This paper describes a new approach in modeling of sand surface. The terrain model is based on a triangulated irregular network while existing solutions have been based on a regular grid. Memory consumption is significantly reduced without a regular grid at the expense of more complicated algorithms. Our solution allows deforming terrain by a set of virtual tools and erosion simulation. All the...

Cellular automata (CA) and lattice Boltzmann LB approaches are computational methods that ooer exibility, eeciency and outstanding amenability to parallelism when modeling complex phenomena. In this paper, the CA and LB approach are combined in the same model, in order to describe a system where point-particles are transported in a uid ow. This model is used to simulate the snow transport, eros...

In this study, we present case studies to explore the dynamics of implementation and maintenance of health interventions. We analyze how specific interventions are built and eroded, how the building and erosion mechanisms are interconnected, and why we can see significantly different erosion rates across otherwise similar organizations. We use multiple comparative obesity prevention case studie...

Thermo-deformable plastic films experience an optical birefringence phenomenon when they are subjected to mechanical strain, this phenomenon can be described by color fringes behavior observed in sequences of images acquired through photoelasticity assemblies. This paper proposes a temporary morphological analysis that color fringes experience when the plastic film is deformed. For the image an...

Modeling particle based heterogeneous materials using statistical volume elements (SVE) for predicting its mechanical behavior can be tedious when the particles are densely packed or elongated. Positioning without creating overlaps and avoiding meshing problems two obstacles frequently mentioned. To counter these obstacles, a new modeling methodology on multibody dynamics (MBD) an erosion-based...

Chemical-mechanical planarization (CMP) is an enabling technique to achieve uniformity of dielectric and conductor height in BEOL manufacturing processes. Dummy fill insertion improves the uniformity of metal feature density and enhances the planarization that can be obtained by CMP, but can also change the coupling and total capacitance of interconnects [1], [2]. Additionally, dishing and eros...

A mathematical and numerical model of the joint dynamics surface water traction sediment is built, which takes into account nonlinear fluid bottom deformation. The waters described by equations Saint-Venant, taking spatially inhomogeneous distribution terrain. transport loads Exner equation, generalized to case a parameters underlying surface. For integration Saint-Venant equations, stable well...
