In the application of the Almost Band Algorithm to problems involving sharp separations, it was required that all of the corrected flow rates be positive and that the temperatures lie within the range of the curve fits. In this procedure, the vector correction Ax was reduced by an appropriate scalar a until all of the corrected flow rates were positive and the corrected temperatures were within the range of the curve fits, that is,... [Pg.189]

Extensive studies by Jurs et. al. C1313 with mass spectra showed that a reflexion of the decision plane yields the highest convergence rate. Other methods of weight vector correction and a method with a small positive feedback upon correct classification were investigated by the same authors but did not give better results-... [Pg.35]

Normalization of the weight vector can be accomplished after each weight vector correction as proposed by Jurs et. al. C123, 167, 168, 2333. Another method was proposed by Wangen, Frew, and Isenhour C3203 who included the normalization into the weight vector correction procedure. [Pg.40]

The summation is taken over all patterns or only over those which were used for weight vector corrections during the training. Features with smallest values for g are eliminated because they have the smallest average contribution to the classification (or to the calculation of the scalar product) 11131/ 1603. [Pg.112]

This situation may be met when aiming to describe dynamic electron correlation starting from a single, multi-determinantal reference vector. Correction schemes based on perturbation theory (PT) have been applying successive Gram-Schmidt orthogonahzation in such circumstances [5-7], occasionally combined with Lowdin s symmetrical [8] or... [Pg.222]

The approximation V = P is inadequate for determining the vector corrections to the scalar propagation constant on the elliptical fiber. In Section 34-8 we use Green s functions to show that correct to second order in eccentricity is given by... [Pg.384]

Such step-limiting is often helpful because the direction of correction provided by the Newton-Raphson procedure, that is, the relative magnitudes of the elements of the vector J G, is very frequently more reliable than the magnitude of the correction (Naphtali, 1964). In application, t is initially set to 1, and remains at this value as long as the Newton-Raphson correotions serve to decrease the norm (magnitude) of G, that is, for... [Pg.116]

The LIN method ( Langevin/Implicit/Normal-Modes ) combines frequent solutions of the linearized equations of motions with anharmonic corrections implemented by implicit integration at a large timestep. Namely, we express the collective position vector of the system as X t) = Xh t) + Z t). (In LN, Z t) is zero). The first part of LIN solves the linearized Langevin equation for the harmonic reference component of the motion, Xh t)- The second part computes the residual component, Z(t), with a large timestep. [Pg.246]

A somewhat similar problem arises in describing the viscosity of a suspension of spherical particles. This problem was analyzed by Einstein in 1906, with some corrections appearing in 1911. As we did with Stokes law, we shall only present qualitative arguments which give plausibility to the final form. The fact that it took Einstein 5 years to work out the bugs in this theory is an indication of the complexity of the formal analysis. Derivations of both the Stokes and Einstein equations which do not require vector calculus have been presented by Lauffer [Ref. 3]. The latter derivations are at about the same level of difficulty as most of the mathematics in this book. We shall only hint at the direction of Lauffer s derivation, however, since our interest in rigid spheres is marginal, at best. [Pg.587]

Here and below, T , 1, , and e, i, j = 1,. . . , 5, denote atomic position vectors, atom-atom distances, and the corresponding unit vectors, respectively. In order to construct a correctly closed conformation, variables qi,. . . , q4 are considered independent, and the last valence angle q is computed from Eq. (7) as follows. Variables qi,.. ., q4 determine the orientation of the plane of q specified by vector 634 and an in-plane unit vector 6345 orthogonal to it. In the basis of these two vectors, condition (7) results in... [Pg.126]

Another principal difficulty is that the precise effect of local dynamics on the NOE intensity cannot be determined from the data. The dynamic correction factor [85] describes the ratio of the effects of distance and angular fluctuations. Theoretical studies based on NOE intensities extracted from molecular dynamics trajectories [86,87] are helpful to understand the detailed relationship between NMR parameters and local dynamics and may lead to structure-dependent corrections. In an implicit way, an estimate of the dynamic correction factor has been used in an ensemble relaxation matrix refinement by including order parameters for proton-proton vectors derived from molecular dynamics calculations [72]. One remaining challenge is to incorporate data describing the local dynamics of the molecule directly into the refinement, in such a way that an order parameter calculated from the calculated ensemble is similar to the measured order parameter. [Pg.270]
