Equivalent systems method was implemented for designing the resonator slow-wave structures in plasma-beam devices, and non-impact plasma was used for the filling of the transit channel. The collation of the calculation results demonstrates the adequacy of the developed model in comparison with the real devices and structures. The analysis of the slow-wave structure dispersion characteristics was carried out. The structure of the plasma-beam travelling-wave tube high frequency unit was designed, and using the VEGA software, the tube parameters were estimated.

In this paper, the dispersion characteristics of slow-wave structures suitable for use in devices in the terahertz range are calculated. Slow-wave structures of “winding waveguide” and “counter pins” types can be considered as suitable systems. Analysis of dispersion characteristics of slow-wave structure was carried out by a waveguide-resonator model, which is built for the slow-wave structure of “winding waveguide”-type taking into account a channel for the electron beam. Waveguide-resonator model is consisted of quadripoles which describe the waveguide segments. This model is most accurately reflects the structure of the field in the winding waveguide. Dispersion characteristics were calculated according to the program stated in this paper. These characteristics are used to construct model of millimeter traveling-wave tube, which is in this case the chain of quadripoles. The most common in the solution of these problems is the discrete approach [1]. The difference form of electrodynamic theory of excitation is used to justify the use of a mathematical model of the discrete interaction description [2].

When measuring small, slowly changing physical parameters, such as parameters of the velocity of low-density gas flows, small values of aerodynamic forces, aerodynamic forces acting on aircraft in conditions of a rarefied gas environment, electrical signals coming from primary converters often have a low level, sometimes reaching very small values, is much less than the level of noise and interference. The most acceptable way of measuring such physical quantities in obtaining reliable results is the electromechanical modulation (interruption) of the oncoming gas flow by means of flow interrupters, which allows obtaining the required higher amplification of the signal of the modulated signal, it is easy to separate the modulated signal from the unmodulated noise and interference signal, even if the level of the useful signal is lower than the level of noise and interference. Successful in solving such a problem is the use of signal accumulation, which increases the signal-to-noise ratio at the converter output. The paper presents the results of an investigation of a high-speed pressure transducer for a gas medium of low density. The stability of the metrological characteristics of the converter is investigated using the method of probabilistic study of the stability of the output characteristic of a membrane-capacitive converter to determine the optimum frequency of electromechanical transformation and to ensure the specified accuracy and stability of its metrological characteristics, taking into account the random nature of the deviation of structural and electrophysical parameters associated with destabilizing factors and technological factors.

In this study we use the crossing tree of a signal for the purpose of analysis of H-sssi processes. The crossing tree performs an ad-hoc decomposition of a signal adapted to its dynamics, and represents a natural tool for the analysis of its local fluctuations. We present here a new multifractal formalism and a novel approach for estimating the spectrum of singularities of H-sssi processes using the crossing-tree. The performance of the crossing-tree based method is demonstrated in a numerical study. Its performance is also compared with state-of-the-art techniques based on wavelets, including wavelet-leaders.

In this work, we analyze how the esports transfer market is organized with the help of mixed methods. We assume that a combination of Social Network Analysis and Machine Learning can help to achieve deeper understanding and to find patterns which are hidden from the one-side analysis. For the research, we gathered information about transfers of Dota 2 teams made between The Internationals of 2016 and 2017 and built a network based on this data. For the ERGM, we checked the importance of belonging to one region and organization, difference of skills, and participation in TI, and for association rules, on a par with the regions, we added players roles, and a metric of their personal performance -- fantasy points. Summing up the results, we found out the importance of homophily within regions, detected presence of vertical mobility, and discover the influence of the specific players roles.

Cloud data storages are functioning in the presence of the risks of confidentiality, integrity, and availability related with the loss of information, denial of access for a long time, information leakage, conspiracy and technical failures. In this paper, we provide analysis of reliable, scalable, and confidential distributed data storage based on Multilevel Residue Number System (RNS) and Mignotte secret sharing scheme. We use real cloud providers and estimate characteristics such as the data redundancy, speed of data encoding, and decoding to cope with different user preferences. The analysis shows that the proposed storage scheme increases safety and reliability of traditional approaches and reduces data storage overheads by appropriate selection of RNS parameters.

The paper presents the analysis of the signal integrity in microstrip transmission line with nanoconducting dielectric. It shows the results of calculating the passage of a sequence of pulses of trapezoidal shape to account for losses in copper. It is due to its finite conductivity and skin effect, which significantly affects the high frequency harmonics, and also to the loss in nanoconducting dielectric with a high end-to-end conductivity. It is shown that all these losses are small and the use of nanoconducting dielectrics for eliminating electrostatic discharge is justified.

Recent research on the international Monetary Fund [Global Financial Stability Report, 2015] outlines that participants of fixed income assets market in advanced and emerging market economies have become worried that both the level of market liquidity and its resilience may be declining.

The market liquidity is a many-dimensional concept and cannot be captured by any single measure. Nonetheless, depending on what dimension of market liquidity one is trying to estimate (for instance, time, cost, or quantity) some measures are more informative than others.

Based on the data provided by the National Settlement Depository and the National Fund Association and covered the period from the 6 January 2014 to 15 June 2015 the liquidity of 1497 different bond emissions was analyzed. We calculate a daily liquidity index for each bond using Pareto regularization approach [Gambarov, 2010]. This index is constructed from three bond emission characteristics: trading volume, number of trading days, and number of transactions. We found that the most important factor from these three for Russian bonds is the number of trading days due to the very low trade intensity of Russian fixed income market (the largest part of the Russian corporate bonds even has no active market).

Considering the average liquidity on the Russian bond market we conclude that during last year the deterioration tendency has been dominating on the market. Thus, the main purpose of current research is to analyze which factors bring the major impact on the market liquidity (in particular, weaken) in Russia and in other advanced and emerging market countries.

A lot of factors affect the liquidity of the markets, which can be broadly divided into three groups: risk-driven factors, cost-driven factors and investors and issuers characteristics. It is also worth mentioning that macroeconomic factors (e.g. restrictions on derivatives trading (such as those imposed by the European Union in 2012) have weakened the liquidity of the underlying assets) strongly affect markets in general and liquidity in particular.
