Authors: Zhao Shen You , Xu Kai Da , Qiu Su , Jin Wei Qi , Guo Hui , Wang Xia , Jin Kai Jia
Published: February 2014

Non-line-of-sight optical imaging technology is a novel application of imaging technology developed recently, achieving the effective imaging of the corner, basements and other scenes which are difficult to be directly observed by traditional vision with intermediate reflective surface. Smooth building walls, such as tiles and marbles, are typical intermediate reflective surfaces. Because reflecting surface is neither ideal specular reflective nor Lambertian reflective, the reflection characteristics of the intermediate reflective surface have a significant impact on the non-line-of-sight imaging. Based on the test data of the spectral bidirectional reflectance distribution function (BRDF) of common smooth tiles, the surface transfer function and angle spread function of smooth tiles are established according to the Harvey-Shack surface scatter theory in the paper. And the descriptions of the characteristics of specular reflection and forward scattering are implemented. Furthermore, according to the measured BRDF data at a certain wavelength for a certain angle of incidence, we can predict the reflection and scattering distribution at any other wavelengths or for other incident angles. The simulation results indicate that the curves fitted by the model basically are in agreement with the measured data, so that the simulation of the specular reflection and the forward scattering in the model is valid.

Effects of Reynolds Number on Vortex Structure Evolution in a Square Cavity with Two Opposite Moving Lids
Authors: He Shi Hua , Zhang Li Xiang , Hu Ji Min , Yang Hong Xuan
Published: February 2014

The vortex structure of two-dimensional flow in a cavity is calculated using the differential quadrature method. The numerical simulation focuses on investigating the effects of Reynolds number on vortex structure evolution of the flow in a square cavity with two opposite and equal speed moving lids. The streamline patterns and bifurcation diagrams are determined. The numerical results show that the flow in the cavity takes on the streamline pattern of completely symmetric vortex structure when the Reynolds number approaches zero. With the Reynolds number increasing, the sizes and center positions of the sub-vortexes appear to be affected, whereas the saddle point is still located at the cavity center, resulting in a skewed flow pattern in the cavity. It is observed that one large vortex occupies the entire cavity and the shape of the large vortex becomes more circular after a critical value of the Reynolds number is exceeded. If the Reynolds number is increased further, two secondary eddies emerge simultaneously on the upper left corner and the lower right corner near the sidewalls. The center of the large vortex is invariably located at the cavity centre. For different Reynolds numbers, the streamline patterns are symmetric about the cavity center which is always a stagnation point.
Analysis and Application of Multi-Stage Fracture Stimulation in Yanchang Oilfield
Authors: Shen Feng , Chen Xi Yu , Huang Zhi , Qiao Hong Jun
Published: February 2014

The continental shale of Yanchang Formation in Ordos Basin is in complex facies. Being high in mud and low in brittle mineral, the reservoir quality is poor. Therefore multi-stage fracture stimulation has been applied there in horizontal wells. The fracture interval in horizontal well is a critical parameter and it has a great influence on the fracture interaction. Since the fracture interaction can directly determine the extent to which the stimulated reservoir volume (SRV) expands, its most necessary to study the mechanism of the effect. For this, a mathematical model based on elastic mechanics would be given. By using this model, we analyzed the influences on the fracturing work. An analysis of field data from Yanchang Oilfield shows that proper fracture interval can take good advantage of the fracture interaction so as to reduce the horizontal differential principal stress. However, exceeded fracture interaction may raise the fracture pressure. So the effect must be controlled by optimizing the fracture interval. To optimize the fracture interval, the results can be used to instruct the application of multi-stage fracture stimulation.

Designing Parameters of Ion-Implanted Channel Waveguide Using Beam Propagation Method
Authors: Liu Xiang Zhi , Lu Fei , Wu Xiao Ming , Fu Yong
Published: February 2014

Channel waveguide formed by multi-energy O2+ ion implantation with different doses is analyzed at both 633 and 1539 nm. It has been demonstrated that the transverse mode number of waveguide is governed by the practical width of the channel waveguide, which depends on not only the channel width from pattern mask, but the lateral straggling of implanted ions. Beam propagation method (BPM) is employed to simulate the possible propagation transverse mode in the waveguides with different widths. The results at 1539 nm show that the waveguide keeps being a single mode waveguide until the width of channel is greater than 15 μm. At 633 nm, TE20 mode can be obtained even the width of channel is very small, and the TE30 mode begins to appear when the width is greater than 9 μm. These simulation results are in good agreement with the experimental results and the calculated results from Marcatilis method.

Authors: Zhou Bin , Luo Xiao Hui
Published: February 2014

The main method of Infrared and TV image fusion is based on image transform and fusion rule selection. The study implies that the information quantity of Infrared and TV image has significant effect on the result of fusion. This paper proposes one fusion algorithm of infrared and TV image based on image quality evaluation method. The basic idea of the algorithm is that the whole image or the image areas which contains better quantity of information play a leading role in the fusion process. Firstly, algorithm performs the global quality evaluation of infrared image and TV image, and then selects the corresponding fusion strategy according to the quantity of information. The source image has been divided into the high frequency coefficients and low-frequency coefficients using wavelet transform. Second, algorithm selects the rule of coefficients fusion based on the relative image quality of local regions of the image. The algorithm of this paper avoids the interference of low quality image, makes full use of the area of higher information content and achieves the favorable consistency of the fused image. Experiments demonstrate the effectiveness of the algorithm.

Farmland environment is away from power facilities and its information collection lasts long time. These characteristics make the wireless sensor networks in agriculture face the problem of energy constraint. Efficient routing and sleeping algorithm can save energy. Considering the node residual energy and the collection cycle of the destination nodes, this paper improved a WSN routing and sleeping algorithm based on the AODV routing algorithm. This algorithm establishes routing path based on the node residual energy and the node collection cycle. Node sleeping cycle determined after the routing path has been established. By routing path selection and appropriate sleeping cycle this algorithm can reduce overall energy consumption and avoid excessive energy consumption of some individual nodes.

A New Theory of Infinite Series and its Applications in Training Weight Function Neural Networks
Authors: Zhang Dai Yuan
Published: February 2014

A new theory of infinite series is proposed in this paper, some new important theorems for function expansion and infinite series are also proposed. Unlike Taylors expansion, the expansion generated by a function is not the form of polynomials. In general, the performance of convergence is much better than that obtained by Taylor's Series. The new important theorems lay the foundation for the new theory of infinite series and applications. To describe the performance of the new results obtained in this paper, an example given in this paper shows that the region of convergence is much larger than that of Taylors series. The new infinite series can keep some important properties of original functions. Weight function neural networks are also used to training feedforward neural networks based on the new theory proposed in this paper.
