Updating the Data on Malaria Vectors in Malaysia: Protocol for a Scoping Review
Authors: Ali Rafidah , Wan Mohamad Ali Wan Najdah , Wilson Putit Perada
Published: October 2022

Background

Malaria is still a public health threat. From 2015 to 2021, a total of 23,214 malaria cases were recorded in Malaysia. Thus, effective intervention and key entomological information are vital for interrupting or preventing malaria transmission. Therefore, the availability of malaria vector information is desperately needed.

Objective

The objective of our study is to update the list of human and zoonotic malaria vectors in Malaysia. This work will include (1) the characterization of the key behavioral traits and breeding sites of malaria vectors and (2) the determination of new and potential malaria vectors in Malaysia. The findings of our scoping review will serve as decision-making evidence that stakeholders and decision makers can use to strengthen and intensify malaria surveillance in Malaysia.

Methods

The scoping review will be conducted based on the following four electronic databases: Scopus, PubMed, Google Scholar, and Science Direct. A search strategy was conducted for articles published from database inception to March 2022. The criteria for article inclusion were any malaria vector–related studies conducted in Malaysia (with no time frame restrictions) and peer-reviewed studies. The PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) will be used to guide our systematic approach. Data from published research literature will be extracted by using a standardized data extraction framework, including the titles, abstracts, characteristics, and main findings of the included studies. To assess the risk of bias, articles will be screened independently by 2 reviewers, and a third reviewer will make the final decision if disagreements occur.

Results

The study commenced in June 2021, and it is planned to be completed at end of 2022. As of early 2022, we identified 631 articles. After accessing and evaluating the articles, 48 were found to be eligible. Full-text screening will be conducted in mid-2022. The results of the scoping review will be published as an open-access article in a peer-reviewed journal.

Conclusions

Our novel scoping review of malaria vectors in Malaysia will provide a comprehensive evidence summary of updated, relevant information. An understanding of the status of Anopheles as malaria vectors and the knowledge generated from the behavioral characteristics of malaria vectors are the key components in making effective interventions for eliminating malaria.

The Feasibility and Acceptability of an mHealth Conversational Agent Designed to Support HIV Self-testing in South Africa: Cross-sectional Study
Authors: Ntinga Xolani , Musiello Franco , Keter Alfred Kipyegon , Barnabas Ruanne , van Heerden Alastair
Published: October 2022

Background

HIV testing rates in sub-Saharan Africa remain below the targeted threshold, and primary care facilities struggle to provide adequate services. Innovative approaches that leverage digital technologies could improve HIV testing and access to treatment.

Objective

This study aimed to examine the feasibility and acceptability of Nolwazi_bot. It is an isiZulu-speaking conversational agent designed to support HIV self-testing (HIVST) in KwaZulu-Natal, South Africa.

Methods

Nolwazi_bot was designed with 4 different personalities that users could choose when selecting a counselor for their HIVST session. We recruited a convenience sample of 120 consenting adults and invited them to undertake an HIV self-test facilitated by the Nolwazi_bot. After testing, participants completed an interviewer-led posttest structured survey to assess their experience with the chatbot-supported HIVST.

Results

Participants (N=120) ranged in age from 18 to 47 years, with half of them being men (61/120, 50.8%). Of the 120 participants, 111 (92.5%) had tested with a human counselor more than once. Of the 120 participants, 45 (37.5%) chose to be counseled by the female Nolwazi_bot personality aged between 18 and 25 years. Approximately one-fifth (21/120, 17.5%) of the participants who underwent an HIV self-test guided by the chatbot tested positive. Most participants (95/120, 79.2%) indicated that their HIV testing experience with a chatbot was much better than that with a human counselor. Many participants (93/120, 77.5%) reported that they felt as if they were talking to a real person, stating that the response tone and word choice of Nolwazi_bot reminded them of how they speak in daily conversations.

Conclusions

The study provides insights into the potential of digital technology interventions to support HIVST in low-income and middle-income countries. Although we wait to see the full benefits of mobile health, technological interventions including conversational agents or chatbots provide us with an excellent opportunity to improve HIVST by addressing the barriers associated with clinic-based HIV testing.
The Agreement Between Virtual Patient and Unannounced Standardized Patient Assessments in Evaluating Primary Health Care Quality: Multicenter, Cross-sectional Pilot Study in 7 Provinces of China
Authors: Zeng Minrui , Cai Yiyuan , Cao Jin , He Qianyu , Wang Xiaohui , Lu Yun , Liang Huijuan , Xu Dong , Liao Jing
Published: October 2022

Background

The unannounced standardized patient (USP) is the gold standard for primary health care (PHC) quality assessment but has many restrictions associated with high human and resource costs. Virtual patient (VP) is a valid, low-cost software option for simulating clinical scenarios and is widely used in medical education. It is unclear whether VP can be used to assess the quality of PHC.

Objective

This study aimed to examine the agreement between VP and USP assessments of PHC quality and to identify factors influencing the VP-USP agreement.

Methods

Eleven matched VP and USP case designs were developed based on clinical guidelines and were implemented in a convenience sample of urban PHC facilities in the capital cities of the 7 study provinces. A total of 720 USP visits were conducted, during which on-duty PHC providers who met the inclusion criteria were randomly selected by the USPs. The same providers underwent a VP assessment using the same case condition at least a week later. The VP-USP agreement was measured by the concordance correlation coefficient (CCC) for continuity scores and the weighted κ for diagnoses. Multiple linear regression was used to identify factors influencing the VP-USP agreement.

Results

Only 146 VP scores were matched with the corresponding USP scores. The CCC for medical history was 0.37 (95% CI 0.24-0.49); for physical examination, 0.27 (95% CI 0.12-0.42); for laboratory and imaging tests, –0.03 (95% CI –0.20 to 0.14); and for treatment, 0.22 (95% CI 0.07-0.37). The weighted κ for diagnosis was 0.32 (95% CI 0.13-0.52). The multiple linear regression model indicated that the VP tests were significantly influenced by the different case conditions and the city where the test took place.

Conclusions

There was low agreement between VPs and USPs in PHC quality assessment. This may reflect the “know-do” gap. VP test results were also influenced by different case conditions, interactive design, and usability. Modifications to VPs and the reasons for the low VP-USP agreement require further study.

Critical Thinking and Conflict Resolution in a Political Youth Setting
Authors: Dodo Obediah
Published: October 2022

Some circles have wondered if some of the recorded conflicts in Zimbabwe might not have been either averted or stopped had appropriate approaches and attitudes been adopted at various levels. Against this background, the study explores the place, feasibility and role of critical thinking in conflict resolution with particular focus on political youth setting in Zimbabwe. A qualitative online research was conducted with 44 youth drawn from Harare. The survey had questions about the youth’s understanding of critical thinking, respective application and its impact in conflict resolution processes. The study also analysed 10 selected court case verdicts drawn from the Zimbabwe courts between 1988 and 2015. The cases were selected because they relate to cases where the accused could have applied some critical thinking skills. To analyse data, SPSS was complimented with Narrative Content Analysis. The study was guided by the concept of reason and logic as enshrined in critical thinking. The study established that critical thinking is a new phenomenon yet to be appreciated by most youth. However, wherever applied, the phenomenon has helped ease the process and situation and helped analyse surrounding fundamentals.

Authors: Yan Mo
Published: October 2022

Combined with the ubiquitousness of internet, technological gadgets and digital tools, mobile assisted language learning is undergoing rapid development and online reading has become an integrated part of college English education, especially in medical colleges, which requires students to get corresponding reading skills and strategies in their daily study. Metacognitive strategies, as one of language learning strategies, has been a heated topic in students’ English reading, but the awareness and use of them in online English reading haven’t been emphasized. Since metacognitive strategies are of great help to effective online reading and autonomous learning, it is essential to know whether they have been used or to what extent they have been employed and then to explore some suggestions for college English teaching and learning. Based on 296 questionnaires and six students’ think-aloud sessions, this study focused on the use of metacognitive online reading strategies by medical college students, aiming to explore the frequency of metacognitive online reading strategies employed by college students and to know the differences in the use of metacognitive online reading strategies of college students with different English proficiency, then to search for effective ways to help students become autonomous language learners.
Status of a child witness involved in the offence of an adult in criminal procedure
Authors: Głębocka Justyna
Published: October 2022

Giving special importance to the rights of the child, international and European instruments set certain standards aimed at strengthening their guarantees.
The standards improving the juvenile offender’s status intend to ensure procedures that take account of the child’s welfare and strengthen their procedural position which, otherwise, because of their age and psychophysical development may be more vulnerable than in the case of an adult’s one. They refer directly to a juvenile offender in case of whom legal proceedings are conducted. This paper aims to clarify underlying issues of a specific procedural configuration, where separate proceedings are conducted regarding a juvenile offender, and separate criminal proceedings before a criminal court are run against an accused adult whose act is related to the juvenile’s act. It attempts to answer, in the context of European standards, the question on the most important rights of a juvenile whose punishable act is in a close relation to an act of an adult offender, and who, for this reason, appears in a criminal trial as a witness. This paper takes into account the European Union standards which result from international children’s rights instruments binding across the EU, the child-specific case law of ECtHR as well as the psychological aspects related to the psychophysical development of minors.

First We utilized Linear Regression however it didn't give exact results.So we utilized Logistic Regression which at long last aided in foreseeing regardless of whether a specific individual gets a respiratory failure. A heart attack, likewise called a myocardial localized necrosis, happens when a piece of the heart muscle doesn't get sufficient blood. The additional time that elapses without treatment to re-establish blood stream, the more noteworthy the harm to the heart muscle. Coronary vein illness (CAD) is the primary driver of heart attack. We attempted to foresee whether an individual gets respiratory failure via preparing a model with some heart related features
Rapid prototyping enzyme homologs to improve titer of nicotinamide mononucleotide using a strategy combining cell-free protein synthesis with split GFP
Authors: Yuan Qingyan , Wu Minhui , Liao Yibo , Liang Shuli , Lu Yuan , Lin Ying
Published: October 2022

Engineering biological systems to test new pathway variants containing
different enzyme homologs is laborious and time-consuming. To tackle
this challenge, a novel strategy was developed for rapidly prototyping
enzyme homologs by combining cell-free protein synthesis (CFPS) with
split GFP. This strategy featured two main advantages: 1) dozens of
enzyme homologs were parallelly produced by CFPS within hours, and 2)
the expression level and activity of each homolog was determined
[simultaneously](javascript:;) by using the split GFP assay. As a
model, this strategy was applied to optimize a 3-step pathway for
nicotinamide mononucleotide (NMN) synthesis. Ten enzyme homologs from
different organisms were selected for each step. Here, the most
productive homolog of each step was identified within 24 h rather than
weeks or months. Finally, the titer of NMN was increased to 1213 mg/L by
improving physiochemical conditions, tuning enzyme ratios and cofactor
concentrations, and decreasing the feedback inhibition, which was a more
than 12-fold improvement over the initial setup. This strategy would
provide a promising way to accelerate design-build-test cycles for
metabolic engineering to improve the production of desired products.

Haploidentical donor the donor of choice in the treatment of relapse Hodgkin’s lymphoma
Authors: Elez Marija , Todorovic-Balint Milena
Published: October 2022

Introduction. Modern treatment of Hodgkin?s lymphoma has led to a cure in
60-90% of patients. The problem are patients in whom disease relapse occurs,
or the disease is refractory to initial therapy. The standard relapse
treatment is the application of high-dose chemotherapy with autologous stem
cell transplantation. However, about half of patients experience treatment
failure after autologous stem cell transplantation. Despite the application
of new therapeutic modalities, the disease relapses, so allogeneic stem cell
transplantation is the method of choice in further treatment. Haploidentical
transplantation - yes/no. The donor for an allogeneic transplant can be
related or unrelated to human leukocyte associated antigen-matched or
haploidentical related. Allogeneic transplantation is used in Hodgkin?s
lymphoma because of the strong effect of the graft against lymphoma. The
dilemmas of whether a haploidentical donor compared to a related/unrelated
matched donor are better and when treating of Hodgkin?s lymphoma with
allogeneic stem cell transplantation are presented in this paper.
Conclusion. Allogeneic transplantation is still the only potentially
curative therapeutic option to treat Hodgkin?s lymphoma. In order for the
treatment outcome to be as good as possible, it is necessary to precisely
define the pre-transplant conditioning, as well as the selection of the
donor. Randomized multicenter studies provide answers to all doubts.
Primary immune thrombocytopenia in adults - disease considerations
Authors: Suvajdzic-Vukovic Nada , Pantic Nikola , Pravdic Zlatko , Cvetkovic Mirjana , Sabljic Nikica , Mitrovic Mirjana
Published: October 2022

Introduction. Primary immune thrombocytopenia is a chronic acquired
autoimmune disorder that is characterized by isolated thrombocytopenia (<100
x109/L) and the absence of any underlying cause. Treatment of primary immune
thrombocytopenia. While splenectomy has a curable potential, it carries
long-term risk of infection and thromboembolic complications. Therefore, the
use of splenectomy has declined with the advent of rituximab and agonists of
thrombopoietin receptors. The efficacy of rituximab is good for the
short-term outcome, and the majority of patients will relapse. On the other
hand, agonists of thrombopoietin receptors induce remission in only 10-30%
of patients after treatment discontinuation, and long-term treatment is
often required. Health - related quality of life. Immune thrombocytopenia
and its treatments may affect the entire spectrum of patients? lives,
encompassing daily activities, emotional health, energy level, fatigue, and
work productivity. Primary immune thrombocytopenia World Impact Survey was
conducted to discern how immune thrombocytopenia and associated treatments
affect patient lives. Concerns about unstable platelet count, low energy
levels, inability to exercise, and reduced participation in hobbies and work
had the greatest negative impact. While most patients reported ?good
health?, nonetheless half of patients reported a negative impact on their
emotional well-being that worsened with increasing burden of disease and was
often substantial. Conclusion. Although several important improvements have
been made in immune thrombocytopenia treatment algorithms, there is still
room for improvement. One of the possible options could be early, intensive
treatment of immune thrombocytopenia, which might reduce the risk of disease
progression and consequently improve patients? quality of life.
El uso de la tecnología en el proceso creativo del compositor Pablo Rubio: dat.rec y Nosferatu
Authors: Hernández Prado Alonso
Published: October 2022

Este artículo surge a raíz de una entrevista realizada el 3 de marzo de 2022 al compositor Pablo Rubio Vargas (Aguascalientes, 4 de julio de 1984), cuyo objetivo, además de repasar su formación como compositor, fue indagar sobre dos de sus obras musicales que implementan recursos tecnológicos: dat.rec y “apariciones”, la musicalización de un fragmento de la película muda Nosferatu: Una sinfonía del horror dirigida por Friedrich Wilhelm Murnau. La información emanada de la entrevista permite vislumbrar cómo la música, sorprendentemente a la par de ser una herramienta para mitigar desastres ecológicos, es una de tantas facetas del quehacer humano que se ha visto beneficiada o enriquecida con el desarrollo tecnológico. El uso de la tecnología, desde la perspectiva del artista, permite ampliar el umbral del creador artístico y encontrar nuevos caminos para concretar propuestas musicales. Pablo Rubio, consciente de lo anterior, también desarrolla sus dotes en la improvisación musical, para hacer este recurso interpretativo diferente y más rico y así lograr una nueva propuesta, sin dejar de lado un ingrediente primordial, la ejecución musical, que funde, en su caso, al guitarrista con el compositor.

Hacia una gobernanza de los datos de las plataformas. Explorando los desajustes entre los datos y el sentido
Authors: Rodriguez-Amat Joan Ramon
Published: October 2022

Este artículo es una contribución a los debates sobre gobernanza de datos y de las plataformas. La invisibilidad de los procesos de los datos tras principios de automatización (algoritmos, machine learning) dificultan su gobernanza. La primera parte del texto explora el concepto de plataforma y plataformización como cercamientos, y discute algunos de los problemas alrededor de la legitimidad y gobernanza de las plataformas y su falta de encaje con los marcos legales vigentes. La segunda parte se dedica a los recorridos de los datos dentro de las plataformas. El texto aplica un modelo basado en las teorías del sentido de Verón para explorar la (in)visibilidad de los datos. Se señalan momentos y niveles en los que se producen desfases de sentido entre el discurso social y el proceso físico de la producción, gestión, y transmisión de los datos digitales. Aplicando este modelo se pueden des-automatizar procesos de interpretación que parecían ocultos abriendo espacios para las discusiones sobre ética y sobre gobernanza de los datos en las plataformas.

Published: October 2022

Com o auge do êxodo rural, as cidades começaram a crescer desenfreadas, desencadeando a modificação da natureza, causando um grande dano ao ecossistema da região. Com esses problemas o ser humano buscou na arborização publica um meio de amenizar esses estragos. O objetivo principal foi conhecer a diversidade de plantas utilizadas na arborização urbana das vias públicas do município de Picos assim como identificar a ocorrência de espécies tóxicas listadas no SINITOX. Realizando visitas semanais ao bairro centro, constatou-se um total de 250 árvores, as quais são pertencentes a 17 espécies, as quais classificadas em 13 famílias.Três espécies foram as mais abundantes, Azadirachta indica com 76,8%, Ficus benjamina 7,2%, Terminalia catappa 4,8%. Ao criar três classes de altura que vão de 0 a 11 metros, dos 250 espécimes coletados, 150 apresentaram tamanho de 0 a 4 metros sendo inclusos na classe 1. Ao final da pesquisa constatou-se que 98% das espécies são exóticas. Das 17 espécies não foi encontrado nem uma das no SINITOX. Com toda a pesquisa foi notado que a uma tendência regional na arborização, onde acontece a troca de espécies nativas pela Azadirachta indica que é uma espécie exótica e de rápido desenvolvimento.Palavras-Chave: Arborização; Vias Publicas; Crescimento urbano
Comparative analysis of CR of ideological and political education in different regions based on improved fuzzy clustering
Authors: Chen Hongwei
Published: October 2022

Vigorously developing ideological and political education (IPE) is the only way to boost talent training, and scientific and technological progress, and lead to the upgrading of the economic structure. Therefore, by analysing the internal relationship between the current social and economic growth and the development of IPE in colleges, this article introduces the investment of IPE into the social production function model where the gravity search method is used to optimise fuzzy clustering, and the classified data sets of each province in China are determined by genetic algorithm. In addition, the calculation model of contribution rate (CR) of IPE in different regions based on an improved fuzzy clustering algorithm is established, and the influence of IPE on regional economic development in eastern, western and central regions is compared and analysed, which is helpful to realise the optimal allocation of educational resources in China.
Evolutionary Algorithm for Selecting Dynamic Signatures Partitioning Approach
Authors: Zalasiński Marcin , Laskowski Łukasz , Niksa-Rynkiewicz Tacjana , Cpałka Krzysztof , Byrski Aleksander , Przybyszewski Krzysztof , Trippner Paweł , Dong Shi
Published: October 2022

In the verification of identity, the aim is to increase effectiveness and reduce involvement of verified users. A good compromise between these issues is ensured by dynamic signature verification. The dynamic signature is represented by signals describing the position of the stylus in time. They can be used to determine the velocity or acceleration signal. Values of these signals can be analyzed, interpreted, selected, and compared. In this paper, we propose an approach that: (a) uses an evolutionary algorithm to create signature partitions in the time and velocity domains; (b) selects the most characteristic partitions in terms of matching with reference signatures; and (c) works individually for each user, eliminating the need of using skilled forgeries. The proposed approach was tested using Biosecure DS2 database which is a part of the DeepSignDB, a database with genuine dynamic signatures. Our simulations confirmed the correctness of the adopted assumptions.

We propose a method for content-based retrieving solar magnetograms. We use the SDO Helioseismic and Magnetic Imager output collected with SunPy PyTorch libraries. We create a mathematical representation of the magnetic field regions of the Sun in the form of a vector. Thanks to this solution we can compare short vectors instead of comparing full-disk images. In order to decrease the retrieval time, we used a fully-connected autoencoder, which reduced the 256-element descriptor to a 32-element semantic hash. The performed experiments and comparisons proved the efficiency of the proposed approach. Our approach has the highest precision value in comparison with other state-of-the-art methods. The presented method can be used not only for solar image retrieval but also for classification tasks.
The Eurasian security system: a preliminary framework for understanding the emerging Sino–Russian relationship
Authors: Kukkola Juha , Puranen Matti
Published: October 2022

After the Russian invasion of Ukraine, Sino–Russian relations have rapidly become a hotly debated topic within the fields of strategic studies and international relations. In this article, we propose a preliminary theoretical model for analysing the Russian–Chinese relation as a complex security system. By security system, we mean a system consisting of two or more elements (states) with shared and interdependent security concerns and interests. From the shared understandings of security of the elements, the system emerges with its emergent attributes and properties. After providing its theoretical and conceptual framework based on recent ideas in complex system theories, the article narrates how the Eurasian security system began to develop after the restructuring of global and Eurasian security architectures following the collapse of the Soviet Union in 1991. During the following decades, China and Russia developed mutually homogenous sets of perceived security threats and interests, and later in the post 2014-era, these interests converged to establish the Eurasian security system.
Multivariate Nonconformity Analysis for Paving Stone Manufacturing Process Improvement
Authors: Knop Krzysztof
Published: October 2022

The article presents the result of multidimensional analysis of ‘Behaton’ type paving stones’ nonconformities for improving the production process by improving the quality of the final product. Statistical tools, including SPC tools and quality tools, both basic and new, were used to analyse nonconformities in the spatial-temporal system, i.e. according to the type of nonconformity and according to the examined months. The purpose of using the data analysis tools was to thoroughly analyse the cases of nonconformities of the tested product, obtain information on the structure of these nonconformities in the various terms, and information on the stability and predictability of the numerical structure of nonconformity over time. Potential causes influencing a large percentage of paving stone defects were identified, factors and variables influencing the most frequently occurring nonconformities were determined, and improvement actions were proposed. As a result of the multidimensional and multifaceted analyses of paving stone nonconformities, it was shown that in the structure of nonconformity there were cases that were unusual in terms of the number of occurrences, and the lack of stability in the number of nonconformities in terms of the examined months was proven. Three critical nonconformities of the tested product were identified: side surface defects, vertical edge defects, and scratches and cracks. It was determined that the most important factor causing a large percentage of nonconformity was the time of shaking and vibrating the concrete, which was significantly related to the technical condition of the machines, and the most important reason for a large percentage of paving stone nonconformity was the lack of efficient maintenance. Machine, method, and man turned out to be the most important categories of problem factors and specific remedial actions were proposed. A multidimensional look at the structure of paving stone nonconformity as well as the factor and causes causing them has brought a lot of valuable information for the management staff of the analysed company, thanks to which it is possible to improve the production process and improve the quality of the final product.
CFD Optimisation of the Longitudinal Volume Distribution of a Ship’s Hull by Constrained Transformation of the Sectional Area Curve
Authors: Kraskowski Marek
Published: October 2022

The paper presents a proposal for a formalised approach to hull shape optimisation with respect to total resistance, by fine-tuning longitudinal volume distribution. An algorithm for automated modification of the hull is presented, allowing for varying the sectional area distribution with a negligible influence on the resulting displacement. Computational fluid dynamics (CFD) solver STAR-CCM+ and computer computer-aided design (CAD) software NX were used to search the optimal volume distribution of selected parent shapes, with respect to total resistance. The bow part and the aft part were optimised separately. The resulting resistances of the selected optimal shapes were then verified by means of scale model tests, realised in the towing tank at the Maritime Advanced Research Centre (CTO) S.A. A noticeable gain in total resistance was achieved and confirmed by experimental tests. The proposed approach seems to be a promising method for relatively quick parametric optimisation of the designed hull shapes; it is also applicable for generic CFD optimisation studies.

Published: October 2022

In order to study the flow field characteristics of cushion system of partial air cushion support catamaran (PACSCAT) in waves, an analysis was carried out involving flexible treatment on the bow and stern air seals to simulate air seal shape under test conditions by means of computational fluid dynamics method and fluid structure interaction (FSI) method. On this basis, the pressure conditions of the air cushion chamber and the pressurized chamber at different wavelengths and different speeds are studied and compared with experimental results. The experimental results show that: for the air cushion pressure, the nonlinear characteristics of the numerical calculation results are more subtle than the experimental values, after linear transformation, the amplitudes of the experimental values are obviously greater than the calculated values after linear transformation, but the average values are not much different; At low speed of 2.0m/s, the spatial pressure distribution of the pressurized chamber and the air cushion chamber are uniformly distributed, at high speed of 3.6m/s, except for a certain pressure jump occurred in the air cushion chamber near the stern air seal, the pressure in other spaces is also evenly distributed, it proves that the pressurized chamber type of air intake can effectively meet the air cushion pressure balance.

Published: October 2022

Oil and gas projects differ from regular investment projects in that they are frequently large-scale, categorised as vital national projects, highly technological, and associated with significant risks. Drilling rigs are a crucial component of the oil and gas sector and the majority of the systems and equipment aboard drilling rigs are operated automatically. Consequently, it is crucial to address the topic of an advanced control theory for off-shore systems. Network technology connected to control is progressively being used to replace outdated technologies, together with other contemporary technologies. In this study, we examine how to adapt a networked control jacking system to the effects of internal and external disturbances with a time delay, using a Fuzzy controller (FC)-based particle swarm optimisation. To demonstrate the benefit of the proposed approach, the developed Fuzzy Particle Swarm Optimisation (FPSO) controller is compared with the fuzzy controller. Finally, the results from simulations and experiments utilising Matlab software and embedded systems demonstrate the suitability of the proposed approach.
Monitoring the Performance of a Ship’s Main Engine Based on Big Data Technology
Authors: Liang Meng , Chen Mingzhi
Published: October 2022

Under the recent background of ‘Green Shipping’ and rising fuel prices, it is very important to reduce the fuel consumption rate of ships, which is directly affected by the performance of the main engine. A reasonable maintenance schedule can optimise the performance of the main engine. However, a traditional maintenance schedule is based on the navigation distance and time, ignoring many other factors, such as a harsh working environments and frequently changing operating conditions, which will lead to faster performance degradation. In this study, a real-time evaluation method combing big data of ship energy efficiency with physics-based analysis is proposed to judge the degradation of main engine performance and assist in determining the maintenance schedule. Firstly, based on the developed ship energy efficiency big data platform, the distribution statistics and comparison of different operating states are carried out. Gaussian mixture model (GMM) and Density-Based Spatial Clustering of Applications with Noise (DBSCAN) are used to cluster the data and the high-density data areas are obtained as the analysis points. Then, the data of the analysis points are polynomial fitted, by the least square method, to obtain the propulsion characteristics curves, load characteristic curves, and speed characteristic curves, which can be used to observe the performance degradation of the main engine. The results show that this method can effectively monitor the degradation degree of the main engine performance, and is of great significance to fuel efficiency improvements and greenhouse gas (GHG) emissions reduction.
Influence of Material Thickness on the Ductile Fracture of Steel Plates for Shipbuilding
Authors: Kowalski Jakub , Kozak Janusz
Published: October 2022

In the shipbuilding industry, the risk of brittle fractures is relatively high because some units operate in arctic or subarctic zones and use high thickness (up to 100 mm) steel plates in their structures. This risk is limited by employing certified materials with a specific impact strength, determined using the Charpy method (for a given design temperature) and by exercising control over the welding processes (technology qualification, production supervision, and non-destructive tests). However, for offshore constructions, such requirements may prove insufficient. For this reason, regulations employed in constructing offshore structures require conducting crack tip opening displacement (CTOD) tests for steel and welded joints with thicknesses exceeding 40 mm for high tensile strength steel and 50 mm for other steel types. Since classification codes do not accept the results of CTOD tests conducted on specimens of sub-sized dimensions, the problem of theoretically modelling the steel construction destruction process is of key importance, as laboratory tests for notched elements of considerable thickness (100 mm and higher) are costly and problems stemming from high loads and a wide range of recorded parameters are not uncommon. The aim of this research is to find a relationship between material thickness and CTOD value, by establishing and verifying a numerical model that allows recalculating a result obtained on a sub-size specimen to a full- size specimen for a ductile fracture mode. This work presents results and conclusions from numerical modelling and compares them with laboratory test results of the elastic-plastic properties of high thickness steel, typically used in offshore applications.

Published: October 2022

The article presents an innovative method of corrosion tests using the acoustic emission method and the corrosion tester. The problem of corrosion occurring in ballast tanks and tanks carrying petroleum products is discussed. The acoustic method is presented which, due to the use of a unique corrosion tester, is used to monitor the course of corrosion processes in steel. The principle of operation of the corrosion tester, its construction and its use in Non Destructive Testing (NDT) are described in detail. Corrosion test results, obtained with the use of a corrosion tester, are presented. An analysis and a short discussion of the obtained results are given. The results of both the acoustic and metallographic tests prove the possibility of detecting material damage occurring during the operation of the corrosion tester, allowing determination of the course and type of corrosion damage.
