Microwave energy can be used for heating, drying, pasteurization and thawing of different foods, as this technology is suitable for processing various dielectric materials, efficient and environmentally friendly. This paper is devoted to simulation of energy absorption in a liquid pasteurizer. The device consists of a rectangular waveguide with hollow dielectric tubes passing through it. Flowing through the tubes, the liquid absorbs microwave energy and heats up. The electric field distribution in the waveguide and specific absorbed power are simulated for various parameters of the device using a specialized computer-aided design software. Based on performed calculations, the angle of inclination of the tubes equal to 43° is optimal. It is not possible to achive an even power distribution across all the tubes, and the power absorption in the first and last tubes differs by about 20 times. However, the liquid flows through all tubes consequentially, therefore, the resulting unevenness is acceptable. The evaluation of precision of the results is performed.

In this paper, an approach to automating the conduct of behavioral audit of transport safety is considered. Also, it is proposed to use cameras and electromyographic sensors directly attached to an employee of the organization - to monitor his condition in real time. In a similar way, it is possible to determine the emotional state of transport operators, their fatigue by analyzing a series of received images of a person and read signals from wearable sensors when directly in the process of performing a work task. The strongest emotions, such as happiness, surprise, as well as determining a person’s fatigue, can be determined by individual segments of a person’s image - the state of his eyes, mouth, eyebrows, head position. It is possible to increase the accuracy of determining the operator’s reactions, for example, by using electromyographic sensors installed on the operator’s face and hands.

This paper presents a statement and solution to the problem of heat losses in a ground heat accumulator. A numerical solution to the problem is presented using the finite difference method on an uneven grid along the horizontal axis and uniform in depth, approximation of the differential heat equation according to the scheme with the second order of accuracy in the coordinate, and direct reduced Gaussian method for solving a system of linear equations. The number of grid steps is selected automatically according to the Runge rule. The results of numerical simulation are obtained and presented. An assessment of the accuracy of the calculation based on the external heat balance was carried out. The value of heat losses and the conditional radius of soil heating, which is subject to excess heating from the heat accumulator, is determined.

During the operation of water treatment plants at thermal power plants with combined cycle gas turbines, colonies of microorganisms are formed, which negatively affect the operation of the equipment. The types and number of bacteria depends on the source of water supply, seasonality, and water-chemical regime. The aim of the research is to analyze and quantify the bacterial contamination of a mixed-bed filter in a laboratory setup. To determine the number of bacteria and the contamination of ion-exchange resins on the mixed-bed filter unit, the following methods were used: ATP luminometry with a System SURE Plus device, evaporation and separation of a mixture of substances under reduced pressure on an IKA RV rotary evaporator and infrared spectroscopy of substances (FTIR, Shimadzu). As a result of the research, data on the number of bacteria in water samples were obtained on a laboratory installation of a mixed-bed filter, a spectral analysis of the bacteria present in the regenerative solution was carried out. The number of bacteria was determined at each stage of research. On a laboratory installation of a mixed-bed filter, the process of development of microorganisms that reduce the performance of ion-exchange resins has been revealed.

The study of the physics of a nuclear chain reaction as a sequence of fission cycles has established a positive effect of asymptotic limiting of nuclear reactor power after the insertion of positive reactivity and raised the question whether a similar power asymptotic after the insertion of negative reactivity would occur, which could lead to the failure of the emergency protection function of the reactor to establish its subcritical state. The purpose of this paper is to study the power behavior of a point nuclear reactor during staged insertion of large negative reactivity and the performance of the emergency protection of the reactor's nuclear safety requirements for stopping the fission chain reaction. The study is conducted by solving the kinetics equation composed in the representation of the nuclear chain reaction as a sequence of fission cycles. It is established that activation of reactor emergency protection does not stop the chain reaction due to the formation of a secondary chain reaction on delayed decay neutrons of accumulated precursors. It is shown that the reactor can be brought to a subcritical state if a slow core insertion system, such as fuel burnup compensation, is started in parallel with the emergency protection system.

The algorithms for determining the direction of arrival (DOA) to jamming signals for a planar elliptical digital antenna array (DAA) are presented. MVDR and Root-MUSIC are the considered, which make it possible to determine the elevation angle and azimuth to the jammers for a planar DAA. The calculation of direction for three correlated interferers having different elevation angles and azimuth is performed. The coordinates of the jammers are chosen so that the interference come at the maximum of the side lobes of the radiation pattern of the elliptical DAA. Using the method of the compensating radiation pattern, nulling is performed in the found directions.

The directed use of modern calculation methods in engineering practice makes it possible to take a fresh look at gas flow processes in gas-cooled turbogenerators that are already into operation. This paper introduces the gas cooling system simulation of 300 MW turbogenerator with the gap-pickup rotor for obtaining the detailed gas flow in the ventilation system. Reynolds equations and finite volume method are used for simulation. Based on the numerical simulation results, the valuable distributions of velocity vector in stator and rotor ducts are presented. The explanation of temperature reducing effect of stator winding according to indications of Resistance Temperature Detectors (RTDs) was suggested that locates in the zone of longitudinal gas separation barriers in air gap of generator.

This paper proposes a computer simulation model of a heterogeneous traffic flow which consists of personal and public transport i.e., buses. The road topology is multi-lane and allows a personal vehicle to change lanes. The time evolution of the system is based on Nagel-Schreckenberg cellular automata model. This work illustrates the impact of the location of bus stops on bus traffic characteristics. The new definition of free flow for buses is given. Simulations have shown that the incorporation of buses in a mixed traffic flow has a positive impact on traffic flow. An increase in the number of buses leads to an increase in the average speed of personal cars. However, the average speed of all vehicles has a maximum at a certain ratio between passengers of buses and personal cars. Since the position of this maximum is not the same as for individual types of agents (buses or personal vehicles) this allows one to introduce the social dilemma.
