Usage of agent-observer in simulation optimization, especially in optimizing system behavior is discussed in the paper. The agent allows you to observe, for the dynamics of changes in the parameters and behavior of the model. Changing some parameters leads to a significant reduction in simulation time.

The optimal filtering problem for non-stationary stochastic continuous-time observation models is considered. It is known that the problem solution can be found using both the Duncan-Mortensen-Zakai equation and the robust Duncan-Mortensen-Zakai equation. In this paper the special form of the robust Duncan-Mortensen-Zakai equation, where the drift, diffusion, and potential functions are expressed in the way allowing to apply the particle method, is derived.

Security is the challenge that world community will need to overcome for the Internet of Things (IoT) comes true. It needs to protect IoT users from known and potential attacks. The traditional approach for security system design is expected to fail, because most threats in IoT environment will be previously unseen and many IoT devices have constrained computing resources. The recent surveys of intrusion detection systems in wireless sensor networks and IoT applications do not mention some novel attacks such as depletion of battery, denial of information etc. There is a lack of methods for comprehensive analysis of novel attacks. Thus, in the presented paper we consider a model of wireless network node behavior under energy exhaustion attacks.

This paper considers the method of pattern recognition based on a convolutional neural network using Sobel filters. Parameters of the convolutional neural network blocks were chosen experimentally by software modeling in MATLAB. We presents the architecture of the convolutional neural network constructed with residue number system for delay minimization. Using of special type of modules allows to accelerate the work of the device by 37,4% as compared to using a binary number system and by 18,5% as compared to using a known residue number system realization.

The paper describes the simple technique for the quarter-wave symmetric output voltage waveform formation of the three-phase multilevel inverter. This technique is based on the applying the appropriate natural nonsymmetric three-segment vectors switching sequence to the recently proposed simple voltage source multilevel inverter space vector PWM algorithm. Some Mathcad simulated voltages waveforms and loci are shown, and the delta voltage total harmonic distortion (THD) and first three orders n-order integral voltage harmonics factors are presented as the functions of the amplitude modulation index.

This paper shows the analysis of median filters with weighted central elements using for cleaning of images from impulse noise. The influence of the probability of obtaining undistorted pixels and distortion of the image pixel distribution function on the processing result is shown. We demonstrated that median filters with a 3×3 window allow to obtain a higher quality of image cleaning from noise with a low probability of impulse noise, and median filters with window sizes of 5×5 and 7×7 allow to obtain a higher quality of image cleaning from noise with high probability of impulse noise. The obtained result may be used in medical imaging and adaptive filtering systems for photo and video data processing.

This paper is focused on the analysis of linear and nonlinear mode coupling in space division multiplexed (SDM) optical communications over step-index fiber in few-mode regime. Linear mode coupling is caused by the fiber imperfections, while the nonlinear coupling is caused by the Kerr-nonlinearities. Therefore, we use the system of generalized coupled nonlinear Schrödinger equations (GCNLSE) to describe the signal propagation. We analytically show that the presence of linear mode coupling may cause increasing of the nonlinear signal distortions. For the detailed study we solve GCNLSE numerically for the standard step index fiber at the wavelength of 850 nm in the basis of spatial modes with helical phase front (vortex modes) and for a special kind of few-mode fiber with enlarged core, providing propagation of five spatial modes at 1550 nm. Simulation results confirm that the linear mode coupling may lead to a significant increase of the nonlinear distortions. It is necessary to take this phenomenon into account in SDM systems with linear compensation of mode coupling, because the nonlinear distortions may sufficiently decrease the effectiveness of the compensation.

Hybridization of models for various methodological contexts are considered. This enables to improve the objectivization of competency assessment. The results obtained can be applied to building both educational competencies and those required by employers. The peculiarity of the methodology is supposed to be a risk-tolerant method used for improving the objectivity of competency assessment in the unit: teacher-student (expert-testee).
