Analyses and Modeling Impulse Noise Generated by Household Appliances

Investigation of the efficiency of various reactive mufflers by noise reduction and transmission loss analyses

Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reduction are investigated. In noise reduction analysis, the Navier-Stokes equations and k-ε model are us...

Restoration of Images Corrupted by Impulse Noise and Mixed Gaussian Impulse Noise Using Blind Inpainting

This article studies the problem of image restoration of observed images corrupted by impulse noise and mixed Gaussian impulse noise. Since the pixels damaged by impulse noise contain no information about the true image, how to find this set correctly is a very important problem. We propose two methods based on blind inpainting and `0 minimization that can simultaneously find the damaged pixels...

Household Appliances Control Device for the Elderly

An evaluation of musical earcons was carried out to see whether they are an effective and efficient method of delivering information about household appliances to elderly people. A test was carried out to explore the ability of the elderly subjects in remembering and learning the musical earcons. This test indicated a poor rate of recognition of the earcons. A second test that included the pres...

Removal of Impulse Noise by Selective Filtering

In this paper we present a novel structure for removal of impulse noise which is based on a combination of impulse detection and nonlinear ltering. The impulse detector is realized as a neural network which will be shown to possess a very simple structure. This means that, compared to traditional approaches, a signiicant gain in performance can be achieved with considerably smaller complexity. ...
