Thermal Image-Based Fault Diagnosis in Induction Machines Via Self-Organized Operational Neural Networks
No full textCondition monitoring of induction machines is crucial to prevent costly interruptions and equipment failure. Mechanical faults such as misalignment and rotor issues are among the most common problems encountered in industrial environments. To effectively monitor and detect these faults, a variety of sensors, including accelerometers, current sensors, temperature sensors, and microphones, are employed in the field. As a non-contact alternative, thermal imaging offers a powerful monitoring solution by capturing temperature variations in machines with thermal cameras. In this study, we propose using 2dimensional Self-Organized Operational Neural Networks (SelfONNs) to diagnose misalignment and broken rotor faults from thermal images of squirrel-cage induction motors. We evaluate our approach by benchmarking its performance against widely used Convolutional Neural Networks (CNNs), including ResNet, EfficientNet, PP-LCNet, SEMNASNet, and MixNet, using a Workswell InfraRed Camera (WIC). Our results demonstrate that Self-ONNs, with their non-linear neurons and self-organizing capability, achieve diagnostic performance comparable to more complex CNN models while utilizing a shallower architecture with just three operational layers. Its streamlined architecture ensures high performance and is well-suited for deployment on edge devices, enabling its use also in more complex multi-function and/or multi-device monitoring systems. © 2025 IEEE

No full textThe actor-spectator divide in Hannah Arendt's theory of judgment remains one of the most contested issues in the secondary literature. Scholars have long debated the tension between judgment as a retrospective faculty tied to the spectator's gaze and its potential as a forward-looking guide for action. This divide encapsulates the dual character of judgment, with critics highlighting the apparent contradiction between its political application in Arendt's early works and its contemplative focus in her later thought. At the heart of these debates lies the unresolved question of how judgment transitions from being an essential component of political action to a solitary, reflective activity. This thesis seeks to address this enduring controversy by tracing the origins and reasons behind this shift in Arendt's conception of judgment. It explores the introduction of the faculty of the will and its impact on the functions that had hitherto been assigned to judgment. Specifically, the thesis argues that this transformation arises from Arendt's reconfiguration of the mental faculties, particularly the relegation of the power of choice—initially assigned to judgment—to the will. By examining key texts, including Between Past and Future, Freedom and Politics, Some Questions of Moral Philosophy, and The Life of the Mind, this study identifies the critical junctures in Arendt's thought and provides a comprehensive analysis of the philosophical motivations underlying this evolution. Through this, it aims to illuminate the broader implications of the actor-spectator divide and its centrality to Arendt's unfinished project on judgment.Hannah Arendt'in yargı teorisindeki 'aktör-seyirci' (actor-spectator) ayrımı, ikincil literatürde en çok tartışılan meselelerden biri olmaya devam etmektedir. Akademisyenler, yargının retrospektif bir yeti olarak izleyicinin bakışına bağlı kalırken, geleceğe yönelik bir rehber olma potansiyeli taşıyan eylemsel işlevi arasındaki gerilimi uzun süredir tartışmaktadır. Bu ayrım, Arendt'in düşüncesinde yargının hem siyasi hem de zihinsel bir etkinlik olarak çift yönlü karakterini temsil eder. Eleştirmenler, bu gerilimin Arendt'in düşüncesinin Zihnin Yaşamı (The Life of the Mind) bağlamında, vita activa'dan vita contemplativa'ya geçişi sırasında yaşanan değişimi yansıttığını savunmaktadır. Bu tez, yargı anlayışındaki bu değişimin kökenlerini ve nedenlerini tespit etmeyi amaçlamaktadır. Yargıya özgü işlevlerin, Arendt'in zihinsel yetiler ailesine istenç (will) yetisinin eklenmesiyle nasıl dönüştüğünü araştırmaktadır. Tez, yargının temel işlevlerinden biri olan 'seçim gücü'nün istenç yetisine devredilmesinin bu değişimin merkezinde yer aldığını savunmaktadır. Geçmişle Gelecek Arasında, Özgürlük ve Politika, Bazı Ahlak Felsefesi Soruları ve Zihnin Yaşamı gibi temel metinler ışığında, bu çalışma Arendt'in düşüncesindeki bu dönüşümün felsefi motivasyonlarını inceleyerek, aktör-seyirci ayrımının onun yargı teorisindeki temel rolünü ve çözülmemiş gerilimlerini aydınlatmayı hedeflemektedir
Analysis of the Highest Altmetrics-Scored Articles in Emergency Medicine Journals
No full textGottlieb, Michael/0000-0003-3276-8375Introduction: Alternative metrics (altmetrics) have emerged as invaluable tools for assessing the influence of scholarly articles. In this study we aimed to evaluate correlations between Altmetric Attention Scores (AAS), and sources and actual citations in articles displaying the highest AAS within emergency medicine (EM) journals. Methods: We conducted an analysis of EM journals listed in the Science Citation Index Expanded (SCIE) using the Altmetric Explorer tool. We analyzed the journals that received the highest number of mentions, the sources of AAS, the regions most frequently mentioned, and the geographical distribution of mentions. In the subsequent stage of our analysis, we conducted an examination of the 200 top- ranked articles that had received high AAS and were published in SCIE EM journals from January 1, 2013-January 1, 2023. We sought to determine the correlations between the AAS and the citation counts of articles on Google Scholar and the Web of Science (WOS). Results: Of 40,840 research outputs evaluated, there were 510,047 shares across multiple platforms. The AAS were present for 36,719 articles (89.9%), while 10.1% had no score. In the review of the top 200 articles with the highest AAS, the median score was 382.5 (interquartile range 301.3-510.8). Of the research output evaluated, 38% were observational studies, 13% case reports, and 13% reviews/metaanalyses. The most common research topics were emergency department (ED) management and COVID-19. There was no correlation between AAS and WOS citation numbers (r(s) = -0.041, P = 0.563, 95% confidence interval [CI] -0.175-0.087). There was a weak correlation identified between WOS citations and mentions on X, and a moderate correlation observed for WOS citations and blog mentions (r(s) = 0.330, P .001, 95% CI 0.174 to 0.458; r(s)(2) = 0.109, and r(s) = 0.452, P .001, 95% CI 0.320-0.566; and r(s)(2) = 0.204, respectively). However, we found a strong positive correlation between WOS citations and the number of Mendeley readers (r(s) = 0.873, P .001, 95% CI 0.82-0.911, r(s)(2) = 0.762). Conclusion: While most articles in EM journals received an AAS, we found no correlation with traditional citation metrics. However, Mendeley readership numbers showed a strong positive correlation with citation counts, suggesting that academic platform engagement may better predict scholarly impact
Turkish Adaptation and Psychometric Evaluation of the Barriers to Incontinence Care-Seeking Questionnaire
No full textYakit Yesilyurt, Seda/0000-0002-2522-6474Introduction and HypothesisThis study was aimed at adapting, validating, and assessing the reliability of the Turkish version of the "Barriers to Incontinence Care-Seeking Questionnaire" (BICS-Q).MethodsOne hundred and forty-eight Turkish women with mild to moderate urinary incontinence (UI) was assessed. The adaptation process was conducted in alignment with the COSMIN guidelines: forward-backward translation, expert review, cultural adaptation, and a pilot study. For construct validity, items from the study by El-Azab and Shaaban, which measure barriers to seeking care for incontinence, were adapted to this self-reported questionnaire (BICS-Q), and their associations with the total score as well as the subscale scores of the questionnaire were evaluated. Cronbach's alpha was used for internal consistency, and the intraclass correlation (ICC) coefficient was estimated for test-retest reliability.ResultsThe psychometric analyses indicated that the Turkish BICS-Q has high internal consistency (Cronbach's alpha = 0.846) and test-retest reliability (ICC = 0.854). Item analysis revealed that each item was significantly correlated with the total score, thereby confirming construct validity. It was also found that embarrassment, financial concerns, and low expectations from medical consultation were ranked as the most important barriers to treatment.ConclusionsThis study demonstrated the applicability of the Turkish BICS-Q for both research and clinical purposes, emphasizing its role in identifying health care inequalities and guiding policy improvements for women with UI. The present validation study provides evidence that the Turkish BICS-Q is an appropriate tool for assessing barriers to incontinence care seeking that can be used to further research and interventions toward overcoming the barriers in Turkey.Open access funding provided by the Scientific and Technological Research Council of Turkiye (TUBTAK).

A Rudimentary Form of Time-Dependent Awareness in Mice
No full textKeeping track of event times and the uncertainty in the resultant representation time intervals is pivotal for adaptive decision-making and action planning. To this end, earlier experiments showed that humans and rodents can generate adaptive biases in decision-making considering their representational timing uncertainty. More recent studies showed that humans and rats can also track whether and how much one has underestimated or overestimated the duration of an event (resulting from timing uncertainty). These studies overlooked a more rudimentary form of time-dependent awareness-that is, knowing whether or not a response is emitted under temporal control. This type of dual-system control is a common feature of responses in tasks requiring animals to wait. We tested this hypothesis in C57BL/6 male mice (N = 16) that were trained to depress a lever for a minimum target duration to receive a reward. No reward was given when mice under-produced the minimum required target interval. During test trials, the rate of nose-pokes into the food hopper during a variable response window following time production was recorded. Mice nose-poked more vigorously (reflecting higher reward expectancy) following temporal productions around the target duration compared with when they underproduced the minimum target interval. This result suggests that mice can monitor whether their responses resulted from temporal control versus its failure. Our findings point to a rudimentary form of time-dependent awareness in mice.NSERC Discovery [RGPIN-2021-03334]This study was supported by an NSERC Discovery (RGPIN-2021-03334) grant to F.B
Variable Neighborhood Search-Based Algorithms for the Parallel Machine Capacitated Lot-Sizing and Scheduling Problem
No full textThis paper addresses the capacitated lot-sizing and scheduling problem on parallel machines with eligibility constraints, sequence-dependent setup times, and costs. The objective is to find a production plan that minimizes production, setup, and inventory holding costs while meeting the demands of products for each period without delay for a given planning horizon. Since the studied problem is NP-hard, we proposed metaheuristic approaches, Variable Neighborhood Search, Variable Neighborhood Descent, and Reduced Variable Neighborhood Search algorithms to analyze their performance on the problem. Initially, we presented an initial solution generation method to satisfy each period's demand. Then, we defined insert, swap, and fractional insert moves for generating neighborhood solutions. We employed an adaptive constraint handling technique to enlarge the search space by accepting infeasible solutions during the search. Lastly, we performed computational experiments over the benchmark instances. The computational results show the effectiveness of the proposed solution approaches, compared to existing solution techniques in the literature, and the improvements in various problem instances compared to the best-known results
