Then the signal is imported to the processor for data preprocessing including image data rearrangement, synchronous signal extraction and other operations.
After that, the image data will be stored in the SRAM1 by the input buffer control module.
Then the Nios II CPU starts to read the data stored in SRAM1 to transform 14-bit image data into 8-bit image data, at the same time the CPU starts to implement real-time image enhancement in order to improve the quality of the image, then stores the results in SRAM2.
The signal preprocessing algorithm dealing with a mass of data requires a high-speed processing capability.
In this figure, CLK, Reset and INT signals are inputs, while Dvalid, the sign of valid data, and Dout, image data bank, are outputs.

3DOMS is adopted to acquire their surface data, the digital point cloud data of one single vision
within 10s, automatically registering complete point cloud by rotary platform, so that the efficiency
of process inspection and final quality control of the work pieces of complicated surfaces are
improved.
Then automatically register the both data, shown in Fig.8e.
All the data are registered together, and the result is shown in Fig.8f.
Remove the noise from the result and we get the whole cloud data, as shown in Fig.8g.
Export CSV and Unicode data for use in other applications such as SPC, shown in Fig.16.

That is only 17 percent reduction.
According to the Selberg formula [5], the critical wind velocity of multi-tower suspension bridge also becomes to decline with the reduction of frequency of torsional and vertical bending mode.
Cable tension still increases gradually, but anti-slides safety coefficient shows much amplitude reduction.

A minimal genome can be achieved via top-down reduction of bacterial genomes in vivo [1], for which efficient genetic modification strategies for large-scale marker-free manipulation of genome fragments are essential.
After above-mentioned verification (data not shown), one isolate was designated BSΔupp strain.
It is, therefore, more convenient to achieve genome reduction via top-down reduction.

On the basis of acquired tests data, a finite element model was set up shown in Fig. 2.
The stamping depth here is larger and material flows more quickly than in other position, that is the main reason for the thickness reduction.
Stress concentration produced at the sharp corner zone A for its more complex shape, where the reduction is more serious according the simulation above.
In this simulation, the maximum reduction ratio is 21% for the minimum thickness of 1.58 mm, that meets the stamping thickness requirement, no fracture would be produced.

Decreasing of building energy consumption will play a decisive role on energy conservation and emissions reduction of the whole society.
Implementing restrictive policy and incentive policy should also be carry out in our country, that is, adopting mandatory measures such as ban to put into use for the architecture that not reach the energy-saving design standard and adopting measures such as tax exemptions and reductions, soft loan, the financial subsidies to encourage the green architecture that reach or even exceed the energy-saving design standard.
The project with an annual generating capacity is approximately twelve thousand degrees, the annual savings of standard coal is about 6.23 tons, and the annual emission reduction of CO2 is about 22.1 tons Seasonal storage: Seasonal storage technology make the use of radiation plate heat collecting in summer and cold quantity collecting in winter.
Besides, through the research of the current situation of Dongying City green building development, integrated all aspects of content and data analysis to get concrete situation and trend of green building development.

The phase purity and crystal structure of samples were further analyzed using Rietveld refinement of XRD measured data using the GSAS-EXPGUI software.
Ga doping influenced the reduction in FM phase at low temperature region and the reduction in TC value.
We suggested that the substitution of Ga disturbed the spin alignment of the samples which lead to the reduction of FM phase region.

Along with the task of energy conservation and emission reduction increasing gradually, the building industry as the large energy consumption user and its energy conservation and emission reduction has got the high attention.
Relevant data has shown that the existing building area in our country has already reached about 50 billion square meters1.
Consequently, the housing design and standard are not advanced enough, and some qualifications such as the carbon reduction are relatively backward comparing with the developed countries.

The biooxidation caused an increase in the total copper recovery to 97%, i.e. 2.5% increase compared to ferric leaching and reduction of its content in the residue by two times (to 1.49%).
The maximal rates of ferric iron reduction and copper leaching were observed during the first hour of the process, and then they were sharply decreased to remain constant the rest of time.
