This paper deals with the biomechanical analyse of the human eye with a complex numerical model. We present our three dimensional finite element model including the built-up parts, applied material and geometric properties. Hereupon we describe the subjects which we want to investigate with this 3D model, such as accommodation, presbyopia and so on. We highlight the accommodation problem of the...

In this paper we present the 2D parametric freehand sketch component of an experimental prototype called GEGROSS (GEsture & Geometric ReconstructiOn based Sketch System). The module implements a gesture alphabet and a calligraphic interface to manage geometric constraints found in 2D sections, that are later used to perform modeling operations. We use different elements to implement this module...

A computer modeling approach for constructing a three-dimensional microsphere-packed bone graft structure is presented. The modeling approach consists of both geometric and CAD-based computer modeling. The geometric model uses two extreme microsphere packing models (minimum-density packing and maximum-density packing) and a statistical packing model to determine the number of microspheres packe...

Database normalization is a standard technique to ensure data integrity. Explicitly specified 3D topology as well ensures geometric consistency. This article explains a stepwise reduction of redundancy in the 3D data model. Whereas the topological normalization is well discussed in literature the geometric normalization is a subject to recent research. This approach of data normalization is mot...

A new information-geometric approach to chaotic dynamics on curved statistical manifolds based on Entropic Dynamics (ED) [1] is proposed. It is shown that the hyperbolicity of a non-maximally symmetric 6N-dimensional statistical manifold Ms underlying an ED Gaussian model describing an arbitrary system of 3N non-interacting degrees of freedom leads to linear information-geometric entropy growth...

a r t i c l e i n f o Keywords: Dimensional metrology Interoperability Standard development STEP DMIS Dimensional metrology is an important part of any manufacturing system. It consists of distinct components and requires a large, diverse, and interconnected knowledge base. How to pass information seamlessly with minimal cost and minimal data loss between different components of a dimensional m...

We consider a strictly three-dimensional modeling technique as a basis for numerical simulations. Applications range from • a high-resolution indoor air flow modeling using the so-called thermal lattice Boltzmann method, • combined with a multizone network model for the building energy simulation, • to the scope of structural engineering, i.e. a three-dimensional high order solid finite element...

The geometrical approach to phase transitions is illustrated by simulating the hightemperature representation of the Ising model on a square lattice.

The d-dimensional unit cube [0, 1] is discretized to create a collection V of vertices used to define geometric graphs. Each subset of V is uniquely associated with a geometric graph. Defining a dynamic random walk on the subsets of V induces a walk on the collection of geometric graphs in the discretized cube. These walks naturally model addition-deletion networks and can be visualized as walk...

this paper presents a three-dimensional numerical investigation carried out in turbulent forced convection in a tube with helical ribs. enhancement of heat transfer using helically corrugated tubes has beenstudied experimentally by many researchers but there exist a few published numerical analyses results. the paper also introduces the results of heat transfer and friction factor data for inco...
