Porous SiC ceramics are fabricated by various methods including partial sintering [7], carbothermal reduction [8-9], replication or pyrolysis of polymeric sponge [10-12], reaction bonding [13] etc.
The mechanical property data of oxide bonded porous SiC ceramic samples of the present work are thus comparable to those mentioned by many researchers. 5.

From the data of 2009, ICT consumes about 8% of the total electricity all over the world.
Although IP centered data services have been widely accepted as the dominant service in future, there is still large numbers of traditional Time Division Multiplexing (TDM) service and fixed rate leased lines.
Since the typical transmission distance in MAN is relatively short and the same is the transmission data rate, the major energy consumption comes from the optical transceiver.
In an OBS networks, the OBS control information called Burst Head Packet (BHP) is sent separately in a reserved optical wavelength before the Burst Data Packet (BDP) transmission.
In optical networks, there are dozens or hundreds of wavelengths which carrying high speed data up to 10 or 40 Gbit/s.

In particular, the average highest daily concentrations of Beijing could be between 200μg/m3 and 260.3μg/m3 according to the monitor data in summer of 2006, which is much higher than the WHO guide criterion [2].
In basic scene(business as usual), the average highest daily concentrations of Beijing city, surrounding counties, Tianjing, Langfang and Baoding are set to be 250μg/m3, 126μg/m3 , 213μg/m3 , 213μg/m3 and 213μg/m3 according to the monitor data in 2006 and 2007.
The exposed population in case study area is considered as the data of resident population in the end of 2009.
The baseline incidence data of bronchitis and mortality rate are collected from Health Statistics Yearbook of China in 2010 .Asthma is not included to valuation in this paper for data limitation.
The concentration and reduction scope in six targets are assumed, the reduction should be achieved by related pollution (VOC and NOX) abatement of pollution sources in Beijing and its surrounding areas.

This paper analysis the data of 44 counties in 2010 and a method to evaluate the comprehensive strength is given.
Data Source The Data source is from the Yearbook of Statistics Liaoning 2011, the statistical indicators of 44 Counties of Liaoning Province In 2010 (County Economy in the county).
Therefore, using the method of principal component analysis, index "reduction" process, but should pay attention to the following questions: First, corresponding with the evaluation target, through the necessary "pretreatment" make "negative index" index showed a "index", the index value is greater, the stronger.
Among them, xij is the value of original data; xij’ is the value after the standardization; min{xij} is the minimum value of the original value in the column; max{xij} is the original value maximum value in the column.
The comprehensive strength of 44 counties in Liaoning is analysis based on the data in 2010.

Analysis of the creep data over the temperature range
1073-1123 K reveals two distinct regions of creep behavior present in this material.
Unfortunately, the large amount experimental data collected on mechanical properties showed limited toughness at ambious temperature and poor strength at high temperatures.
In order to obtain dense materials, these cast ingots were extruded at 1373K~1473K using a 16:1 reduction in area followed by air cooling.
Fig.1 Tensile true creep rate vs. true strain curves for NiAl-25Cr alloy (a) 1073 K, (b) 1123 K under initial stresses varying from 20 to 50MPa Since the data were obtained under constant load conditions, the creep rate increases gradually with increasing strain under quasi-steady-state conditions due to the fact that the specimen cross-sectional area continues to decrease and the true stress continues to increase during deformation.
The creep data from Fig.1 are plotted as strain rate versus stress on double logarithmic scales and are given in Fig.2.

The successful forming of the parts demonstrated the feasibility of the tailored thickness blank approach that can enable the reduction in component weight.
Among these innovations, tailored blanks offer significant weight reductions and enhanced mechanical properties.
The data obtained from these tests was then utilized to develop a material model that could simulate the process of forming tailored blanks.
The experimental data gathered from these tests was then used to develop and validate a material model capable of simulating the forming process of tailored blanks using finite element analysis
These results were also compared to the initial data collected from the machined blanks before forming.

Mat lab experiments show that stack filter can greatly reduce the time of clears image noise, and it performs better than median filters on noise reduction while retaining edges of an image.
Images are often corrupted by noise because either data acquisition or data transmission.
Therefore, the problem of recovering an original image from noisy data has received ever increasing attention in recent years.
Table 1 Results Comparison of different image processing standard median filter stack filter(threshold decomposition) 3×3 5×5 7×7 7×7 1 2 4 6 PSNR 9.0912 6.9821 2.6192 1.5739 10.6499 5.1610 8.6864 10.4697 The data may see from the table, in stack-up value filter's denoising effect compared to standard in value filter's effect fairly good somewhat, but simultaneously also sees, is not the threshold value is bigger is better, therefore when uses the stack-up filter must choose the most superior threshold value to carry on the decomposition, the denoising effect will be only then better.
