With the development of information network technology and the decline of the cost of electronic computers and other related equipment, the teaching forms and teaching methods of College English teaching have been greatly changed. Multimedia information technology assisted teaching mode through the image, audio and video data show that teachers and students can better into teaching, can effectively promote college English teaching quality improve. In this paper, through the comprehensive use of literature, survey, etc., through the a city 10 ordinary universities to carry out a questionnaire survey, draw the conclusion: (1) The overall level of multimedia information technology in College English teaching is low. (2) The way and method of using multimedia information technology to assist college English teachers. (3) The importance of modern education technology in Colleges and universities is insufficient, and the information quality of both teachers and students need to be improved.

In consideration of the problem in traditional aero-engine fault diagnosis, a new algorithm was proposed, which does not rely on engine math model nor numerous data samples. This method based on grey relationship degree theory, engine gas path fault symptoms shifts were needed first, and then the relationship degree was calculated between ambiguous faults and specific faults to achieve the fault diagnosis. Finally, the CFM56-3 fault example validates the effectiveness and feasibility of this method. © 2011 Published by Elsevier Ltd.

Using the complete discrimination system for polynomial method, we study the (2+1)-dimensional Davey-Stewartson equation and obtain the classifications of all its envelope traveling wave solutions. This is very convenient in practice to give the corresponding solutions for the concrete parameters. © 2010 World Scientific Publishing Company.

A novel dual fuzzy neural network to civil aviation aircraft disturbance landing control is presented in this paper. Conventional automatic landing system (ALS) can provide a smooth landing, which is essential to the comfort of passengers. However, these systems work only within a specified operational safety envelope. When the conditions are beyond the envelope, such as turbulence or wind shear, they often cannot be used. The objective of this paper is to investigate the use of dual fuzzy neural network in ALS and to make that system more intelligent. Firstly the dual fuzzy neural network is trained from available flight data and then that trained neural network controls the landing, roll, pitch and altitude hold of the airplane. Current flight control law is adopted in the intelligent controller design. Tracking performance and robustness are demonstrated through software simulations. The neural network control has been implemented in MATLAB and the data for training have been taken from Flight Gear Simulator. Simulated results show that control for different flight phases is successful and the dual fuzzy neural network controllers provide the robustness to system parameter variation. © 2012 Springer-Verlag Berlin Heidelberg.

The microstructure and corrosion behavior of electroless Ni-P alloy plating on 6061 aluminum alloys substrate in an alkaline plating bath with sodium hypophosphite as reducing agent were investigated. The effects of bath temperature on the plating rate, compositions, and microstructure of the electroless Ni-P deposits were studied. The results showed that the deposition rate and the P content of the electroless Ni-P deposits increased with the rise of the bath temperature. Scanning electron microscopy (SEM) of the deposits showed nodular structure for binary deposits. X-ray diffraction patterns of all the deposits revealed a single and broad peak which indicated the amorphous structure of the deposits. Corrosion resistance of the Ni-P coatings was evaluated by potentiodynamic polarization. The results indicated that electroless Ni-P plating could obviously improve the corrosion resistance of 6061 aluminum alloy. © 2010 ACA and OCCA.

In 3-D surface measurement based on continuous wavelet transform (CWT), the choice of wavelet function plays a key role. Mexican hat wavelet, Morlet wavelet, DOG wavelet and Gabor wavelet generate from Gauss wavelet function, and Mexican hat wavelet is the second derivative of Gauss wavelet function. Because of few discussion about real Gauss wavelet, it can be used in 3-D measurement and will be deeply discussed in this paper. Based on theoretical analysis about the principle of phase reconstruction using real wavelet function via Hilbert transform, we can get the phase information from deformed grating image using real wavelet function. The simulation and experiment of 3D surface measurement based on real Gauss wavelet are carried out.

Material and design affects the performance of shoes. In this study, according to different materials and designs, plantar pressures of Kappa tennis shoes compare to Adidas tennis shoes were tested, Fifteen male volunteered to take part in this student. After collecting and analyzing these data, the findings came to as follows: (1) There were no difference between Kappa tennis shoes and Adidas tennis shoes, (2) there is no safety risk factor in Kappa tennis shoes, and (3) the testing results showed that the damping part of first metatarsus (M5) of Kappa shoes, arch parts (M2 and M4) and supporting value should be improved. © (2014) Trans Tech Publications, Switzerland.

To suppress the counterintuitive and invalid conclusions produced by the D-S theory of evidence with highly conflicting evidence, a modified evidence approach based on the improvement of both evidence sources and combination rules is proposed. Such a method comprehensively utilizes the advantages of DS theory and additive strategy. First, reliability measurements are applied to generate the weights of evidence sources based on the Pearson correlation coefficient. After that, the conflicting coefficient is apportioned to focal elements based on the weights, which gives reasonable corrections for the fused results. Finally, the improved evidence sources are fused by the modified combination rules, which fully utilize the conflicting information. Examples provided demonstrate the efficiency and rationality of the proposed approach. © 2012 IEEE.

Water-entry impact of air-launched AUV (AL-AUV) is considered as a time-depended strongly nonlinear fluidstructure Interaction phenomenon. Numerical modeling technique of AL-AUV on its initial water-entry impact is given by using the Multi-Material ALE-Lagrange coupling algorithm. The key aim is focused on the numerical modeling approach taken in detail to dealing with water-entry impact. Based upon this, water-entry impact loads and effect of fluid on the impact responses are also specially discussed. Numerical results show that the exact dynamic characteristics can be obtained in effect by modeling the appropriate waterentry numerical model and the right resolve method. It is helpful to the structure design and to analyze the later hydroballistics. © 2012. The authors - Published by Atlantis Press.

There are many reasons for having a lubricant within the engine besides that of reducing friction. However scrupulously clean the engine is maintained, there will always be a small amount of dirt or impurities that find their way inside. That dirt must be removed before it can cause damage to bearings or block small oil passageways. The oil can be used to keep the engine clean by carrying dirt to the oil filter where it is strained out and where it remains until replacement of the filter. The majority of the bearings within the engine are manufactured from steel, a metal which would soon oxidize itself if it were not prevented from doing so by a liberal coating of oil, thus the lubricant will also minimise corrosion inside the engine. © (2014) Trans Tech Publications, Switzerland.
