It has not been managed to describe the stage of short cracks development in relation to the material structural data by calculation yet [12], [13].
A well-known fact should be pointed out – in zone 2 curve behavior in logarithmical coordinates receives the character of a right line where it greatly correlates with the experimental data.
In this regard under the terms of the ending and beginning of the diagram first zone (first zone boundary data) let us substitute into (3) speed Vth and condition (2), and Vl0 and Kl0 correspondingly.
It is likely that Vl0 and Vth can correlate through the parametric variable of material structure dg so that FFKD curve will describe experimental data in the best way.
That is congruence Vl0dg=const describes experimental data in the best way, for example, for ferritic-pearlitic steels class.

The association rule mining is a regular method in data mining, which is mainly applied to uncover the interesting association or correlativity among the itemsets of massive data from the transactions database to support medical doctor to accomplish some kinds of decisions.
If the number of transactions for the mass data comparison can be decreased, the more searching operations occur, the more time consumption will be decreased.
Because the larger the data set is, the more transactions can be reduced by the proposed algorithm.

By curve-fitting the results can be presented by a mathematical model, i.e. by an equation allowing the reduction in extrusion at the point of transfer from a state of presence of the pocket to a state of complete die filling, to be computed from the dimensions of the porthole and the weld chamber, for a given billet size and a given bridge geometry.
The flow stress data describing the plastic behavior of the alloy AA6082 has been expressed by a Zener-Hollomon equation presented in [7].
Ternary Extrusion Seam Weld Limiting Diagram In order to cover the variation in the behavior of material flow due to the geometrical changes in the welding chamber, a ternary plot of FE-simulated data is shown in Fig 5.
One advantage of the diagram is that it allows the increased tendency of metal filling into the space behind the bridge to nbe quantified through the reduction in the critical C/2 parameter.
Further statistical data input can increase the predictability of material flow and refine the shaded regions.

The final PSD data was utilized to investigate the amount of the fracture and fouling.
The Hardin breakage index was calculated using the initial and final PSD data to determine the difference in particle size, which reflects the degree of deterioration caused by the applied force.
In this research, the fouling index was calculated using the data obtained from the final PSD graph.

Nowadays we advocate low carbon economy, energy conservation and emission reduction, emphasize the harmonious development of human being and the nature.
The microgrid controlling strategy program judges the realtime status and energy flowing direction of the microgrid through collected data, connects the microgrid to the grid to charge or disconnects it from the grid to run in isolated island, cut off the unimportant loads to relieve loads need or put distributed generations to supply power to loads.
How to confirm the realtime status of microgrid and choose microgrid controlling plan by realtime running data of distributed generations, loads and storage equipment is core of the arithmetic.
Analysis of constructed microgrids in China In recent years because of the promotion of State Grid, also because of the effect of energy conservation, emission reduction and governance haze, kinds of microgrids with functions came out, and capacities of microgrids are distributed from dozens of kW to dozens of MW, related distributed generations are wind power, solar power, water and electricity, terrestrial heat and fuel cell, and structures of the microgrids are different everywhere.

Moreover, it is now easier to acquire data quickly in digital format, making use of low cost microcomputers and widely available.
File storage and retrieval/exhibition of information are just some of the advantages of digital data acquisition.
These techniques can often make it easier some measurements difficult, through of extraction of more information from the available data.
The Savitsky-Golay smoothing technique is based on the least-squares fitting of polynomials to segments of the data.
· Which technique requires less capacity of data storage?

On the other hand, there was a risk of reduction in power for laser beams travelling through the above optical set-up in Fig. 2 b).
Through measurement by power meter at the position of samples to be treated, this reduction of power was estimated to 21 % for fundamentals and 39 % for SHG, respectively.
This system worked on the table top; temporal variation of processing parameters was directly controlled besides data acquisition.

Assuming the basic variables l = 10-10 m-1, T = 365 days, n = 5000 trucks per day on the basis of statistical data of Background materials [8], the annual probability PL of a heavy truck leaving a track can be assessed as PL = n T l = 5000 ´ 365 ´ 10-10 = 1.83 ´ 10-4 (10) The Eurocode EN 1991-1-7 [1] recommends to consider the common probability of collision with a structure as PC = 10-2.
The partial factors g and the reduction factors y recommended in EN 1990 [2] are applied in the design.

‘Tailor’ displays all the optimal processing windows including: the SHT temperature, SHT soaking time, transfer time, die closing force and pre-ageing time.These windowsare computed according to the developed models for the IHTC, air cooling and artificial ageing, and the data input by the user.
The temperature reduction of the blank material should be minimized to maintain sufficient formability, hence the transfer speed must be higher.
