Triangle

In technical analysis, a series of high and low prices for a security that, when plotted on a chart, looks vaguely like a triangle. A triangle indicates that investors do not know whether a bull market or a bear market will prevail. If the triangle breaks upward, it is a bullish sign, but if it breaks downward, it is a bearish sign. A triangle is also called a wedge. See also: Ascending sign, Descending sign.

triangle
In technical analysis, a chart pattern indicating the convergence in the movement of successive high and low prices and characterized by a formation that resembles a triangle turned on its side. A triangle indicates a period of combat between bulls and bears with the technical analyst having to determine the winner. If prices break out of the triangle on the upside, it is a bullish sign. A breakout on the downside indicates the bears are winners. The closer the breakout occurs to the point of the triangle, the less conclusive the signal to buy or sell. Also called coil, flag, pennant, wedge. See also ascending triangle, descending triangle.

The case of [M.sub.12] is similar: it has the same 1-simplices as [M.sub.1], and once we impose commutativity of (3.5) on the 3-simplices, any 2-simplex ([phi]|[psi]) must obey (3.4) in order to have a 3-simplex with the boundary of [s.aub.1] ([phi]|[psi]).
Again, a simplicial map C [right arrow] [M.sub.12] is given by the images (A,m) of the non-degenerate 1-simplex [alpha], ([t.sub.1] [t.sub.2]) of the non-degenerate 2-simplex [tau] and ([e.sub.1]|[e.sub.2]) of the non-degenerate 2-simplex [epsilon].
Assuming unit area for the 2-simplex [[u.sub.1], [u.sub.2], [u.sub.3]], it is again easy to show that the infinitesimal area of such triangle is
Since (25) is valid for any C, it immediately follows that, within the 2-simplex [[u.sub.1], [u.sub.2], [u.sub.3]], we have
2(a), we can find that there are many pixels appear in the center area of the 2-simplex, whose dominant scattering mechanism cannot be clearly defined.
In fact, the four mixed categories can be easily determined in the standard 2-simplex. For example, the fourth category "Odd + Vol" means that the two scattering mechanisms: surface and volume are dominant, moreover [P.sub.s] and [P.sub.v] are very close.
The map [Mu] thus satisfies the preconditions of Sperner's Lemma, and therefore it carries some 2-simplex in the subdivision [Sigma](T) to an output simplex labeled with all three values.
For example, the one-round three-process protocol complex of Figure 25 is a not subdivided 2-simplex, although it does contain the subdivided 2-simplex shown on the right-hand side of Figure 26.
