Authors: Tian Xiange , Becerra Victor , Bausch Nils , Vinod Gopika , Santhosh T.V.
Published: March 2024

The diagnosis of loss of coolant accidents (LOCA) in nuclear reactors has attracted a great deal of attention in condition monitoring of nuclear power plants (NPPs) because the health of cooling system is crucial to the stability of the nuclear reactor. Multi-layer perceptron (MLP) neural networks have commonly been applied to LOCA diagnosis. The data used for training these models consists of a number of time-series data sets, each for a different break size, with the transient behavior of different measurable variables in the coolant system of the reactor following a LOCA. It is important to select a suitable architecture for the neural network that delivers robust results, in that the predicted break size is deemed to be accurate even for a break size that is not included in the training data sets. The objective of this paper is to present a simple method for measuring the robustness of diagnostic models for predicting the break size during the loss of coolant accidents. A robustness metric is proposed based on the leave-one-out approach and the mean squared error resulting from a diagnostics model. Using this metric it becomes possible to compare the robustness of different diagnostic models. Given data obtained from a high fidelity simulation of the coolant system of a nuclear reactor, four different diagnostic models are obtained and their properties compared and discussed. These models include a fully connected multi-layer perceptron with one hidden layer, a fully connected multi-layer perceptron with two hidden layers, a multi-layer perceptron with one hidden layer that is pruned using the optimal brain surgeon algorithm, a group method of data handling (GMDH) neural network, and an adaptive network based fuzzy inference system (ANFIS).
Leak detection in compressed air systems using unsupervised anomaly detection techniques
Authors: Desmet Antoine , Delore Matthew
Published: March 2024

Critical components of mobile mining machinery, such as brake and lubrication, are typically powered by compressed air. The compressed air system is subject to leaks in either pipelines or the air-actuated components; and these leaks can cause accelerated wear or unexpected machine shutdowns. Given the size of these machines, fault-finding can be timeconsuming. Remote diagnostics is possible by analysing the machine’s air accumulator pressure with respect to component activation times. However, since every component draws air directly from the accumulator, the resulting drops in pressure all superimpose over the accumulator’s charge and discharge cycles. The result is a highly dynamic trend, making visual diagnostic difficult for anything but major leaks. In this paper, we apply unsupervised anomaly detection techniques to detect developing air leaks. Our method uses machine learning to associate patterns in pressure drop from the accumulator with the activation of each air-powered component. We first apply a wavelet transform to the accumulator pressure trend to make patterns apparent in the time-frequency domain. We then use the Random Forest algorithm’s feature importance to select the most informative wavelet scales. Finally, we trial two anomaly detection methods over the selected inputs: the first uses a clustering approach (LOF), while the second uses a neural-network approach (autoencoder).Once the learning phase (using historical data) is complete, we test the system on an intermittent leak which occurs only when a particular component is activated. We find that both systems perform well, and the LOF trades accuracy for speed with respect to the autoencoder.
Why autonomous assets are good for reliability – the impact of ‘operator-related component’ failures on heavy mobile equipment reliability

Published: March 2024

This study examines the maintenance records for components necessary for the comfort and safety of the operators of heavy mobile equipment. The results show that air conditioners, ladders, driver’s seats and mirrors and other required operator-related components can have a significant impact on an asset’s reliability. Analysis was conducted on 10 years of work orders for five identical 1400HP shovels and three identical 1470HP shovels. The results suggest that removing operator-related components contribute to a 15% decrease in the number of work orders and an 8% increase in reliability. In an autonomous asset these components would not be required. The key to this analysis is a rule-based expert system used to clean more than ten thousand work orders and allocate events to specific sub-systems with associated failure modes. While the mining industry has moved to autonomous haul trucks and drills, there are as yet no autonomous shovels. For manufacturers looking at the business case for these units, the availability of data on the reliability increase from removing the operator-related components will be valuable information.

Authors: Chhokra Ajay , Mahadevan Nagabhushan , Dubey Abhishek , Balasubramanian Daniel , Karsai Gabor
Published: March 2024

Cascading failures in critical cyber physical systems such as power systems are rare but lead to huge social and economic implications. Timely diagnosis of faults in these systems is a challenging task due to inherent heterogeneity and scale of the system. In the past, we have successfully demonstrated a robust technique for diagnosing independent component faults using Temporal Causal Diagrams (TCD) at sub-system level. In this paper, we present a systematic approach of using the sub-system level fault models to auto-generate a systemlevel fault model that helps in diagnosing cascading failures. We show the time complexity of our model generation algorithm using industry standard Power Transmission networks. Further, we describe the updates to the existing TCD reasoner algorithms and report the TCD diagnosis results for simulated multi fault scenario on a standard power system.
Diagnosis and Prognosis of Fuel Injectors based on Control Adaptation
Authors: Sarwar Azeem , Sankavaram Chaitanya , Lu Xiangxing
Published: March 2024

Spark Ignition Direct Injection (SIDI) technology enables better fuel economy and tail pipe emissions in vehicles equipped with gasoline engines. The SIDI technology depends on the ability of the system to deliver fuel at high pressure directly into the combustion chamber, hence making thefuel injectors key subcomponents. Reliable performance of fuel injectors is vital as it directly relates to the operability of the vehicle, and hence customer satisfaction in case of failure. It, therefore, becomes very important to devise a scheme that can effectively diagnose and prognose such a component. In this article, algorithm development for diagnosis and a pathway to prognosis of fuel injectors is presented. We do not propose any additional sensing capability, and make use of what is available in most of the production vehicles today across the industry. In particular, the control adaptation of fuel control and the associated diagnostics that are mandated by regulators are employed to generate schemes for fault detection, fault isolation, and fault prediction. Results are presented from vehicle test data that allow development of such a scheme for fuel injectors.
Identifying the Gaps in the Management of Work Integrated Learning Among TVET College National Certificate (Vocational) Students
Authors: Molele Masilu Bunny , Khoza Samuel Dumazi , Skosana Ndlelehle Miskien
Published: March 2024

Work Integrated Learning (WIL) is a crucial activity for students enrolled in Technical and Vocational Education and Training (TVET) programs in South Africa and globally. Effective management of this activity is essential to ensure that students are well-prepared for their placement in the workplace. Unfortunately, the current situation in South African TVET colleges often falls short, with students frequently finding themselves in workplaces where they lack the necessary readiness. To address this issue, a mixed-method approach was employed to select 50 Level 4 students from the National Certificate Vocational program and four Work Integrated Learning (WIL) coordinators. The objective was to identify the challenges faced by students during their WIL experience. Data was collected through questionnaires administered to the students and face-to-face interviews conducted with the WIL coordinators. The findings of the study revealed that 68% of the students were not adequately informed about workplace dynamics, which posed a significant challenge. Additionally, 82% of the respondents stated that they were never briefed on the employer's expectations upon their arrival at the workplace. While students found the activities in the workplace interesting, they observed a noticeable gap between what they learned in college and the realities of the industry. These challenges clearly indicate a lack of proper WIL management in the TVET colleges. To address these issues, it is recommended that the college curriculum planner collaborates closely with industries to align the curriculum with industry expectations and requirements. This synergy will enhance students' WIL experience and better prepare them for the workplace.
„Tańcz, opowiedz im wszystko…”: Losy tancerek żydowskich w czasach Holokaustu
Authors: Leyko Małgorzata
Published: March 2024

W artykule po raz pierwszy podjęto badania nad losami tancerek żydowskich w czasach Holokaustu. Nowoczesny taniec artystyczny stanowił próbę zdefiniowania własnej tożsamości przez młode kobiety żydowskie, które kwestionowały dotychczasowy model wychowania w tradycji patriarchalnej. Z tego powodu kształcenie w szkołach tańca było bardzo popularne wśród dziewcząt i kobiet żydowskich, a ich absolwentkami mogło być w okresie przedwojennym nawet kilkaset osób. W pracy przyjęto metodę skoncentrowaną na prezentacji losów jednostkowych, które mogą ilustrować skalę opresji, jakiej doświadczały tancerki żydowskie. Ich losy przedstawiono jako realizację trzech matryc biograficznych: emigracja/ucieczka/wygnanie, życie w gettach i próba przetrwania po aryjskiej stronie. Artykuł jest jednocześnie postulatem w sprawie podjęcia systematycznych badań nad tym zagadnieniem.

Published: March 2024

Objective: The aim of this research is to determine empirically the impact of geopolitical risk originating from countries with high geopolitical risk and domestic ones on the Composite Stock Price Index in Indonesia. In addition, this research aims to determine the role of geopolitical actions in strengthening or weakening the relationship between geopolitical risk and the Composite Stock Price Index in Indonesia.
Design/Methods/Approach: This research uses geopolitical risk index (GPRH) data from countries with the highest geopolitical risk index in the last 3 years and domestic ones consisting of Ukraine, Russia, America, China and Indonesia. Meanwhile, geopolitical action risk (GPRA) is a risk index measured in aggregate from January 2004-October 2023, so the number of observations in this study reached 238.
Findings: The findings in the research show that Ukraine and America have a negative and significant influence, while China and Russia have a positive and significant impact on the composite stock price index in Indonesia. Apart from that, this research also found that the influence of geopolitical risk on the composite stock price index in Indonesia is greater when geopolitical actions such as escalation of war and acts of terror occur.
 
Originality/Value: This research complements several previous studies regarding the impact of geopolitical risk on the Indonesian composite stock price index. Several previous studies have not examined the impact of each country's geopolitical risk on the composite stock price index and how it is moderated by geopolitical action.
Practical/Policy implication:
The findings in this research prove that countries that have high geopolitical risk have a significant influence on the Composite Stock Price Index in Indonesia.

Les pièces de théâtre de Matéi Visniec – Source d’inspiration pour des créations non conventionnelles
Authors: Ștefan Ruxandra Vera
Published: March 2024

The type of theatre proposed by the playwright Matei Vișniec offers great freedom to theatre creators and more. His plays can also be a starting point for light, sound, image installations. By its very nature, interdisciplinarity is born from the union of fragments from different fields, and Matei Vișniec’s dramaturgy is one that works as well in its entirety as it does fragmentally. Refusing structural constraints, as if, with each new play, he were intending to liberate it from the rules of writing, transgressing the usual boundaries of time and space and, of course, those of the psychology of the characters, Matei Vișniec’s theatre can be the seed for various types of artistic expression. They can just as well be the basis for psychological research since they are paradoxical snippets of life, so unusual and, at the same time, so repeatable. In the article, using some existing visual landmarks, we will trace and create in the imagination spaces proposed by the playwright in some of his plays, at the same time watching if and how the message of the text is reshaped.
Análisis tafonómico y zooarqueológico de los huesos de aves de Parador QB, (Parque Nacional Islote Lobos, provincia de Río Negro, Argentina)
Authors: Borella Florencia , Cruz Isabel
Published: March 2024

Durante las primeras excavaciones realizadas en el Parador QB (Parque Nacional Islote Lobos, costa Rionegrina) se recuperaron huesos de aves en los conjuntos zooarqueológicos. Al igual que en otras localidades arqueológicas del litoral Nordpatagónico, la representación de este taxón es escasa, aunque los huesos presentan buen estado de preservación. Con el objetivo de explorar el papel de las aves en la subsistencia de las sociedades cazadoras-recolectoras que ocuparon este litoral durante el Holoceno tardío, desarrollamos un estudio tafonómico para establecer si la depositación de sus huesos se debe a la acción antrópica o a causas naturales. La evaluación tafonómica de los restos avifaunísticos es fundamental dado que actualmente existen áreas de nidificación de diversas aves marino-costeras próximas a los sitios arqueológicos, por lo que sería factible la “contaminación ósea” -o mezcla de huesos naturales y materiales arqueológicos. Se concluye que los huesos de aves de los tres loci tienen trayectorias tafonómicas similares, mientras que la mezcla de restos óseos de diferente origen se registró principalmente en el caso de los pingüinos de Magallanes. Por último, señalar que, aunque las aves no son tan abundantes, tuvieron un lugar importante en el repertorio de presas de los cazadores-recolectores de la región.

This study aims to evaluate the relationship between the level of self-management of medication and blood glucose levels in outpatient type 2 diabetes mellitus patients at the Kediri City Health Center. The research falls under the category of quantitative research with an observational study approach, using a cross-sectional design. Diabetes mellitus (DM) is a chronic condition characterized by hyperglycemia and various metabolic abnormalities due to hormonal disorders, which can lead to long-term complications in the eyes, kidneys, nerves, and blood vessels. Data were collected using the DSME Questionnaire (Diabetes Self Management Education) to assess the level of self-management of medication.The results showed that 12 respondents (13.8%) had poor self-management of medication and poor blood glucose control. There were 14 respondents (22.2%) with moderate self-management of medication and uncontrolled blood glucose. Meanwhile, 18 respondents (28.6%) had moderate self-management and blood glucose within the normal range. A total of 31 respondents (49.2%) had moderate self-management and normal blood glucose levels. Only 12 respondents (13.8%) had good self-management and blood glucose within the normal range.The Spearman rank test results indicated a significant relationship between self-management of medication and blood glucose levels in type 2 diabetes mellitus patients. With α = 0.05, the obtained P-value was 0.000, which is smaller than 0.05. Therefore, the alternative hypothesis (H1) is accepted, while the null hypothesis (H0) is rejected. This suggests the presence of a relationship between self-management of medication and blood glucose levels, with a Spearman rank correlation coefficient of 0.598.

Diabetes mellitus is a disorder of blood sugar metabolism chronically characterized by high blood sugar levels resulting from impaired insulin secretion, insulin resistance, or both. Treatment of diabetes mellitus consists of four pillars: education, medical nutrition therapy (MNT), and physical and pharmacological therapies. One of the plants that can be used as a medicinal ingredient is guava leaves. Guava (Psidium guajava L.) leaves are a group of herbal plants with a chemical content that is good for health. Therefore, guava (Psidium guajava L.) leaves are plants that are efficacious as medicine. This plant contains secondary metabolites that act as antidiabetics. Thus, the research aimed to determine the effectiveness of ethanol extract of guava (Psidium guajava L.) leaves on the decrease in blood sugar levels in male mice. The research method employed was maceration, phytochemical screening, and antidiabetic testing with the pre-test and post-test control group design methods to determine if there was a decrease after administration of the extract. The findings indicated that the phytochemical screening test found that guava (Psidium guajava L.) contained secondary metabolites, including alkaloids, flavonoids, and tannins. In contrast, the antidiabetic test revealed that three extracts with concentrations of 50 mg, 100 mg. and 200 mg could decrease blood sugar levels by 15%, 21%, and 47%, respectively. From these findings, it can be concluded that antidiabetic compounds which play a role in the ellanol extrict of guava (Psidium guajava L.) leaves are alkaloids, flavonoids, and tannins.

Autophagy is a cellular catabolic process characterized by the formation of double-membrane autophagosomes. Transmission electron microscopy is the most rigorous method to clearly visualize autophagic engulfment and degradation. A large number of studies have shown that autophagy is closely related to the digestion, secretion, and regeneration of gastrointestinal (GI) cells. However, the role of autophagy in GI diseases remains controversial. This article focuses on the morphological and biochemical characteristics of autophagy in GI diseases, in order to provide new ideas for their diagnosis and treatment.

Published: March 2024

BACKGROUND

Fecal microbiota transplantation (FMT) is a promising therapeutic approach for treating Crohn’s disease (CD). The new method of FMT, based on the automatic washing process, was named as washed microbiota transplantation (WMT). Most existing studies have focused on observing the clinical phenomena. However, the mechanism of action of FMT for the effective management of CD-particularly in-depth multi-omics analysis involving the metagenome, metatranscriptome, and metabolome-has not yet been reported.

AIM

To assess the efficacy of WMT for CD and explore alterations in the microbiome and metabolome in response to WMT.

METHODS

We conducted a prospective, open-label, single-center clinical study. Eleven CD patients underwent WMT. Their clinical responses (defined as a decrease in their CD Activity Index score of > 100 points) and their microbiome (metagenome, metatranscriptome) and metabolome profiles were evaluated three months after the procedure.

RESULTS

Seven of the 11 patients (63.6%) showed an optimal clinical response three months post-WMT. Gut microbiome diversity significantly increased after WMT, consistent with improved clinical symptoms. Comparison of the metagenome and metatranscriptome analyses revealed consistent alterations in certain strains, such as Faecalibacterium prausnitzii , Roseburia intestinalis , and Escherichia coli . In addition, metabolomics analyses demonstrated that CD patients had elevated levels of various amino acids before treatment compared to the donors. However, levels of vital amino acids that may be associated with disease progression (e.g. , L-glutamic acid, gamma-glutamyl-leucine, and prolyl-glutamine) were reduced after WMT.

CONCLUSION

WMT demonstrated therapeutic efficacy in CD treatment, likely due to the effective reconstruction of the patient’s microbiome. Multi-omics techniques can effectively help decipher the potential mechanisms of WMT in treating CD.

Can educational programs have an effect on pupils’ attitudes towards the given topic? An experiment on this topic was conducted among elementary school pupils. This experiment had two phases, in June 2022 students were approached with filling out a questionnaire, the research group first attended an educational program on daily life in ancient Rome. The other half, who did not attend the programme, served as a control group. The questionnaire explored pupils’ attitudes towards antiquity, the perceived meaning of archaeology and its connection to modern history, the representation of antiquity in popular culture and stereotypical ideas about it. The research group also evaluated the educational programme and the benefits of excursions in general. In the second phase (November 2022), pupils in both groups completed a questionnaire aimed solely on pupils’ attitudes towards antiquity. The results of the two groups were then analyzed and compared. A surprising finding for the researchers was that the control group showed a slightly more positive attitude towards antiquity and its importance during both June and November measurements, which may be due to several factors such as the topics discussed in class at that time, the teachers’ teaching methods, and other activities in which the pupils participated that were not controlled during the experiment. There was no positive effect of the educational programme on the consumption of media with the theme of the ancient world (books, films, games, etc.). A slight difference can be seen in the perception of the meaning of archaeology, where the research group is more likely to be inclined towards understanding technology and inventions. One can speculate whether direct contact with replicas of archaeological objects is reflected here. A more significant difference between the control and research groups lies, for example, in the knowledge test.
