Este trabalho apresenta um estudo sobre a modelagem de um motor de indução trifásico (MIT) e os procedimentos necessários para a implementação de um algoritmo para o estimador Filtro de Kalman Estendido (FKE) utilizando dados reais. A aquisição de dados foi realizada utilizando transdutores para a medição de valores instantâneos de sinais em corrente contínua, alternada e pulsada, entre outras formas de onda. Foi utilizado um MIT de 1/3 CV e um inversor de frequência trifásico de uso industrial. Com uma frequência de amostragem de 10 kHz, as medições foram realizadas no circuito elétrico entre o MIT e o inversor. O tempo de partida do motor foi alterado entre um ensaio e outro, assim como a frequência de chaveamento empregada no circuito de potência do inversor. Os dois modos de controle de velocidade disponibilizados pelo fabricante do inversor foram testados. Foram realizados, também, ensaios com o motor de quatro polos energizado sem carga no eixo e a plena carga com o uso de um freio eletromagnético. Por meio do ajuste das matrizes de covariância, foi possível obter um conjunto de valores que satisfizesse com boa concordância a estimativa de velocidade do motor e para todos os ensaios realizados.

Authors: Silva Dominnic , Garcia Enoque
Published: June 2024

A evolução tecnológica observada ao redor do mundo proporciona ao sistema elétrico diversas vantagens englobando conceitos de democratização do uso eficiente da energia elétrica, proporcionando confiabilidade e qualidade no fornecimento do produto. Nesse sentido, influenciado pela significativa adoção de geradores distribuídos, principalmente de características intermitentes e renováveis, impulsionou-se a diversificação de sistemas conhecidos como Microrredes. Esses sistemas, ao contrário de sistemas de distribuição com GD, são circuitos que operam em diferentes topologias, podendo ser on grid ou off grid. Nesse contexto, os sistemas de proteção tradicionais tendem a não operar corretamente devido a alteração nos níveis de falta, afetando a coordenação e seletividade dos dispositivos de proteção. Diante desse cenário, este artigo investiga os impactos causados à operabilidade das proteções através de uma metodologia de pesquisa e uma análise bibliométrica promovendo uma visão abrangente e atualizada do estado da arte em sistemas de proteção para microrredes. Ao final, são discutidas as propostas e contribuições relevantes ao tema, destacando as futuras tendências para mitigar os desafios impostos.

Different techniques are employed to contain the carious process: non-invasive, microinvasive, and invasive, and with restorative needs. Thus, it is essential that dentists are duly updated regarding scientific evidence and perform with skill and precision the techniques proposed as treatment, being aware of the consequences and risks, and aiming at the most conservative therapy. Objective: To identify the clinical practices for the treatment of deep carious lesions used by dental surgeons of the Family Health Strategy (FHS) program of a Brazilian city. Material and methods: This was a quantitative and cross-sectional study carried out with 43 dental surgeons from the FHS program in the city of Sobral, State of Ceará, Brazil, using a Google Forms online questionnaire, containing questions related to the clinical criteria used during caries removal, deep dentin caries removal techniques, lining materials, survival rate of some treatments, in addition to sociodemographic data and questions regarding professional qualification. Results: Among those interviewed, 62.8% were aged between 25 and 30 years. Most dentists (58.7%) considered that the cavity floor should be hard at the end of the carious dentin removal, which demonstrates the non[1]adherence to Selective Carious Tissue Removal (SCTR) protocols. Only 25.6% considered SCTR a treatment with a chance of success and a 2-year survival rate greater than 80%. More than half of the interviewees (51.2%) disagreed with the maintenance of carious tissue in the axial/pulp walls of deep cavities to preserve pulp vitality. More invasive treatments were preferred in a greater proportion by dentists who work exclusively in the public sector (66.7%) compared to those who also work in the private sector (17.6%) [p=0.002], with an evident need for cariology education workshops and more studies on the topic. Conclusion: The dentists who participated in the study showed little adherence to less invasive techniques in the treatment of deep carious lesions.

Unveiling Novel HIV-1 Protease Inhibitors through an Integrated Analysis of 3D-QSAR, Molecular Docking, and Binding Free Energy
Authors: Zhou Guozheng , Shi Yujie , Li Yan
Published: June 2024

Introduction:

HIV-1, the primary causative agent of AIDS, remains a formidable and
lethal virus globally, claiming the lives of millions over the past four decades since its discovery.
Recent research has underscored the potential of HIV-1 protease as a therapeutic target, offering a
promising strategy for inhibiting viral replication within the body.

Methods:

In light of this, we have curated an extensive database comprising 193 derivatives of Darunavir
(DRV), an HIV-1 protease inhibitor. Simultaneously, we have developed a comprehensive
set of 3D-QSAR models to elucidate the structure-activity relationships of these 193 derivative inhibitors.
Employing various computational simulation techniques, including Comparative Molecular
Field Analysis (CoMFA), Comparative Similarity Indices Analysis (CoMSIA), and molecular docking,
we have unveiled the fundamental three-dimensional structural features influencing their biological
activity.

Results:

Results indicate that the optimal CoMSIA model (Q2 = 0.500, R2
ncv = 0.882, R2
pred = 0.797)
surpasses other models, demonstrating superior predictive capability. Furthermore, docking results
suggest that DRV derivatives maintain stable conformations within the binding cavity due to synergistic
interactions, such as hydrogen bonding and non-bonded interactions. Drawing insights from
the best computational models, we have designed five DRV derivatives with significant HIV-1 protease
inhibitory activity through local modification, with theoretical calculations indicating favorable
pharmacokinetic properties and synthetic feasibility for the newly proposed molecules.

Conclusion:

It is hoped that the findings and conclusions obtained herein may furnish theoretical
underpinning and directional guidance for the design, optimization, and experimental synthesis of
DRV derivative compounds for pharmaceutical purposes.

Prevalence Estimate for Adjustment Disorders in the South African Navy
Authors: Van Wijk Charles H.
Published: June 2024

Introduction and Aim

Adjustment Disorder is among the most commonly diagnosed mental disorders in the armed forces, with a mean prevalence estimated at 7.4% across military populations. The prevalence in South African military populations is not known. This study aimed to estimate the prevalence of Adjustment Disorders in the South African Navy and to explore potential risk factors.

Methods

In this cross-sectional study, a representative sample of 714 sailors completed the International Adjustment Disorder Questionnaire, and also provided information from their biennial occupational health assessment mental health screening, which included other clinical screeners of mental health and adjustment history.

Results

The estimated prevalence of Adjustment Disorders in the South African Navy was 6.9%, and was proportionally distributed across gender and age categories. Depression and PTSD were the main comorbid conditions. Risk factors included a) history of adjustment difficulties during military deployment or family adjustment difficulties, b) domestic discord (difficulties in relationship with spouse/partner or immediate family), and c) the experience of stress overload (i.e., that the demands of life are overwhelming available resources).

Conclusion

The estimated prevalence was similar to the expectation of military personnel generally, although the self-report data needs to be interpreted cautiously. The contributing risk factors offer possible direction for targeted intervention, e.g., skills training and relationship counselling to enhance coping with military service and family challenges, and cognitive behaviour therapy generally to address sailors’ experience of stress overload.

ZnO Nanoparticles
Authors: Bhirud Sangita R. , Sarode Chandrakant H. , Gupta Gaurav R. , Chaudhari Ganesh R.
Published: June 2024

Aim::

Ionic liquids belong to the class of green solvents and are distinguished by their
simple yet distinctive physical properties that are related to their structure. These properties include
their remarkable thermal stability, exceptional thermal conductivity, and negligible vapor pressure.
Additionally, they are suitable and inert for a wide range of catalytic applications. Zinc Oxide Nanoparticles
(ZnO-NPs) have been considered a cost-effective choice that requires modest reaction
conditions to provide a high yield of the required products with remarkable selectivity in a short
amount of time. Consequently, an investigation into the synthesis of ZnO-NPs in an ionic liquid
medium has been attempted in the current work.

Background::

The synthesis of metal nanoparticles using highly tunable ionic liquids is being investigated
for many pharmacological applications and their usage in catalysis.

Objectives::

In this context, the current work has used the co-precipitation approach to synthesize
ZnO-NPs. The production of ZnO nanoparticles with a range of morphologies utilizing an imidazolium
ionic liquid system has been the main topic of discussion.

Methods::

The co-precipitation method has successfully been administered for the synthesis of morphologically
diverse nano-crystalline ZnO particles using different ionic liquids, such as 1-propyl-
3-methylimidazolium bromide (pmim)(Br), 1-butyl-3-methylimidazolium bromide ([bmim][Br]),
and 1-hexyl-3-methylimidazolium bromide (hmim)(Br) as an additive

Results::

Modern analytical tools, including X-ray Diffraction (XRD), Scanning Electron Microscopy
(SEM), and FT-IR absorption spectroscopy have been employed to confirm the structure of
these ZnO nanoparticles. The IR absorption peak below 480 cm-1 and the XRD pattern showed all
the peaks in the diffraction diagram, revealing the formation of ZnO-NPs. FE-SEM images showed
various morphologies of ZnO-NPs and they have been found to be separated from the agglomerated
clusters.

Conclusion::

The characteristic results have revealed ionic liquids to have substantial effects on the
size of the zinc nano-species as well as provide the appropriate environment for the growth of the
nanoparticles.

Use of Machine Learning in Credit Card Fraud Detection
Authors: Jayabalan Manoj , Shiksha
Published: June 2024

Credit card fraud is a growing concern, and it poses a significant threat as
individual information is being misused and causing a substantial monetary loss.
Hence, the prevention of credit card fraud is crucial. Credit card fraud detection is used
to differentiate the transactions, either as legitimate or fraudulent. Recently, different
machine learning techniques have been implemented to detect credit card fraud.
However, the main challenge with fraud detection is that the credit card data is highly
skewed, with the fraudulent transactions as less as 1% of the total data. This study
investigates the performance of the four supervised machine learning algorithms:
logistic regression, support vector machine, decision tree, and random forest, along
with different sampling techniques to better understand the fraud detection attributes
and performance measures associated with it. This review is also concentrated on
exploring different works where the model has a better value for all of the performance
evaluation metrics: Recall, precision, F1-score, accuracy, MCC, AUC, and area under
the precision-recall curve. This will detect credit card fraudulent transactions better and
control credit card fraud.
Decentralization and its impact on improving public services
Authors: Ibrahim Abdul Halil Hi
Published: June 2024

Decentralization is the process of transferring decision-making power, authority and responsibility from the central government to regional governments or local entities. The process aims to bring government closer to the people, with the hope of improving the efficiency, accountability and responsiveness of public services to the specific needs of local communities. Decentralization is often regarded as a strategy to optimize resources, strengthen local democracy, and encourage active community participation in the policy-making process and its implementation. This study uses the literature research method. The results show that decentralization tends to improve the effectiveness and relevance of public services by empowering local governments to manage the specific needs of local communities. It creates a platform for wider public participation and increased government accountability and transparency. However, the findings also confirm that the negative elements of decentralization cannot be ignored. In particular, decentralization can result in inequalities in services between regions due to differences in resources, as well as pose policy coordination challenges. Lack of local capacity and the potential for increased corruption are significant obstacles to optimizing the benefits of decentralization.

We hypothesized that the app-based measurement may provide more comprehensive information, including light-sensitive melatonin secretion and social rhythm, and have stronger correlations with adiposity indicators.

Methods

We enrolled a total of 78 participants (mean age 41.5, SD 9.9 years; 46/78, 59% women) from both an obesity outpatient clinic and a workplace health promotion program. All participants (n=29 with obesity, n=16 overweight, and n=33 controls) were required to wear a wrist actigraphy device and install the Rhythm app for a minimum of 4 weeks, contributing to a total of 2182 person-days of data collection. The Rhythm app estimates sleep and circadian rhythm indicators by tracking human-smartphone interactions, which correspond to actigraphy. We examined the correlations between adiposity indices and sleep and circadian rhythm indicators, including sleep time, chronotype, and regularity of circadian rhythm, while controlling for physical activity level, age, and gender.

Results

Sleep onset and wake time measurements did not differ significantly between the app and actigraphy; however, wake after sleep onset was longer (13.5, SD 19.5 minutes) with the app, resulting in a longer actigraphy-measured total sleep time (TST) of 20.2 (SD 66.7) minutes. The obesity group had a significantly longer TST with both methods. App-measured circadian rhythm indicators were significantly lower than their actigraphy-measured counterparts. The obesity group had significantly lower interdaily stability (IS) than the control group with both methods. The multivariable-adjusted model revealed a negative correlation between BMI and app-measured IS (P=.007). Body fat percentage (BF%) and visceral adipose tissue area (VAT) showed significant correlations with both app-measured IS and actigraphy-measured IS. The app-measured midpoint of sleep showed a positive correlation with both BF% and VAT. Actigraphy-measured TST exhibited a positive correlation with BMI, VAT, and BF%, while no significant correlation was found between app-measured TST and either BMI, VAT, or BF%.

Conclusions

Our findings suggest that IS is strongly correlated with various adiposity indicators. Further exploration of the role of circadian rhythm, particularly measured through human-smartphone interactions, in obesity prevention could be warranted.

Authors: Boege Selina , Milne-Ives Madison , Meinert Edward
Published: June 2024

Background

Responsible artificial intelligence (RAI) emphasizes the use of ethical frameworks implementing accountability, responsibility, and transparency to address concerns in the deployment and use of artificial intelligence (AI) technologies, including privacy, autonomy, self-determination, bias, and transparency. Standards are under development to guide the support and implementation of AI given these considerations.

Objective

The purpose of this review is to provide an overview of current research evidence and knowledge gaps regarding the implementation of RAI principles and the occurrence and resolution of ethical issues within AI systems.

Methods

A scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines was proposed. PubMed, ERIC, Scopus, IEEE Xplore, EBSCO, Web of Science, ACM Digital Library, and ProQuest (Arts and Humanities) will be systematically searched for articles published since 2013 that examine RAI principles and ethical concerns within AI. Eligibility assessment will be conducted independently and coded data will be analyzed along themes and stratified across discipline-specific literature.

Results

The results will be included in the full scoping review, which is expected to start in June 2024 and completed for the submission of publication by the end of 2024.

Conclusions

This scoping review will summarize the state of evidence and provide an overview of its impact, as well as strengths, weaknesses, and gaps in research implementing RAI principles. The review may also reveal discipline-specific concerns, priorities, and proposed solutions to the concerns. It will thereby identify priority areas that should be the focus of future regulatory options available, connecting theoretical aspects of ethical requirements for principles with practical solutions.

Investigating Clinicians' Intentions and Influencing Factors for Using Intelligence-enabled Clinical Decision Support Systems in Healthcare Systems：Cross-sectional Survey (Preprint)
Authors: Zheng Rui , Jiang Xiao , Shen Li , Ji Mengting , He Tianrui , Li Xingyi , Yu Guangjun
Published: June 2024

BACKGROUND

Intelligence-enabled clinical decision support systems (CDSS) are sophisticated software systems designed to assist healthcare providers in making clinical decisions by leveraging various forms of intelligence. Research studies have shown that CDSS utilization rates have not met expectations. Clinicians' intentions and their attitudes determine the use and promotion of CDSS in clinical practice.

OBJECTIVE

The aim of this study was to enhance the successful utilization of CDSS by analyzing the pivotal factors that influence clinicians' intention to adopt it and by putting forward targeted management recommendations.

METHODS

This study proposed a research model grounded in the Task-Technology Fit (TTF) model and the Technology Acceptance Model (TAM), which was then tested through a cross-sectional survey. The measurement instrument comprised demographic characteristics, multi-item scales, and an open-ended query regarding areas where clinicians perceived the system required improvement. We leveraged structural equation modeling to assess the direct and indirect effects of “Task-Technology Fit” and “Perceived Ease of Use” on clinicians’ intention to use the CDSS when mediated by“Performance Expectation” and “Perceived Risk”. We collated and analyzed the responses to the open-ended question.

RESULTS

We collected a total of 247 questionnaires. The model explained 65.8% of the variance in use intention. Performance expectations (β=0.228; P<0.001) and perceived risk (β=-0.579; P<0.001) were both significant predictors of use intention. Task-technology fit(β=-0.281;P<0.001) and perceived ease of use(β=-0.377;P<0.001) negatively affected perceived risk. Perceived risk(β=-0.308;P<0.001) negatively affected performance expectations. Task-technology fit positively affected perceived ease of use(β=0.692;P<0.001) and performance expectations(β=0.508;P<0.001). Task characteristics(β=0.168;P<0.001) and technology characteristics(β=0.749;P<0.001) positively affected Task-technology fit. Contrary to expectations, perceived ease of use(β=0.108;P=0.073) did not have a significant impact on use intention. From the open-ended question, three main themes emerged regarding clinician’s perceived deficiencies in CDSS: system security risks, personalized interaction, seamless integration.

CONCLUSIONS

Perceived risk and performance expectations were direct determinants of clinicians' adoption of CDSS, significantly influenced by task-technology fit and perceived ease of use. In the future, increasing transparency within CDSS, fostering trust between clinicians and technology should be prioritized. Furthermore, focusing on personalized interactions and ensuring seamless integration into clinical workflows are crucial steps moving forward.

Feminist Resistance in Tehmina Durrani’s “My Feudal Lord”
Authors: Joshi Somya
Published: June 2024

The paper aims to highlight the quiet, yet persistent, feminist resistance that can bloom even within the confines of a patriarchal, feudal society. Narrating her life as the wife of a powerful Pakistani feudal lord Mustafa Khar, Durrani lays bare the systemic oppression faced by women in this milieu: physical and emotional abuse, social ostracization, and a denial of basic rights. She speaks out against the sexual exploitation that is rampant within the confines of marriage, wherein women are often treated as only objects of pleasure and are considered to be suitable for childbearing purposes. However, resistance simmers beneath the surface. Durrani's defiance manifests in subtle acts of rebellion – intellectual pursuits, questioning societal norms, and even voicing her discontent to her husband. This defiance, though often silenced or met with violence, lays the groundwork for her eventual escape from the suffocating confines of her marriage. Through her raw honesty and unflinching portrayal of female subjugation, Durrani challenges the status quo and becomes a powerful voice for feminist liberation. Durrani is ostracized from her family and the Pakistani society for speaking out against her powerful husband and encouraging other women to speak up against the injustices they face. The narrative transcends personal experience, offering a glimpse into the collective struggle of women trapped within similar structures of oppression, ultimately urging readers to question and dismantle these systems.
