Authors: Hara Yusuke , Jahan Rumana A.
Published: March 2011

In this paper, we studied the effect of the temperature and the initial concentration of sodium bromate (NaBrO3) on the aggregation-disaggregation self-oscillation for a polymer chain. The polymer chain consisted of N-isopropylacrylamide (NIPAAm), Ru catalyst of the BZ reaction and Acrylamide-2-methylpropanesulfonic acid (AMPS) as a solubility control site. The concentration of sodium bromate and the temperature significantly affected the self-oscillating behavior and the period of the aggregation-disaggregation self-oscillation. Moreover, the amplitude of the aggregation-disaggregation self-oscillation of the AMPS-containing polymer solution decreased with time. The damping behavior is originating from the increase in the size of the polymer chain. In addition, this study clarified that the period of the self-oscillation of the AMPS-containing polymer solution in the strongly acidic condition was significantly shorter than that in the acid-free condition.

In this paper the authors have investigated the formability of AFS through experiments. the load versus punch stroke curve and deformation procedures of Aluminium foam sandwiche panels was investigated by performing V-bending experiments. A serious problem encountered in the V-bending was bending-induced large transverse shear deformation of the skin-core layer. It causes the delamination of the AFS. It was found from experimental observations that the large shear defomation progresses rapidly only at the final stage of V-bending. Consequently, the air-bending operation for Aluminium foam sandwiche panels is recommended for suppressing the shear deformation of skin-core layer to within an acceptable limit.

Authors: Li Jun Feng , Dai Wen Zhan , Wang Hui Jiao
Published: March 2011

Based on the characteristics of wavelet coefficients of images and fuzzy similarity measure, a novel image quality assessment is proposed in this paper. Firstly, the reference image and the distorted images are decomposed into several levels by means of wavelet transform respectively. The approximation and detail coefficients of the reference image (the distorted images) are as the reference sequences (the comparative sequences). Secondly, select the right membership function to map the referenced sequences and the comparative sequences to a membership value between 0 and 1 respectively. And calculate the fuzzy similarity measure values between the reference sequences and the comparative sequences respectively. Moreover, image quality assessment matrix of every distorted image can be constructed based on the fuzzy similarity measure values and image quality can be assessed. The algorithm makes full use of perfect integral comparison mechanism of fuzzy similarity measure and the well matching of discrete wavelet transform with multi-channel model of human visual system. Experimental results show that the proposed algorithm can not only evaluate the integral and detail quality of image fidelity accurately but also bears more consistency with the human visual system than the traditional method PSNR.

Authors: Li Hua Peng , Wang Dong , Xi Jian Hui , Li Yi Bo
Published: March 2011

Analysis and design cannot be solved until a proper model of hydraulic control system of earth pressure balance shield machine is built. There are two kinds of modeling methods in common use. (1) Dynamic mathematical modeling. Two models, transfer function and state space, are mainly included. For linear system, the two methods can be provided with a fairly complete theoretical framework. However, if the system is in the complicated working environment or it is non-linear, the modeling process needs a mass of mathematical verification. This has become a limitation for application of these methods; (2) Graphical Modeling. It is more direct for the complex hydraulic control system of earth pressure balance shield machine.

Authors: Yang Hai Qing , Kuang Bo Yan , Mouazen Abdul M.
Published: March 2011

Fast classification of soil with different texture is essential for site-specific application of different inputs into farmland. Total 178 soil samples with five textures were collected from Silsoe Farm, Cranfield University, England. Using a Vis/NIR spectrophotometer (LabSpec2500, ASD), spectra of soil samples were scanned for the study. Amongst various pre-processing methods, smoothing with moving average(MA), standard normal variation(SNV) and 1st derivatives were mainly investigated. PCA was applied to evaluate the discriminative capacity of the pre-processing methods on soil spectra. The score plot of PCs shows that 1st derivative with variable smoothing points can help classify soil samples much more effectively than others. With the increase of smoothing points, the cumulative variance of first few PCs in PCA tends to increase while the discriminative capability based on these PCs becomes worse. A trade-off between cumulative variance and discriminative capability should be concerned. In the study, an appropriate range of smoothing points in the 1st derivative is 7-21.

Published: March 2011

petroleum contamination is a very common environmental problem. Soil as the protective of groundwater, its remediation relates the security of groundwater, so we simulated the remediation of surface soil. From the experiment, we found that the natural attenuation of contaminated soil is a complicated process. The more processes contained, the easier petroleum attenuated. These processes can accelerate some of components reduce. Volatilization can only attenuate 24.85% petroleum, but if volatilization is coupled with biodegradation, that 89.99% petroleum can be attenuated. With the help of photodecomposition, 97.26% petroleum can be consumed. Volatilization action is a kind of physical attenuation mode, and it may not make some of components which are hard to volatilize into the air. Biodegradation action is a kind of biologic process which depend on the activity of bio-enzyme, and it need microbe compose a steady population. Photodecomposition is a kind of photochemical attenuation mode. If there are three or more attenuation processes exist, the powerful process will play a lead role, such as photodecomposition and biodegradation. From the result we can obtain that 59.83% contribution rate was caused by photodecomposition, and it can decay more petroleum than biodegradation and volatilization.

Authors: Tian Hua , He Jun Hui , Liu Lin Lin
Published: March 2011

Microporous manganese oxide in the form of laminar octahedral compounds (birnessite) has been synthesized facilely in a microemulsion system consisting of benzyl alcohol (BA), sodium dodecyl sulfate (SDS) and water. BA also served as a reducing reagent in the formation of manganese oxides. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Braunauer-Emmett-Teller (BET) measurements. The experimental results indicated that the reaction duration, temperature, and weight ratio of BA/SDS/H2O played key roles in determining the final morophologies of manganese oxide nanomaterials and also in their crystalline phase. Lower process temperature, shorter reaction time and lower BA ratio in the microemulsion were favorable for the formation of birnessite single phase. Mn3O4 nanocrystals appeared at a relatively higher temperature and more BA amount.

The question is that how to plan and lay out the m fitness clubs enables the shortest total distance C for all residents’ reach to their fitness club. In this paper, the Location Model in Operational Research is employed to make an analytical study on this issue to establish the location model and meanwhile gives mathematical solutions to the model in detail.

Authors: Wang Hong , Li Xian , Liu Shuang
Published: March 2011

Design and implement a car license plate identification system with the applications of Viola and Jones algorithm. This algorithm which is based on the AdaBoost method is trained and optimized for the best performance using large database of car license plate images. The final license plate identification system obtained a cascade of classifiers consisting of 8 stages with 1310 Haar-like features. Once the license plates have sufficient visibility and there are no other objects similar to the plate in images, this system operates perfectly and shows high correct identification rate with low false positive rate. And as integral image allows the Haar-like features to be calculated very fast, the system also finished the identification rapidly.

Nickel silicide/silicon/silica composite nanostructure, i.e., Ni31Si12/Si/SiO2, was synthesized successfully by a coevaporation method, using nickel formate and SiO powder as the source materials. The structure of product was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), transmission electron microscopy (TEM) and high resolution transmission electron microscope (HRTEM). The results indicated that the product had a rod morphology, which consisted of three parts with different morphologies and crystallographic structures. The top of the rod was a polycrystalline nickel silicide (Ni31Si12) nanoball with average diameter of 100 nm; the middle part was a single-crystal Si short rod with average diameter of 80 nm; the bottom part was an amorphous silicon oxide nanowire with average diameter of 60 nm. A possible growth mechanism of the composite nanorod was briefly discussed

Published: March 2011

Using FPGA for general-purpose computing has become an important research direction in high performance computing technology. However, it is not a lossless optimization method. Due to the impact of hardware reconfiguration overhead, data transmission cost, specific characteristics of programs, and other factors, the speedup of general-purpose computing on FPGA has visible difference. On the basis of in-depth analysis of FPGA architecture and development process, the main factors affecting FPGA implementation performance are pointed out, and a parallel cost model for FPGA based on static program analysis is proposed to provide judgment basis for using FPGA in general-purpose computing. The experiment results show that the algorithm estimates accurately FPGA execution performance.

Formal Reconfiguration of Enterprise Information System Flow Based on OKM and Binary Tree
Authors: Xue Chao Gai , Cao Hai Wang
Published: March 2011

This paper deals with a new approach to formal reconfiguration of enterprise information system (EIS) flow based on object-based knowledge meshes (OKM) and binary tree. Firstly, information system flow and its corresponding OKM form are discussed. Then the relations between knowledge points are defined, and the approach to structure expression of OKM is proposed, by which the EIS flows can be formally represented. And then, based on the formal representation, EIS flows can be reconfigured according to mapping rules between practical flow and structure expression of OKM. Finally, an order management flow in an EIS is taken as an example to show the feasibility and effectiveness of the approach.

Authors: Chee Ching Yern , Yaacob Iskandar Idris
Published: March 2011

Polyethylene (PE) film coated with polyurethane/nanosilica composite with varying composition were prepared and then exposed to ultraviolet radiation for accelerated weathering studies. The chemical and physical changes on nanocomposite coated PE film induced by UV exposure were studied by monitoring the changes in tensile strength, tensile modulus, elongation, carbonyl index, and visible light transmission. The effect of polyurethane/nanosilica composite coating on the durability and optical properties of polyethylene substrate was determined after 200 hrs and 500 hrs of ultraviolet exposure. There is no significant change was observed on visible light transmission for nanocomposite coated PE film after 500 hrs UV weathering. The mechanical properties of coated and uncoated PE were tremendously affected by UV exposure. PE coated with 4 µm of nanocomposite containing 6 wt% nanosilica showed less tensile properties deterioration compared to uncoated PE film after UV weathering. The surface protective coating of polyurethane/nanosilica composite with 6 wt% nanosilica content reduced the photodegradation rate of PE due to its excellent thermal stability compared to PE.

Published: March 2011

In this paper, highly-ordered TiO2 nanotube arrays (TNAs) were firstly fabricated by electrochemical anodization. Secondly, the as-prepared TNAs were used as precursors for hydrothermal treatment and large percentage of nanoparticles with special shape were achieved. Their photocatalytic activity was evaluated based upon the removal of methylene blue (MB) dye in the aqueous solution. In order to enhance the photocatalytic properties, we added a certain amount of AgNO3 solution (0.1M) in the hydrothermal treatment process and the experiment demonstrated that the addition of AgNO3 solution displayed an excellent improvement for the photocatalytic activity. Under sunlight irradiation, the methylene blue pollutant of 1×10−5M was almostly completely degraded by Ag -TiO2 nanoparticles within 300 min.
