Due to the closure of borders, the greatest blow fell on international air travel, but local, intercity flights also suffered due to measures to prevent the spread of COVID-19 infection. In order to find the most effective way to regulate prices for the restoration of the air travel market in the Russian Federation, airlines can use the applications of game theory, thanks to which players will be able to think through a balanced strategy of a cooperative game. The subject of the study of game theory is the mathematical analysis of situations in which the interests of several players may not coincide. At the same time, a formalized description of the described situations is presented in the form of a mathematical model called a game. When describing the game, some parameters are set, awareness of which is a key factor in the success of the agent's game. These parameters include: the number of players – the set of agents involved; the preferences of players; the area of permissible actions in the game; the awareness of players; the order (sequence) of moves, etc. The basic concepts applicable in the analysis and optimization of the air travel market are considered. Within the framework of game theory, the air travel market of the Russian segment of the world market is analyzed and an assessment of the classical situation on the market, the moves of agents and their effectiveness is given. A mathematical model of the choice of strategy by players in the classical situation on the air travel market of the Russian Federation is presented.

The current state of the construction complex of the Russian Federation cannot be considered in isolation without connection with current problems such as the lack of balance between supply and demand in the investment and construction market; difficulties in forming competitive advantages for many construction enterprises; an imbalance of the established market structure; insufficient level of organizational and managerial security and a number of others. In solving these problems, it is important to focus on the intensification of entrepreneurial efforts, the result of which should be an entrepreneurial-type model introduced into the practice of the construction complex. The purpose of the study is to develop the methodological basis of entrepreneurship in construction and the formation of its methodological tools, taking into account the specifics of the objectively existing crisis of the construction industry. The article reveals the methodological prerequisites for the formation of an entrepreneurial model of the functioning of the construction complex and the management of this model in modern conditions. The necessity of using a number of principles of innovation, competitiveness, predictive orientation, and interaction in entrepreneurship in construction is substantiated. The methods that ensure the implementation of these principles in economic practice are revealed, as well as the possibilities and prospects for using effective information support systems for entrepreneurship in construction, built taking into account the marketing paradigm and the use of monitoring tools in it, Monitoring is considered from managerial positions as a necessary condition for achieving information saturation of the decision-making process in business structures of the construction profile. The possibilities of monitoring from the perspective of the planning and management cycle implemented in construction organizations are investigated. Special attention is paid to the competitive problems, such a phenomenon characteristic of entrepreneurship in construction as "competitive diffusion"is highlighted and revealed. It is proposed that in the process of managing organizations of the type under consideration, focus on the possibilities of forming divisions and their groups that directly ensure interaction and consistency of changes in internal and external factors.

So there is an obvious signi- ficant gap in food consumption between representatives of different decile groups in terms of avai- lable resources. And although this gap has been somewhat smoothed over the past years for fruits and berries, as well as sugar and confectionery, potatoes and bread, nevertheless, for such important food products as vegetables and melons, milk and dairy products, fish, the ratio has practically not improved, and for meat and meat products the decrease is insignificant. The averaging of consumption indicators, as well as the share of food purchase expenses in consumer spen- ding, neutralizes the negative trends that develop in consumption among representatives of the first five decile groups by available resources. Taking into account these indicators, as well as the actual structure of food consumption and making additions to the Food Security Doctrine will allow the Government to create legislative bases and tools to increase the economic availability of food for a significant part of the country’s population.

The effectiveness of the development of the socio-economic system of any modern state directly depends on the rationality of the formation and the effectiveness of the implementation of the state migration policy. The purpose of the article is to analyze the trends and problems of the development of migration relations in the Russian Federation, the features of the state migration policy and the development of recommendations for its improvement. The paper analyzes the main elements of the regulatory framework in terms of regulation of the state mig- ration policy in the domestic economy. The study of the dynamics of the migration flow was carried out, and also one-factor correlation-regression analysis was used. The main approaches to the rational implementation of the migration policy of the state in relation to illegal migrants are highlighted. A statistical assessment of the dynamics of the migration flow in the Russian Fede- ration in 2010–2018 has been carried out to the level of crime. It is shown that from the point of view of maximizing the average level of profi- tability of products in the economy of the Russian Federation, the annual flow of migrants of working age should be about 200–250 thousand people. The main problems in the implementation of the state migration policy in the Russian Federation are highlighted, such as insufficient attention to the processes of intraregional migration, the lack of comprehensive programs in this area, the lack of efforts to socialize legal migrants from neighboring countries, the lack of effective measures to overcome the migration of the most qualified personnel. Recommendations were developed for improving the state migration policy in the Russian economy in terms of improving the statistical registration of migrants; implementation of a viable strategy for state management of migration processes; creation of effective mechanisms for the integration of migrants into the system of the host society; paying attention to the processes of internal migration, as well as the development of international cooperation in the field of migration policy.

This study aims to develop a simple-practical design procedure to determine the appropriate size of the turbine's outer radius for any given internal parameters according to the available flow rate through numerical calculation. The calculation is performed using python programming language by combining the existing model of Archimedes turbine, including the power calculation model, turbine flow rate capacity, and losses modeling, into a procedural design calculation to produce the appropriate value. The design procedure could be used to obtain the required and could be able to accommodate the available water flow rate optimally for any given value of each internal parameter and available flow rate. It is obtained that a higher pitch ratio would result in smaller . Moreover, the value of 0.45 would give the smallest size of the appropriate . On the other hand, the higher turbine's inclination angle would require a greater . It is also revealed that the angle of will give the turbine optimum efficiency. In addition, it is also estimated that the Archimedes turbine would be more efficient in a higher available water flow rate. The resulting design shows a good agreement with the installed Archimedes turbine based on the surveyed data at some power plants. Therefore, the proposed design can improve Archimedes Turbine's design by providing the appropriate size of according to the available flow rate without any overflow or underfilling. The design procedure could also provide a practical tool for designing Archimedes turbine.

The choice of a vehicle speed controller for a permanent magnet synchronous driven battery electric vehicle (BEV), integrated with a regenerative braking system (RBS), plays a pertinent role in how far a vehicle can travel. While many studies have implemented varied control strategies, the proportional-integral (PI) based controller is predominately studied and practically used. Generally, the performance of PI controller compared to Modeled Predictive Controller; Reference Tracking Signal Controller Based on Generated Polynomial and Reference Tracking Signal Controller Based on Controlled Polynomial in a permanent magnet synchronous motor (PMSM) driven battery electric vehicle integrated with RBS speed control based on field-oriented control mechanism is lacking. In order to address that shortcoming, this paper aims to investigate the performance of a PI controller compared to generalized predictive controllers based on the difference between a reference speed and a controlled speed of the battery electric vehicle. The performance for each controller considered was evaluated in terms of the state of charge (SOC), R^2, slip ratio, minimum error metrics, and peak speed using real-time driving scenario factoring braking, throttling, wind speed, and cruise effects for 15 s. The results show that the PI controller outperforms the other controllers on most metrics. Except for the peak SOC, slip ratio, and peak speed, the Reference Tracking Signal Controller Based on Generated Polynomial seems to be better, although with a drawback of the highest error metrics. Generally, all the controllers yielded excellent regenerative braking effects in SOC and effective control of the speed trajectory.

Published: January 2022

Science, technology, and innovation, especially technological innovation, are the basis of a competitive economy that many countries have prioritized in their economic policy. The National System of Technological Innovation (NSTI) has become the framework approved by policymakers to develop innovation capabilities in the academic and business worlds. Morocco has taken this approach by implementing several reforms, diversifying its economy, and strengthening its competitive potentials. However, scientific research and innovation, especially technological, are not contribute to the country's development. Thus, the mechanisms and instruments for financing and supporting innovation do not meet the promoters' expectations of innovative ideas and projects. In addition, the NSTI suffers from a lack of information instruments capable of effectively guiding the activities of its stakeholders. This article, based on a benchmarking and an analysis of the national context, proposes a scoreboard made up of a set of performance indicators that will serve as a tool for measuring the performance of the NSTI. This scoreboard is based on a comparative analysis of the main innovation system scoreboards at the international level and the specificities of the Moroccan context. It will serve as a performance measurement, and decision support tool for Moroccan NSTI stakeholders to effectively manage their activities, actions, and expenditures and better assess the effectiveness of their innovation promotion policy and its impact on the country's socio-economic development.

Published: January 2022

This research explores the interactive synergy between the banking sector and real economic growth in Indonesia. Demand-following and supply-leading hypotheses serve as the basic logic to understand the phenomena and help to solve the problems. Employing quarterly time-series data from 2007 to 2019 and VAR/VECM for inferential purposes, this research found a long-run relationship between liquidity, inflation rate, interest rate, and economic growth rate. Therefore, the demand-following and supply-leading hypotheses are supported in the economic development of Indonesia. Indonesia's banking sector can play the role as the engine of growth by providing the necessary funds required for lubricating the growth of the real sector, while at the same time, the growth of the real sector also pushes the development of the banking sector. In conclusion, a positive bidirectional causality between the banking sector and the real sector supports Indonesia's economic development. The key factor of Indonesia's economic stability appears to lie in its ability to maintain economic development orientation focused on a delicate balance between the growth of the supply side and the demand side.

Collaborative governance has become an important publicity concept for academics. It is designed to respond to implementation failures, high costs, and the politicization of public sector regulations. This study used a systematic literature review technic in the field of public administration in order to obtain concepts relevant to the study of collaborative governance. Data collection techniques by searching from various sources and the latest literature, both from government documents and reports from print and electronic mass media, journals, and books related to public administration and government cooperation. The results showed that the complexity of the relationship between actors in public policy gave birth to a new concept called Collaborative Governance. In short, collaborative governance is a process and structure that involves multiple parties across organizational boundaries. Collaboration describes formal, active, explicit, and collectively oriented public management and policy cooperation. Its basic values are consensus orientation in decision making (goals), collective leadership in institutions (structure), multi-way communication in human relations (interaction), and sharing of resources in action (process). These basic values become a unified whole at every stage of public policy.

Published: January 2022

This study aims to fabricate composite a scaffold using a mixture of chitosan-gelatin and limestone-extracted βTCP for better antibacterial properties. Limestone is abundantly available in nature and can provide calcium in the production of calcium phosphate (CaP) materials. However, the elemental impurities present in limestone-extracted βTCP may affect the properties of the CaP-fabricated scaffolds. βTCP powder could be used to fabricate bone scaffold using calcination and wet precipitation method. For example, the preparation of βTCP powder involved the transformation of calcium carbonate in limestone to calcium hydroxide, followed by a reaction with phosphoric acid and sintering treatment to form βTCP. In order to fabricate the scaffold, chitosan was first dissolved in acetic acid and then mixed with a gelatin-in-water solution, followed by adding βTCP powder (limestone-extracted βTCP and commercial βTCP). Then, the mixture was placed in a mold and freeze-dried. Our method improved the antibacterial activity of chitosan–gelatin–βTCP compared to the chitosan–gelatin scaffold. Limestone-extracted βTCP also exhibited higher inhibitory action against bacteria than commercial βTCP. This method's effectiveness evaluation was confirmed by the measurement of X-ray fluorescence analysis, which showed that βTCP scaffolds had more antibacterial elements than the chitosan–gelatin scaffold. These new research results contribute to enhanced antibacterial properties of the material due to elemental impurities in βTCP, especially the limestone-extracted βTCP. However, further evaluation on controlling βTCP impurities is essential for better outcomes in clinical applications.

NUMERICAL VOLTAGE RELAY ENHANCEMENT BY INTEGRATED DISCRETE WAVELET TRANSFORM
Authors: Awada Emad
Published: January 2022

In today’s advanced technology and fast past energy demands, dependency on electrical power systems have reached the peak for daily human function in all life aspects. From high-voltage to low-voltage, big machines to a very articulated chipset, voltage optimization plays an important role in work operation and energy saving of electrical devices. Therefore, the importance of voltage relay in power systems is very significant to ensure normal operation, power system efficiency, power elements protection, and load safety. However, power system failures occur all the time due to numerous reasons which may lead to voltage variation (over-voltage or under-voltage). Such a variation can disrupt the essential elements of the power system and harm consumer load. Therefore, as network distribution cannot assure the same exact voltage at all day times, the need to optimize voltage relay has been a major issue in power system reliability and protection enhancements over the past few years. This paper aims to develop a unique technique to implement and test a new wavelet-based algorithm to modern numerical voltage relay to expedite voltage fault detection and precisely distinguish harmful voltage fluctuation levels. This enhancement will advance voltage waveform analysis to detect over-voltage/under-voltage phenomena, improve relay-tripping accuracy and relay response time. That is, wavelet transform has shown the ability to advance voltage relay operation with special properties of waveform de-noising, data extraction in an adjusted window, and data decomposition. Simulation of the Discrete Wavelet transform bank filters implemented into numerical voltage relay using MATLAB/Simulink has confirmed promising results as a quick voltage error detection based on few waveform data samples, faster data compiling process, and less complexity compared to typical conventional numerical voltage relay.

The interest given to the manifestations and repercussions of learning disability (LD) is relatively recent in Morocco, not only in research but also in endorsing students and their families to contribute to the assessment of learning disability and how prevalence it, as well as the factors which may influence it, particularly factors linked to the socio-economic level, gender, genetics, and the linguistic environment. This work aims to study LD prevalence, considering the Moroccan educational system specificity. It was conducted based on three main steps: identification, screening, and diagnosis and carried out with 14,605 primary school pupils in 63 public and 16 private schools from 2012 to 2018. The identification is based on tests that seek to assess spelling in Arabic, French, along with arithmetic, to be administered collectively to the students. Screening and diagnosis are undertaken by multidisciplinary teams comprising speech therapists, neuropsychologists, psychologists, psychomotor therapists, and child psychiatrists. As a result, it was revealed that 12% of the students screened present at least one specific learning incident with specific reading disorder (dyslexia) at 11.6% of our sample. Moreover, the specific spelling disorder with a prevalence of 11.52%, and dysgraphia with a prevalence of 4.6%, while in 3% of our sample, we suspected specific disorder of arithmetic skills (dyscalculia). These disorders affect two times more boys than girls. Additionally, their rate is significantly impacted by genetic heritage and linguistic environment. However, the association between the socio-economic profile and the prevalence of learning disabilities has not been established.

Published: January 2022

This research aims to explore the potential of revenue generation and job creation from the trash. Research methodology in this study includes a semi-structured questionnaire survey, interviews with representatives of the Capital Development Authority, experts from the field and academia, scavengers, and a wide-ranging literature review. Islamabad generates approx. 2830 tons of municipal waste daily at an average rate of 1.0 kg/capita/day. Municipal solid waste contains 79% wet and inorganic recoverable material mixed with irrecoverable waste items and ultimately buried at the disposal site. Although the literacy rate in Islamabad is the highest in the country, public awareness regarding the impacts of improper waste management and benefits of appropriate waste management like revenue generation, job creation, and health does not exist. Existing waste management includes mixed waste storage at source and waste transfer stations, collection and transportation, and mixed waste dumping or burning. There is no institutional arrangement to recover above 2200 tons of recoverable materials a day from source to destination. In the informal sector, 10 percent of 79% of recyclables are recovered daily by waste pickers from streets, waste transfer stations, and waste disposal sites. Municipality in Islamabad has no policy regarding at source waste segregation, separate waste storage, collection, transportation, and restrictions on mixed waste disposal. This research would suggest measures for tapping the potential of resource generation and transformation of waste to wealth in Islamabad.

We present SiO2/GaN interfaces with a low interface state density and a high breakdown electric field. The SiO2 films were deposited by plasma-enhanced atomic layer deposition (ALD) using bis(diethylamino)silane and O2 plasma at 300 °C on n-type GaN (0001) homoepitaxial layers. An interface state density of less than 1011 cm−2 eV−1 at 0.3 eV below the conduction band edge was confirmed by the conductance method. The value is much lower than those of previously reported ALD-SiO2/GaN interfaces (1012–1013 cm−2 eV−1). A low fixed charge density at the SiO2/GaN interface of 3.7

1011 cm−2 and a high dielectric breakdown field of ~10 MV cm–1 were obtained. Moreover, the interface state density and current−voltage characteristics were further improved by post-deposition annealing at 400 °C in N2 ambient. Scanning transmission electron microscopy with energy-dispersive X-ray analysis revealed the existence of a GaO

In some hospitals the infusion is still done manually, medical staff observes ﬂuid drip directly and then controls its rate using a mechanical resistor (clamp), this method is certainly far from the level of accuracy. Infusion pump is a medical aid that has functions to control and ensure the correct dose of infusion fluid that is given to patients under treatment. The purpose of this study is to analyze the accuracy of the TCRT5000 as a drop sensor, based on readings of the infusion pump monitoring system. This module consists of a TCRT5000 drop sensor module, comparator circuit, monostable circuit, stepper motor, L298N motor driver, and ATmega328 microcontroller. The droplets are detected by the TCRT 5000 sensor, then amplified by a comparator and monostable circuit, then the flow rate and remaining volume readings are generated by the ATmega328 microcontroller. Furthermore, this data is sent to the Personal Computer (PC) via wireless HC-11. The results of the flow rate module measurement show that the highest error value is 4% at the 30 ml/hour setting, and the lowest error value is 1% at the 60 ml/hour setting. While the results of the flow rate measurement using an Infuse Device Analyzer, the highest error value is 2,2% at the 30 ml/hour setting, and the lowest error value is 0,58% at the 100 ml/hour setting. This infusion pump monitoring is designed centrally to facilitate the nurse's task in monitoring the infusion dose accurately that is given to the patient.

Change detection from time series multispectral Landsat imagery has been an active research in remote sensing for several years to monitor the ecosystem, environment, climate and so on. This study is focused on detecting the changes in surface water by the integration of fusion and image classification techniques in multi-temporal multispectral Landsat images. The panchromatic band and the multispectral band of Landsat OLI and TM images respectively, were fused using undecimated wavelet transform to get the pan-sharpened image. Then classification techniques like Maximum Likelihood, Support Vector Machine, Artificial Neural Network and Random Forest were employed for extracting the water pixels and changed pixels. The performances of these classification techniques were analyzed based on metrics such as overall error, commission error, precision, recall, overall accuracy, kappa coefficients and the results show that the application of random forest classifier on pansharpened image outperforms in extracting the water pixels and also in highlighting the changes with maximum accuracy.

Road irregularities, e.g. potholes or bulges, will cause discomfort, vehicle damages or even accidents, if not being carefully handled by drivers. For driving safety and comfort, especially in highly automated vehicles, there is a need for accurate and efficient way to estimate the road condition ahead in advance. Existing direct sensing based methods are difficult to give detailed irregularity information, while current response based approaches require either too many measurements or accurate system parameters to guarantee estimation performances. Therefore, using the information of preceding vehicle responses, a Kalman filter based algorithm to estimate severe road irregularities is proposed. The single degree of freedom vertical dynamics model is reorganized to reduce the measurement requirements of the Kalman filter. To cope with the limited information of the preceding vehicle, the model parameters are approximated according to suspension design theories. Simulation and field data validation shows that the estimation algorithm is effective and robust on different vehicles.
