Abstract:The fast wavelet transform (FWT) algorithm in wavelet analysis was introduced in the paper. With quadrature mirror filters (QMF) associated with popular wavelet bases, the fast wavelet decomposition and reconstruction for signals were implemented. Combined with virtual instrument technique, the FWT analysis system for signals was successfully developed. The system can break up signal not only into approximations, which are the high-scale and low-frequency components of the signal, but also into details which are the low-scale and high-frequency components. Especially it can identify singularity signal, which contain some important message of equipment condition and fault, and refine signal from noisy signal, which is corrupted by noise.

Abstract:Pure rare earth metal block La, Ce and Nd was put into the nitrided furnace respectively as a sputter source when typical nitride steel En40B was plasma nitrided. It was found that the incorporation of pure rare earth resulted in the changing of characteristic of glow discharge. Analysis of samples after treatment was performed using related instruments and facilities to examine the effects of treatment on microstructure, micro hardness and element distribution. The results showed that the incorporation of rare earth metals in the glow discharge influenced the diffusion of nitrogen in some degree. Thus the difference of distribution of elements, structure and hardness in the nitrided layer was formed compared with the conventional be plasma nitrided. These significantly affected the response of the investigated steel on plasma nitriding. The extent of influence to plasma nitriding varied with different rare earth.

Abstract:It is an effective way for improving quality of reconstructed images that projection data are optimized in the field of Computerized Tomography (CT). For lowering the fuzziness on projection data caused by lots of factors such as noise and getting the unigue optimal reconstructed image from noisy projection data further more, in this paper, the authors develop a new model named Multicriterion Optimization Model (MOP) for optimizing projection data. The model is structured based on the theories of fuzzy mathematics and decision making, via the method of deducing projection fuzzy exponent function and square error fuzzy exponent function. The experiments for validating the model have been carried out on personal computer (PC). At first, we make simulation collecting in the images presented and add Gauss Noise into the projection data obtained by simulation collecting, Then, complete the image reconstruction from noisy projection data by the solution without optimization and another solution with multicriterion optimization. Finally, compare and analysis the different results about images reconstructed by two different solutions. The experiment results indicate that the MOP in this paper has better consistency with the theory and practice as well as obvious advantage of antinoise ability.

Abstract:This article present the theoretical analysis of gas flow and heat transfer in micro rectangular channels in the regime of velocity slip and temperature jump. The model is built on the assumption that the bottom wall of the channel is in uniform heat flux while the other three walls are adiabatic, and that the flow and heat transfer is of the hydraulic and thermal fully developed laminar flow of the incompressible fluid. Analytic solutions of the cross section distributions of both the velocity and temperature are obtained.The friction and heat transfer performances are discussed. The agreement between analytic solutions and experimental results existed shows that in a definite extension of Knudsen number the traditional Navier Stoks equations and energy equations with the boundary conditions of slip velocity and temperature jump can describe the gaseous flow and heat transfer mechanisms in micro rectangular channels.
