Effects of Facial Transformations on Accuracy of Recognition
The Journal of Social Psychology, 1994Alterations of facial features between the initial phase of a memory task and a later recognition test lower identification accuracy. The effects of leaving on, leaving off, adding, or removing targets' eyeglasses or beards on identification accuracy were examined in two experiments with American undergraduates.

The transformer accuracy on-line evaluation system
2011 International Conference on Electrical and Control Engineering, 2011The accuracy of current transformer (CT) and voltage transformer (VT) is important guarantee of power system protection, monitoring and measurement. A new method based on live working technique for transformer accuracy evaluation is proposed in this paper.

Improving classification accuracy using evolutionary fuzzy transformation
Proceedings of the 11th Annual Conference Companion on Genetic and Evolutionary Computation Conference: Late Breaking Papers, 2009Selection of a classifier is only one aspect of the problem of data classification. Equally important (if not, more so) is the pre-processing strategy to be employed. In this paper, a pre-processing step is proposed in order to increase accuracy of classification.

A New High Accuracy Current Transformer
Transactions of the American Institute of Electrical Engineers, 1929This paper is presented for the purpose of describing a new method of compensation, by the use of which the ratio and phase-angle errors of current transformers are materially reduced. There are several methods by which the ratio and phase-angle errors of current transformers may be reduced. The following are those which are most commonly used: 1.

Inductive current transformer accuracy of transformation for the PQ measurements
Electric Power Systems Research, 2017Abstract Inductive current transformer made of magnetic cores with high permeability are used for accurate wideband transformation of distorted current required by the power quality (PQ) measurements. However, such solutions are often characterized by not acceptable additional secondary current distortion in condition of variation of primary current ...

Transforming the empirical likelihood towards better accuracy
Canadian Journal of Statistics, 2017AbstractUnder‐coverage has been a long‐standing issue with the empirical likelihood confidence region. Several methods can be used to address this issue, but they all add complexity to the empirical likelihood inference requiring extra computation and/or extra theoretical investigation.

Accuracy of Multivariable Refinable Functions and Two-Scale Similarity Transform
Acta Mathematica Sinica, 2000The paper considers refinable function vectors \(\Phi\) with dilation matrix \(M=\text{diag}(2,2,\dots, 2)\). Let \(m(\xi)\) be a refinement symbol of the refinable vector \(\pmb\Phi\) and let \(\Phi\) provide accuracy \(p\). Then, under some additional conditions, the vector \(\pmb\Psi\) with refinement symbol \[ \tilde m(\xi)=T( 2\xi)^{-1}m(\xi)T(\xi)

The effect of instrument transformer accuracy class on the WLS state estimator accuracy
2013 IEEE Power & Energy Society General Meeting, 2013The measurement chain of the power system consists of various components introducing their associated uncertainty to the measured quantity. Although, it is important to identify and quantify the individual uncertainties of the measurement chain components and consequently the combined measurement chain uncertainty, it is nearly impossible to do this ...
