#2 / 2023Biological SciencesPanesh O.A., Chernyavskaóa I.V., Chitao S.I.Promising essential oil plant species of the Celery family Apiaceae in the flora of Adyghea
The article discusses promising essential oil plant species of the Celery family of the Republic of Adyghea, the yield of green mass and the yield of essential oil. While doing the research, the following species were identified as promising essential oil plants: Visnaga daucoides Gaertn, Pimpinella saxifrage L., Archangelica officinalis Hoffm., Laser trilobum (L.) Borkh., Levisticum officinale Koch., Seseli transcaucasicum (S.) Pimenov & Sdobn., Foeniculum vulgare Mill. Dur-ing the experiment all the studied species showed good adaptation to the conditions of the foot-hill zone of Adyghea, showed high viability and did not suffer from any diseases. The most developed species in local conditions are Archangelica officinalis, Foeniculum vulgare and Seseli transcaucasicum. These plants are recommended for essential oil production.
MathematicsRoytenberg V.Sh.On bifurcations of separatrix contours of dynamical systems invariant under a finite group of rotations
The article considers families of vector fields on the plane that are invariant under rotation through angle 2π/n . At zero values of the parameters, it is assumed that the vector field has a contour of rough saddles, different from the origin, and their separatrices, invariant under rotation. In cases of general position, bifurcation diagrams of such families are described.
On self-oscillations of one kinetic model
With the use of methods of qualitative theory of differential equations, the article examines the kinetic model behavior, in particular, the phase portrait on the Poincaré disk. An example of a system with a stable cycle is given.
Technical SciencesTeploukhov S.V., Timakov V.B., Sedoy K.V.Implementation of Arduino Nano microcontroller based PET-plastic filament extruder
The most popular Fused Deposition Modeling (FDM) 3D printing technology requires a large amount of plastic filament. Thus, it is reasonable to create a special device – filament extruder for forming filament from PET products. The proposed solution will allow to process plastic into a bar with a constant diameter of 1.75 mm. To implement it, a circuit diagram of the device was built. 3D printing of the spool, on which the filament is wound, as well as a program for micro-controller Arduino Nano, which you can use to change the parameters of the device such as the temperature of the nozzle heating and the winding speed of plastic, was made. As a result, a working prototype of the extruder was created, with the help of which a number of experiments were conducted, which made it possible to obtain the optimal parameters of the device function-ing. The comparison of the obtained filament with the industrial sample is performed. The pro-posed PET plastic filament extruder can significantly increase the economic efficiency of 3D printer.
Secure data exchange organization between the corporate network and the public network
The article provides analysis of tools for switching shared storage devices between information systems of different categories. Examples of the implementation of promising tools based on the components made in Russia are provided. The authors provide solutions to reducing the cost of eliminating information security threats and cases when the use of traditional means of ensuring information security are not enough to guarantee the protection of the information infrastructure.
Development of hardware and software complex for diagnosing facial muscles in people with infantile cerebral palsy
The aim of the project is to develop a set of hardware and software to identify problems in the muscles of the speech apparatus, which will allow to transform a massage aimed at relaxing these zones into a more targeted and effective one. The implementation of this project will re-duce the influence of the human factor on diagnostic results, simplify the diagnostic process and, as a result, improve speech functions and socialization of a person in society. The authors provide a software concept with the use of artificial intelligence and neural networks, as well as a hardware diagnostic complex.
Methods and means of ensuring guaranteed disconnection of circuits (lines) of equipment possessing acoustoelectric conversions (microphone effect)
The article considers the main existing certified means of ensuring the security of acoustic speech information circulating in the protected room. An analysis of their applicability in mod-ern auxiliary technical means for protection against visual and acoustoelectric channels of in-formation leakage is conducted. Technical solutions for equipping digital devices containing speakers, microphones, and web cameras are proposed. The parameters for evaluating the effectiveness of means of guaranteed circuits (lines) disconnection, the formulas for their calculation, and the procedure for conducting measurements are discussed.
Analysis of the relevance of the use of collaborative robots for the production process of renewable energy components
The aim of the study is to review and analyze the use of devices related to collaborative robotics in the production of components for renewable energy sources – an industry that is in the trend of global energy movements. Particular attention is paid to the consideration of the use of collaborative robots in the production of renewable energy components.
Evaluation of mobile application performance
The aim of the article is to study computational offloading in mobile applications in order to evaluate their performance. The main attention is paid to the analysis of the influence of architecture, the use of device resources and computing time in mobile applications. Experimental results, which show that usage of computation offloading significantly speeds up the execution of complex tasks in mobile applications, thus increasing their performance, are presented. The article provides a brief analysis of how resource usage and execution time vary with the complexity of the task, which can be useful for developers of mobile applications to choose the best application architecture.
Module for monitoring technological parameters of renewable energy converters
Nowadays many countries use various technologies for converting renewable energy sources (RES) in order to increase the level of energy production and reduce the amount of harmful emissions into the atmosphere. The use of renewable energy sources is accompanied by various problems, one of which is the need to assess the amount of energy produced to determine the effectiveness of the introduction of a specific renewable resource type. To solve this problem, various forecasting models are used, the construction of which requires arrays of various data: information on energy production from existing power plants based on RES, theoretical values of RES capacity in a particular region, meteorological data, technical characteristics of energy converters. Since the technological characteristics of specific converters are located most often on the website of manufacturers and sellers, and taking into account the constantly emerging new converter elements with greater power and efficiency, it is necessary to use the most relevant data to correctly predict the amount of energy produced, which requires periodic monitoring of emerging technological solutions. In this regard, in this paper it is proposed to consider the process of creating a module for automated search and collection of the main technological parameters of RES converters using web-scraping data collection technology.
