  1. 1. Adaptive signal processing of surface electromyogram signals

    Författare :Nils Östlund; Stefan Karlsson; Jun Yu; Björn Gerdle; Leif Sörnmo; Umeå universitet; []
    Nyckelord :Signalbehandling; electromyography; signal processing; Signalbehandling; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : Electromyography is the study of muscle function through the electrical signals from the muscles. In surface electromyography the electrical signal is detected on the skin. The signal arises from ion exchanges across the muscle fibres’ membranes. LÄS MER

  3. 2. AssistancePlus : 3D-mediated Advice-giving on Pharmaceutical Products

    Författare :Martin Östlund; Nils Dahlbäck; Mattias Arvola; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D; pharmaceutical advice-giving; remote instruction; 3D-mediated communication; video communication; co-browsing; web3D; common ground; Information technology; Informationsteknik;

    Sammanfattning : In the use of medication and pharmaceutical products, non‐compliance is a major problem. One thing we can do something about is making sure consumers have the information they need. This thesis investigates how remote communication technology can be used to improve the availability for expressive advice‐giving services. LÄS MER

  4. 3. Contributions to quantitative dynamic contrast-enhanced MRI

    Författare :Anders Garpebring; Mikael Karlsson; Ronnie Wirestam; Nils Östlund; Jón Hauksson; Steven Sourbron; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic contrast-enhanced MRI; quantitative imaging; parameter estimation; uncertainty estimation; arterial input function; radiofysik; radiation physics;

    Sammanfattning : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. LÄS MER

  5. 4. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard

    Författare :Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Inhomogeneities; In-plane properties; Tension; Compression; Shear properties; Delamination; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. LÄS MER

  7. 5. Pulp strength enhancement by oxygen delignification

    Författare :Claudia Esteves; Elisabet Brännvall; Olena Sevastyanova; Sören Östlund; Christine Chirat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber charge; morphology; oxygen delignification; swellability; tensile properties; dragegenskaper; fiberladdningar; morfologi; svällningsförmåga; syrgasdelignifiering; Chemical Engineering; Kemiteknik;

    Sammanfattning : Oxygen delignification is widely used in the pulp and paper industry as a part of delignification process between the kraft cook and bleaching. However, its potential has not been fully utilized. LÄS MER
