Adaptive fuzzy-neural network effectively disturbance compensate in sliding mode control for dual arm robot

In this study, an Adaptive Backstepping Sliding Mode Controller (ABSMC) is introduced based on the Radial Basis Function (RBF) neural network and a fuzzy logic modifier. The proposed method is used to control a Dual-Arm Robot (DAR) – a nonlinear structure with unstable parameters and external disturbances. The control aims to track the motion trajectory of both arms in the flat surface coordinate within a short time, maintaining stability, and ensuring that the tracking error converges in finite time, especially when influenced by unforeseen external disturbances. The nonlinear Backstepping Sliding Mode Control (BSMC) is effective in trajectory tracking control; however, undesired phenomena may occur if there are uncertain disturbances affecting the system or model parameters change. It is proposed to use a neural network to estimate a nonlinear function to handle unknown uncertainties of the system. The neural network parameters can be adaptively adjusted to optimal values through adaptation rules derived from Lyapunov's theorem. Additionally, fuzzy logic theory is also employed to adjust the controller parameters to accommodate changes or unexpected impacts. The performance of the Fuzzy Neural Network Backstepping Sliding Mode Control (FNN-BSMC) is evaluated through simulation results using Matlab/Simulink software. Two simulation cases are conducted: the first case assumes stable model parameters without uncertain disturbances affecting the joints, while the second case considers a model with changing parameters and disturbances. Simulation results demonstrate the effective adaptability of the proposed method when the system model is affected by various types of uncertainties from the environment

Предрассудок как предмет междисциплинарного исследования

The subject of the study is the phenomenon of prejudice, studied in various specialized discourses and con-texts – linguistic, philosophical and psychological. In this regard, the problem under study can quite reasonably be attributed to the objects of multidisciplinary research. An attempt has been made to consider and rethink the well-known term and the problems behind it in a fairly wide field of view. An additional objective of the study is to justify the need to rethink both the very nature of prejudice and the role it actually plays. In accordance with the aim of the study, a wide range of methods was used, used in specific local areas, but requiring a certain general unifying methodological link, technique or principle. This, according to the author, is the so-called sys-temic or rational eclecticism, used in various fields of humanities. Its use allowed, within certain limits, to com-bine ideas contained in relatively localized scientific fields, as well as to turn to artistic and literary genres of creativity as an illustrative background. The main conclusion of the study was the proposition that the phenom-enon of prejudice contains not only a negative emotional and affective connotation, but can also be used as an effective tool to counter undesirable phenomena in specific cognitive, psychological, sociocultural discourses and areas of behavior. The main result that can be used in solving actual specific cognitive, ideological and behavioral problems is proposed to understand the phenomenon of prejudice, where an unprejudiced attitude should be formed towards the prejudice itself, that is, this would mean actually getting rid of prejudice in the opinion regarding the prejudice itself as a phenomenon.

ВИНОГРАДАРСТВО ЧЕЧЕНСКОЙ РЕСПУБЛИКИ В СОВЕТСКОЕ ВРЕМЯ (1954−1991), УСПЕХИ И ПРОБЛЕМЫ

The article discusses issues related to the unsuccessful introduction of viticulture in the administrative regions of the Chechen Autonomous Soviet Socialist Republic, where grapevine culture was new or non-traditional. These regions are Malgobeksky, Kurchaloevsky, Shalinsky, Grozny-Selsky districts. It has been established that the main reason for the spread of viticulture was the state’s desire to employ unemployed population and the high profitability of the industry. For this purpose, collective and state farms, which previously specialized in the cultivation of grain crops, feed production and livestock breeding, were restructured. The state allocated sufficient funds and material resources for the formation and functioning of a new sub-sector of the agro-industrial complex of the republic in these areas. However, hopes were not justified. The reasons that contributed to attempts to accelerate the introduction of grapevine culture in the “new” regions of the republic, as well as the failure of work in this direction, have been identified. An analysis of the activities of farms involved in the development of viticulture in these areas was carried out. Excesses of higher authorities have been established in planning for wine state farms the volume of new plantings of vineyards, achieving the planned yield and gross grape harvest, as well as planned targets for financial and economic indicators, and in the absence of proper consideration of soil and climatic factors and their compliance with the economic and biological characteristics of the grape culture. As a result, it was revealed that this crop was not adaptable to local conditions, which was reflected in the low survival rate of plantings, the high sparsity of plantings and their unprofitability for further exploitation. All wine farms were unprofitable. The factor of psychological incompatibility of the local population to this culture also had a certain influence. At the same time, all these undesirable phenomena intensified due to the fact that they coincided with the time of the weakening of the foundations of the state under the slogans of perestroika, the fight against alcoholism and drunkenness, and later − with the tragic events of the collapse of the USSR and their negative consequences. It is concluded that the widespread involvement of “new” regions in the development of viticulture was not a fully thought-out campaign. This led, in particular, to disastrous results: the vineyards were written off before they reached productive age. In the future, introducing grapevine culture here is not economically feasible.

Miniaturized computational spectrometer based on two-photon absorption

On-chip spectrometers hold significant promise in the development of laboratory-on-a-chip applications. However, the spectrometers usually require extra on-chip or off-chip photodetectors (PDs) to sense optical signals, resulting in increased footprints and costs. In this paper, we address this issue by proposing a fully on-chip spectrometer based on two-photon absorption (TPA) in a simple micro-ring resonator (MRR) configuration. While TPA is a commonly undesired phenomenon in conventional silicon devices due to its attached absorption losses and nonlinearity, we exploit it as a powerful and efficient tool for encoding spectral information, instead of using additional PDs. The input spectrum can be reconstructed from the sensed TPA current. Our proposed spectrometer achieves a bandwidth of 10 nm with a resolution of 0.4 nm while occupying a small footprint of only 16×16µm2, and the bandwidth can be further improved through several cascaded MRRs. This advancement could enable forward fully integrated and miniaturized spectrometers with low cost, which holds far-reaching applications in in situ biochemical analysis, remote sensing, and intelligent healthcare.

Dissipative PID control for uncertain positive Roesser system under the try-once-discard protocol

This paper addresses the problem of dissipative proportional–integral–derivative (PID) control for the delayed positive Roesser system with interval uncertainties under the try-once-discard (TOD) protocol. To alleviate the undesired data congestion phenomenon in the shared communication network, the TOD protocol is introduced to regulate which sensor node could release its measurement at each transmission instant. An output-feedback-based PID controller is designed for the two-dimensional (2-D) system with TOD protocol. Based on the co-positive Lyapunov–Krasovskii function method, sufficient criteria in the linear programming form are attained to ensure the positivity, 2-D (ζ,η)-γ-dissipativity and robust asymptotic stability of the closed-loop system. Finally, an illustrative example is given to show effectiveness of the PID control scheme designed.

Edible chitosan-based Pickering emulsion coatings: Preparation, characteristics, and application in strawberry preservation

The long-term application of plant essential oils in food preservation coatings is limited by their poor water solubility and high volatility, despite their recognized synergistic antimicrobial effects in postharvest fruit preservation. To overcome these limitations, a Pickering emulsion loaded with thyme essential oil (TEO) was developed by utilizing hydrogen bonding and electrostatic interactions to induce cross-linking of chitosan particles. This novel emulsion was subsequently applied in the postharvest storage of strawberries. The shear-thinning behavior (flow index <1) and elastic gel-like characteristics of the emulsion made it highly suitable for spray application. Regarding TEO release, the headspace concentration of TEO increased from 0.21 g/L for pure TEO to 1.86 g/L after two instances of gas release due to the stabilizing effect of the chitosan particles at the oil-water interface. Notably, no phase separation was observed during the 10-day storage of the emulsion. Consequently, the emulsion was successfully employed for the postharvest storage of strawberries, effectively preventing undesirable phenomena such as weight loss, a decrease in firmness, an increase in pH, and microbial growth. In conclusion, the developed Pickering emulsion coating exhibits significant potential for fruit preservation applications, particularly for extending the shelf life of strawberries.

Method of characteristic modes

In recent years, the number of works on the method of characteristic modes and problems solved with its help has increased significantly, which indicates an awareness of its potential and, in connection with this, a growing interest in this approach. The attractiveness of this method lies in the fact that it provides a clear physical picture of the occurring phenomena and the ensuing opportunity to build on this basis methods for creating structures with the required parameters and combating undesirable phenomena. Unfortunately, in the Russian-speaking segment of applied electrodynamics, very few researchers are engaged in the development and application of the approach under consideration. The purpose of this work is to increase the interest of Russian-speaking researchers in the method of characteristic modes. A review of publications devoted to the method of characteristic modes, both early, fundamental and already classic, associated with the names of R.J. Garbacz and R.F. Harrington, and those which have appeared in recent years and offer generalizations of the method for various electrodynamic structures, has been carried out. This includes composite structures consisting of a set of metal and dielectric bodies of various configurations. In addition, variants of the method for antenna arrays of both infinite periodic and finite sizes have been considered. Issues related to modal tracking problems, orthogonal properties of characteristic modes and improving the convergence of solutions have been considered. Much attention is paid to works containing solutions to specific practical electrodynamic problems using the method of characteristic modes. The works have been shown, in which simple and effective approaches based on the method of characteristic modes are given for the design of a ship's HF antenna system, on-board aircraft antennas in the short-wave region, antennas placed on the platform of a battle tank, and the concept of designing an antenna for an electrically small-unmanned aerial vehicle has been presented. Options for solving the problem of reducing the mutual coupling of elements in antenna arrays have been shown. Attention is paid to MIMO antennas, antennas for smartphones, systems with specified radiation zeros, antennas using metasurfaces. According to the authors, the characteristic mode method, taking into account the increasing possibilities of its application, will make it possible to take the next step in the development, analysis or synthesis of new antenna structures that meet ever-increasing modern requirements.

The Role of Islam in Alleviating Poverty: An Analytical Study

Poverty is an undesirable social phenomenon whose existence and expansion in society lead to all-around miserable consequences in the short and long term. This ominous phenomenon is condemned in all human religions and cultures, and various ways and methods have been proposed to eradicate it from society. Islam considers a life with prosperity and peace as the natural right of human beings and confronts the obstacles to the realization of this goal. Therefore, it gives teachings to its followers that, by following them, they will enjoy a life of full joy and contention, and their physical and mental health will be guaranteed. Undoubtedly, poverty is one of the biggest concerns of all human societies and economic systems. Poverty is one of the negative phenomena that pose a threat to life. Economic schools of thought have presented different ways to deal with it, but so far, they have not yet succeeded in eliminating poverty from human lives. Its occurrence is called an unpleasant complication. Poverty is one of the most important long-standing issues in developed and developing countries, including Islamic countries. To solve the problem of poverty, many studies have studied the factors affecting poverty. The purpose of this research is to identify the role of Islam in reducing poverty. In the question of the research, it is stated that what is the role of Islam in reducing poverty, and what are its recommendations for reducing poverty? The research method in this study is descriptive-analytical, and the required information was collected from library sources and a combination of the Delphi method.

Ca-dimers, solvent layering, and dominant electrochemically active species in Ca(BH4)2 in THF

Divalent ions (Mg, Ca, and Zn) are being considered as competitive, safe, and earth-abundant alternatives to Li-ion electrochemistry, but present challenges for stable cycling due to undesirable interfacial phenomena. We explore the formation of electroactive species in the electrolyte Ca(BH4)2∣THF using molecular dynamics coupled with a continuum model of bulk and interfacial speciation. Free-energy analysis and unsupervised learning indicate a majority population of neutral Ca dimers and monomers with diverse molecular conformations and an order of magnitude lower concentration of the primary electroactive charged species – the monocation, CaBH4+\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${\\rm{CaBH}}_{4}^{+}$$\\end{document} – produced via disproportionation of neutral complexes. Dense layering of THF molecules within ~1 nm of the electrode surface strongly modulates local electrolyte species populations. A dramatic increase in monocation population in this interfacial zone is induced at negative bias. We see no evidence for electrochemical activity of fully-solvated Ca2+. The consequences for performance are discussed in light of this molecular-scale insight.

Liquid Flow Patterns and Particle Settling Velocity in a Taylor-Couette Cell Using Particle Image Velocimetry and Particle Tracking Velocimetry

Summary Controlling the downhole pressure is an important parameter for successful and safe drilling operations. Several types of weighting agents (i.e., high-density particles), traditionally barite particles, are added to maintain the desired density of the drilling fluid (DF). The DF density is an important design parameter for preventing multiple drilling complications. These issues are caused by the settling of the dense particles, an undesired phenomenon also referred to as sagging. Therefore, there is a need to understand the settling characteristics of heavy particles in such scenarios. To this end, simultaneous measurements of liquid phase flow patterns and particle settling velocities have been conducted in a Taylor-Couette (TC) cell with a rotating inner cylinder and stationary outer cylinder separated by an annular gap of 9.0 mm. Liquid flow patterns and particle settling velocities have been measured using particle image velocimetry (PIV) and particle tracking velocimetry (PTV) techniques, respectively. Experiments have been performed by varying the rotational speed of the inner cylinder up to 200 rev/min, which is used in normal drilling operations. Spherical particles with diameters of 3.0 mm or 4.0 mm and densities between 1.2 g/cm3 and 3.95 g/cm3 were used. The liquid phases studied included deionized (DI) water and mineral oil, which are the basic components of a non-Newtonian DF with a shear-thinning viscosity. The DF is a mud-like emulsion of opaque appearance, which impedes the ability to observe the liquid flow field and particle settling in the TC cell. To address this issue, a solution of carboxymethyl cellulose (CMC) with a 6% weight concentration in DI water was used. This non-Newtonian solution displays shear-thinning rheological behavior and was used as a transparent alternative to the opaque DF. For water, PIV results have shown wavy vortex flow (WVF) to turbulent Taylor vortex flow (TTVF), which agrees with the flow patterns reported in the literature. For mineral oil, circular Couette flow (CCF) was observed at up to 100 rev/min and vortex formation at 200 rev/min. For CMC, no vortex formation was observed up to 200 rev/min, only CCF. The settling velocities for all particles in water matched with the particle settling velocities predicted using the Basset-Boussinesq-Oseen (BBO) equation of motion. For mineral oil and CMC, the results did not match well with the predicted settling velocities, especially for heavy particles due possibly to the radial particle migration and interactions with the outer cylinder wall.

Programming crack patterns with light in colloidal plasmonic films

Crack formation observed across diverse fields like geology, nanotechnology, arts, structural engineering or surface science, is a chaotic and undesirable phenomenon, resulting in random patterns of cracks generally leading to material failure. Limiting the formation of cracks or “programming” the path of cracks is a great technological challenge since it holds promise to enhance material durability or even to develop low cost patterning methods. Drawing inspiration from negative phototropism in plants, we demonstrate the capability to organize, guide, replicate, or arrest crack propagation in colloidal films through remote light manipulation. The key consists in using plasmonic photothermal absorbers to generate “virtual” defects enabling controlled deviation of cracks. We engineer a dip-coating process coupled with selective light irradiation enabling simultaneous deposition and light-directed crack patterning. This approach represents a rare example of a robust self-assembly process with long-range order that can be programmed in both space and time.

Current study on human-computer interaction in machine learning

Machine learning has become one of the research hotspots at home and internationally due to the continued growth of artificial intelligence, and the application of machine learning is more and more widely developed. In the process of applying machine learning methods to real problems, there are defects that lead to biased results. This paper discusses the importance and necessity of human-machine interaction in the application of machine learning methods, as well as where human-machine interaction occurs, and puts forward two questions: "whether human should interact with machine in the process of machine learning" and "how to make machine learning have better performance". To answer the above two questions, this paper concludes that in the application of machine learning methods, people with certain professional knowledge can get better results in the machine learning process. Further, when machine learning is applied to the real world, there are some flaws that lead to failure or unsatisfactory results, and this paper proposes a way to improve this undesirable phenomenon by involving people in the machine learning process. Finally, this paper summarizes the main shortcomings of current machine learning, clarifies the development direction of machine learning that must be anthropocentric, and expresses some views on machine learning.

Modification of rotor modal properties based on structural changes in the stiffness of its bearings and shaft

The rotor structures are fundamental mechanical systems that realize the transfer of rotary motion in technical devices and systems. In some operating regimes, the rotor systems are often subjected to undesirable and damaging phenomena resulting in resonant state. The ability to prevent or reduce the level of unwanted rotor vibrations in the given operating mode is an important task in the process of structural design of rotor structures. In general, the dynamic properties of rotor systems depend on their spatial properties - geometric parameters and material properties, i.e. distribution of mass and stiffness properties of rotor structures. For the structural design of the rotor or its structural modification, which will allow the redistribution of its spatial properties (mass and stiffness), two approaches based on changing the bearing stiffness and also on the shaft stiffness are presented in this paper. The main goal for modifying the spatial properties of the rotor is to get the critical rotor speed out of the operating speed range.

For the development of an efficient management in the contemporary school, based on a modern value system and the valorization of the pupil’s personality, an important role in the educational system is played by extracurricular activities, which can contribute to the development of the student, strengthen the relationship between children and parents, but also mitigate the impact of undesirable phenomena, such as, for example, school dropout. In this article, the author exposes the analysis of the results of sociological research, which explores the ability of extracurricular activities to contribute to increasing the quality of training. It analyzes that compartment, which reveals extracurricular activity through the prism of the opinions of parents and tries to highlight the need to attract them as important actors in the school life of children.

Fiducial marker and blob detection-based motion compensation algorithm for Thermoelastic Stress Analysis measurements

Non-contact techniques for measuring stress and strain on structures offer advantages including preservation of structural integrity, remote and continuous monitoring, full-field measurement capability, non-destructive testing, and adaptability to various materials. Among them, thermoelastic stress analysis is one of the most established non-contact techniques to measures stress distributions in structures by analysing temperature-induced deformations. This research proposes a methodology for the compensation of the edge effect, a undesirable phenomenon resulting from rigid displacements in the analysed structure when using thermoelasticity approach. These displacements give rise to virtual stress distributions along the sample’s edges. For this purpose, a fiducial marker was used to track rigid displacements in thermal images, that were then processed using a blob detection algorithm, for compensating for edge effects under different loading conditions. The algorithm was capable of measuring the displacement of a sample at different frequencies (5-25Hz) and distances from the target (300-600 mm), with the lowest uncertainty of 0.2 mm. The impact of compensation was found The impact of the compensation was found to be significant, especially at frequencies lower than 10 Hz, where the displacement was the highest.

Fractional-Order Sliding-Mode Control and Radial Basis Function Neural Network Adaptive Damping Passivity-Based Control with Application to Modular Multilevel Converters

This paper proposes a hybrid control scheme that combines fractional-order sliding-mode control (FOSMC) with radial basis function neural network adaptive damping passivity-based control (RBFPBC) for modular multilevel converters (MMC) under non-ideal operating conditions. According to the passive control theory, we establish the Euler–Lagrange (EL) models of positive and negative sequences based on the unbalanced grid. A passivity-based controller that satisfies the energy dissipation law is designed. To enable rapid convergence of the system energy storage function, a radial basis function neural network (RBFNN) is introduced to adjust the injection damping adaptively. Additionally, a fractional-order sliding-mode controller (FOSMC) is designed. The fractional-order sliding mode surface used can improve tracking performance, and effectively suppressed the undesirable chattering phenomenon compared to the traditional sliding-mode control (SMC). Finally, combining the two control methods can effectively solve the issue of passivity-based control (PBC) being too dependent on parameters. The proposed hybrid control scheme enhances the ability of the system to resist disturbances, and improves its overall robustness. Simulation results demonstrate the feasibility and effectiveness of this control method.

Evolution of Microstructure and Crystallographic Texture in Deformed and Annealed BCC Metals and Alloys: A Review

Dislocation slips, twinning, shear banding (SBs), strain localization, and martensite formation are a few deformation modes that are activated in BCC metals and alloys. Strain, strain rate, and deformation temperature are other parameters that determine the activation of deformation modes in BCC alloys. This review focuses on several BCC alloys, such as beta-titanium (β-Ti), tantalum (Ta), and ferritic stainless steels (FSSs), all of which exhibit differences in deformation behavior. These alloys often undergo thermo-mechanical processing (TMP) to enhance their mechanical properties. TMP leads to the evolution of deformation-induced products, such as SBs, strain-induced martensite (SIM), strain localizations, and mechanical/deformation twins (DTs) during plastic deformation, while also influencing crystallographic texture. The deformation modes in β-Ti depend upon the stability of the β-phase (i.e., β-stabilizers); low-stability alloys show the formation of SIM along with slips and twins, whereas in highly stable β-Ti alloys, only slip+twin modes are observed as the primary deformation mechanisms. In the case of Ta, slip activity predominantly occurs on {110} planes, but it can also occur on planes with the highest resolved shear stress. The breakdown of Schmid’s law or non-Schmid behavior for Ta and Ta-W alloys has been discussed in detail. The cold rolling (CR) of FSSs results in the formation of ridges, which is an undesirable phenomenon leading to very low formability. The microstructures of the rolled sheets consist of elongated ferrite grains with in-grain SBs, which are preferentially formed in the γ-fiber-oriented grains. The formation of finer grains after recrystallization improves both the mechanical properties and ridging resistance in FSS. Therefore, this review comprehensively reports on the impact of TMP on the microstructural and crystallographic texture evolution during the plastic deformation and annealing treatment of β-Ti, Ta alloys, and FSSs in BCC materials, using results obtained from electron microscopy and X-ray diffraction.

Dissipative filtering for uncertain positive Roesser system under the try-once-discard protocol

This article addresses the problem of dissipative filtering for the delayed positive Roesser system with uncertainties under the try-once-discard communication protocol. To estimate the output of the addressed two-dimensional system, both positive lower- and upper-bounding filters are constructed, where the signals from the sensor nodes to the remote filters are transmitted through a shared communication network. To avoid the undesired data congestion phenomenon, the try-once-discard protocol is implemented to dynamically schedule the transmission sequence of the sensor nodes. Then, sufficient conditions are derived to design appropriate filters ensuring that the filtering error systems are positive, two-dimensional [Formula: see text]- γ-dissipative, and asymptotically stable. Finally, one numerical example is presented to demonstrate effectiveness of the designed filters.

Заимствования из русского языка в тувинской речи как способ эвфемизации

The paper considers Russian loanwords in Tuvan speech, the ones that are used as euphemisms. The analysis was conducted by utilizing recordings of speech in the Tuvan language collected from the Internet, social networks, and instant messengers, as well as through observations of the daily speech of contemporary speakers of the Tuvan language. The borrowings identified as euphemisms can be divided into five groups: (1) denoting various diseases and related phenomena, (2) related to the physiological, anatomical, and sexual spheres, (3) associated with the concept of death, (4) associated with the designation of undesirable social phenomena, and (5) associated with the ethical and aesthetic perception of a person. The first group comprises borrowed names of diseases and related concepts. Native speakers tend to regard medical terms as uncomfortable and rude. The second group encompasses words perceived as unpleasant, disgusting, and shameful, such as words and phrases related to human physiology and the sexual sphere. The absence of these lexemes in Tuvan language dictionaries serves as evidence of their exclusive usage in colloquial discourse. The third group represents the means of euphemistic portrayal of death, which is a common characteristic found in all cultures. The fourth group includes euphemisms linked to societal challenges and undesirable social phenomena. The fifth comprises euphemisms that reflect the evolving perceptions of individuals in contemporary Tuvan society, with transformations caused by the modern level and life expectancy, changing social roles, and changing aesthetic ideas.

Exploring the Application of Big Data Technology in Macroeconomic Management and Strategy Formulation

Abstract The initiative of macroeconomic management and regulation helps to eliminate such undesirable phenomena as unfair competition and malicious competition in the market and effectively improves the fairness and transparency of the economic market. This paper takes the importance of macroeconomic management as a guide and analyzes the value of the application of big data technology in macroeconomic management. Taking China’s macroeconomic data from 2012 to 2024 as the research object, a macroeconomic trend forecasting model is established by combining the C4.5 algorithm of time series. Combined with the FAVAR model, the SV-TVP-FAVAR model is established to study the impact of macroeconomic policy uncertainty on the macroeconomic system. The model cumulative return, trend prediction, aggregate impulse effect, and stage response characteristics are used as indexes for model evaluation. The cumulative return of the macroeconomic trend prediction model can reach up to 82.29%, the incremental GDP is only 920 million yuan lower than the actual macroeconomic value, and the great value of the impact of quantitative tools and price tools on economic growth is 0.369 and 0.359, respectively. The analytical model of macroeconomic data is constructed on the basis of big data technology, which facilitates access to the trend of the macroeconomic changes and the influencing factors and provides a reference for the optimization of the macroeconomic management strategy to provide a reference.
