A phase-field method for modeling cracks with frictional contact
, 2019 We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field method has two attractive features: (1) it can represent arbitrary crack ...

Automatic normal orientation in point clouds of building interiors
, 2019 Orienting surface normals correctly and consistently is a fundamental problem in geometry processing. Applications such as visualization, feature detection, and geometry reconstruction often rely on the availability of correctly oriented normals.

Learners’ algebraic and geometric connections when solving Euclidean geometry riders
PythagorasIn this article, we explored Grade 11 learners’ algebraic and geometric connections when solving Euclidean geometry riders. A qualitative interpretive case study design was followed.

Painlev\'{e}-Gullstrand-type coordinates for the five-dimensional Myers-Perry black hole [PDF]
, 2013 The Painleve-Gullstrand coordinates provide a convenient framework for presenting the Schwarzschild geometry because of their flat constant-time hypersurfaces, and the fact that they are free of coordinate singularities outside r=0.

Stress-Energy Tensor Induced by Bulk Dirac Spinor in Randall-Sundrum Model
, 2010 Motivated by the possible extension into a supersymmetric Randall-Sundrum (RS) model, we investigate the properties of the vacuum expectation value (VEV) of the stress-energy tensor for a quantized bulk Dirac spinor field in the RS geometry and compare ...

Deformation of grain boundaries in polar ice
, 2004 The ice microstructure (grain boundaries) is a key feature used to study ice evolution and to investigate past climatic changes. We studied a deep ice core, in Dome Concordia, Antarctica, which records past mechanical deformations. We measured a "texture

, 2002 Noncommutative geometry governs the physics of quantum Hall (QH) effects. We introduce the Weyl ordering of the second quantized density operator to explore the dynamics of electrons in the lowest Landau level. We analyze QH systems made of $N$-component

Revista LinguísticaIn the framework of the Agree operation of Chomsky (2000, 2001) and the feature geometry of Harley and Ritter (2002), this paper develops the hypothesis that the impossibility of combining certain clitics (Person Case Constraint (PCC)) is a consequence ...

Geometry dependent microstructures: bug or feature?
Procedia CIRP, 2018 Abstract Selective laser melting (SLM) promises not only geometric freedom, but is envisioned to allow tailored microstructures as well. While the possibility to be able to build chosen microstructures in certain areas of a part is often seen as a feature, the local change in microstructure due to a changing geometry is just as often seen as a bug ...
