The reconstruction of the magnetic resonance images for different levels of the gradient systems instability is considered. The original technique for minimizing the negative effect of deviations of measurement points in K-space on the quality characteristics of reconstructed tomograms is proposed. On the example of real MR image processing limit values of instability parameters are determined taking into account the possibilities of their compensation. It is shown that the construction of several tomograms for different angular positions of transverse magnetic gradient systems with subsequent integration makes it possible to increase their informatively.

This paper presents a small-signal model of the single-phase asymmetrical cascaded h-bridge multilevel inverter (ACHMI), mainly related to several applications like voltage/current controllers design, power factor control and active power filter, related or not to photovoltaic (PV) systems. The multilevel inverter considered in this work has the asymmetrical configuration, and its individual dc-link voltages are scaled by the factor (1:2:6:…), which guarantee a low Total Harmonic Distortion (THD) in the output voltage. The proposed small-signal model is presented step-by-step considering a case of study related to 3 h-bridge series connected in order to compose the asymmetrical cascaded multilevel inverter topology. An average model (‘large-signal model’) is also presented and both models are discussed in terms of linearization and disturbance rejection around an operational point. A computational model has been developed and tested in MATLAB/SIMULINK environment. Simulation results are presented and discussed in terms of model validation. Tracking performance from the small-signal model was pursued and some conclusions are also presented. Briefly, the model performance validated the approach method of modeling and its capability to emulate the dynamical behavior of the asymmetrical cascaded topology.

Swarm autonomy, coordination and surveillance capabilities for multi-mission multi-functional aerial systems depend on distributed control, sensing and data acquisition. Recently emerged multi-degree-of-freedom microelectronic and MEMS acoustic, electromagnetic, image and inertial sensors empower autonomy, perception of reality, computer vision, augmented reality, situational awareness and other mission-critical tasks. Open problems in system design, complexity and software-hardware co-design motivate authors to focus on fundamental studies and technology developments in sensing and information fusion. Networking and data fusion from multi-mode navigation and image sensors are studied. We examine control and autonomy capabilities emulating tasks and mission environments. The distributed algorithms empower individual-and swarm aerial systems. We report solutions developed in Python, C and MATLAB supporting data processing, data visualization, interactions, interfacing and physical-and-virtual reality. The descriptive reality and information management are demonstrated by performing low-fidelity studies for DJI Phantom with heterogeneous sensors. Augmentation of control and tactical autonomy are studied.

The control optimization technique by the rapidity criterion, based on the maximum principle proposed by L.S. Pontryagin, was applied to the differential equations system, which is describes the DC-motor in time domain, and is constructed based on its dynamic model. A quasi-resonant pulsed converter keeps the DC-motor armature voltage stable. An optimal duration of each pulse in control sequence was calculated. Proposed approach allows calculating both the precision motions and rotations of DC-motor, and at the same time, with the highest possible rapidity. Analytical research was confirmed by simulation and experimental results that are agree each other accurate to a few percent. Proposed method allows calculation the optimal motion trajectories for precise magnetic recorders and robotic arms.

Analysis of the conductive electromagnetic interferences (EMI) of the Half-bridge GaN development board EPC9062 is described. An equivalent circuit of the power stage and its mathematical model as a source of EMI is proposed. The modeling is performed in the range from 150 kHz to 30 MHz. The influence of the Common Mode component on the overall EMI level with an increasing of the switching frequency is analyzed. The graphs of the calculated and experimental EMI at the line impedance stabilization network (LISN) output are built. Experimental results and calculated ones are well matched.

A simple two-component model of seasonal and diurnal variations of atmospheric transparency is proposed.

Electron spectrum in doped $n$-Si quantum wires is calculated by the Thomas – Fermi (TF) method under finite temperatures. The many-body exchange corrections are taken into account. The doping profile is arbitrary. At the first stage the electron potential energy is calculated from a simple two-dimensional equation. The effective iteration scheme is proposed there. Then the energy sub-levels and wave functions are simulated from the Schrödinger equation. The expansion by the eigenfunctions of the linear harmonic oscillator is used. The quantum mechanical perturbation theory yields goods results for the lower energy sub-levels.

Today rapid growth of distributed generation can cause some problems that related with power system stability. The mathematical models and algorithms are playing a major part in evolution of electronic systems. Therefore, the improving of models and algorithms is fundamental problem in further systems development. The algorithm for information support an automated system has been studied. The inertia constant, which representing dynamic property of electric generator, has been founded by analyzing components of mathematical model, describing dynamics of power system. It should not be forgotten, however, that the most of the distributed generation control systems have focus on power control (P and Q) to achieve reliable operation of the local grid. The suggestions about supplementing control system algorithm of power system with distributed generation sources for concern of their dynamic properties are made. The supplementing consists of including information-feedback system (IFS) module on all hierarchical levels. This module includes data and algorithm of analyzing the stability. The structure of module and database are developed.
