Note that the pre-application of the epoxy-based binder simplified the process of powder spreading during 3-D printing, due to the reduction of the negative effects of electrostatic agglomeration and dust formation.
The input data for printing had an ISO 7-bit (G-code) format.
When the temperature in the furnace reached 1400 °C and there was a strong reduction in nitrogen consumption, heating was stopped, since the reaction sintering process could be considered completed.

Reduction of the cell gap from 5 μm to 3 μm is only partially responsible for this effect.
This reduction in response times can largely be attributed to the generation of new liquid crystal mixtures.
All measured values for 10 pieces of LCCs were within data given in the Table 2.

Introduction
Activation of liquid phase before mixing concrete ingredients with water is considered to be an important strategic direction aimed at enhancement of strength properties of cement concretes provided the reduction in consumption of material resources.
According to the presented data, if mixing liquid passed through the preliminary mechanic magnetic activation, it could be possible to reduce the amount of additives 3.75-fold for Na2S2O3 and up to 30-fold for CaCl2.
The important distinguishing characteristic of the X-ray diffraction images of the researched specimen is the reduction of Portlandite reflex dn = 4.91 for activated specimens that could be explained by crystallization of a large quantity of other calcium compounds, in particular, calcium carbonate.

In the same table, other geometrical data are reported, namely: the spacing
On the contrary, when the number of perforations is low, the increase of the ratio D/s leads to an excessive slenderness of the plate portions included within two adjacent perforations, this entailing a reduction of the ratio Fpinc/Fmax due to the pinching provoked by the development of buckling phenomena.
Also, it has been noted that when the parameter x increases, due to a reduction of the not perforated zone of the panel -this meaning holes closer to the panel edges- the ratio Fpinc/Fmax increases as the number of holes grows.

The measured values were compared with reference data [7, 27, 28] to quantify their validity.
The reference data has been also obtained on the ground as 2.39×10-9 m2s-1 [27] and (2.44±0.02)×10-9 m2s-1 [28].
The dotted line shows the reference data (2.4×10-9 m2s-1) [7, 27, 28].
The gray area shows the uncertainty of the microgravity reference data [7].

The lapped parts have a very good flatness due to
the fact that the active surface of the tool is simultaneously the machining datum surface.
Simultaneous double side grinding (SDSG) is believed to be as effective as lapping in waviness reduction [3].
Every five minutes, the workpieces were removed from the separator and, after cleaning, the height reduction ∆hw was measured.
Average material removal rates for electroplated diamond tool (a) and for all tests (b) The reduction in abrasive properties was expected due to the abrasive wear.

LVDS provides a high-speed data transmission (1.4Gb/s), suppression of common-mode noise and reduction in power consumption for the system [7].BLVDS (Bus LVDS) is an extension of LVDS in multi-point communications, which requires bus arbitration design, stronger drive current (10mA) and better design of impedance match.
The amount of processed data is packaged by the high-speed bus, sent to data processing module.
Therefore, real-time data was transmitted at fixed intervals, and then the remaining cycle time was used to transmit standard TCP/IP data.
Data was sent to process layer bus by the optical interface, as open-source data which other IED had access to.
Design of interface of Highrate Data Sampling System Based on FPGA.
