Wide band and low dispersion slow light in optofluidic infiltrated photonic crystal waveguide has been theoretically demonstrated. By adjusting the refractive indices of infiltrated optofluidic in the nearest four rows of air holes beside the defect waveguide and tuning the radius of bulk holes, the group index and bandwidth can be enlarged effectively at the same time. Considering the restricted...
In order to make further improvement for the effectiveness on motion estimation and its compensation of mesh, this paper proposes an algorithm with mesh motion estimation of Delaunay Triangle (DT), based on redundant wavelet transform (RDWT). Firstly, the feature points and potential motion areas (PMA) of mesh are extracted from the domain of RDWT, and the motion intensity degree of image blocks can...
An object detection method which can be used in indoor and outdoor monitoring was proposed in this paper. Improving shortcomings and disadvantages of moving object extraction in traditional inter-frame difference method, it puts forward a moving object recognition algorithm based on redundant wavelet transform, namely, extraction of feature points in redundant wavelet domain to generate a delaunay...
Using survey data, it is analyzed the path relationship between human capital and technological innovation. Then the regulatory model is build with organizational culture as regulatory factor in human capital to exploratory innovation and exploitative innovation which is tested by regression analysis. Studies have shown that human capital has positive impact on two types of technological innovation...
A design scheme of information system is demonstrated based on Struts, Spring and Hibernate, which implemented the three layer software architecture. And then the Simplified method is introduced to implement object persistence layer using Myeclipse; Finally, Spring Framework is put forward to simplify data operations on persistent object. The experiment result demonstrates the scheme simplifies data...
In this paper, dividend payments of a risk model with reservoir is considered. We modify the compound Poisson surplus model for an insurer by including liquid reserves and interest on the surplus. Integro-differential equations and boundary conditions satisfied by the moment generating function and higher moments of the expected discounted aggregate dividend payments and Gerber-Shiu function are obtained.
In this paper, the theory of human capital and technological innovation is introduced firstly. Then, the promoting role of human capital in technological innovation is discussed. Thirdly, we analyze the influencing factors of human capital on degree of technological innovation. Finally, the directions of future research are discussed.
The oxygen sensor of electronic fuel injection engine is one of important sensors in electronic control gasoline injection system. The oxygen sensor can do the role of monitoring and instruction to internal combustion in engine cylinder. This paper verify oxygen sensor in the diagnosis of the role of EFI engine failure through measuring engine-related parameters and waveforms, such as oxygen sensor...
Local Binary Pattern (LBP) is a kind of discriminative texture descriptor for characterization of face patterns. However, the value of LBP operator is greatly changed under non-monotonic intensity transformations. As a result, the recognition performance of LBP descriptor for face images with significant illumination variations is severely dropped. In this paper, a novel illumination-invariant face...
Recently a network-constraint regression model[1] is proposed to incorporate the prior biological knowledge to perform regression and variable selection. In their method, a l1-norm of the coefficients is defined to impose sparse, meanwhile a Laplacian operation on the biological graph is designed to encourage smoothness of the coefficients along the network. However the grouping effect of their Laplacian...
According to the characteristics of infrared image, a method of nonsubsampled pyramid based adaptive anisotropic diffusion filtering for infrared image denoising is proposed. First, nonsubsampled pyramid is used to decompose noisy image into lowpass subband and multi-scale bandpass subbands. Adaptive anisotropic diffusion filtering is performed in all bandpass nonsubsampled pyramid layer aiming at...
Nowadays wood-based panels are widely used in furniture manufacture and interior decoration. They would release formaldehyde during the service for most of them being bonded with the formaldehyde-based adhesive. The formaldehyde does a great harm to people's health. Measurements should be taken to lower the formaldehyde emission. Several methods were introduced in this paper to solve the problem....
The dynamic thermal mechanical properties of Bamboo fiber(BF)/Polylactic Acid(PLA) composites were studied by the thermal dynamic mechanical analyzer (DMA). The results showed that E' and tanδ were affected by mass fraction of BF and coupling agent. Because interfacial compatibility between BF and PLA was poor, the dynamic thermal mechanical properties of composites were bad when coupling agent was...
Cement-bonded straw fiber board made from straw fiber and cement was prepared by semi-dry processing technology to investigate the effect of alkali treatment on the mechanical properties of the board. Results indicated that, board fabricated with 1% alkali solution treated fiber showed maximum improvement in mechanical properties. After alkali treatment, hemi-celluloses of straw fiber were removed,...
Binderless particleboard from kenaf core was prepared by steam-injection hot pressing technology and conventional hot pressing technology respectively, and temperature variations of mat core layer was tested by thermocouple during hot-pressing process, density profile of binderless particleboard was tested by isotopic density tester, the effect of two different hot-pressing technology on mechanical...
Bamboo wood especially the Phyllostachyspubescens is extremely abundant in our country, however, the high moisture content and easy to mildew and decay has limits it widely application in solid material. In this study, a novel carbonization with low temperature and non-smoke is introduced, and whole factor analysis method and variance analysis are used to find a novel and optimized process parameter,...
Wood-based composites is widely used in building and interior decoration field. However, it is easy for wood to get burnt, and abundant toxic smoke generating during the burning process has caused great casualties and property loss. In this study, poplar wood was chosen as test materials, and three fire-retardant were selected, i.e. the inorganic X type fire-retardant and the organic fire-retardant...
This paper proposes a novel grayscale image compression approach using the binary wavelet transform (BWT) and context-based arithmetic coding, namely the context-based binary wavelet transform coding algorithm (CBWTC). In our CBWTC, in order to alleviate the degradation of predictability caused by the BWT and eliminate the correlation within the same level subbands, three highpass wavelet coefficients...
We report multifactorial analysis of candidate mechanisms of Alzheimer's disease utilizing high content analysis, gene expression microarray, and linear regression model to integrate neuronal imaging data with hippocampal gene expression data. Our analysis led to the identification of several genes that may contribute to different image traits or phenotypes in the amyloid-beta (Abeta) injured neurons...
