THE PROCESS OF DETECTING BLOCKS WITH REPETITIONS AND EXCESS BUILDING USING A LANGUAGE-INDEPENDENT INCREASE DETECTOR

To avoid malfunctions of the developed software caused by errors, even when developed by professionals, a number of automated tools are used, which allow to evaluate the software code. A variety of detectors are commonly used to detect errors that occur due to duplicate blocks of executable code. The importance of developing such detectors is that the product is not dependent on the programming language and has a simple algorithm for finding cloned blocks of code. The approach of the language-independent repetition detector is based on a method based on the use of the clone index. It is a global data structure that resembles a typical inverted index. This approach is based on the text, ie the method becomes the basis for research independent of language. In recent years, additional methods have become increasingly popular, which analyze the source and executable code at a smaller level, and there are attempts to avoid unnecessary recalculations, by transferring information between versions. Reviewing the research presented in the works of scientists dealing with this problem, it was decided to propose an approach to improve methods for detecting repetitions and redundancy of program code based on language-independent incremental repetition detector (MNIDP). Most additional research is based on tree-like and graphical methods, ie they are strictly dependent on the programming language. The solution in the MNIDP campaign is to take the text as a basis, ie the method becomes the basis for research independent of language. This technique is not strictly language-independent, but due to the fact that the tokenization stage will be included, with the help of minor adjustments the desired result has been achieved. This provides a detailed analysis of the internal composition (namely, elements) of the detector and explanations of the work at different stages of the detection process.

MODELLING OF TEMPERATURE FIELD DISTRIBUTION IN BIOLOGICAL TISSUE THERMAL LESION

Early determination of the thermal lesion degree in case of scald accelerates the treatment process and increases its effectiveness. The thermal lesion degree can be evaluated by determining the temperature difference between healthy and injured areas of biological tissue. For this purpose, a model of biological tissue in the form of a multilayer structure can be used. Heat exchange processes in such a structure are described by a generalized thermal model. Such structure contains conditionally flat heat sources located in each layer, which have the form of a developed network of blood vessels. The considered model of biological tissue quite accurately describes the heat exchange processes in body tissues. The article considers heat exchange processes that take place in biological tissue and a number of assumptions that should be used to mathematically describe these processes were identified. During the analysis of heat transfer process, the equations of temperature distribution in the tissue layers and the boundary conditions that describe the thermal interaction of the model with the environment are determined. As a result, the model of the stationary thermal regime of a biological tissue fragment in the form of a generalized thermal model and a mathematical model of the temperature field distribution in this fragment is obtained. This model is determined by many parameters, which are divided into 3 groups: thermophysical parameters; structural and topological parameters; parameters of the blood vascular system. Models of the particular fragment thermal regime are unequivocally determined by a combination of these parameters. For the analysis of temperature in any point of biological tissue modelled part mathematical model of temperature field distribution in stationary mode was developed. This model allows reasonable approach to the thermal lesion degree evaluation on the basis of the surface temperature difference between healthy and injured areas of tissue.

DYNAMIC LOAD REDUCTION DEVICE IN MACHINE DRIVE WITH SPRING AND SELECTION OF ITS PARAMETERS

The peculiarity of the technological equipment of light industry is the significant dynamic loads that occur during unstable operating modes and is one of the main reasons for reducing the reliability and durability of its operation. The problem of increasing the reliability and durability of their work by reducing the dynamic loads is relevant, because the known means of reducing the dynamic loads in the drive of machines can not always be used in light industry machines. Therefore, when designing light industry equipment, first of all, attention should be paid to reducing the dynamic loads in the drive and preventing accidents. The paper considers the feasibility of using a device with a torsion spring to reduce the dynamic loads in the drive of process equipment, check its performance and develop a method for selecting rational parameters. In the course of work modern methods of researches of mechanical systems are used for the purpose of an estimation of expediency of use of the device with a torsion spring for reduction of starting dynamic loadings in the drive of machine. On the basis of the analysis of features of work of the technological equipment of light industry the expediency of use in the drive of cars of the gear safety coupling with a torsion spring is established. A new design of the device is proposed to reduce the dynamic loads that occur during machine start-up. Unlike the known devices, the proposed device is made in the form of a toothed safety clutch with a torsion spring, which simplifies its design and increases efficiency. The use of a cylindrical torsion spring as an elastic element, which connects the half-clutch to the flange on which the satellite gears are mounted, prevents overloading of the drive and the choice of rational rigidity of the device depending on the change of operation, which increases its durability and expands performance. The method of checking the efficiency of the device for reducing dynamic loads and selecting its rational parameters is presented. The scientific novelty is the development of scientific bases and engineering methods of designing devices to reduce dynamic loads in the drive of technological equipment. The practical significance lies in the development of a new design of the device to reduce the dynamic loads in the drive of machines and the engineering method of choosing its rational parameters.

These systems are used to determine the equipment performance for transporting a variety of materials. In particular, they are used to control the movement of bulk materials mixtures components. For such technological processes, it is fundamentally important to ensure constant flows intensity. The paper identifies three variants of sensor connection schemes, analyzes their advantages and disadvantages. It is established that the structure “one ADC – several sensors” allows to reduce equipment costs and at the same time to provide the minimum parameters influence of a transmission line on a useful sensor signal. The “one-to-one” scheme provides the connection of each sensor to its own ADC. “Circuit with multiplexer” allows to increase the number of sensors connected to one ADC. It is established that the best option in terms of reducing the interference effects on the analog signal and the cost of creating a system is the scheme “one ADC – several sensors”. The algorithm of information transfer from ADC to microcontroller (MC) is analysed. It is calculated that HX711 ADC chips provide the maximum data rate of 18.5 values/s. It is proposed to transfer data between the MC and the server using the TCP protocol because it avoids data loss and provides the necessary data transfer speed. The structure and formats of data that are transmitted from the mass sensor to the ADC, microcontroller, web server and database are proposed. The main speed, design parameters, advantages and disadvantages of wired and wireless data network between MK and the server are determined. Recommendations for the design of such a network depending on the characteristics of the premises in which the data collection system will be used have been developed.

TECHNOLOGY OF GEORGIAN CUISINE FLOUR PRODUCTS USING AGGLUTEN FLOUR

The article highlights the relevance of the development of flour products of Georgian cuisine using gluten-free flour. The technology of gluten – free khachapuri with cheese with the use of gluten – free types of flour – corn, rice and structurants – corn starch and a complex of polysaccharides of flax is substantiated. Traditional khachapuri technology involves the use of wheat flour, which cannot be used in the production of gluten products due to the presence of gluten in gluten proteins. However, according to previous research, other types of gluten-free flour can be effectively used in the production of gluten-free products – corn, rice in combination with effective structuring agents – starch, non-starch polysaccharides. In this regard, we proposed in the production of yeast dough for khachapuri to use a flour mixture of corn and rice flour in combination with corn starch and flaxseed flour, which is characterized by a complex of polysaccharides – cellulose, insoluble polymers of phenolic slime, lime. The share of dietary fiber is up to 28% by weight of flax seeds or non-fat flaxseed flour. Dietary fiber helps to stimulate the intestines in constipation, play a positive role in reducing the risk of coronary heart disease, preventing bowel cancer, reducing obesity. Flaxseed mucus has a well-defined ability to swell, and therefore show high viscosity in aqueous solution or suspension. The hydrocolloid nature of the mucus has a beneficial effect on the water-binding and emulsifying properties of flaxseed flour. The developed products are characterized by high quality and competitiveness, they can be offered for health nutrition of various segments of the population, and nutrition of patients with gluten enteropathy. Due to the high content of dietary fiber, in particular valuable for the prevention of cardiovascular disease, obesity and colon cancer soluble fiber flax flour, it can be recommended for the health of people I work in toxic industries and live in environmentally polluted areas.

SOFTWARE CODE ANALYSIS SYSTEM FOR RISK ASSESSMENT AND QUALITY ASSURANCE OF SOFTWARE

The paper presents the results of research of various standards, rules and methods of writing software code and analysis of their impact on software quality and the likelihood of technical risks associated with information processes within the system. Most of the risks that arise while developing software products are due to errors in building the system architecture or writing code. As a solution for such problems, it is proposed to apply the developed set of rules and methods to build the system architecture and assess the quality of writing software objects. Metrics have been developed to estimate the size and complexity of the module by combining elements of Halsted and Chepin metrics. Also, a set of principles for optimizing the structure of the system, also known as SOLID principles, was presented. The application of these principles for system construction and analysis was substantiated in order to minimize risks, ensure the quality of the software system and provide opportunities for easy extensibility of the project. Using these methods will optimize the project both for use and for further development. The need for such optimization processes in terms of risk management is that the clearer the system and the easier it is to expand, the less likely it is that errors will occur in the future when adding new functionality.

METHOD OF DEVELOPMENT OF ISOEFFICIENT HETEROGENEOUS SYSTEM USING MACHINE LEARNING FOR THE PROBLEM OF DISCRETE TRANSFORMATION OF FOURIER

In this paper, the isoefficiency of MPP systems and heterogeneous CPU-GPU systems on the problem of discrete Fourier transform is considered. The development of parallel applications as its goal can not only reduce execution time, but also provide opportunities to solve problems of a larger dimension. The peculiarity of algorithm parallelization includes the efficient use of hardware while increasing the dimension of the problem is an important characteristic of parallel computing. However, currently heterogeneous systems have not been researched extensively to determine isoefficiency characteristics and build application-specific systems around said method, although there are articles that show potential using isoefficiency to design the system and using heterogeneous approach to accelerate performance of different tasks. Discrete Fourier Transform algorithm lets build systems that discretize analogue and digital signals and it can serve as a benchmark to test different systems. Algorithms suited for MPP systems can use analytical approach to find out issoefficiency function and to determine how scaling the system or changing the size of the task will change its performance metrics. One of the most popular approaches to linking up processing units in MPP systems is using hypercube topology. MPP system that is connected using this topology will be analyzed. CPU-GPU heterogeneous system will be analyzed using an approach based on polynomial regression. Due to the nature of heterogeneous systems, analytic approach used in MPP system is impossible. Predictive model based on polynomial regression will use modelling results from using CPU and GPU separately to estimate how much time it will take for heterogeneous system to finish the task. To ensure accuracy of the experiment, several systems will be used to model the task. Using this approach, resulting issoefficient heterogeneous system will be analyzed using performance metrics s

BLOCKCHAIN SYSTEM CONSENSUS ALGORITHMS

This article describes the main consensus algorithms, their positive and negative aspects. Consensus in the general sense means a way to come to an agreement. In the blockchain, which is a decentralized system that does not have a single governing body, various algorithms have been developed to achieve consensus. In a blockchain network, it does not matter whether the system participants trust each other or not. They must agree on certain principles of work that will apply to everyone. And this is a direct function of the consensus mechanism. Algorithms are described and an example of solving this problem is given, namely the problem of choosing a consensus for future systems. An example of using multiple consensuses in blockchain networks is given. Such consensuses as Proof of Work (PoW), proof of Capacity (PoC), proof of Authority (PoA), proof of activity (PoAA), proof of Importance (PoI), proof of Burn (PoB), proof of Stake (PoS) are described, as well as its subspecies: Leased Proof-of-Stake (LPoS), Delegated Proof-of-Stake (DPoS). Many different nuances about the mixed type of consensus are described and examples of such cryptocurrencies and systems are given. The subtleties of mining for each consensus are described. Examples of hash functions, masternodes, nodes, algorithms, as well as key features of certain cryptocurrencies with mixed consensus are given. It is concluded that the choice of consensus for building systems based on blockchain.

THE INVESTIGATION OF SORPTION CAPACITY OF SAPONITE GRANULATE IN RELATION TO HYDROCARBON MIXTURE IN THE DYNAMIC MODE

Their drawback can be explained by the high cost and regeneration complexity. That is why the usage of natural sorbents (Tashkiv saponite deposits, Khmelnitsky region). They are able to clean contaminated water from colloidal, molecular and ionic substances. Exploring the specified topic, physicochemical properties of various forms of saponites are studied; the area of their usage is defined. The paste for cleaning contaminated surfaces is developed on their basis. The research results have shown that the most effective method is to use natural saponite. The author of the article advises to conduct preliminary acid activation of clay minerals and modification of its surface multivalent metal salts. Saponite clay granulate is obtained with different time and sintering temperature. Granulation is shown to improve the strength and filtration characteristics of natural sorbents, increasing the filtration rate and the duration of the filter cycle. The influence of the granulation process on the sorption properties of the obtained granulated aluminasilicates is investigated. A detailed hydrocarbon analysis of the A-92 starting gasoline is carried out. The composition of the purified samples of the hydrocarbon mixture is evaluated with gas chromatography using saponite granulate (Octane rating = 94,013 according to the method of research) under static conditions. The structure changes of raw and acid activated saponite clay has been investigated by nitrogen adsorption method and scanning electron microscopy. Established that the porous structure of saponite clay mineral represented by micro-meso porous system with domination of micropores. Acid modification promotes the development of specific surface area (from 47,7 m2/g to 177,9 m2/g) and increase the total volume of pores (from 0,134 cm3/g to 0,201 cm3/g).
