An Artificial Intelligence Assisted Framework For Automated Quantified Root Canal Curvature Measurement On Periapical Radiographs, Ming-Yi Chen, Shih-Lun Chen, Yu-Jen Chang, Yuan-Jin Lin, Chiung-An Chen, Tsung-Yi Chen, Kuo-Chen Li, Wei-Chen Tu, Patricia Angela R. Abu

Journal of Dental Sciences

Background/purpose: Root canal curvature is a complex anatomical variation that complicates endodontic treatments. Traditionally, dentists rely on two-dimensional periapical radiographs (PA) and manual methods to estimate curvature angles. However, this conventional approach is highly time-consuming and subjective, often leading to inconsistent measurements.

Materials and methods: This study aims to develop a fully automated, objective framework for precise angular measurement and severity grading of root canal curvature. The YOLO26n-seg model was employed to segment roots and classify single- or multi-rooted teeth from PA. Furthermore, we proposed an image processing algorithm that standardized orientation, extracted centerlines, and applied three-point circle fitting …

Numerical Study Of Air Vents Influence On Wave Forces Acting On Box-Type Bridge Girders With Cavities Under Storm Surge, Khalida H. Jihad

UNF Graduate Theses and Dissertations

Along with the continuous rise of sea level, direct interaction between elevated coastal structures, such as coastal bridges, and seawater during storm surge, has been shown to potentially cause bridge failures in the past. For example, Hurricane Irma (2017) generated storm surge levels exceeding 2-3 m in portions of South Florida, causing widespread transportation disruption including roadway washouts, erosion, and bridge approach damage along US-1 in Florida Keys. Similar failures have occurred during Hurricane Ivan (2004), where uplift forces displaced spans of the Escambia Bay Bridge, and Hurricane Ian (2022), which caused partial collapse of the Sanibel Causeway when elevated …

Suspended Futures: Exploring The Lived Experiences Of Black Adult Males Affected By Exclusionary Discipline, Tamara Jones

UNF Graduate Theses and Dissertations

Black males continue to experience exclusionary discipline at disproportionately high rates in American schools, often resulting in academic disruption and long-term educational and social consequences. While existing research had extensively documented disciplinary disparities, less attention had been given to how Black males interpret and make meaning of these experiences over time. This hermeneutic phenomenological study explored the lived experiences of Black adult males who experienced exclusionary discipline during their secondary school years and examined how they now make sense of those experiences in adulthood. Grounded in Critical Race Theory and Social Cognitive Theory, the study focused on participants’ perceptions of …

Psychological Distance And Auditor Assessment Of The Severity Of An Internal Control Deficiency, Scott C. Jackson, John D. Keyser, Douglas F. Prawitt

Faculty Publications

Auditors often underestimate the severity of internal control deficiencies, particularly when associated misstatements are immaterial. We find that auditors are more likely to correctly classify a material weakness when no misstatement information is provided than when misstatement information is available, and that this finding may unconsciously arise from auditors’ construal level in judging control deficiency severity. Through a series of experiments, we manipulate misstatement information related to an internal control deficiency designed to represent a material weakness. We hold the size of potential misstatement constant and find that auditors and graduate auditing students are less likely to correctly assess the …

Improving Efficiency In Noma Schemes Having Inter-User Interference Using Mechanism Design, Zory Marantz

Publications and Research

Modern wireless systems utilize non-orthogonal multiple access to increase their rate capacities; however, the efficiency of the individual utility defined in bits per Joule has yet to be considered. Multiple variations of non-orthogonal multiple access have the interference of the signal-to-interference-plus-noise ratio as a function of the received power from multiple other users due to code implementations that are non-orthogonal or non-ideal cancellation in successive-interference-cancellation methods. Game theoretic concepts are used to improve user bits-per-Joule performance. Previous solutions increment transmit power and are not based on closed form systematic methods. The mechanism design presented here led to a non-cooperative Nash …

Archives And Children's Knowledge, Elliott Kuecker, Ashley Rockenbach

Publications and Research

This article argues for the importance of collecting works created by children—not just about and not just for—in formal archival collections. Framed through the ideas of legitimate knowledge and epistemic injustice, this piece combines notions important to children’s rights activists and childhood studies scholars with the role archives can play in preserving children’s knowledge through child-created materials. The authors describe how researchers struggle to find work created by children within archives, impacting the ability to create child-centered research that centers children’s views of the world as prominently as adult views of the world. Some collections that do include child-created materials …

Ancient Wisdom & Its Cultural Relevance: Reimagining Deeper Learning In Science Classrooms Through The Lens Of Yoga And Vedānta, Raaghav Pandya

Publications and Research

Contemporary calls to reconceptualize how science is taught and understood have brought deeper learning to the forefront of education at-large for its emphasis on critical perspectives, creativity, and student-centered inquiry. Yet this paper argues that its prevailing framework remains constrained by Cartesian dualism, a materialist foundation that disassociates the individual from self, other, and nature, and falls short of addressing the mental health, environmental, and cultural challenges facing youth today. To address this limitation, this paper proposes a complementary convergence between deeper learning and the contemplative traditions of Yoga and Vedānta, whose ancient paradigms of self-inquiry, interconnectedness, and well-being offer …
