A study on stability analysis was carried out in 30 diverse genotypes of ricebean (Vigna umbellata Thunb.) in eastern hill region of India. Significant differences among the genotypes over the years were observed for all the three traits studied. The first two principal components axis (IPCA1, 90.4% and IPCA2, 9.6%) could explain 100% of the total of the interaction variation. Correlation study showed that the stability parameters are highly associated with each other (p < 0.01). Multi trait stability index and genotype selection along with strength and weakness view of the genotypes to the traits inferred higher productivity of BSKB 28 (G29) for number of pods/plant and seed yield/plant and Ukhrul 15 (G17) for number of seeds/pod. Different stability measures selected seven genotypes, namely, Bete 6 (G22), IC002567 (G8), Ukhrul 6 (G13), Ukhrul 14 (G16), Ukhrul 15 (G17), Bete 4 (G21) and BSKB 3 (G28) as the most desirable and stable performing with good yield over the years.

The rise in atmospheric CO2 levels impacts humankind by threatening food and nutritional security. The strong correlation between crop yield and grain weight in cereals is an essential component of yield stability. Further, improving grain protein and mineral nutrient content is a crucial breeding target for cereal crops. The study was performed to understand the interactive effects of elevated CO2 (EC) and nitrogen (N) fertilization on grain ionome, grain yield parameters, grain morphology, and the expression of genes related to grain morphology. The changes in ionome and grain parameters were examined in response to two N levels optimal N (ON: 500 mg/pot) and high N (HN: 625 mg/pot) along with atmospheric CO2 enrichment [ambient (CO2) of 400 ±10 ppm and elevated (CO2) of 700 ±10 ppm]. Grain ionome (N, K, Ca and Fe) showed a general decrease in EC-grown wheat plants. The expression of genes related to grain length (TaGL3 and TaGL7) were upregulated, and those genes related to grain width (TaGW2 and TaGW6) were downregulated under EC in maturing spikelet of wheat. In the case of TaSnRK2, the expression was promoted by EC in HN treatment. The complex regulation of source and sink-associated gene transcript abundance indicates an EC mediated alteration in N and sugar signalling in wheat.

Published: February 2023

High density planting (HDP) has been used extensively to achieve high productivity in temperate maize and the same can be exploited in tropical/subtropical maize. Based on two years field evaluation of tropical maize inbred lines under different planting regimes, this study led to identification of high plant density stress tolerant (at 30 percent higher plant population than cultural practice) high yielding maize inbreds. Leaf angle of first leaf above ear, anthesis-silking interval, cob length, and 1000 kernel weight were found directly affecting grain yield under HDP. Specific cross combinations exhibiting higher grain yield under HDP (approx. 15-20 percent), than normal planting practices, were identified. This is the first report on systematic development and evaluation of parental lines under high plant population and to generate high plant density stress tolerant hybrids in tropical maize.

The present study involved estimating the combining ability effects and heterotic grouping to increase the efficacy of parental selection for successful hybrid development. A total of 52 F1 hybrids were generated by Line × Tester mating design by crossing 26 diverse maize inbred lines with two testers, namely, HKI 323 and HKI 1105. The 26 baby corn inbred lines were classified into a different heterotic group based on the specific combining ability (SCA) effects and heterotic groups specific and general combining ability (HSGCA). The SCA effects and HSGCA of baby corn yield without husk (BCY) classified the inbred lines into five and four groups, respectively. This is the first study of heterotic’s grouping for baby corn germplasm considering BCY based on SCA and HSGCA methods. The information generated through heterotic grouping may be used to derive new inbred lines and develop different heterotic combinations for further utilization in breeding programs.

Published: February 2023

In many methods for the production of natural leather, the process of liming-unhairing is carried out using toxic sodium sulfide, poorly soluble calcium hydroxide, etc., this increases the degree of pollution of wastewater, complicates the work of treatment facilities. To improve the ecological situation, some works suggest replacing the widespread sulfide-lime liming-unhairing with a two-stage pure lime one or by using sodium hydroxide with kaolin together. In the development of this direction, this paper considers the possibility of using another natural mineral, zeolite, known for its high sorption capacity, during liming-unhairing. The paper investigates the hypothesis of a delayed action of calcium hydroxide on raw hides with the addition of zeolite. The hypothesis provides for the following mechanism: the absorbing complex of the zeolite sorbs calcium hydroxide ions, and after a while the reverse process gradually takes place – the zeolite gives Ca2+ and OH– ions back into the solution. This is confirmed by the results of studying the sorption-desorption kinetics of calcium hydroxide by zeolite depending on the concentration of lime and mineral. The influence of liming-unhairing conditions (lime-sulfide and sulfide-free using calcium hydroxide, calcium chloride in the presence of zeolite) on the formation of the structure and properties of the semi-finished leather product (pelt) and finished leather (parchment) is considered. The expediency of sulfide-free lime liming-unhairing in the presence of zeolite has been established, which makes it possible to obtain a strong, filled leather with a reduced consumption (or even complete exclusion) of environmentally harmful chemical reagents.

We live in a time of rapid growth of information technology, which is firmly entrenched in our daily lives. It is simply impossible to imagine a modern person without social networks, because they perform a communicative and informational function, namely: communication, information retrieval, news exchange, etc. Five hundred million tweets are posted daily, making Twitter a major social media platform from which topical information on events can be extracted. So, there is a lot of information available to the user, which is difficult to identify something specific and necessary in the usual way viewing. Accordingly, there is a need for technologies that can quickly process large amounts of data and highlight only the information that is useful to a particular user. This technology called recommender systems. It automatically suggest items to users that might be interesting for them. Due to the desire to unite people with common interests, it is relevant to develop a recommendation system based on social networks that help in personification of the user and compilation of his psychotype using his profile. The paper has description and results of the creation of recommendation system. The basis of this work is one of the algorithms used in recommendation systems – the recommendation system is based on content filtering. It analyzes users’ Twitter posts and calculates their interests. If we consider all the words, our model will not have good results and do not pay attention to what is important to use. Therefore, the most important step is always filtering data, so the number one task is to speed up the time of filtering text and retrieving data from the social network for further processing. The feature of this system is that this algorithm uses parallel calculations and frequency analysis of the text.

It is known that manipulators with automatic and hand types of control are distinguished by the type of control system. In manipulators with an automatic type of control, the links of the executive mechanism are set in motion by servo drives operating according to a previously developed program. In manipulators with a hand control type, there is an operator who acts on the links of the control mechanism and drives the links of the executive mechanism. The paper presents the results of simulation the working of the manipulator with six degrees of freedom, performed in the software environment TIA PORTAL V.15.1. Namely, the first stage, creating technological objects used as digital doubles for starting stepper motors, which are installed in the design of the manipulator. The creation of technological objects will make it possible to check the correct operation of the manipulator in the test mode, to determine and program the necessary speeds and accelerations, to monitor and eliminate possible errors during start-up. To simplify the application of some technological functions that can be used together with the SIMATIC controller, the so-called Technology objects (TO) were used in the software environment TIA Portal. When using TO data, available functions are encapsulated and provided to the application developer for ease of access and convenient use in the application environment. In particular, in the area of «Motion control», such TOs are used to facilitate the control and processing of data from axes, additional motion control functions, as well as to support the developer in creating a specialized program with motion control functions. The first stage of simulation the working of the manipulator in the software environment TIA Portal was completed, namely the creation of technological objects of this manipulator, that is, the creation of digital doubles for three stepper motors of the type 28BYJ-48, which are used as drives for the task of moving the manipulator.

A physically healthy person has no problem putting on shoes or getting dressed daily. Meanwhile, the same issue for people with disabilities is often considerable discomfort or complete inability to perform this task independently. A survey, which allows us to obtain the most reliable information in the required amount, was conducted to determine the consumer’s priority requirements when choosing shoes for people with disabilities. This information was used to create the improved footwear design for this group of consumers. The development of comfortable footwear for people with disabilities should provide ergonomic and aesthetic features of the design, take into account the anatomical and morphological characteristics of the feet in the design, and be based on typical technological processes, without radical reorganization of production. The footwear for people with disabilities during prosthetics of the lower limb should provide easy penetration of the foot prosthesis into the shoe. That means that this footwear should be pretty spacious in design. There is also a problem with fastening clothes and shoes in the case of prosthetics of the upper limb. Therefore, the method of fastening special shoes should also be convenient and meet the needs of people with disabilities. A model of the footwear of the sports style was designed based on research and review of the modern market of orthopedic footwear, which will provide the comfort of the foot or prosthesis in the shoe by combining the use of structural elements such as a blind valve with a loop for fixing lacing, zipper and lacing.

The purpose of the research is adaptation of biclasticization criteria, which have the properties of external complement to the problems of classification of states of complex technical objects in the field of computer engineering. The principles of inductive modelling of complex systems, in particular, the principle of external complementarity, as well as the methodology of the theory of pattern recognition, methods of inductive cluster analysis, mathematical statistics are applied. The construction of the criterion of stability of intra-multiple distances is based on the schemes of known criteria of self-organization of models, in particular the criterion of model inconsistencies, which are widely used in multi-step image recognition algorithms with intelligent choice of optimal results. The paper proposes the application of the criterion of stability of intra-multiple distances in the problems of diagnosing the state of technical objects, in particular, in the field of computer engineering. Since the application of such a criterion requires the presence of a target feature, one of the options for splitting the original experimental database into two subsets has been adapted: a subset of target features and a subset of input parameters. The concept of intra-multiple distances is extended to the application of algorithms of optimal complexity in the criteria of self-organization algorithms. Intelligent algorithms for self-organization of models of optimal complexity can be used to increase the reliability of computer systems.

Published: February 2023

The article is devoted to issues of choosing a grinding wheel for processing various types of materials. Complications which arise when a tool does not meet the requirements of providing needed surface quality are analysed in this research. The problem of grinding surfaces with a heterogeneous structure is particularly highlighted paying special attention to composite coatings based on superhard compounds. Results of processing workpieces with titanium carbide-based coatings using grinding wheels with different hardness are presented. In order to prevent grinding defects generation and spoiling finished products, the special software subsystem is developed. It is designed to resolve the problem of tool selection automatically. This software is an advanced solution of the considered problem which is usually solved with the use of manuals and handbooks about different grinding wheel properties. As a part of the information system necessary databases are formed to enable software correct functioning. These databases contain information about different characteristics of grinding wheels and the surface material being processed such as kinds of abrasive, their hardness, thermal conductivity, mesh sizes, bonding as well as compound of the processed surface and its density, elasticity, crack resistance. Since required surface quality implies obtaining needed roughness, its value is also taken into account along with other properties. An interface of the developed program module is presented together with its operating algorithm. The suggested program is based on information, analysis, modelling, optimization modules and the module of monitoring grinding regime parameters. In the case that there is no data available for some kind of the surface material, a list of its structure categories can be additionally downloaded. This software allows to prevent from damaging workpieces in the process of their grinding. Therefore, the developed program provides recommendations about appropriate characteristics of the grinding wheel depending on the material of the processed surface and the conditions of the grinding operation.

Published: February 2023

To date, taking into account the strategies for the development of control systems and the active introduction of distributed generation sources into various spheres of the world economy, including those based on renewable sources of electrical energy, hybrid systems of artificial outdoor lighting controlled by intelligent control systems are being developed. The paper proposes an approach to the construction of an external lighting control system on city highways and public places. Regulation of external lighting is carried out by adjusting the luminous flux of lamps, and the sources of luminous flux are the lamps with which they are equipped. But not all types of lamps are suitable for adjusting the smooth change of light flux. If there is a communication channel between the network of lamps equipped with EIDs and the dispatching service, it is possible to transmit information about the state of operation of EIDs and the performance of lamps in order to detect deviations in the operation of EIDs and lamps that need to be replaced. In accordance with the given schedule for changing the level of external lighting, the KD software sends a command to change the level of light flux on specific lamps. The control unit transmits incoming information (a command) to the control unit, which, together with the lamp control channel connected to it, forms a local lighting control network. The decentralized outdoor lighting control system provides for the absence of a control room, server, server access devices, as well as the Internet as a means of communication, executive equipment of the substation and replacement of the PUS with the APUS, as well as the presence of service personnel who will service the equipment of the APUS substation, KOP and SC, as a result of the lack of feedback from the APUS to the OP, i.e. the maintenance of the PS is carried out directly by maintenance and programming specialists Thus, a scheme for decentralized management of outdoor lighting on city highways and public places was proposed.

The performed research of normative documents made it possible to quantify the technical conditions of anthropometric body measurements and to determine how the nomenclature of anthropometric measurements depends on the classification of clothing. The aim of the study was to develop a methodology for verifying anthropometric measurements of the human body, taking into account the functional characteristics of clothing. A criteria approach to the synchronization of verification means of standards identification of measurement names by measurement method and measurement classification groups (horizontal, vertical, others) was used. Validation of standard measurements for the ergonomic design of garments and harmonization of control measurement code designations in finished garments have been performed. Standard control measurements were interpreted into additional dynamic compliance measurements to take into account the level of deformation of parts during operation and to ensure freedom of movement. Technical regulation of the anthropometric information volume is confirmed by the equivalence of the optimization problems of the considered anthropometric standards in the form of the linear programming problem of the set of anthropometric measurements. The matrix of conditions for fixing anthropometric measurements in six regulatory documents was studied. It was established that the set pair 25 < 28 determines the technical conditions of quality control on the dummy of the finished product. Using basic and auxiliary reference measurements in the clothing size designation provides a flexible combination of chest, waist and hip measurements for women and chest and waist measurements for men. Consideration of the range of additional control vertical measurements is confirmed by calculating the indices of balance in the longitudinal direction of the female figure of size 164-96-104.
METHOD OF THE DECLARATIVE METAPROGRAMMING BASED ON DOMAIN-SPECIFIC PROGRAMMING LANGUAGES
Authors: STAVYTSKYI Pavlo , VOITKO Viktoriia ,   Vinnytsia National Technical University
Published: February 2023

A concept of declarative metaprogramming which focuses on program code generation is considered. The method is based on using domain-specific languages that are implemented by means of existing general-purpose programming languages. Since metaprogramming is based on using programs that produce other programs, the declarative approach means that the input and the output program code must be as close as possible in terms of syntax or ideally identical. In order to generate a program code, it is required to write templates that hold the exact structure of a resulting generated code but contain placeholders for specifics of concrete generated instances. Such an approach is highly useful when there is a need of generating a large number of similar program files by structure but different in details. The simplest way to define such templates would be just by constructing them from string literals by injecting the specific details using a string interpolation mechanism for example. However, such an approach does not provide type safety and compile time validation, so there is no guarantee the generated code is a correct and compilable program. The domain-specific language, on the other hand, replicates all the syntactic constructions of the target programming language so that, the resulting generated code would be the same as code written by the programmer. Moreover, having preserved all the syntax validations by the compiler on which the domain-specific language is based. The paper considers a concrete example of a code generator for a Starlark programming language, a dialect of Python while the domain specific-language is based on Kotlin language. Using the toolset of Kotlin, such a domain-specific language replicates such Starlark constructs as variable assignments, list comprehensions, library functions, slices, etc with a required level of customizability.

The article is devoted to solving the task of analyzing the essence, features, and rules of brand coloristic as a tool for influencing the target audience of a fashion brand. The authors proposed approaches to using mobile applications as color information technologies to develop brand coloristic of the projected image of a clothing model. As a result of the conducted research, a color design strategy for fashion brand garments was developed. The essence of a comprehensive study of color perception: its theory and practice, personalities, institutions, semantics, and the use of color information technologies for developing brand coloristic of the projected image of a clothing model is substantiated. The interaction of color in art, design, advertising, and science has been proven. Based on consumers’ physiological, emotional, intellectual, and behavioral reactions to color, a comprehensive system, “The meaning of color,” is proposed. The motives and behavioral mechanisms of consumers in the fashion industry have been studied, and the factors affecting the purchase decision have been determined. This made it possible to represent the information model of the reaction to the garment, as a component of the clothing color design strategy, by including subsets of stimuli and emotions in the design-projection process. The main rules of modern brand coloristic were analyzed and applied using modern color information technologies in the form of a ready-made Color Gear mobile application. The proposed process of using current color and information technologies to harmonize the graphic fashion image allows you to get an individual coordinated project image with a planned impression. Thus, it has been proven that the elements of brand color are an essential factor that affects the consumer’s perception of fashion brands and, as a result, sales and profits. Broad prospects for further development of the author’s mobile application for harmonizing clothing colors have been revealed, especially when it comes to finding a new color project image because the competition of fashion brands is active and demanding at the current stage.

This article presents the methodology and results of scientists conducted by the Department of Automation and Non-Destructive Testing Systems (ASNK) KPI. Igor Sikorsky and PJSC “RPA “Kyiv Automatic Plant”(KZA) experimental studies of the main components of the stabilizer of light armored vehicles (LAV). The purpose of experimental research is to measure on each of the motors of the stabilization system (SS) EDM20M, EDM02, EDM20 electromagnetic (τEL. MAGN.) And electromechanical time constants (τEL. MEX). Testing of engines according to the assessment of τEL. MAGN. were carried out as part of an automated instrument system for measuring mechanical quantities and stabilization and in an autonomous workplace for testing engines. When testing as part of the SS in the winding of the braked EDM20M (EDM02, EDM20) voltages were supplied from the amplifier of the engine control unit (ECU) level 27V. The feed time was limited to 20ms due to the use of technological time relay (TR) in the signal input circuit “SIGN. PWM “of the amplifier of the engine control unit. Simultaneously with the supply of this voltage, oscillography was performed: the voltage applied to the motor windings (to use this parameter as a reference) and the output voltage of the current sensor (UCS) of the ECU amplifier, which informs about the current in the winding. The current values were recalculated only for the maximum UCS values. The UCS oscillogram (increasing exponent) determined the time constant of the exponent, which corresponds to the electromagnetic time constant of the motor (excluding errors introduced by the inductances of the ECU chokes and power supply). When tested according to the autonomous scheme, the estimate τEL. MAGN. the engine was carried out according to the method, which is similar to the test method in the SS with the following differences: the voltage in the motor winding (hereinafter UPW) was applied at 2.4 V for ~ 25 ms; in the scheme of autonomous tests of engines the source of tension of a direct current B5-21, the switch 831140A 27B, technological R.Ch. to measure the EDM current consumed, a 75 mV × 50A shunt was installed in series in the motor winding. According to the results of experiments, the following main technical characteristics are established. Electromagnetic time constants are: 0.7 ms – for EDM20M; 0.7 ms – for EDM02; 0.85 ms – for EDM20. Electromechanical time constants are: 20 ms – for EDM20M; 24 ms – for EDM02; 26 ms – for EDM20.

The article examines the peculiarities of the construction of systems for diagnosing rotating electric machines in the real conditions of their operation. It is shown that in the specified modes of operation there is a problem of limited informativeness of input information parameters that can be used to build such systems. At the same time, an additional limiting factor that must be considered when designing and implementing such equipment is the limited possibility of intervention in the design of the electric machine, which is usually limited to the manufacturing plant. As a result of a thorough analysis of the latest research in the direction of the development of diagnostic systems for rotating electric machines, a systematization of the technological parameters of electric machines that are most suitable for use in diagnostic systems was carried out. It is shown that when choosing input parameters of diagnostic systems, it is advisable to consider their informativeness, selectivity, expressiveness and complexity of the acquisition algorithm. At the same time, it is substantiated that the choice of the optimal combination of diagnostic features cannot be considered from the point of view of superposition, since each of them will be characterized by the entropy of selectivity and severity relative to defects of different types. The expediency of choosing the type of input information of diagnostic systems based on the method of evolutionary search is shown. It is demonstrated that the mentioned method allows to more completely cover the search space than, for example, gradient optimization methods, and to obtain a solution close to the optimal one in a relatively short time (a small number of iterations). The concept and typical structural diagram of the system for diagnosing rotating electric machines based on a modified non-standard artificial neural network (ANN) and the structure of the ANN itself, which considers the current mode of operation of the electric machine during diagnosis and is characterized by high adaptability to the object of diagnosis, are proposed. An example of its hardware implementation is given.

The article is devoted to the development of intelligent monitoring systems of technological processes based on the use of machine vision systems. The principles of object-oriented formalization of the process of designing information technology of the classification of objects by the geometric shape of the image obtained from the machine vision system are proposed in the article. The proposed information technology is based on the use of machine learning technologies and provides for the selection of the best structure of the classifier model from a set of candidate models. Construction of candidate models is based on the use of the group method of data handling, based on the principles of self-organization of models. The outline of the image of the object obtained from the intelligent monitoring system is the input information. The set of input data contains a set of morphometric parameters that describe the geometric shape of the figure formed by the contour of the image of the object, as well as the label of the class to which the object belongs. The formation of the set of input data is implemented in the block «Image Processing». The decisive rule of classification is built in the block of synthesis of models of information technology of classification. GMDH neural networks were used as an algorithm for model synthesis. The choice of the best structure of the model is performed by a set of criteria. The information technology for constructing the classifier model is implemented by supplementing the block of algorithms for synthesis of MSUA models with the block «Class of models», which implements the process of selecting the class of functions for building models, and the block «Verification of models», which implements the best model structure. Construction of the meta-model of the design process was performed using a unified modeling language. The functional meta-model is represented by a use case diagram.
Organising Stakeholder Participation in Global Climate Governance: The Effects of Resource Dependency and Institutional Logics in the Green Climate Fund
Authors: Bertilsson Jonas
Published: February 2023

Public or stakeholder participation in environmental governance has been strongly advocated within the United Nations (UN) since the early 1990s. A relatively new mechanism for global climate finance that emphasises stakeholder engagement is the Green Climate Fund (GCF), a UN strategy for channelling funds from the Global North to the Global South. Drawing on previous critical approaches to multi-stakeholder involvement in global governance, this article explores stakeholder involvement within the GCF. The study combines ideas from institutional logics and resource dependency to provide a better understanding of how stakeholder arrangements are shaped in climate organisations. Results show that the GCF stakeholder arrangement favours private sector stakeholders – stakeholders that take a technical and apolitical approach to climate finance – and disfavours smaller, less resourceful stakeholders as well as those who perform a politicised watchdog function.
