structures; Combustion diagnostics; Gasoline; Gasoline-Ethanol; Multiple Injection; Stratification Level;

    Sammanfattning : The diesel engine is one of the most economic power sources and is therefore used in a range of technical solutions. The low fuel consumption combined with high engine performance makes it attractive for transportation vehicles. LÄS MER

  4. 28. Optical manipulation and spectroscopy of single functional globin-containing cells in microfluidic systems

    Författare :Kerstin Ramser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heme-proteins; optical manipulation; resonance Raman spectroscopy; microfluidic systems; single cells; Medical Engineering for Healthcare;

    Sammanfattning : Recent advances in microbiology and biomedicine require development of tools to monitor the response of single cells to environmental stimuli under controlled physiological conditions. In this thesis, I describe how this can be achieved by combining various spectroscopic techniques with optical tweezers and microfluidic systems. LÄS MER

  5. 29. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Författare :Shen Li; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Sammanfattning : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. LÄS MER

  7. 30. Measurements and simulations of thermoplasmonically induced Marangoni flows

    Författare :Pantea Dara; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microbubbles; optical force microscopy; Marangoni flow; thermoplasmonics; microfluidics;

    Sammanfattning : Particle transport in microfluidic environments is often dominated by slow diffusion near interfaces. However, by inducing localized fluid flow, it is possible to actively transport suspended nano-objects in confined spaces. LÄS MER
