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.

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.

That study indicated that surface normal angle error well identified socket regions deemed by clinical examination (static fitting) to be improperly shaped.
The combination of radial difference images and surface normal angle difference images (Figure 4) provided insight relevant to interpretation, similarly to a previous investigation [8].
Computationally, it was the mean inverse hyperbolic arctangent of the dot product of the surface normals (Equation (2)):
This happened because surface normal angle was a more sensitive measure to slight mismatches in shape than were MRE and IQR.
A closed contour of high surface normal error is a regional distortion, i.
epsilon] = the angle between azimuth angle [phi] and the projection of the surface normal onto the horizontal plane; and
s = + 1 if the projection of the surface normal onto the horizontal plane is in the same direction as [phi], and equal to -1 otherwise.
The angle between the surface normal vector and the illumination vectors is [Theta].
90 [degrees] / 5 [degrees]) potential classes exist, data fell into 12 classes centered around an angle of 45 [degrees]; there were no grid cells with surface normal vectors at an angle greater than 75 [degrees] or less than 15 [degrees] to the illumination vector in the study area.
