Little data exists in the literature, however, to link the effect of incomplete recrystallization on the mechanical response of ferritic stainless steels.
Despite the level of simplification used in developing Eq. 4, it describes the experimental data very well.
Filled symbols represent experimental data while hollow symbols represent the results of relaxed constraints Taylor calculations assuming {110}<111> and {112}<111> slip systems.
The agreement with the experimental data is good considering the level of simplicity associated with the argument made here.
Data taken for samples tested parallel to the rolling direction.

The device sequentially processes data of DTA and IDS samples, controlling the temperature of the substance coherent combination at the time of formation in the boundaries of structural and cluster units.
The thickness reduction to the nanoscale level recorded by the device.
Data preparation of discrete isothermal heating unlike thermoanalytical continuous heating is experimental support in the form of graphical charts.
Thermal and temperature effects are complementary, representing discrete data in continuous grid temperatures, making the value of each reference.
The database should be filled, receiving the scanning data on substances not previously studied in this way.

The limited number of records for the soils class D and E classes in the data-base leads to non-consideration of this soils for here.
Table 1 Record data returned by REXEL for soil A.
The preliminary step to use the ANN is the training or the calculate of the synaptic weights and bias in an iterative way pending produces data compatible outputs.
The entire set of data (i.e., data used for learning, validation and testing) has been passed through the network to perform a regression between the output network values Y and the corresponding target A.

Format Specifications An STL file consists of a list of facet data.
CALYPSO software (Fig. 6) was used for data evaluation in both cases.
It depends on the performance of the machine used for getting data.

As can be seen from Fig. 5, the calculation process inside template is driven by both control flow and data flow.
Control flow represents the predetermined calculation process according to algorithm and empirical formulas while data flow represents data input and output in every module.
Interface data are usually classified into three kinds: initialize data, adjustable data and results data.
Data type can be marked clearly according to data flow diagram.
The calculation process inside the model template is driven by separated control flow and data flow.

Color reduction technique, intensity based method for edge detection and horizontal based localization approach are applied here to fulfill the algorithm.
Another approach to verify integrity of digital images is inspired from the use of cryptographic hash functions for data authentication.
If the image data is not represented in YUV color space, it is converted to this color space by means of appropriate transformations.
Our method only uses the intensity data (V channel of YUV) during further processing.
The whole test data consists of 50 images.

This research uses spatial data to create flood risk modelling for the Katingan Regency.
Administration Map of Katingan Regency Data Vector and raster data collected from credible sources are used in this research.
The table below shows details of the data used in this research.
It is a cloud-based platform, and everyone has free access to this platform, which makes it popular since Google Earth Engine not only provides free access to a wide range of raster data but is also capable of meticulously completing a wide range of raster data processing, from data acquisition to data post-processing.
ArcGIS software was used to create a map by overlaying all vector data.

The method consists in pouring a melt into the rotating rolls, crystallizing it on the roll surfaces, rolling with a predetermined reduction amount, pressing out in front of the die and squeezing out the product of the predetermined configuration and dimensions through it with drawing ratio in the range of values 10-40.
Device for twin roll casting-extruding solid (a) and hollow (b) extruded products under the patent [14]: 1 – holding furnace; 2 – melt; 3 – roll with a stream; 4 – roll with the protrusion; 5 – water-cooled cavities; 6 – matrix; 7 – needle; 8 – collar; 9 – clamp; 10 – screw; 11 – holder; 12 – channels for lubricant supply; 13, 14 – springs; 15 – crystallized metal; 16 – extruded product The device (Fig. 3) in accordance with the patent [15] allows expanding technological possibilities due to an increase in yield, reduction of metallurgical processing cycles, reduction of labor and energy intensity of the process, and also improvement of the quality of extruded products due to improvement of mechanical properties.
The data obtained correspond to the level of mechanical properties for the alloy and its analogues, cited in the reference literature [17, 18] and standard EN 754-2.

. (+48 22) 261851447 e-mail: leszek.ulanowicz@itwl.pl Keywords: technical condition, hydraulic system, Flight Data Recorders, the pressure Abstract: During the ongoing operation of the hydraulic system you need a drive control information capable of maintaining fitness.
Aircrafts are provided with Flight Data Recorders (FDR) that are meant to keep records of flight parameters, data acquired from on-board instruments as well as systems and activities of the aircraft crew.
The indispensable provision for that is keeping records on pressure variation across the avionic hydraulic drive by the Flight Data Recorder (FDR).
Fig. 4 presents an example of a graph for pressure variations in the avionic hydraulic drive downloaded from the Flight Data Recorder of a military jet airplane.
Example of waveforms for variation of pressure in an avionic hydraulic drive stored in the Flight Data Recorder (FDR). 1) movements of the rudder (flight in a tight bend); 2) movements of the elevator (barrel roll) 3) repositioning of wings to the position of 60º; 4) repositioning of wings to the position of 30º; 5) activation of decelerons; 6) activation of flaps; 7) lowering of undercarriage; 8) retraction of undercarriage and flaps; 9) lowering of undercarriage and activation of flaps; 10) engine shutdown (the hydraulic pump drive) on the ground.

Reduction, reactive and chemical processes are commonly used methods in the TiB2 production.
Carbothermic reduction of TiO2 and B2O3 powder mixture, reduction of the TiO2 with B4C and metallothermic reduction of TiO2 and B2O3 are some of the reduction processes, which are summarized below.
Carbothermic reduction reaction: TiO2 + B2O3 + 5C → TiB2 + 5CO (1) Boron carbide reduction reaction: 7TiO2 + 5B4C → 7TiB2 + 3B2O3 + 5CO (2) Aluminothermic, silicothermic, magnesiothermic reduction reaction: TiO2 + B2O3 + Al (Si, Mg) → TiB2 + Al2O3 (SiO2, MgO) (3) Borothermic reduction reaction: TiO2 + 4B → TiB2 + B2O2 (4) Reactive process is the simplest method, which involves the direct reaction of elemental precursor Ti or TiH2 and B powders for the production of the high quality TiB2 powders.
Linear fit of the data points represents that the hardness has an exponential dependence on temperature and it follows the following theoretical model.
An important requirement of cathode material for aluminum reduction cells is that the material should be wetted by aluminum.
