The problem of radial distribution control for burden material as based on the data of radial gas distribution consists in the significant delay of control actions caused by stepwise formation of the proper structure of burden column as the determining factor for gas flow formation process.
This is supported by experimental data obtained from the researches of physical models of throat and on the operating blast furnaces by means of monitoring instruments for surface texture and column structure of burden.
The monitoring of burden surface was carried out on 24-hour basis according to two mutually perpendicular diameters of the throat with automated recording of the most useful data.
The information about the axes of point position for units 1 and 2 is provided by angular sensors 6, 7 and is transmitted to the computing unit 8, the latter determines the incompatibility level for axes of point of the units in the plane to provide its automatic minimization by means of monitoring system 3, it also determines and registers the position data for the checked burden surface.
The algorithm consists in automated search of maximum correlation conditions for two proper arrays of data from the scanners created for one or some geometric profiles of the burden surface.

The results presents satisfied accuracy concerning the literature, while these are valuable data for the oil and gas companies in pipelines construction as well as to control operation issues.
The numerical simulation and estimation of oil pipelines flows can provide useful information and data not only for the transportation of the oil from the source to the refineries but also for the construction of new pipeline network [1].
Major role in oil transferring has the drag reduction, which seems to be numerically calculated by various approaches as in [6-8].
We are looking forward to study the rheological behavior of the crude oil (type: Arabian light) inside T-junction channels providing flow variables and recirculation zones data with satisfied accuracy for various discharge ratio values as well as Reynolds numbers.

The Curie temperature (Tc) is increased besides the slight reduction of dielectric constant (Kc).
Results and discussion The powder analysis by X-ray diffraction (XRD) (Fig. 1) shows the perovskite single structure phase formation according the JCPDS data bank.
This diffraction profile can be adjusted to the Rhombohedral (R3mR - card number #77585) and tetragonal (P4mm - card number #90699) structures, according the ICSD structure data bank.
However, the rhombohedral structure presents a coherent reduction.
The reduction of the weight loss seems to be associated to the barium (II) presence in the ceramic composition.

One possible mechanism for the improved ohmic contact behavior is that the addition of Au and Ti resulted in a reduction barrier height.
Figure 2 shows pre-anneal X-ray mapping images (8 hour acquisitions, including drift correction), a TEM micrograph, and EDX chemical analysis data for the Ti/AlNi/Au sample.
Comparing the two sets of EDX data, it appears that Au has diffused toward the substrate, while the AlNi layer seems displaced 'upward'.
This reduction in barrier height was explained using a model with an enhanced electrical field at the interface due to the small size of the Au particles and the large difference in barrier heights between Ti and Au on SiC [6].

Benefits include the reduction of costs connected to fluid acquisition and disposal, energy saving and reduction of environmental pollution and health hazards in industrial workplaces.
As depth of cut increases, the reduction of maximum temperatures is higher for increasing flow rate from 5 L/min to 15 L/min.
Generally, it was found that use of grinding fluid at the highest flow rate results in a minimum 100 K reduction in maximum temperature for 0.01 mm depth of cut and a maximum of about 200 K reduction for 0.05 mm depth of cut.
For depths of cut 0.01 and 0.03 mm, there is a significant reduction of maximum temperature between cases with 5 L/min and 10 L/min flow rate, of about 120-130 K, and a smaller reduction between cases with 10 L/min and 15 L/min flow rate.

Taking data sampled from full load net generation at 455 MW (net), an analysis was conducted to identify points of improvement in the unit’s air preheating system.
To address the air preheater performance issues, the air heater operation was carefully studied to establish benchmark parameters and baseline data.
A probe was inserted and took readings at each elevation of the data points.
The measurement of temperature at the correct locations in both the inlet and outlet channels can provide adequate data about how air preheaters work efficiently [9].

The studies of microstructure of fragments formed from steel perforated tape have shown the reduction of the structure size and the presence of thin colour oxide layers, which is consistent with the results on nanoindentation.
The nanoindentation data obtained allow not only hardness (H) but also Young’s modulus (E) to be derived.
This may be due to the spread of the heating zone in this depth and the reduction of the initial machining influence.
Average data of hardness (H) and elastic modulus (E) for investigated steel samples with carbon content 0.50% untreated and after laser treatment in Fig.6a and 6b are presented.
Hardness data is consistent with the results of microstructure and elastic modulus data.

At the same time, the economic development of Hebei Province is carried out investigation and analysis, the original data of Hebei Province economic development uses standard data method and normal distribution, to carry out standard processing.
each index factor is different, the system cannot use the original data to calculate, which need to standardized treatment.

The size reduction method had a distinct effect on physical and thermal properties of ginger rhizome tested.
Size reduction technology generally is an emerging technology, which is a useful tool for reduction of particle sizes of various materials into micro and nano scale.
The size reduction due to the grinding process significantly increased the extractability, antioxidant activity, bioactivity and enhanced enzymatic degradation [5-7].
