Piezoceramics phases of (1-х)PbTiO3-xPbZrO3 is the basis of most high-performance piezoelectric materials. Electrophysical and mechanical properties of these materials can be varied over a wide range by varying the composition and by processing methods: the methods and modes of sintering conditions polarization. Topical to study the influence on the properties of PZT materials processing methods at the stages of manufacturing piezoelectric samples. In the role model of the object has been selected multicomponent system PbTiO3-PbZrO3-PbNb2/3Zn1/3O3-PbW1/2Mg1/2O3-PbSb2/3Mn1/3O3. Samples of piezoelectric elements for the study were obtained in two ways: in the first case, the sintering samples was carried out by the usual ceramic technology, and in the second by hot pressing. The grain structure was formed in both cases in the presence of the glass phase, the quantity of which decreases with increasing temperature, while in the first case, an increase in the velocity of the secondary recrystallization, and in the second of its suppression. It was found that regardless of the technology of the samples εT33/ε0, d33 and VЕ1 at high temperatures, due to the increase of grain and coercive field, which complicates the process of polarization. Maximum values εT33/ε0, d33 and VЕ1 samples prepared by hot pressing at 10 - 15% higher than if received by conventional ceramic technology.

Strength properties of high-strength concrete on the basis of a mixture of high-calcium ash and cement crushed to a specific surface of 600 m2 / kg in the presence of a superplasticizer were investigated. It was established that at the initial stages of hardening of the binder, its strength strongly depends on the dosage of fly ash and it depends little on the water/binder ratio. After 28 days of hardening, the strength of concrete, depends more on the water-binder ratio, rather than on the ash content of the cement-ash binder. There was concluded that minerals of fly ash affect on strength of the cement-ash binder in later periods, and at the initial stages, its hardening is provided by hydration of the cement clinker. It was established that in high-strength concretes was no decrease in strength in later periods when using finely grinding ash containing a significant amount of free CaO.

The object of system analysis is increasingly becoming a geopolitical constructs. The part of the system analysis is to focus on the classification aspects of the structural elements of such a geopolitical entity as the Black Sea-Caspian region. Classification analysis is focused on actors (players), initiating "the Great game" in the political field of the region. We propose consideration of the morphological (elementwise) of the Black Sea-Caspian region, followed by the ranking of "local" actors and building of the "crystal lattice" on a regional scale. For the study of actors we are propose to use additive and integrative approaches. First is to involve sequential consideration of three geographical sub-regions "Black Sea – Caucasus – Caspian" as sites of "place-action". The second approach comes from the impossibility of a clear definition of natural boundaries "of the Black Sea, Caucasus and Caspian basin", taken separately. The authors propose for the boundaries in a purely geographical sense to understand some of the transition area between environments and/or spaces with qualitatively and quantitatively different properties and parameters. Actually there is "overlay" above three sub-regions, their intersection, fact that "stay" of some States of this zone in several of these subregions.

This article considers influence of route vehicle traffic volume on the road network capacity. The atrcile introduces the change of passanger traffic according to hours of the day on the bus routs, which are laid through signaled crossings of streets Kyubisheva - 8 Marta in Yekaterinburg nearby big transfer transport junction in the distric of subway station ""Geologicheskaya"". Recieved data gives an opportunity to identify percentage of buses in the transport stream. It is one of the factors that influences on the calculations of the length of traffic signal cycle. The analysis of received statistical data lets us draw the following conclusion: 1. To reconstract network of streets and provide the maximal traffic capacity on the crossings, it is necessary to consider variable structure of transport flow. 2. To calculate the length of traffic signal cycle it is necessary to consider the bus traffic volume, which changes according to the time. 3.There was determined the change dependency of passanger traffic on hours of the day on the bus routs. It gives the possibility to predict changes in the length of traffic signal cycle. 4. Recieved results can be used to calculate the length of traffic signal cycle and in order to developn an optimized route network of passenger transport.

In accordance with the theory of mathematical and statistical modeling, evaluation studies, selected the main characteristics of the models describing the studied production process of fiberboard using different types of binders. In accordance with the developed plan of the selected controlled studies, uncontrolled and controlled factors of the process under study. The levels, steps, and intervals of variation of the studied factors. As a method of obtaining the mathematical dependencies of the quality indicators of fibreboard from the kind of used binder was enacted active single-factor experiment. The results of the studies conducted statistical analysis of the dependence of physical-mechanical characteristics of the performance of the finished plate thickness fibreboard manufactured by wet and dry methods, interpretation of research results, quantitative and qualitative relationships between the studied parameters.

"One of the major drawbacks of modern alloyed metal cathodes Pd-Ba is the inhomogeneous distribution of the intermetallic Pd5Ba in the matrix Pd. This fact leads to an underestimation of life and technical performance of devices of microwave electronics on the basis of the cathodes. A substantial improvement in uniformity of cathode alloys Pd-Ba should lead the operation of mechanical activation of powder Pd, carried out prior to its compression process. The paper studied the effect of mechanical activation on the particle shape, particle size distribution and dispersion of powder Pd. It is shown that mechanical activation results in a substantial reduction in the average size and average particle size of Pd powder, as well as a substantial increase of the specific surface of the particles. The optimal regimes of mechanical activation of powder of Pd with a view to its use for metallosplavnyh cathodes."

The article presents the results of the analysis of the fluctuations of the USD/RUB and the definitions of integrability of the corresponding time series. The research of currency pair by linear methods revealed the presence of non-stationarity in the behavior of the time series, as a result we came to the conclusion that it is impossible to create a high-quality predictive model based on parametric methods.An attempt was made to improve the quality of the forecast to study the integrability of the time series. For this purpose we used various modifications of test the Dickey–Fuller and software products. We tested estimate the order of integrability of two economic time series ,characterizing fluctuations of the U.S. dollar against the ruble and the dynamics of the stock of the Sberbank. The results of the analysis prove that the Dickey-Fuller test is a simple and reliable way to assess the order of integrability of the time series. The benefits of the ADF-test before DF-test are identified.The result is a stationary model of time series , which we can used for forecasting.
