Power Saving In Open Ran By Using Advanced Cpu Scheduling Algorithm, Saish Urumkar, Sachin Sharma Jan 2025

Power Saving In Open Ran By Using Advanced Cpu Scheduling Algorithm, Saish Urumkar, Sachin Sharma

Conference papers

Open RAN is an emerging wireless technology that is gaining significant attention for its potential to enable flexi- ble, cost-efficient, and interoperable networks. Reducing power utilization in Open RAN, particularly for 5G base stations (gNodeBs) deployed in remote areas, remains a critical challenge due to limited power availability. In our previous work, we developed a CPU scheduling algorithm that optimized core allocation based on load conditions, reducing power utilization for gNodeB in a virtualized Open RAN environment. Extending our previous work, this paper introduces an advanced CPU scheduling for Open RAN designed to reduce power utilization in real hardware Open …

Extreme Value Theory Analysis Of High Emitter Trends Across Four Us Cities From 1995 To 2021, M. Matti Maricq, Gary A. Bishop Jan 2025

Extreme Value Theory Analysis Of High Emitter Trends Across Four Us Cities From 1995 To 2021, M. Matti Maricq, Gary A. Bishop

Fuel Efficiency Automobile Test Publications

Extreme value theory provides a direct means to characterize the distribution of high emitters within a vehicle fleet and calculate statistical confidence intervals for comparisons. Defining a “high emitter” as the maximum emitter in a random sample of N vehicles implies in the limit of large N that high emitters follow an extreme value distribution, comprised of three distinct domains. The analysis of over twenty years of roadside remote sensing emissions measurements in Chicago, Denver, Los Angeles and Tulsa reveals clear differences between gasoline vehicle high emitter distributions across pollutants (hydrocarbons (HC), carbon monoxide (CO) and nitric oxide (NO)), but …

Mesoscale Modelling For Investigating Effective Properties And Collective Performance Of Geopolymer Concrete, Feiyu Shi Jan 2025

Mesoscale Modelling For Investigating Effective Properties And Collective Performance Of Geopolymer Concrete, Feiyu Shi

School of Engineering, Computing and Mathematics Theses

Concrete is a versatile construction material which, depending on architectural design and structural analysis, can be shaped into various forms so that requirements for beauty and functions of designed facilities can be met while structural strength of the facilities is sufficient to sustain both gravity and external loadings. It is so favoured by engineers that its consumption is just after water. However, Portland cement – a main ingredient for use in the manufacture of traditional concrete – is quite a “dirty” material which releases a large amount of carbon dioxide in the process of its production. Carbon dioxide is one …

Metamorphosis: An Evaluation Of The Adaptation And Re-Use Potential Of Suburban Housing For Older Homeowners, Michelle Moore Jan 2025

Metamorphosis: An Evaluation Of The Adaptation And Re-Use Potential Of Suburban Housing For Older Homeowners, Michelle Moore

Masters

Ireland’s population is ageing at a rate that is more than twice the EU average. Public policy in Ireland aims to support older persons to age-in-place. Over 80% of older adults in Ireland live in an owner-occupied home, following many decades of public policy promoting home ownership as the tenure of choice. Limited research has been undertaken on the housing adaptation options that could result in privately-owned homes being made more suitable for the evolving needs of the rapidly ageing demographic. This thesis addresses the hypothesis that, with the provision of an appropriate suite of enablers, older homeowners can be …

Electrochemical Detection Of Nitrite Based On Iron Oxide–Reduced Graphene Oxide Nanocomposite Modified Electrode In Real Water, Amira Ghezal, Zina Fredj, Ammar Al-Hamry, Marcos A. Gross, Leonardo G. Paterno, Mounir Ben Ali, Olfa Kanoun, Baljit Singh Jan 2025

Electrochemical Detection Of Nitrite Based On Iron Oxide–Reduced Graphene Oxide Nanocomposite Modified Electrode In Real Water, Amira Ghezal, Zina Fredj, Ammar Al-Hamry, Marcos A. Gross, Leonardo G. Paterno, Mounir Ben Ali, Olfa Kanoun, Baljit Singh

Research Outputs: 2025-Present

This work presents a screen-printed carbon electrode (SPCE) modified with iron oxide nanoparticles-reduced graphene oxide (ION-rGO) nanocomposite for the rapid and highly sensitive determination of nitrite in real water samples. The presence of both ION and rGO on the electrode surface enhances the sensing performance compared to the unmodified SPCE by reducing the charge transfer at the electrode/electrolyte interface. Under optimized conditions, it is demonstrated that the charge-transfer resistance determined from electrochemical impedance spectroscopy (EIS) scales linearly with the logarithm of nitrite concentration. Due to its unique structure, the proposed nitrite sensor displays improved performance compared to our previous work, …

Exploring The Sustainability Of Single Use Plastics In The Biopharmaceuticals Sector: A Scoping Review Of Challenges, Opportunities And Impact, Cormac Mcmahon, Adrienne F. M. Fleming, Philip Owende, Malcolm Goggin Jan 2025

Exploring The Sustainability Of Single Use Plastics In The Biopharmaceuticals Sector: A Scoping Review Of Challenges, Opportunities And Impact, Cormac Mcmahon, Adrienne F. M. Fleming, Philip Owende, Malcolm Goggin

Articles

Single-use plastics (SUPs) are synonymous with the biopharmaceuticals sector, facilitating economies of scale, process efficiency, flexibility and sterility assurance, all with a seemingly negligible environmental footprint. Yet, in ever-tightening regulation, mandated by the Sustainable Development Goals (SDGs) and by concern for large-scale industrial impacts, the sustainability of SUP consumption is increasingly being questioned. Whilst the sector contributes to human welfare, its transition risk is unlikely to remain immune to societal pressure for more sustainable production. This paper aims to present a scoping review of the apparent contradiction between sectoral SUP adoption and the increasing importance of circularity. The approach to …

Social media platforms are an integral part of daily life for nearly five billion people worldwide. However, the growing presence of underage users on these platforms raises significant concerns regarding children's exposure to harmful content and its impact on their mental health. This paper examines the effectiveness of age verification measures implemented on leading platforms Facebook, YouTube, Instagram, TikTok, Snapchat, and X. We evaluate the age verification processes required for account creation by simulating the registration steps for minors on these platforms. We also compare these methods to best practices in online age assurance in finance, betting and public transportation …

Synthesising Cross-Speaker Data For Low-Resource Pathological Speech Recognition With Peft, Kesego Mokgosi, Milad Dadgar, Cathy Ennis, Robert Ross Jan 2025

Synthesising Cross-Speaker Data For Low-Resource Pathological Speech Recognition With Peft, Kesego Mokgosi, Milad Dadgar, Cathy Ennis, Robert Ross

Conference papers

Dysarthric speech recognition is essential for enhancing communication and accessibility for individuals with speech impairments, yet its development is hindered by a scarcity of robust, speaker-specific datasets. This study explores low-resource dysarthric speech recognition through cross-speaker transfer using synthetic data and parameter-efficient fine-tuning (PEFT). We integrate SpeechT5 text-to-speech (TTS) synthesis with x-vector speaker embeddings to generate speaker-specific dysarthric speech, enabling model adaptation while preserving pathological speech characteristics such as prosodic irregularities. Experiments on the TORGO dataset show that mixed cross-synthetic data with LoRA fine-tuning achieves a WER of 0.17, representing a 71.7% improvement over the standard model (0.60 WER) without …

Evaluation Of Processing Conditions For The Reduction Of Electrochemical Salt Waste Using Phosphate-Based Dechlorination, Harmony Werth, Jade Beland, Paige Murray, Dave Liang, Laurel Sharpless, Jonathan Evarts, Charmayne Lonergan, Brian J. Riley, Michael Simpson, Krista Carlson

Materials Science and Engineering Faculty Research & Creative Works

Electrochemical processing of used nuclear fuel in molten chloride salts generates complex radioactive salt waste. Dechlorination of waste salt using phosphate compounds at elevated temperatures (∼600 °C) reduces the volume of material for disposal while evolving gaseous chlorine compounds that could be used to transform metallic uranium into UCl3. In this study, the effects of processing temperature, environment (air or argon), and H3PO4 precursor-to-chlorine ratio on the dechlorination efficacy of a simple alkali salt mixture (SSM) and a salt waste simulant (ERV3) were evaluated. For both salts, the highest chlorine release was concurrent with the water boiling. For the SSM, …

Socioeconomic Status And Educational Opportunities Through The Eyes Of Students And Teachers: Diverse Realities, Shared Insights, Jill Schany Jan 2025

Socioeconomic Status And Educational Opportunities Through The Eyes Of Students And Teachers: Diverse Realities, Shared Insights, Jill Schany

Dissertations and Theses @ UNI

Sowl and Crain (2021) argue that despite recognizing the uniqueness of the place when it comes to rural demographics and needs, policies regarding education and the economy often prioritize urban areas, defining rural in opposition to urban without adequately addressing the specific needs of rural youth. Studies examining geographical disparities in educational outcomes traditionally concentrated on achievement gaps within urban and suburban areas, highlighting more startling gaps in cities with heightened racial, ethnic, and socioeconomic inequality and segregation. Literature also extensively discusses neighborhood effects on educational outcomes in densely populated regions, offering valuable insights into the distribution of educational opportunities …

Encapsulating Student Perspectives: Investigating Students’ Voice In Urban Secondary Education, Treyvon L. Harlin Jan 2025

Encapsulating Student Perspectives: Investigating Students’ Voice In Urban Secondary Education, Treyvon L. Harlin

Wayne State University Dissertations

ABSTRACTEncapsulating Student Perspectives: Investigating Students’ Voice in Urban Secondary Education by Treyvon L. Harlin February 2025 Advisor: Ben Pogodzinski, Ph.D. Major: Educational Leadership and Policy Studies Degree: Doctor of Philosophy The research in this dissertation focuses on the implication of student voice in historically marginalized secondary schools throughout the metropolitan area of Detroit, Michigan. Research initiatives conducted by Delpit (2006), Holmes & Crossley (2004), and Levitan (2018) have shown that students, especially those of marginalized populations, must have a sense of safety, feel valued and that their opinions matter to have buy-in with academic objectives and a school’s vision. Unfortunately, …

Agency, Index & Process: Investigating The Role Of The Artist’S Body In Digital Sculpture Production, Alan Magee Jan 2025

Agency, Index & Process: Investigating The Role Of The Artist’S Body In Digital Sculpture Production, Alan Magee

Doctoral

Contemporary Digital Sculpture has emerged out of recent developments in digital art, 3d modelling and virtual modes of production. These advances range from the creation of more powerful software and hardware systems to the to nascent XR sectors, and the potential for materialisation through technologies such as 3d printing, laser-cutting, or CNC1 machining. However, critical discourse remains predominantly focused on the end product, often overlooking the embodied labour processes inherent in its creation. As revealed through indexical traces of the artist’s body, these processes encapsulate the gestures, actions and subjective agency of artistic activity. Consequently, with the limitations of digital …

Public Art Coordination: Shaping The Irish Arts Landscape, Jennifer Haughton Jan 2025

Public Art Coordination: Shaping The Irish Arts Landscape, Jennifer Haughton

Doctoral

Appointing public art coordinators responsible and accountable for programming and commissioning in the public sphere is a growing trend internationally. My aim in this PhD thesis is to undertake an inquiry into the practice of how public art coordination facilitates artists in producing ambitious public art works. Appropriating Mary Parker Follett’s (1866–1933) concept of multiple leadership in addition to curatorial, rights, and management theory, I argue for an increased accommodation of public art coordination as a public leadership service arising from the construction sector. Adopting Ricoeurian hermeneutics alongside vignettes, my thesis constitutes a deep dive into the habitat and culture …

Mapping Engineering Ethics Education, R Tormey, T Børsen, Shannon Chance, T T Lennerfors, Diana Adela Martin, G Bombaerts

Research Outputs: 2025-Present

Writing a handbook implies describing the fundamental information needed by those teaching or researching in a field. This is a challenging task when the field is still maturing. This handbook grew from the idea that we could ‘collaboratively write’ engineering ethics education. In this introduction, we define the field in three dimensions: engineering, ethics, and education. The latter dimension is divided into three parts: the subjects that shape the teaching of engineering ethics education, the understanding of learners and learning that informs the pedagogical choices made, and the fusion of these two in the pedagogical methods used in teaching engineering …

Policy And Poppycock In Proximate Cause Cases A/K/A Scope Of Liability And Starting To Make Sense, Thomas Galligan Jan 2025

Policy And Poppycock In Proximate Cause Cases A/K/A Scope Of Liability And Starting To Make Sense, Thomas Galligan

FIU Law Review

Studying proximate cause is like trying to decode mumbo jumbo. Courts continue to use words like direct, remote, natural and probable, foreseeable, hindsight, and intervening and superseding causes, and they make them sound like tests. They make them sound like law. Furthermore, as one test is debunked and another appears, courts continue to apply the debunked tests. They just pile on a new one as well. Then, they calm themselves and say that proximate cause is all a matter of policy. After all, Leon Green said that; William Prosser said that. It must be true. But courts fail to ever …

The Interchangeable-Part Structure Of Food And Drug Law, Adam I. Muchmore Jan 2025

The Interchangeable-Part Structure Of Food And Drug Law, Adam I. Muchmore

FIU Law Review

This Article demonstrates that nested tiers of interchangeable parts serve as the foundation for the regulatory programs administered by the U.S. Food and Drug Administration. Core interchangeable parts used in FDA-administered programs include product categories, prohibitions on adulteration and misbranding, agency-registration requirements, current good manufacturing practices, product standards, marketing authorization requirements, postmarket requirements, and user fees. In each of these areas, Congress or the FDA has engaged in interchangeable-part lawmaking (IPL). IPL occurs when a government takes a portion of its law in one subject area and uses it as a model for its own law in another subject area. …

“Modernizing Regulatory Review”: A Short-Lived Abandonment Of More Than Four Decades Of Regulatory Review And Benefit-Cost Analysis, Richard Belzer Jan 2025

“Modernizing Regulatory Review”: A Short-Lived Abandonment Of More Than Four Decades Of Regulatory Review And Benefit-Cost Analysis, Richard Belzer

FIU Law Review

"President Biden’s Modernizing Regulatory Review (MRR) initiative fundamentally altered regulatory procedures, practices, and centralized oversight that had been in place since 1981 when they were formalized by President Reagan in Executive Order 12,291. MRR proceeded in three phases. First, a Memorandum issued on President Biden’s first day in office telegraphing the broad outlines of the plan. Second, more than two years later, an Executive Order codifying the MRR memorandum was issued, combined with implementation guidance issued by the Office of Management and Budget (OMB). And third, OMB guidance on the conduct of regulatory BCA was radically revised, clearly with an …

Free Movement Rights And The American City, Ryan Stoa

FIU Law Review

American cities are facing an inflection point. Widespread dissatisfaction with urban planning outcomes is making land use and transportation policies (such as congestion pricing) a mainstream topic of debate. Suburban sprawl and housing shortages are moving urban populations into the periphery, commuting times (and associated mental health problems) are increasing, and pedestrian and cyclist deaths caused by vehicles are at all-time highs. American cities that were largely planned and built in the twentieth century based on assumptions that we now know are flawed are not meeting the needs of their residents, and urban planners are making changes to reshape urban …
