    Abstract: The ability of a textile fabric to support load at an angle to the two principal directions is important in structures used in load bearing technical applications. Using a simple approach, the angular rupture properties of a plain woven fabric were modeled. The primary restriction imposed was that the fabric width was restrained so that lateral contraction could not occur. This eliminated the possibility of the cut ends of the yarns playing a role and complicating the theoretical treatment. The input parameters were the yarn tensile properties, the fabric warp and weft counts, and the angle to the principal axis at which the properties were determined. A novel test method was developed that conformed to the restriction imposed in the theory and allowed the computed and the measured properties to be compared. Good agreement obtained validates the model and illustrates a new approach to investigating fabric mechanical properties.

    Automatic Recognition of Fabric Nature by Using the Approach of Texture Analysis

    Abstract: This paper proposes an approach to texture analysis that could be used to recognize the fabric nature and type of the main weaving texture. First, the color scanner captures the fabric image and saves it as a digital image and then the wavelet transformation is used to display the image texture. The co-occurrence matrix is then be applied to calculate the texture characteristics, such as angular second moment, entropy, homogeneity, and contrast, and finally, the learning vector quantization networks (LVQN) are adopted as a classifier to categorize the fabric nature and the type of weaving texture. The experimental result showed that this approach could automatically and accurately classify the fabric nature, including woven fabric, knitted fabric and non-woven fabric, and the type of its main weaving texture, such as plain, twill or satin weave, single or double knitted and non-woven fabric.

    Abstract: This paper studies the combustion characteristics and performances of a LPG/diesel blend-fuel engine; the influences of mixing ratio of LPG in diesel on the ignition timing, in-cylinder pressure, heat-release rate, specific fuel consumption, power output, and exhaust emissions have been identified. The results indicate that the ignition delay of blend fuel was obviously longer than that of diesel and the higher the mixing ratio of LPG in diesel, the longer the ignition delay. When the mixing ratio of LPG in diesel was 10 per cent, the peak in-cylinder gas pressure and the peak rate of pressure rise were slightly higher than those of diesel, and the corresponding crank angles at which the peak values occurred were almost the same as those of diesel. When the mixing ratio was 30 per cent, the peak in-cylinder pressure and the peak rate of pressure rise were lower than those of diesel, and the corresponding crank angles were retarded. With the increasing of mixing ratio of LPG in diesel, the peak rate of heat release increased and the corresponding crank angles were retarded. The equivalent specific fuel consumption of L10 was the same as that of diesel, but that of L30 was slight higher. The power output of the diesel engine was higher than those of L10 and L30 at speed characteristic of full load, especially at high engine speed. With the increasing of mixing ratio, the smoke emissions and NO x emissions were greatly reduced, and CO emissions decreased too, but HC emissions slightly increased.

    Abstract: In June 2008, the AWWA Board of Directors approved a new policy statement on research. This policy emphasizes that research is an important function for every utility and that research activities should be a legitimate cost of service to be included in a utility—s water rate structure. At the 2008 Annual Conference, JOURNAL AWWA conducted a roundtable discussion about research and related issues such as the nature of research, why it is important, how it can be benchmarked, customers— views on research, and its perceived value. The participants were Mark LeChevallier, director innovation and environmental stewardship, American Water (moderator), Voorhees, N.J.; Mike Grimm, associate, The Cadmus Group Inc., Watertown, Mass.; Mark Knudson, chief engineer, Tualatin Valley Water District, Beaverton, Ore.; David Rager, director, Greater Cincinnati Water Works, Cincinnati, Ohio; Brian Ramaley, director, Newport News Waterworks, Newport News, Va.; David Rexing, manager, water quality research and development, Southern Nevada Water Authority, Henderson, Nev.; Robert Renner, executive director, Water Research Foundation, Denver, Colo.; Terry Rolan, McKim Creed Engineers, Maxton, N.C.; John Scheltens, consultant, Hot Springs, S.D.
