Extraction Of Stripline Surface Roughness Using Cross-Section Information And S-Parameter Measurements, Zeyi Sun, Jian Liu, Xiaoyan Xiong, Victor Khilkevich, Donghyun Kim, Darvl Beetner

Engineering Management and Systems Engineering Faculty Research & Creative Works

To characterize additional conductor loss introduced by conductor surface roughness, various models have been proposed to describe the relationship between foil roughness levels and surface roughness correction factor. However, all these empirical or physical models require a PCB sample to be manufactured and analyzed in advance. The procedure requires dissecting the PCB and is time- and labor-consuming. To avoid such a process, a new surface roughness extraction process is proposed here. Only the measured S-parameter and nominal cross-sectional information of the board are needed to extract the roughness level of conductor foils. Besides, this method can also deal with boards …

Maintenance Optimization In A Digital Twin For Industry 4.0, Abhijit Gosavi, Vy Khoi Le Jan 2022

Maintenance Optimization In A Digital Twin For Industry 4.0, Abhijit Gosavi, Vy Khoi Le

Engineering Management and Systems Engineering Faculty Research & Creative Works

The advent of Internet of Things and artificial intelligence in the era of Industry 4.0 has transformed decision-making within production systems. In particular, many decisions that previously required significant human activity are now made automatically with minimal human intervention via so-called digital twins (DTs). In the context of maintenance and reliability modeling, this naturally calls for new paradigms that can be seamlessly integrated within DTs for decision-making. The input data for time to failure needed in reliability computations are directly collected from the work center in a digital setting and often do not satisfy a known distribution. A neural network …

Identifying Industry 5.0 Contributions To Sustainable Development: A Strategy Roadmap For Delivering Sustainability Values, Morteza Ghobakhloo, Mohammad Iranmanesh, Muhammad Faraz Mubarak, Mobashar Mubarik, Abderahman Rejeb, Mehrbakhsh Nilashi Jan 2022

Identifying Industry 5.0 Contributions To Sustainable Development: A Strategy Roadmap For Delivering Sustainability Values, Morteza Ghobakhloo, Mohammad Iranmanesh, Muhammad Faraz Mubarak, Mobashar Mubarik, Abderahman Rejeb, Mehrbakhsh Nilashi

Research outputs 2022 to 2026

Scholars believe that the newly introduced Industry 5.0 has the potential to move beyond the profit-centered productivity of Industry 4.0 and to promote sustainable development goals such as human-centricity, socio-environmental sustainability, and resilience. However, little has been done to understand how this ill-defined phenomenon may deliver its indented sustainability values despite these speculative promises. To address this knowledge gap, the present study developed a strategy roadmap that explains the mechanism by which Industry 5.0 delivers its intended sustainable development functions. The study first developed and introduced the Industry 5.0 reference model that describes the technical and functional properties of this …

Understanding And Treating Suboptimal Health Status Through Tourism Engagement: An Exploratory Study Of Chinese Domestic Tourists, Jun Wen, Danni Zheng, Ian Phau Jan 2022

Understanding And Treating Suboptimal Health Status Through Tourism Engagement: An Exploratory Study Of Chinese Domestic Tourists, Jun Wen, Danni Zheng, Ian Phau

Research outputs 2022 to 2026

Objectives: Suboptimal health status (SHS) is a global public health concern of worldwide academic interest. The topic is popular in the medical sciences, including public health; however, other disciplines have paid little attention to this condition despite aging societies. This study introduced SHS into the tourism literature, a logical connection given the established positive correlation between well-being and tourism engagement. Lifestyle factors are crucial to SHS. Accordingly, this study examines tourists’ sociodemographic characteristics, tourism-related attributes, and lifestyle behaviors to compare individuals with SHS to those with optimal health status. Methods: Chinese tourists in Shandong Province, China who had visited Mount …

The Intersection Of The Rule In Yerkey V Jones And Contemporary Anti-Discrimination Law In Australia – Can The ‘Special Wives’ Equity Survive?, Kenneth Yin, Mostafa M. Naser Jan 2022

The Intersection Of The Rule In Yerkey V Jones And Contemporary Anti-Discrimination Law In Australia – Can The ‘Special Wives’ Equity Survive?, Kenneth Yin, Mostafa M. Naser

Research outputs 2022 to 2026

The High Court in Yerkey v Jones considered the enforceability of a guarantee provided by a married woman to secure her husband’s debts. Dixon J said that although the relationship of husband and wife did not give rise to a presumption of undue influence, the law had never been divested completely of ‘the equitable presumption of an invalidating tendency’. Dixon J’s formulation was essentially adopted by the majority justices in Garcia v National Australia Bank and their judgment thus represents the definitive endorsement of Dixon J’s view. Kirby
J on the other hand rejected ‘the stereotype underlying Yerkey’, which he …

Online Brand Detraction In An Online Opinion Platform, Violetta Wilk, Claire Lambert, Stephanie Meek Jan 2022

Online Brand Detraction In An Online Opinion Platform, Violetta Wilk, Claire Lambert, Stephanie Meek

Research outputs 2022 to 2026

While most studies focus on positive consumer-driven brand outcomes, this study set out to understand a negative consumer-driven brand outcome - online brand detraction (OBD). Through the lens of social exchange theory, OBD was operationalized and compared to its direct opposite manifestation - online brand advocacy (OBA). A big data, qualitative analysis, with a longitudinal approach was used to understand OBD in an online opinion platform (OOP). Four key dimensions of OBD were found: brand negativity, brand attack, negative brand knowledge and experience sharing, and virtual visual cues. These dimensions are polar opposites of OBA - a highly sought-after organic …

Proportional Fair Clustered Federated Learning, Mohamed Nafea, Eugine Shin, Aylin Yener Jan 2022

Proportional Fair Clustered Federated Learning, Mohamed Nafea, Eugine Shin, Aylin Yener

Electrical and Computer Engineering Faculty Research & Creative Works

This paper studies federated learning (FL) with non-identical data generating distributions and under the notion of proportional fairness. Users are partitioned into disjoint clusters based on their data distributions, and a distinct model is learnt for each cluster. Different than previous work that considered clustering to optimize personalized learning performance, here clustering is inspected under the disparate impact doctrine which requires that protected classes (e.g., those of certain race or gender) have representations in every cluster that are approximately equal to their representation in the overall set of users. A family of iterative algorithms that balance the learning performance and …
