Effect of osmolarity on the zero-stress state and mechanical properties of aorta.

Some pathological conditions may affect osmolarity, which can impact cell, tissue, and organ volume. The hypothesis of this study is that changes in osmolarity affect the zero-stress state and mechanical properties of the aorta. To test this hypothesis, a segment of mouse abdominal aorta was cannulated in vivo and mechanically distended by perfusion of physiological salt (NaCl) solutions with g...

Ratcheting crystal plasticity modeling in microstructure of magnesium alloy under stress-controlled cyclic tensile loading with non-zero mean stress

Todays, the requirement of lowering the vehicle weight for the reduction of the fuel consumption and emissions, one of the methods considered by designers is to use the ligh magnesium alloy under cylclic loadings. In this article, considering the microstructure of the AZ91D magnesium alloy, its crystalline structure, a model for predicting the ratcheting behavior of this alloy was adapted and v...

Spline surfaces with T-junctions

This paper develops a new way to create smooth piecewise polynomial free-form spline surfaces from quadmeshes that include T-junctions, where surface strips start or terminate. All mesh nodes can be interpreted as control points of geometrically-smooth, piecewise polynomials that we call GT-splines. GT-splines are B-spline-like and cover T-junctions by two or four patches of degree bi-4. They c...

Modeling Nonnegative Data with Clumping at Zero: A Survey

Applications in which data take nonnegative values but have a substantial proportion of values at zero occur in many disciplines. The modeling of such “clumped-at-zero” or “zero-inflated” data is challenging. We survey models that have been proposed. We consider cases in which the response for the non-zero observations is continuous and in which it is discrete. For the continuous and then the d...

Geometry-aware domain decomposition for T-spline-based manifold modeling

This paper presents a new and effective method to construct manifold T-splines of complicated topology/geometry. The fundamental idea of our novel approach is the geometry-aware object segmentation, by which an arbitrarily complicated surface model can be decomposed into a group of disjoint components that comprise branches, handles, and base patches. Such a domain decomposition simplifies obje...
