The advantage and necessity of this frame is that it has no vanishing curvature, which solves a serious problem working on usual Bishop frame since zero curvature prevents to define normal and
binormal vectors.
We can choose this local coordinate system to be the Serret-Frenet frame consisting of the tangent vector [??](t), the
binormal vector [??](t), and the normal vector [??](t) vectors at any point on the curve given by
where d[V.sup.2.sub.n-2] and [[epsilon].sub.[xi][eta]] represent the volume element on (n - 2)-dimensional space-like bifurcation surface ([SIGMA]) and
binormal vector to [SIGMA] satisfying the relation [[epsilon].sub.[xi][eta]][[epsilon].sup.[xi][eta]] = -2.
The four unit vector functions are called the tangent, normal, first
binormal, and second
binormal.
Negative response latency was observed when the size was larger than 3.2 x 3.2mm (p < .05,
Binormal test).
The Maximum likelihood estimation of a
binormal Receiver-operating characteristic (ROC) curve from categorical rating data at 95% confidence interval was calculated (JROCFIT Version 1.0.2).
Approximated ROC curves were calculated on the basis of a
binormal model to compare the area under the curve (AUC) (16).
Under mild conditions we will see that a curve motion following (2) describes a curve [gamma] evolving under the
binormal flow, with velocity depending on curvature and torsion (19), and determines an immersed surface, [S.sub.[gamma]], in [M.sup.3.sub.r] ([rho]).
The
binormal selection curve is the addition of two normal curves with a weighting factor (w) (Santos et al., 2003; Madsen, 2007) and the relative retention in this case is given by:
They can also import 3D scenes and contents from an existing 3D PDF as well as convert all polygons to triangles of a 3D model, and may also generate tangent and
binormal data for all meshes in 3D models.
