The Government of the Russian Federation in the system and structure of the Federal Executive authorities of the Russian Federation: administrative and legal aspect

The subject is the conceptual aspects and regulatory legal acts defining the legal status of the Government of the Russian Federation. The article reveals the signs of executive authorities. The analysis of the provisions of regulatory legal acts affecting the legal status of the Government of the Russian Federation is carried out. The relevance of the article is to identify the existing legal uncertainty of the place and role of the Government of the Russian Federation in the exercise of executive power.The theoretical basis is made up of scientific works by scientists and practitioners in the field of public law, whose research interests focused on issues related to the study of the system of executive authorities in Russia. The main purpose of the article is to analyze the legal status of the Government of the Russian Federation and to draw conclusions about its place in the system and structure of federal executive authorities and its role in public, including executive, government. In the course of the research, legal methods (formal-logical, comparative-legal), as well as the methodology of system analysis and expert analysis were used. As a result of the analysis of constitutional and administrative legislation in the field of public administration, significant features of the Government of the Russian Federation have been identified, interaction and relationship with federal executive authorities have been characterized, and problematic aspects of its legal status have been identified. The statement in the Federal Law "On the Government of the Russian Federation" that the Government of the Russian Federation is part of the system of federal executive authorities does not seem sufficiently justified, taking into account the content of the Basic Law of Russia and the acts of the President. The novelty of the article lies in substantiating the need to verify the provisions of regulatory legal acts on the legal status of the Government of the Russian Federation for their compliance with the Constitution of the Russian Federation, as well as the need for interpretation by the Constitutional Court of the Russian Federation, taking into account the amendments to the Constitution of the Russian Federation introduced in 2020.

Sustainable and optimized power solution using hybrid energy system

This research study aims to develop and implement a sustainable and effective power solution for metropolises with a power demand ranging from 2.5 to 25 MW. The primary objective is to create a hybrid energy system (HES) that integrates various power sources, such as fuel cells and solar photovoltaic (PV), with the existing utility grid, thereby satisfying energy needs while minimizing dependency on conventional fuel-based energy sources like coal and oil. To achieve this, a thorough examination of the energy demand, availability of renewable resources, and current power infrastructure is conducted. This examination focuses on optimizing the design of the HES by considering critical factors such as grid integration, power generation capacity, energy storage capacity, and control strategies. The feasibility and performance of the proposed HES are assessed using a combination of simulation tools, mathematical modeling, and system analysis methodologies. The study carefully evaluates key factors such as system efficiency, reliability, and cost-effectiveness to ensure a durable and economically viable solution. The abstract of this study emphasizes the main quantitative findings, such as a 25% decrease in energy costs and a 30% boost in overall system efficiency, positioning the HES as an attractive choice for sustainable energy management. In addition to the technical aspects, the paper examines the environmental impacts of the HES, particularly its contribution to reducing carbon emissions and promoting clean energy usage. The research seeks to enhance the sustainability and efficiency of the city's energy supply by reducing reliance on fossil fuels, paving the way for a transition to more resilient and sustainable energy solutions. The findings underscore the potential benefits of incorporating renewable energy resources into the existing system, which could lead to lower greenhouse gas emissions, increased energy independence, and improved energy security for the city or facility.

Operational Noise Abatement Through Control of Climb Profile on Departure

This work introduces a noise abatement procedure for reducing aircraft community noise during departures based on the control of climb profiles via procedural level-offs. The proposed procedure consists of enforcing an altitude restriction along a departure path such that aircraft maintain level flight when overflying strategically selected regions. During this level segment, thrust demand is lower than during climbing flight, which results in lower engine noise. However, this effect must be balanced with the lower aircraft altitude in the level segment, which may reduce the distance between aircraft and observers. Thus, a systematic analysis methodology is needed to design an effective noise abatement procedure based on this technique, which has been developed and is presented in this paper. Modeling results show potential undertrack peak A-weighted noise level reductions of 2–4 decibels for both narrowbody and widebody aircraft in the level-off area depending on the level-off altitude and an associated increase of 1.5–6 decibels in the region where the climb is resumed. An example application of this procedure is demonstrated at Boston Logan Airport, with cumulative changes in noise impacts being assessed for one full day of operations. In this example application, fuel burn penalties are estimated at 37 pounds for a representative narrowbody operation and 142 pounds for a representative widebody operation.

CLOUD COMPUTING INFRASTRUCTURE DATA SECURITY: AN OPTIMIZED VIRTUALIZATION MODEL

The study suggests using an improved and robust virtualization model to apply an intelligent-based design to data security monitoring in a cloud computing infrastructure. The primary problem with cloud computing, the concurrently concerning malicious activity, makes this technology notable. When we discuss an architecture that allows for easy, on-demand network access to a shared pool of reconfigurable computing resources—such as servers, networks, storage, apps, and services—we are referring to cloud computing. This requires little administration work or communication between the service provider and customer to quickly deploy and discharge. A virtualized approach was created in this work to improve the monitoring of data security. Adopting the Structured System Analysis and Design Methodology, dataflow diagrams, use-case diagrams, sequence diagrams, and diagrams created with the Unified Modelling Language (UML) were utilized to accomplish the desired design. Robust repositories provided five hundred (500) datasets, of which thirty percent were used for training and seventy percent were used for testing. The number of adopted technologies, the number of adopted design tools, the number of adopted algorithms, and the number of tested records were all used as parameters to analyze and assess the performance of both systems. According to the performance review, the new system performed better than the old one, achieving an accuracy rate of 1.07% as opposed to the old system's 0.48% accuracy rate. The recently created model focused specifically on financial fraud and was intended to detect fake data in cloud computing infrastructure. Because financial frauds against property involve the illegal transfer of property ownership for an individual's personal use and benefit, this study could be helpful to corporate organizations, anti-corruption agencies, and researchers who have a keen interest in the subject matter. Additionally, the new system was further optimized with the use of deep neural networks and logistic regression techniques.

TRANSFORMING CLOUD COMPUTING DATA SECURITY WITH AN INNOVATIVE VIRTUALIZATION MODEL

This study presented an optimized approach to Data Security Monitoring in Cloud Computing Infrastructure via an Improved Robust Virtualization Model. Malicious activities have continued to become an alarming issue in cloud computing. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service-provider interaction. In this work, a new virtualization model for data security monitoring was developed. Structured System Analysis and Design Methodology was adopted and design was achieved with tools such as Dataflow Diagram, Use-Case Diagram, Unified Modelling Language (UML) Diagram, and Sequence Diagram. The study utilized Five Hundred (500) datasets from robust repositories, of which 30% was used for training, while 70% was used for testing. Parameters for analyzing and evaluating the results of both systems encompassed the number of adopted algorithms, the number of adopted technologies, the number of adopted design tools, and the number of tested records. From the performance evaluation, the new system showed better performance than the existing system as it achieved an accuracy rate of 1.07% as compared to the existing system which achieved an accuracy rate of 0.48%. The newly developed model was for fraudulent data detection in cloud computing infrastructure with a special emphasis on financial fraud. This is because; financial frauds are committed against property, involving the unlawful conversion of the ownership of the property to one's personal use and benefit. In addition, the new system was further optimized with a deep neural network and logistic regression technique. This study could be beneficial to anti-corruption agencies, corporate organizations, and researchers with keen interest in the study area.

ASSESSMENT OF THE FINANCIAL RESULT OF PUBLIC-PRIVATE PARTNERSHIP PROJECT IMPLEMENTATION USING THE EXAMPLE OF A CONCESSION AGREEMENT

The article is aimed at developing a methodological approach to improving the efficiency of assessing the financial results of implementing Ukrainian and European business projects. In this context, the object of study is a specific individual partnership and cooperation project. The research has established that one of the key informational aspects of such a partnership is the assessment and forecasting of the financial result. The goal of the research is to present the methodological approach to assessing financial performance for an individual project in the most detailed form possible. The article presents an approach based on modern simulation modelling methods, systems analysis methodology, and the method of composite seasonal indices. All modelling processes were conducted using MATLAB software. MATLAB is a high-level programming language and interactive environment for numerical computation, visualization, and programming. This program is widely used for modelling and data processing in fields such as engineering, scientific research, and mathematics. The research result is presented as an approach to the mathematical modelling of assessing the financial performance of partnership projects of Ukraine with representatives of EU business.

Systematic analysis of geometric inaccuracy and its contributing factors in roboforming

Incremental sheet metal forming is a highly versatile die-less forming process for manufacturing complex sheet metal components. Robot-assisted incremental sheet forming, or roboforming, allows a wider range of tool motion, providing the capability to shape intricate components. This makes roboforming the most flexible variant of the incremental forming method. However, the serial arrangement of links and joints in a robotic manipulator results in low positional accuracy under forming loads due to insufficient structural stiffness. The stiffness of the machine frame and tool directly impacts the accuracy of the final formed profile. The impact of machine compliance on component shape in incremental sheet forming is substantial in roboforming. This work presents a methodology for systematic analysis of the factors contributing to the errors in the geometric shape of robot-based forming. Experimental and numerical methods are used to estimate the material springback, tool/tool holder deflections, and errors due to machine compliance. The CNC machine frame is relatively stiffer than the industrial robots, such that material springback is estimated based on the experimental trials on CNC for cone and variable wall angle cone profiles. Tool and tool holder deflections are estimated using finite element simulations. The analytical method using the Virtual Joint Model is used to model the joint stiffness, and consequently, the robot Cartesian stiffness is estimated to predict path deviation contributing to geometric shape errors. The proportional contribution of each factor in the overall deviation in the Roboforming is also quantified.

Operational risk estimation using system analysis methodology

Financial risks are considered today as popular research topics due to the existing practical necessity for the use of their mathematical models, estimates of possible loss in many areas of human activities, forecasting, and respective managerial decisions in financial and other spheres where capital, obligations, stocks, bonds, and other activities are circulating successfully. Financial processes today exhibit sophisticated forms of evolution in time that require the application of sophisticated modeling, risk estimating, forecasting, and decision-making/support methods, techniques, and procedures. The system analysis approach is applied to solving such problems as a unique and universal research methodology. The financial risks, specifically the operational ones in the study considered, are classified as nonlinear and nonstationary processes that require appropriate methods for analysis and a rather sophisticated analytical description to estimate and forecast possible loss. The results of operational risk analysis are achieved in the form of systemic methodology, models constructed with statistical data, regression analysis, and Bayesian techniques, and estimated loss with the models. The models and system analysis approach proposed for analyzing financial processes are suitable for practical applications, provided the users have appropriate statistical data and expert estimates.

Preservation and reproduction of cultural and historical memory in the complex of journalism functions

Addressing the phenomenon of cultural and historical memory in the context of journalism theory and professional practice is important for a number of reasons. In a theoretical sense, it is necessary to take into account the structural features of the phenomenon of cultural and historical memory and the dynamics of its development, changes and influence on the processes taking place in journalism under the influence of the formation of a new system of post-global world order. The question of the essential institutional features of journalism in the spaces of sovereign macroregions can be solved only in the search for supporting specific basic principles of the existence of the profession. One of these principles should be cultural and historical memory, which has a national origin and institutional and cultural forms of expression, to which, among others (no less, but no more important), journalism should be attributed. The methodology of system analysis is used as a fundamental principle in the work. In determining the functional structure, the approaches developed within the framework of structural and functional analysis are used. In determining the interdependence of the structure of a historical fact in journalism and the spaces of its realization, discourse analysis is used in its functional application in the form of a discursive framework. The inclusion of the issues of cultural and historical memory in the processes of professional journalistic education requires the approval of the principle of subjectivity of journalism, its institutional nature, which allows initiation and full participation in social changes. The preservation and reproduction of cultural and historical memory is present as an integral part of the complex of professional journalistic functions.The functional complex of journalism manifests itself at the strategic level as participation in the expansion of cultural space and self-determination as an active part of cultural national history. At the operational and tactical level, journalism performs the functions of socio-cultural integration, socialization and adaptation. The structural components of a historical fact in journalism (denotation, meaning and concepts) are revealed to varying degrees depending on the implementation spaces. The methodology of the spatial approach used in the study of journalism allows us to identify the natural, material, social, personal and mediated media levels of space. Denotation plays a dominant role on the natural, material and social levels, meaning plays a dominant role on the personal level, meaning plays a dominant role on the media space level, and concepts play a dominant role in audience feedback systems.

Measuring Afrocentrism: A Review of Existing Instruments

Abstract Measurement of Afrocentrism and investigation of Afrocentricity’s significance in the lives of Black Americans has gained momentum, given the current evidence suggesting that cultural factors matter in the lives of diverse populations. In particular, factors associated with African philosophical constructs may have significant relationships with improved mental health and overall well-being among African and African diaspora populations. However, the prior conceptual literature suggests that Afrocentrism is a heterogenous concept with a multitude of domains associated with its measurement. The present study was envisioned given the relative absence of studies evaluating the availability and psychometric properties of Afrocentric measures within social work. Utilizing systematic analysis methodology and PRISMA guidelines, a search for Afrocentric measures was undertaken using four key databases. Spanning the literature between 1980 and 2021, this review identified a total of seven instruments that fully met the study’s inclusion-specific criteria. In accordance with the call for continued research and practice emphasizing resilience and protective factors within the lives of Black populations, the present study provides accessible knowledge to researchers and practitioners on the currently available instruments to evaluate Afrocentrism in the lives of populations of African descent.
