Since the amplitude of the CPT resonance critically depends on the intensity and position of the spectral components of the pump radiation, it is necessary to control the parameters of these components, which are usually recorded in digital form. This paper describes a fundamentally new method for processing the laser emission spectrum recorded with a scanned Fabry – Perot interferometer (FPI), based on using the experimentally recorded transmission form of the scanned FPI as a reference spectral component. The paper presents examples of processing the experimentally recorded radiation spectra of a diode laser with an external resonator under microwave modulation of its injection current. The error of processing by the proposed method turned out to be approximately an order of magnitude smaller than when processing by the well-known Airy formula describing the transmission of the FPI. This is explained by the fact that the Airy formula is valid for light beams whose wave front curvature is consistent with the curvature of the IFP mirrors, which is often not true in the case of a real experiment. The method can be used to process the spectra of modulated radiation of various types of lasers, which is an important task in detecting CPT resonances and further creating quantum frequency standards based on them.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135427200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Video surveillance systems have become an integral part of everyday life. Cameras are installed in apartment buildings, public places, even in apartments and private houses. However, one of the most important areas where computer vision has found significant application is the observation of biological objects and analysis of their behavior and state, especially in the context of nature protection and automation of animal behavior research. With the growth of quality and quantity of video materials, the problem of accurate and efficient methods for classifying objects in real time becomes relevant, especially when it comes to automatic monitoring of animal condition. There can be no mistakes here, so it is necessary to use only the latest technology. This paper describes the main types of object recognition, considers popular modern neural network architectures, and performs a comparative analysis of some of them in relation to the problem to be solved. In the course of work using methods of additional processing and image annotators SuperVisely and VGG Image Annotator, a dataset with more than a thousand unique images for extraction of relevant characteristics of objects was formed, and experimental studies of the quality of object recognition on video using pre-trained known neural network models were carried out. The requirements to the initial data for effective solution of the problem of automatic monitoring and prediction of the condition of biological objects have been defined and formulated. It is shown that in order to avoid the appearance of blind zones in the animal habitat it is necessary to use a sufficiently large number of cameras placed with overlapping of the investigated space so that the monitoring objects were constantly in the field of visibility. This will subsequently make it possible to compile an overall high-resolution picture made up of images from all cameras and on the basis of the obtained picture to classify objects using artificial neural networks.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135427206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, all known devices for high-frequency electromagnetic destruction at a frequency of 27.12 MHz are used for superficial shallow operations (removal of papillomas, moles, etc.). The development of a high-frequency electromagnetic system for the destruction of deep, dense tissues (bone, cartilage), as well as malignant neoplasms at the indicated frequency, is the most urgent task of our time. To conduct research at the indicated frequency, an experimental setup was developed and implemented on a modern element base, a distinctive feature of which is ensuring stable and reliable operation of the used transistor power amplifiers while maintaining their performance in a wide range of load changes (from idle to short circuit). This feature is implemented through the use of a two-channel bridge amplifying path. To test the operability of the installation, a multimeter with a thermal imager function and an immitance meter were used. The form of the output signal of the installation is a sinusoid, the second harmonic is weakened in relation to the main one by 60 dB. The studies were carried out in vitro on biopsies of muscle, bone tissues and liver of cattle, as well as on pig skin. It is shown that cuts of a biological tissue made at a frequency of 27.12 MHz have deep coagulation, and at a frequency of 13.56 MHz, carbonization of muscle tissue is already observed at the site of coagulation; the destruction of a bone tissue and liver at a frequency of 27.12 MHz is more pronounced, at a frequency of 13.56?MHz, elements of carbonization appear in the area of destruction. The exposure to high-frequency radiation at a frequency of 27.12 MHz occurs with a smaler effect on surrounding tissues than at a frequency of 13.56 MHz, Punctures of muscle tissue and liver performed at various frequencies practically do not differ; the temperature in the electric discharge region, which occurs at a frequency of 27.12 MHz at a radiation power of 30 W, is above 150 ° C (at a frequency of 13.56 MHz the temperature is 126 ° C).However, the temperature in the discharge region at a frequency of 27.12 MHz can be reduced to the same temperature as at a frequency of 13.56 MHz by reducing the power of electromagnetic radiation by a factor of 1.5.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135426862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, in some cases, it is necessary to consider systems of a discrete type. An example of the synthesis of an automatic control system for an accurate positioning of a table driven by a direct-drive motor is given. Such systems provide accurate positioning in the processes of manufacturing and processing of parts. They are used in various fields of industry: medical, aerospace, automotive and others. In particular, the above model of the precise positioning table is used for packaging semiconductor elements. A feature of this example is the representation of the transfer function of the object model in a discrete form and the presence of four-cycle delay links in it. In addition, this model is unstable due to the presence of poles lying on the stability boundary in it. As a synthesis method, a modal method is used, using a polynomial decomposition of the transfer function of the model of the control object and controller. An approach is also demonstrated that makes it possible to reduce the number of calculations in the synthesis of regulators by reducing the order of the transfer function of the considered object model and reducing the number of unknown parameters of the regulator. At the same time, a regulator is obtained that differs from the original one. Various options for choosing the desired poles of the transfer function of a closed system are analyzed. The choice of the desired poles is carried out in favor of reducing the amount of overshoot of the system relative to the transients of the system with the initial choice of poles.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135427052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A four-stage calculation algorithm has been developed, in which the first stage determines estimates of the resource value of OCW in storage facilities. At the second and third stages, estimates of the resource potential of combinations of \"OCW storage - recycling technology\" are calculated taking into account constant and variable economies of scale, respectively, as well as the effect of scale (constant, increasing or decreasing), which characterizes the qualitative assessment of the scale properties of objects of the OCW recycling system. At the fourth stage, an assessment of the effectiveness of scaling, which characterizes the magnitude of the impact of scale of technological operations on the efficiency of OCW recycling in the analyzed system, and the optimal sequence of processing of OCW in storages by the criterion of increasing the resource potential of the system objects, taking into account indicators of scaling, is determined. By the example of the system of OCW recycling in the Samara region estimates of resource value of OCW in storages, assessment of resource potential of combinations \"OCW storage – recycling technology\" and corresponding indicators of scaling (effect of scale and evaluation of scaling efficiency) have been calculated.

For example, a stabilized platform on a ship is used to accommodate navigation equipment and antennas of radar communication systems, which improves the efficiency of this equipment under the influence of wave disturbances. There are various kinematic schemes for building ship stabilized platforms. In particular, serial stabilized platforms and parallel stabilized platforms are used. In practical applications, serial stabilized platforms have found wider use. In this paper, we consider a mathematical model of a ship-based stabilized platform with two degrees of freedom, where the angular orientation of the platform is controlled using electric hydraulic drives. The use of electro-hydraulic drives makes it possible to ensure the formation of the required magnitude of the force effect to compensate for disturbances from wave oscillations of the ship's deck. In order to obtain relations for describing the relationship between the angular displacements of the elements of the kinematic scheme of the platform and the displacement of the hydraulic cylinder rod, the apparatus of complex numbers is involved in this work. A mathematical model of an electrohydraulic drive is considered taking into account the dynamics of movement of the electromechanism of a spool servo valve, the flow rates and pressures of the working fluid in the cavities of the hydraulic cylinder. A linearized mathematical model of an electrohydraulic drive is considered, and estimates are obtained for the parameters of the obtained mathematical model for given mass-dimensional characteristics of an electrohydraulic drive. This mathematical model can be used in the synthesis of an electric hydraulic drive control system to provide a given angular orientation of the platform under the action of wave disturbances.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135427043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an idea is an alternative approach to the one using Poya's enumeration theorem, including Burnside's lemma. The relationship between partitions of numbers and permutation types is shown. Disorder types are associated with necklace types considered as permutations in which no element remains in place, as well as with disorders with fixed elements. The distributions of disorders by types for necklaces up to the seventh degree are studied. The number and enumeration of disorders of each type is carried out, and their evenness is established. Particular attention is paid to the study of the symmetric necklaces properties. Classes of symmetry and asymmetry are enumerated for each necklace type considered. At the same time, the concepts of chiral and achiral symmetry are introduced as varieties of axial symmetry. Relationships between the power of symmetry classes and the order of symmetry of necklaces are revealed. The concept of symmetry diagrams for necklaces is introduced. Diagrams could be applied for determining the properties of invariance of symmetric and asymmetric necklaces of a given length. The concept of congruence is used as an equivalence relation between necklaces. It allows implementing a geometric approach to the study of necklaces and the visualization of the results obtained. For this purpose, necklaces are associated with multiconnected non-oriented graphs, the vertices of which are the vertices of regular polygons. In this case, the number of vertices in the graph corresponds to the necklace’s length, and the number of connected components coincides with the number of bead colors. As an application of the results obtained, the possibility of studying the accent dynamics of poetic stanzas vertically using necklaces is considered. Empirical data on the use of various types of seven-line stanzas in poetic practice are presented. It is noted that approximately a quarter of the existing symmetric types of necklaces for various reasons do not find practical application.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135428528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed systems register the visible and infrared spectra. Various methods of microscanning with the developed multispectral matrix photodetectors are proposed. Two colors are recorded in each cell, which simplifies the interpolation process, and using the microscanning technology, can eliminate it. For the obtained subpixels, the interpolation algorithm is reduced. In this case, the direction of a matrix shift should be taken into account when performing microscanning. For staggered cell patterns, the choice of direction is not as critical as for pseudo-random or vertical/horizontal arrangement. When microscanning, the direction of matrix shift should be taken into account. For staggered cell patterns, the choice of direction is not as critical as for pseudo-random or vertical/horizontal arrangement. So, for example, a pseudo-random arrangement is suitable for recording images of nature, where there are many small details of various shapes; and vertical/horizontal arrangement is suitable for scenes of the city and industrial areas, where everything has clear vertical and horizontal lines. The very idea of microscanning with a shift of half a pixel makes it possible to fill the \"blind\" zones of the matrix - pixel binding - on four sides of the pixel itself, which leads to a 4-fold increase in color resolution. For the obtained subpixels, a linear or adaptive interpolation method is suitable. It is also possible to take a more complicated path and choose bicubic, biharmonic interpolation. However, this approach contradicts the very concept of simplifying the image processing algorithm, although it leads to high-contrast color resolutions. Such systems can be used in surveys where it is necessary to record the exact details of a terrain or object, for example, in aerial photography and photogrammetry.","PeriodicalId":471395,"journal":{"name":"Sistemy analiza i obrabotki dannyh","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135427208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Induction heating is an efficient and economical way to provide uniform and rapid heating of a liquid without the need for direct contact with the heating element.

The design of induction devices for heating a liquid medium requires taking into account many factors, such as the properties of a liquid, the parameters of the induction coil, the type of power source, and others. One of the main advantages of induction heating is the ability to precisely control heating and its efficiency, which can reduce energy costs and increase the productivity of production processes. In this regard, the design of induction devices for heating a liquid medium is of great importance in modern industry and science, allowing an increase in the productivity and quality of production processes, as well as reducing energy costs and improving production safety. This article proposes a general structure of the software and hardware for an induction device for heating a liquid medium. A mathematical model is proposed for calculating thermal and electromagnetic processes in the considered induction installation. An experiment was carried out with a choice of factors of interest, the formulation of objective functions using the theory of experiment planning to obtain regression relations for the synthesis of an inductor, as well as the composition of optimization procedures implemented by the microcontroller software, and to substantiate the need for identification procedures.
