The key idea is an automated, quick, precise and robust method capable of estimating a set of geometric transformations that resample all images with respect to a reference one, so that the new data will be consistent among themselves.
The central image i of the sequence is assumed as reference and, assuming a relationship xk=Hk,k-1xk-1 between consecutive images, any other is processed using the following criteria: (4) Fig. 1 shows an example of data processing, where a set of 9 bracketed photos was geometrically aligned to generate a final HDR mosaic.
The use of a cascaded matching, where one uses only consecutive image pairs, allows a reduction of CPU time.

（6） （7） (2) When the algorism entered the period of data analysis, we need to calculate the rising of the iteration K[n] and the absolute difference e(n), then the weighing parameter, and in the end amend the value of the P[n]
（8） （9） （10） (3) In the end, we deal with the sampling data u(n), and get the best weighing parameter after numerous iteration like this
The reduction of calculation is a main aspect to improve the algorithm.

The implementation of GB/T 7607-2010 criteria for changing of diesel Engine oil formulate the drop in the rate base value limit of 50% since May 1, 2011. [2] Test Most lubricants contain alkaline additives by the calcium, magnesium and other metal ions with various organic acid surfactant (alkylbenzene sulfonate, alkyl salicylates, etc.) posed. [3] Table 1 tests several data of new lubricating oil for Shenzhen Bus Group Company transport bus.

Fly-ash particle reinforced Al matrix composites have outstanding functional properties such as high specific stiffness, better energy absorption and vibration reduction performances, fine sound absorption capacity, excellent heat-resistant and electromagnetism-shield properties[1,2].
The data show that: Compared with composites without suspending agent, the hardness of fly-ash particle reinforced Al matrix composites amount increase with the content of suspending agent increasing. when the content of suspending agent is 3%, the hardness of the composites reached the maximum (HBS121), compared with composites without suspending agent, the hardness increased by 13.1%.
The grinding ring is made of GCr15 steel, the test load is 300N, the speed is 0.5m / s, the stroke is 90m, each sample was grinded three times and the average test results are shown in Table 2, the data show that: compared with composites without suspending agent, the wear resistance of fly-ash particle reinforced Al matrix composites amount increase with the content of suspending agent increasing. when the content of suspending agent is 3%, the wear resistance of the composites is best, compared with composites without suspending agent, the weight loss decreased by 20.10%.

Apply mathematical morphology is a kind of non-liner edge detection method that can simplify the image data and retain their basic shape feature and proved to be extraordinary than other traditional method of continuity and directionality in edge detection[6,7].
Applying mathematical morphology, we can simplify image data and remove the irrelevant structure, retain the basic shape feature at the same time.

Faced with this situation, most investigators have opted for empirical regression models fitted to measured data.
That is, (8) Only limited experimental data is available from the published literature on which to base a model for this phenomenon.
Given the time between stands and the mean value of temperature and stress, an approximate estimate of the width reduction due to creep for low carbon steel may be written as: (9) (10) Where, c1, c2 and c3 are material class dependent.

However, real ACFM signals always contain much interference noise, thus it is of critical importance for the noise reduction.
Since it is a fully data-driven method, the results will preserve the full nonstationary characteristics of the ACFM signal.
It can be seen that the original ACFM signal may provide misleading defect trace signals due to the complex nature of the crack or the noise pollution from measurement, data collection, experimental error, etc.

Data Analysis A Romanian district heating network that has been built in the 70’s and have to be retrofitted nowadays is analysed in this section.

It is shown that redesign of an old network based on the proposed method leads to 49.7 m H2O reduction of the hydraulic losses, due to sizing of new pipes in accordance with real heat consumption.

A source code programming is developed in the present study while the input data is referred to the previous researchers [8].
The calculated transmission loss is then compared with the published data in order to verify the developed source code.
Based on the analysis of mufflers, both of the baffle thickness and baffle location is found for noise reduction.

Along with the strife for cost reduction in device production, this results in the demand of increasing uniformities of epitaxial layers at larger wafer diameters with low intra-run wafer-to-wafer and run-to-run deviations and higher yields.
The data represent values for our standard epitaxial layers with Fig. 4: Distribution of layer thickness and doping concentration uniformity of more than 2500 100 mm wafers.
These data are derived from over 2500 processed wafers.
