В статье приводится решение задачи по подтверждению адекватности математической модели, разработанной для исследования динамики роторов на газовых опорах. Газовые подшипниковые опоры имеют многочисленные преимущества перед гидродинамическими подшипниками, работающими на масле. В их число входит повышение механического КПД, повышение надёжности агрегата (ввиду отсутствия системы смазки) и многие другие. Однако газовые опоры имеют повышенные требования к точности изготовления подшипниковых узлов, что усложняет выполнение виброналадки роторов судовых турбогенераторов на таких опорах. В связи с этим, данное исследование направлено на повышение точности определения критических частот роторов турбогенераторов на податливых газовых опорах при проектировании. Для того, чтобы подтвердить адекватность результатов, получаемых с помощью математической модели ротора на податливых газовых опорах, был проведён эксперимент на лабораторной установке. Была получена зависимость первой критической частоты исследуемого ротора от давления наддува в подшипниках для реальной системы. Приведено сравнение результатов физического эксперимента и результатов расчёта при помощи математической модели..

The article provides a solution to the problem of confirming the adequacy of a mathematical model developed to study the dynamics of rotors on gas supports. Gas bearings have many advantages over hydrodynamic bearings running on oil. These include an increase in mechanical efficiency, an increase in the reliability of the unit (due to the lack of a lubrication system) and many others. However, gas supports have increased requirements for the accuracy of manufacturing bearing assemblies, which complicates the implementation of vibration adjustment of the rotors of marine turbogenerators on such supports. In this regard, this study is aimed at improving the accuracy of determining the critical frequencies of turbogenerator rotors on malleable gas supports during design. In order to confirm the adequacy of the results obtained using a mathematical model of a rotor on malleable gas supports, an experiment was carried out on a laboratory installation. The Article provides with obtained dependence of the first critical frequency of the studied rotor on the boost pressure in the bearings for a real system and a comparison of the results of a physical experiment and the results of calculation using a mathematical model. Keywords: Rotordynamics, critical frequencies, gas bearings

Для снижения концентрации вредных газовых выбросов и аэрозолей судовых дизелей предлагается использование жидкостной нейтрализации. В процессе нейтрализации организовано пленочное течение жидкости по вертикальным пластинам. При движении выхлопных газов или загрязненного воздуха между пластинами пленка жидкости как абсорбент интенсивно поглощает газообразные и твердые загрязняющие вещества. На экспериментальном стенде проведено исследование интенсивности абсорбции в пленку воды углекислого газа. В экспериментах изменялись скорость газа, расход жидкости, концентрация вредных веществ в газе. В результате анализа полученных результатов выявлена оптимальная скорость газа, оптимальное значение орошения. При этом концентрацию двуокиси углерода возможно снизить на 30-45 % на длине контакта 0,6-1 м. Обобщение полученных результатов в широком диапазоне изменения концентраций газа, расходов жидкости и скорости движения загрязненного газа получено в виде зависимости между критериями Нуссельта, Рейнольдса и Прандтля.

To reduce the concentration of harmful gas emissions and aerosols of marine diesel engines, the use of liquid neutralization is proposed. In the process of neutralization, a film flow of liquid over vertical plates is organized. When exhaust gases or polluted air move between the plates, the liquid film as an absorbent intensively absorbs gaseous and solid pollutants. On the experimental bench, the intensity of carbon dioxide absorption into the water film was studied. In the experiments, the gas velocity, liquid flow rate, and the concentration of harmful substances in the gas were changed. As a result of the analysis of the obtained results, the optimal gas velocity and the optimal irrigation value were revealed. At the same time, the concentration of carbon dioxide can be reduced by 30-45% at a contact length of 0.6-1 m. The generalization of the results obtained in a wide range of changes in gas concentrations, liquid flow rates, and the rate of movement of polluted gas is made in the form of a criterion dependence between the Nusselt, Reynolds and Prandtl criteria.

Probability function of detection for signal detector with level and time thresholds
Authors: Егоров С.Б. , Горбачев Р.И.
Published: March 2023

Рассматривается автоматический обнаружитель шумового сигнала движущегося источника шумоизлучения, работающий непрерывно во времени и переходящий в режим обнаружения, когда источник входит в телесный угол главного максимума характеристики направленности (ХН) приемной антенны. Обнаружитель содержит индикаторное устройство, состоящее из двух последовательно включенных селекторов сигнала: первого – по уровню, второго – по длительности. Вероятностная характеристика обнаружения сигнала для такого обнаружителя определена на конечном интервале времени, «привязанном» к моменту прохождения источником максимума ХН. При получении вероятностной характеристики обнаружения использованы вероятностные характеристики суммарного (сигнально-помехового) индикаторного процесса на конечном интервале времени, а также «выбросовая» трактовка работы обнаружителя на конечном интервале времени. Формула вероятностной характеристики получена и проанализирована для нормализованного суммарного индикаторного процесса. При важных для практики условиях предложены простые соотношения для определения порогового значения индикаторного отношения сигнал/помеха.

This article considers an automatic detector of a noise signal from a moving source, which operates continuously in time and switches to the detection mode when the source enters to the solid angle of the main directivity beam of the receiver’s antenna. The detector contains an indicator block consisting of two signal selectors connected one after another: the first one by level, the second one by time. The probability function of signal detection for such detector is determined on a finite time interval relative to the moment when the signal source passes the main beam. To obtain the probability function of detection, we used the probability function of the summary (signal plus noise) indicator process on a finite time interval. This model is inherited from our previous publications and known as the “emissional” interpretation of the detector’s operation on a finite time interval. The equation for the probability function of signal detection is obtained and analyzed for the normalized summary indicator process. According to conditions important for practice, simple relationships are proposed to determine the threshold value of the indicator signal-to-noise ratio.

Статья посвящена теме оценки времени присутствия автономного необитаемого подводного аппарата (АНПА) в положении, ограниченном заданным углом курса на примере управления АНПА при передаче данных в морской среде из АНПА на фиксированную платформу с помощью лазерного приёмо-передатчика. Цель статьи: осуществить качественный прогноз времени пребывания АНПА в заданном положении при действии внешних возмущающих факторов, что должно приводить к более эффективному использованию ограниченных ресурсов АНПА при передаче данных. Новизна заключается в использовании в алгоритмах прогноза нескольких а-профилей, содержащих траектории наиболее вероятного движения к заданным ограничениям и оценки времени движения вдоль них. Для решения задач используются методы теории больших уклонений, методы Монте-Карло, методы численного интегрирования дифференциальных уравнения. Траектории наиболее вероятного движения вычисляются аналитически. В статье приводятся результаты численного симулирования управления курсом АНПА MiddleAUV на приёмное устройство при действии внешних возмущений; оценки времени присутствия в заданных ограничениях курса соответствующие каждому моменту времени до выхода за ограничения; статистические метрики ошибок прогноза, которые свидетельствуют о достаточном качестве прогноза. Для 5 сек окна прогноза максимальная абсолютная ошибка составляет не более 0.5 сек.

The article is devoted to the topic of estimating the presence time problem of an autonomous underwater vehicle (AUV) in a position limited by a given course angle. Methods described using the example of AUV control in the process of transmitting data in the marine environment from AUV to a fixed platform using a laser transceiver. The purpose of the article: to carry out a qualitative forecast of the time spent by the AUV in a given position under the action of external disturbing factors, which should lead to a more efficient use of the limited resources of the AUV when transmitting data. The novelty lies in the use of several a-profiles in prediction algorithms containing trajectories of the most probable movement to the specified constraints and estimates of the time of movement along them. Methods of the theory of large deviations, Monte Carlo methods, methods of numerical integration of differential equations are used to solve problems. The trajectories of the most probable movement are calculated analytically. The article presents the results of numerical simulation of the control of the AUV, named MiddleAUV, course on the receiving device under the action of external disturbances; estimates of the presence time in the specified limits of the course corresponding to each moment of time before going beyond the limits; statistical metrics of forecast errors, which indicate the sufficient quality of the forecast. For 5 seconds of the forecast window, the maximum absolute error is less than 0.5 seconds.
Analytical simulation model of a query system

Published: March 2023

В практике технологического проектирования морских торговых портов расчетно-аналитические методы, оперирующие с детерминированными величинами, часто оказываются недостаточными. В ряде случаев искомое расширение может быть получено за счёт привлечения методов статистического моделирования (методов группы Монте-Карло), в иных случаях решение дают методы теории массового обслуживания. Использование канонических формул теории массового обслуживания осложняется весьма жесткими ограничениями на характер входного потока и параметры моделируемой системы. Более адекватным расширением является использование имитационного симуляционного моделирования, в частности, объектно-ориентированного. В то же время имитационное симуляционное моделирование, хотя и является более адекватным приближением, но в реализации оказывается существенно более трудоемкой и узкоспециализированной методикой, поскольку соответствующие модели создаются «ad hoc», т. е. адекватными конкретному объекту в конкретных условиях. В данной работе предпринято попытка найти достаточно простое и в то же время универсальное решение, которое может быть использовано для широкого круга задач технологического моделирования разнообразных транспортных объектов и процессов.

In the practice of technological design of seaports, the analytical methods that use deterministic values often occur to be incorrect. In certain cases, the result could be precise with utilization of statistical modelling methods such as Monte-Carlo method. In other cases, the correct result could be gained with implementation of query theory methods. The traditional formulas of query theory are inconvenient as it sets certain requirements to the incoming flow and system’s parameters. The more adequate decision is to use agent-based simulation modelling. At the same time this method requires more labor to implement it as these models are made “ad hoc”, i.e., adequate to a certain object in certain circumstances. The article is dedicated to try to find the most simple and universal method of different transportation systems’ technological modelling.

Warum neue transatlantische Lektüren Thomas Manns? Eine Antwort auf diese Frage findet sich in einer Rede, die Bundespräsident Frank-Walter Steinmeier am 19. Juni 2018 anlässlich der Eröffnung des neu gegründeten Thomas Mann House in Los Angeles
gehalten hat. Thomas Mann als vom transatlantischen Austausch geprägten Denker zu begreifen, so argumentiert Steinmeier dort, bedeutet gleichzeitig, eine neue Perspektive auf sich selbst zu gewinnen. Denn es war die Auseinandersetzung mit einem amerikanischen Dichter, Walt Whitman, die
Mann zum ersten Mal die Notwendigkeit demokratischer Reformen in Deutschland verdeutlichte, und es war die Begegnung mit einem amerikanischen Politiker, Franklin D. Roosevelt, die seinen Wandel vom Vernunft- zum Gesinnungsrepublikaner herbeiführte.1
Verkörperung des Intermediären.Überlegungen zu Thomas Manns amerikanischer Vortragskunst
Authors: Seebeck Roman
Published: March 2023

Abstract Thomas Mann wurde in den Vereinigten Staaten innerhalb kürzester Zeit zum gefeierten public intellectual. Ein zentrales und bisher kaum untersuchtes Element des Amerikaner-Werdens des Autors war sein Engagement als Redner auf dem lecture circuit,
einer institutionell und gesellschaftlich fundierten genuinen amerikanischen Vortragskultur. In meinem Beitrag argumentiere ich, dass Thomas Manns Agieren auf den Vortragsbühnen des Landes einerseits als Medium des Autors zur kulturellen Annäherung an die Vereinigten Staaten diente
und andererseits entschieden dazu beitrug, dass Thomas Mann zu einer gewichtigen Stimme im transatlantischen Diskurs der Kriegsjahre werden konnte.
Die Welten der Manns
Authors: Fuechtner Veronika
Published: March 2023

Abstract ,,Die Welten der Manns“ zeichnet die öffentliche Faszination für die Familienbiografie der Manns und ihre politische Relevanz über die Jahrzehnte hinweg nach. Die Manns selbst bastelten schon an einer Familienfiktion, die ihr Leben und ihre Literatur
als exemplarisch deutsch positionieren sollte. Doch die vielen Migrationen in dieser Familienbiografie, und auch die Weise, in der die Manns im Ausland gelesen werden, zeigen, wie sehr diese Familie auch in anderen Heimaten und Sprachen lebte und schrieb und ihnen letztlich auch heute noch
zugehört.
Joseph in America
Authors: Kontje Todd
Published: March 2023

Abstract This short essay focuses on the most “American” of Mann’s novels in the larger context of his fictional universe. Joseph der Ernährer offers an oblique response to Nazi Germany refracted through the lens of ancient Egypt, but it also
reflects Mann’s ongoing engagement with the meaning of America. Mann creates a comic counterpart to historical tragedy, granting humanity a vision of redemption in an utterly debased world. The laudable cosmopolitanism of Mann’s world view unfortunately goes hand in hand with a
less admirable tendency to project racial difference and sexual desires onto “dark” continents in his literary works.
The Question of Why. Der Zauberberg and the Meaning of Life.An Essay
Authors: Jensen Morten Høi
Published: March 2023

Abstract This essay examines why ordinary readers, even a hundred years after its publication, are still drawn to Der Zauberberg not just for its formal appeal, but also for its revelatory potential, its promise of holding deep significance. The “novel of ideas”
has been repeatedly discredited throughout the twentieth century, and Thomas Mann has sometimes been discredited as a fusty practitioner of the genre. Yet something about Der Zauberberg seems to transcend the limitations of this form.
Haaksirikkoja ja riskinhallintaa 1700-luvun Suomenlahdella
Authors: Huhtamies Mikko
Published: March 2023

Artikkeli tarkastelee haaksirikkoja 1700-luvun Suomenlahdella pääasiassa Helsingin kaupunginarkistossa säilytettävien ja kapteenien antamien meriselitysten perusteella. Muina lähteinä on käytetty ns. sukellusraportteja, huutokauppapöytäkirjoja ja karttoja. Vuonna 1703 perustetun Pietarin jälkeen laivaliikenne Suomenlahdella kasvoi merkittävästi, ja vuosisadan lopulla idän suuntaan meni jo noin tuhat laivaa vuodessa. Haaksirikoilta ei vältytty. Heikkoja tulimajakoita oli vain muutama ja nekin Hiidenmaan Kõpua lukuun ottamatta itäisellä Suomenlahdella. Merenkulun historiassa riskiä on yritetty hallita monin keinoin. Periaatteena on ollut keskiajalta lähtien sen jakaminen eri tavoin. Alusten omistuksen ohella purjepinta-alaa alettiin jakaa 1450-luvulla useammalle mastolle. Haaksirikoista suurin osa sattui syksyllä, kun oli pimeää ja tuulista. Laivat joutuivat vastatuuleen luoviessaan vaikeuksiin ja ajoivat karille Suomenlahden uloimpien kivien kohdalla. Usein laivat joutuivat palaamaan takaisin pitkiä matkoja jopa lähtösatamaan. Haaksirikon jälkeen paikalle tullut sukelluskomppania lievensi toteutuneen riskin seurauksia ja oli näin samalla eräänlainen riskinottokynnystä alentava vakuutus. Kartat ja navigointivälineet kehittyivät 1700-luvun kuluessa. Riskiä pystyttiin vähentämään, mutta ylivoimaisille luonnonvoimille tai pimeydelle ei voitu mitään. Vasta viivasuoraan konevoimalla liikkuneet höyryaluksen lisäsivät vähitellen meriturvallisuutta. Höyrylaivoissakin oli kuitenkin vielä pitkään purjeet kaiken varalta.
 
The article focuses on 18th century shipwrecks and risk management in the Gulf of Finland using sea protest (maritime declarations) as its primary sources. These documents, given by captains at the Magistrates court, are held in the Helsinki City Archives. Secondary sources are the diving reports, court records, auction protocols, and sea charts. The passage to St Petersburg (est. 1703) in the Gulf of Finland can be considered one of the most important crossroads of international shipping in the 18th century. The increase in the volume of shipping led to several shipwrecks per year. The level of infrastructure concerning sea safety was low, e.g there were very few lighthouses. Risk management was based on dividing up the ownership of the ship as well as increasing the number of masts (from one to three) and sails. Most shipwrecks took place in autumn when it was dark and stormy. Sailing close to a strong wind caused difficulties for captains and ships. When tacking many ships became stranded on the outermost skerries of the Finnish archipelago. Charts and navigational instruments improved during this century, but it was not until the arrival of steamships that sea safety significantly improved. However, even steamers had sails in the beginning   – just in case.

Suomalaiset siirtolaiset Pohjois-Amerikassa: Valokuvat ja empatia siltana nykyisyyteen
Authors: Matila Tuuli
Published: March 2023

Tarkastelen tässä artikkelissa suomalaisten siirtolaisten elämää Michiganin ”Copper Countryn” alueella Pohjois-Amerikassa 1900-luvun alkuvuosikymmeninä. Arkistovalo-kuvat valottavat suomalaissiirtolaisten kokemuksia vieraassa maassa ja sitä, kuinka he ilmaisivat identiteettiään alueella. Käytetty teoria, proteesinen muisti, korostaa ensinnäkin teknologian, tässä tapauksessa valokuvien, tärkeyttä integraation välineenä. Toisaalta pro-teesinen muisti korostaa nykypäivänä teknologian, kuten juuri valokuvien, tärkeyttä työka-luna: valokuvat välittävät menneisyydestä tietoa empatiaa herättävällä tavalla. Siirto-laisuudessa on tiettyjä yleismaailmallisia piirteitä, joita esiintuomalla voitaisiin herättää hyödyllistä keskustelua tästä poliittisesti painavasta aiheesta. Empatian kautta voitaisiin luoda yhteyksiä myös nykysiirtolaisuuteen ja ymmärryksen lisäämiseen maahantulijoita kohtaan.
Rentoja rekiviisuja ja kauniita kansallislauluja
Authors: Kuismin Anna
Published: March 2023

Artikkelissa analysoidaan seuranäytelmiä, joita ajan kielenkäytössä kutsuttiin laulunsekaisiksi kansannäytelmiksi. Aineisto koostuu lähes kolmestakymmenestä suomenkielisestä teatterikappaleesta, jotka ovat ilmestyneet vuosien 1885 ja 1914 välisenä aikana. Varsinkin lyhyiden teatterikappaleiden kohdalla kysymys oli käyttökirjallisuudesta, jonka suhteen tekijöillä ei ollut suuria taiteellisia tavoitteita. Samantapaiset juonet, henkilöasetelmat ja laulut toistuvat tekstistä toiseen. Vaikka lehdistössä kritisoitiin suulliseen kulttuuriin kuuluneita, erityisesti nuorison suosimia rekilauluja, niillä oli näytelmissä useita funktioita. Laulujen avulla karakterisoitiin henkilöhahmoja, ilmaistiin tunteita ja kuvattiin nuorten seurustelukulttuuria. Artikkelin keskiössä on ”laulusekaisten kansannäytelmien” historiallisten, kulttuuristen ja sosiaalisten kontekstien tarkastelu. Osa teksteistä sisältää isänmaata ja kotiseutua ylistäviä lauluja, mikä kertoo tekstien lomittumisesta kansanvalistuksen ja kansakunnan rakentamisen projekteihin.

1930-luvulla suomen- ja ruotsinkielisten välinen kielikiista saavutti huippunsa. Samalla vuosikymmenellä kielikiistassa ajauduttiin myös väkivallankäyttöön. Tämä tapahtui vuosina 1933–1937 Helsingin keskustassa ruotsalaisuuden päivän yhteydessä syntyneissä mellakoissa. Artikkelissa kuvataan, mitä sanomalehdet mellakoista kirjoittivat. Erosivatko lehtien näkemykset mellakoiden syyllisistä ja miten? Artikkelin pääaineistona on käytetty Kansalliskirjaston digitoituja sanomalehtiä 1930-luvulta. Vaikka 1930-luvun kielitaistelusta on kirjoitettu lukuisia teoksia, tässä artikkelissa keskitytään ensimmäistä kertaa systemaattisesti juuri ruotsalaisuuden päivänä Helsingissä tapahtuneisiin mellakoihin ja siihen, kuinka suomalainen lehdistö niihin reagoi.

Published: March 2023

The paper intended to look for more convenient technology to produce a signage that will create awareness of the new Akatakyi campus of the Takoradi Technical University and also provide functional and efficient direction to people. The research specifically sought to identify suitable landmarks and locations for mounting specific types of signage and directional signs for effective communication at the Akatakyi campus of the Takoradi Technical University. The vibrant growth of the university and the increasing number of the students over the past years has therefore rendered the Effia campus congested hence overstretching the facilities for the university. As a result, the management has acquired one hundred and fifty acres of land for the expansion of the university at the Akatakyi-Ahanta community a suburb of Takoradi to ease congestion on the main campus. The newly Akatakyi campus is intended to accommodate the Faculty of Engineering. It has been observed that most people are not familiar with the location and the program intended to be run at the Akatakyi campus of the university. It is therefore imperative to find ways of creating awareness of the new campus. The descriptive research method was used in the study to identify, describe and document all the data collected. The instruments used in gathering data were conversation, observation and interview. The outcome shows an excellent procedural model with illustrations. It is recommended that the management of Takoradi Technical University management should engaged the researcher and finance this project for the execution of the actual and the standardized sizes. This will help visitors all day to reduce stress hence, to located TTU facilities at ease within Akatakyi campus.
Tindak Pidana Perpajakan Dalam Pelaporan Surat Pemberitahuan Tahunan Pajak Menurut Undang-Undang Ketentuan Umum dan Tata Cara Perpajakan
Authors: Joka M. Rikhardus
Published: March 2023

Tindak pidana perpajakan merupakan perbuatan yang dilarang oleh Undang-Undang Perpajakan di Indonesia. Ketentuan tersebut telah diatur dalam Pasal 38, 39, 39A, 41, 41A, 41B,41C, 43A, 44 dan 44B UU No. 28 Tahun 2007 tentang Ketentuan Umum dan Tata Cara Perpajakan yang telah mengubah UU No. 6 Tahun 1983 dan perubahan terakhir dengan UU No. 7 Tahun 2021 tentang Harmonisasi Peraturan Perpajakan. Bentuk-bentuk tindak pidana perpajakan yang dilakukan oleh pelaku tindak pidana pajak seperti perbuatan pelanggaran hukum dengan bersikap pasif tidak ingin melaporkan Surat Pemberitahuan Tahunan (SPT) pajak dengan maksud untuk tidak membayar pajak (tax offences), penggelapan pajak (tax evasion) dan perbuatan pelanggaran hukum pajak dengan memanfaatkan kelemahan undang-undang pajak (tax avoidance). Faktor penyebab timbulnya tindak pidana perpajakan adalah pembayaran pajak dianggap beban, ketidakpercayaan wajib pajak terhadap pengelolaan pajak, tingginya tarif pajak, kurang sosialisasi atas peraturan pajak, lemahnya pengawasan dan terlalu rendah sanksi hukum peraturan perpajakan. Kasus tindak pidana perpajakan di Indonesia setiap tahun kecenderungan meningkat, terbukti dari laporan tahunan PPATK (Pusat Pelaporan dan Analisis Transaksi Keuangan) menyatakan bahwa 5 (lima) tahun terakhir sejak tahun 2016 hingga 2021 meningkat 47,3%. Data kenaikan tindak pidana perpajakan tersebut menunjukkan bahwa upaya penegakan hukum dalam tindak pidana perpajakan belum maksimal. Keadaan inilah menyebabkan negara setiap tahun tidak mencapai target dalam penerimaan pajak. Sedangkan upaya yang dilakukan oleh Direktur Jenderal Pajak dalam mencegah tindak pidana perpajakan juga hanya dengan cara preemptif yaitu menanamkan nilai-nilai atau norma-norma agama yang baik terhadap diri wajib pajak dengan tujuan agar nilai-nilai tersebut dapat terinternalisasi dalam pekerjaan sehari-hari. Upaya lanjutan dengan upaya preventif yaitu dengan melakukan penyuluhan terhadap masyarakat wajib pajak untuk mengetahui dan memahami kewajiban dalam membayar pajak dan sanksi hukum apabila melanggar tindak pidana perpajakan.

Abstract

The purpose of the research is to analyse the poem Fī ‘Ainaiki ‘Unwānī by Fārūq Juwaidah using structural-semiotic analysis study. The research method used is a qualitative-descriptive method with content analysis approach. The result of this research shows that the meaning in this poem is still spread and implied at the heuristic level. However, this poem indicates an idea of the feeling expressed from the two sides of woman and man lovers at the hermeneutic level. On one side, a woman feels concerned about his affection and doubts it. On another side, a man is promising an eternal love for her to answer her worries. Furthermore, structural analysis shows that this poem contains a lot of tasybīh that strengthens the lines with the theme of affection written by Fārūq Juwaidah in this poem.

Keywords: Fārūq Juwaidah, Fī ‘Ainaiki ‘Unwānī, Structural-Semiotics.
