  • The article is devoted to the analysis of the behavior of a mobile robot using finite state machine algorithms in order to find a way to the goal and avoid obstacles. After justifying the use of such methods, the analysis of a standard deterministic finite automaton is done. Further, the theory of Markov processes is applied to this algorithm, as a result of which the state machine becomes part of the hidden Markov model. This allows you to apply probabilistic methods to modeling the behavior of the robot. This probabilistic behavior is most promising in complex environments with unpredictable obstacle configurations. To compare the efficiency of deterministic and probabilistic finite state machine, we applied a genetic algorithm. In the numerical experiment that we conducted in the Scilab software, we considered two main types of environments in which a mobile robot can move - an office-type environment and a polygonal-type environment. For each type of environment, we alternately applied each of the indicated behavior algorithms. For the genetic algorithm, we used one hundred individuals who were trained over 1000 generations to find the most optimal path in the specified environments. As a result, it was found that the deterministic finite state machine algorithm is the most promising for movement in an office-type environment, and the probabilistic finite state machine algorithm gives the best result in a complex polygonal environment.

Experimental studies of radiation effects on FRAM chips
  • 1Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The work is devoted to the study of radiation effects on FRAM memory chips. The effects of heavy charged particles entering the microcircuits are considered, the results in static and dynamic modes are analyzed. In statistical mode, the sensitivity of FRAM did not show any dependencies on the data pattern, but showed a relationship with fluence. In dynamic mode, the order of access to memory cells does not affect the sensitivity of memory. The dependences of the consumption current on the radiation dose and the annealing time after irradiation are given. An effects map is shown showing a two-band area sensitive to the laser. According to its relative area, this is the peripheral logic of the device. Studies have confirmed the usefulness of only a few effect maps. This is consistent with the results of tests for exposure to heavy charged particles.

  • The paper deals with the behavior of field-effect transistors under the influence of radiation. The structure of tunnel field-effect transistors, the principle of operation, various effects from exposure to ionization radiation from outer space, and the results of experimental studies of resistance are presented. Field-effect transistors based on single-layer materials such as graphene and MoS2 are also considered. The behavior of field-effect transistors based on graphene is simulated. The paper presents current-voltage characteristics before and after irradiation, at positive and negative voltage at the transistor gate, etc., the analysis of which showed that there were significant changes in the electrical characteristics of transistors and the surface morphology of a single-layer material. The appearance of defects is associated with the heating of the material in the center of the particle track. Similarly, the simulation of the behavior of transistors based on nanotubes, when exposed to radiation, single events appear, was carried out.

Research and development of a model for assessing the optimal location of pedestrian crossings based on a conflict model

  • With the increase in the number of vehicles, the number of conflict situations between pedestrians and cars increases - the number of accidents increases. The study of walking behavior and the relationship of behavior with the location of pedestrian crossings will allow you to find the optimal solution for a pedestrian crossing. The proposed model for assessing the optimal location of pedestrian crossings based on the pedestrian -vehicle conflict model is based on three indicators: the likelihood of a conflict between a person and a vehicle, the severity of the accident and the expected number of conflicts. The model was developed in order to determine the optimal location of pedestrian crossings and to study the conflict between pedestrians and vehicles at unregulated pedestrian crossings. In order to take into account the pedestrian behavior in the proposed model, modeling was carried out using the SPSS software. Regression analysis formed the basis for modeling pedestrian behavior, and a model of a "bad solution" for an unregulated pedestrian crossing was obtained. To verify the reliability of the model and the accuracy of the forecast, a Hosmer-Lemeshowe test for suitability and an omnibus test of model coefficients were conducted. The overall accuracy of the model prediction was 97.6%, the accuracy rate with "bad behavior" is 95.7%, and the accuracy rate without "bad behavior" is 99.4%.

  • The place of rescue activities is considered, as well as the scheme for exchanging messages with services in the event of a fire. The features of preparation for localization of fires by fire departments are outlined. The organization of fire suppression by personnel prior to the arrival of fire departments is considered. As an object of protection, the object of mass stay of people is considered on the example of the cinema and concert hall "October" in Lipetsk. The calculation of the required number of forces and means for extinguishing a fire on the roof of the protected object was carried out. Schemes have been developed for deploying forces and means for extinguishing the roof and deploying to extinguish a fire on the roof of the facility. The substantiation of the application of the main fire safety systems for the object of mass stay of people is carried out. Improvement and substantiation of fire extinguishing measures using water fire extinguishing systems was carried out. A schematic diagram of the internal fire-fighting water supply of the object of protection has been developed. Substantiation and application of photoluminescent evacuation systems is carried out. It is proposed to propose to install the main elements of fire extinguishing systems, which will ensure the response time of the main forces and means for the elimination of emergencies, as well as coordinate the main measures for the evacuation of the affected population from this facility.

  • For the considered groups of structures - metal trusses, beams, columns, landings and marches of a multi-storey frame building, a continuous visual and detailed instrumental examination was performed. For load-bearing structures, verification calculations of their bearing capacity were performed. Based on a comparison of the defects identified during the inspection and the results of verification calculations, an assessment of the technical condition was made for individual structures, for each group of structural elements, as well as for the building as a whole. For structures with defects and damage, recommendations are given for their restoration and repair. Additional damages and defects were recorded, the appearance of which is associated at the object under study due to a forced break in the production of construction work. The results of surveys and calculations showed that the technical condition of landings and marches can be considered generally efficient. The results of the verification calculation showed that the technical condition of the metal columns as a whole can be considered efficient. The results of the verification calculation on the computer of metal truss structures are presented in the form of a mosaic and diagrams of internal forces. When performing verification calculations, the finite element method was applied.

  • The article considers a risk assessment matrix, according to the authors, it is the basis for modeling the risks of implementing project management for the development of meat processing enterprises. This matrix is developed in accordance with the structural ideas about the project management of the development of industry organizations as a system, it is proposed to use it in conjunction with the Gartner curve, based on the division of the resulting groups according to the degree of riskiness of their innovative projects. In accordance with the methodology proposed by Gartner, in order to make the right decision about when to implement a particular project, the main issues that companies need to balance when developing a technology maturity cycle curve are formed. The project management is considered from the point of view of the formation of a single information environment. A model for the implementation of several projects of a meat processing industry company was built using the @RISK software product. The advantages and disadvantages of deterministic and stochastic risk analysis based on Monte Carlo modeling are described. Given that each project has a 5% chance of failure in any given month, a summary graph of monthly costs is shown. As a result of running the simulation, the total costs of the project are presented.

  • Irrigation is one of the main technological processes in greenhouse farming, which essentially provides qualitative and volumetric indicators of produced products. Thus, the combined irrigation technology which combines low-volume methods of drip and aerosol irrigation is widespread. We consider the combined irrigation system which includes an installation for water electro-chemical activation (ECA). Extended abilities of this system are caused by the reactivity of catholyte and anolyte, which are metastable products of water ECA. Catholyte and anolyte are used as growth stimulator and antiseptic respectively in the plant cultivation. Automation of the combined irrigation system, in addition to resource-saving, is also aimed to prevent technological modes violation due to the subjective (“human”) factor. Control algorithms for drip and aerosol irrigation with ordinary water, drip and aerosol irrigation with catholyte and aerosol irrigation with anolyte are described in the article. When the algorithm starts, the control testing is performed to detect possible failures in the irrigation system (for example, rupture of drip tubes or salting of drippers). In case of a detected issue, a diagnostic message is shown and accompanied by a sound signal. More complex technological irrigation modes associated with the use of catholyte and anolyte also include the performance monitoring of the water electrochemically activation unit. The control of the irrigation technological parameters (soil moisture, air humidity, soil pH) is carried out by retrieving the relevant sensors data and comparing the obtained values with the set ones. When the set points are reached the relevant technological links (electric pumps and electromagnetic valves) are switched off by the signal of the microcontroller. The presented algorithms are designed for developing the microcontroller control unit software for the combined irrigation system.

  • The article is devoted to the study of radiation effects on non-volatile memory. The basis of non-volatile memory with high speed is the ferroelectric effect. The paper describes the principle of operation of FRAM memory, considers the characteristics of various options for the implementation of FRAM. Particular attention is paid to the description of experimental studies of the resistance of FRAM to the effects of ionization radiation from outer space. PZT-FRAMs from three manufacturers, Krysalis Corporation, National Semiconductor Corporation, and Sandia National Laboratories, were considered. The paper illustrates the dependences of the switching charge under the influence of X-rays, the charge change during irradiation and annealing at low temperatures, plots of Hysteresis loops, etc. The influence of neutrons on PZT FRAM was studied by measuring the total switching charge observed when measuring the Hysteresis loop; residual charge; effect on repeated read/write cycles. The experiment involved three samples with different PZT films 240, 250, and 400 nm thick.

  • The paper discusses the issues of ensuring the stability of non-volatile memory under radiation exposure. Experimental studies of the durability of memristors were carried out. The switching mechanism on TaOh memristors is similar, but not identical to the TiO2 memristor. X-ray data showed that the "off" state is most susceptible to radiation damage, therefore, before gamma irradiation, all devices were reset to the "off" state. After the irradiation sequence was completed, an installation/reset cycle was performed. For example, graphs of reading I-V curves showing a slight change in slope are constructed. The setting/reset changes are in the range of observed electrical oscillations in the device between cycles, so it cannot be unambiguously attributed to gamma irradiation. When irradiated in static mode with a LPE of 70 MeV * cm2 /mg, single effects were not observed, but in dynamic mode they were.

  • This review article discusses methods for measuring the main mechanical properties of thin films: tensile testing, indentation, evaluation of the mechanical strength margin for the curvature of the plate-thin film system, bulge method and research using a deformed and resonant cantilever. In the process of critical analysis of domestic and foreign literary sources, the advantages and disadvantages of the methods were revealed; the authors' motivation for conducting such studies was explained. In addition to the existing widely used methods, an original and relatively new technique is given - the use of electric current as a controlled means of applying thermo mechanical stresses to electrical conductors to characterize their fatigue behavior. Approaches for increasing the mechanical strength of thin films are also indicated.

Evaluation of the effect of crystal structural features on the resistance of DMOS transistors to ionizing radiation
  • 1 Voronezh Plant of Semiconductor Devices - Assembly

  • The work is devoted to the study of the influence of the structural features of the crystal on the resistance of DMOS transistors under the influence of ionizing radiation. A comparison of the results of instrumentation and technological modeling of commercially available p-channel DMOS transistors designed for the maximum allowable drain-source voltage of 60V and 100V is carried out. Modeling was carried out in the TCAD environment, all the basic physical principles of the structure under study were taken into account with the help of appropriate mathematical models. The obtained values of the model's electrical parameters showed full compliance with the normative values. The critical points of the crystal design that affect the performance of transistors in the presence of ionizing radiation from outer space are determined. The influence of the electric field strength in the crystal body on the resistance to ionizing radiation is estimated. It is shown that the actual values of the electric field strength in the region of the p-n junction do not exceed the values of the critical strength, having a margin of more than 1.22 times.
