This article presents a technology of the acoustic frequency response equalization. It is based on the usage of the modified x-filtered adaptive algorithms in the equalizers. Comparing to the traditional x-filtered algorithms, the modified ones allow to accelerate the equalizer convergence if the computationally simple LMS or the NLMS adaptive algorithms based on the gradient search strategy are used for the equalizer weights computation. Besides, the modification allows to use the computationally complex but simultaneously efficient RLS adaptive algorithms in the x-filtered mode because the algorithms cannot be used in the traditional x-filtered mode. The proposed equalizer architectures and the computational procedures of the traditional and modified adaptive filtering algorithms are presented. simulation demonstrates a better performance of the modified algorithms comparing to the traditional ones in the following terms: the equalized frequency response ripple value, the proximity of the PSD curves of the undistorted speech signal and the signal passed through the equalizer and acoustic medium, the initial duration of the transient response of the error signal and the response steady-state value.

A novel simple autonomous optoelectronic circuit that demonstrate chaotic behavior is presented. In this circuit a light-emitting diode is a simple optoelectronic element. The mathematical model that contain exponential nonlinearity and six terms with two parameters is described by three first-order ordinary differential equations. A great interest is the simulation that using different software environments allows to demonstration different information properties of chaotic oscillations. For modelling of information properties of the chaotic system and demonstrate results was selected one of the modern software LabView (LabView-2015 (32-bit version for Windows). Temporal dependence of the system is discussed, the chaotic attractors are found and the signal spectrum is given.

The pervasive virtualization of communication networks, including wireless networks, as well as the increasing proliferation of softwarized solutions in wireless communications pave the way for the highly flexible approach for spectrum sharing and pricing. In this paper, the popular idea of freemium licensing is applied to dynamic spectrum sharing and pricing. The proposed softwarized solution is evaluated by means of computersimulations, showing the benefits of such elastic solutions.

This study proposes a method that can easily grasp the relationship between the actual machine and the graphs. In recent years, there has been a lot of research on augmented reality displays. The fields of research range from education to welfare. In the development of control systems, when evaluating the performance of a system by simulation or experiment, the results are often checked as graphs. Since the graphs are checked on a PC using CAD or other means, it is difficult to know which part of the actual machine each graph corresponds to. Therefore, we developed a tool that displays graphs in augmented reality around the actual machine through a camera on a mobile terminal. To display graphs in augmented reality, it is important to obtain the coordinates of the actual machine and display them in a location associated with the device. Therefore, a USD model with the same shape and size as the actual machine is used. This is achieved by displaying the USD model in augmented reality so that it is superimposed on the actual machine. The accuracy of the tool was also examined and its usefulness was evaluated.

The trend towards device miniaturization necessitates a comprehensive understanding of electron emission and gas breakdown at microscales. While traditionally predicted by Paschen’s law (PL), DC breakdown voltage at microscale requires the inclusion of field emission effects with the Townsend criterion due to the enhanced surface electric field due to the decreased potential barrier at the cathode at these length scales. Modifying PL to account for field emission has been the focus of many theoretical, computational, and experimental studies [1] . Previously, we used XPDP1, a 1D/3v (one-dimensional in space, three-dimensional in velocity) particle-in-cell code, to benchmark our DC microscale gas breakdown theory [2] . This presentation explores microscale gas breakdown simulations using SOMAFOAM [3] , a novel finite volume framework for performing continuum simulations for low-temperature plasmas. The results of the two simulation methods will be compared for various pressures and gap distances and the computational efficiency and fidelity of the two methods will be discussed, along with future extensions to larger microscale gaps where gas breakdown transitions to PL and radiofrequency (RF) breakdown at microscale [4] .

The article examines a mathematical model of the selecting phases process of traffic light facilities of the road network section. A Markov decision process with a finite number of actions and states is used as a mathematical model, and the minimization problem is reduced to the Multiagent Reinforcement Learning for Integrated Network (MARLIN) problem. A Q-learning algorithm was implemented and a series of computational experiments were conducted in the Anylogic simulation system for a real section of the Krasnoyarsk road network to study the model.
