ANH is a business engaged in the distribution of goods with a model of selling and buying goods. The distribution process of goods sold is goods purchased from several suppliers which are then collected and resold. In the process of distributing goods, it is done manually, starting with recording requests to suppliers and customers with note media as proof of transactions. The documentation process for recording proof of transactions often results in documentation errors due to several factors, including, (1) the possibility of adding or reducing ordered products due to changes in orders and not properly documented on notes. (2) the customer contacts ANH again or vice versa to confirm stock availability in the warehouse in real time. Solving problems that occur at ANH can be solved with a good management information system by utilizing technology. The design aimed at solving the problem is to reduce errors in the documentation process by using notes that sometimes change in the field, processing records more quickly and integrated so as to reduce the risk of errors in providing information on goods in the warehouse and errors in the process of inputting purchase requests. The development method used is the iteration method. Analysis of the problems that occur in ANH uses the PIECES (Performance, Information, Economic, Control, Efficiency, Service) framework problem analysis.

Published: June 2024

Choosing an internet-based application as a communication tool is considered a smart decision due to its ability to deliver information or messages to users anywhere without being limited by region or location. An application created by an institution can provide important information about the institution's activities to users, while users can access detailed data through the application. Currently, the Dapodik application has been implemented in various schools in Kabupaten Karawang. However, the use of this application faces several problems, including frequent system errors that cause double transactions and require a long time to update data. Based on these problems, this study was conducted to determine the extent of the advantages and disadvantages of the Dapodik application. The research was conducted using the Use Questionnaire and Importance Performance Analysis methods using a questionnaire distributed to 50 application users using google form. The results of this study obtained with the Importance Performance Analysis method produce a priority map for improving the Dapodik application. The map is divided into quadrant I as the top priority from the user's perspective. In quadrant II, there are aspects of the Dapodik application which are areas of achievement or excellence that must be maintained because they have met user expectations, namely the appearance of the Dapodik application is easy to recognize, the Dapodik application is easy to operate and the color combination of the Dapodik application is pleasing to the eye and not boring.
Distributed Asynchronous Service Provisioning in the Edge-Cloud Multi-tier Network
Authors: Cohen Itamar , Chiasserini Carla Fabiana
Published: June 2024

In an edge-cloud multi-tier network, datacenters provide services to mobile users, with each service having specific latency constraints and computational requirements. Deploying such a variety of services while matching their requirements with the available computing resources is challenging. In addition, time-critical services may have to be migrated as the users move, to keep fulfilling their latency constraints. Unlike previous work relying on an orchestrator with an always-updated global view of the available resources and the users’ locations, this work envisions a distributed solution to the above problems. In particular, we propose a distributed asynchronous framework for service deployment in the edge-cloud that increases the system resilience by avoiding a single point of failure, as in the case of a central orchestrator. Our solution ensures cost-efficient feasible placement of services, while using negligible bandwidth. Our results, obtained through trace-driven, large-scale simulations, show that the proposed solution provides performance very close to those obtained by state-of-the-art centralized solutions, and at the cost of a small communication overhead.

Authors: Moorthy Sabarish Krishna , Jagannath Jithin
Published: June 2024

The exponential increase in Internet of Things (IoT) devices coupled
with 6G pushing towards higher data rates and connected devices has
sparked a surge in data. Consequently, harnessing the full potential of
data-driven machine learning has become one of the important thrusts. In
addition to the advancement in wireless technology, it is important to
efficiently use the resources available and meet the users’
requirements. Graph Neural Networks (GNNs) have emerged as a promising
paradigm for effectively modeling and extracting insights which
inherently exhibit complex network structures due to its high
performance and accuracy, scalability, adaptability, and resource
efficiency. There is a lack of a comprehensive survey that focuses on
the applications and advances GNN has made in the context of IoT and
Next Generation (NextG) networks. To bridge that gap, this survey starts
by providing a detailed description of GNN’s terminologies,
architecture, and the different types of GNNs. Then we provide a
comprehensive survey of the advancements in applying GNNs for IoT from
the perspective of data fusion and intrusion detection. Thereafter, we
survey the impact GNN has made in improving spectrum awareness. Next, we
provide a detailed account of how GNN has been leveraged for networking
and tactical systems. Through this survey, we aim to provide a
comprehensive resource for researchers to learn more about GNN in the
context of wireless networks, and understand its state-of-the-art use
cases while contrasting to other machine learning approaches. Finally,
we also discussed the challenges and wide range of future research
directions to further motivate the use of GNN for IoT and NextG
Networks.

Synthesis and antibacterial screening of some new 1'2'3 -triazole derivatives from dapsone
Authors: Hasan Mohammed Marhoon  , Ezzat Hussein Zimam
Published: June 2024

In our relentless pursuit of developing innovative antibacterial derivatives, we have successfully generated and evaluated a novel series of 1,2,3-triazole derivatives derived from azo dapsone. The synthesis process commenced with the fusion of the dapsone core with the triazole framework, establishing a solid foundation for our synthetic endeavors. Subsequently, the azo dapsone nucleus underwent functionalization using sodium azide, resulting in the creation of an azide derivative (B).
To synthesize the desired end 1,2,3-triazoles, a click reaction was employed, combining the azide compound with triple bond derivatives. The structures of all the synthesized compounds were meticulously characterized through the utilization of advanced techniques such as Nuclear Magnetic Resonance (NMR) and Infrared (IR) spectroscopy.
Following the successful synthesis and characterization, our focus shifted to evaluating the in vitro antibacterial activity of these compounds against two significant bacterial strains: the gram-positive bacterium Staphylococcus aureus and the gram-negative bacterium Escherichia coli. Among the compounds synthesized, one compound in particular, designated as (H2), exhibited exceptional potency against Staphylococcus aureus with a minimal inhibitory concentration (MIC) of 25 μg/mL, surpassing the activity of all other prepared compounds. Similarly, compound (H1) displayed remarkable efficacy against Escherichia coli with an MIC of 22 μg/mL, outperforming the other end compounds.
These findings demonstrate the tremendous potential of our synthetic approach in generating dapsone derivatives with enhanced antibacterial activity. Our research represents a significant step forward in the development of novel and potent antibacterial agents.

Published: June 2024

The research was held in Kailali District of Nepal to assess the effect of different packaging materials on shelf life and quality of banana fruit. The experimental set up was done in Completely Randomized Design (CRD) with five treatments of different packaging, each replicated four times. There were five different treatments used for the study and they were allotted as follows: T1: No packaging/open (control) T2: Banana leaf, T3: Straw, T4: Polythene bag, T5: Cardboard box. A digital hygrometer for measuring relative humidity and thermometer for measuring temperature were used. RH was recorded every 3rd day. Similarly, temperature was also recorded during those days. R-Studio 4.2.2 version was used for data analysis. TSS was found highest in polythene bag followed by cardboard box and lowest was control followed by straw. TSS (16.020 Brix) was found in polythene bag at 13th day and lowest TSS (5.250 Brix) in at 1st day. At 16th day, maximum TSS was found in polythene bag (15.320 Brix) and minimum in control (12.720 Brix). Titrable Acidity (TA) tends to increase at initial stage but later decreases with increase in storage time. The highest TA (0.32%) was found in polythene bag and lowest (0.24%) was found in control at day 16th. Physiological Loss in Weigh t(PLW) tends to increases with increase in storage time. The highest PLW (27.68 gm) was found in Control and lowest loss (21.61 gm) was found in polythene bag at day 16th. The firmness was decreased with the advancement in storage time in all treatments. The highest firmness (9.385kgcm-2) was found in polythene bag at 1st day and lowest (9.12 kgcm-2) was found in control at 1st day. At the end of the day i.e., at day 16th, maximum firmness was observed in Polythene bag (3.34 kgcm-2), and minimum was observed in control (2.07 kgcm-2) and pulp thickness tends to increase with increase in storage time. At day 16th, the highest pulp thickness (3.34 cm) was found on banana leaf and lowest (2.07 cm) on straw. Based on these findings, it is evident that packaging bananas in polythene bags resulted in significant improvements in weight loss, TA, firmness, TSS, pulp thickness, and peel thickness. This suggests that using polythene bags as packaging material provides better quality and extends the shelf life of bananas compared to the other materials tested in the study.

Conceptual Review: Cultivating Learner Autonomy Through Self-Directed Learning & Self-Regulated Learning: A Socio-Constructivist Exploration
Authors: Kharroubi Sara , ElMediouni Abdeljabbar
Published: June 2024

This paper proposes a comprehensive framework for fostering learner autonomy (LA) in educational settings by integrating socio-constructivist principles with self-directed learning (SDL) and self-regulated learning (SRL). Emphasizing LA as both a learning process and a personal capacity, the framework draws on Vygotskian socio-cultural principles and Piagetian cognitive development. It underscores the importance of fostering LA in the contemporary "post-truth" classroom, where critical thinking and information literacy are paramount. Through analysis, three key insights emerge: socio-constructivism highlights the interplay between social interactions and individual cognitive development, SDL serves as the pathway to LA by empowering learners to control their learning, and SRL integrates metacognition for the metaliterate learner. Looking ahead, future research could explore effective pedagogical strategies, ensure learner agency and empowerment, and develop robust methods to assess LA and metaliteracy skills. By addressing these areas, educators can create environments conducive to cultivating self-directed, critical thinkers prepared for the challenges of the information age.

Recovery of iron phosphate and lithium carbonate from sulfuric acid leaching solutions of spent LiFePO4 batteries by chemical precipitation
Authors: Jing Chen , Tran Thanh Tuan , Lee Man Seung
Published: June 2024

The recycling of lithium and iron from spent lithium iron phosphate (LiFePO4) batteries has gained attention due to the explosive growth of the electric vehicle market. To recover both of these metal ions from the sulfuric acid leaching solution of spent LiFePO4 batteries, a process based on precipitation was proposed in this study. Since ferric and ferrous ions coexisted in the leaching solution, all the ferrous ions were first oxidized to ferric ions by adding H2O2 to the leaching solution. About 99% iron(III) was recovered as iron phosphate by adjusting the solution pH to 2 at 25 oC for 30 mins. After the precipitation of iron phosphate, the remaining Li(I) in the filtrate was recovered as lithium carbonate by precipitation with Na2CO3 as a precipitant. Addition of acetone to the filtrate at room temperature greatly enhanced the precipitation percentage of Li(I). Moreover, solid Na2CO3 was better than Na2CO3 solution in precipitating Li(I). About 95% of lithium ions was recovered as carbonate precipitates under the optimum conditions: solution pH = 11, 3.0 molar ratio of solid Na2CO3 to Li(I), 7/5(v/v) volume ratio of acetone to the filtrate, 25 oC, 300 rpm for 2 hrs.

Приведены расчеты максимальных амплитуд различных видов качки и продольно-горизонтальных, поперечно-горизонтальных и вертикальных ускорений в различных точках судов при качке на различных курсовых углах. Выполнено сравнение расчетов по линейной и нелинейной теориям. Показано значительное влияние нелинейных сил на амплитуды качки и все составляющие ускорения. Данное влияние имеет место при увеличении балльности волнения. Проведено исследование влияния изменения относительной глубины на амплитуды и составляющие ускорения в условиях нерегулярного волнения. Показано значительное увеличение данных величин при уменьшении относительной глубины. Показано наибольшее влияние нелинейных сил второго порядка на вызываемые ими амплитуды качки и составляющие ускорения при качке судна лагом к волнению.

The paper deals with the determination of amplitudes of various types of motion and acceleration components taking into account the influence of nonlinear forces of the second order on an irregular wave in an infinitely deep water and in shallow water. The spectral method and linearization of nonlinear amplitudes of motion and acceleration obtained during calculations on regular waves are used to calculate amplitudes. Calculations of maximum amplitudes of various types of motion and longitudinal-horizontal, transverse-horizontal and vertical accelerations at various points of ships during motions at various course angles are given. Comparison of calculations by linear and nonlinear theories is performed. A significant influence of nonlinear forces on the amplitudes of motion and all components of acceleration is shown. This influence takes place at increasing of the wave grade. A study of the effect of changes in relative depth on amplitudes and acceleration components in irregular waves conditions has been carried out. A significant increase of these values with decreasing relative depth is shown. The greatest influence of nonlinear forces of the second order on the amplitudes of motions and acceleration components caused by them is shown in beam waves.

Процесс проектирования судовых кабельных трасс связан с принятием проектных решений по размещению кабеля в условиях повышенной насыщенностью помещений судна различными объектами. При этом должен соблюдаться «баланс» между минимальностью значений целевых критериев оптимальности и соблюдением ограничений на прокладку кабеля. В статье рассматривается модель построения судовых кабельных сетей на маршрутном графе с ограничениями по пропускным способностям ребер и допустимого сопротивления для соединений. В качестве целевых критериев оптимальности задачи рассматриваются стоимость и масса кабелей. Сама задача формулируется в терминах двухкритериальной задачи линейного программирования транспортного типа. Для упрощения поставленной задачи ее ограничения преобразуются с помощью метода разложения Данцига-Вольфа, а для ее решения рассматривается двухкритериальный метод последовательного улучшения плана, который выбирает марки кабелей в соответствии с их оптимальностью. На точность описанной модели влияет подход к моделированию длин кабелей, которая в реальных условиях постройки судна зачастую будет больше вычисленной проектной длины. Для компенсации связанных с этим «помех» предлагается использовать специальный коэффициент среднего отклонения, который умножается на целевые критерии и ограничения, тем самым приближает проектные длины к реальным.

The process of ship cable routing is associated with decisions making process on cable placement in conditions of increased saturation of various objects in the ship's compartments. In this case, a «balance» must be maintained between the minimum values of the target objective and compliance with the restrictions on cable laying. In this article describes a model for the ship cable routing problem on a route graph with restrictions on the capacity of the edges and the permissible resistance for connections. The cost and weight of cables are selected as target objective. The problem itself is formulated in terms of a bi-objective linear programming problem of multi-commodity minimum cost flow. To simplify the problem, its limitations are transformed using the Danzig-Wolf decomposition method, and to solve it, a two-criteria simplex method is proposed, which selects type of cable in accordance with their applying optimality. The accuracy of the described model is influenced by the approach to modeling cable lengths, which in real conditions of ship construction will often be greater than the calculated design length. To compensate for the “interference” associated with this, it is proposed to use a special average deviation coefficient, which is multiplied by target objectives and restrictions, bringing the design lengths closer to real ones.

В работе представлены вибрационные и теплотехнические испытания судовых главных винторулевых колонок различного технического состояния, выполненные на характерных режимах в эксплуатации и в условиях сухого дока. Достоинством контроля состояния по сигналам вибрации является не только возможность получения информации о предполагаемом отказе машины к определенному моменту времени, но и планирования мер по предотвращению этого отказа. В основу анализа входило рассмотрение критериев оценки параметров вибрации элементов главных винторулевых колонок и выявление неисправности, влияющей на повышения температуры масла и самопроизвольного поворота одной из колонки морского буксира. Выполненные исследования позволили выявить основные характерные частоты вибрации, влияющие на техническое состояние элементов главных винторулевых колонок морских буксиров. Приведенный пример измерения вибрации в условиях сухого дока доказал необходимость периодического применения безразборного вибрационного метода контроля для прогнозирования отказа или неисправности узлов подводных частей главных винторулевых колонок морских буксиров. Проводимые исследования судовых энергетических установок, на основе применения безразборных методов диагностики морских судов в эксплуатации, лежат в основе системы управления автономных судов.

The work presents vibration and thermal engineering tests of ship's main rotor columns of various technical conditions, performed under typical operating conditions and in dry dock conditions. The advantage of monitoring the condition by vibration signals is not only the possibility of obtaining information about the expected failure of the machine at a certain point in time, but also planning measures to prevent this failure. The analysis was based on the consideration of criteria for evaluating the vibration parameters of the elements of the main propeller columns and the identification of a malfunction affecting oil temperature increases and spontaneous rotation of one of the columns of a marine tugboat. The performed studies allowed us to identify the main characteristic vibration frequencies that affect the technical condition of the elements of the main propeller columns of marine tugs. The given example of vibration measurement in dry dock conditions proved the need for periodic use of a non-disassembled vibration control method to predict failure or malfunction of nodes of underwater parts of the main propeller columns of marine tugs. The ongoing research of marine power plants, based on the application of non-selective methods of diagnostics of marine vessels in operation, is the basis of the control system of autonomous vessels.

Обеспечение безопасности, в том числе на водном транспорте, является одной из приоритетных задач государства, которая направлена на снижение вероятности возникновения чрезвычайных ситуаций. Активное развитие научно – технологического прогресса влечёт за собой увеличение количества и тяжести чрезвычайных ситуаций, ликвидация последствий которых осуществляется силами и средствами Единой государственной системы предупреждения и ликвидации чрезвычайных ситуаций. Своевременное реагирование сил и средств и правильность принимаемых решений позволяет минимизировать социальные и материальные ресурсы на проведение аварийно-спасательных и других неотложных работ. Оптимизация процесса управления в подобных системах возможна с помощью соответствующих математических методов и моделей. В статье рассмотрена возможность применения метода экспоненциального программирования для решения задач оптимального распределения неоднородных ресурсов между частными задачами организационной системы для повышения эффективности реагирования на чрезвычайные ситуации на объектах водного транспорта. Представлен пример решения задачи экспоненциального программирования симплекс-методом дополненным правилом ограниченного ввода в базис. Применение разработанного метода позволит принимать оптимальные управленческие решения и снизить величину материального и социального ущерба с целью минимизации последствий чрезвычайных ситуаций.

Ensuring safety, including on water transport, is one of the priorities of the state, which is aimed at reducing the likelihood of emergency situations. The active development of scientific and technological progress entails an increase in the number and severity of emergency situations, the elimination of the consequences of which is carried out by the forces and means of the Unified State Emergency Prevention and Response System. The timely response of forces and means and the correctness of decisions made allows minimizing social and material resources for emergency rescue and other urgent work. Optimization of the management process in such systems is possible with the help of appropriate mathematical methods and models. The article considers the possibility of using the exponential programming method to solve problems of optimal distribution of heterogeneous resources between particular tasks of the organizational system to improve the effectiveness of emergency response at water transport facilities. An example of solving the exponential programming problem by the simplex method supplemented by the rule of limited input into the basis is presented. The application of the developed method will make it possible to make optimal management decisions and reduce the amount of material and social damage in order to minimize the consequences of emergency situations.

Рост промышленной деятельности на акваториях российского нефтегазового арктического шельфа сопровождается созданием различных специализированных многофункциональных грузоперевалочных комплексов, основу которых на трассе Северного морского пути представляют морские порты. Развитие портовой и прибрежной инфраструктуры неразрывно связано с необходимостью обеспечения бесперебойного и безаварийного функционирования порта, а в суровых условиях российской Арктики одним их важнейших вопросов является вопрос обозначения навигационных и экологических рисков в процессе эксплуатации планируемого объекта. В работе проведен детальный анализ непосредственно устьевой акватории реки Индига, выбранной в качестве наиболее подходящего места для возведения нового транспортного объекта. Обозначено значение специфических параметров окружающей природной среды при проектировании прибрежных морских объектов в зоне арктических морей. Представлена оценка влияния прибрежных волновых потоков как наносодвижущего фактора, и основания рассматривать их динамические процессы в комплексе с морфологическими особенностями исследуемой акватории как потенциальную угрозу блокировки будущей судоходной трассы песчаными перемычками. Обоснованы предложения по установке инженерных конструкций волногасящего типа для перекрытия потока наносов и защиты причальных линий от прямого волнового воздействия.

The growth of industrial activity in the waters of the Russian Arctic oil and gas shelf accompanied by the creation of various specialized multifunctional cargo complexes. Seaports represent the basis of cargo complexes on the route of the Northern Sea Route. The development of port and coastal infrastructure closely linked to ensuring trouble-free operation of the port. In the harsh conditions of the Russian Arctic, one of their most important issues is the designation of navigational and environmental risks of the new facility. The paper provides a detailed analysis of the mouth of the Indiga River. This water area has been chosen as the most suitable place for the construction of a new transport facility. The importance of specific environmental parameters in the design of coastal marine facilities in the Arctic seas zone indicated. The paper presents an assessment of the influence of coastal wave flows as a factor creating the shoal. The reasons are present to consider the dynamic processes and morphological features of the studied water area as a potential threat of blocking the future shipping route by sand bridges. The proposals for the installation of engineering wave-damping structures are substantiated. Their purpose is to block the flow of sediment and protect the marine berths from direct wave action.
