It simulates an elastic material that can dynamically conform to local image features.
This concept composed of two general key components.

The second stage was in the late 1970s to the 1980s, the field of biological engineering, marine development, microelectronics, new energy was the main symbol.
Humans began to further study and develop information resources, and integrate these resources with material and energy to create a variety of informationized, intelligentized and networking information controlled production tools as well as compound production tools composed of a powerful production capacity and more information ingredients by the combination with the industrial machine tools.
In addition to information interactive ways of the handwriting recognition, voice interaction (including speech recognition, speech understanding, speech synthesis) has also become a key technology in human-computer interaction.

Form of social security services, presented the basic auxiliary, human, material and financial resources of the state, collectives and individuals to set up the adoption of social security, community services, family services, casework, group services is rising rapidly in recent years.
Conclusion Computer information management in information suitable for application in the management of social security as a component of the long-term, system- wideprogram works, in the social security sector play an update operation to improve thesystem key utility.

Analysis of the Grain Orientation and Texture of Friction Stir Welded Magnesium Alloy Xu Weiping a,Xing Li a, Ke Lingmin a Aeronautic and Mechanical Engineering College, Nanchang HangKong University, Nanchang 330063,Jiangxi, China a xuweiping1203@126.com Key words: friction stir welding (FSW); OIM; texture; Magnesium Alloy; pole figures Abstract: The grain orientations and microtextures in a friction-stir-welded magnesium alloy AZ80A were analyzed by Orientation Imaging Microscopy (OIM).The results showed that times random of grain orientations in the nugget zone were not strong and orientations were variety.
In this study, the plates were aligned such that the weld traveled along RD of the plate material and penetrated through ND.

Despite of those merits, these instruments still have several limitations such as dependency to samples material reflectivity and slope steepness.
The key idea of the median filter is to run through the data point by point, replacing each data point with the median of neighbouring data points.

The PCB was fabricated by FR4 material with 20 layers, it’s thickness was 3.5mm.
Fig.8 The SFP + optimal simulation results Fig.9 The SFP + optimal lab measure results Summary As the SFP + data rate has increased to 10 Gbps, SI has become the key factor to measure the success or failure of the PCB design.

Bridge Structural Safety Assessment Technology Based On Statistic Analysis SIMENG LIU1 ,a, FANGPING LIU1,b LU LIU1 ,c 1 ChongQing JiaoTong University, Chongqing, 400074, China a5537846@qq.com2, b115090140@qq.com, c86929431@qq.com Key Words: Bridge, Safety Assessment, Statistic Analysis, Controlling Figure Abstract: This paper aims to analyze the statistic rules of the live load effect and the degradation effect and propose some ideas on the bridge structural safety assessment on the condition that both effects closely relate to bridges’ structural performance.
However, if structures are under damage, there will be an irreversible transformation to the parameters reflecting the performance of the material strength.
