The disadvantage of this technology is in that the conditions of ingot crystallization predetermine its heterogeneity in composition and structural state - along walls of the mold the fine crystalline structure is formed due to the maximum overcooling, and in the zones under the conditions of less overcooling there is a possibility of their intense growth up to larger sizes due to reduction of amounts of crystallization grains.
In the formation of solidificated mass of the melt the atomization process significantly slowed, and the obtained powder particles have a heterogeneous composition, microstructure and the shape, leading to reduction of quality characteristics of the obtained powder and its mechanical properties.
The results obtained on the basis of experimental data are shown in Fig. 2, from which it follows that for each angular speed of the electrode rotation, under otherwise equal process conditions, there is a maximum amount of powder of a certain size.
In addition, such system provides increased productivity of the installation and stability of the tungsten carbide atomization process, reduction of gas saturation of the billets, that increases the stability of the parameters of the process ofbillets atomizatiom; - availabilityin the design of rotation mechanism of the special holder for atomization of billet, provides reduction of dynamic loads on the billetduring it ratation at high speed, and ultimately the probability of its destruction during atomization; - there is a possibility of maintenance of the plasmatron without depressurization of the operating chamber, which minimizes the time on its maintenance service, promotes ecological compatibility, performance of the powder atomization process and economic efficiency of the atomization process; - for protection of mechanisms of rotation and movement of the billet from abrasionweraunder the action of the solid powder particles, and to improve the operating resource of the mechanisms
In addition, such original design provides considerable reduction of temperature of operation of moving units and mechanisms, which also significantly increases their operational life; - to achieve high performance and automation of the atomization process the installation uses a special cassette for accumulation of billets providing stable uninterrupted supply of billets for atomization in an amount up to 100 items, and non-stop operation of the installation within several 8-hour shifts (a few working days).

However, available data for 2011 give a global cement production of already 3.6 billion tons [12].
A generalized use of plasticizing chemical admixtures leads to a further cement reduction (Tool 3).
Mehta and Meryman [9] state that the combined use of tools 1 and 3 may give a reduction of 30 % in cement consumption.
In total the reduction might become about (0.7 x (2800 x 0.6 x 0.8) = ) 941) million tons/year, being the 1990 emission rate.
Restoration providing opportunities for sustainability Because of the importance of environmental protection, energy saving and reduction of demolition waste within the vision of sustainability, restoration has become an important issue.

In case of pipe fittings in fig.4, the weight reduction of over 50% was obtained by thinning the thickness to the minimum.
In this system, the casting simulation of TCSSM for molten iron flow, solidification and, deformation of casting is ran using 3-D data of parts figures, and the gating design and lost-form mold design are executed according to the calculated results.
The obtained result was approximately 10% cost reduction.
Over 60% reduction was achieved for both respects.
CONCLUSION TCSSM is the superior casting process comparing with conventional sand casting process in many aspects of energy and resource savings, process simplification, quality improvement, cost reduction.

And it is reported that in the current data centers, more than 80% of the data stored were redundant, adding nearly 10 times cost of non-redundant data to process [2], posing an urgent need for data deduplication, which could eliminate duplicated data and improve the storage space utilization.
Deduplication is an effective method of data compression.
Thirdly, with the reduction of write traffic and the times of garbage collection, the time of erasing Flash memory decreases, resulting in longer lifespan and better reliability of SSD, because it is known to all that the more the write data is, the shorter the lifespan and the higher the bit error rate is.
In addition, read performance keeps steady, since the process of reading data does not change.

Exemplary data illustrate its operational capabilities in transient vibration measurement and non-destructive testing.
Full-field data were captured from 0 to 109 ms comprising 65536 samples for the 12 by 12 array.
The full data record on the other hand provides a comprehensive representation of the plate dynamics as the excitation approaches and passes through the various resonant modes of the plate.
For point scanning sensors this approach would further compound the already lengthy data acquisition process.
These data indicate potential damage due to disbond or delamination of the underlying composite structure and would typically warrant further inspection.

These are intended for access to data, heterogeneous content and to interoperate information systems [4, 5].
This information is data and metadata, which allows the interpretation of the descriptions of the web services.
It can be used to specify semantic types of the input and output data of web service and its functionality.
It allows the simulation of multiple data centers.

The development of production and the relative availability of cement led to a significant reduction in demand for many clinker-free, including lime (Portland) binders.
Electron microscopic photo-aluminosilicate (with a filler in the form of a fine-milled zeolite-composite with a filler) Portland aluminosilicate composite 1-ground zeolite tuff (with a filler in the form of a thin-ground fight of a ceramic brick), 2-ground fight of a ceramic brick IR spectroscopy data (Fig. 7), as well as radiographic data (Fig. 8) indicated the formation of the composite relations between the portlandite crystals and between the crystals of portlandite and aluminosilicate component.
The use of such aluminosilicate raw material, which contains metastable minerals of imperfect structure leads to the formation of new compounds and new connections between them and the Portland matrix, which is confirmed by the data of x, XRF, SEM. 4.
The effectiveness of the contact-condensation technology, which provides a reduction in energy consumption to achieve a unit of strength by 2-3 times in comparison with cement technology and by 20-30% in comparison with autoclave technology, is proved.

Therefore, the system identification process will need to base itself on output-only data.
These data can then be compared to or even decomposed into the laboratory modal results [1].
Fig. 5: The measurement system data flow of PMS turret.
After the completion of the tests, the collected data is reduced and grouped into test phases.
The experimental data are processed and analyzed using the LMS test lab [5].

The gained data can be used for material modelling in ABAQUS using Mohr-Coulomb or Drucker-Prager model.
A consistent use of these materials with more than 90% in the Ultralight Steel Auto Body (ULSAB) led to weight reductions of about 25% and a gain in rigidity of 80% [3].
Shear test For the numerical simulation of the behaviour of the beads it is necessary to gain data of critical shear stresses under compression leading to a plastic deformation of the bulk case.
The measured data shows a constant compression stress for the whole test and an almost linear increase in punch displacement.
MS1200 friction stress Summary Using experimental setups of soil engineering and granular material science modified for high pressures up to 100 N/mm² it is possible to gain data for numerical simulation of the behaviour of ceramics beads which are intended to be uses as medium for hydroforming at elevated temperatures up to 600 °C.

So the optimization model is shown as follows. 1) Target function The objective function of neutral current control can be expressed as Min (4) Similarly, the objective function of distribution transformer losses reduction can be shown as Min (5) 2) Constraints a) device capacity The device capacity is limited, so the regulation must satisfy the actual situation of device (6) b) reactive control When reactive component is necessary to avoid overcompensation and make the value of reactive power tend to zero (7) c) the neutral current control The weight coefficient is decided to achieve different target based on the neutral current before regulation
