This method is realized at consecutive performance of a number of stages: • synthesis of the ANN models which satisfy technical requirements; • definition of structure and ANN topology according to available restrictions, for performance of transformation of information with the highest values of accuracy of functioning; • definition of technical indices of ANN with maximum digit capacity of inputs and a realization platform; • to compose a plan for experiment according to the existing normative documents; • step-by-step reduction of digit capacity of inputs and network elements before achievement of minimum admissible value of accuracy of functioning; • obtaining analytical values of necessary and sufficient digit capacity of ANN; • additional training of ANN with new values of digit capacity of inputs and elements; • visualization of the process and results of the algorithm on the diagrams.
We should remove this noise component before the data will go into the computer complex of the CMM.
The process of determining the necessary and sufficient digit capacity of inputs and neurons is an effective method of eliminating the external and intrinsic noise and non-informative elements for avoiding an unacceptable reduction in the generalization capability of ANN and providing the required accuracy of their functioning. 4.

Edge wrinkle (no edge wave ) The causes and mechanism of edge wrinkle defects 3.1 The causes of edge wrinkle defects For the reasons of edge wrinkle, Zhang Xiaohui [1] pointed out that was because the Strip edge sharp reduction in the flat and thin form, and pointed out that from the edge 50mm of the edge wrinkled steel coil, the edge drop is generally 30 ~ 40 μ m, while the coil which has no edge wrinkle, the edge drop is generally within 10 μ m.
Furthermore, according to the statistics of actual production data, the edge wrinkle defects basic all appeared in the steel whose yield strength is relatively small, and the smaller the yield strength, the higher ratio of the edge wrinkle defects appear, which further proves the above reasoning.
But if the shift of the work roll and is improperly controlled, failed to shift according to the reality of strip edge thickness, resulting in excessive shift of the work roll, will make the thickness of strip edge from thinned into thickened for the relative reduction of the strip edge is too small .

The introduction of filler into polymers has become a trend among researches owing to the excellent enhancement of the resulting composite properties, reduction of the total cost and improvement in the processing characteristic.
The shape fixity however decreased in 5 wt% clay filled TPU in line with the shape recovery data.
As for the reduction in shape fixity, the presence of excess clay may interrupt the crystallization behavior of PCL chains during cooling.

Turbine blade cooling is necessary to avoid reduction of operating life due to oxidation, creep and thermal stress.
Reduction in inlet air temperature results in increase of mass flow rate.

Results from 3- point flexural resistance and water absorption tests showed that the reduction in the particle size of the MOL ashes increased the mechanical resistance to 45 MPa while the water absorption reached 0.8%.
Technological Properties Table 2 shows the data on technological properties determined for the mixtures after firing at 1200ºC.
An approximate reduction of 82% in the water absorption and a 45% increase in the flexural rupture stress is observed with decreasing of the ash granulometry.

They found on average a 4.5% and 4.3% reduction in power and torque respectively.
The equipment is fully compatible with TecQuipment’s Versatile Data Acquisition System (VDAS, available separately).
Using VDAS enables accurate real-time data capture, monitoring and display, calculation and charting of all relevant parameters on a computer (PC available separately) making tests quick and reliable.
A standard 1000ml container was constructed for use as fuel tank and was directly connected to the injector combustion chamber so that precise data will be collected without difficulty and ran for 40 minutes for each sample.
At the start of each test the test engine was operated with base fuel-diesel for about 30 minutes to attain a normal working temperature condition after that base line data were generated and the corresponding results were obtained.

Very little published data has been found dealing with the effect of fire retardant-filled wood-plastic shells on the flammability of coextruded WPCs.
The cone data presented in this paper are the averages of three replicated experiments.
A similar reduction of the THR can been observed with the presence of CNTs in the shell layer.

ISIC defines ICT sector as a set of enterprises conducting production and services activities consisting in seizing, transferring and displaying the data and information electronically [3, p. 81].
Lent, the information project (IT project) is the „temporary form of organization aimed at designing and performing of applications, data banks, organizational solutions, computer accessories, system platforms and other solutions within the computer science” [5, p.
We should emphasize that every organization applies its own term of failure and success of project implementation, whereas the data presented by tSG should be interpreted with reference to established criteria of the project success.
Cui and Olsson analysed the impact of reduction lists on the project implementation success.
The reduction lists were elements determined during the project planning as reducible if other elements of the project appeared more costly than planned [17].
