  1. 16. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

    Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

    Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

  3. 17. Three-Dimensional Modelling of Bond in Reinforced Concrete Theoretical Model, Experiments and Applications

    Författare :Karin Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-dimensional analysis; splitting effects; bond; finite element analysis; reinforced concrete; pull-out tests; non-linear fracture mechanics; frame corners; splicing of reinforcement; cyclic loading;

    Sammanfattning : The bond mechanism between deformed bars and concrete is known to be influenced by multiple parameters, such as the strength of the surrounding structure, the occurrence of splitting cracks in the concrete and the yielding of the reinforcement. However, when reinforced concrete structures are analysed using the finite element method, it is quite common to assume that the bond stress depends solely on the slip. LÄS MER

  4. 18. Depth Map Upscaling for Three-Dimensional Television : The Edge-Weighted Optimization Concept

    Författare :Sebastian Schwarz; Mårten Sjöström; Atanas Gotchev; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3d video; 3DTV; video coding; capture; distribution; EWOC; depth map upscaling; time-of-flight;

    Sammanfattning : With the recent comeback of three-dimensional (3D) movies to the cinemas, there have been increasing efforts to spread the commercial success of 3D to new markets. The possibility of a 3D experience at home, such as three-dimensional television (3DTV), has generated a great deal of interest within the research and standardization community. LÄS MER
