Comparing the results of theoretical and experimental data for force modes of the operation of isothermal backward extrusion of thick-walled pipe blanks points to their satisfactory similarity (difference not exceeding 5% - 10%).
Comparison of theoretical calculation and experimental data for the force modes of operation of isothermal backward extrusion of thick-walled pipe blanks shows their satisfactory agreement (the difference not exceeding 5…10%).
Data on technology of isothermal stamping are supplied in work [10].
Summary Employing the operation of isothermal backward extrusion of thick-walled pipe blanks provides for: a lower labor content in the manufacture of hollow axisymmetric parts with outside and inside thickening nubs (the figure being 30 percent as against mechanical processing); a higher strength-to-density ratio of the item (by 1,2…1,5 times over) with a lower total weight; a higher metal utilization factor – 25 percent as against the existing technological process; a two-fold reduction of the time periods for preparing production of new items.

According to factory datas, the installation assembly pressure of reeds is 20700N.
Condition Load Phenomenon Result 1 25℃ 1250N No pressure reduction, no oil leakage pass 2 25℃ 4000N No pressure reduction, no oil leakage pass Experimental results show that the bushing seal meet type testing of mechanical load test of level I and II requirements.

Experimental data showed 92.44%, 100%, 30.77% and 20% of NLD protection performance data from 0.5 M HCl, 1 M HCl, 3.74 M NH4Cl and 5.61 M NH4Cl solutions are above 70% inhibition value with margin of error of +7.99, +0, +11.22 and +9.72.
Inspection the protection performance data of MR distillate showed progressive decrease in protection performance data at 30%, 60% and 90% concentration.
The mean output shows the average protection performance data with respect to inspection time and distillate concentration.
The SD data shows the degree of variation of the protection performance data from mean values.
The statistical data are shown in Table 4.

The first group includes power supplies, data bus connectors, coupling coils, bus wires and data buses.
However, an additional, fourth, core (data line) is required in the cable.
Communication between modules takes place via the data transmission conductors.
Each data package contains the ID source address, a field with the control sum, an information fields, the destination address and the segment address, and a 24-bit data field.
The next rows describe data decoding and storing in a predefined file.

Introduction In this fast-developing era of big data, time-series data plays a particularly critical role in its application across various fields, such as health care [1], stock markets [2], petroleum [3], and so on.
The data is transmitted in real-time and perpetuated for the long-term.
Consequently, the volume of data is substantial, demanding effective methods to assess the structural condition.
The most common approach with time-series data is using convolutional neural network (CNN).
Data preparation In this work, 11 damage cases are considered [33], labeled from 0 to 10, with different reductions in stiffness for lower chords, vertical chords, diagonal chords and upper chords according to Table 1.

International earth rotation service (IERS) using VLBI, SLR, LLR, GPS, DORIS and other space observation technologies, based on the calculation results of several data analysis centers, defines the ITRF earth reference frame, which is internationally recognized as the reference framework with highest precision and stability.
ITRF reference frame as a three-dimensional, geocentric, dynamic global coordinate reference frame, has become the coordinates benchmark of high-precision GPS measurement and data analysis.
Indirect method to measure ITRF frame coordinates Due to be covered or multipath effect, the ground points cannot directly observe by GPS, or the control points used for reduction are visibility for some special reason.
Based on the GPS geodetic height, change the ground survey data to the corresponding projective plane and calculate plane position of undetermined points using the control survey adjustment software (such as COSA). 5.
Study of United Method of Coordinate Datum for Precision GPS Survey[J].

Through the investigation into composition of major shallow foundation soil mass and the correlation of mechanical indicators in this study, the regression equation of mechanical indicators of the features of local foundation soil mass and the data of in situ testing was obtained.
For the multistory building with 5 to 8 stories and the frame-structured building with load of 1200-2500kN on the signal pile, the driven cast-in-place pile and flat belled-out pile were usually adopted; in such practice, silt of Layer ④2 adopted as bearing layer of pile showed better economic efficiency than that of Layer ⑥, with reduction in construction difficulty and the construction period.

We present a model that qualitatively describes the experimentally obtained data.
This leads to a redistribution of negative charge within the SCR from x < xT to xQW instead of a reduction of negative charge.

This basic but critical and important data have caused interests in the relevant industry in Australia.
The addition of hollow spheres to fiberglass reinforced plastics (FRP), epoxy, compounds, and urethane castings can provide weight reduction cost, savings and improved impact resistance.

The FMBTES method is verified by data simulation of Shaanxi Province Huangling Jianzhuang coal mine, which is large dip angle section of the four sections type belt conveyor system, belt length is 1200m.
The method comprises the following steps (1) The change regular of the start process pull force is found for belt conveyor According to the power equal to pull force multiplied by the rated speed, formula (11) is given (11) Where is pull force of the formula (4) , the line speed is , here, r is the radius of the driving roller, is the reduction rate of the driving motor, then formula (12) can be obtained as follows： (12) Here is synthesized coefficient.
