Surface mesh generation is one time-consuming step in preparing an unstructured mesh model. However, its parallelisation attracts little attention. In this study, a fine-grained parallel surface meshing algorithm is proposed by taking advantage of the parallelism within the meshing process of a single face. Compared with the scheme which meshes the faces individually in parallel, the proposed a...

We propose to implement the Mesh Design for implementing the Number Field Sieve particularly which will be used to perform the Matrix step to do Matrix Multiplication. Mesh approach is proposed by Daniel Bernstein which brought down the cost of Number Field Sieve by significant factor especially in the matrix step[5]. The computation is done in the mesh-connected array of processors, which util...

objectives: indicators of oral health-related quality of life (ohrqol) in children are widely adopted to evaluate the effects of oral problems. recently, the scale of oral health outcomes for 5-year-old children (soho-5) was developed based on the children’s self-reports. this study aimed to evaluate the validity and reliability of the persian version of the questionnaire in a sample of iranian...

to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...

This paper describes a method for converting existing thesauri and related resources from their native format to RDF(S) and OWL. The method identifies four steps in the conversion process. In each step, decisions have to be taken with respect to the syntax or semantics of the resulting representation. Each step is supported through a number of guidelines. The method is illustrated through conve...

The multi-size-mesh multi-time-step DRP scheme (Tam&Kurbatskii2003) is suited for numerical simulations of multiple-scales aeroacoustics problems. In regions where there are high flow gradients (jet or flow near walls), small grid sizes to resolve small scales are needed. In regions where sound dominates, larger grid sizes for long sound wave lengths may be used to save computation resources. T...

A complete mesh generation or mesh adaptation process usually requires a large number of operators : Delaunay insertion, edge-face-element point insertion, edge collapse, point smoothing, face/edge swaps, etc. Independently of the complexity of the geometry, the more operators are involved in a remeshing process, the less robust the process may become. In addition, deriving a parallel version o...

Recent progress in acquiring shape from range data permits the acquisition of seamless million-polygon meshes from physical models. While dense polygon meshes are an adequate representation for some applications, many users prefer smooth surface representations for reasons of compactness, control, manufacturability, or appearance. In this thesis, we present algorithms and an end-to-end software...

An important part of the Arbitrary Lagrangian-Eulerian method is the rezoning or mesh improvement step after completion of the Lagrangian step where the mesh is deformed according to the flow. A procedure is presented here to optimize the quality of elements in 3D solid meshes by node repositioning. The procedure aims to improve the quality of boundary mesh faces and interior mesh regions while...

We propose to use a moving mesh approach, a popular grid adaption technique in computational mechanics, for fast generating low-stretch mesh parameterizations. Given a triangle mesh approximating a surface, we constrcut an initial parameterization of the mesh and then improve the parameterization gradually. At each improvement step, we optimize the parameterization generated at the previous ste...
