Authors: Liu Hu Ran
Published: February 2011

This paper researched the forming theory of the cutting tools with helical teeth and complex surfaces. Deduced the nonlinear equations of the movement of NC system to generate such tools, presented the way to find the solution of the equations, calculate the cross section graphics of the teeth profile and made computer simulation for NC machining. In the former research, the position of the work, the point to be machined, and the position of the grinder are undetermined. They must be solved out by a group of mathematical equations, so that the method can be called as analytical method. In this paper, the position of the work, the point to be machined on the work, are deliberately determined before hand, while the position of the grinder is determined by solving a group of mathematical equations. Because of these, this method can be called as the half analytical method, or the half-forming method. The cutting edge A is deliberately turned to special position, some kind like the forming method, while contact point on the cutting edge B is determined by the contact condition, so that this method can be also called as half- forming method. The concept of this method is very clear, the mathematical form is very simple, and the calculation is very easy.

Authors: Liu Hu Ran
Published: February 2011

This paper deduced a new kind of discriminate equation of foot-cut of the gearing, and introduced the application of this new equation. Some times the surface to be machined or the gear profile to be generated could be expressed by the equation as: r̄ =r̄ (u,v) , but some times the surface to be machined or the gear to be generated could only be expressed by the equation as: F ( x,y,z ) = 0 . If the surface or gear profile is expressed by the formal one, we already have several kinds of discriminate equations to deal with the problem of foot cut. But how about the occasions when the surface to be machined can be expressed by the equation as: F ( x,y,z ) = 0 . This paper deduced a new discriminate equation to calculate the foot cut condition and find the way to prevent it.

Published: February 2011

Gabor transform is very suitable for time-frequency analysis and good for filtering non-stationary signals. The threshold of the Gabor transform filter is a key factor for the filter’s effectiveness. A novel threshold based on initial highest inter-cluster distance probability (IH-ICDP) is described in this paper and it can make the filter more efficient. Some experiments have been carried out under several conditions to evaluate the new threshold’s characteristics. The experimental results show that Gabor transform filter with this proposed threshold works better than wavelet transform filter, especially when the signal’s SNR is very low. From the evaluation results, it is possible to consider that the threshold presented is optimal or nearly optimal.

Sediment on the bottom of borehole forms a major part which is often responsible for reducing the bearing capacity of pile. The normal method of measuring sediment thickness by ultrasonic signal is to measure the sound time and intensity of echo signal. This paper presents a novel measurement method by estimating the ultrasonic channel. Wiener filter is applied to estimate the ultrasonic optimal channel under minimum mean square error criteria. Experiments of estimating channel based on Wiener filter have been conducted with given signals and actual ultrasonic detection echo. The influence of noise in the signal has been discussed. The results show that, during signals high SNR, the estimated channel is corresponding to the sharp changes in the actual signal and can be used to determine the sediment thickness.

Authors: Zeng Xian Yang , Wang Xue Tao , Wang Jin Qing
Published: February 2011

: It is estimated that more than 500,000 industrial boilers (mostly stoker-fired) in China consume over 400 million tons of coal per year. Because of low efficiency (only 60-65 percent) of industrial boilers, the energy consumption and pollution emissions from industrial boilers rank second place in China’s industry. On the other hand, China is rich in bamboo resource, and bamboo forest area is more than 5 million hectares, and occupies more than 1/4 of the world’s total. However, the common utilization rate of bamboo timber’s physical processing is below 40% in weight, over 60% of bamboo timber becomes left over when processed. Bamboo wastes, compared with coal fuel, are a very clean and renewable and sustainable energy. Therefore, there is the requirement that coal fired industrial boiler change its fuel into bamboo wastes in China, and some suggestions for bamboo fired boiler are presented in this paper. It is well economy of bamboo fired boiler in the region of China where an abundance of bamboo wastes disposed.

Published: February 2011

With potassium acetate as an intercalation agent, kaolinite-potassium acetate(KAc) intercalation complexes was prepared. Afterwards, nano-kaolinite was successfully made through exfoliated intercalation complexes using power ultrasonic. The intermediate and final products were characterized by X-ray diffraction(XRD), infrared spectroscopy(IR), laser particle size analyzer, and scanning electron microscope (SEM). The results show that intercalation of KAc into kaolinite resulted in a crystal space expansion, from a basal spacing of 7.14Ǻ to 14.20 Ǻ, and the intercalation rate was about 80%. KAc intercalation causes the weakening of interlayer stability.

Authors: Yin Jun Hui , Zheng Jian , Jia Chang Zhi , Xiong Chao
Published: February 2011

A new experimental project was adopted for the special hot-work of pure Cu, which used the execrable condition of high-temperature and high-pressure environment in bore of artillery. Specimen of Cu was prepared from rotating band of sand projectile which had been shot out. Microstructure of Cu after instantaneous extrusion and high speed friction were observed by scanning electron microscopy (SEM). Severe plastic deformation (SPD) and recrystallization phenomena were researched. The analysis results are as follows. At the beginning of SPD, under the instantaneous compression, the surface layer of metal became fibrous tissue with the phenomena of work-hardening. Many oblique strip grains appeared between equiaxed grains and fibrous tissue. With the continuous plastic deformation, temperature of metal improved rapidly under the high speed friction. Recrystallization occurred on the outermost part of fibrous tissue due to heating, so sub-grains gradually became homogeneous equiaxed grains. In addition, SPD had little effect to the inner structure, which is full of equiaxed grains still. All above work could support the research of microstructure of Cu on certain extreme particular environment.

HCC (Hyper-elliptic Curves Cryptosystem) is a typical public key cryptosystem with high efficiency and security. In the paper, we introduced HCC into the designing of e-cash schemes and presented an improved e-cash scheme with formal security analysis. The basic cryptography algorithms in e-cash are based on the complexity of HCDLP (Hyper-elliptic Curves Discrete Logarithm Problem).This designing strategy improves the efficiency for software and hardware application and effectively reinforces the security of e-cash. Dishonest users and outer adversaries can not attack secret parameters with feasible polynomial algorithms. As for scheme analyzing, we presented subliminal channel in signature to attack the IND-CCA2 property of the e-cash scheme, the subliminal channel algorithms can not attack the private keys or secret parameters with polynomial complexity either. Therefore, the scheme proves to be feasible for application with high efficiency and security.

Image fusion is to combine several different source images to form a new image by using a certain method. Recent studies show that among a variety of image fusion algorithms, the wavelet-based method is more effective. In the wavelet-based method, the key technique is the fusion scheme, which can decide the final fused result. This paper presents a novel fusion scheme that integrates the wavelet decomposed coefficients in a quite separate way when fusing images. The method is formed by considering the different physical meanings of the coefficients in both the low frequency and high frequency bands. The fused results were compared with several existing fusion methods and evaluated by three measures of performance. The experimental results can demonstrate that the proposed method can achieve better performance than conventional image fusion methods.

Published: February 2011

A novel porous micro heat sink system is presented for thermal management of high power LEDs, which has high heat transport capability. Numerical model for the micro heat sink is developed to describe liquid flow and heat transfer based on the local thermal equilibrium of porous media, and it is solved with SIMPLE algorithm. The numerical results show that the heated surface temperature of porous micro heat sink is low at high heat fluxes and is much less than the bearable temperature level of LED chips. The heat transfer coefficient of heat sink is very high, and increasing the liquid velocity can enhance the average heat transfer coefficient. The overall pressure loss of heat sink system increases with the increasing the inlet velocity, but the overall pressure drop is much less than the pumping pressure provided by micro pump.

Published: February 2011

The SIFT feature matching can overcome the influence of revolve and scale. It can recognize runway effectively under the complex flight environment, but its computation is heavy. In order to reduce the computation, this paper proposes a new fast method of SIFT feature extraction. This method uses a group of concentric squares to construct the Pyramid-feature-descrptor, calculates each seed vector of the Pyramid-feature-descrptor by using the recursion algorithm, and carries simple sort on the elements of each seed vector to maintain the revolving invariability. The experimental result of identifing the runway indicates that this algorithm not only can increase the speed, but also can identify the runway effectively in revolving and scale.
