Authors: Huang Chung Ho , Ho Chih Hsuan
Published: July 2013

This paper aims to investigate on producing lightweight aggregates made from the waste stone sludge. It was utilizing the mechanism of high temperature solid solution method as well as in coordination with the production method of reservoir sediments lightweight aggregates to conduct an investigation on the development of lightweight aggregate using stone sludge. The investigation shows that the analysis results for the stone sludge are not in the limits of the expandable region of the ternary diagram due to the high content of FeOx. That caused the expandable temperature range was narrow, the expandability of aggregate was poor and the aggregate particle density was relatively high. But, it still could be producing lightweight aggregates made from the waste stone sludge in this paper. The better solution may be to add the high-content organic materials to adjust chemical composition, such as water purification sludge, sewer sludge, reservoir sludge etc.

Authors: He Li Juan , Zhou Yu Cun
Published: July 2013

It proves that steering wheel shimmy is a vibration of stable limit cycle occurring after Hopf bifurcation, which is elaborated by nonlinear dynamics theory, and the control objectives of shimmy are proposed according to its bifurcation properties. Numerical analysis of bifurcation characteristics has been conducted with a nonlinear shimmy model whose parameters come from a domestic automobile with independent suspension. The results indicate that when the speed reaches 49.98Km/h, supercritical Hopf bifurcation occurs to the system and stable limit cycle appears, i.e. wheels oscillate around the kingpin at the same amplitude; when the speed comes to 76.30 Km/h, Hopf bifurcation occurs again and limit cycle disappears. The bifurcation speed and amplitude of limit cycle match the shimmy speed and amplitude measured from road experiments very well, which confirms the conclusions that shimmy is a vibration of stable limit cycle occurring after Hopf bifurcation at critical speed.

Authors: Yong Cheng
Published: July 2013

The analysis method that the microwave digestion - graphite furnace atomic absorption spectrometry (GF-AAS) determination of trace impurity element arsenic in the nanotitanium dioxide has been built. It uses a mixture digestion reagent which is composed of a certain concentration and the proportion of hydrofluoric acid and nitric acid in the experiments, and then combined with high pressure microwave heating technology so as to quickly and completely digest the nanotitanium dioxide sample into solution. The composition and ratio and amount of the mixed digestion reagent, and the best microwave heating control program are all optimized in this paper, which not only solved the problem of the digestion of titanium dioxide and the loss of the analyte arsenic that is likely to be volatile in the high temperature digestion process, but also ensure that high content of titanium matrix in the low acidity solution is still existing in a stable complex ion form to avoid hydrolysis by complexation of the fluoride ion. Therefore, it can greatly reduce the detection affection of acidity and avoid the erosion of GF-AAS graphite tube. In order to eliminate the influence of the thermal stable titanium dioxide matrix on the determination of volatile trace element arsenic, the type of graphite tube, graphite furnace atomization procedures and atomic absorption spectrometer detection parameters all have been optimized through the matrix effect testing. The detection limit is 0.000 001% and the recovery rate is in the range of 93.0% to 106.0%. Otherwise, RSD is less than 9.36%, which is consistent with ICP-MS detection method.

Published: July 2013

Aimed at decreasing the tension variation during transforming process of 1+4 aluminum hot rolling mills unit in one factory of Henan, we analyzed the factors affecting tension variation and improved the tension formula of hot rolling mills process considering the influence of tension on forward slip value. The tension forming process of hot rolling mills from stand 1 to stand 4 is simulated, and the tension structure diagrams of the four-stands are constructed. Due to non-linear characteristics of the aluminum hot rolling mills tension system, conventional PID controller could not meet the requirement of the system. So we proposed the mixed control of Cerebellar Model Articulation Controller (CMAC) coupled with PID to solve the problem of online parameters control and we used Particle Swarm Optimization (PSO) algorithm to optimize PID controller parameters. By simulation, it could be found that the using of PSO+CMAC significantly reduced surplus adjustment and transition time, and strip tension coupling degree among stands was also reduced.

Published: July 2013

This research carried out field tests on nine vertical anchors to investigate their behavior in gravel of Taichung Basin. An anchor can be categorized as a deep anchor when the free length Z exceeds 8D (D is the diameter of the anchor). The shape of the heave on the ground surface of a shallow anchor is similar to a normal distribution curve. The extended diameter of the heave was between 170 and 300 cm, which could be divided into two zones, primary and secondary, based on the failure mode of the ground. As the fixed length of a shallow anchor increased, the extended diameter also increased. The ultimate load of an anchor increased with the free length and, to a greater degree, with the fixed length of an anchor: a fixed length of only 3 m (D = 0.12 m) generated an ultimate load of over 1100 kN.

Published: July 2013

The conventional study of NOx removal is mainly concentrated on the various chemical reactions, but takes no account of the important effect of temperature increase caused by the discharge. In this paper, we present a method whereby the reactive temperature in reaction region can be easily measured without affecting the discharge. By measuring the reactive temperature, it is revealed that the temperature in reaction region is closely related and linearly enhanced with the discharge power, and that the catalysis is not the main reason for the reactive temperature increase. By the investigation on the temperatures effect on the NOx removal, it is found that the NOx removal rate increases with the rise of temperature in reaction region. Therefore, the NOx removal is tightly related with the temperature in reaction region that can be controlled by the discharge intensity under the various ambient temperatures.

Three main fractures exist in coal rock mass, including face cleats, butt cleats, and major fractures. The distribution of cleats and beddings in coal rock mass likes a regular reticular. A geological model was established without considering the major fractures. Young's moduli of fractured coal rock mass were gained through a homogenization method monolayer composite micromechanics analysis method. The relations between volume fraction or Young's moduli of cleat and Young's moduli of coal rock mass were investigated by calculation. Results shown that Youngs moduli of coal rock mass have the same change trends with the increase of volume fraction of cleat in the interval of 0.0018mm of width of cleat. And the width of cleat of 0.5mm is a critical point. Youngs moduli of coal rock mass monotonically increase with the increase of Youngs modulus of cleat in the interval of 0.0010.008GPa. Volume fraction and Young's moduli of cleats have notable effects on Young's moduli of coal rock mass.

In suitable pH value of Walpole buffer solution and in the presence of surfactant Triton X-10 and alcohol, PtCl62- reacts with I- to form PtI62-. By means of the electrostatic and hydrophobic forces, proteins with positive charge, such as human serum albumin (HSA), bovine serum albumin (BSA), human immunoglobulin (IgG) and ovalbumin (OVA), associates with PtI62- to form stable [protein-(PtI6)n]m association particles which cause substantial enhancement of Rayleigh scattering and interface fluorescence. They produce three Rayleigh scattering peaks at 330 nm, 420 nm and 464 nm and a resonance scattering peak at 580 nm, among which the strongest peak is at 464 nm. The four kinds of protein association particle system all exhibit a strong fluorescence peak at 466 nm, while the HSA fluorescence peak at 360 nm was quenched with the formation of the association particle. The cause of the Rayleigh scattering peaks of the association particle system was considered in detail, and the relationship between the Rayleigh scattering and fluorescence of the association particle (the means diameter is about 470 nm) and the fluorescence quenching of HSA was interpreted. Under the optimal experimental conditions, there is a good linear relationship between the scattering intensity (I464 nm) and protein concentration in the range of 0.05~25μg/mL HSA, 0.05~25μg/mL BSA, 0.3~30μg/mL IgG and 0.1~16μg/mL OVA respectively, with a detection limit of 20 ng/mL HSA, 26 ng/mL BSA, 40 ng/mL IgG and 70 ng/mL OVA. This assay has been applied to the determination of the albumin of human serum samples with satisfactory results.

The natural fibre composite materials are nowadays playing a vital role in replacing the conventional and synthetic materials for industrial applications. This paper proposes a natural fiber composite made of Abaca fibre as reinforcing agent with Epoxy resin as the matrix, manufactured using Hand Lay-up method. Glass Fiber Reinforced Plastics (woven rovings) are used to improve the surface finish and impart more strength and stiffness to natural fibers. In this work, the fibers are arranged in alternative layers of abaca in horizontal and vertical orientation. The mechanical properties of the composite are determined by testing the samples for tensile and flexural strength. It is observed that the tensile strength of the composite material is dependent on the strength of the natural fiber and also on the interfacial adhesion between the reinforcement and the matrix. The composite is developed for automobile dashboard/mudguard application. It may also be extended to biomedical, electronics and sports goods manufacturing. It can also be used in marine products due to excellent resistance of abaca to salt water damage since the tensile strength when it is wet.

This paper presents a non-contact measurement solution, which can be used for rapid and accurate measurement of machinery and equipment in a variety of transmission gear wear or breakage situation. This scheme is based on machine vision technology. Through the reverse engineering method we re-build the three-dimensional model of gear s from their two-dimensional image, which can make all the wear and damage morphology of gear surface comprehensively and accurately reappeared. At the same time we give a characterization of the relevant parameters of the wear and tear. Therefore, this method could solve the difficulty in terms of gear wear detection, such as operability, uncertainty and other issues. The application of this method can also provide accurate gear wear data to predict the service life and provide the essential date for the maintenance decision.
