Design method of hydraulic system of full hybrid transmission was analyzed. At first, oil volume flow and pressure requirement was confirmed according to the vehicle control strategy. Mechanical gear pump and electric pump were used to supply oil flow for all driving modes. Self-adapted pressure regulation circuit was designed to supply high pressure oil for brake engagement. Structure dimension of valves and cooling orifices was designed by theoretical calculation. Cooling flow can be distributed proportionally among electric motors and planetary gears. © (2014) Trans Tech Publications, Switzerland.

Metal matrix composite (MMC) coatings were fabricated on Ti-6Al-4V titanium alloy by laser cladding. Co42 self-fluxing powder, B4C, SiC and Y2O3 were employed as the cladding materials. Microstructures and the wear properties of the different composite coatings were investigated comparatively. Results showed that the laser cladding coatings were mainly reinforced by CoTi, CoTi2, NiTi, TiC, TiB2, TiB, Cr7C3 and Ti5Si3. The micro-hardness of the cladding coatings were equivalent to 3-4 times the Ti-6Al-4V substrate. Laser cladding coating exhibiting outstanding wear resistance was fabricated with the addition of 20wt.% B4C, 7wt.% SiC and 1wt.% Y2O3. The wear resistance was enhanced by over 10 times compared with the substrate. However, with more SiC addition (14wt.%), a higher micro-hardness was obtained together with poor wear resistance. The wear mechanism of the coatings was discussed by referring to the microstructures and the wear morphologies. © 2015 Elsevier Ltd.

A novel model for privacy-preserving support vector regression (PPSVR for short) on vertically partitioned data is proposed in the paper. The feasibility of the model is proved. Besides, the algorithm for vertically partitioned data is given out. In the privacy preserving data mining, each entity is unwilling to share its group of data or leak the data for various reasons. The proposed PPSVR model is public. But no private data is revealed. And when the PPSVR is calculated at last, the original data does not need to be recovered. Besides, the proposed algorithm has comparable accuracy with that of an ordinary SVR that uses the centralized data set directly. Experiments show that the proposed approach is effective. © 2014 IEEE.

To solve the problem that artificial visual acuity measuring efficiency is low in hospital and school, and waste of resources, this design introduces an intelligent vision test instrument. The instrument is controlled by Embedded system [1,2], including the power supply circuit, a wireless remote control circuit module,LED display circuit, digital display circuit, a voice circuit etc. Beginning of vision test after audio prompt. This time the LED random light under every line in the standard visual acuity chart. The test selects the direction of wireless remote control rocker of up, down, left, rightthrough the E the opening direction on standard visual acuity chart. Data is transmitted to the Embedded system, after data processing, to judge whether he is right and wrong,and then displayed. Intelligent vision testing instrument can achieve the anticipated goal, finally complete the design and production, The overall structure of the circuit device is simple, stable performance, the test results meet the requirements. © (2014) Trans Tech Publications, Switzerland.

To solve the effect that the multi threading task can be achieved by the TFT of color screen, we adopt MSP430F5438 as the main controller, the main equipment of its hardware system was built by the TFT of touch screen, and the task driving function was completed by using buttons and wireless communication module and other peripherals. And we have developed the application program based on UC/OS operating system utility with the kernel structure and characteristics of UC/OS. It can be realized these function, such as digital tube display, TFT display task, multi-tasking, wireless communication, the task driving system, touch screen and low power verification task. The experimental results show that it completely meets the desired design goals, it works reliable and stable. © (2014) Trans Tech Publications, Switzerland.

We study the Painlevé property of the (1+1)-dimensional equations arising from the symmetry reduction for the (2+1)-dimensional ones. Firstly, we derive the similarity reduction of the (2+1)-dimensional potential Calogero - Bogoyavlenskii - Schiff (CBS) equation and Konopelchenko - Dubrovsky (KD) equations with the optimal system of the admitted one-dimensional subalgebras. Secondly, by analyzing the reduced CBS, KD, and Burgers equations with Painlevé test, respectively, we find both the Painlevé integrability, and the number and location of resonance points are invariant, if the similarity variables include all of the independent variables. © 2013 Chinese Physical Society and IOP Publishing Ltd.


Chemical fertilizer is an important agricultural product resource, is food supplier's food. Fertilization scientific and reasonable is an important condition to stabilize output, increase output and benefit. This paper researched the factors affect quantity of chemical fertilizer use correlation and econometric analysis. The result is that chemical fertilizer import quantity and fertilizer quantity of one period of time delay and the price of chemical fertilizer effect fertilization differently. © (2014) Trans Tech Publications, Switzerland.
