Scalability and Performance of Microservices Architectures
Authors: Kerimovs Amirali
Published: November 2023

The inevitability of continuous evolution and seamless integration of dynamic alterations remains a paramount consideration in the realm of software engineering. This concern is particularly pronounced within the context of contemporary microservices architectures embedded in heterogeneous and decentralized systems composed of numerous interdependent components. A pivotal focal point within such a software design paradigm is to sustain optimal performance quality by ensuring harmonious collaboration among autonomous facets within an intricate framework. The challenge of microservices evolution has predominantly revolved around upholding the harmonization of diverse microservices versions during updates, all while curbing the computational overhead associated with such validation. This study leverages previous research outcomes and tackles the evolution predicament by introducing an innovative formal model, coupled with a fresh exposition of microservices RESTful APIs. The amalgamation of Formal Concept Analysis and the Liskov Substitution Principle plays a pivotal role in this proposed solution. A series of compatibility constraints is delineated and subjected to validation through a controlled experiment employing a representative microservices system. The suggested approach is poised to enhance the development of more sustainable microservices applications and elevate the efficacy of DevOps practices engaged in the creation and upkeep of microservices architectures.

Published: November 2023

Diptera have high capacity to adapt to anthropized environments and they present high medical and sanitary relevance, since they are related to pathogens transmission and myiasis causing. In this context, it is known that anthropic environments (e.g., street markets) with high human circulation and food supply can directly influence the composition and structure of muscoid dipterans assemblages. The aim of this work was to evaluate the effect of street markets on the composition and structure of assemblages of flies with sanitary importance in an urban environment of Toritama city, Pernambuco state, Brazil. The flies were captured using adhesive mousetrap “Cola Rato” before and after the occurrence of free markets. A total of 7,780 specimens belonging to six families and 14 species were collected. Muscidae was the most representative and diverse family, with 96.98% of all flies captured and four species. We observed that the assemblages were more abundant after the occurrence of the street markets (H = 6.56; df = 1; P < 0.01). Regarding the composition of the assemblies, 50% of the species were common to both treatments, with emphasis on the dominant species Musca domestica and Megaselia scalaris. This study reveals that free markets can modulate the structure and composition of flies’ assemblages in urban environments, including being able to offer health risks, considering that species of medical importance are related to this environment.

The article presents an examination of the movement trajectory of a single liquid drop of sludge containing water, oil, and iron scale in a swirling high-temperature gas flow. Taking into account a two-phase transition area from liquid water to vapor, temperature fields in a drop are determined, as is an algorithm for calculating the movement trajectory of a drop in a swirling gas flow when heating it up according to a two-phase area of water evaporation. When designing a drying chamber for drops of scale- and oil-containing sludge, a mathematical model helps predict its typical size as well as control the drying process for drops produced by a disk atomizer.
MULTI-CRITERIAL SCHEDULING OF A SPACECRAFT CONTROL CENTER’S OPERATION ON A DYNAMIC MODEL WITH DEAD-END CONTROLS
Authors:   V. A. Trapeznikov Institute of Control Sciences of Russian Academy of Sciences, Moscow, Russia, Корнеенко В. П.
Published: November 2023

The article is devoted to the solution of a problem of multi-criterial scheduling for execution of calculations of a large number of time-consuming computational tasks being solved simultaneously when implementing the time-sharing mode for their solutions in software and hardware’s multi-processor computing systems by the spacecraft control center. A dynamic recurrent model with dead-end controls is used to imple-ment the schedule of organizing software command information with control sectors. The criteria for selecting an efficient option of a daily schedule for the control sectors’ operation are determined, with the schedule being presented as time intervals of access to the computing system’s resources. Compared to the traditional algo-rithms of discrete optimization, the method of dead-ends control is more efficient in calculation in the frame-work of a dynamic model. An example of calculations conducted by the dead-end controls algorithm for the operational program, which is used on board of the spacecraft during a communication session, is given.

The article reviews literature on identification methods for parameters of regression models, including those based on Chebyshev metrics. The publications contain data on the development of an algorithm for the unambiguous definition of Chebyshev projection; a new method that combines Minkowskian distance and Chebyshev distance, with both being used as a similarity measure in the clustering process when grouping data; generalizations of particular goal setting for curves and surface fitting to the data observed or calculated as a result of replacing least squares with the Chebyshev norm; and integral estimates of the anthropogenic transformation of the territory using multidimensional statistical methods. Using the anti-robust method of estimation, the authors have developed a method to estimate unknown parameters of a regression piecewise linear risk function, whose aim is to solve a linear Boolean programming problem. The risk function of the dynamics of the price per square meter of living space of dwellings in the housing market in the Russian Federation is built using the least modules method and the anti-robust estimation method. Average pricing for silicate wall blocks, concrete floor slabs, and ready-mixed concrete are used as independent factors in the model. Both versions of the models built describe the dynamics of the output indicator profoundly, as evidenced by the high values of adequacy criteria, and therefore can efficiently solve the forecasting problems. It has been established that the number of maximum module errors of the risk model approximation is equal to three, i. e. the number of independent variables, when applying the anti-robust method.

North Bandung is an area where there are several tourist attractions, including the Dago Dream Park. The main road to several locations in North Bandung is via the road in front of Terminal Dago. For this reason, the purpose of this study was to collect data on PM2.5 and PM10 concentrations at both locations, namely in front of Terminal Dago and Dago Dream Park. Data collection was carried out for seven days, from Monday to Sunday, from 08.00 to 16.00 local time. To evaluate air quality in these two places, the national standard, namely PPRI No. 22 of 2021 and international standards from WHO were applied. The measurement results show that the concentrations of PM2.5 and PM10 in these two locations are still within the national standard. Meanwhile, when evaluated with WHO standards, PM10 concentrations in both locations are still within standard, but for PM2.5, there are several days where the air quality is out of the standard. The average concentrations of PM2.5 and PM10 during the 7 days of measurement at Terminal Dago are 19.9 μg/m3 and 21.6 μg/m3, respectively. While the average concentration of PM2.5 and PM10 during 1 week of data collection were 18.9 μg/m3 and 19.9 μg/m3, respectively. This means that the concentration of PM2.5 and PM10 at Terminal Dago is slightly higher than that of at Dago Dream Park. In addition, based on an evaluation using national standards, Dago Dream Park tourist attractions still have good air quality and are safe for local residents and tourists. From the data recorded at the Health Centre (Puskesmas), the number of ARI cases in the two locations in 2020 and 2021 is relatively not much different.

Crecidas de diseño del río Santa Cruz
Authors: Liscia Sergio Oscar , Cacik Pablo , De Dios Mariano , Vath Brenda
Published: November 2023

Esta publicación responde a una iniciativa de la Universidad Nacional de La Plata para que se cuente con información hidrológica e hidráulica de las crecidas del río Santa Cruz, las cuales son fundamentales para el diseño de las obras que se desarrollan en este río, en particular, de los Aprovechamientos Hidroeléctricos del río Santa Cruz. El río Santa Cruz, ubicado en la provincia homónima en el Sur de la Patagonia Argentina, tiene su cuenca con nacientes en el Campo de Hielo Patagónico Sur. Sus caudales se originan por la combinación de aportes de los glaciares, las lluvias y el derretimiento de nieve, los cuales interactúan con una gran cantidad de lagos y lagunas. El río presenta un régimen unimodal, con un marcado período de aguas altas en los meses de verano y hasta principios del otoño; y caudales mínimos al final de invierno y principios de la primavera. Este ciclo anual de caudales es interrumpido ocasionalmente por un hecho singular que se desarrolla en el suroeste del lago Argentino, y es el bloqueo de los aportes del brazo Rico hacia dicho lago ocasionado por el avance del glaciar Perito Moreno. Este fenómeno natural, provoca el incremento de los niveles de agua en el brazo Rico hasta que la carga hidráulica produce la rotura del bloqueo de hielo, con la posterior liberación de los volúmenes acumulados en pocos días hacia el lago Argentino, dando origen a un crecimiento repentino de este último y de los caudales que finalmente escurren por el río Santa Cruz. En este contexto, el entendimiento del sistema físico y sus mecanismos de interrelación, con la identificación de las principales variables intervinientes, resultan elementos críticos en lo relativo al conocimiento de la hidrología de crecidas y su posterior aprovechamiento para el diseño de diferentes obras y medidas no estructurales. En este libro se incluyen aspectos generales, tales como la recopilación de antecedentes y la caracterización de la cuenca del río Santa Cruz, así como también la determinación de crecidas de diseño con base probabilística y la estimación del hidrograma correspondiente a la crecida máxima probable. Asimismo, se aborda el análisis del impacto del cambio climático en las crecidas, el pasaje de los hidrogramas por los Aprovechamientos Hidroeléctricos del río Santa Cruz y la predicción de caudales máximos en el río. Se destaca la incorporación de capítulos específicos sobre el fenómeno de rotura del glaciar Perito Moreno y su impacto sobre los caudales del río Santa Cruz.
Minimax routing problem with a system of priority tasks
Authors: Chentsov A.G. , Chentsov A.A.
Published: November 2023

For a minimax routing problem with precedence conditions and cost functions that allow dependence on the list of tasks, we study the statement for which some of the tasks are allocated as first-priority ones. Other tasks can be started only after the fulfillment of priority tasks. The tasks themselves are connected with visiting megacities and, in particular, individual cities (terms corresponding to works in the field of solving the traveling salesman problem). One needs to find the extremum of arising two-stage problem with a minimax criterion, as well as the optimal compositional solution. In the paper, the optimal algorithm implemented on a PC is substantiated and built; a computational experiment is carried out. Possible applications may be related to some problems of aviation logistics in which it is required to ensure the visit of one vehicle (airplane or helicopter) to a system of aerodromes under a limited fuel reserve at each stage of the flight task; refueling is expected at points of visit (it is also assumed that a set of priority tasks is allocated).
Some problems of target approach for nonlinear control system at a fixed time moment
Authors: Ushakov V.N. , Ershov A.A. , Ushakov A.V. , Matviychuk A.R.
Published: November 2023

The game problem of target approach for nonlinear control system with a target set in a finite-dimensional phase space at a fixed time is studied. The problem is formulated and studied within the framework of concepts and constructions of the theory of positional differential games, created by N.N. Krasovskii and A.I. Subbotin in the second half of the 20th century. One of the central problems of the theory of positional differential games is the problem of calculating positional sets of uptake in convergence game problems. The paper investigates a key stability property in the theory of positional differential games, which is a characteristic of some closed sets in the space of positions of a controlled system that are convenient for the first player to conduct the game. It is important that this property is also characteristic for solvability sets in convergence problems: the inclusion of the concept of stability in research makes it possible to obtain analytical descriptions of solvability sets in some specific convergence problems and to develop algorithms for approximate calculation of the solution in a number of specific problems. Some modifications of the definition of a $u$-stable bridge in the considered convergence problem and a system of sets approximating the attainability set are given. Three specific problems on the convergence of mechanical systems are also presented, computer solutions are simulated, and graphical simulation results are presented.

Introduction: This study focuses on the effect of applying clay and compost on improving the quality of sandy soil in terms of the physical and chemical quality of the soil so that it can be a solution to problems in managing sandy soil so that the land can be productive and sustainable. Methods: This study used a factorial completely randomized design (RAL-F) with 3 treatment factors, namely: Depth (K1: 0-30 cm, K2: 30-60 cm), Dosage of compost (M1: 0 ton ha-1 as control, M2: 20 ton ha-1), Percentage of mineral soil (T1: 0% as control, T2: 25%, T3: 50%). Each treatment was repeated 4 times to obtain 48 pot units for the experiment. Data collection is carried out every 2 weeks for soil pH data. As for the other observation parameters taken in the last week of the incubation process, the data taken are chemical data in accordance with predetermined observation parameters which include soil physical properties such as bulk density, specific gravity, porosity, moisture content, pF value and basic chemical properties such as pH, organic matter, P-Available, N-Total. Results: Based on the results of laboratory analysis, it was shown that there was an increase in the average value of pH H2O and pH KCl every week, where initially the pH of H2O was 5.3 (1 MSI) to 5.9 (11 MSI) and the pH of KCl was from 5.1 (1 MSI) to 5.5 (11 MSI). This proves that the addition of organic matter and clay to the soil can increase the soil pH value. In addition to an increase in soil pH, there was also an increase in other chemical properties (BO, total-N and available-P) as well as soil physical properties (BI, BJ, Porosity and pF 2.5). Conclusion: the addition of clay soil and compost can improve the quality of sandy soil, especially the soil chemistry characteristics.

Introduction: Coconut palm sugar is a commercial product that continues to experience a trend of progress in both local and global markets. This triggers competition between manufacturers. Therefore, it is necessary to make an effort to diversify products to be able to increase competitiveness. However, this diversification will certainly incur costs, so it is necessary to conduct studies aimed at increasing the added value of coconut palm sugar products with and without iodine fortification and statistically different testing of them. Methods: Value added analysis was conducted using the Hayami method. The increase between coconut palm sugar products and their diversification is calculated from the difference in value add. Then the two groups of products were tested for significant differences with Mann Whitney. Results: from the results of the study it was found that the value add increasing in coconut palm sugar with iodine fortification products was 7% or Rp. 2,086 per kg. In addition, from the results of the Mann Whitney test, it is statistically proven that the value add of the two products is significantly different, where the smallest U value is smaller than the calculated Z value (-1 28.58). Conclusion: Value add and profit can be increased by diversifying coconut palm sugar products into iodine fortified palm sugar.

Introduction: Plant Growth Regulators (PGRs) play a role in regulating organogenesis and morphogenesis in shoots, roots, and callus formation. Color spectrum of light is one of the quality light factors that affects plant physiological processes. This study aimed to determine the effect of cytokinin and auxin on Murashige-Skoog (MS) medium and light on callus induction and proliferation of porang (Amorphophallus muelleri Blume.) var. Madiun1. Methods: This study used completely randomized design, with the first factor was PGRs (combination auxin and cytokinin) and the second was color spectrum of light (white light, blue light, and its combination) during incubation. Variables observed were emergence time, color, texture, structure and calli growth, also shoots emerging from calli. Results: The results showed an interaction between PGRs with a combination of light color spectrum on callus growth. The fastest callus growth occurred in combination 5.0 mg.l-1 6-benzyl amino purine (BAP) with 0.2 mg.l-1 naphthalene acetic acid (NAA) which was incubated in a combination of white and blue light for 16 hour irradiation. The combination 5.0 mg.l-1 BAP with 0.2 mg.l-1 NAA was able to induce callus emergence time, and the shoots appearing were faster, whereas combination of white and blue light was able to accelerate callus emergence from bulbil and adventitious shoots emergence. Conclusion: The combination of white and blue light color spectrum for 16 hours irradiation can accelerate callus emergence from bulbil and adventitious shoots emerging from calli, and interaction with combination of 5.0 mg.l-1 BAP and 0.2 mg.l-1 NAA can accelerate porang’s callus growth.

Introduction: Fructooligosaccharides (FOS) and inulin are some of the many bioactive elements that are often used in functional food products. FOS and inulin compounds have various benefits that can be used as low-calorie food products and as raw materials for making fructose syrup. So that FOS and inulin compounds have the potential to be developed into functional drinks. The purpose of this study was to evaluate the quality characteristics of carbohydrates in functional drinks FOS and inulin, as well as to determine the level of preference or feasibility of a product so that it can be accepted by panelists (consumers). Method: The research was conducted in two stages. The first stage was the preliminary stage which includes the production of FOS with PDA solid media, extraction of inulin from dahlia tubers, and the formulation of FOS and inulin functional drinks. The second stage was the main research by conducting chemical quality characteristics in the form of reducing sugar content, fructose, sucrose, glucose, inulin, soluble fiber, and organoleptic tests. Results: Based on the observations, several characteristics of the carbohydrate quality of functional drinks based on FOS and inulin were obtained, namely reducing sugar levels ranging from 0.22 to 5.60%. Fructose and sucrose levels of functional drinks based on FOS and inulin ranged from 1-2%, while glucose levels were between 0.1-2%. The levels of inulin and soluble fiber in functional drinks based on FOS and inulin were 55-86% and 2-5%, respectively. Also, the pH value of functional drinks based on FOS and inulin ranged from 5-7. Conclusion: The results of the organoleptic test showed that the best functional drink based on FOS and inulin was in the AD treatment, namely the addition of 7 grams of inulin and 50 ml of fructooligosaccharides.

Introduction: Soybean is one of the main sources of vegetable protein. Seventy percent of the soybean needs in Indonesia is still imported, due to the low crop productivity and the declining area of soybean planting. Sonic bloom technology is an alternative to increase soybean productivity. This study aims to determine the pattern of the relationship between foliar fertilization intervals in the use of sonic bloom technology with soybean varieties. Method: The research used a factorial experiment using a randomized block design (RBD). The first factor is the interval of using sonic bloom, I5: 5-day interval, I10: 10-day interval, and I15: once every 15 days. The second factor was soybean varieties, VA: Anjasmoro, VD: Dega-1, and VM: Mallika (black soybean). The data obtained were analyzed for Analysis of Variance with the Fα = 0.05 test followed by the 5% Honest Significant Difference (HSD) test and correlation regression analysis.The results showed that different soybean varieties have different responses to plant length, number of leaves and leaf area at different intervals of sonic bloom exposure. Result: Soybean plants with thicker hairs (trichomes) such as the Dega-1 variety require the use of sonic bloom technology with shorter intervals compared to varieties with sparse hairs such as Anjasmoro and Mallika black soybeans. Conclusion: The use of sonic bloom technology was able to increase the productivity of soybean varieties Anjasmoro, Mallika and Dega-1 each by 68.3%; 48.3% and 10.5%.

For the problem of obstacle avoidance trajectory planning of a robot arm, a robot arm obstacle avoidance method based on a genetic algorithm is proposed. It is based on the two problems that the motion process can avoid obstacles and the motion process is more stable and efficient. First, the motion of each joint is planned as a sixth-degree polynomial, and the coefficients of the sixth-degree term are set as the pending parameters, and the motion of each joint is changed by changing the pending parameters. Then, the fitness function is then constructed by calculating the collision detection, angular velocity limit detection, acceleration limit detection, and the total trajectory length and rotation angle for each joint. Finally, the fitness function is optimised using a genetic algorithm to obtain smooth, continuous, and collision-free trajectories. Matlab simulation experiments show that this method can obtain the optimal or suboptimal trajectory without collision.

Published: November 2023

Os núcleos de inovação e tecnologia (NITs), criados por lei e mantidos nas instituições de ciência e tecnologia (ICTs), têm papel importante na transferência de inovação e de tecnologia, assim como geram conhecimento e auxiliam o desenvolvimento do país; portanto, a gestão da inovação é fundamental para o alcance do papel desses núcleos. O objetivo desta pesquisa foi analisar o desenvolvimento da gestão de inovação em NITs implementados no Brasil. Para tanto, realizou-se uma pesquisa descritiva e exploratória, com abordagens qualitativa e quantitativa, por meio do método de estudo de casos múltiplos, com levantamento bibliográfico, documental e normativo, aplicação de questionário eletrônico e realização de entrevistas semiestruturadas. Observou-se que, até então, não há um modelo ideal de gestão para o NIT, porém, o aprimoramento da gestão da inovação passa por três pilares (divulgação, interação e planejamento), que necessitam de fortalecimento para mudar a realidade social do país, seja no âmbito local, regional ou nacional.
SODIUM HYPOCHLORITE ACCIDENTS: A REVIEW ARTICLE

Endodontic failure is caused by microorganisms that colonize
necrotic tissue in the root canal system (Mohammadi & Yazd,
2008), the microora of which is dominated by obligate
anaerobes (Zehnder, 2006). Organisms must be removed from
the entire canal in order for endodontic treatment to be
successful (Mohammadi & Yazd, 2008). Mechanical
preparation is supplemented with irrigant to disinfect the
entire canal space (Baser Can, Karapinar Kazandag, &
Kaptan, 2015), and the ideal irrigant should dissolve necrotic
tissue, inactivate endotoxin, prevent smear layer formation,
and be antimicrobial all at the same time (Zehnder, 2006).
These conditions are met by sodium hypochlorite, the most
extensively used and widely available irrigant (Chaudhry,
Wildan, Popat, Anand, & Dhariwal, 2011). However, it is a
solution that is not without risk.{4}
