Smart Contract as a New Way to Conclude a Contract
Authors: Mayorov A. A.
Published: July 2022

The development of modern technologies has led to the creation of a new way to conclude agreements through automated systems — smart contracts, the emergence of which was largely due to the development of distributed ledger technology (Blockchain). The advantage of the system of “smart contracts” is the ability to make transactions directly with counterparties, without resorting to the services of banks, payment system operators and other transaction operators, which, in turn, reduces costs. Smart contracts can also be used during remote electronic voting, allowing you to solve problems related to security, reliability of data and their protection. Many states have managed to assess the advantages of this technology, having decided to implement it in the digital economy. But before implementing the achievements of scientific and technological progress, it is necessary to understand their technical and legal nature in order to form proper legislation regulating their application. Within the framework of this work, the technical and legal features of smart contract technology are considered in comparison with the traditional form of concluding contracts, and it is also proposed to use it in economic turnover within a special platform.

Authors: Nosov Sergei V. , Рeregudov Nicholay Е.
Published: July 2022

BACKGROUND: At considering the issues of crawler tractors interaction with soil the determining factor is the time-varying impact of loads on the soil layer, its stressed and strained state, which, in turn, directly depends on its stress-strain properties. The properties assessment should be carried out with a rheological approach, which allows to explain many phenomena and processes and to develop new high technologies in terms of the criterion of minimizing the impact on the soil.
AIMS: Studying the compacting ability of a crawler tractor in a configuration in various machine-tractor units, obtaining a curve for the effect of the traction load on the tractor hook, tractor speed and tractor mass redistribution over the lower track wheels on changes in soil compaction due to developing deformations, the coefficient of running resistance and skidding of the crawler-mounted mover.
METHODS: The evoluation method for compaction impact of crawler-mounted mover on the soil layer was developed on the base of the previously constructed a general mathematical model for determining ways of reducing the compacting impact of crawler-mounted movers on the bearing surface, computer calculation programmes and the carried out assessment for the deformation development and changes of soil compaction under the crawler track.
RESULTS: There are presented the simulation results of the process with an assessment of the developing dependences of the crawler tractor rut depth and its sliding on the travelling speed and on the displacement of the center of pressure at different loads on the hook, that obtained with the developed metod of analysis and the well-known theory of hereditary creep of elastic-visco-plastic materials. At the same time, the development of vertical and shear deformations of the soil layer in the area of lower track wheels impact is separately analyzed.
The analysis of the constructed dependencies allows to identify a number of patterns for changes of compacting effect indicators of a crawler tractor on the soil with an assessment of the influence of the main design and technological parameters on them. It is established that taking into account the rheological characteristics of the soil layer and its state parameters permit significantly improve the accuracy of calculations for vertical and shear deformations of the soil layer and its final compaction after successive passes of the crawler lower track wheels. At the same time, the desired indicators behavior is ambiguously at passes of various lower track wheels.
CONCLUSION: The conducted studies contribute to the optimal selection of parts for various machine-tractor units based on a specific crawler tractor, which perform the appropriate technological operations in certain conditions of work at specific parameters of the soil state.

Published: July 2022

BACKGROUND: Often, parts of the working bodies of machines operating in abrasive environments have a cantilever mount. Due to wear, their dimensions are lost, specified by the technical conditions, and destruction occurs. The resource of these products is determined by the allowable bending stresses, taking into account the intensity of their wear. The existing theoretical methods for predicting the operating time of a part to its limiting state when solving problems do not take into account the criteria of strength and wear in the complex.
AIMS: The aim consists in obtaining a mathematical expression that determines the resource of the part when it is worn, taking into account the allowable stresses.
METHODS: The disclosure of the goal was carried out by solving the problem of predicting the resource of a cantilever-fixed using the classical course of the resistance of materials, ele-ments of the theory of elasticity and the basics of tribotechnics.
RESULTS: As a result of mathematical research and based on practical knowledge, a formula was obtained for determining the resource of a part, which takes into account the dimensions of the part, the magnitude of the allowable stresses, the coefficient regulating the resistance of the material to wear, the pressure on the working surface, the pressure at the pinch point and the pres-sure at the free end timber. The conditions determined by two inequalities are established under which the part will be operable.
CONCLUSION: Mathematical expressions have been obtained that make it possible to predict and the conditions for the performance of cantilever-fixed parts in the process of their wear ac-cording to allowable stresses have been determined.
The system of training of pedagogical and scientific personnel during the leadership of the department of general and military epidemiology by academician V.D. Belyakov (to the 100th anniversary of the birth of academician V.D. Belyakov)
Authors: Belov Alexander  B. , Ishkildin Mars I. , Lantsov Evgeniy V.
Published: July 2022

On the basis of generalization and analysis of published scientific works and memoirs of academician V.D. Belyakovs contemporaries, the main stages of his scientific and pedagogical activity as head of the Department of General and Military Epidemiology of the Military Medical Academy named after S.M. Kirov are considered. It is shown how, under the leadership of the activities of the department staff by Vitaly Dmitrievich Belyakov, the training of the teaching staff was set, ensuring continuous professional development and the ascent of employees along the hierarchical service and scientific ladder. The system of training its own personnel worked correctly and effectively within the department, and some such systems continue to work even now, preserving the best traditions laid down in the era of V.D. Belyakov to maintain the reputation of the department created for decades. Academician Vitaly Dmitrievich Belyakov, an outstanding military epidemiologist, scientist, and teacher, Major General of the medical service, who consistently headed the epidemiology departments of two leading educational medical institutions of the country in St. Petersburg and Moscow, had a great influence on the development of not only military epidemiology but also domestic medicine in general. Having developed, with his students at the S.M. Kirov Military Medical Academy, the theory of internal regulation of parasitic systems, recognized as the biological foundation of the epidemiology of infectious diseases, he reformatted the previous theory of the epidemic process into the paradigm of population pathology of biomedical sciences. He was one of the first to consider epidemiology as a general medical diagnostic and preventive discipline, actively introducing epidemiological research methods into clinical medicine and public health, as well as into medical education at all levels at the I.M. Sechenov Moscow Medical Academy. He can be considered the founder of the methodology of epidemiological diagnostics, who extended it to population non-infectious pathology, and the founder of the original and effective concept of epidemiological surveillance. In addition, the system of training and management of pedagogical and scientific personnel created by V.D. Belyakov deserves attention.
A Robust Statistical Framework to Properly Test the Spatiotemporal Variations of the b-Value: An Application to the Geothermal and Volcanic Zones of the Nevado del Ruiz Volcano
Authors: Aguilera Bustos Joaquin Pablo , Taroni Matteo , Adam Ludmila
Published: July 2022

Estimating and testing b-value changes spatially and temporally is challenging due to the lack of constraints in the methodology. Commonly, only the direct information of earthquake catalogs is used to test the b-value variation hypotheses, and the same dataset is used both to define anomalous spatiotemporal areas and to perform the test. Here we propose a rigorous statistical framework to estimate and test b-value spatial and temporal differences. This framework is then applied to earthquake magnitude data from the Nevado del Ruiz Volcano (NRV) in Colombia acquired between 2000 and 2018. Our b-value spatial analysis is constrained by geological and geophysical data of the study area, and the timing of volcanic eruption periods is used for temporal variations of b-values. High b-values with a low level of uncertainty occur within a geothermal zone at the NRV and over a zone of magmatic activity. The b-value spatial test is validated using a novel weighted likelihood method that clearly defines these high b-value anomalies. In terms of temporal variations, contrary to observations at other volcanoes, high b-values are obtained outside eruption time windows, whereas during eruption periods the b-value decreases. Our framework sets a foundation for distinguishing spatial and temporal b-value behavior in other active seismic zones.
Switching Control Design for Aircraft Actuator Failures
Authors:   , Bayram Mevlut , Chang Bor-Chin
Published: July 2022

Loss-of-control (LOC) recovery of impaired aircraft actuator failures is a challenging control problem due to the loss of control service authority, uncertain persistent disturbances, sudden shift of flight trim, flight mode confusion, and rapid deterioration of LOC condition. In this study, the NASA GTM (Generic Transport Model) aircraft is employed to demonstrate the proposed multivariable H2 servomechanism control solution that can stabilize the impaired aircraft at the desired flight mode constrained by the actuator failure and performing precision regulation/tracking for altitude, flight path, sideslip, and yaw angle rate - providing the stability and maneuverability required to keep the aircraft flying and allow for a safe landing. The actuator failures considered in this work include a jammed elevator control and a loss of engine thrust for multi-engine aircraft. For the GTM aircraft LOC recovery control application of a jammed elevator case, the challenging issue in predesigning a fixed mitigating controller is that the jam position is unknown until it actually occurs. By modeling the unknown jammed position as an uncertain disturbance with the help of servomechanism regulator theory, we are able to employ only two linear H2/servomechanism controllers to cover all elevator jams that may occur in the recoverable range. In the case of engine failures, one may believe that an aircraft with multiple engines will have a better survival rate than a single-engine aircraft; however, the statistical data show the opposite. Although the pilots are trained to fly aircraft experiencing engine failure, the manual mitigation procedure is complicated, especially for asymmetrical engine failures. Our proposed automated control system is capable of utilizing the diversified redundant features of the rudder and ailerons to work with the remaining engines to maintain a stable flight until a safe landing can be achieved.
Student Reflections on an Internship in Educational Leadership
Authors:   , Benson Amy , Kozak Michael G
Published: July 2022

Researchers and legislators are seeking ways to improve educational leadership programs to better prepare individuals to lead today's schools. Researchers have often focused these efforts on an objectivist research paradigm, examining program outcomes and perspectives of current leaders. As such, few studies have engaged students in conversations about their internship experience. The purpose of the present study is to examine graduate students' perceptions of their internship experience and preparation in the field upon completing a year-long internship grounded in Experiential Learning Theory and the Professional Standards for Educational Leaders. The study additionally examined whether gender differences existed in these perceptions. It is the theory of the current study that the use of this subjective research is a critical step in strengthening educational leadership programs. The overarching research question that guided this study was, Do graduate students believe their internships provided them with the experiences necessary to be future educational leaders? The researcher posed the following research questions to further guide this study: (a) To what extent do graduate student interns believe their internships provided them with the experiential learning necessary to be educational leaders? (b) To what extent do graduate student interns feel prepared to carry out leadership skills related to the Professional Standards for Educational Leaders upon completing their internship? (c) What experiences do graduate student interns identify as the most and least beneficial in the internship? (d) Do students' perceptions of their internships and feelings of preparation differ by gender? Data were collected and research questions were analyzed using surveys and individual interviews at a single university. Four results emerged across quantitative and qualitative results: (a) students believed their internships provided them with the experiential learning necessary to be educational leaders, (b) students expressed confidence in their leadership performances, while also discussing a desire for additional practice due to the COVID pandemic, (c) students placed a high value on relationships and experiential learning, while also identifying the COVID pandemic as the least beneficial experience, (d) gender differences persist in the field of educational leadership. Results of this study support prior literature on educational leadership, while offering new data on students' views of their internship experience.
The Impact of Lab Delivery Method on Student Achievement, Transfer of Learning, and Self-Perception in an Anatomy and Physiology Course
Authors:   , Bianco Laura Jean , Betts Kristen S
Published: July 2022

Distance education has become increasingly popular among college students over the last two decades and institutions have responded to this demand by offering more online and hybrid courses. These courses provide many benefits to students, including increased flexibility and accessibility, which contribute to its growing popularity. However, science, technology, engineering, and math (STEM) disciplines have been slower to create online courses, likely due to the laboratory component that most STEM courses contain, which has traditionally been completed in a face-to-face setting. Many faculty, administrators, and national organizations have indicated that virtual labs cannot serve as an effective replacement for in-person labs. The purpose of this quantitative, causal comparative study was to examine the impact that lab delivery methods have on the achievement of learning outcomes, transfer of learning, and self-perception as it relates to persistence among higher education students in an anatomy and physiology lab course. A total of 99 students participated in this study; 53 of these students completed an in-person lab, while the other 46 students completed a virtual lab during an anatomy and physiology course. Pre- and post-tests were used to assess student achievement and learning transfer, while pre- and post-surveys were used to assess changes in students' self-perceptions related to persistence in college and persistence in the sciences. The results indicated that students who completed the in-person lab displayed higher achievement than the students who completed the virtual lab; however, there was no significant difference in the transfer of learning between the two groups. Additionally, the students who completed the in-person lab experienced a significant increase in their self-perceptions related to persistence in the sciences, while the virtual lab students did not. Neither method of lab delivery had a significant impact on self-perception regarding college persistence. Based on these results, the recommendations are that virtual labs should be offered in conjunction with, rather than in place of, in-person labs and that lab experiences should be interactive and engaging, regardless of the delivery method.
Analysis and Design of Control Systems for Impaired Aircraft
Authors:   , Catpinar Sevket Fatih , Chang Bor-Chin
Published: July 2022

Designing an automatic control system for an aircraft with a jammed elevator during flight is a complex challenge since it is impossible to predict the exact jam position before it occurs. Once a jam failure has occurred, there is often a short time frame to respond, and the situation may deteriorate rapidly as time goes by. An aircraft with an elevator jam will lose more than 50% of its ability to maneuver its flight in pitch direction. Furthermore, the aerodynamic force exerted upon the jammed elevator surface will cause persistent disturbance against the flight. These two factors will make the control of the impaired aircraft very difficult or even impossible. The nominal flight equilibrium, which is associated with the nominal flight condition, will disappear if the elevator moves away its equilibrium and jam elsewhere. The system may become unstable and uncontrollable quickly if no appropriate action is taken in time. The flight of the impaired aircraft is unpredictable, which can be a nose down, tail spin, heading to a crash. The most challenging issues are that the location of the elevator jam is uncertain and the mitigation time window is limited. Without knowing the elevator jam position, it seems impossible to know what flight equilibrium the aircraft would flight and thus there is no aircraft flight dynamics model available for the control system designer before the event occurs. The control system design and implementation may be carried out on board right after the jam occurs; however, it will waste much of the rescuable time window in accurately estimating the jam position, finding a safe flight equilibrium, assembling the flight dynamics model at the equilibrium, and designing/implementing a failure mitigation controller. The solution we propose is a single predesigned fixed controller for the equilibrium of a safe flight after an elevator jam occurs. The design does not require the exact knowledge of the jam position. It only requires the time of jam to switch to the new predesigned mitigation controller. It seems to good to be true, but it becomes possible due to the following three reasons: (1) The regulator control theory can be employed to address the uncertain persistent disturbance on the jammed elevator control surface, (2) The diversified redundancy provided by the engine thrust control can be employed to compensate the loss control authority of the elevator; and most importantly, (3) The geometry of the equilibrium manifold can be employed to determine a feasible safe flight equilibrium without knowing the elevator jam position.
The View from Below: Rob Ford and Perceptions of Canada on U.S. Late Night Comedy
Authors: Friedman May
Published: July 2022

This analysis aims to review the means by which an imagined Canadianness is described through the responses of American comedians to late Toronto mayor Rob Ford on comedy shows which aired between May 2013 and May 2014. The Rob Ford story, as taken up in late night U.S. comedy, both maintains and transgresses stereotypes about Canada and Canadians. Likewise, an examination of the constructed Ford (and the constructed Canada which simultaneously emerges) in late night comedy focuses on appropriate behaviours and expectations, especially with respect to the governance of body and mind.

Students, especially high school students, will always be faced with several choices, both related to personal, social, study, career, and talent lives. They often have difficulty making decisions in determining which options to choose. One of them is the difficulty in understanding oneself related to his talent and the talent plans that will be selected for his future. Difficulties in making decisions when choosing talents can be avoided if students have a sufficient amount of information about matters relating to the world of their talents. Therefore they need to get development in their talent. This research uses the literature study method. The results of this study indicate that full Islamic guidance and counseling is needed as an effort to obtain an adequate understanding of various conditions and characteristics of himself, as a 'servant of Allah' who chooses nature (potential) both about talents, interests, ideas, various strengths and weaknesses. that is in him so as not to be wrong in developing his talents in accordance with Islamic guidance (Al-Qur'an and Hadith).

Published: July 2022

Due to the rising trend in 2-Dimensional material, graphene has gained a lot of interest in the recent past. Graphene is the 2D carbon allotrope with high strength and improved mechanical, chemical, and electrical properties. Despite being excellent properties among other types of carbon allotropes but still, graphene use is limited because of its costly synthesis technique. In this research, a cheap and effective method is adapted for the preparation of graphene from graphite powder. The graphite powder is thermally treated to prepare the exfoliated graphite then exfoliated graphite is milled to produce the 2D graphene sheets. The synthesized graphene is characterized by X-Ray Diffractometry (XRD) and Scanning Electron Microscope (SEM). The XRD results show that graphene is successfully synthesized, and SEM results show that graphene is 2D which can be used in various applications. This research provides a direction for the synthesis of graphene from graphite powder on an industrial scale.

Published: July 2022

In this paper, an implementation of a feedback linearisation-based on SVM control of a multifunctional unified power quality conditioner (UPQC) combined with a photovoltaic generator (PVG) using STM32F429I-DISC DSP board has been presented. Further, The PVG-UPQC is acting as a universal conditioner for power quality enhancement and renewable energy integration simultaneously with harmonics reduction in both grid voltage and current. Furthermore, the system can also compensate reactive power in presence of nonlinear loads. The presented system is made up of a shunt active power filter which acts as a current harmonics compensator in addition to a series filter that compensates voltage harmonics and fluctuations such as voltage sag/swell. In order to enhancing the PVG-UPQC performances, a nonlinear feedback linearisation control technique combined with SVM controller is applied. The performance of the suggested control scheme is validated by extensive PIL co-simulation technique. The obtained results prove the high performances and reliability of the presented system in the case of nonlinear load variations as well as eliminating voltage and current harmonics. These results accomplish the superiority and effectiveness of those obtained by a compared to a conventional PI controller.

Published: July 2022

The increase use of polluting equipment, especially in the field of power electronics, has caused appearance of harmonics and deterioration in the supplied current wave quality. For this reason, several harmonic pollution control methods have been developed, and the use of the active filtering presents the most efficient and appropriate solution. This work concerns improving energy quality of an electrical network by using an active parallel filter. To achieve this objective, three essential steps were pursued: identification of the harmonic currents, insertion and control of an active parallel filter, and checking effectiveness of the adopted filtering strategy by comparing the total harmonic distortion (THD) values before and after filtering. The various obtained results prove capacity of the inserted active filter to decontaminate harmonic pollution and consequently improve the energy quality.

Published: July 2022

Multilevel inverters are a novel type of dc–ac converter designed for medium and high voltage and power applications. Cascaded multilevel inverters are the most common inverters used in renewable energy applications. Despite the numerous advantages, the presence of extra circuit components in the design causes reliability concerns with these inverters. Researchers have faced a significant difficulty in constructing inverters with improved dependability by lowering total harmonic distortion (THD). This paper proposes a concept of Grid connected PV system with multilevel inverter topology. The PV system is implemented by using mathematical analysis and MPPT based dc-dc boost converter is used to improve the performance of PV system. In this paper, perturb and observe MPPT technique is implemented. For obtaining better harmonic distortions and proper synchronization with grid a multi-level inverter is implemented. This paper proposes a novel multilevel inverter topology for renewable energy operations which produces 31 and 51 level output voltages. The conventional topology is formed with 10 IGBT switches. A closed loop controller with sinusoidal pulse width modulation technique is implemented to generate gate signals required for 31-Level converter. The 51-Level converter is modelled with 8-IGBT switches and 4-diodes, also space vector and sinusoidal pulse width modulation techniques are used to generate the gate signals for switches. This proposed system is tested and verified in MATLAB and a comparative analysis made between sinusoidal and space vector modulation in 51-Level topology.

The smart factory is a concept to express the ultimate goal of digitization in manufacturing. The most common definition of a smart factory is a highly digital store floor that collects and shares data on a continuous basis through connected devices and production systems. the proposed system focuses on reducing the delay by using hybrid computing, cloud, and edge servers. The purpose of this study is to investigate Real-time requirements using the Selection Algorithm. The factory is represented by a group of sensors that send data to three servers. (Two are edge servers with the same copies of data and rules, and the third is the cloud). When the sensor's reading reaches the edge servers, scheduling time an selection algorithm is implemented through which a single edge server receives data selecting the least delay the highest priority. Alternatively, if there is any problem or malfunction affects one of the edge servers, the second can complete its work without the need to stop the factory. In turn, the delay is reduced, and the factory performance is improved. When the delay time is reduced, the response time is improved and the service quality will be enhanced.

Sin embargo, aun cuando el niño no sea aún una persona, en virtud de la legislación vigente, el niño por nacer tiene derechos que deben ser salvaguardados por el Estado y su falta de protección debe dar lugar a procesos de reparación o responsabilidades internacionales. Este trabajo explora las condiciones en las que el feto puede ser reconocido como víctima y los mecanismos de reparación que eventualmente serían los más adecuados, basados en la jurisprudencia y otros precedentes.

The ASEAN region is emerging as a dynamically developing region, and trade between Vietnam and ASEAN countries has continuously improved over the years. This study investigates the determinants of Vietnam’s exports to ASEAN countries from 1997 to 2020. The paper also examines the differences in the directions of the impact in different groups of exported products. Using pooled OLS and panel data methods, the results demonstrate that Vietnam’s exports increased as its GDP per capita and importing countries’ GDP per capita increased. In contrast, transportation costs proxied by geographic distance were found to have a negative impact on Vietnam’s exports. The results assert the positive relationship between exports and real bilateral exchange rate. The ASEAN Trade in Goods Agreement (ATIGA) was found to have no statistically significant influence on Vietnam’s exports. These results are vital for trade policy formulation to promote Vietnam’s exports to ASEAN countries. Vietnam should promote trade with countries sharing a border to take advantage of transportation costs and reduce potential risks in goods movement. In addition, it is necessary to minimize the effects of fluctuations in the exchange rate in order to further promote Vietnam's exports in the future.

Obesity/its comorbidities occasionally exist alone, but actually, this is a dynamic network of cross morbidities that are often regarded as separable entities. Obesity is nowadays viewed as an escalating risk factor for iron deficiency, and various theories have been proposed since then explaining their relation. We aimed to determine the relationship of increased body mass index (BMI) with adiponectin, leptin, and iron profile in a sample of middle-aged and older adults with and without iron deficiency anemia. An observational study was performed among 90 participants classified into three groups. Group І included healthy subjects with normal BMI; as a control. Group II included subjects with increased BMI, and group III included subjects with increased BMI and iron deficiency anemia. After overnight fasting, fasting blood glucose, triglycerides, total cholesterol, iron, total iron-binding capacity, complete blood count, serum leptin, and adiponectin were measured. There were significantly higher mean values of BMI among those with anemia, higher mean values of serum leptin, and significantly lower mean values of adiponectin. A significant positive correlation of serum leptin with BMI and a significant negative correlation of serum leptin with iron in Group III were reported. The adiponectin/leptin ratio of (0.8) was correlated with iron and homeostatic model assessment in Group III, and a ratio of (1.1) was significantly correlated with BMI and hemoglobin level in Group II. This could suggest that interventions aimed at increasing the adiponectin/leptin ratio may help in resolving anemia among obese populations by increasing their serum iron and hemoglobin.

Advances in medicine and medical technology have presented new moral challenges in terms of the management of extremely preterm infants and newborns with severe anomalies and advanced asphyxia. The aim of the present study was to examine the attitudes of health care providers and parents regarding decisions about the treatment of these neonates. The attitude of the Shia clerics is assessed in this study as well. In this qualitative content analysis research, data were collected through semi-structured interviews and focus group discussions (FGDs) with 98 participants, including physicians, nurse practitioners, medical ethicists, Shia clerics, and parents. Purposive sampling was employed by selecting those members of the community whom we thought would provide us with the best information and were also eager to participate. Data collection continued until data saturation was reached. Data analysis was carried out using conventional content analysis. Analysis of the data resulted in the extraction of 332 codes along with the following four categories: the necessity for preparation of a national guideline for the management of neonates with poor prognosis, the establishment of hospital neonatal-management committees, decision-making regarding the limits of viability, and parental support. This study affirms that the responsibility in terms of decision-making for neonates with poor prognosis lies upon hospital neonatal-management committees based on approved national guidelines such that decisions are made according to the aforementioned guidelines, Islamic moral codes, and scope of services available in medical units. This study dismisses individual decision-making and underlines the responsibility of a hospital neonatal-management committee in making decisions based on approved guidelines that conform to the regulations of national law and Islamic moral codes that determine the continuation or withdrawal of medical care and treatment of infants with a poor prognosis while bearing in mind that regulations, hospital facilities, resources, and other conditions differ in various hospitals within the country and with developed countries.
