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...

This paper deals with the problem of identifying the nature of noise in order to apply the most appropriate algorithm for de-noising. The key idea involves isolation of some representative noise samples and extraction of their features for noise identification. The isolation of the noise samples is achieved through application of filters. Statistical features are extracted and the minimum dista...

The relation between performance and stress is described by the Yerkes-Dodson Law but varies significantly between individuals. This paper describes a method for determining the individual optimal performance as a function of physiological signals. The method is based on attention and reasoning tests of increasing complexity under monitoring of three physiological signals: Galvanic Skin Respons...

Background: With industrial development, many production processes emit high levels of noise, presenting problems for society. This emission causes an environmental impact on employees and also on the surrounding environment. Materials and Methods: The present study was performed with the objective of analyzing the noise emission in a plastic recycling plant in the municipality of Caçador, San...

Vibration isolation and noise control technologies are used in submarines on multiple systems and there are various reasons for employing these technologies. One of the principal reasons is to minimise the acoustic signature of the submarine so that it is difficult to detect. This paper contains descriptions of conventional and emerging noise and vibration isolation technologies that have and c...

Images are often corrupted by impulse noise in the procedures of image acquisition and transmission. Impulse noise is a category of acoustic noise which includes unwanted sharp sounds like click and pops. To avoid the damage on noise liberated pixels, the switching medium filters are used which consists of impulse detection and noise filtering. In our project, we propose an efficient denoising ...
