  1. 1. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Författare :Magnus Cinthio; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  3. 2. Streets, Spaces and Places : Three Pompeiian Movement Axes Analysed

    Författare :Marina Weilguni; Gullög Nordquist; Henrik Gerding; Henrik Boman; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Pompeii; Space Syntax; urban analysis; public space; Pompeji; Space Syntax; urbanism; offentligt rum; Archaeology; classical; Arkeologi; klassisk; Classical Archaeology and Ancient History; Antikens kultur och samhällsliv;

    Sammanfattning : This study is an urban analysis of Roman Pompeii. It explores the spatial structure of the town just before the eruption of Vesuvius in AD 72, and how public space was used for movement, activity and interaction between people. LÄS MER

  4. 3. Suction dynamics of axial piston pumps

    Författare :Pär-Erik Wiklund; KTH; []
    Nyckelord :;

    Sammanfattning : Computational fluid dynamics (CFD), extensive experimentalstudies and a one-dimensional model based on two pressurereduction coefficients are used in this thesis to analyse thesuction dynamics of an bent axis axial piston pump. Specialattention is given to cavitation since a great deal of problemsare related to this very important phenomenon. LÄS MER

  5. 4. Mass transfer during isothermal drying of a porous solid containing multicomponent liquid mixtures

    Författare :Rafael Gamero; KTH; []
    Nyckelord :internal mass transfer; capillary flow; multicomponent; diffusion; solvent mixtures;

    Sammanfattning : Mass transfer in a porous solid, partially saturated with asingle solvent and multicomponent liquid mixtures, has beenexperimentally and theoretically studied. A porous materialcontaining single liquids and mixtures of organic solvents wasisothermally dried. LÄS MER

  7. 5. Piezoactuators for Miniature Robots

    Författare :Urban Simu; Jean-Marc Breguet; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

    Sammanfattning : Challenges in the realisation of a miniature robot are both to handle the complexity of such a system, and to cope with effects of the actual reduction in physical size of all the parts. In particular, the mechanisms for locomotion have to be analysed. LÄS MER
