Geometric model, control & calibration of universal benchtop CT system
2007 Edition, Volume 4, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A universal benchtop CT system has recently been developed and installed at GE Global Research. The system consists of a source, detector and phantom table that are mounted on a set of high accuracy motion stages. These stages permit positioning and...

Fuzzy Geometric Modeling
2009 Edition, August 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Fuzzy geometric modeling provides a useful tool to introduce uncertainty into mathematical spline model. In this paper a new concept of a geometric modeling is presented, based on the theory of fuzzy numbers. By the notion of fuzzy number we...

Geometric Modeling Technology
1981 Edition, January 1, 1981 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The geometric model is an essential element of the design description. It is an abstract representation of the form and size of the object that serves as a medium of communication. The geometric model must hold sufficient information to answer...

Geometric model of muscle contraction
2003 Edition, Volume 2, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We use a function transformation that leaves volume unchanged as the basis for geometric model of muscle contraction. The model is built after making an experiment on a frog leg muscle under single electrical stimulus.

Geometric model of silicon nanotubes
2010 Edition, February 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we extend both the rolled-up and the polyhedral models for single-walled silicon nanotubes with equal bond lengths to models having distinct bond lengths. The silicon nanotubes considered here are assumed to be formed by sp3 hybridization with different bond lengths so...

Interval methods in geometric modeling
2000 Edition, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper is about using interval computations in location, simplification, and root-finding for multivariate implicit functions that are used as shape primitives in a set-theoretic (that is, a CSG) geometric modeller. Three problems are discussed, and solutions to them presented:...

Geometrical Model of Communication
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

There are different classes of communication channels with variable parameters. Nowadays the following models of such communication channels are known: 1. With casually changing signal phase. 2. With smooth (general) fading. 3. With multiplicative noise error. 4. With selective...

3D Geometric Model Region Partition Method
2008 Edition, June 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Focusing on detail preserving in triangle mesh model simplification, a novel 3D geometric model region partition method based on self-organizing feature map is proposed. Firstly, computing the character vector of each vertex of 3D geometric model....

Estimating bandwidth coverage using geometric models
2016 Edition, June 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Geometric models are a proven aid for calculating the CapEx needed for a network deployment and used widely by telecommunication network operators for their access networks. However, for the economic viability an accurate estimation of the delivered bandwidth is important as...

Euler Formulas and Geometric Modeling
1985 Edition, Volume 5, August 1, 1985 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This Physial Approach to the Euler Formula Demonstrates how Different version Can be in this article we demonstrates how different versions can be Obtained And how They Can Be Used in Boundary Geometric Modeling
