This paper presents a mathematical model of biological structures in relation to coronary arteries with atherosclerosis. A set of equations has been derived to compute blood flow through these transport vessels with variable axial and radial geometries. Three-dimensional reconstructions of diseased arteries from cadavers have shown that atherosclerotic(More)
A mathematical model of blood flow through a stenosed artery is presented. The arterial wall and stenosis are assumed to be viscoelastic and axisymmetric. The constitutive equations are solved using pertubation methods and these solutions are compared with the predictions of models that assume Poisseuille and turbulent flow through a rigid stenosed tube.(More)
Two experiments were conducted examining the effectiveness of visualizations of unstructured texts that consisted of transcriptions of unrehearsed dialogue and emails respectively. In general, the findings of both studies were similar to those of Butavicius and Lee’s (2007) experiment which used highly structured news articles; namely, an advantage in(More)
Two experiments were conducted examining the effectiveness of visualizations of unstructured texts. The first experiment presented transcriptions of unrehearsed dialog and the second used emails. Both experiments showed an advantage in overall performance for semantically structured two-dimensional (2D) spatialized layouts, such as multidimensional scaling(More)
