Device discovery and identification in industrial networks
Authors: Biß Klaus , Kippe Jörg , Karch Markus
Published: September 2023

The Act on Federal Office for Information Security (BSI Act) explicitly mandates the use of attack detection systems. The BSI works together with operators of process plants as well as discrete manufacturing facilities in order to test sensors, which may be part of such systems, in their networks. This gives the BSI the opportunity to record a collection of network traffic from those plants. One goal is to improve the detection and characterization of devices in industrial networks by implementing new or enhanced features for the open source network monitoring tool suite Malcolm. In this context, the recording of the network traffic represents the starting point for further investigations. This paper highlights what needs to be considered in these recordings to serve as a basis for device identification and characterization.

Published: September 2023

In this article, ZnO quantum dots (QDs)-g-C3N4 complexes were prepared by a combined sol–gel method and ultrasound-assisted chemical method, and ZnO-g-C3N4 composites with different doping ratios were also prepared for photocatalytic degradation of dye wastewater. The composites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffractometry, Fourier transform infrared, X-ray photoelectron spectroscopy, diffuse reflectance spectroscopy, and photoluminescence. The photocatalytic performance of the best ZnO QDs-g-C3N4 complexes with different g-C3N4 doping amounts was investigated, and the kinetics of their photocatalytic reactions were analyzed, and it was found that the best effect of ZnO-g-C3N4 10% could reach 89.08% and ZnO QDs-g-C3N4 could reach 91.53%. It was also demonstrated that ZnO-g-C3N4 10%, ZnO QDs-g-C3N4 cyclic stability is better, and the reaction mechanism of ZnO QDs-g-C3N4 was investigated. It can be used for the degradation of dyes in environmental wastewater and the removal of harmful substances from the natural environment.
Muslim personal names in Urdu: structure, meaning, and change
Authors: Ahmad Rizwan , Kulikov Vladimir , Iqbal Noorin
Published: September 2023

Based on an analysis of a corpus, in this study we examine: (a) the linguistic structure of Muslim personal names, (b) their etymological sources, and (c) some changing patterns among the younger generation. Firstly, we present a typology of the naming patterns by showing that there are four major types – one-part, two-part, three-part, and four-part names. While one-part names are formed from the given name only, the other three types are complex as they are composed of additional names containing honorific titles, caste titles, patronym, and husband’s names in case of married women. Secondly, by examining the linguistic sources of one-part and two part names, we show that Muslim names are primarily derived from Arabic and Persian. Our study further shows that while Indian Muslim names trace their origins to Arabic, the structure of their names differs significantly from Arabs and other Muslims especially those in southern India. Finally, we demonstrate a shift in the naming pattern among the younger generation in that some names and honorific titles are declining. We conclude our paper with some possible social factors that may contribute to the shift.
Right, Morals and the Categorical Imperative
Authors: Tomassini Fiorella
Published: September 2023

In this paper I examine the relationship between the principle of right and the principle of morals [Sitten] in Kant’s Metaphysics of Morals. My interpretation denies that the principle of right is derived from the categorical imperative, but neither does it adhere to the independence thesis. I present a third way of understanding the relationship between the law of right and the universal law of morals: the latter is needed in order to formulate the former, but it is not sufficient. The principle of right is obtained by applying the categorical imperative to the concept of right. I highlight the discussion on the subject within the late eighteenth-century German natural law tradition and similar arguments found in Achenwall.
Theory of nonlinear corner states in photonic fractal lattices
Authors: Ren Boquan , Kartashov Yaroslav V. , Maczewsky Lukas J. , Kirsch Marco S. , Wang Hongguang , Szameit Alexander , Heinrich Matthias , Zhang Yiqi
Published: September 2023

We study linear and nonlinear higher-order topological insulators (HOTIs) based on waveguide arrays arranged into Sierpiński gasket and Sierpiński carpet structures, both of which have non-integer effective Hausdorff dimensionality. Such fractal structures possess different discrete rotational symmetries, but both lack transverse periodicity. Their characteristic feature is the existence of multiple internal edges and corners in their optical potential landscape, and the formal absence of an insulating bulk. Nevertheless, we show that a systematic geometric shift of the waveguides in the first generation of such fractal arrays, which affects the coupling strengths between sites of this building block as well as in subsequent structure generations, enables the formation of corner states of topological origin at the outer corners of the array. We find that, in contrast to HOTIs based on periodic arrays, Sierpiński gasket arrays always support topological corner states, irrespective of the direction of the shift of the waveguides, while in Sierpiński carpet structures, corner states emerge only for one direction of the waveguide shift. We also find families of corner solitons bifurcating from linear corner states of fractal structures that remain stable practically in the entire gap in which they form. These corner states can be efficiently excited by injecting Gaussian beams into the outer corner sites of the fractal arrays. Our results pave the way toward the investigation of nonlinear effects in topological insulators with non-integer dimensionality and enrich the variety of higher-order topological states.
The Extra Calvinisticum and the Question of Where God Is
Authors: McFarland Ian Alexander
Published: September 2023

This paper maintains that at the heart of the post-Reformation debates over the extra Calvinisticum lies the question of what it means to name God’s presence in the world – that is, to say where God is. Because the Lutheran position insists that there can be no proper identification of God’s presence in the world that does not take its bearings from talk about Jesus’ presence, it serves as a means of preventing Christian God-talk from becoming detached from the flesh-and-blood realities of human existence. In this way, the denial of the extra Calvinisticum is a corollary of a theology of the cross – that is, the principle that talk about God is normed by the concrete reality of Jesus. At the same time, the Lutheran genus maiestaticum is rejected as making just the sort of move to which Luther himself objected in the doctrine of transubstantiation: a metaphysical explanation of Jesus’ presence in the world rather than a simple appeal to miracle.

Iron-based coagulants are widely used in wastewater treatment due to their high positively charged ion that effectively destabilise colloidal suspension, and thus contribute to the formation of insoluble flocs. Ferric chloride, ferrous sulphate, and poly-ferric sulphate (PFS) are examples of iron-based coagulants that are highly available, and are beneficial in producing denser flocs, thereby improving settling characteristics. This work aims to review the preparation methods of PFS and critically discuss the influence of these methods on the PFS properties and performance as a chemical coagulant for water and wastewater treatment. In polymeric form, PFS is one of the pre-hydrolysing metallic salts with the chemical formula [Fe2(OH)n(SO4)3−n/2]m(where,n < 2,m > 10) and has a dark brownish red colour as well as is more viscous and less corrosive. PFS has an amorphous structure with small traces of crystallinity, containing both hydroxyl and sulphate functional groups. It has been applied in many industries including water or wastewater treatment which is also discussed in this study. It has the ability to remove pollutants contained in water or wastewater, such as turbidity, colour, chemical and biological oxygen demand, phosphorus, and others. This study also provides a review on the combination of PFS with other chemical coagulants or flocculants in the coagulation/flocculation process, and also flocs formed after a more stable treatment process.

Authors: Laerkner Eva , Bendix Laila , Jäger Madalina , Hansen Maj-Britt , Vaegter Henrik Bjarke
Published: September 2023

Objectives

Smerteinfo.dk is a freely accessible Danish website containing research-based, up-to-date knowledge on chronic pain, written in lay language, with a focus on information, guidance and self-management tools, developed in collaboration between health professionals and persons with high-impact chronic pain. This mixed-method study explored experiences, perceived usability, and challenges of Smerteinfo among patients with high-impact chronic pain.

Methods

Semi-structured interviews enabling thinking-aloud and participant observation while using Smerteinfo were performed in 11 patients with high-impact chronic pain. Survey data were collected three months after being invited to use Smerteinfo among 200 patients on waiting-list at a Pain Center in Denmark.

Results

Three themes captured the depth and variation in patterns of experiences, usability and challenges using Smerteinfo during interviews: 1) Appreciated easy access to new knowledge yet strived for more personalized information, 2) Experienced incentives as well as challenges when navigating the website, and 3) Suggested earlier introduction to the website. Challenges concerned the unknown update frequency of the website, information consisting of mostly text and many links, lack of material to improve self-management and too general information. Survey data revealed that 87 % found the language in the articles easy to understand and 73 % could recognize themselves and their challenges in the articles. A proportion of the respondents reported improved understanding of their pain condition (56 %), improved coping (33 %), and that they had made changes in their everyday life after reading on the website (33 %).

Conclusions

Patients with high-impact chronic pain found Smerteinfo valuable. The results suggest attention towards spreading knowledge of the website to general practitioners, who could introduce the site at an earlier stage of illness. Continuously improving the site and expand the applicable tools based on scientific evidence and in collaboration with end-users are crucial to ensure the usability of the website in the future.
Electrocatalysis of formic acid oxidation on Pt–Ru alloys modified with Pb adatoms
Authors: Spasojević Savković Milica , Kićanović Zoran , Luković Milentije , Spasojević Miroslav
Published: September 2023

Catalytic effect of lead adatoms, deposited at under-potentials, in the oxidation of formic acid on platinum ruthenium alloys was discovered. With increasing the degree of coverage with the lead adatoms, the catalytic activity of Pt–Ru electrodes increases, reaches its maximum and subsequently decreases. No firmly adsorbed intermediates at the Pt–Ru surface were observed at the optimal coverage degree. Then, its catalytic activity is about 200 mV higher than that on pure Pt in the current density range of 10−4 mA cm−2 to 10−1 mA cm−2. Two effects are responsible for the catalysis of formic acid oxidation. The lead adatoms decrease the number of assemblies of few adjacent free atoms of Pt, on which firmly bound intermediates should form. Positive residual charge of lead adatoms improves their interaction with oxy species, placed on the adjacent atoms of ruthenium. The established interaction stabilizes the energetic state of these oxy species causing the increase in their concentration. A larger concentration of the oxy species accelerates oxidation of firmly bound intermediates and thus releases the Pt atoms for the oxidation of subsequent molecules of formic acid.

Ben-Zeev, T, Sadres, E, and Hoffman, JR. Comparison of force measures between start position, transition phase, and midthigh pull with weightlifting performance during Israel National Competition. J Strength Cond Res XX(X): 000–000, 2023—This study compared the relationship between peak force (PKF) and rate of force development (RFD) at isometric start position pull (ISPP), isometric transition position pull (ITPP), and isometric midthigh pull (IMTP) with the snatch (SN), clean and jerk (C&J), and total score (TOT) in 30 national and international Israeli weightlifters (18 men and 12 women). All measures were collected either 1 week before or 1 week after the Israel weightlifting championship. A significant correlation was observed between peak force at all pull positions and performance in the SN, C&J, and TOT for men, women, and both sexes combined (p < 0.001). The correlations were all very strong (e.g., r values all above 0.90) for both ISPP and ITPP, and all weightlifting performance variables, whereas the correlation between IMTP and weightlifting performance ranged from moderate (r = 0.69) to strong (r = 0.89). In addition, significant differences were observed between the correlation coefficient value in ISPP and ITPP with the TOT score compared with the correlations observed in IMTP (z = 0.7, p = 0.046, and z = 1.7, p = 0.049, respectively). Significant differences were also observed in the women group for ISPP for the SN and TOT score compared with the correlation in IMTP (z = 1.72, p = 0.043, and z = 1.75, p = 0.040, respectively). Rate of force development at 250 milliseconds significantly (p values <0.05) correlated with the SN, C&J, and TOT in women (r's = 0.65, 0.68, and 0.67, respectively), and when both sexes were combined (r's = 0.59, 0.61, and 0.60, respectively), but not for the men. Results of this investigation indicated the importance of isometric force capabilities at ISPP and ITPP for weightlifting performance.

Authors: Westbrook Anne L. , Adams Catrina T. , Taylor Joseph A.
Published: September 2023

A feature of student–teacher–scientist partnerships (STSPs) involves students working with scientists for the purpose of helping them learn more about how scientists work and think. Previous research on STSPs has generally focused on identifying the best practices of partnerships and on identifying challenges of these partnerships. The study reported here employed a cluster-randomized trial design to test the effectiveness of the PlantingScience STSP that combines high-quality curriculum, teacher preparation, and online mentoring by professional scientists. The results of the current study show that students who participated in the PlantingScience STSP showed significant improvements in science content knowledge and attitudes about scientists compared with students in the control group. The study sample was highly representative, demographically, to the U.S. population of high schools. These results add to the limited empirical evidence about the effectiveness of STSPs on student outcomes related to science achievement and attitudes.
A Focus on Writing in the General Biology Class
Authors: Devany Emral
Published: September 2023

Writing is a high-impact tool that is often used to improve student learning, success, and critical thinking. Science courses typically implement writing in the form of laboratory and/or research reports. To extend the use of writing and use it as a tool to learn biology, both in-class/informal and out-of-class/formal writing assignments were designed. All the assignments focused on two important skills biology students are expected to gain: To compare and contrast biological processes and present and defend an argument. The assignments were implemented throughout the semester with a final, cumulative out-of-class assignment to give students an opportunity to review whole class material. The assignments were used in in-person, hybrid, and online General Biology I course at a community college. These assignments can be used as is, modified by the instructor, or used as preparation for valuable classroom debates.
Race, Gender, and the Colonial Orchestral Body at the New Zealand International Exhibition, 1906
Authors: van Rij Inge
Published: September 2023

The orchestra that participated in the opening ceremony of the New Zealand International Exhibition held in Christchurch in 1906 played a central role in signaling what officials described as “nationhood achieved,” as the country marked its move from British colony to dominion. This contribution to nationhood was negotiated through acts of exclusion as well as empowerment, particularly in relation to gender and race. Exhibition officials sought to ban women from participation in the orchestra, demonstrating the tenacious rhetoric of masculinity prevalent in orchestras of the period. Although women eventually overcame this ban, New Zealand’s Indigenous Māori population remained barred from self-representation on the exhibition stage, instead performing their culture as ethnological entertainment beyond the concert hall. At the exhibition’s opening ceremony, it was the orchestra that represented Māori; in the third movement of the Exhibition Ode composed for the event by the orchestra’s conductor, New Zealand composer Alfred Hill, the orchestra performed “in the time of a haka” (Māori war dance). Drawing on an examination of archival material pertaining to the exhibition and analysis of the haka movement, this article argues that the performance of Hill’s haka movement by both women and men in the exhibition orchestra was an act of “brownface” in which the empowerment of the white women of the orchestra was complicated by questions of appropriation and assimilation. Examining the haka movement as event and score illuminates both the role of women in colonial cultures and the colonizing practices of orchestras themselves.
Creep behavior and prediction of fiber-reinforced polymer reinforced timbers under changing temperature and relative humidity
Authors: Lee In-Hwan , Song Yo-Jin , Hong Soon Il
Published: September 2023

The creep behavior of fiber-reinforced polymer (FRP) reinforced larch laminar timber was studied with respect to temperature and humidity fluctuations. There was a control group of larch laminated with two small-diameter timbers with FRP (carbon FRP (CFRP), glass FRP (GFRP)) produced; the laminated lumber had the same cross-sectional area as the two laminated lumber specimens with reinforced tensile parts. A creep test with fluctuating temperature and humidity was conducted by applying a load of 25% of the bending strength of the control specimen. A total of 8 specimens, 2 for each type, were measured for creep deformation at 9:00 am and 6:00 pm daily for approximately 14,000 h. Temperature and humidity fluctuations were measured every hour. The equilibrium moisture content and humidity of the creep test space exhibited a proportional relationship, and the moisture content of each specimen did not show a noticeable correlation with humidity and equilibrium moisture content. The average relative creep was measured as approximately 0.67 for the control, 0.4 for Glulam, and 0.43 for both the CFRP- and GFRP-reinforced specimens. Thus, the creep deformation of all the reinforced pieces was confirmed to be lower than that of the control specimen.

Published: September 2023

The increased incidence of mucormycosis in post covid-19 is due to steroid induced diabetes mellitus. The commonest presentation is acute invasive fungal sinusitis involving maxillary sinus most commonly followed by invasion to local soft tissues and bone structures. It also involves orbit and brain extending from sinuses. Mandible has no direct communication with any of the para nasal sinuses and involvement is extremely rare and seldom reported. We came across four such cases during post covid-19 mucormycosis epidemic. Poor dentitions, ulcerated mucosa, inoculation during dental procedures are the proposed mode of entry of the fungi into the mandible.
Arte y construcción social del paisaje en Peralta de Turrialba
Authors: Sibaja Blanco A. Mario , Blanco Delgado Aaron
Published: September 2023

El paisaje es socialmente construido en la cotidianidad desde el presente con base en los valores y significados que le constituyeron en el pasado y, en tanto herencia, implica la pretensión de recordar a futuro las configuraciones espaciales que le han dado forma y sentido. A pesar de procesos políticos y económicos que potencian la invisibilización de algunos paisajes en particular, el arte bien puede perfilarse como una estrategia para la divulgación y visibilización de códigos culturales sistemáticamente enviados al olvido. Bajo estas ideas se presenta a Peralta de Turrialba como una galería a cielo abierto, donde la comunidad a través del arte procura reivindicar paisajes pretéritos que cobran sentido en el presente, y que son objeto de deseo y de sueños a futuro. El artículo comenta las expresiones artísticas que circundan el parque central de Peralta, entreviendo los valores compartidos en la construcción de un paisaje, imaginarios y presencias/ausencias que se cristalizan en la relación arte-paisaje.
Прагматический потенциал русских деепричастий в нарративе: корпусное исследование сквозь призму переводов
Authors: Уржа Анастасия
Published: September 2023

Прагматические особенности русских деепричастий совершенного и несовершенного вида рассма-триваются в статье в контексте современной теории первого плана и фона нарратива. Объектом изучения становится прагматический потенциал деепричастий, который позволяет им участвовать в формировании стереоскопического пространства текста, конструировать иерархизированную зону фона повествования, выстраивать перспективу нарратива, устанавливая соотношение точек зрения друг с другом.

В статье проанализированы данные российских и зарубежных научных работ о потенциях дее-причастий в сфере ранжирования текстовой информации. Принято считать, что деепричастия формируют зону «фона» повествования, обозначая второстепенные действия и характеристики. Однако сама зона «фона» имеет сложную иерархию в плане значимости, выделенности ее элемен-тов для повествователя и адресата. Деепричастие обладает набором свойств, которые способствуют большему или меньшему «выдвижению» или «затушевыванию» названного им события или явле-ния.

Ряд таких грамматических и смысловых параметров может быть установлен, так сказать, «до тек-ста». Так, в большей степени выделить событие способны деепричастия совершенного вида, обозна-чающие динамические, контролируемые, ограниченные во времени действия, в особенности если они относятся к личному субъекту и присоединяют индивидуализированный объект (Выстрелив в яблоко, Телль улыбнулся). Напротив, такие характеристики деепричастий, как несовершенный вид, непереходность, обозначение длящегося состояния или признака – сопутствуют номинации фоновых явлений, зачастую не выделяемых в качестве отдельных событий (Обломов принимал гостей, лежа на диване).

Также в статье значительное внимание уделяется другой группе параметров, которая выявляется только «в тексте», в ходе анализа корпусных данных (по НКРЯ). Важнейшая характеристика дее-причастий – относительная частотность употребления в форме конверба в сравнении с личными формами. Этот показатель свидетельствует о том, насколько тот или иной глагол склонен к функци-онированию в форме деепричастия, вне зависимости от частотности глагола в корпусе.

На материале НКРЯ в статье исследованы глаголы пяти семантических групп с частотным упо-треблением в форме конверба. Далее, с опорой на материалы параллельного русско-английского подкорпуса НКРЯ и собранного автором поливариантного набора переводов рассказов А. П. Чехо-ва, в статье иллюстрируются прагматические особенности деепричастий от глаголов с различной семантикой. Демонстрируются выявленные в переводах тенденции к изменению или сохранению функций оригинальных конвербов, анализируются эффекты перевода деепричастий с помощью финитных форм, приводящие к изменению перспективы текста, таксисных и каузативных отноше-ний между клаузами.

Полученные данные не только пополняют сведения о прагматическом потенциале русских дее-причастий от глаголов разных семантических групп, но и позволяют повысить качество предпере-водческого анализа произведений русской литературы.
Religion and Marxism: An Introduction
Authors: Tremlett Paul-Francois
Published: September 2023

This concise and accessible introduction brings the writings of Marx and Engels and later thinkers in the Marxist tradition including Althusser, Gramsci, the Frankfurt School as well as Liberation Theologians such as Gutierrez and Maduro, into focus in relation to questions of religion, social change and social justice. Marx was a nineteenth century thinker trying to develop a theory that could explain the dramatic social and technological changes that he lived through. Later thinkers modified and developed key elements of Marx’ theoretical model, with religion – particularly Christianity – providing a vital point of critical self-reflection for thinkers in the Marxist tradition. This book tracks these modifications and developments to Marx’ ideas, and their continuing relevance to contemporary debates about religion, social change and social justice.
Construction of a physical-mathematical model of oscillations of the unbalanced vibrator of the pneumatic sorting table

Published: September 2023

A physical-mathematical model of oscillations of unbalanced vibrators of a pneumatic sorting table as non-stationary oscillations of an impulse-loaded round plate with various options for fixing its contour has been built. The axisymmetric non-stationary oscillations of a round plate supported by a one-sided round base were considered in two ways of fixing its contour, namely, when it is tightly clamped and freely supported. It was assumed that the linearly elastic base resists only compression and does not perceive stretching. It is shown that for certain durations of the transverse force pulse in time, the amplitude of the deflection of the middle of the plate in the direction of action of the external pulse can be smaller than the amplitude of the deflection in the opposite direction. At the same time, in the second case, there is no contact of the plate with the base. It has been proven that this dynamic effect of the asymmetry of the elastic characteristic of the system also applies to bending moments and is more clearly manifested when the contour is freely supported than when it is tightly clamped. For rectangular and sinusoidal pulses, closed-loop solutions of the equations of motion of the plate during its contact with the base and after separation from the base were constructed. Compact formulas were derived for calculating the amplitudes of positive and negative deflections in both directions from the zero position of static equilibrium. Formulas have been obtained for calculating the time it takes for the plate to obtain extreme deflection values, which is achieved due to the selection of a special axisymmetric distribution of dynamic pressure on the plate. Under such a load, the plate simultaneously detaches from the base at all points, except for the contour points, which reduces the nonlinear boundary value problem to a sequence of two linear problems. Numerical integration of the differential equation was carried out to check the reliability of the constructed analytical solutions. Adequacy of the model was proven for the following values of initial parameters: modulus of elasticity, 2.1·1011 Pa; the Poisson ratio of the plate material, 0.25; plate thickness, 7...10 mm; the maximum pressure on the plate, 4·103 Pa; the bending stiffness of the plate, 6402.6667 N·m

Published: September 2023

Determining the best model for the neural network architecture and how to optimize the architecture with the metaheuristic Protis Approach is a subject of the study. A comprehensive investigation and utilization of metaheuristic methods are necessary. These methods aim to solve problems and adapt from the lifestyle of the amoeba protis. In this study, the proposed method modifies the life cycle of the amoeba, which consists of four phases: prophase, metaphase, anaphase, and telophase. These four phases are modified in the neural network architecture to optimize the appropriate number of hidden layers and produce an efficient architecture model. The results show that the protis approach optimized the neural network architecture, especially in generating hidden layers to improve the neural network model. Distinctive features of the results obtained are that the average range of degenerate neurons in the hidden layer is 0 to 35 neurons in each layer. The standard number of neurons makes it possible to solve the problem of determining the best model on the neural network architecture. The protis algorithm embedded in the protis recurrent neural network for categorical data measurements produces an average RMSE value, representing the difference between actual measurements and predictions, equal to 0.066.
Consequently, the developed model surpasses the current classical neural network model in terms of performance. Regarding accuracy, the protis algorithm embedded in the neural network for categorical and time series data achieves an average precision of 0.952 and a recall of 0.950. The protis convolutional neural network achieves an accuracy of 95.9 %. Therefore, from the three tested datasets, the protis convolutional neural network exhibits the highest accuracy value

The problem of multiple zones in computer vision, including pattern recognition in the agricultural sector, occupies a special place in the field of artificial intelligence in the modern aspect.
The object of the study is the recognition of weeds based on deep learning and computer vision. The subject of the study is the effective use of neural network models in training, involving classification and processing using datasets of plants and weeds. The relevance of the study lies in the demand of the modern world in the use of new information technologies in industrial agriculture, which contributes to improving the efficiency of agro-industrial complexes. The interest of private agricultural enterprises and the state is caused by an increase in the yield of agricultural products. To recognize weeds, machine learning methods, in particular neural networks, were used. The process of weed recognition is described using the Mark model, as a result of processing 1,562 pictures, segmented images are obtained. Due to the annual increase in weeds on the territory of Kazakhstan and in the course of solving these problems, a new plant recognition code was developed and written in the scanner software module. The scanner, in turn, provides automatic detection of weeds. Based on the results of a trained neural network based on the MaskRCNN neural network model written in the scanner software module meeting new time standards, the automated plant scanning and recognition system was improved. The weed was recognized in an average of 0.2 seconds with an accuracy of 89 %, while the additional human factor was completely removed. The use of new technology helps to control weeds and contributes to solving the problem of controlling them

The way to solve the problem of correcting technological indicators, in particular porosity and moisture content, in extruded protein-fat systems based on soybean, rapeseed, hemp meal, and corn grits is considered. The peculiarity of the work is the substantiation of the rational ratio of the content of moisture and lipids in the raw components of the extrudate, which is an important aspect of rationalizing the composition and improving the texture of innovative extruded products based on the specified raw materials.
The object of the research is technological indicators, in particular the porosity and moisture content of the extruded protein-fat system, depending on the moisture and lipid content in the raw components. A rational ratio of moisture content (10.5...12.5 %) and lipids (3.5...5.0 %) in the raw material for the extruded protein-fat system was determined. The use of refined palm olein as an oil product resistant to oxidative deterioration, which should be added to raw components in order to correct the technological properties of the finished product, is substantiated.
The developed protein-fat system of reasonable composition has an advantage over a commercial similar product in terms of crude protein content (29.0 % vs. 8.2 %), porosity (130.0 % vs. 105.0 %) and cost ($ 916/t vs. $ 2,798/t). The obtained data are explained by the fact that a complex of components was used, some of which are production waste, with reasonable moisture and lipid content, which improved the technological characteristics of the extrudate. An applied aspect of using this scientific result is the possibility of rationalizing the extrusion process of oilseed meal to achieve the desired texture, porosity and stability of the lipid component of the product

Published: September 2023

This paper considers the influence of higher harmonics in dynamic action systems due to their complex movement in the process of interaction with the technological load. The object of research is the process of propagation of oscillations in complex dynamic systems. One of the problems in the application of oscillatory processes is the consideration of higher harmonics in the overall movement of systems. To solve the problem, the idea of using a hybrid model that takes into account both discrete and distributed parameters was proposed. The resulting mathematical discrete model in the analytical equations of motion of the dynamic system preserves continuous properties in the form of wave coefficients. These coefficients in their analytical form take into account the contribution of higher harmonics of both the reactive (elastic-inertial) and active (dissipative) components of the resistance force. The studies were carried out on a model of a plant with a multimode spectrum of oscillations and a nonlinear dynamic system, which is a system with piecewise linear characteristics.A series of experimental studies with a wide variation of the change in the frequency of oscillations was carried out on the installation with a multimode spectrum of oscillations. Zones of manifestation of higher harmonics along the vertical axis of force action were revealed. The given spectrum at the exciter frequency of 35 Hz showed the manifestation of the spectrum component (around 70 Hz) along the X axis, which is an important result for practical application. For a system with piecewise linear characteristics, the manifestation of multimode, which manifests itself in the form of subharmonic and superharmonic oscillations, was determined. The contribution of each harmonic is determined by applying the obtained dependences. The results were used in the development of algorithms and calculation methods of a new class of dynamic action systems taking into account the contribution of higher harmonics

The object of research is the processes of occurrence, perception, and redistribution of loads in the supporting structure of a gondola car with unloading hoppers. In order to increase the carrying capacity of the gondola car, and accordingly the profitability of railroad transportation, it has been proposed to improve its structure. This improvement implies the installation of unloading hoppers in its middle part. According to preliminary calculations, the use of unloading hoppers could increase the usable volume of the body by 2.82 m3. At the same time, the carrying capacity of the car would increase by 3.8 tons. Accordingly, the axial load on the wheelsets would increase. It is possible to solve this issue by using wheelsets with increased axial load in bogies.
As part of the research, a mathematical modeling of the vertical dynamics of the gondola car during its movement in the empty and loaded states of the rail track was carried out. It was established that the movement of the car is evaluated as "excellent". The calculation of the strength of the gondola car body under the main operational load modes was carried out. The stability of the car's equilibrium was determined, and its modal analysis was also carried out.
The peculiarity of the results within the framework of the study is that the proposed improvement could be implemented not only when designing a new car structure but also during modernization.
The area of practical application of the results is the machine-building industry, in particular, railroad transport. The conditions for the practical application of the research results are compliance with the axial load within the permissible values.
The research reported here will contribute to improving the technical and economic indicators of cars, as well as increasing the profitability of railroad transportation

In order to study the patterns of deformation and change of concrete structures, studies of the fiber Bragg lattice in the form of a measuring sensor were carried out. Fiber optic sensors have several advantages: small size, resistance to electromagnetic interference, high sensitivity, wide range, simple structure, high reaction rate, corrosion resistance, geometrically versatile and resistant to external influences.
This work is related to the development of the characteristics and behavior of strain sensors acting on a fiber Bragg lattice using computer modeling. The work focuses on the analysis of the operational characteristics and behavior of strain sensors acting on the fiber Bragg lattice. The sensor is used to measure the deformation of an object whose resistance varies depending on the applied force. This is shown by an example of how a fiber Bragg lattice can demonstrate strain sensors. In the work, a simulation was carried out using a computer program to simulate the operation of a fiber Bragg lattice deformation sensor.
When measuring the deformation, calculations with the Young's modulus formulas were used for a more accurate calculation of the data. When measured, the wavelength left from 1662 nm to 1666 nm, as well as a constant temperature from 20 °C to 40 °C. The results show the following, the values of the Young's modulus are 23.25 Pa, the Poisson's ratio is 0.167 br, the modulus of elasticity at shear is 9.96444 Pa. And in this regard, the results of this work show: the first is that changes in the magnitude, position and shape of the deformation can reflect the dynamic evolutionary process of deformation during bending on the structure. The following is the deformation curve has a good corresponding relationship with the change in the applied pressure, which shows software modeling in different types of deformation.
The conclusion shows that the technology of monitoring fiber-Bragg lattice sensors has a good effect on internal deformation and control of mechanical stresses during model tests; it provides new methods and monitoring tools for model tests

The issues of creating a method for solving a multi-criteria task of the importance and risk (hazard) assessment of trunk pipeline objects (sections) are considered. The method is developed on the basis of the analytic hierarchy process. Each object (section) of trunk pipelines is characterized by a set of particular criteria that have their own scale of possible values of different physical nature and different dominance in determining the overall object importance. In this regard, there is a problem of transition from estimates by physical parameters to dimensionless assessment using some membership function. The study proposes an approach to automating the process of assessing objects by particular parameters in the analytic hierarchy process. For this purpose, a method is proposed that allows experts to be excluded from the process of filling in the paired comparison matrix based on the formation of a system of rules. Having a vector of criteria importance and guided by a system of rules, it is enough to specify the actual values of criteria for each alternative to compare objects. Based on this method, a model has been developed that allowed experimental studies to be carried out in the developed software. This method, as well as the developed importance assessment and decision-making software, is used in the automated system of electrochemical protection of main pipelines. The results of evaluating the importance of criteria for the task of risk assessment of gas pipeline sections are presented. The results obtained and their practical implementation in the management of main gas pipelines confirmed the effectiveness of the developed method. This allows you to make decisions in situations where it is necessary to carry out a multi-criteria selection of currently effective solutions and management strategies, assess risks, prioritize elements and coordinate actions for modernization or development

The object of research is histograms of the dynamics of dangerous parameters of the gas environment, the values of which are measured in real time at the intervals of absence and ignition of materials. The method of determining histograms during a typical selection of measurements is described. This method allows one to determine histograms for samples of an arbitrary position and the size of the data interval of measurements of the dynamics of dangerous parameters of the gas environment. On the basis of histograms on the intervals of the absence and occurrence of fires of test materials, indicators of their summary statistics can be determined. Laboratory experiments were conducted to study the features of the histograms of carbon monoxide concentration, smoke density, and temperature of the gas medium for intervals of reliable absence and appearance of ignition of materials in the form of alcohol and textiles. The results of the analysis of the histograms clearly show that the dynamics of the studied dangerous parameters at the indicated intervals differ from the Gaussian. At the same time, the histograms differ in shape, which depends on the type of ignition material and the corresponding dangerous parameter. Based on the features of the histograms of the dynamics of dangerous parameters on the intervals of the absence and appearance of fires of test materials, the simplest indicators of summary statistics in the form of the range, number, and position of the modes are determined. It was established that when alcohol ignites, the variation range of carbon monoxide concentration, smoke density, and gas temperature increases from 0.545, 0.068, and 0.161 to 7.121, 0.523, and 8.71, respectively. At the same time, the range of variation of these parameters during textile ignition increases from 0.182, 0.205, and 0.323 to 0.394, 0.386, and 2.903, respectively. The obtained results in aggregate or one by one can be used in practice for early detection of fires in order to prevent the occurrence of fires in premises

Published: September 2023

The object of the study is the system of training aviation specialists. The problem solved in the research is to increase the efficiency of decision making in the tasks of professional training of pilots while ensuring a given reliability, regardless of the hierarchy of the system of evaluation indicators. The subject of the research is the process of assessing the qualities of civil aviation pilots using fuzzy cognitive maps. The hypothesis of the research is to increase the number of indicators for assessing the quality of training of civil aviation pilots, with restrictions on the efficiency and reliability of decision making. The list of factors that influence the professional training of aviation personnel involved in ensuring flight safety is given.
A mathematical model of professional training of aviation personnel involved in ensuring flight safety has been developed. This mathematical model differs from the previously known results:
− the possibility of forming a generalized indicator of assessment and selection of decisions on the basis of changing sets of partial indicators, taking into account the complex multi-level structure of assessment of aviation personnel;
− the ability to aggregate heterogeneous indicators (both quantitative and qualitative) to assess and select solutions that differ in measurement scales and value ranges;
− taking into account compatibility and different values of partial indicators in the generalized assessment of decisions;
− flexible adjustment (adaptation) of evaluation models when adding (removing) indicators and changing their parameters (compatibility and significance of indicators).
According to the results of the analysis of the effectiveness of the proposed model, it can be seen that the proposed assessment model takes into account 30 % more assessment indicators than standardized ones
