Authors: Korenyuk Petro , Chernyavskyy Mark
Published: June 2021

The article identifies the interrelation between organizational changes and the organizational development of enterprises that affect the formation of the system for substantiation of management decisions. It has been proven that within the confines of cognitive modeling there exists a possibility for determining management decisions in respect of implementation of management of organizational development of the enterprise with account for primary processes that occur both within the enterprise and in its external environment. It is determined that the baseline for the cognitive approach is comprised by the complex system model in the form of a cognitive map. It is emphasized that the indeterminacy of a reference model is manifested in the insufficient completeness of information related to parameters of broadness of the range of services rendered by enterprises, quality of their provision as well as the socio-economic situation in the regions of the country and their areas of influence. Indeterminacies in modeling the anticipated state of enterprises emerge in the process of searching for an optimum combination of organizational measures for the most efficient solution to problems pertaining to the development of the sphere. Factors of the cognitive model of management of the organizational development of enterprises are investigated within the scope of the paper. The article studies the impact of 13 factors of internal business environment upon the formation of the system of management of organizational development of enterprises on the basis of impulse modeling. It is proven that within the system of management of organizational development of enterprises the target factor is the «Level of management decision making» while other factors under scrutiny are the guided ones. Employing namely the dynamic analysis allows to determine stabilizing and destabilizing factors of impact upon the organizational development of enterprises. The range of variation for indicator factors of management of organizational development of enterprises in the «min-max» system are identified within the framework of the article. Prospects of further research consist in the studies of the formation of alternative scenarios for management of organizational development of enterprises depending on the impact of diverse factors on the basis of cognitive modeling and determining the corresponding tools of organizational changes.

Published: June 2021

Сучасні підходи до моделювання процесів в активній зоні, насамперед у перехідних та аварійних режимах, з метою проведення аналізу безпеки ядерних реакторів, вимагають використання сполучених теплогідравлічних та нейтронно-фізичних розрахункових програм. Однією з таких програм є комп’ютерний код TRACE з модулем тривимірної кінетики PARCS.

Розробка розрахункової моделі водо-водяного енергетичного реактора (ВВЕР-1000) для коду PARCS та подальша її валідація є складною багатоступеневою задачею, починаючи з підготовки бібліотеки нейтронно-фізичних констант, від якості якої залежить точність моделювання фізичних процесів в активній зоні, та закінчуючи проведенням валідаційних розрахунків та їх аналізом.

У цій статті стисло описано всі стадії розробки розрахункової моделі та результати валідаційних розрахунків – наведено підходи до підготовки бібліотеки нейтронно-фізичних констант, необхідної для розрахунків кодом PARCS, коротко описані розроблені нейтронно-фізична та теплогідравлічна моделі активної зони та наведені результати валідаційних розрахунків реалізованої моделі ВВЕР‑1000 для коду PARCS.

Метою проведених розрахунків є валідація розробленої розрахункової моделі активної зони ВВЕР‑1000 для комп’ютерного коду PARCS, а саме підтвердження того, що розроблена модель придатна для застосування у рамках проведення нейтронно-фізичних розрахунків стаціонарних станів та перехідних і аварійних режимів експлуатації реакторної установки ВВЕР‑1000. Валідація розрахункової моделі полягала в порівняльному аналізі отриманих результатів розрахунку основних нейтронно-фізичних характеристик із результатами, отриманими під час експериментальних досліджень чотирьох реальних паливних завантажень енергоблока № 2 Відокремленого підрозділу «Хмельницька атомна електростанція», та з отриманими результатами розрахунку з використанням коду DYN3D для аналогічних розрахункових станів. Розрахункові моделювання охоплювали стани на мінімально контрольованому рівні та номінальному рівні потужності, а також за різних положень робочої групи органів регулювання системи управління і захисту, а також перехідний (динамічний) процес зі спрацюванням прискореного розвантаження блока для третього паливного завантаження енергоблока № 2 Відокремленого підрозділу «Хмельницька атомна електростанція».

Точна та оперативна інформація про експлуатаційні характеристики ядерного реактора, джерелом якої є система внутрішньореакторного контролю, дає змогу оцінити рівень безпеки у процесі експлуатації енергоблоків АЕС. На цей час в Україні завершується розробка власного математичного забезпечення для системи внутрішньореакторного контролю ВВЕР-1000, що є однією із важливих умов реалізації програми диверсифікації ядерного палива. Науковий колектив ПрАТ «СНВО «Імпульс» розробив математичне забезпечення національного розрахункового комплексу на основі гібридного методу рішення системи двогрупових дифузійних рівнянь, що об’єднує в собі метод кінцевих різниць та нодальний метод. У статті наведено методологію рішення системи двогрупових дифузійних рівнянь гібридним методом для гексагональної геометрії. Наведено порівняння розрахунку, виконаного розробленим кодом на основі гібридного методу, з даними, зазначеними в бенчмарку AER-FCM101. Результати порівняння з бенчмарком свідчать про високу точність розробленого програмного забезпечення для розрахунку стаціонарного стану активної зони. Показано, що можна досягти відхилення від результатів бенчмарка приблизно 2-3 pcm для ефективного коефіцієнта розмноження. Найкраще узгодження з бенчмарком по енерговиділенню (для KV максимальне відхилення – 1,52 %, середньо-квадратичне відхилення – 0,531 %) досягається за 54 нодами на одну тепловидільну збірку в плані та за 24 однаковими за висотою шарами в аксіальному напрямку. Гібридний метод, для тієї самої розрахункової сітки, дає вищу точність ніж метод кінцевих різниць, особливо в областях з високою неоднорідністю розподілу нейтронів.
Soret and Diffusion Coefficients Measurement for Binary and Ternary Mixtures on Board the International Space Station Using SODI Apparatus
Authors: Ahadi Amirhossein
Published: June 2021

Thermodiffusion or Soret effect is a heat and mass transfer phenomenon in a non-isothermal liquid and gas mixtures. This phenomenon is more pronounced in oil fields, usually due to the porous environment. A precise and better understanding of the thermodiffusion phenomena in multi-component mixtures results in a more accurate modeling of oil reservoirs. Accordingly, the main objective of this study is to investigate the thermodiffusion phenomenon in the multicomponent mixtures. In order to achieve this objective, two series of thermodiffusion experiments conducted on board the International Space Station (ISS) using the SODI (Selectable Optical Diagnostics Instrument) facility were analyzed. The first series of experiments aimed to study the effects of the forced vibration on the Soret phenomena. The experimental mixture was water and isopropanol with different compositions subjected to various temperature gradients normal to the vibrations. Results revealed maximum separation for the case with the minimum vibration and the lower temperature gradient; however, a linear relationship between Gershuni number and maximum separation was not found. On the other hand, the second series of experiment was aimed to the measurement of the diffusion coefficients of selected ternary mixtures. Mixtures of tetrahydronaphthalene-isobutylbenzene-dodecane at five different compositions were hosted in the DSC (Diffusion and Soret Coefficient) cell array. Thus, the Soret diffusion coefficients and the molecular diffusion coefficients of the mentioned hydrocarbon mixture at five different compositions have been reported. To process the results of these experiments an advance image processing technique was developed and implemented in an application with GUI (Graphical User Interface) for the Mach-Zehnder interferometer (MZI). Then, the application of the windowed Fourier transformation (WFT) to analyze the heat and mass transfer problem using the MZI setup is proposed. Results show that the WFT noticeably improves the measurement of concentration. This improvement is more evident for the ternary. It was shown that about 10% underestimation of the Soret coefficient would be resulted; if an accurate determination of the thermal time for the MZI is not used. The reliability and the repeatability of the MZI apparatus on board ISS to study thermodiffusion for binary and ternary mixtures were shown.

Published: June 2021

The study examined the influence of the personal characteristics of extension agents in Edo State Agricultural Development Programme (ESADP) on their job performance. A well - structured questionnaire was used to collect information from fifty-three respondents, spread across the ADP blocks in the three agricultural zones in the study area. Data were analyzed using descriptive statistics and chi-square.  The findings of the study showed that majority of the respondents were male (66.0%) and married (94.3%). Majority (83%) had OND/NCE certificate and were relatively young (average age = 40 years) and experienced as extension agents (average = 14 years). The job performance of majority of the extension workers was rated high (58.5%). Also, Chi- square result showed that there was no significant association between the personal characteristics of the extension agents and their job performance. The study therefore suggests the need to examine organizational factors as crucial incentives needed to enhance the job performance of the workers in the study area

Pyrene (C16H10) is an organic semiconductor which has wide applications in the field of organic electronics suitable for the development of organic light emitting diodes (OLED) and organic photovoltaic cells (OPV). In this work, Density Functional Theory (DFT) using Becke’s three and Lee Yang Parr (B3LYP) functional with basis set 6-311++G(d, p) implemented in Gaussian 03 package was  used to compute total energy, bond parameters, HOMO-LUMO energy gap, electron affinity, ionization potential, chemical reactivity descriptors, dipole moment, isotropic polarizability (α), anisotropy of polarizability ( Δ∝) total first order hyper-polarizability () and second order hyperpolarizability (). The molecules used are pyrene, 1-chloropyrene and 4-chloropyrene  in gas phase and in five different solvents: benzene, chloroform, acetone, DMSO and water. The results obtained show that solvents and chlorination actually influenced the properties of the molecules. The isolated pyrene in acetone has the largest value of HOMO-LUMO energy gap of and is a bit closer to a previously reported experimental value of  and hence is the most stable. Thus, the pyrene molecule has more kinetic stability and can be described as low reactive molecule. The calculated dipole moments are in the order of 4-chloropyrene (1.7645 D) < 1-chloropyrene (1.9663 D) in gas phase. The anisotropy of polarizability ( for pyrene and its derivatives were found to increase with increasing polarity of the solvents.  In a nutshell, the molecules will be promising for organic optoelectronic devices based on their computed properties as reported by this work.

A deterministic mathematical model of cholera infection incorporating health education campaign, vaccination of susceptible humans, treatment of infected human and water sanitation is developed. It is shown that the solution of the model uniquely exist, it is positive and bounded in a certain region. The disease-free equilibrium (DFE) state of the model was determined and used to compute the basic reproduction number  as a threshold for effective disease management. The result from stability analysis for the disease-free equilibrium state (DFEs) shows that it is locally as well as globally asymptotically stable whenever the basic reproduction number  is less than unity (). The results obtained from the sensitivity index of   show that the control parameters of public health education campaign, vaccination of susceptible individuals, treatment of infected humans and water sanitation are crucial parameters to cholera management. Numerical simulations show that, expanded and improved vaccination among other interventions is crucial in decreasing cholera burden. Furthermore, from the numerical simulations and results it is recommended that a combination of mass and consistent public health education campaigns, expanded vaccination coverage, prompt treatment of infected individuals, with water sanitation, is vital to public health strategies in eradicating cholera infection and deaths in the shortest possible time

Authors: Gürbüz Ramazan , Çalık Muammer
Published: June 2021

Since contemporary learning theories, strategies and models offer the interdisciplinary approach, educators need new pedagogical alternative ways to attain it in practicum. For this reason, the current research aimed to illustrate how to intertwine mathematical modeling with an environmental issue that recruits waste management (e.g., reuse-recycle-reduce) to live an environmentally friendly lifestyle. Through a case study research, 6 seventh-grade students (3 females and 3 males; aged 13-14) voluntarily participated in the research. The researchers videotaped and analyzed all interactive learning processes to elicit the students’ environmental dialogues. The results indicated that the interdisciplinary mathematical modeling afforded the students to acquire the targeted environmental concepts/issues and somewhat supported their arguments. Since the current research illustrates an alternative pedagogy to integrate science/environmental education into mathematics, it may be used to facilitate dissemination and applicability of the STEM education.

The article considers the components of investment management processes to reproduce the resource potential of agricultural enterprises, which include investment strategy, principles and methods of management, objects and subjects of management.
It is generalized that expanded reproduction is a constantly regenerative process of conducting production activities on an increased scale, which in agricultural enterprises is carried out under the influence of bioclimatic, economic, social factors that determine its specificity and characterize the use of resources and production and economic relations.
It is argued that the resource potential of an agricultural enterprise should be considered as a set of labor, material, intangible, financial, innovative and managerial resources of a certain quantity and quality, which will help achieve development goals taking into account natural, climatic and economic conditions.
The constituent elements of management of investment processes of reproduction of resource potential of agricultural enterprises are substantiated, which include: investment strategy, management goals, management factors, principles and methods of management on factors, management resources.
The set of principles as a basis of tools of development and realization of investment strategy is systematized and supplemented by general economic principles and principles of planning, principles of coherence of investment strategy. .It is offered at development of investment strategy to supplement the allocated principles with the principle of a priority of a choice of directions of investment activity that will allow to allocate projects of the priority realization which correspond to the strategic purposes of the enterprise.
It is argued that the specifics of investment activities of agricultural enterprises are due to the following factors: natural and climatic conditions, organizational and economic mechanism of management, investment climate (regulatory regulation of investment), and features of agriculture. It is highlighted that the main task of investment activity as an element of the reproductive system of the enterprise is to create sufficient resources at the initial stage - on the terms of simple reproduction, at the second stage - on the terms of expanded reproduction.

Authors: Bachynskyi R.
Published: June 2021

International experience of stimulation of green initiatives in agriculture is summarized in this article, directions of its implementation in national practice are determined. The article proves that insufficient development of green initiatives in agriculture is a result of effect of limiting barriers having economic and economic nature, and low level of development of incentive tools to stimulate agricultural producers. The arguments are given to understand the importance of foreign practice of incentives for agrarian producers to introduce green initiatives in agricultural industry, and to determine directions of its implementation in Ukrainian practice.
The article demonstrates that green initiatives in agriculture at the level of commercial entity are possible only in case of targeted, joint and coordinated activities of the state, society, united territorial communities (UTC) and agricultural enterprises. It is proposed to examine green initiatives in agriculture as a systemic process of organization of nature protection activities of the enterprise basing on coordinated actions of agrarian producers, the structures of state power and administration, UTC, connected with use of the complex of tools and measures to stimulate environmentally safe activities.
It is summarized that legal acts and regulations governing nature protection activities in EU states include the following incentive tools to stimulate green initiatives: regulatory, informative and economic tools. Economic tools to motivate the enterprises to adopt environmentally friendly activities are determined: they include ecologic taxes, ecologic quotas, ecologic funds, subsidies and taxbenefits, deposit refund systems, etc.
The components of information support of manufacturers are described: they include information about applicable laws and regulations for nature protection, statistic data, researches, reviews and analytical reports, strategic programs developed, information about the options of financing, environmentally-friendly solutions for enterprises. The reasons are given to support creation of information system to stimulate green initiatives implemented in agrarian activities in national practice.

Published: June 2021

The fish assemblages of the Galicia Bank and the closest continental slope (northwest of Spain) were analysed using otter trawls to improve our understanding of how environmental drivers structure seamount fish communities in the deep sea. The effect of environmental drivers on these assemblages was studied using multivariate techniques together with the variation in α and β diversity across assemblages. Fish fauna in the study area was distributed in 5 different assemblages generated by the action of 3 main drivers: depth, distance to the coast and presence of cold-water corals. The observed differences in species composition among assemblages were mostly explained by species turnover across a depth gradient. The seamount summit and the continental slope showed important differences despite sharing similar depths, mainly because several species requiring shallow juvenile habitats were absent from the summit. These absences were observed in both summit assemblages inside and outside the cold-water coral reef. Our results show that in isolated seamounts with relatively deep summits, the lack of connectivity with shallower areas limits the presence of certain species, probably due to the impossibility for these species to migrate directly from shallow to deeper seabed areas. These species are replaced by species with preferences for deeper habitats, providing the fish assemblages located at the top of the summit with a deeper profile than observed in fish assemblages of the continental slope.
A DESCRIPTIVE EXAMINATION OF THE IMPACT OF CANADIAN MORTGAGE STRESS TEST IN LENDING, BORROWING AND AFFORDABILITY
Authors: Sardar Tariq , Sardar Tariq
Published: June 2021

A number of Canadians need to borrow money
from lenders to purchase residential properties through
mortgage route. The history of existing mortgage system in
Canada is more than 100 years old. Canada Mortgage and
Housing Corporation (CMHC) was created in 1946 to
regulate the industry. There were 4.3 million homes under
mortgage debt until 2017 and 0.5 million homes had Home
Equity Line of Credit. In 2018, the Banking Regulatory
Authority Canada imposed a New Stress Test on mortgage
borrowers and changed the criteria of loan approval.
Previously, the lenders do not need to test the affordability
of those borrowers who put a down payment of 20% or
above but now the lenders must need to test the borrowing
power of all applicants under higher interest rates imposed
by the government rather than the actual rate of interest
being offered by lenders to borrowers. The descriptive
study examined the influence of stress test in lending
process, borrowing capacity of home buyers and loan
affordability to pay off the debt under agreed terms. The
study explains the current situation of delinquency and
possible default after analyzing 370 samples collected from
the city of Brampton. The research findings also
highlighted the testing criteria, payment frequencies and actual amount to pay off the debt after purchasing.

of a set of monomers namely acrylamide, maleic anhydride,
styrene, and octadecyl methacrylate and further grafted to
nano silica for improving the flow properties and thereby
decrease the temperature of pour point value of the NorthEast Indian waxy based crude oil. Moreover, to emphasize
and understand the central effects of different concentrations
of synthesized nanocomposite pour point depressants on the
pour point of waxy crude oil, several important experiments
were undergone and later its results were compared with the
commercial pour point depressant. In addition, the
rheological props of the sample crude were also analyzed
with and without additives. The results shows that the
synthesized nanocomposite has more effectively reduced the
viscosity as well as pour point of the sample to desired value
when compared to that of the commercially used pour point
depressant.
AIRFOIL SHAPED STRUTS FOR VERTICAL AXIS WIND TURBINE
Authors: Jain Samyak , Singh Gautam , Yadav Varun , Bisht Rahul
Published: June 2021

Currently, many countries are racing
towards switching to clean energy resource (1). Among the
options available Solar and Wind are two viable options
that are economically feasible. Each day a new
development is helping in bringing down the cost of energy
extracted from these sources.
With currently available technologies, solar energy is
almost as expensive as the energy generated from burning
coal, whereas wind energy is still slightly expensive (2).
However, wind energy could be made cheaper by the use
of a vertical axis wind turbine (3).
However, structure is a major factor that is holding
back the development of VAWTs with better efficiency (4).
The efficiency of a VAWT depends upon its aspect ratio.
Aspect Ratio is the ratio of the height of the blade to the
diameter of the turbine. The lower the aspect ratio, the
higher the efficiency (5). However, decreasing the AR
would mean either increasing the diameter of the turbine
or the height of the blade. In either case, the bending
moment would increase on the struts, that connect the
blades to the shaft.
In this paper we propose, struts with airfoil cross-section.
This is because, the lift generated by airfoil struts acts as
additional support for the blade, thus increasing our
ability to work at lower aspect ratios.

The use of a physical controller such as a mouse,
a keyboard for human computer interaction hinders the
natural interface since the user and computer have a high
barrier. Our aim is to create an application that controls
some basic features of computers using hand gestures
through an integrated webcam to resolve this issue. A Hand
Gesture Recognition system detects gestures and translates
them into specific actions to make our work easier. This can
be pursued using OpenCV to capture the gestures which
will be interfaced using Django, React.Js and Electron. An
algorithm named YOLO is used to train the system
accordingly. The gestures will get saved inside the DBMS.
The main result expected is that the user will be able to
control the basic functions of the system using his/her hand
gestures and hence providing them utmost comfort.

mostly for drying agrarian food items. Thusly, in this
paper, an endeavor has been taken, to sum up, the
past and momentum research in the field of nuclear
power stockpiling innovation in materials as
reasonable and dormant warmth in sunlight-based
dryers for drying agrarian food items. With the
capacity unit, rural food materials can be dried in the
late night, while late-night drying was unrealistic
with an ordinary sun-based dryer. So that, a sunpowered dryer with a capacity unit is valuable for
people and just as for energy preservation. As of late,
analysts considered the warmth move upgrade of the
thermal energy stockpiling with PCMs because most
stage change materials have low warm conductivity,
which causes quite a while for the charging and
releasing interaction. Normally, the plan of idle
warmth nuclear power stockpiling will lessen the
expense and the volume of cooling frameworks and
organizations.

outbreak of Covid-19, a large number of educational
institutions around the world have been shut down in
connection with face-to-face classes. Because of this virus,
damage to education has increased; As we face the
unpredictable future found around the world, we need to
provide our society as a whole with flexible and vibrant
education systems. In this paper, a meta-analysis method is
adopted and the related literature. Relevant literature was
conducted to entrap the core of further study during the
period. Findings show that universities around the world
are increasingly moving toward online education or elearning. The study also shows that ICT is an important
component of integrated learning, in addition to a variety
of resources such as staff willingness, trust, student
reachability, and stimulus. This paper suggests that faculty
members should use and use technology and technical
clothing to enhance learning during these unexpected
times. This suggests that online and distance learning is a

DIGITAL CONTROL OF A CLOSED LOOP BUCK CONVERTER
Authors: Prarthana Doshi
Published: June 2021

The primary focus for the R&D in this area
so far has been to figure out the best approach for
evaluating and designing the DC-DC converter and
perhaps the most appropriate control technique is being
applied in different DC-DC converter circuits. Depending
on power handling capacity as well as high-frequency
switching, certain switching devices are chosen. This paper
discusses the deployment of the digital PID controllers in
the DC-DC converters. In an attempt to get a quicker
response, voltage mode control has been used. Digital
controllers started replacing traditional analog controllers
more and more. Better immunity to changes in the
environment which includes temperature and degradation
of components, improved versatility by modifying the
software, increasing advanced control methods, and
decreased number of the components are the key benefits
of the digital control against the analog control. A
structured and concise strategy for designing a digitally
operated close-loop Dc / Dc buck converter is discussed in
this paper beginning with the Buck converter and giving
the set of certain performance specification,
implementations of the digital Proportional-IntegralDerivative(PID) controller is made. It addresses in depth
all the appropriate DSP hardware and/or software
methods and approaches needed to implement a
controller. In order to illustrate the efficacy of the model,
the dynamic response as well as the steady-state
performance of controller is provided. The experimental
outcomes fit well with the model of simulation. During the
implementations of Switch Mode Power Supply (SMPS),
application of dsPIC provides new perspectives towards
affordable and versatile approaches of digital control.

— Sanitizing hands is a simple act that pays in
dividends when it comes to keeping ourselves healthy and
safe. Hand sanitizing is also one of the key cornerstones of
COVID- 19 prevention. Using a squeezing type sanitizer
container spout in public places (hospitals, schools,
shopping centers, industry plants and workplaces) is
unsafe as it was touched by many hands. Therefore there is
a need of automate the squeezing operation which
guarantee a legitimate cleanliness and safe to use as touch
less operation. Proposed unit is based on pre-programmed
electronics and an inbuilt ultrasonic sensor. It detects
hands when it comes in its programmed range and
machine start pouring set amount of liquid into hand.
Additionally there is preset delay is provided to serviceable and efficient use.

Carbon dioxide (CO2) is the reason of
increasing the global warming resulting from human
industrial activities, to reduce these emissions of CO2 there
is a necessity for sequestration of CO2 into stable forms. The
paper summarizes the mechanical properties of concrete
when cured on CO2 that is by using CO2 chamber. The
research includes designing a concrete mix of M25 and M30
grade as per IS 10262:2009. The experimental study on
water cured and CO2 specimens for compression strength
were carried out. The results show that for M25 and M30
grade of concrete has achieved increasing value as
comparing with 7days of water curing and the duration of
4hour CO2 curing. For M25 grade of concrete has achieved
70% of compression strength and M30 grade of concrete has
achieved 65% of compression strength in the duration of
4hours of CO2 cured specimens when compared to 28days of water cured specimens.

The improvements in the internet
infrastructure and the increased affordability has led to an
increase in the number of users on this platform. This has
put a large impact on the services being offered on this
platform especially on the e-commerce websites. These
websites cater to the individual and the increased number
of users has led to an increase in customer data. This data
is highly valuable as it can allow for the effective
prediction of customer behavior. Therefore, these
predictions can allow for effective and accurate product
recommendations based on the interests and the behavior
of the customer. To achieve this approach, this research
article analyzes a collection of related works based on the
paradigm of product recommendation. After a thorough
analysis, an improved product recommendation system is
devised through the effective implementation of Natural
Language Processing and machine learning algorithms.
