Published: April 2023

Було проаналізовано велику кількість літературних джерел щодо доцільності вибору саме моделі CNN. В них описувались всі сильні сторони даної структури нейронної мережі. Розглядається задача класифікації за допомогою нейронної моделі CNN та OpenCV. За допомогою OpenCV можна обробляти відеопотоки у реальному часі, а вже за допомогою тренованої моделі класифікувати розкадровані зображення. Таким чином ціллю дослідження є моделювання архітектури моделі таким чином, щоб мінімізувати час класифікації та збільшити її точність. Також покращити швидкість класифікації можна за допомогою багатопоточності. Для повного аналізу дослідження слід розглянути принцип роботи CNN. Це клас глибоких нейронних згорткових мереж, які можуть розпізнавати і класифікувати певні ознаки зображень і широко використовуються для аналізу візуальних образів. У ході проведення експериментів використовується модель класифікації CNN. Для порівняння результатів підібрані різні параметри. Такі як оптимайзери та кількості епох, щоб отримати інформацію про найоптимальніші варіанти. Під час проведення експериментів відбувались тренування з різними розмірами епох та оптимайзерами. Для покращення швидкості було підібрано 2 найбільш результативні, а саме “Adam” та “RMSProp”, тому що при виборі інших – точність різко падала до значень менше 40%.Для визначення ефективності одного над іншим, ми виконували тренування та класифікацію зображень з однаковими параметрами. При збільшенні кількості епох можна помітити позитивну динаміку по точності і негативну динаміку по втратах на обох моделях при зільшенні кількості епох. Це підтверджує результативність СNN для свого прямого призначення, а саме класифікації зображень. Також у роботі були проведені експерименти над розміром зображення. В результаті даного експерименту час тренування зменшився ще на 8 с на одній епосі, на основі того, що розмір вхідної матриці пікселів зображення став меншим. Також проведені експеременти довели, що при оптимальному підборі розміру зображення можна також збільшити швидкість обробки. Після підбору усіх оптимальних вхідних параметрів нейронної мережі був проаналізований процес розпаралелелення класифікації. В роботі пропонуються способи оптимізації моделі.

Перехід закладів вищої освіти України до роботи в режимі онлайн спричинив бурхливий розвиток і впровадження у роботу різноманітних онлайн-сервісів та служб, які викладачі використовують для проведення різного роду занять. Існують різноманітні сервіси, які рекомендовані міністерством освіти і науки України, і сервіси, що випробовують у тестовому режимі заклади вищої освіти та викладачі, через що можуть виникати технічні проблеми різного роду. Окрім того, якість роботи будь-яких сервісів, які використовуються в закладах освіти, залежить від стану матеріально-технічної бази, залежностей, високого рівня доступності. Для визначення характеру і джерела проблеми у роботі інформаційних служб необхідно впровадження системи для проведення збору даних, визначенні метрик та відповідних автоматичних дій або відправленні сповіщень відповідальним фахівцям. Результати аналізу отриманих даних надають можливість виявлення слабких місць у роботі будь-якої служби мережевої інфраструктури, визначати попит та важливість окремих служб та сервісів, що забезпечують функціонування інформаційного забезпечення роботи закладу освіти, а також дозволять приймати аргументовані рішення, щодо визначення місця розгортання сервісу (на власному сервері чи у хмарі), ефективності роботи сервісу протягом певного часу (налаштовування роботи у певні години, чи повному видаленні сервісу, як такого що не використовується, або не є визначним та критичним для функціонування системи загалом). Таким чином наявність системи для моніторингу інформаційної інфраструктури закладу вищої освіти є одним із пріоритетних напрямів дослідження. У статті наведено приклад встановлення та налаштування серверу та клієнта Zabbix, а також приклад налаштування моніторингу сервера під управління операційної системи Linux, встановлення додаткових шаблонів для моніторингу роботи веб-серверу і роботи сервісу ssh.

Policies and strategies for the development of artificial intelligence in the countries of the world: quo vadis? (part 1)
Authors: Androshchuk H. O.
Published: April 2023

The organizational and economic and legal aspects of the development and implementation of policies and strategies for the development of artificial intelligence (AI) in the leading countries of the world have been studied. All major economies (more than 60 countries) have developed national policies (strategies) for the development of AI. The following countries are considered advanced in the implementation of national AI strategies: USA, China, Canada, UK, Japan, UAE, France, Germany, South Korea, India and most countries of the European Union (EU). The structure of AI development strategies, priorities, funding models were considered, the main principles of the development and use of AI technologies, priority directions, goals and objectives of the use of AI were analyzed. The problems associated with the use of AI are highlighted: these are issues of data for processing AI, control over the use of AI, tracking AI decisions and responsibility for their adoption, control over confidentiality, ensuring the protection of personal data. Comparing the Ukrainian concept of AI development with the strategies of developed countries, we can conclude that it will not contribute to the effective development of AI, since investments in AI technologies differ hundreds of times, incentive tools and specific actions for the development of AI are not provided. The Institute of Artificial Intelligence Problems of the Ministry of Education and Science of Ukraine and the National Academy of Sciences of Ukraine have developed a project of the Strategy for the Development of Artificial Intelligence in Ukraine for 2022–2030. The Cabinet of Ministers of Ukraine needs to take measures to adopt the Strategy for the Development of Artificial Intelligence in Ukraine. It is concluded that there is a process of formation of two large spaces in the field of AI technologies in the international arena: the first unites the OECD countries with the unconditional financial, technological and value-normative dominance of the USA and the EU. The second is formed around China, in whose orbit countries fall, for which cooperation with the West is complicated due to a wide range of international conflicts (including Russia). Countries that are unable to resist the technological hegemony of China and the United States are faced with the dilemma of choosing between two large technological spaces.
Hydraulic calculation of group water intakes on underground wells equipped with pumps with variable speed drives
Authors: Баранчикова Н.И. , Епифанов С.П. , Дытте А.Г.
Published: April 2023

Применение частотных преобразователей на групповых водозаборах из подземных источников в системах водоснабжения направлено на экономию электроэнергии, организацию эффективных режимов, повышение технологичности управления, однако без достаточного обоснования не всегда приводит к желаемому результату. Одной из причин этого является отсутствие расчета с помощью эффективной математической модели, описывающей движение воды в водоносных горизонтах, скважинах, водоподъемных трубах и сборных коллекторах с учетом всех необходимых ограничений, в том числе на параметры режима при использовании частотных преобразователей на части или на всех погружных насосах. Модель представлена в виде задачи оптимизации, в которой целевая функция является суммарной потребляемой мощностью всеми погружными насосами, участвующими в работе. Предлагаемая оптимизационная модель позволяет описывать режимы функционирования групповых водозаборов от границы контура питания водозабора до резервуаров. Все ограничения задачи оптимизации можно разделить на три непересекающиеся группы: балансовые, технологические и режимные. Вычислив расходы электроэнергии по всем значимым режимам в течение года и сравнив их с затратами при существующих режимах без использования частотных преобразователей, можно сделать обоснованный вывод о целесообразности применения частотного электропривода, в том числе на один или несколько погружных насосов. Предложенная модель позволяет осуществлять организацию не только эффективных, но и технологически допустимых режимов.

The use of variable speed drives at group water intakes on underground sources in water supply systems is aimed at saving electricity, ensuring efficient operation modes, improving the management engineering; however, without sufficient justification the desired result is not always effected. One of the reasons is the lack of calculation using an effective mathematical model that describes the movement of water in aquifers, wells, lift pipes and gathering mains, taking into account all the existing limitations, including the mode parameters while using variable speed drives in some or in all submersible pumps. The model is submitted in the form of an optimization task where the target function is the total power input of all the operating submersible pumps. The proposed optimization model provides for describing the modes of the group water intakes operating from the intake external boundary to the tanks. All the limitations of the optimization task can be divided into three non-overlapping groups as follows: balance, technologic, and performance ones. Having calculated the electricity consumption for all significant modes during the year and compared them with the costs at the existing modes without variable speed drives, we can make a reasonable conclusion about the applicability of a variable speed drive in one or more submersible pumps. The proposed model provides for arranging both efficient and technologically allowable operating modes.

На селитебных территориях, являющихся местом проживания и разнообразной деятельности населения, образуется значительное количество твердых материалов различного происхождения и дисперсности, которые могут быть определены как мусор (или городской смёт – для дорог). При взаимодействии с атмосферными осадками этот мусор попадает в централизованные системы водоотведения, что нарушает их работу («Правила холодного водоснабжения и водоотведения»). Для решения данной проблемы были проведены экспериментальные исследования по оценке возможностей удаления мусора из поверхностного стока с помощью фильтра ФОПС®-К (корзинного типа). В качестве экспериментальной селитебной территории, на которую поступал мусор биологического, антропогенного и техногенного происхождения, была выбрана площадка кампуса университета. Результаты тестовых испытаний фильтра ФОПС®-К в течение двух циклов (каждый по 12 месяцев) показали, что его применение обеспечивает очистку поверхностного стока не только от крупного мусора, но и от значительной части песка (3/4 сухой общей массы) до размера исключения 0,04 мм. Установлено, что все компоненты мусора, собранные фильтром, содержат нефтепродукты в количестве 3–66,3 г/кг. В процессе испытаний удаление мусора из фильтра ФОПС®-К проводилось периодически (один раз в 3 месяца).

In residential areas that are places of residence and various activities of the population, a significant amount of solid materials of various origin and dispersion is formed that can be defined as debris (or municipal sweepings for roads). While interacting with atmospheric precipitation, this debris enters public wastewater disposal systems disrupting their operation («Rules for cold water supply and wastewater disposal»). To solve this problem, experimental studies were carried out to estimate possible removing debris from surface runoff using a FOPS®-K filter (basket type). The premises of the university campus was chosen as an experimental residential area where debris of biological, anthropogenic and technogenic origin accumulated. The results of testing FOPS®-K filter for two cycles (each for 12 months) showed that using the filter provided for removing not only large debris but also a significant part of the sand (3/4 of the total dry matter) from the surface runoff up to the size except 0.04 mm. It was established that all components of the debris captured by the filter contained 3–66.3 g/kg of oil products. During the tests, the debris was regularly removed from FOPS®-K filter (once every 3 months).

Анализируются вопросы развития нормативного регулирования обращения с осадками сточных вод. Даются рекомендации для организаций водопроводно-канализационного хозяйства по отнесению прошедших обработку осадков сточных вод к побочному продукту производства или к вторичному ресурсу. Отмечается, что анонсированный Минприроды России переход к экономике замкнутого цикла требует развития нормативно-правовой базы, однако паспорт федерального проекта «Экономика замкнутого цикла» и презентационные материалы Минэкономразвития РФ и публично-правовой компании «Российский экологический оператор» ограничивают вопросы экономики замкнутого цикла исключительно задачами в сфере обращения с отходами, что несет в себе высокие риски значительных издержек, связанных с признанием осадков сточных вод отходом. Введение новых, нормативно закрепленных понятий «вторичное сырье» и «побочный продукт производства» должно сыграть решающую роль в развитии регулирования процессов обращения с осадками сточных вод и вовлечения их в хозяйственную деятельность в качестве товаров.

The issues of developing statutory regulation for wastewater sludge treatment are analyzed. Recommendations are given for water supply and wastewater disposal providers on classifying treated wastewater sludge as a by-product or a secondary resource. It is noted that the transition to a circular economy announced by the Ministry of Natural Resources of Russia involves the development of a regulatory framework; however, the passport of the federal project «Circular Economy» and presentation materials of the Ministry of Economic Development of the Russian Federation and the public-law company «Russian Ecological Operator» reduce the issues of the circular economy exclusively to the tasks in waste management, which carries high risks of significant costs associated with referring wastewater sludge to wastes. The introduction of new, statutory formalized concepts of «secondary raw materials» and «by-products of production» should play a decisive role in developing the regulation of wastewater sludge handling processes and using it in the economic activities as goods.

Authors: Yamanashi Yuki , Hosoya Takuya , Yoshikawa Nobuyuki
Published: April 2023

In this study, we demonstrate a novel method for the reconfiguration of a nondestructively readable memory cell for superconductor integrated circuits. The proposed reconfiguration method involves the direct injection of flux quantum to the storage loop of the memory cell, which has been achieved using interface circuits in previous studies. By applying this method, the footprint of the superconductor memory cell can be reduced by half. We experimentally demonstrate the proof-of-concept of the investigated reconfiguration method. We expect that the memory cell reconfigured using the proposed method will be suitable for building large-scale lookup tables using superconductor circuits.

Published: April 2023

Optical and thermal characteristics of discharge channels during dark periods are observed by a high-sensitivity experimental platform. A narrow thermal channel is found to act as a bridge to connect the residual discharge channel to the anode. Compared to the residual hot channel, the narrow thermal channel exhibits marked differences in thermal evolutions, maintaining temperature of about 800 K and a thermal diameter of 0.8 mm. The narrow channel is expected to correspond to the weak luminosity with ionization activity on optical images, supporting the hypothesis that the reactivation of discharge channels in restrike originates from the channel tip.

Published: April 2023

Atmospheric-pressure plasma etching of a gallium nitride (GaN) substrate using hydrogen radicals instead of chlorine radicals was investigated toward the backside thinning of GaN vertical power devices to reduce on-resistance. As a basic experiment, a pipe-shaped electrode was placed facing the GaN substrate to generate atmospheric-pressure plasma of a gas mixture of helium and hydrogen and high-speed etching of approximately 4 μm min−1 was achieved. Although many spherical Ga metal particles were observed on the surface after processing, the addition of oxygen gas was found to be able to suppress them.

Published: April 2023

Omnidirectional Videos (or 360° videos) are widely used in Virtual Reality (VR) to facilitate immersive and interactive viewing experiences. However, the limited spatial resolution in 360° videos does not allow for each degree of view to be represented with adequate pixels, limiting the visual quality offered in the immersive experience. Deep learning Video Super-Resolution (VSR) techniques used for conventional videos could provide a promising software-based solution; however, these techniques do not tackle the distortion present in equirectangular projections of 360° video signals. An additional obstacle is the limited 360° video datasets to study. To address these issues, this paper creates a novel 360° Video Dataset (360VDS) with a study of the extensibility of conventional VSR models to 360° videos. This paper further proposes a novel deep learning model for 360° Video Super-Resolution (360° VSR), called Spherical Signal Super-resolution with a Proportioned Optimisation (S3PO). S3PO adopts recurrent modelling with an attention mechanism, unbound from conventional VSR techniques like alignment. With a purpose-built feature extractor and a novel loss function addressing spherical distortion, S3PO outperforms most state-of-the-art conventional VSR models and 360° specific super-resolution models on 360° video datasets. A step-wise ablation study is presented to understand and demonstrate the impact of the chosen architectural subcomponents, targeted training and optimisation.

Side-channel attack (SCA) is regarded as a sig- nificant risk to the hardware implementation of cryptographic systems. Side-channel information, such as timing, power, and electromagnetic radiation, is leaked through the system and can be exploited for secret key extraction. The work proposes a real- time and compatible detection method for power SCAs. The technique makes use of a switched capacitor DC-DC (SC-DCDC) converter along with a lightweight artificial intelligence engine for power SCA detection. The proposed system, referred to as EoH, has the ability to perform dynamic voltage scaling and learn the behaviors of the cryptographic system to identify any potential attacks. The switching activities of the SC-DCDC converter can be viewed as a measurement of the cryptographic function. Thus, the recurrent neural network was chosen as it best processes timeseries data. The technique is system-specific, meaning that during the enrollment phase, the normal operation of the system is learned. The technique can also be expanded to include other types of SCA and is not limited to power.

Gangrene of the hepatic ligaments (falciform and/or round) is an exceptional and poorly understood condition and may present a diagnostic dilemma. We report a case of necrotic falciform ligament abscess with pylephlebitis secondary to pyocholecyst. The clinical picture was impressive and noisy. The diagnosis was evoked on the CT scan, with the discovery of a circumscribed lesion of fatty density, pre-hepatic, in the fissure of the round ligament, at the junction of segments III and IV of the liver. The interest of surgical exploration is mainly diagnostic insofar as the evolution is always favourable, independently of the modalities of excision of the necrotic zones. In this article, we discuss the diagnostic and therapeutic features of this entit.

Comparative economic analysis using present net worth method was carried for 1 km of rigid and flexible pavement of Isieke Road, Ebonyi State. Information on the initial construction cost of the given length of the road, the maintenance cost, the rehabilitation cost, the salvage cost and the user cost which were obtained from the Ministry of Works, Ebonyi State, were used to assess the life cycle cost of the each alternative using the present net worth method. Comparisons between the various costs used to determine the life cycle cost for both rigid and flexible pavement showed that except the initial cost of construction where the rigid pavement is considerably higher than the flexible pavement, the other costs show the flexible pavement being on the high side. The summary cost showed that the for the period of 40 years which was the period of study in this work, the life cycle cost (LCC) of rigid pavement is 8.52% lower than that of the flexible pavement. Considering economy, this savings in LCC makes it a more viable alternative to flexible pavement.

Primary plasma cell leukemia (pPCL) is a rare lymphoproliferative disease characterized by a malignant proliferation of plasma cells in the bone marrow and peripheral blood. It is either primary (in 60% of cases) or a secondary complication of multiple myeloma [1]. In this context, we report the case of a 37-year-old patient with respiratory distress, whose bone marrow smear showed the presence of 64% of dystrophic plasma cells. A serum protein electrophoresis with immunofixation was performed, revealing results in favor of pPCL. A cytogenetic study was not performed due to lack of resources. The patient was put on multidrug therapy with a favorable evolution.

Introduction: There are millions of people in the world but no two humans are exactly alike not even identical twins. Genetic variations in man are caused by several environmental factors acting alongside with selection, gene flow, genetic drift and migration. Studies have been done on morphogenetic traits such as the pattern of hand clasping in some parts of Africa and among some tribes in southern region of Nigeria but there is no available data on the pattern of hand clasping among the Idoma tribe of Benue State. Hence, this study aimed to determine the pattern of hand clasping among the Idoma people of Benue State, Nigeria. Materials and Methods: The study was community-based, descriptive, and cross-sectional with a sample size of 401. Data was collected using a closed-ended questionnaire that was administered by an interviewer following an examination of hand clasping pattern. Results and Discussion: The proportion of participants that expressed hand clasping with the left thumb on top was 16.7%, while right thumb on top was 83.3%. There were no significant socio-demographic characteristics among participants (p > 0.05). Conclusions: The study implies that hand clasping with the right thumb on top is a marked characteristic of the people of Idoma and, as such, can be used to identify them amongst other tribes where the identity of the tribes is not known ab initio.

Background: Over the years, aligner therapy has undergone a great evolution. The use of aligners is now an alternative to braces for aesthetic reasons. Their effectiveness and impact have yet to be evaluated. Objective: The objective of this study was to compare the effectiveness of dental movements with aligners versus the use of conventional appliances, as well as the effectiveness and impact on periodontal health and root resorption. Materials and Methods: A systematic search of PubMed, Ebsco Host and Scopus was performed using a well-designed formula. Articles published in the last 10 years in English and French were included after filtering the titles, abstracts then full texts. Results: Twenty-six records were deemed suitable for the objectives of our systematic review. All records focused on the comparison of treatment with aligners and fixed appliances. The difference in treatment and time efficiency was assessed in 17 papers, 6 papers evaluated the impact of orthodontic appliances on periodontal health, and the remaining 3 records focused on the occurrence of root resorption. Conclusion: Clear aligners produce clinically acceptable outcomes that could be comparable to fixed appliance therapy. Aligners facilitate oral hygiene practices which results in better periodontal health. However, it appears that Invisalign may not be as effective as fixed appliances in achieving certain tooth movements like vertical, radicular and rotational movements.
Medical Ethics of Pediatric Care

Published: April 2023

Clinical research ethics is founded on a few well-known rules and papers. The criteria differ from country to country, but the ideals of respect for humans, beneficence, and fairness remain consistent. These values are expressed in criteria for obtaining free and informed consent, minimizing risk or damage, and without disproportionately burdening or disadvantageous specific people. In hospitals, physicians frequently confront ethical difficulties that need appropriate abilities and the capacity to detect and manage. For research to be ethical, it must also be of such high quality and performed in such a way that it produces known and usable knowledge. Youngsters have a reduced ability for comprehension and may be more susceptible to compulsion. As a result, kids are seen as a particularly vulnerable demographic, and specific provisions for children are included in many standards. The level of risk permissible for minors participating in research is an important topic in these clauses. While it is widely acknowledged that children deserve special care due to their fragility, there is growing concern that children in general should not be disadvantaged by a lack of information because of decreasing research activities. The purpose of this study was to examine the ethical issues faced by physicians and nurses with medical education and pediatric care responsibilities, as well as whether those issues are related to their workplace, medical specialty, and area of clinical practice, as well as the primary role of parents and children in adhering to these ethics.

contexts during their stay abroad. In this empirical study, we examined how a group of international students (n=10) in France used their smartphones during the eight-week lockdown that imposed on everyone a stay-at-home order and allowed minimal physical contact (April and May 2020). We collected data about students’ use thanks to a self-tracking app and interviews. Drawing on literature from the fields of language education, communication, and psychology, we considered advantages and limitations of smartphone use by international students pertaining to three aspects of their lives: (1) emotional management, (2) language and culture learning, and (3) sociocultural adaptation. Since international students were in the host country, but without the social life on campus that usually makes immersion abroad so special, this study led us to reflections about immersion and inclusion in education abroad.
Abstract in French
Les smartphones accompagnent les étudiants internationaux dans leur adaptation à différents contextes pendant leur séjour à l'étranger. Dans cette étude empirique, nous avons examiné comment un groupe d'étudiants internationaux (n=10) en France a utilisé leurs smartphones pendant le confinement de 8 semaines qui a imposé à tous de rester à la maison et a engendré un contact physique minimal (avril et mai 2020). Nous avons recueilli des données sur les usages des étudiants grâce à une application d’auto-suivi et des entretiens. En nous appuyant sur la littérature dans les domaines de l'enseignement des langues, de la communication et de la psychologie, nous avons examiné les avantages et les limites de l'utilisation du smartphone par les étudiants internationaux en ce qui concerne trois aspects de leur vie : (1) la gestion des émotions, (2) l'apprentissage de la langue et de la culture, et (3) l'adaptation socioculturelle. Étant donné que les étudiants internationaux se trouvaient dans le pays d'accueil, mais sans la vie sociale sur le campus qui rend habituellement l'immersion à l'étranger si spéciale, cette étude nous a amenés à réfléchir à l'immersion et à l'inclusion dans l'éducation à l'étranger.
