This paper presents a proposed design and analysis of a three-phase squirrel cage induction motor when changing of internal characteristic design for the three-phase induction motor. Two situations have been applied to enhancing the performance of the three-phase induction motor. The first situation has been implemented by changing the magnetic flux density (MFD) via the build of the six-phase for the same induction motor. The second situation has been implemented by changing core materials of the rotor part of the induction motor, like aluminum (AL) and cast iron (CI). The finite element method (FEM) has been used to analyze the rotor part, also to obtain the representation and simulation of the realty cylindrical rotor part of motor. The frequency domain (FD) analysis using to obtain the results within the environment of the COMSOL multiphysics 5.5 version.

Purpose Communicating appreciation to employees has been shown to be an important factor in contributing to employee engagement and making workplaces more effective. Research has shown that employees differ in how they desire to be shown appreciation. The purpose of this paper is to examine how working remotely (vs onsite), the experience of the COVID-19 pandemic and employees’ age group impacted the ways employees want to be shown appreciation at work. Design/methodology/approach Using the five Languages of Appreciation as a framework (Chapman and White, 2019), over 200,000 individuals’ results from the Motivating By Appreciation Inventory were compared across various groups. The dependent variable: (Primary Language of Appreciation) was examined in light of three independent variables: work setting (onsite vs remote), timeframe (pre-COVID-19 vs during COVID-19) and age range of the employee. Findings Preferences for how to be shown appreciation were quite stable across work setting, timeframe and age range, suggesting that one’s preferred ways of being shown appreciation is largely an internal characteristic that is only mildly influenced by external factors. Minor trends were found when comparing various age groups and remote vs onsite employees. Originality/value Understanding the impact of the COVID-19 pandemic on employees’ desires for appreciation is critical for organizational leaders. With vast numbers of new remote employees in the workforce, understanding how they are similar to and vary from onsite employees is paramount for addressing the needs of all team members. This study provides valuable information on both topics, as well as differences across age groups.

The power quality assessment provides a reference for power quality management and control of microgrid operation. In terms of reflecting the correlation of power quality indexes and the dynamic changes of microgrid operating conditions, the traditional power quality assessment methods need to be improved. A power quality comprehensive evaluation based on CRITIC and dynamic coefficient is proposed in this paper. In this method, the objective weight of power quality indicators in single node is determined by using the intensity of conflict and contrast firstly. For the node weight calculation, the dynamic coefficient is proposed to reflect the different influence degree of node with different connected load. The proposed method in this paper can reflect both the internal characteristic of data sequence and the relationship between different data sequences. In addition, it also can reflect the dynamic changes of microgrid. Finally, an example is used to verify the feasibility of the proposed method.

The article examines the epistemological status of the phenomenon of social trust. The research purpose is to explicate the concept of trust in connection with the fundamental transformation of socio-historical practice and social knowledge. The priority methodological task is to study the problem within the framework of the system methodology evolution and consider the parameters of trust in the intervals of non-classical and post-non-classical systems analysis. The study is based on a philosophical-scientific paradigm approach. Epistemological situations of autonomous and conventional application of different paradigms are modeled in the study of the phenomenon of social trust. In non-classical systems analysis, social trust is an internal characteristic of a society-system in the mode of its correct functioning. Social trust is one of the social order mechanisms. Social trust is also associated with subjective trust, ordering the interaction of subjects. Intersubjective interactions entail the legitimation of the social order. The transformation of social trust in the modern world is associated with trends in the reduction of the role of normativity, the fragmentation of socio-historical existence. There appears augmented reality, which contains to a certain extent the elements of pseudo-being. Subjective social trust can no longer support holistic meanings. In a situation of change in epistemological attitudes to determine the specifics of social trust, a systems analysis of weakly and highly non-equilibrium states of the intersystem environment is promising. Social order formulas are still inadequate for modeling intersystem environmental states (relations between states, blocs, unions, etc.). Within the framework of the post-non-classical systemic methodology, social trust refers to the signs of social holism. Social trust contributes to the emergence of stable intersystem conditions, the formation of a regulatory environment, which becomes an acting unit. Social trust in all philosophical-scientific paradigms is indicative of the rationality of social-historical existence.

A significant role of the banking system in ensuring the functioning of the entire economy, by means of organizing the movement of borrowed capital between individual industries and the implementation of financial needs is achieved only if this system, and therefore its constituent elements, are stable. In this regard, the stability of the banking system should be considered as a fundamental internal characteristic, which ensures the existence and stable development of the Bank in a market economy under the influence of external and internal factors. In 2020, commercial banks were faced with the impact of the coronavirus pandemic on the Russian economy and the banking system in particular. At the same time, the current situation of banks ' functioning is characterized not only by the presence of a corona crisis, but also by the internal development of the system itself, which, following the uberization of the world economy, dictates to commercial banks the need to develop and implement financial technologies and form ecosystems. In these conditions, the need for commercial banks in financial resources increases, which is reflected in the increasing role of profit in the Bank's activities and development. This article focuses on the impact of the coronavirus pandemic on the banking system of the Russian Federation and the economy as a whole, and also identifies the features of profit formation and the specifics of the functioning of commercial banks in the coronavirus crisis period.

Studies of parental supervision often fail to consider the broader ecology in which youth are developing. In this paper, moderation and mediation analysis were utilized to examine parental supervision along with the ecological asset of supportive relationships, which have been identified as especially powerful assets, in a sample of 289 adolescents from the United States. These factors are considered in relation to positive indicators that have specifically been associated with youth thriving: self-control and future aspiration. Results of a mediation analysis suggest that family support mediates the relationship between parental supervision and both indicators. Therefore, parents should ensure they are demonstrating support during attempts to supervise youth. In addition, supportive relationships with adults at school further promote the development of an important internal characteristic: self-control. Including aspects of the broader ecology in studies of youth development is essential to uncovering the role external assets play in promoting positive outcomes for adolescents.

We study mechanisms leading to wealth condensation. As a natural starting point, our model adopts a neoclassical point of view, i.e., we completely ignore work, production, and productive relations, and focus only on bilateral link between two randomly selected agents. We propose a simple matching process with deterministic trading rules and random selection of trading agents. Furthermore, we also neglect the internal characteristic of traded goods and analyse only the relative wealth changes of each agent. This is often the case in financial markets, where a traded good is money itself in various forms and various maturities. We assume that agents trade according to the rules of utility and decision theories. Agents possess incomplete knowledge about market conditions, but the market is in equilibrium. We show that these relatively frugal assumptions naturally lead to a wealth condensation. Moreover, we discuss the role of wealth redistribution in such a model.
