Целью настоящей работы является системное исследование теплогидравлических процессов в гидравлическом тракте ядерного реактора с учетом влияния внешних динамических сил (качка, крен), присущих судовой ЯЭУ. Проведено экспериментальное исследование процессов неизотермического перемешивания и естественной циркуляции в одной и двух плоскостях колебаний. В качестве основного метода исследования были использованы экспериментальные методы (метод температурного зондирования), а также методы визуализации и системного анализа. Результатом применения такого системного подхода стала классификация задач, генерация новой системы, соотнесение и разграничение систем, ее составляющих, а также закономерности их функционирования, необходимость целенаправленного воздействия на введенную систему, а также новые системные связи. Показано, что система проточного тракта судовой ядерной энергетической установки является сложной нестационарной системой. Было получено, что действие статического крена и качки в одной плоскости сказывается сильнее и вызывает большие температурные градиенты вдоль области смешения потоков. В результате исследования процессов естественной циркуляции было получено, что качка в одной плоскости вызывает снижение массового расхода, что может негативно сказаться на теплотехнической надежности активной зоны.
The purpose of this work is a systematic study of thermohydraulic processes in the hydraulic path of a nuclear reactor, taking into account the influence of external dynamic forces (pitching, roll) inherent in the ship's nuclear power plant. An experimental study of the processes of non-isothermal mixing and natural circulation in one and two planes of oscillations has been carried out. Experimental methods (the method of temperature sensing), as well as visualization and system analysis methods were used as the main research method. The result of applying such a systematic approach was the classification of tasks, the generation of a new system, the correlation and differentiation of the systems that make up it, as well as the patterns of their functioning, the need for targeted impact on the introduced system, as well as new system connections. It is shown that the flow path system of a ship's nuclear power plant is a complex non-stationary system. It was found that the effect of static roll and pitching in the same plane has a stronger effect and causes large temperature gradients along the flow mixing region. As a result of the study of natural circulation processes, it was found that pitching in one plane causes a decrease in mass flow, which can negatively affect the thermal reliability of the active zone.

В статье утверждается, что экологическая безопасность судна определяется его герметичностью - основным фактором, влияющим на возможные экологические последствия в случае аварий и инцидентов. Указанный фактор является одной из характеристик свойств судна, включающих обеспечение плавучести, остойчивости, мореходности и прочности. Рассмотрена связь этих характеристик с герметичностью корпуса и их влияние на экологическую обстановку. Для оценки экологической безопасности судна в функции сохранения его целостности предлагается использовать метод парных сравнений по определению коэффициентов важности различных факторов, а также аддитивную свёртку обобщённой функции технической полезности (эффективности). Сформулированы преимущества метода парных сравнений при определении коэффициента важности характеристик, который упрощает принятие решения по предпочтению определённых целей или показателей. Показано, что одним из наиболее удобных способов построения функции полезности является обобщенная функция желательности Харрингтона. В рамках оценки влияния свойств судна на экологическую безопасность подтверждена целесообразность использования показателя технической полезности в табличной форме функции Харрингтона, в аналитическом виде – в форме функции желательности Харрингтона с отрицательным градиентом и в форме релейной функции технической полезности.
The article states that the environmental safety of a vessel is determined by its tightness - the main factor affecting the possible environmental consequences in the event of accidents and incidents. This factor is one of the characteristics of the ship's properties, including ensuring buoyancy, stability, seaworthiness and strength. The connection of these characteristics with the tightness of the housing and their impact on the environmental situation is considered. To assess the environmental safety of a vessel in the function of preserving its integrity, it is proposed to use the method of paired comparisons to determine the coefficients of importance of various factors, as well as an additive convolution of the generalized function of technical utility (efficiency). The advantages of the method of paired comparisons in determining the coefficient of importance of characteristics, which simplifies the decision-making on the preference of certain goals or indicators, are formulated. It is shown that one of the most convenient ways to construct the utility function is the generalized Harrington desirability function. As part of the assessment of the impact of the ship's properties on environmental safety, the expediency of using the technical utility indicator in tabular form of the Harrington function, in analytical form – in the form of the Harrington desirability function with a negative gradient and in the form of a relay function of technical utility was confirmed.

Published: June 2022

В работе обсуждаются вопросы, связанные с автоматизацией процесса судовождения в рамках реализации элементов концепции безэкипажного судовождения. Рассмотрена реализация этапов процесса подготовки судна к швартовке в автоматическом режиме судов нового типа, оснащенных колесным движительно-рулевым комплексом. Особое внимание уделено торможению судна, т.е. снижению скорости до приемлемого уровня и выходу его в заранее заданную область. В дальнейшем производится ориентация корпуса судна относительно причальной стенки и перемещение к ней лагом. Маневры выполняются за счет изменения направления вращения и соотношения частот вращения гребных колес. Существенное влияние на динамические характеристики судна при выполнении этого маневра оказывают внешние воздействия. В работе изучено влияние ветра на динамику судна в процессе торможения при реализации предложенного алгоритма управления движительным комплексом судна. Получены аналитические выражения для вычисления поправочного коэффициента для алгоритма управления, обеспечивающего остановку судна в заданной точке в зависимости от силы и направления кажущегося ветра, а также начальной скорости движения судна. Предложенные подходы позволяют реализовать автоматическую швартовку колесных судов.
The paper represents the issues related to automation of the navigation process within the framework of implementing the elements of the unmanned navigation concept. The authors consider the preparation stages of new-type vessels equipped with wheeled propulsion/steering system for mooring in automatic mode. Particular attention is paid to vessel braking, i.e. reducing the speed to an acceptable level and going into a predetermined area. Then the vessel's hull is oriented relative to the quay wall and moves towards it with a lag. The maneuvers are performed by changing the direction of rotation and the ratio of rotation frequencies of the paddle wheels. External influences exert a significant impact on the dynamic characteristics of the vessel when performing this maneuver. The paper studies the effect of wind on the dynamics of a ship during braking while implementing the proposed control algorithm for the propulsion system of the ship. Analytical expressions for calculating the correction factor for the control algorithm are obtained. The algorithm ensures the stopping of the ship at a given point, depending on the strength and direction of the apparent wind, as well as the initial speed of the ship. The proposed approaches make it possible to implement automatic mooring of wheeled vessels.

В начальной стадии выполнения любого маневра необходимо прогнозирование движения судна в текущих условиях плавания до момента совершения судоводителем через средства управления судном определенных управляющих воздействий. Как правило, такое прогнозирование основывается на практическом опыте судоводителя, осуществляющего управление или дающего команды на выполнение управляющего воздействия. В данном случае не исключена ошибка, вероятность которой существенно возрастает, если условия, в которых выполняется маневр не адекватны практическому опыту судоводителя. В лучшем случае, оценку правильности выполняемых действий он осуществляет последовательно, методом проб и ошибок. Относительная скоротечность выполнения любой сложной операции по маневрированию судна не представляет судоводителю достаточно времени для анализа степени и характера влияния множества факторов на поведение судна. В этих условиях целесообразно использовать возможность бортового компьютера. Для этого необходимо, прежде всего, иметь в памяти компьютера базовую математическую модель судна (возможно несколько моделей разного вида), программу идентификации математической модели с привязкой к текущим условиям плавания и состоянию загрузки судна на данный момент, а также алгоритм и разработанные на его основе программные средства для выполнения прогноза движения судна. Решению этих задач посвящена настоящая статья.
At the initial stage of performing any maneuver, it is necessary to predict the movement of the vessel in the current sailing conditions until the moment the navigator makes certain control actions through the means of control of the vessel. As a rule, such forecasting is based on the practical experience of the navigator performing control or giving the command to perform control action. In this case, an error is not excluded, the probability of which increases significantly if the conditions in which the maneuver is performed are not adequate to the navigator's practical experience. At best, he evaluates the correctness of the actions performed sequentially, by trial and error. The relative transience of any complex ship maneuvering operation does not provide the navigator with enough time to analyze the degree and nature of the influence of many factors on the ship's behavior. In these conditions, it is advisable to use the capability of the on-board computer. To do this, it is necessary, first of all, to have in the computer memory the basic mathematical model of the ship (several models of different types are possible), the program for identifying the mathematical model with reference to the current sailing conditions and the state of loading of the ship at the moment, as well as an algorithm and software developed on its basis. means for forecasting the movement of the vessel. This article is devoted to solving these problems.

Authors: Rahmi Messia Refri , Rahman Ardizal 
Published: June 2022

Background: Orbital lymphoma is found in 50-60% of ocular adnexal lymphomas, with approximately 90% of orbital lymphomas being Non-Hodgkin's lymphomas. Clinical features may include proptosis, ptosis, limitation of eye movement, and salmon patch lesions on the conjunctiva. If an orbital tumor is present, an accurate histopathological examination is important in the management of orbital lymphoma. Because of nonspecific clinical signs and symptoms, some diagnostic delays may occur. The purpose of the study was to evaluate the clinical features, diagnostic approach, and treatment choice in orbital lymphomas.
Methods: We identified patients diagnosed with orbital lymphoma in an outpatient clinic in Dr. M. Djamil General Hospital from January to December 2018. Patients’ medical records were reviewed retrospectively.
Results: The patient group consisted of 6 patients (five males and one female) with a median age of 58 years. Proptosis and orbital swelling were the leading clinical symptoms, mainly found unilateral (five cases). The diagnosis was confirmed by a surgical biopsy. One histology result showed lymph node hyperplasia, which didn't suit the clinical manifestation and got re-reviewed. All histology results then showed non-Hodgkin’s lymphoma with the small lymphocytic type (100%). Five patients received systemic chemotherapy with the CHOP regimen protocol, and one patient refused to get further chemotherapy treatment.
Conclusion: When unmatched orbital symptoms with histology results are present, re-reviewing the histology result is essential. Once the diagnosis is established, systemic chemotherapy is indicated and can proceed so there will be no delay in treatment
