Such a transformation is called the fourth industrial revolution or “Industry 4.0”, which includes such advanced technologies as: big data, Internet of things, virtual and augmented reality, 3D printing, quantum computing and others.
Conclusion As a result of the work done, the following patterns were found when using vibration oscillations at a frequency of 400 Hz: - a significant decrease in porosity; - grinding the sample structure; - increase in hardness; - reduction of anisotropy of properties depending on the direction.

Conclusion
In this short paper we have paid attention to one possible way of reduction of energy consumption in the case of building with controlled interior temperature, using the original intuitive modular computational simulation tool.

On the base of real stress-strain curve the material data approximation was set.
The full elimination of plastic deformations is only possible by respective reduction of the internal pressure for the existing vessel geometry.
Certain calculations performed for pressure vessels with flat endplates with curved, but non-circular shapes give further reduction of the stress concentration.

Dehydrogenase activity was determined by reduction of 2,3,5-triphenyltetrazolium chloride (TTC). 5 ml of TTC (4 g/l) and 2 ml of glucose solution (0.1 M) were added to 5 ml of activated sludge in a 100 ml conical flask; the mixture was shaken at 125 rpm and room temperature for 20 min and then incubated at 37 ˚C for 12 h.
The data presented in the text and figure was the mean values.
Concerning about the aerobic biological treatment, the nitrate reduction was retarded so as to decrease the effect of urease action in the nitrogen cycle process.

Introduction
High manganese sheet steels offer a combination of high strength and large ductility, which can attributed to the high strain hardening rate of these steels [[1],[2]], making high-Mn steels strong candidates for automotive mass reduction applications.
Their calculations for Fe-22Mn-C alloys also predicted a SFE reduction with lower alloy carbon content.
HKL software was used to operate and control the EBSD analyses, acquire and collect data and as conduct analyses.

The NIST08 mass spectral data library was used for identifying chromatographic peaks.
The reduction of TPO yield and the increase of BPO and gas yield after 50wt.% MR show that organic vapor devolatilized from SS may be catalysis cracked to form hydrophilic or uncondenserable components.
Consequently, the reduction of steroids and aliphatics content may cause by intensified dehydration and deoxygenation reactions catalyzed by SSC.

Then, a large reduction in section modulus can be expected.
Basic data: Glulam GL24h width at t= 0 200 mm crack development: 3 yrs < t < 13 yrs width at t=13 years 120 mm depth 800 mm shear strength: 4.5 N/mm2 Load carrying capacity in shear: 480 kN (t=0) Load scenario 1: 30% constant load Load scenario 2: 15% constant + 20% snow load, 1 month per year.
Then, the load carrying capacity in shear of the cross section would reduce similarly to the width reduction during cracking.

Due to the thermodynamic stability of CO2 molecule, efficient and selective catalysts are required for reduction on the activation energy of the reactions.
This behavior is similar to data found in the literature [22].
Although there is also a reduction of the selectivity for PC, this was the best result obtained with SnTNT nanostructure.
