Fig. 10.01. Utility power transformers are typically grounded to earth ground near the transformer, and again at the input to the electrical junction box or first switching panel. The switching panel, in turn, may be connected to a rod driven into the earth to ensure that it too is at true ground potential. Control Panel Grounding CONTROLLING NOISE Controlling noise in measurement systems is vi...

introduction one of the most important pre-processing steps in optical coherence tomography (oct) is reducing speckle noise, resulting from multiple scattering of tissues, which degrades the quality of oct images. materials and methods the present study focused on speckle noise reduction and edge detection techniques. statistical filters with different masks and noise variances were applied on ...

In this paper we present a new perspective on noise reduction for nearest-neighbour classifiers. Classic noise reduction algorithms such as Repeated Edited Nearest Neighbour remove cases from the training set if they are misclassified by their nearest neighbours in a leave-one-out cross validation. In the approach presented here, cases are identified for deletion based on their propensity to ca...

background: formaldehyde (h2c = o), is a member of aldehyde family with a simplest organic molecule, used in various industries. the aim of this experimental study was to investigate the effects of simultaneous formaldehyde and noise exposure on hormonal pituitary-gonadal axis in adult male mice. methods: 46 adult male mice were randomly assigned to one control group and three experimental grou...

Motion Compensated Noise Reduction

This article presents a new subspace-based technique for reducing the noise of signals in time-series. In the proposed approach, the signal is initially represented as a data matrix. Then using Singular Value Decomposition (SVD), noisy data matrix is divided into signal subspace and noise subspace. In this subspace division, each derivative of the singular values with respect to rank order is u...
