Multi-resolution isotropic strain limiting

Continuum-based Strain Limiting

We present Continuum-based Strain Limiting (CSL) – a new method for limiting deformations in physically-based cloth simulations. Despite recent developments for nearly inextensible materials, the efficient simulation of general biphasic textiles and their anisotropic behavior remains challenging. Many approaches use soft materials and enforce limits on edge elongations, leading to discretizatio...

Anisotropic Strain Limiting

Many materials exhibit a highly nonlinear elastic behavior, such as textiles or finger flesh. An efficient way of enforcing the nonlinearity of these materials is through strain-limiting constraints, which is often the model of choice in computer graphics. Strain-limiting allows to model highly non-linear stiff materials by eliminating degrees of freedom from the computations and by enforcing a...

Isotropic resolution in Diffusion Weighted Imaging using 3D multi-slab, multi-echo Echo Planar Imaging

INTRODUCTION Diffusion weighted Magnetic Resonance Imaging (DWI) is usually performed using a 2D single shot echo planar imaging technique, because it generates good SNR, short scan times and is immune to phase differences between diffusion-encoded excitations. 2D DWEPI can be acquired with a reasonably high in-plane resolution, especially if parallel imaging is used to reduce the geometric dis...

Classification of Limiting Shapes for Isotropic Curve Flows

with α 6= 0, and initial condition x(p, 0) = x0(p). This produces a family of curves γt = x(S, t). Here κ is the curvature, and n is the outward-pointing unit normal vector. These equations are particularly natural in that they are isotropic (equivariant under rotations in the plane) and homogeneous (equivariant under dilation of space, if time is also scaled accordingly). The main aim of this ...
