Considering the growing trend in the field of reduction of building construction energy intensity and reduction of CO2 production a general assumption at development of new thermal insulating plasters is the reduction of thermal conductivity and also reduction of density in mature conditions which results in general saving of raw materials necessary for production of 1m3 of applied plaster.
In case of calculation with newly developed insulating and remedial plaster the measured data were saved in the material database to enable the calculation.
It is obvious from these data that the developed plaster improves behaviour of brickwork when applied from interior side in view of its thermal technical properties and enable vaporisation of possible condensation back to the interior of the construction.

The simplified Bishop method uses GeoSLP1 software to calculate, and the strength reduction finite element method uses ABAQUS 6.10 software to calculate.
When using strength reduction finite element method, elastic modulus of soil is valued as 200MPa, Poisson's ratio is valued as 0.3.
The calculated stability factors using formula (1), formula (2), simplified Bishop method and strength reduction finite element method were recorded as F1, F2, F3 and F4.
(2) Simplified Bishop method and strength reduction finite element method can be checked each other because stability factors obtained by the two methods.
The former is easy to grasp for the first-line technical staff as its principle is intuitively clear, the latter can obtain the potential sliding surface, the stress, strain and displacement data of slope automatically but the calculation process is complex

The measured vibration data needs to be processed by means of suitable and smart algorithms to obtain the requested monitoring output.
In this case the measured data do not include enough information to distinguish between all possible causes of that measured effect.
Such a structure is always used for compressing data, e.g. wavelet transformation of images or Fourier transformation of sounds.
These data are filtered by a 100 Hz analog low-pass filter.
Very often the deviations of measurement data r is not expressed directly by the change of the measured time history signals, instead an intermediate step is introduced to extract characteristic features of the system such as modal data, FRFs, etc.

It integrates heat measurement, data collection and processing, and remote control.
The slave sends data to receiving module, and then to unit collector.
The data can be recorded and processed.
When there’s no data received, the voltage of BUS+ remains unchanged.
When data is sent, LM393‘s output changes with BUS+.

However, the obtained data are frequently corrupted by a wide variety of interferences and such noisy data require considerable efforts to reveal the real information embedded.

After generating the noise-free data sets, a white Gaussian noise was added to each of the data sets to simulate the noisy data before performing de-noising.

It is of note that EBSD data for VT22 alloy gives an exaggerated estimate of percentage of the alpha phase in the structure if compare to evaluation based on SEM data.
In VT6 the most extensive lamellar rotation occurred during the initial stages of deformation (0 to 50% reduction, Fig. 3a).
a b c Fig. 4 EBSD inverse-pole figure maps of the alpha phase for VT6 compressed at 600°C to a 25, 50 and 70 pct. height reduction.
After a height reduction of 50 pct., the number of high-angle boundaries in VT6 increased noticeably (Fig. 4b).
After a 70-pct. reduction, the microstructure of the alloys is partially refined to a grain size of approximately 0.5 µm.

Furthermore, all curves were smoothed by a sliding average filter over n = 10 data points for the analysis of the switching energies and n = 75 data points for the automated evaluation of the diD/dt and the dvDS/dt.
The main part of the reduction appears at turn-on (cf.
The reduction in switching losses by the Kelvin source connection is most pronounced at high currents.
Primarily, the loss reduction is due to the faster turn-on.
Despite the loss reduction at turn-on, proper packages with lower stray inductances, i.e. not only revised standard packages with Kelvin source connection, need to be developed to enhance the efficiency of circuitries with SiC-MOSFETs.

CO2 photocatalytic reduction offers promising sustainable solution.
Additionally, when combined with a PAN matrix, it could potentially serve as a material for CO2 reduction membranes.
(b) The results of calculating the length distribution data with Image-J software.
Based on the data presented in Figure 5 and the percentage analysis of the decline in photoluminescence (PL) intensity, the incorporation of CsPbBr3 into PAN to create a CsPbBr3/PAN fiber composite enhanced the resistance of CsPbBr3 to polar solvents, with water being the medium used in this study.

All these processes performed by the driver have the effect of producing sounds that influence noise pollution; • Land survey of existing buildings, representing their footprints and entering data regarding the number of floors, in other words the height regime of buildings, data on the number of residents, as seen in Fig. 1. [4].
Assessing the six samples, we found that the highest number of people affected by noise is near the primary school, so we presented additional traffic data.
Conclusion In conclusion, we found that supplementing the data stored in the Geographic Information System with data from periodic acoustic measurements at strategic points determined by specialists, would result in higher accuracy noise maps.
Using data from actual measurements, the plans for road traffic noise reduction measures would be realistic.

According to XRD data (Figure 1a), the phase composition of the powder is represented only by perovskite LaFeO3 (ASTM: 37-1493).
The results obtained are in good agreement with similar data for other perovskites [12-14].
According to temperature programmed reduction (TPR) studies (Figure 2b, curve 2), the process of YFeO3 reduction with carbon proceeds from 850 °С, which significantly exceeds the temperature of carbon oxidation process completion.
In the case of LaFeO3 (Figure 2b, curve 1), the reduction process begins at 1100 °С.
The obtained data indicates that, for the perovskites under consideration, the catalytic oxidation of carbon is not associated with the reduction of the catalyst.
