The article is devoted to the issues of solid oxide fuel cells (SOFC) on biogas integration into the power supply system of a livestock enterprise. The problem of the optimal SOFC’s capacity selecting is being solved. The object of the research is the power supply system of a livestock enterprise. A mathematical model of a power supply system operation with the biogas-powered SOFC has been developed. Using a computer program based on Microsoft Excel and a SOFC’s database, a study of the effectiveness of SOFC’s integration into the power supply system has been carried out. The dependences of energy, economic and environmental efficiency SOFC application indicators (installed capacity utilization factor (ICUF), levelized cost of energy (LCOE), total costs for power supply, discounted total costs for power supply, volume of used biogas) on the SOFC’s capacity have been determined. A methodology for selecting the optimal SOFC’s capacity taking into account the criteria of economic and environmental efficiency has been developed.

This paper discusses the problem of ensuring the safe (accident-free) autonomous vehicle (AV) movement along a trajectory. The task of ensuring the safety of autonomous vehicle movement along the trajectory is formalized. The article describes a model that quantitatively assesses the level of autonomous vehicle movement safety based on the analysis of the environment map using a risk-based approach. A method for finding the optimal moment of time for an emergency stop of an AV is presented on the basis of minimizing possible damage (losses) by analyzing the change in collision risk as a safety indicator. The author has simulated a collision between an AV and an obstacle in Matlab Simulink. The probability densities of the collision risk values in the event of an AV hitting an obstacle and in the absence of an accident were constructed based on the simulation results. The author has shown the possibility of using the results of accident modeling to solve the problem of ensuring safe autonomous vehicle movement.

The paper considers the numerical modeling of heat and mass transfer processes in an oil well complicated by asphalt-resin-paraffin deposits, taking into account the heating of the oil fluid flow by a heating cable. The results of numerical experiments were obtained by implementing a three-dimensional axisymmetric mathematical model based on the laws of conservation of mass, energy and momentum vector, and taking into account the multilayer structure of the well and the phenomenon of heat and mass transfer. The numerical study was carried out in the ANSYS Fluent finite element analysis environment, using the finite volume method. An assessment of the adequacy of the results obtained with the existing engineering methods for determining the temperature in production wells and the depth of the onset of wax crystallization has been carried out. The effectiveness of such a method of combating paraffin deposits as a heating cable at various well flow rates has been investigated. Temperature distributions were obtained along the entire length of the well on the tubing wall at different flow rates.

The paper considers the issue of assessing threats to information security in industrial automation and telecommunication systems in order to improve the efficiency of their security systems. A method for determining a quantitative indicator of threats is proposed, taking into account the probabilistic nature of the process of implementing negative impacts on objects of both industrial and telecommunications systems. The factors that contribute and (or) initiate them are also determined, the dependences of the formal definition of the quantitative indicator of threats are obtained. Methods for a quantitative threat assessment as well as the degree of this threat are presented in the form of a mathematical model in order to substantiate and describe the method for determining a threat to industrial automation systems. Recommendations necessary for obtaining expert assessments of negative impacts on the informatisation objects and information security systems counteracting are formulated to facilitate making decisions on the protection of industrial and telecommunication systems.

An approach to estimate the performance of a load distribution and balancing system for data center server clusters is proposed, which takes into account the current load (occupancy) of servers. This system is described in mathematical terms, focusing on the server states at each instant of receiving service requests in a steady-state mode. The capacity and response time to customer requests are used as the main performance indicators. These indicators are estimated using queuing theory and simulation modeling as mathematical apparatus. The flows of service requests are stationary and ordinary. The receipt and processing of service requests are described by Markov processes. The load distribution and balancing system is represented as a multi-channel queueing system with a limited queue length, which includes an unlimited buffer (disk memory) for all servers in the cluster and input buffers of limited capacity for each server. The effectiveness of the proposed model and the theoretical results are verified by simulation, and experimental data are obtained.

Prosody can be referred to those elements of speech that represent the properties of syllables and larger units of speech. Prosody also includes individual linguistic functions such as rhythm, accent, and intonation. Prosody makes it possible to identify the speaker's vocal personality or the characteristics of utterances, such as the speaker's emotional state or the style of utterance. Studying dialects or languages often requires prosody markup. The article is devoted to automatic prosody markup based on the fundamental frequency of the utterance. With the extraction of the fundamental frequency being the main challenge multiple methods are reviewed such as SOTA neural networks and more conservative algorithms. After applying one of these methods, SLAM markup is obtained. In the end markups based on differently obtained fundamental frequencies are compared.

The article is devoted to the issues of algorithmic support when using force-torque sensing for robotic assembly of shaft-hole type connections. The assembly system consists of an ABB IRB 140 industrial robot equipped with a Schunk GSM-P-64-E-180 pneumatic gripper and a Gamma SI-65-5 six-component force-torque sensor by ATI Industrial Automation. The robot positioning accuracy is insufficient for precision joints assembly. This can cause misalignments (linear, angular) of the parts axis when performing a technological assembly. This can lead to unwanted contact interactions. If the robot movement strategy remains unchanged, the phenomenon of jamming may occur. Therefore, it is proposed to use force-torque sensing to recognize contact interaction at assembly. The sensor is installed in front of the gripper of the assembly manipulator. The difficulty in solving this problem is that the force-torque sensor signals do not contain direct information about the position or orientation of the connected parts. To correct the robot movement it is necessary to recognize the position of the parts contact point by means of force and torque sensor signals. For this purpose, the equations of the forces - torque relationship were derived. The sensor whose parameters determine the position of the parts contact point measures force and torque values. The article considers the case of a one-point contact of the connected parts, which occurs at an unsuccessful matching. Based on a computer simulation of the process, it became possible to establish some common factors between the signs of force effects and the contact point position. The main purpose of this research is to develop an adaptive algorithm that corrects the movement of an assembly robot. The algorithm is based on the information about the forces and torques from the sensor, as well as the data on the operating element position. The use of a position-force control algorithm for robot movement will make it possible to perform a reliable assembly of precision joints. The article describes the limits on the force and torque sensor sensitivity as applied to the recognition of the part angular orientation at assembly, caused by contact interaction.

This paper analyzes why relay protections (RP) disconnect generator sets (GS) at distributed generation (DG) facilities during transients, and what could such disconnection result in. Gas-piston unit (GPU) manufacturers configure the RPs in such a way that a short-term frequency deviation may cause an unnecessary disconnection. The worst scenario is when a microgrid that carries a DG facility becomes islanded with an active power imbalance, or when a microgrid is islanded while having to maintain an industrial load. How specifically a transient goes depends to a great extent on what comprises the load and on the resulting stability of AC motors within the microgrid. Simulations carried out as part of this research show that using static devices (an energy storage unit, ESU, and an active load, AL) is an effective solution that can prevent unnecessary GPU disconnections. The paper thus provides recommendations on how to calculate the electrical parameters to optimize ESU and AL configurations. Use of state-of-the-art static devices coupled with additional engineering helps prevent unnecessary GPU disconnections and ensure continued electricity delivery to industrial loads in case a transient causes a short-term frequency deviation.

The main priority of modern astronautics is improving fuel efficiency and increasing payload mass. Multistage aerospace air-launch systems are one of the best choices for solving this problem. The complexity of such kind complexes presupposes the organization of automatic control modes. The problem of designing a new class of autopilots becomes actual due to requirement toughening to reliability and efficiency of airborne system and expansion of the range of tasks to be solved. Method of analytical design of aggregated regulators (ADAR) was used for synthesis. The aerospace complex includes a carrier aircraft and an upper stage located on top. They are connected by three nodes, nasal and two main. The article considers the applied problem of synthesis control algorithms for the separation of the upper stage and carrier aircraft with the simultaneous breaking of all connections between them. The controller is synthesized using a full nonlinear mathematical model of longitudinal motion of the system, taking into account aerodynamic interference and forces in communication nodes between - upper stage and carrier aircraft. Demonstrated exact implementation of specified control goals.
