В работе рассматривается вариант использования пароводяного струйного аппарата (ПВСА) в качестве реактивного движителя на подводных аппаратах. Наиболее целесообразно для этих целей использовать ПВСА, предназначенный для обеспечения циркуляции теплоносителя в первом контуре. Особенностью такого ПВСА является сверхкритическое течение среды в диффузоре. Рассмотрен вариант, при котором водяной пар для работы такого ПВСА может быть получен путем сжигания водорода в среде кислорода. При этом целесообразно подавать воду в камеру сгорания, чтобы увеличить массовую долю водяного пара в парогазовой смеси. Проведены расчетно-теоретические исследования зависимости параметров ПВСА от глубины погружения. Исследования проводились для глубин до 1000 метров. По результатам, выполненных в работе исследований, установлено, что ПВСА с дозвуковым соплом, благодаря сверхкритическому течению двухфазного потока в диффузоре, может быть использован в качестве реактивного движителя на подводном аппарате. Необходимо только так выбрать параметры ПВСА, чтобы скачка конденсации в диффузоре не было.

The work considers the option of using a steam-water jet apparatus (PVSA) as a jet propulsion on underwater vehicles For these purposes, it is most expedient to use PVSA, designed to ensure the circulation of the coolant in the primary circuit. A feature of such a PVSA is the supercritical flow of the medium in the diffuser. A variant is considered in which the input steam for the operation of such a PVSA can be obtained by burning hydrogen in an oxygen environment. In this case, it is advisable to supply water to the combustion chamber in order to increase the mass fraction of water vapor in the gas-vapor mixture. Calculation-theoretical studies of the dependence of the PVSA parameters on the immersion depth have been carried out. The studies were carried out for depths up to 1000 meters. According to the results of the research work, it was found that a PVSA with a subsonic nozzle, due to the supercritical flow of a two-phase flow in a diffuser, can be used as a jet propulsion device on an underwater vehicle. It is only necessary to choose the PVSA parameters in such a way that there is no condensation jump in the diffuser.

Данная статья является продолжением исследований по проблемам разработки системы поддержки принятия решений безопасности судовождения (СППР) [1]. Первоосновой СППР является система автоматического мониторинга и контроля безопасности судовождения реального времени (САМК СБС) [2,3]. В этой области отсутствуют не только сопоставимые исследования, но даже отсутствует структурная концепция автоматического мониторинга и контроля движения судна в режиме реального времени. Поэтому направленность этой статьи заключается в рассмотрении совокупности некоторых принципов, которая определяет пути развития управляемой архитектуры автоматического мониторинга и контроля движения судна в режиме реального времени. Структура модели САМК СБС в режиме реального времени и пример вычислительного кластера для решения задачи внутренней безопасности судна, приведенные в статье, рассматриваются как основа создаваемой архитектуры системы реального времени. Важной функцией компьютерной системы является непрерывный мониторинг за судами, окружающей средой и внутренними системами судна для обнаружения аномального или опасного состояния. На основании измерительной информации САМК СБС, разрабатываемый подход позволяет достигать безопасности систем в режиме реального времени.

В статье представлено реляционное хранилище данных, созданное для предметной области «Экономические показатели рейса судна». Описано взаимодействие с хранилищем с помощью инструментальных средств. Реализация метода k-средних производилась с помощью библиотеки Scirit-learn для языка Python. Для определения оптимального числа кластеров в работе использовались метод «локтя» и метод «силуэта». В результате выполненного анализа можно определить долю того или иного типа судна в полученных кластерах и диапазон прибылей, которую может заработать судно с известными характеристиками за рейс. С помощью результатов кластеризации можно также искать конкурирующие суда в конкретном порту. Таким образом аналитик может принять некоторые решения для оптимизации расходов или улучшения логистики в целях увеличения прибыли.

The article presents a relational data warehouse created for the subject area "Economic indicators of a ship's voyage". Interaction with the repository using tools is described. The implementation of the k-means method was carried out using the Scirit-learn library for Python. To determine the optimal number of clusters, the following two methods were used: the "Elbow" method and the "Silhouette" method. As a result of the analysis, it is possible to determine the share of a particular type of vessel in the resulting clusters and the range of profits that a vessel with known characteristics can earn per voyage.

Одной из наиболее важных и сложных задач в управлении контейнерной линией является составление грузового плана контейнеровоза. Необходимость учитывать не только физические характеристики судна, но и коммерческие параметры контейнеров делает это задачу более сложной, чем составление грузового плана универсального судна. Вместимость современных контейнеровозов не позволяет решать эту задачу вручную. В мировой практике перевозок используются специализированные программные средства для составления и проверки грузового плана контейнеровоза. Изменение структуры рынка морских контейнерных перевозок приводит к необходимости решить задачу по автоматическому составлению грузового плана. Данная работа подтверждает, что решение этой задачи требует многоэтапного подхода. Одним из этапов составления грузового плана является распределение контейнеров по «бэям» судна. В статье представлен один из возможных алгоритмов распределения контейнеров по «бэям», основанный на средней массе контейнеров в каждом «бэе». Авторы показывают, что количество непроизводительных перемещений может быть сокращено за счет сортировки контейнеров по портам назначения. Следующим этапом исследования является решение задачи по распределению контейнеров внутри одного отдельного «бэя».

One of the most important and complicated tasks in the container line management is the development of containership’s bayplan. The requirement take into account not just physical characteristics of a ship, but also the commercial parameters of containers makes this task more complicated than generation of general-purpose ships’ cargo stowage plan. The container capacity of modern ship makes it impossible to create a bayplan without computerization. In the world practice special computer-aided systems are introduced to create and check a bayplan. The changes in container shipping market lead to the necessity to solve the problem of automatic bayplan generation. The paper shows that this solution requires multi-step approach. One of the possible step in the algorithm is to group the containers to the ship bays. The paper shows one of the possible methods to make it, based on the information about average bay weight. Authors prove that the number of unproductive moves can be reduced if the list of containers is sorted by the port of destination. The nest step of the research is to solve the task of container positioning within a bay.

Authors: Котенко А.Г.
Published: March 2023

В статье проводится анализ современных тенденций развития перевозок нефтеналивных грузов морским, железнодорожным и трубопроводным видами транспорта. Особое внимание уделяется изменениям, происходящим на железнодорожном и трубопроводном транспорте, как наиболее тесным партнерам и конкурентам морского вида транспорта. При этом отмечается устойчивость тенденций, направленных на усиление партнерства в рамках российского перевозочного рынка нефтеналивных грузов, которое обеспечивается за счет закрепления рыночных сегментов и участников рынка за видами транспорта. В качестве определяющих факторов деления рынка указываются: различная степень инерционности при изменении объемов поставок при использовании разных видов транспорта, влияние финансовых соглашений, неравномерность потребления, географические особенности перевозок. Проведенное автором исследование, охватывающее различные возможности транспортировки нефтеналивных грузов, показало, что основная причина ухода части груза с морского транспорта и железных дорог связано с поступательным развитием системы магистральных трубопроводов при фактическом отсутствии у морского и железнодорожного транспорта возможности конкурировать по цене с трубопроводным транспортом ввиду регуляторных ограничений. Кроме того, на данный процесс влияют такие технологические преимущества трубопроводного транспорта, как высокая пропускная способность, автоматизация процессов налива, перекачки и слива, а также минимизация потери груза.

The article analyzes current trends in the development of transportation of oil cargoes by sea, rail and pipeline modes of transport. Particular attention is paid to the changes taking place in the railway and pipeline transport, as the closest partners and competitors of the maritime mode of transport. At the same time, there is a stability of trends aimed at strengthening partnerships within the Russian transportation market for oil cargo, which is ensured by assigning market segments and market participants to modes of transport. The following factors are indicated as determining factors for dividing the market: a different degree of inertia when changing the volume of supplies when using different modes of transport, the impact of financial agreements, uneven consumption, geographical features of transportation. A study conducted by the author, covering various possibilities for transporting oil cargoes, showed that the main reason for the departure of part of the cargo from sea transport and railways is associated with the progressive development of the system of main pipelines, while sea and railway transport are virtually unable to compete on price with pipeline transport due to regulatory restrictions. . In addition, this process is influenced by such technological advantages of pipeline transport as high throughput, automation of loading, pumping and unloading processes, as well as minimizing cargo loss.

В данной работе представлены исследования влияния параметров режима импульсно-дуговой наплавки на микроструктуру наплавленного металла, полученного интенсивно развивающимся в наши дни методом проволочно-электродугового выращивания (WAAM) с использованием проволоки марки Св-AMg5 в защитной среде аргона. Установлена зависимость влияния режима наплавки на относительный размер зерна и его форму. При увеличении частоты импульсов тока в диапазоне от 13 до 55 Гц средний условный размер зерна увеличивается от 98 до 236 мкм. Условный эксцентриситет зерна также увеличивается. Зависимость среднего условного размера зерна от погонной энергии не обнаружена. При увеличении погонной энергии замечено уменьшение эксцентриситета зерна. Зависимость твердости наплавленного металла от режима наплавки не замечена. Среднее значение твердости лежит в пределах 66-68 HV. Результаты работы рекомендуется использовать для выбора частоты импульсов (влияющих также на размер капель) при разработке технологий проволочно-дугового выращивания из алюминиевых сплавов.

This paper presents studies of the influence of the parameters of the pulsed arc surfacing mode on the microstructure of the deposited metal produced by Wire Arc Additive Manufacturing (WAAM) using the Al-Mg alloy (AMg5 wire) with an argon gas-shield, which is being intensively developed today. The dependence of the influence of the surfacing mode on the relative size of the grain and its shape is established. With an increase in the frequency of current pulses in the range from 13 to 55 Hz, the average conditional grain size increases from 98 to 236 μm. The conditional grain eccentricity also increases. The dependence of the average conditional grain size on the heat input was not found. With an increase in heat input, a decrease in the grain eccentricity was observed. The dependence of the hardness of the deposited metal on the surfacing mode was not noticed. The average value of hardness lies in the range of 66-68 HV. The results of the work are recommended to be used to select the pulse frequency (which also affects the droplet size) in the development of technologies for wire-arc additive manufacturing from aluminum alloys.

В ходе выполнения подводных работ возникают задачи увеличения времени выполнения операций автономными подводными аппаратами. С этой целью рассматривается использование плавучих платформ (судов катамаранного типа) для транспортировки, подбора и перезарядки автономных подводных аппаратов. При выполнении этой операции к плавучим станциям предъявляются высокие требования к измерительному комплексу, входящему в состав системы автоматического удержания, который должен обеспечивать заданную точность. Анализ показал, что качка судна существенно влияет на точность расчета горизонтальных перемещений. С этой целью в статье проводится анализ влияния бортовой качки судна на точность горизонтальных перемещений. Для реализации, поставленной задачи в работе построена упрощенная математическая модель горизонтальных смещений судна – платформы относительно подводного маяка в связанной с платформой системе координат, которые не учитывают качку платформы. Оценено влияние гидроакустических параметров на выбор сигнала буя – ориентира.

In the course of underwater work, the tasks of increasing the time for performing operations by autonomous underwater vehicles arise. For this purpose, the use of floating platforms (catamaran-type ships) for transportation, pickup and reloading of autonomous underwater vehicles is being considered. When performing this operation, floating stations are subject to high requirements for the measuring complex, which is part of the automatic holding system, which must provide the specified accuracy. The analysis showed that the ship's roll significantly affects the accuracy of the calculation of horizontal displacements. For this purpose, the article analyzes the influence of the ship's roll on the accuracy of horizontal movements. To implement the task in view, a simplified mathematical model of the horizontal displacements of the ship-platform relative to the underwater beacon in the coordinate system associated with the platform is constructed in the work, which do not take into account the rolling of the platform. The influence of hydroacoustic parameters on the choice of the buoy signal is estimated.
On Modelling of Standing Waves Considering the Stratification in the Baltic Sea
Authors: Руденко А.И.
Published: March 2023

Волновые процессы на поверхности океанических акваторий играют одну из главных ролей в формировании климата окружающей среды, рельефа морского дна и береговой зоны. Волны влияют на распределение энергетических потоков внутри водного континуума, который может быть стратифицирован по плотности, солености, температуре. Учет всех указанных характеристик одновременно весьма сложный, поэтому в данной работе учтена стратификация по плотности. Необходимо отметить, что в некоторых районах Балтийского моря можно выделить три слоя жидкости с различными плотностями. В статье рассмотрена задача о двумерных стационарных поверхностных и внутренних волнах в стратифицированной по плотности жидкости конечной глубины при условии, что волновые движения являются потенциальными. В рамках классической двумерной модели выделены три слоя стратифицированной жидкости. Найдены частоты колебаний установившихся волн в каждом стратифицированном слое. Определены кинетические энергии для каждого стратифицированного слоя. Обоснована генерация энергии при передачи направленного потока от слоя к слою жидкости.

Wave processes on the surface of oceanic waters play a major role in shaping the environmental climate, the relief of the seabed and the coastal zone. Waves affect the distribution of energy flows within the water continuum, which can be stratified by density, salinity, temperature. Taking into account all these characteristics at the same time is a very complex problem, therefore, stratification by density is taken into account in this work. It should be noted that in some areas of the Baltic Sea, three layers of liquid with different densities can be distinguished. The paper considers the problem of two-dimensional standing surface and internal waves in a density-stratified fluid of finite depth under the condition that the wave motions are potential. Within the framework of the classical two-dimensional model three layers of stratified fluid are identified. Oscillation frequencies of the standing waves are found in each stratified layer. Kinetic energy is estimated for each stratified layer. Energy generation during the transfer of the energy flow from one layer of the fluid to another has been substantiated.

The paper deals with the issues of determining the degree of danger of excessive convergence or determining the likelihood of a possible collision of ships in order to make an optimal decision or emergency measures. At the same time, the technology of using Fuzzy modeling using neural network technologies is constructive. The purpose of this article is to study the ship divergence model based on Fuzzy Logic and Neural network technologies, which ensures the adoption of optimal decisions on various aspects of navigation tasks. The formation of motion scenarios in this paper is considered when choosing a pair of ships, introducing interval estimates in the description of the ship's motion parameters, which allow taking into account the incompleteness or inaccuracy of the available information. On the basis of the constructed production model, based on the International Rules for the Prevention of Collisions at Sea and other regulatory documents, objects are related to various hazard categories and allow for a comprehensive assessment of the safety of the navigation situation.
Local Convergence of Parameter Based Derivative Free Continuation Method for the Solution of Non-linear Equations
Authors: Devi Kasmita , Maroju Prashanth
Published: March 2023

This paper's major purpose is to evaluate the local convergence of the parameter-based sixth- and seventh-order continuation iterative approach for solving nonlinear equations in R. This analysis assumes that the Fréchet derivative of the first order satisfies the Lipschitz continuity condition. Under these circumstances, we explore convergence analysis in order to investigate the existence and uniqueness region for the solution of our proposed strategies. Thus, we also offered the theoretical concept of the radii of convergence balls for the proposed approach. By determining the radii of the convergence balls and solving many numerical problems, we can verify the significance of our convergence study.

Tässä artikkelissa tarkoitukseni on pohtia suomalaissaksalaisia kulttuurisuhteita 1920-luvulta saksalaisen taidehistorioitsija Gustav Paulin (1866–1938) ja hänen toimiensa kautta. Pohdin muun muassa sitä, millainen vaikutus ja merkitys Paulin järjestämillä Ateneumin saksalaisen taiteen näyttelyllä lokakuussa 1922, Kalannin alttarikaapin osto- ja restaurointiaikeilla 1922–1925 sekä suunnitelmilla suomalaisesta taidenäyttelystä Saksassa 1926–1927 oli laajemmin Suomen ja Saksan välisille suhteille. Artikkelissa tarkastellaan ja analysoidaan Paulin ja suomalaisten välistä kirjeenvaihtoa, joissa käsitellään esimerkiksi saksalaisen taidenäyttelyn syntyprosessia ja siihen vaikuttaneita seikkoja, kuin myös Paulin mielikuvaa ja vaikutelmia vastaitsenäistyneestä Suomesta ulkomaalaisen silmin. Tarkoitukseni on osoittaa, miten Paulin toiminta Suomessa voidaan nähdä osana suomalaissaksalaisten suhteiden edistämistä ja positiivisen mielenlaadun osoittamista maalle, jolle suomalainen poliittinen eliitti koki olevansa kiitollisuuden velassa.

The paper examines the effect of records creation on service delivery among private higher institutions of learning. Although a number of studies have been carried out, most of them specifically focused on records management systems and the associated challenges and little attention is given to records management practices and its effect on service delivery with special reference to private higher institutions of learning. A cross sectional study design was adopted where both qualitative and quantitative approaches of data collection and analysis were used. A sample size of 83 respondents was used. Data was collected using both questionnaire survey and interview methods. Findings of the study revealed that records creation has a positive and significant influence on service delivery (p<0.01). The study concludes that service delivery does not rely solely on records creation implying that there are other factors that influence service delivery.

Published: March 2023

This paper sought feedback from Technical University Higher National Diploma (HND) Fashion Students on the adequacy of their preparations for their Semester-Out Industrial Attachment (S-OIA) programme. The paper adopted a cross-sectional descriptive survey design and used a semi-structured questionnaire to collect data from 199 third year HND Fashion Students from five public Technical Universities in Ghana. The feedback from the students showed varied levels of dissatisfaction about the school-based preparations they went through prior to the S-O IA programme. Even though majority of the students affirmed that the school-based preparations made were necessary, it was obviously not helpful to many in view of the percentage of respondents who were informed on the benefits of the programme during the school-based orientation. It was therefore suggested that Technical Universities Industrial Liaison offices adopt and strictly adhere to the school-based preparation protocols and processes.

Technogenic landscapes formed by coal mining are unique model sites for studying primary succession. We studied the formation of arthropod communities on rock dumps at coal mine dump sites of different ages and in natural environments. Using the pitfall traps, 5 classes of arthropods were found, with the domination of Insecta and Arachnida. The species composition for most of the studied groups of invertebrates was determined, the Berger-Parker dominance and Shannon species diversity indices were calculated. It has been established that the colonization of dumps depends not only on the age of recultivated lands, but also on habitat conditions (soil characteristics, vegetation parameters). At the beginning of the succession, dumps are massively populated by small-sized species that are tolerant of extreme conditions and have high dispersal abilities. Further development of vegetation entailed a change in the general structure of the ground-dwelling of arthropods communities. Discriminant analysis showed that the macrofauna of the compared sites differs statistically significantly in the space of discriminant functions. The areas at the foot of the dump and the natural biotope are characterized by the maximum differences; the greatest similarity was found between the young and old dumps. A significant contribution to the overall discrimination is made by the beetles of the families Geotrupidae, Staphylinidae, Elateridae, as well as centipedes (Chilopoda), and terrestrial bugs (Hemiptera). This study showed that communities of ground invertebrates are good indicators for monitoring the restoration of technogenically disturbed lands.

Islam hadir dapat menyesuaikan diri dengan kebudayaan masyarakat setempat. Pada masyarakat nusantara kebudayaan sebelum islam hadir ialah budaya animisme, dinamisme, agama Hindu serta Budha. Komunikasi antar budaya memandang bahwa masyarakat ialah bentuk dari hubungan yang terjadi baik aspek kecil hingga besar. Komunikasi antar budaya memandang bahwa adanya perbedaan kebiasaan antara budaya satu dengan yang lainnya. Dalam surat Al – Zalzalah ayat 7 – 8 menunjukkan bahwa firman Allah SWT terhadap perbuatan manusia sekecil apapun akan mendapatkan balasannya. Hal ini selaras dengan falsafah jawa yang berbunyi “becik ketitik ala ketara” bermakna “perbuatan baik dan perbuatan yang jelek suatu saat akan nampak dan ketahuan pada akhirnya”. Oleh karena itu penulisan ini bertujuan untuk menggabarkan bagaimana pesan dakwah dari hubungan budaya serta ajaran agama dalam surat Al Zalzalah serta dalam falsafah becik ketitik ala ketara. Hasil penulisan ini menunjukkan bahwa dalam berdakwah untuk memperhatikan etika komuinikasi budaya untuk dapat memahami strategi dakwah di masyarakat serta penyampaian makna yang dapat diterima masyarakat.
