rather than to use ordinary normal surface theory on a general triangulation obtained by decomposing the truncated tetrahedra
To be practical, the space is discretized into tetrahedra
constructed by the Delaunay tetrahedralization  and the free-space support is evaluated for the tetrahedra
2-]) in lithium tetraborate tetrahedra

i], we denote the collection of all triangular faces f of tetrahedra
[tau] [member of] [[XI].
j] needed for the MRA, we use a sequence of tetrahedra
, beginning with a basic net [T.
A triangular grid, quadrilateral grid, tetrahedral grid, and hexahedral grid is a grid consisting entirely of triangles, quadrilaterals, tetrahedra
and hexahedra, respectively.
The generation of meshes of well-shaped tetrahedra
This example shows the time required for a finite element solver for problems with different numbers of tetrahedra
I] corresponds to a vector of the contrast values located at the tetrahedra
centroids in the domain D, and [[[?
If, for instance, you wanted to make a very dense, rigid, hard ceramic, you would probably be better off making the powder from tetrahedra
," New Scientist quoted Jaoshvili's adviser, Paul Chaikin, as saying.
The Princeton researchers placed pairs of tetrahedra
face-to-face, forming a kissing pattern that, viewed from the outside of the container, looks strangely jumbled and irregular, Torquato said.
People generally decompose each cube into a set of tetrahedra
where a function is defined by linear interpolation, to apply such techniques to rectilinear volumetric data.
