An analytical review of tissue-engineered implants for the cardiovascular system tissues regeneration was carried out. A comparison of laser methods for manufacturing cellular scaffolds was made. On the basis of theoretical studies, the possibility of creating a nanocarbon scaffold under the action of laser radiation has been proved. This scaffold is used to reinforce scaffolds based on protein matrix.

To improve the sensitivity of the MEMS comb — drive inclinometer three shapes of the comb-drive: ordinary, triangular and curve were investigated. We used typical folded beam for displacement of rotor part. By calculating the results in ANSYS, the change of capacitance in curve shape comb-drive is more than in the other shapes. And the quality factor of curve shape actuator is higher than in other shape actuator. The curve shape comb-drive is more suitable for getting higher sensitivity for comb-drive MEMS inclinometer.

In the paper, the problem of excitation of cylindrical anisotropic impedance metasurface (MS) with input piecewise homogeneous bigyrotropic covering is formulated and solved. Influence of the covering is introduced with the two-sided impedance boundary conditions Asymptotic representation of total radiation far fields of the sources is found with eigen function method. Cylindrical phased antenna array model made of ribbons of exiting current on impedance MS with input covering is considered. Radiation patterns of the antenna array are obtained for linear co-polarizations and cross-polarizations. It is shown, that radiation patterns and polarization characteristics of the antenna array are determined in explicit form by tensor of impedance of cylindrical MS. Metasurface can be used to form and control radiation polarization of phased antenna array.

The study of the influence of field emitter design parameters on electric field and current-voltage characteristics using Sentaurus TCAD simulation was carried out. Electric field distribution and current-voltage characteristics were calculated for single vertically placed carbon nanotubes (CNT) and CNT-bundle. Silicon columnar structures with horizontally placed CNT were also analysed. For vertically placed CNTs it was shown that increase in aspect ratio by reducing the CNT diameter leads to significant increase in emission current. For columnar structures it was shown that maximum electric field near the horizontally placed CNTs much less than the field near the vertically placed CNTs with similar anode-cathode voltages. Emission current is negligible at CNT work function φ>2eV.

The paper refers to the development of computer model, which allows to iteratively calculate the maximum power capacity of the three-phase overhead or cable power line. The model considers two factors, which coexistence is known for complicating estimations of the power, consumed by the load, namely: impedance of the grid voltage source and static load characteristics (VI or VAR curves). The modelling of the load as current source, which current is a function of the voltage magnitude at the power line output, allowed to consider static (V-I) characteristics of the load. The model was implemented in the Simulink environment, which iterative nature of calculations allows to converge the grid output and load input voltages and currents after the transient, and therefore to consider parameters of the steady-state operation as sought-for solution.

The article represents the analysis of the causes of damage on the on-load tap-changer of a dry-type transformer installed at a 35 kV substation under ground fault in a network with isolated neutral. In order to analyze these processes, the well-known technique of modeling transients in a transformer [1, 2] is supplemented with account of the interturn and interwinding capacitances of the transformer determined from the picture of the electrostatic field.

This paper discusses the methods of analysis of the active power oscillations occurred in a motor drive propulsion shafting system under variation of the rotational speed and load condition. The oscillation in the supplied active power generates the system vibration and increases the drive motor loading. It has been shown that the installation of the vibration dampers significantly improves the system performance and decreases the influence of the active power oscillation particular at resonance frequencies. The paper considers two model of the system — equipped with magnetorheological dampers and without. The simulation results shown that efficient vibration damping can be achieved using the appropriate control of the magnetorheological damper properties.
