Authors demonstrated in previous publications that data mining methods could reduce data demand even to 1% in comparison do SA in the task of investigating of importance of the predictors.
In this article we present how data mining algorithms can discover relationships in large datasets.
Decision tree divides a training set into partitions to the point where each partition contains data belonging to one class, or, if within the partition is dominated by data belonging to one class.
All cases of data are divided among v groups Z1, Z2, ..., Zv of the same cardinality, as far as possible.
To have certainty of results we used 10% of data - sample was drawn randomly.

A further increase in the amount of CaCO3 particles leads to a significant reduction in the barrier, which at the gypsum-to-filler ratio of 70:30 is 6 kT, and at the ratio of 50:50 completely disappears.
Calculating the Interaction Energy The data obtained as a result of studying electrokinetic phenomena in the gypsum solution and in the solution-base contact zone showed that the most effective reduction of the electrokinetic potential is characterized by a gypsum mix filled with 50-70% finely ground mineral calcium carbonate [3].
A further increase in the amount of CaCO3 particles leads to a significant reduction in the barrier, which at the gypsum-to-filler ratio of 70:30 is 6 kT, and at the ratio of 50:50 completely disappears.
It follows from the given data that the stability of aqueous dispersions of gypsum and CaCO3 with particle diameters of less than 60 μm depends significantly on the ratio of components, and their behavior can be explained on the basis of the DLVO theory with the involvement of the concepts of heterocoagulation.

In the industrial point of view, the reduction of development time process to reach a sheet resistance target is needed in terms of development cost reduction.
Table 1 : Average measurements datas of sheet resistance and carrier lifetime for BCl3 diffusion process.
De Frésart et al studied B203 decomposition by Si and reported that energy activation of this reduction was EA=4.5±1eV including B2O3 decomposition and SiO2 formation [5] [6].
The similar temperature dependence between B2O3 reduction and kBoron parameter suggest that our equivalent model is a good approximation of diffusion process.
The kBoron parameter was introduced to fit experimental data as function of the diffusion temperature.

The node only can transmit its data when the channel is idle.
The second technique allows a slave, when polled, to send directly acyclic data to the master.
When acyclic data are generated, it allows a slave to immediately try to send data to the master.
This method breaks the transmission data into three categories, namely non-periodic real-time data, periodic real-time data and non-real-time data.
They have different priorities, competing for the channel by different way: non-periodic real-time data that has the highest priority enters the maximal priorities queue waiting for dispatch, using RTS/CTS infor- mation exchange mechanism; while periodic real-time data and non-real-time data use CSMA/CA.

Project carbon emission reduction must be achieved by low-carbon construction, low-carbon production and low-carbon operation, in which some projects gain carbon trading benefit at the same time.

A PC based oscilloscope data system, with maximum resolution of 16 bits and frequency of 20 MHz per channel was used to acquire the signals.
Conversely, if there is a reduction to each sample taken, the CV average should be considered.
Relationship between the samples sorted and population reduction.

It is necessary to note that the designated positive effect was reached at reduction of the content of polymer in a polymeric component.
It leads to reduction of its tensile properties and reduction of an interval of plasticity of PBB.
Comparison of data on elasticity shows that at the maintenance of DST of 2-3 % on weight in the polymeric matrix nanoreinforced of 0,002 % for OUNT, elasticity of PBB reaches the greatest value - more than 90 % at 25°C and more than 80 % at 0°C.
Further reduction of OUNT in the binder doesn't give significant technical result, because of absence of effect from nanoupdating of a polymeric component.
Thus, at the expense of a variation reduction of the content of DST polymer in binder, and also receiving a target product with high indicators of properties becomes the maintenance of components in the nanoreinforced matrix of a polymeric component, possible.
