Factors Influencing User Perception and Adoption of E-Government Services

The objective of this study is to investigate and determine factors influencing user perception and acceptance of electronic government services in the context of technological advancements. The research focuses on classifying the main features of e-administrative systems with an emphasis on user satisfaction by integrating both traditional and modern data analysis techniques. Structural Equation Modelling (SEM), machine learning (ML) techniques, and multi-criteria decision-making (MCDM) methods have been applied to survey data to uncover the interdependencies between variables from the perspective of online users. The developed models discover and explain the underlying relationships in user attitudes towards e-government services. As the perception of customer satisfaction is subjective and dynamic, stakeholders should conduct regular measurements and data analysis to ensure continuous improvement of e-public services.

Life, its definition, origin, evolution, and four-dimensional hierarchical structure

The main unique features of biological systems are reviewed, and four necessary and sufficient attributes of life are formulated, based on the ideas of Ervin Bauer. The possibility of the occurrence of each of these attributes during the origin of life is analyzed. As a result, different scenarios for the origin of life are presented, with their pros and cons. Next, the mainstream of biological evolution is discussed, considering it as a special case of general complexification, and structuredness is defined as a quantitative measure of structural complexity. By introducing the concepts of post-dissipative structure and ratcheting process based on “frozen” patterns, their role in the generation of biological structures underlying biological evolution is demonstrated. Furthermore, it is proposed that all living things can be divided into micro- (unicellular) and macro- (multicellular) creatures, which differ from each other even more radically than the difference between prokaryotes and unicellular eukaryotes. Then the fifth, sufficient, but not necessary attribute of life, hierarchicality, is formulated, which is fully applicable only to macrolife. It is also shown that living organisms are primarily chemodynamic rather than thermodynamic systems, and three basic laws of biochemodynamics are formulated. Finally, fifteen basic features of living beings, grouped into four basic blocks, are summarized.

The ground state, localization, and chiral edge dynamics of a three-legged bosonic magnetic ladder

Three-legged bosonic/fermionic magnetic ladder, reproducing the main features of magnetic lattice systems, is an ideal model to study the edge-bulk coupling and chiral edge dynamics, which are a hallmark of quantum Hall physics. Here, the ground state transition, localization, and chiral edge (bulk) states of an interacting three-legged bosonic magnetic ladder are studied analytically and numerically. When the system is in a quasi-steady state, using variational analysis, the threshold for the transition from zero momentum state to plane wave state is obtained. The energy spectrum, the ground state diagram, the chiral current of the system are presented, and the chiral current reversal at the state transition point is observed. Furthermore, the localization and its stability in the system are discussed, and rich localized phenomena (diffusion, breather, soliton, and self-trapping) are predicted. Stable soliton/breather prefers to form an edge state, while the self-trapping is favorite to form a bulk state, i.e. localized edge and bulk states are obtained. Particularly, for the unstable soliton in the ground state or metastable state, different kinds of chiral edge/bulk state and edge-bulk coupling are observed. The stability of the localized states, the edge-bulk coupling characteristics, and the chirality of the system depend on the energy band structure of the system. Additionally, a controllable transition between localized edge state and bulk state is realized by quenching the soliton state. We proposed a theoretical evidence to design and manipulate edge-bulk coupling and different kinds of localized/chiral edge (bulk) states in three-legged bosonic magnetic ladder.

Iterative Neuro-Fuzzy Hammerstein Model Based Model Predictive Control for Wind Turbines

Strong nonlinearity and high volatility are the main features of wind turbine systems. Under the conditions of random wind speed changes, how to quickly control the wind turbine output power within the rated range is a major challenge for wind power system control. This paper proposed an iterative neuro-fuzzy Hammerstein model based model predictive control for wind turbines. Initially, an iterative neuro-fuzzy Hammerstein model is used to characterize the feature of wind turbines. The nonlinear static component's aerodynamic property is estimated using neuro-fuzzy networks, and the linear dynamic component is identified using the AutoRegressive with Exogenous Input (ARX) model. Following this, a generalized wind turbine controlled object with linear properties is constructed by computing the inverse of the nonlinear part, converting the wind turbine's nonlinear control challenge into a linear model control problem. This is done by the unique structure of the Hammerstein model, which allows the linear and nonlinear parts to be separated. Furthermore, a globally convergent parameter learning method is proposed and applied to identify the nonlinear parameters of the Hammerstein model. Eventually, the implementation of the Hammerstein-MPC is compared with the MPC, fuzzy MPC, and PI controllers by FAST simulation. These results demonstrate the superiority of the control effect based on the generalized wind turbine system.

COMPARATIVE ANALYSIS OF CHARACTERISTICS OF CADASTRAL SYSTEMS OF EUROPEAN UNION COUNTRIES

A modern cadastral system should include a legal, technical and economic component. The legal component determines information about owners and users taking into account the historical aspect of registration of property rights, the technical component should include data on the location of the land plot, its quantitative and qualitative indicators, and the economic component, in turn, forms an idea of the ways of using this land plot and its value. There are various types of land cadastral systems, which differ in their structure and functionality, so the study of their main characteristics is an urgent issue today. The purpose of this article is to determine the main characteristics and features of cadastral systems with the aim of improving the State Land Cadastre of Ukraine. Modern cadastral systems of the world are organized mainly by the land registration component. According to this feature, two main systems of securing rights to land ownership or real estate are distinguished: "Agreement system" and "Title system". The difference between the two concepts is related to the cultural development and judicial system of the country and is whether only the transaction is registered (deal system) or the title itself is registered and protected (title system). А comparative analysis of the developed and reliable European cadastral systems of Austria, Germany, Switzerland and France was performed. It was established that all considered cadastral systems have the same characteristics, such as: completeness and accuracy of geodata – presented in the form of a detailed cadastral map; accessibility and ease of use – access to cadastral systems is free and available to citizens; security level – modern technologies are used to protect data, including encryption and authentication of users; regularity of updates – usually once a year, and distinctive features, namely: variety of functions that they solve; various data collection systems are used; different level of integration with other systems. Keywords: cadastral system, state land cadastre, geospatial data, land plot, geoportal.

Emergence in Artificial Life.

Even when concepts similar to emergence have been used since antiquity, we lack an agreed definition. However, emergence has been identified as one of the main features of complex systems. Most would agree on the statement "life is complex." Thus understanding emergence and complexity should benefit the study of living systems. It can be said that life emerges from the interactions of complex molecules. But how useful is this to understanding living systems? Artificial Life (ALife) has been developed in recent decades to study life using a synthetic approach: Build it to understand it. ALife systems are not so complex, be they soft (simulations), hard (robots), or wet(protocells). Thus, we can aim at first understanding emergence in ALife, to then use this knowledge in biology. I argue that to understand emergence and life, it becomes useful to use information as a framework. In a general sense, I define emergence as information that is not present at one scale but present at another. This perspective avoids problems of studying emergence from a materialist framework and can also be useful in the study of self-organization and complexity.

Customer Attitude toward Digital Wallet Services

The goal of this study is to examine and identify the factors influencing customer attitude toward and intention to use digital wallets (electronic wallets, e-wallets) during and after the COVID-19 pandemic. A total of 257 correctly fulfilled questionnaires from an online survey were summarized. The main features of e-wallet payment systems were classified with a focus on consumer satisfaction via the integration of classic and modern data analysis methods. Structural Equation Modeling (SEM) was preferred to reveal the dependencies between the variables from e-wallets users’ perspective. The designed model can discover and explain the underlying relationships that determine the e-wallets’ adoption mechanism. The obtained results lead to specific recommendations to stakeholders in the value chain of payment processing. Financial regulatory authorities could employ the presented results in planning the development of payment systems. E-commerce marketers could utilize the proposed methodology to assess, compare and select an alternative way for order payment. E-wallet service providers could establish a reliable multi-criteria system for the evaluation of digital wallet adoption. Being aware of the most important components of e-wallets value, managers can more effectively run and control payment platforms, enhance customer experience, and thus improve the company’s competitiveness. As the perceived value of customer satisfaction is subjective and dynamic, measurements and data analysis should be conducted periodically.

Mechanisms Regulating Energy Homeostasis in Plant Cells and Their Potential to Inspire Electrical Microgrids Models.

In this paper, the main features of systems that are required to flexibly modulate energy states of plant cells in response to environmental fluctuations are surveyed and summarized. Plant cells possess multiple sources (chloroplasts and mitochondria) to produce energy that is consumed to drive many processes, as well as mechanisms that adequately provide energy to the processes with high priority depending on the conditions. Such energy-providing systems are tightly linked to sensors that monitor the status of the environment and inside the cell. In addition, plants possess the ability to efficiently store and transport energy both at the cell level and at a higher level. Furthermore, these systems can finely tune the various mechanisms of energy homeostasis in plant cells in response to the changes in environment, also assuring the plant survival under adverse environmental conditions. Electrical power systems are prone to the effects of environmental changes as well; furthermore, they are required to be increasingly resilient to the threats of extreme natural events caused, for example, by climate changes, outages, and/or external deliberate attacks. Starting from this consideration, similarities between energy-related processes in plant cells and electrical power grids are identified, and the potential of mechanisms regulating energy homeostasis in plant cells to inspire the definition of new models of flexible and resilient electrical power grids, particularly microgrids, is delineated. The main contribution of this review is surveying energy regulatory mechanisms in detail as a reference and helping readers to find useful information for their work in this research field.

Financial and legal regulation of electronic money circulation

This article provides a comprehensive overview of the history of e-money and the current state of the market. Electronic money is regulated by special legislation in the Republic of Kazakhstan. Article gives  proposals and conclusions that contribute to the effective consideration of the problems encountered in practice on various theoretical and practical bases. Easy and fast payment systems that pay for paid services over the Internet are well thought out. It is obvious that electronic payment systems, which are carried out in a simple way, are more flexible for sellers and consumers, as well as Internet users, because they are more flexible. That's why "electronic money" was invented. Plastic cards are an identifiable quick tool that goes into a bank account. However, we cannot classify e-money as a type of plastic card, because: plastic cards have a role only as a means of access to a bank account or as a carrier of electronic money. In essence, plastic cards are not money. Electronic money is a means of payment on a plastic medium used in electronic circuits. This means that money is a means of carrying out payment transactions by transmitting electronic signals without the involvement of paper carriers. The main features of payment systems using electronic money - the equivalent value of money paid in advance by the issuer (issuer - the provider of payment services with the right to issue and reimburse electronic money), stored on card microprocessors, computer hard drives and other devices digitally controlled by its owner. We see that it can be used as a tool without direct participation in banking operations. Keywords: electronic money, payment system, mobile banking, sms-banking, mobile operator payment, electronic wallet, online payment in the Republic of Kazakhstan, electronic money issuer in Kazakhstan, electronic money system.

Building-Integrated Photovoltaic (BIPV) products and systems: A review of energy-related behavior

This paper reviews the main energy-related features of building-integrated photovoltaic (BIPV) modules and systems, to serve as a reference for researchers, architects, BIPV manufacturers, and BIPV designers. The energy-related behavior of BIPV modules includes thermal, solar, optical and electrical aspects. Suitable standardization to evaluate heat transfer and solar heat gain by BIPV modules still need to be developed further since BIPV elements behave differently to the building elements they substitute. The optical properties of BIPV modules, such as light transmittance or color rendering, also play a role in the search for a good balance between energy saving, electricity generation, aesthetics and visual comfort. However, architecturally adapted BIPV design may affect the electrical performance also, by reducing the efficiency of BIPV modules and systems compared to standard photovoltaic (PV) ones. This is not the sole challenge for the electrical designers, as the special operating conditions of BIPV systems such as non-homogeneous irradiance complicate the electrical design and the forecasting of BIPV performance. The aim of this review is to present the current state of knowledge of the aspects mentioned above, to promote continued progress in BIPV and to inform suitable standardization efforts.

Time-delay-locked dynamic mode decomposition for extracting flow patterns of compressor in experiment

Dynamic mode decomposition (DMD) is widely used in extracting the main features of high-dimensional nonlinear systems in computational fluid dynamics. However, it cannot be directly applied to real compressors due to the limitations of data acquisition over the entire flow field. In order to overcome this limitation, our paper proposes a time-delay-locked DMD algorithm. It combines the idea of phase locking, Hankel time-delay method, and DMD method. Based on it, the flow patterns are successfully extracted and the unsteady flow phenomena including rotating stall and rotating instability are explained as modal waves. Multi-peak spectrum nearly 1/2 BPF observed under off-design RI conditions is explained. In addition, multi-scale of rotating stall is analyzed and shock wave is captured.

Lotka-Volterra versus May-Leonard formulations of the spatial stochastic rock-paper-scissors model: The missing link.

The rock-paper-scissors (RPS) model successfully reproduces some of the main features of simple cyclic predator-prey systems with interspecific competition observed in nature. Still, lattice-based simulations of the spatial stochastic RPS model are known to give rise to significantly different results, depending on whether the three-state Lotka-Volterra or the four-state May-Leonard formulation is employed. This is true independently of the values of the model parameters and of the use of either a von Neumann or a Moore neighborhood. In this paper, we introduce a simple modification to the standard spatial stochastic RPS model in which the range of the search of the nearest neighbor may be extended up to a maximum Euclidean radius R. We show that, with this adjustment, the Lotka-Volterra and May-Leonard formulations can be designed to produce similar results, both in terms of dynamical properties and spatial features, by means of an appropriate parameter choice. In particular, we show that this modified spatial stochastic RPS model naturally leads to the emergence of spiral patterns in both its three- and four-state formulations.
