Authors: Lin Jeng Jong
Published: July 2013

An intelligent prediction system theory-based on geometric modeling is developed in the study. The damage behaviors of woven fabric can be predicted by using the developed prediction system, which is theory-based on finite element analyses (FEAs) approach. A unit cell model based on slice array model (SAM) for plain weave fabric is employed to predict the elastic properties. An unit cell is divided into slices either along or across the loading direction in the SAM to predict the mechanical properties of the fabric. The results show the geometric modeling approach based on SAM is pretty promising in predicting the mechanic properties (e.g., initial Young's modulus, surface shear modulus and Poisson's ratio) of the woven fabric. In the experimental approach, the damage behaviors of plain weave woven fabric are tested under quasi-static conditions and the tensile load-displacement curves of the fabric are obtained and the damage morphologies are also observed. The design of composite can become easier and more efficient by using geometric modeling approach to predict the probable damage due to tensile given to the woven fabric as such an enhancement material.

Based on multistage theory and NSCT, a new feature-based image watermarking scheme is proposed in this paper. Firstly, the multistage Harris detector is utilized to extract steady feature points from the host image; then, the local feature regions (LFR) are ascertained adaptively according to the feature scale theory, and they are scaled to a standard size; finally, the digital watermark are embedded into no subsample contour let low frequency area, in the low frequency regions made pseudo-Zernike moment calculation. Experimental results show that the proposed scheme is not only invisible and robust against common signals processing such as median filtering, sharpening, noise adding and JPEG compression et al, but also robust against the unclassified geometric attacks such as rotation, translation, scaling, row or column removal, shearing, local geometric distortion and combination attacks et al.

High level of humus existing in oil-spilled marsh soil could co-extract with DNA to inhibit PCR amplification. We established a stable DNA extracting protocol by modifying direct lysis and activated sludge DNA extracting procedures: with 0.1g/ml PVPP in extracting buffers to pretreat soils and three cycles of freeze-thawing treatment added, by employing lysozyme and 15% SDS, through reducing duration of water bath and digesting RNA with Rnase A before phenol/chloroform extraction. With high concentration of DNA, this protocol provided lower OD230/OD260 value and appropriate OD260/OD280 ratio, which both were significantly different from 0.1g/ml PVPP & 1% CTAB method, indicating pure DNA solutions. Additionally, DNA purity was further checked by amplifying V3-V5 regions of 16S rRNA on bacterial DNA with primer pair 341F/929R.PCR products confirmed that crude oil-spilled marsh soil pretreated by PVPP protocol and extracted by modified extracting procedure could clear humus better and obtain good quality of DNA.
