Inductorless Cascaded Low-Power Dc-Dc Converter: Optimizing Performance Metrics Through Machine Learning Techniques, Ahmed Khaled, Sameh O. Abdellatif

Electrical Engineering

This study presents a groundbreaking methodology for optimizing the operational efficiency of a three-stage boost DC-DC cascaded converter through the application of a Random Forest(RF) machine learning algorithm. A novel figure of merit is meticulously formulated to quantitatively evaluate the converter’s performance, focusing on critical metrics such as power conversion efficiency, output DC ripple levels, and response time. The Random Forest model is trained on a comprehensive dataset encompassing a wide range of resistive and capacitive design parameters, with the figure of merit serving as the output indicator. Rigorous simulations and analyses demonstrate that the integration of LM741 operational amplifiers …

Safe Sex In The Age Of Big Tech Feminism, Brenda Dvoskin, Thomas E. Kadri

Articles

Lawmakers and technology companies are regulating online sexuality in the name of feminism. Whereas libertarian ideals dominated early debates about internet governance, "safety" has become the rallying cry to regulate online activity in the age of Big Tech. Legislators across the political spectrum and companies around the world are devising interventions meant to keep people - and especially women safe from the risks of online sexuality. Through law and technology, they target everything from privacy invasions to unwanted messages to sexual deepfakes. We call this regulatory and ideological trend Big Tech feminism.

This Article interrogates the feminist strands animating Big …

​​​How Do Working Conditions Effect Teacher Job Satisfaction And Intention To Stay: Retaining Special Education Teachers​, Alyssa Michelle Raygoza

Theses and Dissertations

Teacher retention remains a leading area of focus in the United States. Recent research efforts have examined the effects of specific work-related experiences on teacher retention. In comparison to teaching in a general education classroom, special education teachers often face increased levels of job demands that can influence the ways in which existing resources may or may not balance out such challenges. The study is grounded in the Job Demands-Resources (JD-R) Model, a theoretical framework that has been used widely in both occupational and, more recently, educational research focusing on the specific demands and resources situated within teacher working conditions. …

Influence Of School Climate On Comprehensive School Behavioral Health Effectiveness, Halle Rose Singer

Theses and Dissertations

Youth are experiencing a sharp rise in mental health concerns, which have reached critical levels. Schools have emerged as a key setting for delivering mental health services due to their accessibility, familiarity, and capacity to reach diverse populations. Comprehensive School Behavioral Health (CSBH) systems offer a multi-tiered, evidence-based framework for supporting the mental health of all students. However, the success of CSBH interventions varies across schools presumably indicating that systemic or school level factors, like school climate, may influence youth mental health outcomes. In this study, I investigate how school-level factors, specifically student-perceived school climate, influence the mental health outcomes …

Cultural Diagnosis And The Monsters Of Victorian England, Victoria Elizabeth Kuykendall

Theses and Dissertations

This dissertation examines the representation of invisible disability and neurodivergence in nineteenth-century British literature, arguing that literary texts both reflect and shape cultural understandings of disability. While much scholarship has focused on visible or physical impairments in Victorian fiction, comparatively little attention has been given to characters whose behaviors, emotions, or identities align with what today might be described as neurodivergence.

Drawing on Disability Studies, Mad Studies, and cultural theory, I propose the concept of cultural Diagnosis as a framework for analyzing how fictional characters become “Diagnosable” within both their historical and contemporary cultural contexts. Through close readings of Arthur …

Woman, Motherhood, And Home: Grappling With Gendered Dwelling, Pamela Joy M. Capistrano

Philosophy Department Faculty Publications

Though ostensibly gender neutral, the word “home” carries with it the baggage of gender, particularly womanhood and motherhood. In English, for instance, “homemaking” is synonymous with “housewifery;” in Filipino, the mother is described as ilaw ng tahanan (“light of the home”). Housing, as well, has a similar neutral connotation; yet, when we consider the impact of urban housing crises, women are disproportionately affected. In this paper, I want to grapple with the broader implications of the gendered baggage of the idea of “home,” its impact on individuals, on how we conceive of houses, homes, and dwellings, and ultimately its impact …

Exploring Dynamics Of Nature’S Raincoat: Comparing How Nano-Scale Silk Fibers Produced By Dryland And Tropical Species Of Webspinning Insects Interact With Water, Richard P. Barber Jr, Emily A. Arias, Andrew M. Schatz, Aidan Kaneski, Janice Edgerly-Rooks

Biology

Embiopterans are reliant on silk for protection and produce the finest silk fibers known in nature. This report compares silk–water interactions for four species representing two different lifestyles: two tropical arboreal species that feed on lichens on bark and two detritivores from arid regions that typically live in leaf litter and underground. Water droplets placed on spun silk transformed the fibrous top layer to a film. Arboreal embiopterans spun a denser silk covering than did the detritivores. The films that formed after exposure to water were also denser for the arboreal species. A possible underlying cause for the difference between …

Theses and Dissertations

The present study examined the ability of younger and older adults to prioritize one task over another under divided attention conditions. The speech task involved the repetition of sentences that included specific vowel targets, and the non-speech task was a visuomotor pursuit rotor task which required tracking a moving target on a computer. The participants were twenty young adults between the ages of 18 and 30 and twenty older adults above the age of 60. They performed each task on its own and both tasks concurrently, prioritizing one or the other task. Audio recordings were analyzed with software to extract …

Detection Of Malicious Office Document Macros Using Large Language Models, Mahesh Kalappattil

Masters Theses & Doctoral Dissertations

Microsoft office document malwares are prevalent today even though some of the macros were developed 30 years ago. The office macros are used as droppers or downloaders for emerging malwares. Though various models have been developed to detect the office document macros, the interpretability and attribution of the model results are not gained attention. Also, even though the models provide high accuracy, the probabilistic uncertainty the models are not addressed either.

This research provides a novel method to classify malicious office document macros measuring interpretability, attribution and probabilistic uncertainty. Our approach combines the function semantics and keyword contexts to leverage …

Advancing Cybersecurity Assurance: A Novel Outcome-Based Approach For Evaluating Cybersecurity Controls, Yousuf M. Muhammad

Masters Theses & Doctoral Dissertations

The growing frequency and complexity of cyberattacks pose a serious and escalating risk to both individuals and organizations. Current cybersecurity assurance approaches often fall short in effectively measuring the adequacy of cybersecurity controls in terms of mitigating risks and providing measurable value to organizations. The current approaches are often focused on measuring compliance with predetermined requirements as defined in government regulation or an industry standard, thereby overlooking the need for a holistic approach that incorporates all aspects of security. This dissertation is an attempt to address this gap by developing a novel outcome-based cybersecurity assurance approach.

The research problem focused …

First-Year University Students’ Mathematics Capital And Identities, Paola Valero, Lisa Österling, Nhu Truong, Anna Danielsson, Bruna Nunes, Maria Berge

The Mathematics Enthusiast

Based on a survey of 150 respondents and 16 timeline interviews with first-year university mathematics students in Sweden, we explore how the material resources and conditions available to them —mathematics capital— connect to their mathematical identities. We found that mathematics capital has bearing on how early in life students start to consider doing mathematics. We also found individually different trajectories among students with low mathematics capital into university mathematics. The study expands both existing theoretical and methodological ways of researching the material bearings of identity and opens up for new ways of understanding and exploring the conditions that may facilitate …

From Problem Solving To Problem Posing: Two Classroom Examples, Suzana Antunović, Ljiljana Arambašić, Anđa Valent

The Mathematics Enthusiast

In this paper, we present two examples of classroom activities on divisibility and mathematical induction that combine problem solving and problem posing. In our activities, standard tasks of the form ’Prove that the statement holds’ were transformed into ’Think of similar examples,’ with the meaning of ’similar’ left for the students to interpret. This approach not only helps develop problem-solving skills but also teaches students how to pose problems themselves.

Carbon Footprint Of Carrots In Western Australia, Christophe D'Abbadie, Saloomeh Akbari, Sang Ravindran

Horticulture research reports

This report presents the findings of a comprehensive carbon accounting study conducted on carrot production in the Myalup area of Western Australia.

The study reveals that carrot emissions are approximately 81 kg CO2e per tonne of carrot sold from the April harvest and 76 kg CO2e per tonne from the October harvest, when using rejected carrots for other economic uses. These figures represent competitive emissions intensities compared to international benchmarks.

Key findings include:

• Yield improvement is the primary driver for emissions reduction: Increasing productivity, without proportional input increases, offers the most effective pathway to lower emissions’ intensity while improving economic …
