Shape-Up: Shaping Discrete Geometry with Projections

Mark Pauly, Sofien Bouaziz, Yuliy Gennadievich Schwartzburg, Mario Moacir Deuss

We introduce a uniﬁed optimization framework for geometry processing based on shape constraints. These constraints preserve or prescribe the shape of subsets of the points of a geometric data set, such as polygons, one-ring cells, volume elements, or featu ...

Geometries and vibrational frequencies of small radicals: Performance of Coupled Cluster and more approximate methods

Jeremy Samuel Arey, Peter Rudolf Tentscher

We generated a new set of reference geometries of small radicals using experimental equilibrium structures, as well as a benchmark-quality coupled cluster additivity scheme including up to quadruples excitations (CCSDTQ). Using these geometries and a set o ...

Drawing with Nanostencils on Flexible Substrates

Jürgen Brugger, Andreea Veronica Savu, Oliver Peric

Nanostencils are used in dynamic mode to pattern on top of flexible substrates. As the stencil is moving during the material evaporation, the obtained structures are the convolution between the stencil trajectory and the apertures’ geometry. Variable-thick ...

Open-loop control of compressible afterbody flows using adjoint methods

Philippe Meliga

The flow past an axisymmetric body is generically unstable to a steady and a time-periodic global instability, the latter being thought to lead the low-frequency unsteadiness of the wake even at larger Reynolds numbers. The present paper examines how the g ...

Gravity-driven slug motion in capillary tubes

Dani Or, Ivan Lunati

The velocity of a liquid slug falling in a capillary tube is lower than predicted for Poiseuille flow due to presence of menisci, whose shapes are determined by the complex interplay of capillary, viscous, and gravitational forces. Due to the presence of m ...

FEM-based prediction of workpiece transient temperature distribution and deformations during milling

Paul Xirouchakis, Jitender Kumar Rai

In high-speed dry milling of thin-walled parts, the cutter-workpiece temperature rises asymptotically with cutting speed, causing excessive cutter tooth wear and workpiece thermal expansion, which in turn reduces the cutter life and produces dimensional an ...

Laplacian Operator, Diffusion Flow and Active Contour on non-Euclidean Images

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Iva Bogdanova Vandergheynst

We propose here some basic approaches to direct processing of the

-images as we take into consideration the geometry of each one. Obviously, the geometry of each of these images is a consequence of the geometry of the sensor's mirror used. This tech ...

Flow Investigation in a Francis Draft Tube : the Flindt Project

François Avellan

The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...

Modélisation et simulation bidimensionnelles de la croissance des polycristaux

In this article it is shown that Laguerre partitions of the unit torus yield faithful global representations of the geometry of ceramic polycrytals at the microscopic level. On this basis, a simulation model has been developed and tested reproducing some o ...
