Consistency-Based Computing Of Fuzzy Eigenvalues And Fuzzy Eigenvectors: Method And Application, Kamala. R. Aliyeva Prof., Nihad Mehdiyev, Shamil Mehdi
Consistency-Based Computing Of Fuzzy Eigenvalues And Fuzzy Eigenvectors: Method And Application, Kamala. R. Aliyeva Prof., Nihad Mehdiyev, Shamil Mehdi
Chemical Technology, Control and Management
The computation of eigenvalues and eigenvectors under uncertainty is a fundamental problem in fuzzy linear algebra and decision analysis. When matrix elements are represented by fuzzy numbers, classical spectral methods cannot be directly applied due to nonlinearity, ambiguity in ordering, and the propagation of uncertainty. Moreover, in many practical applications, particularly those involving pairwise comparison matrices, the reliability of eigenvalue-based results strongly depends on the consistency of the underlying data. This paper proposes a consistency-based framework for computing fuzzy eigenvalues and fuzzy eigenvectors that explicitly integrates consistency analysis into the spectral derivation process. The proposed method preserves the fuzzy structure …

Immersive Virtual Reality or VR/VX stands poised to revolutionize healthcare education through interactive learning modules, overcoming current deficiencies in existing methodologies for instruction. This research compared the effectiveness of VR/VX-based training to traditional CT scanner operator training using a within-subjects design, involving 30 subjects, and concluded the effectiveness of using VR/VX in enhancing knowledge retention, task accomplishment, and engagement, and proved it by showing significant enhancement in immediate knowledge acquisition scores (Δ = 8.87, t(29) = 6.71, p < .0001), relative to delayed knowledge retention scores (Δ = 11.03, t(29) = 6.85, p < .0001), procedural achievement scores (Δ = 5.40, t(29) = 4.45, p = .0001), reduced overall task completion time using VR/VX for increased speed of execution (t(29) = 10.74, p < .0001), as well as reduced task errors for lower error rates using VR/VX in comparison to existing methodologies, as testified by the results, t(29) = 8.14, p < .0001, respectively, while showing no significant difference in usability, although assessed superior in terms of engagement and relative usefulness by the involved subjects.
Vulnerability Of Bass Populations To Our Changing Climate In The Mississippi River, Cameron Schreifels
Vulnerability Of Bass Populations To Our Changing Climate In The Mississippi River, Cameron Schreifels
Celebrating Scholarship and Creativity Day (2018-)
Climate change is altering habitats and damaging bass populations throughout the Mississippi. The main factors of climate change affecting bass are shifts in water quality and significant weather events, which have increased bass vulnerability. With rising temperatures and eutrophication changing the way these bass hunt for their prey, it has made it easier for other non-native species to encroach on their habitat, which has led to bass further encroaching on other species due to climate change. Given their economic importance and cultural significance, better management practices are needed to find new ways to protect them and ensure they remain a …
Inhibition Of The Pi3k/Akt/Mtor Pathway In Non-Small Cell Lung Cancer, Gretchen Gunderzik
Inhibition Of The Pi3k/Akt/Mtor Pathway In Non-Small Cell Lung Cancer, Gretchen Gunderzik
Celebrating Scholarship and Creativity Day (2018-)
The phosphatidylinositol 3-Kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamycin (mTOR) signaling pathway is a cell survival pathway that is commonly unregulated in non-small cell lung cancer (NSCLC). Current inhibitors of this pathway often face the challenge of inherent and developed resistance. There is the need to further develop a targeted treatment therapy focused on inhibition of this signaling pathway. This could synergistically enhance commonly used cancer therapies such as chemotherapy, which NSCLC patients often develop resistance to. Due to the complexity of the pathway, dual inhibition is an intriguing avenue of research as it helps to mitigate resistance from …
A Boron Umbrella: Enhancing The Hydrolytic Stability Of Boronic Ester Based Covalent Adaptable Networks Toward The Development Of Recyclable Thermoset Polymers, Twila Lefeber
Celebrating Scholarship and Creativity Day (2018-)
The accumulation of non-recyclable thermoset plastic waste demonstrates a need for high- performance materials that bridge the gap between the reprocessability of thermoplastics and the durability required for industrial materials. Previous research has produced high-strength and recyclable hydrogenated nitrile butadiene rubber (HNBR) materials using boronic ester crosslinks, but the susceptibility of the Lewis acidic boron atom makes it vulnerable to hydrolysis which limits longevity in humid or aqueous environments. The proposed research aims to target covalent adaptable networks (CANs) based on the boronic ester interaction, and their instability in water. Three structurally modified crosslinkers are proposed to incorporate into a …
Aquatic Invasive Species Control: Minnesota’S Herbicide Problem, Adam Novak
Aquatic Invasive Species Control: Minnesota’S Herbicide Problem, Adam Novak
Celebrating Scholarship and Creativity Day (2018-)
Minnesota lakes have an invasive species problem: invasives are outcompeting our native plants and causing ecological degradation. Herbicides are used in Minnesota to help alleviate the stress that invasive plants put on the ecosystem, but continued use of herbicides has its own environmental downside. An analysis of five common aquatic herbicides including, diquat, endothall, 2,4-D, fluridone, and copper-based solutions was completed to find specific ecological downsides. Sediment degradation, effects on various fish life stages, zooplankton, and other non-target organisms were analyzed. This study offers alternative managements strategies and presents a decision tree to help lake associations manage invasive plants.

Tour Geography Of Bad Bunny Compared With Hispanic Demographics In The United States, Arabella Fuzak
Celebrating Scholarship and Creativity Day (2018-)
This project looks at how the distribution of Bad Bunny’s tour locations has changed over time and how they relate to concentrations of the Hispanic/Spanish-speaking population in the United States. The first map visualizes the tour stops (across all of the tours Bad Bunny has made in the United States, which were found by social media posts), along with how many shows he has done in each state. The second map looks at the percent of residents per county in the United States who are Hispanic. The third map looks at the percent of residents per county in the United …
An Analysis Of A Family Of Root Finding Methods, Arabella Fuzak
An Analysis Of A Family Of Root Finding Methods, Arabella Fuzak
Celebrating Scholarship and Creativity Day (2018-)
This thesis analyzes the behavior of a family of iterative root-finding methods, the Hansen-Patrick Family, which has a parameter, alpha, to create methods such as Newton’s methods, Halley’s method, and Euler’s method. By varying the parameter alpha, with both real and complex values, this project examines how the parameter can change convergence, divergence, and stability for different functions. This is shown by basin maps and Mandelbrot-like sets to visualize this behavior and classify points based on whether they converge to a root, diverge to infinity, or remain bounded without converging.

Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith
Honors Theses
Antibiotic resistance is a growing threat to public health. Due to the overuse of antibiotics in agriculture, the overprescription of antibiotics, and the misuse of antibiotics by patients, antibiotic resistance is spreading at an alarming rate. As antibiotic resistance spreads, the antibiotics we depend on to treat common infections become ineffective. Therefore, it is imperative to develop novel treatments for infections that do not increase the prevalence of antibiotic resistance. One treatment being explored is the use of synthetic polymers with antibacterial properties. Synthetic polymers are advantageous because they can be synthesized from widely available precursors and their structure is …
Redefining Certainty: Non-Euclidean Geometry And Theology Transformation Throughout The Intellectual Unrest Of The Early 1800s, Luke Bensinger
Redefining Certainty: Non-Euclidean Geometry And Theology Transformation Throughout The Intellectual Unrest Of The Early 1800s, Luke Bensinger
Honors Theses
To bridge the gap between mathematics and theology, it is necessary to explore their intersection and challenge the notion that these fields are incompatible. This study focuses on the 19th century, a period when non-Euclidean geometries emerged and disrupted mathematical certainty, while Protestant theologians such as Barton W. Stone and Alexander Campbell grappled with Calvinism and shifting theological perspectives. By analyzing mathematicians studying geometry, such as Gauss, Lobachevsky, and Riemann, this research examines how both disciplines balance change with enduring truths.
