Traditional methods for resistivity measurements of concrete have to use two plate electrodes at opposite sides of a prism specimen. The major drawback of such a method is that the electrodes can be easily detached from the specimen due to shrinkage of concrete. Thus the measurement of resistivity.....

Halftoning is a method to represent multi-tone images using only two-tone colors. Such methods are used widely in computer printers, newspaper/magazine/book publishing, fax machines, etc. From a distance, halftoned images resemble images with multi-tones.This new invention uses Data Hiding Error Dif.....

Volatile organic compounds (VOCs) and carbon monoxide (CO) in the air are contaminants and are harmful to human health. Methods have been developed to eliminate the contaminants. Supported metal catalysts are found to be effective in low-temperature oxidation of CO and hydrocarbons and selective ox.....

Thin-film transistors (TFTs) are typically formed in a semiconducting layer placed on an insulating layer. TFT structure with source and drain resistance is impossible to be lower than that offered by metallic source and drain by conventional method of silicidation or thickening of the source and dr.....

Traditionally, glass colored with metal ions have been used to manipulate light transmission, but this method suffers the disadvantages of consuming tremendous energy to melt metal oxides and of the complications associated with the high-temperature processing. Polymers are replacing glasses in many.....
