Principal axes of a quadric (Geom.), three lines in which the principal planes of the solid intersect two and two, as in an ellipsoid. Principal challenge. (Law) See under Challenge. Principal plane. See Plane of projection (a), under Plane. Principal of a quadric (Geom.), three ...
Principal of a quadric (Geom.), three planes each of which is at right angles to the other two, and bisects all chords of the quadric perpendicular to the plane, as in an ellipsoid. – Principal point (Persp.), the projection of the point of sight upon the plane of projection....
For a conic, a straight line that passes through the midpoints of all the chords perpendicular to it. For a quadric surface, the intersection of two principal planes. (mechanics) One of three perpendicular axes in a rigid body such that the products of inertia about any two of them vanish...
Principal Component Analysis (PCA) is a multivariate analysis that reduces the complexity of datasets while preserving data covariance. The outcome can be visualized on colorful scatterplots, ideally with only a minimal loss of information. PCA applicati

Our algorithm ensuresvector-quantization accuracy similar to thatof computationally-expensive PCA trees withsimilar time-complexity to that of lower-accuracy RP trees.APD trees use a small number of power-method iterations to find splitting planes forrecursively partitioning the data. As suchthey ...
The middle surface of a shell of revolution is formed by rotating a plane curve (generator) with respect to an axis in the plane of the curve as shown in Fig. 10-5. The lines of principal curvature are called the meridians (surface curves intersected by planes containing the axis of ...
When the doors are in open position, they lie substantially in the planes of the bottom walls 49 of the chambers and their outer edges are closely adjacent the ends of the conveyors as most clearly shown in Figures 4 and 5. Similarly, crank arm 81 carries a roller 90 which is en- 4 ...
Flat 2D baseplanes result from an echo sequence which delays acquisition until after probe ring down and receiver recovery. The technique used for synchronizing the pulses to 1/3 the rotor period without relying on absolute rotor-frequency stability is described. The PHORMAT spectrum of methyl-伪...
