Effect of temperature on burst phenomena in aged mineral oil under non-uniform fields

Canadian Electrical Engineering Journal, 1986
Presents the experimental results of high field conduction current burst phenomena in aged transformer oil using point-plane configuration. The effect of temperature and field strength variations on burst parameters are emphasized. It was found that bursts can be classified according to their direction. Generally, the amplitude of bursts increases with

Study of DC conduction in aged transformer oil under non-uniform high fields

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1983, 1983
This paper emphasises experimental results of DC conduction current in aged transformer oil using point-plane configuration. The effects of oil dehydration and filtration, anode material and field strength are investigated and discussed. It is found that i-t and i-E characteristics display exponential “behaviour and tunneling phenomenon, respectively ...

Effect of Age on Strength of Unfired Soil Lime Bricks Containing Non Uniform Coconut Fibers

Applied Mechanics and Materials, 2013
In some provinces in Indonesia, like West Java, fired clay and unfired soil lime bricks co-exist as non standard bricks. Low rise buildings and rural houses in Indonesia are often constructed with non-standard bricks. The paper discusses strength-time relation of unfired bricks reinforced with and without natural fibers.

Enhanced age estimation by considering the areas of non-skin and the non-uniform illumination of visible light camera sensor

Expert Systems with Applications, 2016
We propose an age estimation method using a weighted MLBP based on fuzzy system.With two inputs, optimal weights are obtained by fuzzy system without training.Optimal weight is assigned to histogram features by MLBP method in each sub-block.Age is estimated by SVR based on the fusion of weighted MLBP and Gabor features.

Influence of Non-Uniform Current Distribution on AC Transport Current Loss in Bi-2223/Ag Tapes

IEEE Transactions on Applied Superconductivity, 2006
This paper presents the influence of current distribution on AC transport current loss in multi-strand high-temperature superconductor (HTS) tapes. The current-distribution-dependent-AC loss is analyzed by introducing a current distribution parameter. We calculated AC loss of multi-strand HTS tapes numerically and performed AC loss measurements as well.

P‐48: Pixel‐Based Optical Feedback to Correct Ageing and Non‐uniformities in Large‐Area Displays

SID Symposium Digest of Technical Papers, 2006
Abstract Current AM addressing with peripheral drivers is not suited to tackle the problem of individual pixel deterioration for example due to aging or non‐uniformity of different pixels in the display (a problem proportional to the size of the display). Therefore we pro‐pose to integrate the driver electronics underneath each pixel,
