Heuristically, it makes an orthogonal transformation of the axes to an orientation that matches the shape of a p-dimensional plot of the data. This enables principal components analysis to do the following: 1. Find linear combinations of the vector components that have maximum variance, subject ...
Learn how to do vector addition and scalar multiplication in component form, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.
Properties of linear and quadratic invariants of correlation tensor-function of vectorial periodically non-stationary random processes are considered. We analyze the properties of their estimations, given in the form of trigonometric polynomials, whose Fourier coefficients can be obtained using averaging on...
In the q+ = 0 frame, we define the form factors extracted from the vari- ous combinations of vector and tensor currents. In Section 3, we set up the current matrix elements for the form factors in an exactly solvable model based on the covariant BS model of (3 + 1) dimensional ...
1.A universal formula of MINQUE of variance components;方差分量的MINQUE通用公式 2.It is concluded that the phasor can be represented by the form of a-jb,and thus the impedance and negative sequence component can be calculated correctly.通过分析近年发表的相关傅氏算法的文献,提出对几个问题的质疑...
When designing the impeller, the flow vector is assumed to be parallel to the axis of rotation of the impeller at the pump inlet; thus, it becomes more convenient to use Eq. (10.12) for head estimation: (10.12)gH=Vx2cotβ1cotβ1-cotβ2 where Vx is the axial component of the fluid ...
An optimal componentwise Krawczyk-Moore type iteration method is constructed by use of the new centered form of Baumann. Ein optimales komponentenweises Iterationsverfahren vom Krawczyk-Moore-Typ wird eingeführt. springer Continuity and differentiability of vector fields are defined componentwise. ...

The diagnostic features can be built on the basis of these characteristics or can be formed using the probabilistic characteristics of stationary components ξk(t) that form PCRP. The mean function of process (3) is determined by formula (4)m(t)=∑k∈Zmkeikω0t, where Fourier coefficients...
