Authors: Hamid Abd Rahman
Published: November 2022

PurposeThis study explored the three roles of Makassar in advancing the archipelago's spice routes: port growth arrangement, maritime policy, and maritime trade management in the XVI—XVII centuries.MethodThis study used historical research methods including heuristics, source criticism, interpretation, and historiography. The sources of data used were local sources (lontara) and foreign sources (Portuguese, Dutch, and English) to answer the three problems mentioned above by placing Makassar as the subject of the Nusantara spice route.Results/FindingsThe results of the study are: 1) the port growth arrangement the Makassar authorities did was by responding to the global trade dynamics around the spice route, such as focusing on structuring its ports as the centre of the Maluku spice trade. Second, maritime policy was implemented through free ports and the principle of Mare Liberum to advance Makassar to become an entrepot and a cosmopolitan world city. Third, the codification of Ammana Gappa's shipping and trade laws in Makassar further strengthens the maritime identity of the Makassarese, Bugis, and Mandar people in building the spice route of the Archipelago.ConclusionStarting from the perspective of the archipelago as a subject, this study shows the role of Makassar in promoting the spice route. Studies like this can also be developed at other ports on the spice route, thereby strengthening the archipelago's contribution to the history of the world's spice routes.

PurposeThis study examines the politeness strategies employed by male and female students and its differences across genders. MethodTo collect data for this qualitative study, 16 participants (with equally eight male and female students) were purposefully opted from the Department of English Language Education at UIN Ar-Raniry Banda Aceh. Eleven situations created to obtain responses from students using a semi-structured interview. The framework of analysis is based on Brown and Levinson’s politeness strategy. Results/FindingsThe study found that male and female students use four politeness strategies. They are (a) bald on record; (b) positive politeness; (c) negative politeness; and (d) off-record. The results indicated that positive politeness is the most prevalent strategy, while bald on record is the least utilized strategy. The politeness strategy was utilized when the participants wanted to express their view to classmates or lecturers. The students performed the strategy because they wanted to support their beliefs or statements unswervingly. Male students used more positive politeness and expresses ideas more directly than female students. ConclusionThe study concluded that both male and female students at the Department of English Language Education, UIN Ar-Raniry Banda Aceh exercised all varieties of politeness strategies. The most applied approaches were positive politeness strategy, followed by the negative politeness strategy, off-record and eventually bald on record as the least frequent politeness strategy.

Insurance Premium Formulation for Agricultural Commodity Prices
Authors: Wendra Betri
Published: November 2022

This research develops the appropriate formula to determine insurance premiums on agricultural commodity prices that provide coverage to policyholders for losses caused by falling prices. The price component is assumed to follow the Brownian Geometric motion in determining the insurance premiums for agricultural commodity prices. So, through the Ito process, a target price can be selected and is used as a reference to determine whether a claim can be made or not at harvest time. The approach of the Black-Scholes model is used to construct an appropriate model to determine insurance premiums of agricultural commodity prices due to a decrease in prices from the expected price. A simulation study is carried out using daily price data for red chili commodities in the Jambi province in 2020 with several assumptions made based on literature studies and farmers’ common habits in Jambi. The simulation results indicate that the average return is -0.001069649, and the standard deviation is 0.07297269. Thus, the expected estimated value of the profit rate is -0.001069649, and the estimated volatility value is 0.07297269. Furthermore, using the target price value, the red chili price insurance premium for a one-planting period with an area of one hectare is Rp. 1,527,088.Keywords: agriculture insurance; Black-Scholes model; European option; Ito process. AbstrakPenelitian ini mengembangkan formula yang sesuai untuk menetapkan harga premi asuransi harga komoditas hasil pertanian yang memberikan pertanggungan kepada nasabah atas kerugian yang disebabkan oleh turunnya harga.

Diabetic foot ulcers (DFUs) present as a debilitating complication of diabetes which approximately affects 6.3% of the global population with significant mortality and morbidity consequences. While one-third of the total cost of diabetic care goes to DFU treatment, 20% patients have unresolved ulcers, while 40% experience recurrency within one year. To improve outcomes in DFU care, activated autologous platelet-rich plasma (aaPRP) is one of the adjuvant therapies proposed. Containing various bioactive proteins such as growth factors and cytokines, it possesses regenerative, antioxidative, anti-inflammatory, and antimicrobial qualities. Furthermore, its autologous nature, which also makes it a highly safe treatment modality, is also promising. In this review, we shortly discuss the pathogenesis of DFUs and how aaPRP may tackle the key players in DFU pathogenesis to improve wound healing outcomes. We also briefly describe its method of isolation and the current views on aaPRP from an authoritative source. Lastly, we summarize the existing evidence for the utilization of aaPRP in the treatment of DFUs.

The objective of this retrospective study was to determine the complications of the first 30 tibial tuberosity advancement rapid (TTA-rapid) and 30 modified circular tibial tuberosity advancement (mcTTA) procedures performed by our team, and to compare the results with the findings reported in the literature. Our research was based on 30 procedures in each group. All dogs were client-owned. Data were collected only for the study of cases that had a minimum follow-up period of 3 months. Intraoperative (IO) and postoperative (PO) complications were assessed, with the latter divided into two subgroups: major and minor. Results obtained for the TTA-rapid group: IO complications 23.3% (7/30), major PO complications 13.3% (4/30), minor PO complications 16.7% (5/30). Results of the mcTTA group: IO complications 0% (0/30), major PO complications 3.3% (1/30), minor PO complications 20% (6/30). Comparing the complication rates, we found that there was a significant difference between the two groups in the occurrence of IO complications (P = 0.01054); however, there was no significant difference in the incidence of major (P = 0.3533) and minor (P > 0.9999) PO complications between groups. Our results are consistent with the findings reported in the literature and suggest that both techniques are efficient and carry a relatively low complication rate.
Attila's Invasion of Gaul in 451 and Re-horsing the Huns
Authors: Linn Jason
Published: November 2022

A debate has emerged on whether the fifth-century Huns evolved into foot soldiers or remained the same horse archers of the steppes as they had been in the fourth century. So far, the debate has focused on ecological and literary evidence. This paper approaches the argument from an angle neither side has considered: the distances Attila travelled. By examining how far the Huns covered on their longest raid and adducing comparative evidence of pre-modern armies on the march, this paper argues that Attila's Huns remained horse warriors.
Emberarcú mesterséges intelligencia
Authors: Kampis György
Published: November 2022

Összefoglalás. A jelen írás alapja a témában tartott előadásom.
Először általános kérdésekkel foglalkozom, majd a tervezett „EU AI Act”-ről lesz
szó, utána egy VW projektet ismertetek röviden, majd a „megmagyarázható MI”-ről
fogok beszélni, aztán egy saját, hazai kezdeményezésről, az Alfi projektről
teszek említést. Végezetül egy kitekintés zárja le az írást.

Summary. This writing is based on a lecture on the topic. In my
other (German) affiliation I am manager of a large-scale EU project called
“HumanE AI Net” (funded with 12m Euro) comprising 53 leading EU institutions,
including large universities (UCL London, LMU Munich, Sorbonne, Sussex or ELTE),
networks of research institutes (Fraunhofer, Max Planck Gesellschaft, INRIA, CNR
Italy), large international companies (ING Bank, SAP, Philips, Airbus), etc. In
the writing I discuss general issues related to Humane AI, the planned EU AI
Act, social credit systems, explainable AI, and the Alphie project,
respectively.

In April 2021, the European Commission proposed a regulation on artificial
intelligence, known as the AI Act. The regulation aims at
human-faced AI in a European dimension. Although it is still only a draft, the
stakes are high. The planned law has, however, faults (I maintain here), to be
corrected before the text passes as law.

Another subject to discuss is the study – and prohibition (at least in Europe) –
of social credit systems. The original “Social Credit System”
is a national credit rating and blacklist developed by the Government of the
People’s Republic of China. Proponents of the system claim that it helps
regulate social behaviour, improves citizens’ ‘trustworthiness’ (which includes
paying taxes and bills on time) and promotes the spread of traditional moral
values. Critics of the system, however, argue that it goes far beyond the rule
of law and violates the legitimate rights of people – in particular, the right
to reputation, privacy and personal dignity – and that it can be a tool for
extensive government surveillance and suppression of dissent.

“Explainable AI” (XAI) has become a hot topic in recent years.
AI applications are mostly “opaque”: this is especially true for learning
systems and by definition for neural networks (NN). The current fashion, “deep
learning”, usually means the application of a particularly opaque NN anyway. It
is natural not to know what the system is doing and why. So, let’s change that!
With this tenet, XAI was born. I review some solutions to the problem.

In the writing I also mention an application, Alphie, the first
version of which was done in the OTKA project “Good Mobile” and is now supported
by the MI National Laboratory. Alphie is a science-based playful application for
children that helps them to use digital tools more consciously and within
limits, while developing a variety of skills. It performs the functions of a
‘grandmother’ who shows emotions towards the child: can be e.g. angry, loving,
etc. The application makes the corresponding sounds (!) and facilitates real
social interactions (e.g. sends the child to play football (!).

Published: November 2022

This study aims to examine the impact of environmental costs dimensions on the financial performance of Iraqi industrial companies with the role of environmental disclosure as a mediator. The data was collected from annual reports of 25 selected companies of the Iraqi stock exchange and oil sector from 2014 to 2018. The results show that the average percentage of environmental disclosure in the industrial companies selected in this study was 20.0 % and the mean found was 20.2 %. The results also showed that environmental costs (contingent costs and external social costs) positively influence financial performance, while contingent costs, social costs, hidden costs, and Image & relationship costs show a positive influence on environmental disclosure. The findings revealed that environmental disclosure was positively significant in affecting financial performance. It was found that environmental disclosure fully mediated the relationship between environmental costs (hidden costs and Image & relationship costs) and financial performance. Environmental disclosure partially mediated the relationship between environmental costs (Contingent costs, and social costs) and financial performance. There is no mediation of environmental disclosure for the impact of Conventional costs on financial performance. It was also found that environmental disclosure mediated the impact of environmental costs (Conventional costs, Image & relationship costs, and External social costs) on financial performance. This indicates advantages for companies that produce less moderate environmental disclosure and enables them to gain investors’ confidence. This study's implications provide insights into the implementation of the measurement of environmental costs and environmental disclosure in Iraq.

Published: November 2022

This study considers the issue of assessing the time changes in forest plantations and constructing an algorithmic and software system for monitoring these changes. Modern systems that study vegetation changes do not have the necessary functionality and do not cover the range of observations discussed in this paper. Existing research methods are intended only to record changes that occur in forest ecosystems and take into consideration the peculiarities of a certain natural zone, which limits their use. At the same time, it should be understood that the requirements for modern systems should include additional components that could make the system universal and mobile. A comparative analysis of satellite images acquired from remote sensing by the Landsat 8 satellite system has been carried out to determine the areas affected by forest fires. During the classification, spectral analysis was used, and an index of fires was determined to indicate the burned areas. To analyze the changes that occur in forests due to fires, correlation-regression analysis is used. It has been proven that the area of sanitary felling after fires and the area of forest land traversed by fires demonstrated the greatest interconnection. The extrapolation and forecasting were carried out using a regression data model, the effectiveness of which is confirmed by a coefficient of determination of 0.87. The dependences built make it possible to conclude that by 2030 the number of forest fires will increase while the area of burned forests will not decrease. The developed mobile application could be popular among a significant group of users to monitor fire events. The practical result is the introduction of the built system, which makes it possible to quickly monitor forest plantations after fires and assess the areas that were affected.

The object of this study is the processes related to the emergence, perception, and redistribution of loads in the improved structure of a passenger car frame. The scientific and applied task tackled in this paper is to ensure the strength of the supporting structure of a passenger car under operating loads. In this regard, it is proposed to improve the frame of a passenger car by constructing a girder beam from two rectangular pipes filled with material with energy-absorbing properties. The regularities of the frame load have been determined by taking into consideration the proposed solutions. It was found that the maximum equivalent stresses in the frame, taking its improvement into account, are 11.2 % lower than in the structure without filler, and 11.7 % lower than in the typical design. The results reported here are explained by the fact that the use of rectangular pipes filled with energy-absorbing material contributes to an increase in the moment of resistance of the frame, and, accordingly, reduces stresses.
In addition, the study has determined the natural oscillation frequencies of the frame. The results of the calculation of the strength of the weld in the zone of interaction of the girder beam with the pivot beams are given.
A feature of the results obtained is that the improvement in the strength of the frame is achieved not by strengthening its components but reducing the load.
The scope of practical application of the reported results concerns railroad transportation, as well as other sectors of mechanical engineering. The conditions for the practical use of these findings are the introduction of closed profiles in the structure of vehicles at the stage of their design and modernization.
This study could help reduce the cost of maintaining passenger cars and improve the efficiency of their operation. In addition, the research might prove useful for designing modern railroad car structures
Devising a method for predicting a blood pressure level based on electrocardiogram and photoplethysmogram signals

Published: November 2022

Determining the level of blood pressure (BP) in a non-invasive way and without a sphygmomanometer cuff is of great relevance when conducting continuous monitoring or screening studies. In this regard, a method for predicting BP parameters based on the signals of the photoplethysmogram (PPG) and electrocardiogram (ECG) signals has been developed. It is proposed to use, as informative features, the time of pulse wave propagation (PTT) and a set of calculated pulse parameters of PPG. PTT is defined as the time intervals between the R-wave of the ECG and the corresponding characteristic points on the PPG acquired optically from the finger. As parameters of the PPG pulse, the known characteristics of this signal described in the literature are used, as well as additional informative features selected during the study.
In accordance with the above, the tools of machine learning theory were used to construct a classifier model and regression models. The approach described in this paper to determine BP makes it possible to use 10-second ECG signals in any of the 12 common leads and PPG signals from any optical type of sensor.
The built model of the classifier detects three levels of BP: low, normal, and high, at the accuracy metric=0.8494. The regression models predict systolic, diastolic, and mean BP parameters in accordance with the requirements of the British Hypertension Society (BHS) standard by the magnitude of the absolute error.
The proposed method for assessing the level of BP involves real-time measurements and can be used in the design of measuring equipment for screening studies, as well as in continuous monitoring tasks within the framework of BHS requirements.
Implementation of radar cross-sections model for targets with different scattering centers

Published: November 2022

Target scattering or reflection is used by radar systems to identify and detect targets. The larger the echo that was returned to the radar receiver, the superior the signal-to-noise ratio and the greater the likelihood of detection. The radar cross-section (RCS) determines the quantity of energy reflected from a target in radar systems. This work shows new modeling for radar targets with growing stages of fidelity. We introduce the RCS concept for straightforward point targets and extend this into additional complex states of targets with several scattering midpoints. In addition, we discuss the modeling of fluctuations in RCS with time and briefly consider the case of the polarized signal. Because the receiver and transmitter are co-located, the effort focuses on narrowband mono-static radar techniques. The RCS value changes between scans. We simulate the replicated power of a sent signal over 10,000 scanning over unit incident signals, assuming that the signal illuminates the target just once each dwell. The target is modeled by four scatterers that are placed at four square vertices. All scatterers are cylindrical-point targets on a 0.5-meter square XY plane without losing generality. The acquired results demonstrated how to generate target echoes while accounting for statistical fluctuations. From the relation between RCS and elevation angle variations for cylindrical targets, the obtained result demonstrated that the first two outputs are the same and confirmed that there is no reliance on azimuth angle. The comparison between wideband and narrowband RCS patterns demonstrated that the RCS profiles of the target-matched shallower nulls for azimuth direction are in the range of (40–50) degrees at zero elevation for 4 scatterers’ extended targets.

Published: November 2022

The production of non-alcoholic beer requires brewing wort with a low degree of digestion. That is possible with the use of non-traditional raw materials in production. The research object presented below is grain sorghum varieties Kazakhstan-16 and Kazakhstan-20. Nowadays, the production of non-alcoholic beer with technological methods is not studied enough. Therefore, plants with small capacities cannot produce it. This study justifies the use of grain sorghum to produce low-digestion wort. In addition, we justify that Kazakhstan-16 had the best indicators for producing non-alcoholic beer. The following ratio of malt for wort preparation to sorghum 60:40 and hydro module 1:6 are proposed. The prepared wort had an extractivity of 6.62 % and digestible carbohydrates of 25.89 % of the total. The ratio of digestible sugars to non-fermentable substances in the wort was 1:1.79, so 79 % constituted mainly non-fermentable sugars.
Mathematical experiment planning has been used to study the effect of malt and sorghum filling ratio and hydro module on the brewing wort's extractive matter yield.
Based on the results of this study, the brewing wort has a low digestion rate. However, the carbohydrate composition of the wort is due to the presence of mono- and disaccharides. This wort will produce a beer with an ethanol content of up to 0.5 % of alcohol and the organoleptic characteristics set.
High extractivity in the raw materials and their high gelling temperature account for these results. These factors made it possible to select a jumping mashing regime, which resulted in deep hydrolysis of the sugars into dextrins.
This study will allow using non-traditional grain raw materials and producing non-alcoholic beer in breweries of any capacity. These methods are cost-effective and do not require expensive equipment
Creation of automatic clamping mechanisms for spindle assemblies of machine tools using a formalized description of structural elements
Authors: Prydalnyi Borys
Published: November 2022

The characteristics of the functioning of automatic mechanisms for clamping workpieces and cylindrical tools in the spindle assemblies of metalworking machines determine the potential for improving the productivity and quality of processing. The conducted research is aimed at developing new approaches to the creation of automatic clamping mechanisms with qualitatively new and necessary characteristics of their functioning. The formation of new characteristics is achieved by implementing appropriate changes at the structural level of an object. The results obtained provide better opportunities for the development of structures of automatic clamping mechanisms by improving the systematization of a review of an increased number of alternative options for their structural elements. This was achieved by solving the problem of formal description and representation of structural elements operating on the basis of various physical effects within one subject area of the systematization matrix. The results allow strengthening the heuristic potential in the design and involving an extended range of physical effects suitable for effective energy transfer and conversion in the operating conditions of automatic clamping mechanisms. The possibility of describing structural elements as digital codes helps to increase the efficiency of analysis and processing of information of the initial design stages. Using the codes of the selected structural elements, three sequences corresponding to the structures of automatic clamping mechanisms according to the brief descriptions [1.7–2.4]–(1.1–2.3); [1.7–2.6]–(1.1–2.3); [1.7–2.6+1.6/1.7–2.1]–(1.1–2.3) were compiled. On their basis, designs of automatic clamping mechanisms with predictably better characteristics and extended technological capabilities are developed

Climate change and lower yields require maximum utilization of natural resources. In order to reduce the loss of valuable raw materials, it is relevant to substantiate craft innovative technologies involving local raw materials with maximum resource conservation. Taking into consideration global trends in the production of organic craft products, it has been established that there is a need to introduce resource-saving technologies.
The object of research for the preparation of craft confiture was quince and green tomatoes. We examined 5 samples of confiture with different ratios of quince puree to the green tomato puree. Sensory analysis revealed that compared to the score of the control sample (14.94 points), sample No. 3 (14.87 points) with a ratio of 2:1 quince puree to green tomato puree is rational.
It was found that the viscosity and shear stress indicators for control sample No. 1 and sample No. 3 are quite similar. The measurement results showed that the systems that were investigated have stable structure characteristics of viscous-plastic systems. The research results show that the introduction of green tomato puree into the composition of the model compositions has almost no effect on the viscosity of the masses (sample No. 3) compared to the control sample. The obtained data show that, regardless of the shear rate, the structure is actually the same.
It was established that in the prototype of confiture there are no significant changes in the chemical composition. However, there is a slight decrease in the content of carbohydrates, organic acids, and phenolic compounds, by 20 %, which is associated with a decrease in the quince content and the introduction of green tomatoes into the recipe. The energy value of the new product decreased by 5 %, which is insignificant. Microbiological studies indicate the hygienic safety of manufactured confitures from fruit and vegetable raw materials according to the specified indicators and fully comply with established standards

Published: November 2022

This paper considers the possibility of devising a technology of fast railroad communication for the transportation of containers between the port and customer enterprises in the course of intermodal transportation. The purpose of technology development is to reduce the share of the use of trucks on intermodal routes and thus solve a number of related environmental, transport, municipal, and economic problems. The devised technology is based on the principles of bringing the railroad as close as possible to the end points of the route, minimizing the number of intermediate modes of transport, and enabling the maximum speed of movement of containers by rail. For this purpose, the use of MetroCargo™ freight terminals and CargoSprinter modular trains is proposed. In the course of the study, the task to reliably plan the operation of the fleet of such trains for the delivery of containers between the port and enterprises under the conditions of "noisy" initial data was set and solved. To this end, the problem was formalized in the form of a model of mixed programming, based on the principles of robust optimization. To optimize the model taking into consideration the principles of robustness, a procedure was proposed that uses a two-circuit genetic algorithm. As a result of the simulation, it was found that the resulting plan was only 6.5 % inferior to the objective criterion of the plan, which was compiled without taking into consideration robustness. It was proved that the devised model makes it possible to build an operational plan for the delivery of containers by rail, which is close to optimal. At the same time, the plan is implemented even in the case of the most unfavorable set of circumstances in the form of delays, shifts in the time windows of the cargo fronts, etc., that is, under the actual conditions of the transport process

The problem that is solved in the study is to increase the efficiency of decision-making regarding the state of the control object while ensuring a given reliability, regardless of the object's hierarchy. The object of the study is decision support systems. The subject of the study is the process of assessment and parametric control of the state of the control object using the firefly algorithm. The hypothesis of the study is an increase in the efficiency of assessing the state of the control object with a given reliability. In the course of the study, an improved method of parametric control of the control object based on the improved firefly algorithm was proposed. General provisions of artificial intelligence theory were used for solving the problem of object state analysis and subsequent parametric control in intelligent decision support systems.
The essence of improvement is to use the following procedures:
− taking into account the type of uncertainty about the state of the control object (complete uncertainty, partial uncertainty and complete awareness);
− taking into account the noise of data on the state of the control object. Data noise refers to the degree of information distortion created by the enemy's electronic and cyber warfare;

The basic principles of the need to develop a methodology for determining the level of protection of the rescuer's head during search and rescue operations in mountainous areas under conditions of low temperatures have been substantiated in this paper. The shortcomings of the existing system for ensuring the safe mode of search and rescue operations of rescuers in mountainous areas at low temperatures have been identified. Based on the statistical analysis of search and rescue operations, it was established that the greatest number of them occurs in the fall-winter period. It was determined that on the territory of the Carpathian Mountains the largest number of search and rescue operations is carried out in Zakarpattia, Ivano-Frankivsk, and Lviv oblasts. An analysis of working conditions was carried out. The results of studies into the effectiveness of thermal insulation of protective clothing of a mountain rescuer were analyzed. Mathematical modeling of heat and mass transfer in the body of a mountain rescuer was carried out using MATLAB software. Modeling of changes in temperature processes in the volume of the rescue head model was carried out under the influence of environmental temperatures: –10 °C, –20 °C, –30 °C, and a metabolic rate of 600 W/m2. Modeling was carried out on a 4-layer segment of the head. It was established that the effect of low temperatures on the face, head and, accordingly, the hypothalamus through the frontal part of the rescuer's skull leads to disability already at minute 17 in the absence of head protection equipment.  The use of a model for predicting a decrease in body temperature as a result of exposure to the external environment and the level of protection by the rescuer's individual means will determine the time of risky decrease in brain temperature (up to +32 °C) and prevent a negative impact on the health of the rescuer

In this study, a systematic analysis of the global trends of the studies carried out between 1988‒2021 on integrated reporting, which is a non-financial reporting tool that focuses on the process evolving from the shareholder approach to the stakeholder approach and the concept of value creation, which is jointly focused on corporate governance and reporting and visualization is performed. It is thought that bibliometric analysis of academic studies in the field of integrated reporting will make important contributions in terms of revealing which concepts are discussed in the literature and which relationship dimension. For this purpose, the data obtained from the Web of Science Core Collection Database were analyzed with the VOSviewer software. In the database, 462 studies were reached in the date range determined by the keyword “integrated reporting” in the title category. A systematic bibliometric analysis was conducted that included different variables such as citation counts, leading authors, organizations, keywords, and countries where the articles were written. According to the findings from the analysis, the three most influential journals for integrated reporting research are Meditari Accountancy Research, Journal of Intellectual Capital, and Sustainability. The vast majority of studies were published in the English language. The three most published authors are Raimo Nicola, Vitolla Filippo and Dumay John. The most influential institutions are Bucharest University of Economic Studies, Lum Jean Monnet University and Macquarie University. The findings will help researchers in the field understand the overall trend, relevance and performance of variables in globally integrated reporting research, and will provide guidelines for further research
Improvement of methods for description of a three-bunker collection conveyor
Authors: Pihnastyi Oleh , Chernіavska Svіtlana
Published: November 2022

The object of current research is a multi-section transport conveyor. The actual control problem of the flow parameters of a multi-section conveyor-type transport system with a given control quality criterion is solved. Algorithms for optimal control of the flow of material coming from the input accumulating bunkers into the collection section of the conveyor, ensuring the filling of the accumulating tank in the minimum time were synthesized. An admissible control of the material flow from the accumulating bunkers is found, which allow filling the accumulating tank, taking into account the given distribution of the material along the section of the collection conveyor at the initial and final moments of the filling time with minimal energy consumption. The synthesis of algorithms for optimal control of the material flow from accumulating bunkers became possible due to the determination of differential constraints in the optimal control problem based on an analytical distributed model of a transport conveyor section. The distinctive features of the results obtained are that the allowable controls contain restrictions on the maximum allowable load of material on the conveyor belt and take into account the initial and final distribution of material along the collection conveyor section. Also, a feature of the obtained results is the consideration of variable transport delay in the transport conveyor control model. The application area of the results is the mining industry. The developed models make it possible to synthesize algorithms for optimal control of the flow parameters of the transport system for a mining enterprise, taking into account the transport delay in the incoming of material at the output of the conveyor section. The condition for the practical use of the results obtained is the presence of measuring sensors in the sections of the transport conveyor that determine the belt speed and the amount of material in the accumulating bunkers.

This paper considers the organizational and legal support of the processes of digitalization of innovation in the financial and tax sectors. The main prerequisites were identified, and the role of financial and tax innovations in the development of the economy at the macro level was defined. Emphasis is on digital technologies as the main driving force of innovation in the financial and tax sector. The relationship between the concepts of "financial and tax innovations" and "financial engineering" has been established. The main directions of digitalization of the financial and tax sectors are identified. The digital technologies that have the greatest impact on financial and tax innovation are identified, namely: blockchain, Big Data, artificial intelligence, cloud technologies, the Internet of Things. The directions of legal regulation were substantiated and further steps to develop legal support for the digitalization of the financial sector were determined. To this end, the components of legal regulation, institutional regulation, and scientific and methodological regulation of digitalization of the financial sector are detailed. In contrast to numerous studies in the field of legal support and regulation of digitalization of the financial and tax sectors, it has been hypothesized and proved that the greatest effect is achieved with the harmonious interaction of institutional components. The system of management of financial and tax innovations in the context of digitalization has been improved. To this end, the stages of the transformation process of the financial and tax innovation management system in the context of digitalization were detailed and an algorithm for digitalization of the financial sector has been developed. The scope of practical application of the research results is the development of the financial and tax sector through the introduction of digital tools
Development of information support for simulation of the process of deformation of root polymer plate in book blocks sewed with threads

Published: November 2022

The object of this study is the processes of deformation of the root polymer plate reinforced with stitches of threads with preliminary tension in book blocks sewn with threads. The analytical and experimental studies reported here are based on the application of the methodology for developing a simulation model of the process of deforming the adhesive polymer plate. The basic assumption of the study is that the use of information support for simulation modeling will contribute to the improvement of the structural and technological parameters of the root part of the book blocks sewn with threads. This cannot be achieved without analyzing and decomposition of the technical system of the book block, classifying subsystems and describing them in the form of a finite set of classes and the connections between them. A procedure for determining the mechanism of interaction of elements of the root part of book blocks sewn with threads is proposed. It is shown that the residual cyclic deformation of the adhesive plate and the stitches of the implanted threads depends on the strength of the bonds between the elements of the joined structure of the materials. It also depends on the number of cycles of discrete loads heterogeneous in terms of dimensional indicators and the place of their application. This is due to the fact that stitches of threads are only partially implanted into the structure of the adhesive plate, the other part that fastens the folds of notebooks is outside the adhesive plate. The influence of cyclic loads applied at different angles relative to the stitches of the threads was revealed. The angular discrepancy fluctuates, in the case of using PVAD D51C glue, in the range of 0.735–0.907, and, for Technomelt GE3636 thermal glue, 0.913–0.940. The developed simulation model of the processes of deformation of the root polymer plate makes it possible to determine the mechanism of interaction of the elements of the root part of the book blocks and predict the durability of the product
