  1. 1. Electrochromic Polymer Devices: Active-Matrix Displays and Switchable Polarizers

    Författare :Peter Andersson; Magnus Berggren; Nathaniel Robinson; Per Bröms; Linköpings universitet; []
    Nyckelord :conjugated polymer; PEDOT:PSS; active-matrix; displays; polarizer; polyaniline; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Major efforts have been spent during recent years in worldwide attempts to achieve an electronic paper technology; the common name for novel flexible displays utilizing substrates such as paper, plastics or thin metal sheets. Various kinds of technology are available that potentially will be used for an electronic paper, which differs from each other mainly with respect to the choice of active materials, substrates and manufacturing techniques.

    Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER

  4. 3. Matrix metalloproteinases in Helicobacter inducedgastritis

    Författare :Philip Bergin; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; Helicobacter felis; Matrix metalloproteinase; macrophage; ; Gastritis;

    Sammanfattning : Helicobacter pylori infects the stomach and areas of gastric metaplasia in the duodenum. Theinfection leads to peptic ulcers or gastric cancers in 10-20% of infected individuals, while themajority are more or less asymptomatic. However, active chronic gastritis develops in all infectedindividuals, often in association with atrophic gastritis. LÄS MER

  5. 4. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    Författare :Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER
