Aims: The purpose of this work is to formulate the theoretically justified information approach to analyze different methods of measuring Hubble’s constant, and to verify their advantages and disadvantages. Place and Duration of Study: Mechanical & Refrigeration Consultation Expert, between June 2019 and November 2019. Methodology: Due to the fact that any measurement model contains a certain amount of information about the studied object, comparative uncertainty is introduced, by which the least achievable relative uncertainty when measuring the Hubble constant is calculated. Results: The experimental results of measuring the Hubble constant presented in the scientific literature are analyzed using the proposed information approach. Conclusion: The information approach can be considered as an additional look at the Hubble constant tension. Most likely, this will help to understand the current situation and identify possible specific ways to solve it.

Aims: To analyze the results of measurements of the Boltzmann, gravitational and Planck constants using a theoretically sound information approach in comparison with the CODATA technique. Place and Duration of Study: Beer-Sheba, between January 2019 and May 2019. Methodology: Using the concepts of information theory, the amount of information contained in the measurement model of a physical constant is calculated. This allows us to find the value of the comparative uncertainty proposed by Brillouin, and the achievable value of the relative uncertainty, taking into account the basic SI values used on each test bench when measuring physical constants. Results: An unsolved question was to find the amount of information contained in the model of the measurement of a physical constant, which can be converted to the value of the achievable absolute uncertainty. This value now has an exact analytical formula. It is notoriously difficult to study the consistency of the measurement results of physical constants, but the proposed mathematical tool, developed using the concepts of information theory, allow us to simplify the analysis completely. Conclusion: The information method leads to an intuitive and logically justified calculation of the relative uncertainty, which is compatible with the current practice of CODATA. This allows you to identify the threshold discrepancy between the model and the object under study. Proof of this is the calculation of the achievable value of the relative uncertainty when measuring the Boltzmann, gravitational and Planck constants. The proposed information-oriented method for calculating the relative uncertainty in measuring physical constants represents a new tool when formulating a modernized SI.

Design Result

BACKGROUND most serious games and other game-based tools are designed as digital games or escape games. They are designed for learning or sometimes in the field of medicine as an aid to care. However, they can also be seen as an aid to research, in our case, to evaluate the advantages and disadvantages of imaging techniques for cancer detection. OBJECTIVE we present a case study of action research on the design of a serious board game intended to consider the advantages and weaknesses of a diagnostic method in a different ways. The goal was to better understand the principles of designing a tool using game or play. METHODS we explicitly implemented another process than gamification to develop a structure reminiscent of the game to highlight the strengths and weaknesses of different imaging techniques from the point of view of the respondents (in this case specialists not directly involved in the project). Based on this feedback and the scientific literature on this subject, we detail the main categories of games and games developed for serious use in order to understand their differences. Concerning the cancer research part to which game contributes, our method is based on questions asked to experts and practitioners of this specialty. RESULTS an expert point of view translation tool in the form of a game has been realized to apprehend a research in a different way. CONCLUSIONS we show with the help of a diagram, some possible design paths leading to this type of design result including two hidden dimensions to consider (the awareness of the game or play by the "player" and his role as a contributor or recipient).

The article is devoted to the problem of the banks’ participation in improving the efficiency of the organization of cash circulation, which does not lose its relevance in the modern economy. In the current situation, despite the growth in the volume and share of non-cash payments, the demand for cash is characterized by stability. The article focuses on the features, advantages and disadvantages of the reducing cash circulation process. It is noted that the primary impact on cash circulation is made by settlements made by individuals. In this regard, the study focuses on the fundamental changes in this direction that are taking place in the banking sector. This is, first of all, the reduction of cash withdrawals from plastic cards and the growth of non-cash payments with their use, the lack of growth of the card market; increase in electronic terminals and reduce the number of ATMs installed. At the same time, it is emphasized that one of the main areas that determine both the liquidity and profitability of the bank is the regulation of cash balances. With the number of banks operating in the economy shrinking, the struggle for customers is becoming more acute. The satisfaction of the latter with the quality of the bank’s services, including in terms of settlement liquidity, should be considered as one of the primary factors that ensure the effectiveness of a significant number of banking operations. In this context, special attention is paid to the specifics of the bank’s actions to optimize cash flows, which requires the use of specialized automatic systems that allow processing data on cash balances and turnover to form forecasts that optimize the collection schedule and reduce ATM downtime due to lack of funds

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

Introduction. Despite the notable and rapid progress in the development of medical 3D printing in recent years, not much is known about the use of this technology in obstetrics and gynecology.The purpose of our review of scientific literature was to determine the current level of 3D printing development, discuss the closest and long term prospects for using this technology in obstetrics and gynecology, and analyze its potential advantages and disadvantages.Materials and methods. We searched for scientific literature. 378 papers passed a three-step screening, as a result of which 42 sources were selected for the final scientific review.Results and discussion. The main areas in which dimensional printing can be used in this area of medicine is the creation of simulation models and training for students, the creation of anatomical models for preoperative preparation, the surgical instruments, the creation of new dosage drug forms (including transvaginal ones), and bioprinting of organs and tissues.Conclusion. The presented literary review allows us to conclude that 3D printing the obstetrics and gynecology is a current rapidly developing direction. The organization of 3D modeling and printing laboratories can significantly increase the efficiency of teaching students and residents. In addition, obstetricians-gynecologists and surgeons should be informed about the possibility of 3D printing surgical instruments according to an individual design. It can inspire them to implement their own ideas and develop domestic innovative developments. Three-dimensional printing of dosage forms and bioprostheses requires more complex technological solutions, and is not yet used in clinical practice. However, given the enormous prospects for these areas, various grants should be envisaged for their development in Russia

Abstract The satellite attitude determination approach based on the Extended Kalman Filter (EKF) has been widely used in many real applications. However, the accuracy of this method largely depends on the fitness of measurement model. We aim to analyse the influence of measurement errors to the accuracy of EKF based attitude determination approach in this paper. The measurement errors, which are divided into structural error and nonstructural error by their influences, are analysed in principle. In the setting of the combination of star sensors and gyros, according to the property of innovation, we employ the technique of correlation test to analyse the influences of different kinds of measurement errors. Experimental results demonstrate the effectiveness of our previous analysis.
