Continuum model for mesh crystallization

Physical Review E, 2005
The front propagation of a single crystallizing domain has been well studied for more than a century. In many important crystallization processes, however, multiple domains grow simultaneously, resulting in a multicrystalline, meshlike aggregate. This is the typical case for organic compounds, including polymers and alkanes. We have studied such growth

Model Transduction for Triangle Meshes

Journal of Computer Science and Technology, 2010
This paper proposes a novel method, called model transduction, to directly transfer pose between different meshes, without the need of building the skeleton configurations for meshes. Different from previous retargetting methods, such as deformation transfer, model transduction does not require a reference source mesh to obtain the source deformation ...

Molecular Surface Modeling and Meshing

Engineering with Computers, 2002
An increasingly important part of quantum chemistry is devoted to molecular surfaces. To model such a surface, each constituting atom is idealized by a simple sphere. Surface mesh generation techniques are then used either for visualization or for simulation, where mesh quality has a strong influence on solution accuracy.

Efficient Adaptive Meshing of Parametric Models

Journal of Computing and Information Science in Engineering, 2001
Parametric modeling is becoming the representation of choice for most modern solid modelers. However, when generating the finite-element mesh of the model for simulation and analysis, most meshing tools ignore the parametric information and use only the boundary representation of the model for meshing.

Markov Mesh Models

Computer Graphics and Image Processing, 1980
Publisher Summary This chapter reviews the Markov Mesh models as originally given in the works of Abend, Harley, and Kanal. It also presents some inputs on some related references and developments of Markov Random Fields (MRF) models. The Markov Mesh models presented in the works of these authors sought to incorporate spatial dependence in reducing ...

Simulation of PRAM models on meshes

1994
We analyze the complexity of simulating a PRAM (parallel random access machine) on a mesh structured distributed memory machine. By utilizing suitable algorithms for randomized hashing, routing in a mesh, and sorting in a mesh, we prove that simulation of a PRAM on \(\sqrt N \times \sqrt N (or \sqrt[3]{N} \times \sqrt[3]{N} \times \sqrt[3]{N})\) mesh ...

Mesh Segmentation and Model Extraction

2012
High precision laser scanners deliver virtual surfaces of industrial objects whose accuracy must be evaluated. But this requires the automatic detection of reliable components such as facets, cylindric and spherical parts, etc. The method described here finds automatically parts in the surface to which geometric primitives can be fitted.

Gaussian Model for 3D Mesh Steganography

IEEE Signal Processing Letters, 2021
Currently, mainstream 3D steganographic algorithms embed data through geometric modifications. To enhance the anti-steganalysis ability of such algorithms, we propose an additive Gaussian noise model for 3D mesh steganography. Our work starts with a theoretical analysis for correlations of vertex coordinate components. Based on this analysis, the whole

The comparison of heavyweight mesh and lightweight mesh in an incisional animal model

Hernia, 2010
An incisional hernia may occur through the incision area following a surgical operation, through the trocar opening and even through drainage exit points. Various synthetic surgical meshes have recently been used for the surgical repair of incisional hernias.

A SEPARATION BETWEEN RECONFIGURABLE MESH MODELS

Parallel Processing Letters, 1995
We prove a separation between two models of the reconfigurable mesh (rmesh), the cross-over model and the non-cross-over model. Specifically, for any constant k ≥ 1, we show that in the non-cross-over model, a k × n rmesh requires Ω( log n) time to compute the parity of n bits stored one per column, while in the cross-over model, when k ≥ 3, a k × n ...
