The paper discusses a method of constructing a model of the terrain reflections to land clutter simulation. The basis of this method is the transformation of an array of the initial data calculated using a terrain map into an array with fewer number of elements. The conversion requirements depend on the radar parameters, namely, on the type of outgoing pulse and its processing methods.

Ultrasonic treatment of suspensions containing nanoparticles agglomerates can result in both fragmentation and consolidation of the agglomerates. It has been established with experiment that during prolonged ultrasonic impact (intensity of 4-8W/cm2) on oil suspensions of carbon of detonation synthesis there are variations in particle size (consolidation, fragmentation, again significant enlargement). The paper proposes possible mechanisms and provides a mathematical model to describe these processes.

The concepts of a MicroGrid (MG) and distributed generation (DG) are two subjects that have been presented in the areas of electrical distribution systems. The MG is a cluster of various types of DGs working together to transfer a confident, economical, and environmental power. The MG can operate in two independent conditions: connected or islanding modes. Voltage and frequency control of MG is one of the most significant aspects of its stability. Most DG technologies that can be installed in the MG are not suitable for direct connection to the MG due to their power generation characteristics. Therefore, the installation of these units in the MG, using electronic power interfaces is necessary. Hence, the main concern in MG operation is to control power electronic converters. In this paper, droop control based on Master/Slave method was used in the coordinated control structure for voltage and frequency stability. In this method, when the upstream network was disconnected, MG could operate stably in islanding mode then, the voltage and frequency references were provided to other DGs by Master unit. In order to analyze the method proposed, a hybrid microgrid was considered and simulated in DigSILENT Power Factory. The results have shown that the method proposed ensures the performance of MG at emergency conditions such as islanding MG and MG’s voltage and frequency remained at acceptable level.

Proceeding from the increasing importance of radioelectronic devices, and with an intuitive result, an increased interest in studying and ensuring the electromagnetic compatibility of these devices and especially the critical radioelectronic equipment and systems, a new approach had been applied with a name of “modal reservation In order to investigate the possible options for different arrangements of circuits with reservation, a lot of research work has to be done on those arrangements taking into account so many criteria and factors including the radiation pattern among them. For analysing printed circuit interconnects, the quasi-static approach has an obvious advantage, since the circuit analysis does not always allow obtaining the results of sufficient accuracy, and the electrodynamic one requires significant computational costs. Combining these approaches is proposed, using the calculated results of the current and voltage in multiconductor transmission lines structure from the quasi-static approach, in the electrodynamic analysis to calculate the far-zone field components for the radiation pattern from this structure. The novelty of the estimations obtained is determined by the concept of combining the studied approaches in order to get accurate result, and the fact that they have never been performed for circuits with modal reservation in such a complex form. This paper aims at developing a mathematical model and algorithm which allow calculating the field strength from a circuit with modal reservation using currents in circuit conductors obtained by quasi-static analysis. The algorithm implementation showed acceptable coincidence of current distribution and radiation pattern obtained from a simple test structure by the proposed algorithm and electrodynamic analysis.
