How To Propagate Interval (And Fuzzy) Uncertainty: Optimism-Pessimism Approach, Vinícius F. Wasques, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical situations, inputs to a data processing algorithm are known with interval uncertainty, and we need to propagate this uncertainty through the algorithm, i.e., estimate the uncertainty of the result of data processing. Traditional interval computation techniques provide guaranteed estimates, but from the practical viewpoint, these bounds are too pessimistic: they take into account highly improbable worst-case situations when all the measurement and estimation errors happen to be strongly correlated. In this paper, we show that a natural idea of having more realistic estimates leads to the use of so-called interactive addition of intervals, techniques that has already …

Incidence And Laplacian Matrices Of Wheel Graphs And Their Inverses, Jerad Ipsen, Sudipta Mallik

Mathematics Faculty Research

It has been an open problem to find the Moore-Penrose inverses of the incidence, Laplacian, and signless Laplacian matrices of families of graphs except trees and unicyclic graphs. Since the inverse formulas for an odd unicyclic graph and an even unicyclic graph are quite different, we consider wheel graphs as they are formed from odd or even cycles. In this article we solve the open problem for wheel graphs. This work has an interesting connection to inverses of circulant matrices.

Faculty Publications

Cleanroom ventilation systems are well-established; however, the advantages and limitations of current practices need to be examined and explained further. This study begins by looking over the history of cleanroom ventilation systems that creates the basis for understanding ventilation rate specifications, terminologies employed in ventilation effectiveness, and recognizing scientific studies that correlate ventilation effectiveness with air change rates. This systematic review includes a comprehensive summary that contains a set of historical data and evidence that may be used to specify ventilation requirements in cleanrooms. Scientific articles are classified in terms of laboratory experiments, simulations/numerical analysis, or hybrid. HVAC designers and …

Lossy Kernelization Of Same-Size Clustering, Sayan Bandyapadhyay, Fedor V. Fomin, Petr A. Golovach, Nidhi Purohit, Kirill Simonov

Computer Science Faculty Publications and Presentations

In this work, we study the k-median clustering problem with an additional equal-size constraint on the clusters from the perspective of parameterized preprocessing. Our main result is the first lossy (2-approximate) polynomial kernel for this problem parameterized by the cost of clustering. We complement this result by establishing lower bounds for the problem that eliminate the existence of an (exact) kernel of polynomial size and a PTAS.

Being And Becoming Global Citizens: Measuring Progress Toward Sdg 4.7. Phase I: Monitoring Teacher And School Readiness To Enact Global Citizenship In The Asia-Pacific Region, Rachel Parker, Jennie Chainey, Payal Goundar, Sarah Richardson, Anna Dabrowski, Amy Berry, Claire Scoular

Global education monitoring

Substantive work has been undertaken to define and frame global citizenship education (GCED). Global citizenship and related terms are included in the curricula and policy statements of many diverse nations around the world (Parker & Fraillon, 2016; APCEIU, 2020b), however, the education sector often struggles to enact and monitor GCED in ways that reflect the changing conditions of students and schools. This study responds to an identified need for enhanced tools and resources for schools and systems to monitor and evaluate GCED, in accordance with United Nations (UN) Sustainable Development Goal (SDG) 4.7. This need is particularly pressing in the …

Long-Term Monitoring Of Clodronate In Equine Hair Using Liquid Chromatography-Tandem Mass Spectrometry, Heather K. Knych, D. S. Mckemie, S. Yim, S. D. Stanley, R. M. Arthur

UK CARES Faculty Publications

Given the potential for long-term inhibition of bone remodeling/healing and detrimental effects to horses in training, bisphosphonates are tightly regulated in horseracing. Hair has proven to be an effective matrix for detection of drug administration to horses and has been particularly effective in detecting drugs for a long period of time post administration. Thus, hair may prove to be a useful matrix for detection of administration of this class of drugs. The objective of the current study was to develop an assay and assess the usefulness of hair as a matrix for long-term detection of clodronate to horses. Seven horses …

Perspective, Invention, And Metatheater In Renaissance Literature, William Roudabush

English Theses and Dissertations

This dissertation challenges the misconception of post-Reformation England as iconophobic. On the contrary, it argues that early modern English poets and playwrights adapt Continental theories and techniques from painting, translating them into their own poetic and dramatic forms. It explores how allusions to contemporary perspectival images serve as governing metaphors and structural devices for the works in which they appear. Particularly in the genre of the Elizabethan epyllion and in works by Shakespeare, it suggests that texts are designed to be read “perspectively,” to borrow Shakespeare’s coinage, so that they are open to ambiguity and multiplicity, and capable of being …

The Synthesis Of Novel Rare Earth Thiosilicates Using The Boron Chalcogen Mixture Method For An Interest In Their Magnetic And Optical Properties, Adam Alexander King

Theses and Dissertations

The chalcogens or the group sixteen elements excluding oxygen, are of interest due to their wide variety of structures and compositions, which gives the potential for a plethora of desired physical properties. This is due to their increased ability to catenate, forming stable chalcogen-chalcogen bonds. When the chalcogens combine with certain main group elements and transition metals they form anionic framework building blocks known as chalcometallates. One such chalcometallate of interest is the thiosilicates, compounds containing Si-S bonds as the anionic frameworks. These compounds are of interest due to their potentials in both their optical and magnetic properties. However, traditional …

Balanced Blended Space: Foundational Human–Ai Dialogues In A Symmetry-Based Mediation Framework, David Smith

Publications and Research

This working paper documents the early development of the Balanced Blended Space (BBS) framework through a series of iterative interactions between a cognitive agent (human researcher) and a computational agent (AI system) conducted in 2023. The work is motivated by the need for a universal theoretical model capable of describing the integration of physical, virtual, and conceptual spaces, particularly in response to increasing fragmentation across contemporary communication systems.

BBS is proposed as a symmetry-based mediation framework in which relationships between domains—such as physical and virtual space, cognition and computation, and multiple sensory modalities—are treated as structurally equivalent and mappable. Central …

Supporting Meaningful Learning Experiences With Button-Operated Robots In Early Childhood Settings, Jacob Hall, David J. Mulder

Faculty Work Comprehensive List

Bringing together recent research on button-operated robots in early childhood settings and developmentally appropriate practices, this chapter details strategies for the integration of robots. Educators are encouraged to design and implement robotics experiences that are intentional, active, constructive, cooperative, and authentic (Howland et al., 2012). To achieve these aims, educators should embed challenges within play-based activities and empower children to set and achieve their own goals. Additionally, educators can support children’s active engagement by selecting a button-operated robot that gives clear feedback and by offering just-in-time support as children address errors in their programs. For constructive learning, educators should prompt …

Interpolation Problems And The Characterization Of The Hilbert Function, Bryant Xie

Mathematical Sciences Undergraduate Honors Theses

In mathematics, it is often useful to approximate the values of functions that are either too awkward and difficult to evaluate or not readily differentiable or integrable. To approximate its values, we attempt to replace such functions with more well-behaving examples such as polynomials or trigonometric functions. Over the algebraically closed field C, a polynomial passing through r distinct points with multiplicities m1, ..., mr on the affine complex line in one variable is determined by its zeros and the vanishing conditions up to its mi − 1 derivative for each point. A natural question would then be to consider …

Variability In Consumption And End Uses Of Water For Residential Users, Camilo J. Bastidas Pacheco, Jeffery S. Horsburg, Attallah A. Nour

Outreach

Research Objective/Summary: In most large urban water systems in the US, the residential sector consumes the majority of total supplied fresh water. In a world plagued with increasing water scarcity and climate change stresses, understanding individual home water end-uses is vital to water management and conservation. We studied the end uses of water in residential homes, both indoor and outdoor to find patterns and variations in consumption over time. Results indicate a need for more efficient water fixtures, particularly toilets, and provide an opportunity to promote conservation behavior.

Polygonal Faults In The Austin Chalk: Invariance Of Scale From Mud Cracks To Polygons With Implications Of Structural, Geomorphic And Isotopic Data On Polygonal Fault Geometry And Origin., Kun Shang

Earth Sciences Theses and Dissertations

The Cretaceous Austin Chalk contains large numbers of fractures and normal faults whose orientations have been attributed to either regional stresses (e.g., the Balcones fault trend) or, by analogy with the mudrocks, to polygonal faulting resulting from compaction. In this study, we present geomorphic data, field study, and stable isotope data to support that the majority of these faults in North Texas are polygonal. Field-measured fault orientations suggest randomly distributed fault strikes, indicating a polygonal fault structure. Using geomorphologic data (topographic and DEM data) on stream orientations suggests that the polygonal fault patterns are best reflected in the headwater (1st …

Predicting Corrosion Damage In The Human Body Using Artificial Intelligence: In Vitro Progress And Future Applications Applications, Michael A. Kurtz, Ruoyu Yang, Mohan S. R. Elapolu, Audrey C. Wessinger, William Nelson, Kazzandra Alaniz, Rahul Rai, Jeremy L. Gilbert

Publications

Artificial intelligence (AI) is used in the clinic to improve patient care. While the successes illustrate the impact AI can have, few studies have led to improved clinical outcomes. A gap in translational studies, beginning at the basic science level, exists. In this review, we focus on how AI models implemented in non-orthopedic fields of corrosion science may apply to the study of orthopedic alloys. We first define and introduce fundamental AI concepts and models, as well as physiologically relevant corrosion damage modes. We then systematically review the corrosion/AI literature. Finally, we identify several AI models that may be Preprint …

Hypo-Osmotic Stress And Pore-Forming Toxins Adjust The Lipid Order In Sheep Red Blood Cell Membranes, Rose Whiting, Sevio Stanton, Maryna Kucheriava, Aviana R. Smith, Matt Pitts, Daniel Robertson, Jacob Kammer, Zhiyu Li, Daniel Fologea

Physics Faculty Publications and Presentations

Lipid ordering in cell membranes has been increasingly recognized as an important factor in establishing and regulating a large variety of biological functions. Multiple investigations into lipid organization focused on assessing ordering from temperature-induced phase transitions, which are often well outside the physiological range. However, particular stresses elicited by environmental factors, such as hypo-osmotic stress or protein insertion into membranes, with respect to changes in lipid status and ordering at constant temperature are insufficiently described. To fill these gaps in our knowledge, we exploited the well-established ability of environmentally sensitive membrane probes to detect intramembrane changes at the molecular level. …

New Secondary Mathematics Teachers’ Perceptions Of Their Experience In A New Teacher Induction Program In A School District In Tennessee, Ashley Miller

Ed.D. Dissertations

New teachers felt unprepared as they entered their first year of teaching and were leaving the teaching field at a high rate every school year. Tennessee, like many other states, had a critical shortage of secondary mathematics teachers. Secondary mathematics has been considered a high-needs subject area. New teacher induction programs were developed to help support new teachers and aid in their retention; however, the state of Tennessee did not have a requirement for mentoring or induction support for new teachers. The purpose of this qualitative case study was to explore new secondary mathematics teachers’ perceptions of their experiences in …

The Role Of Faculty In Durable Skills Development In Higher Education, James Hutson, Mark Valenzuela, Shannon Wright, Elizabeth Melick

Faculty Scholarship

Although Emsi and other market researchers have found that employers desire durable skills (formerly known as “soft skills”) in new hires, there have been few studies dedicated to identifying how faculty perceptions of skill development differ in degree and by area, and how that might impact how such skills are embedded in classroom instruction. This study proposes to investigate the perceptions of faculty from different academic backgrounds and how their disciplines and experiences may contribute to their perceived role in curricular, cocurricular or extracurricular offerings that support durable skill development. Results from the study demonstrate the differing perspectives and expectations …
