Climate Change-Related Effects On Carbon Emissions And Net Ammonification Across Lowland To Upland Soils From A High-Latitude Coastal Ecosystem, Jenna M. Ross, Karen H. Beard, Katharine C. Kelsey, Matteo Petit Bon, A. Joshua Leffler Apr 2026

Climate Change-Related Effects On Carbon Emissions And Net Ammonification Across Lowland To Upland Soils From A High-Latitude Coastal Ecosystem, Jenna M. Ross, Karen H. Beard, Katharine C. Kelsey, Matteo Petit Bon, A. Joshua Leffler

Wildland Resources Faculty Publications

Warming, sea-level rise, and changing herbivory patterns are affecting ecosystem processes in northern coastal soils, including carbon and nitrogen cycling, although their combined effects are poorly understood. We studied the impact of these changes in a full-factorial microcosm experiment using four distinct soil types from the Yukon-Kuskokwim Delta of western Alaska. Soil was collected from three coastal wetlands, which differ in flooding frequency and use by migratory geese, and one rarely-flooded upland tundra used by geese in late summer. Microcosms containing these soils were incubated for 16 weeks at 10°C or 18°C, with or without three short-term floods, and with …


Regular Synthesis Algorithms Of Control Devices In Nonlinear Control Systems, Husan Zakirovich Igamberdiyev, Iskandar Yusupovich Abdurakhmanov, Uktam Farkhodovich Mamirov Apr 2026

Regular Synthesis Algorithms Of Control Devices In Nonlinear Control Systems, Husan Zakirovich Igamberdiyev, Iskandar Yusupovich Abdurakhmanov, Uktam Farkhodovich Mamirov

Chemical Technology, Control and Management

This paper examines the development of regularized algorithms for synthesizing control devices in control systems for polynomial objects, described by multidimensional Volterra functional series. The synthesis problem is solved using a two-stage procedure. In the first stage, the optimization problem is initially solved for an open-loop system. The second stage involves determining the parameters of the control device, i.e., its impulse response functions, by using the relationship between the characteristics of the open-loop and closed-loop systems. Regular algorithms are presented for finding the impulse response functions of the control device based on methods for regularizing the solution of operator equations …


Using Ali-4 Z-Implication In Controller Design, Shamil Azer Ahmadov Apr 2026

Using Ali-4 Z-Implication In Controller Design, Shamil Azer Ahmadov

Chemical Technology, Control and Management

One of the widely used theories in the information processing is Professor Zadeh's fuzzy logic theory. Fuzzy implications form the basis of this theory. When processing information using fuzzy implication, the chosen judgment method and the type of implication affect the result. Referring to the review of the relevant literature on fuzzy implications, it can be noted that there are still unresolved problems and issues. For example, fuzzy implications cannot be used in processing imperfect information or information based on probabilistic and fuzzy uncertainty. Existing fuzzy implications face limitations in practical applications. Fuzzy implications only take into account inaccuracy, but …


Game Bidding Strategy For Electric Thermal Gas Coupled Virtual Power Plants Participating In Main And Auxiliary Joint Markets, Chunyan Zhang, Zhenlan Dou, Ng Jihang Zha, Lingling Wang, Chuanwen Jiang Apr 2026

Game Bidding Strategy For Electric Thermal Gas Coupled Virtual Power Plants Participating In Main And Auxiliary Joint Markets, Chunyan Zhang, Zhenlan Dou, Ng Jihang Zha, Lingling Wang, Chuanwen Jiang

Journal of Electric Power Science and Technology

As integrated energy systems develop, multi-energy coupled virtual power plants have become an effective way to manage integrated energy systems. However, due to their numerous internal energy types, complex coupling relationships, and inability to obtain competitor information when participating in the market, it is difficult to solve their bidding strategies by adopting traditional mathematical methods. A game bidding strategy for electric thermal gas coupled virtual power plants participating in main and auxiliary joint markets based on constraint-aware multi-agent reinforcement learning is proposed. Firstly, a mathematical model of a multi-energy coupled virtual power plant is built and the energy flow relationship …

Creating A Unique Hemoglobin-Based Oxygen Carrier, Clayton Fuller Apr 2026

Creating A Unique Hemoglobin-Based Oxygen Carrier, Clayton Fuller

Celebrating Scholarship and Creativity Day (2018-)

The purpose of this thesis is to explain the current state of alternative oxygen carriers and propose a new hemoglobin-based oxygen carrier (HBOC) as a blood substitute/ blood therapeutic. Blood donation has drawbacks: risk of spread of infection, short storage time, and blood typing, and the current shortage. There are several possible modifications for hemoglobin to create a carrier (HBOC) which address specific issues related to allowing free hemoglobin to exist extra cellularly. One issue to address is vasoconstriction caused by nitric oxide scavenging, which has been solved by increasing the molecular weight of the HBOC via (co)polymerization, or by …

Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith Apr 2026

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 …


Human Dignity In The Foundational Political Documents Of The United States, Kalista Roades Apr 2026

Human Dignity In The Foundational Political Documents Of The United States, Kalista Roades

Honors Theses

Human dignity is integral to modern discussions of human rights and liberties, but this connection can be found stretching back through history to the early developments of human rights. This paper begins with modern philosophical definitions of human dignity, especially from Rosen and Kateb. Rosen discusses four “strands” of dignity- Intrinsic Dignity, Status Dignity, Manner Dignity, and Respect Dignity. This paper then uses that framework to find human dignity implicit within the founding documents of the United States including the Declaration of Independence, the Constitution, and the Bill of Rights, as well as “Common Sense” and the Magna Carta to …


Network Analysis: An Application Of Graph Theory In Biology, Kiana Dunbar Apr 2026

Network Analysis: An Application Of Graph Theory In Biology, Kiana Dunbar

Honors Theses

Graphs are simple, visual representations of entities as nodes connected by edges. They are used to convey relationships within a system. Networks are comprised of interrelated entities that are not easily separable, producing complex, structured data. These can be seen in social groups, highway systems, and even in biological systems. This paper surveys concepts in graph theory for application to the analysis of network data to understand disease. The features of graphs provide a useful framework for thinking about relationships between different genes or proteins. The structure of graphs is also compatible with a variety of machine learning tools. Especially …

Monitoring large-scale afforestation projects in arid and semi-arid environments requires accurate, high-resolution, and repeatable methods to assess tree survival and growth. In this study, we integrated unmanned aerial vehicle (UAV) multispectral imaging with an advanced object detection framework to evaluate vegetation establishment in the Shuayb Al-Budai afforestation site, part of the Imam Turki bin Abdullah Royal Natural Reserve, Kingdom of Saudi Arabia (KSA). Multispectral datasets were acquired using a MicaSense Altum-PT sensor and processed through a masked Region-based Convolutional Neural Network (RCNN) with two backbone architectures: ResNet-101 and VGG19-BN. The Mask R-CNN–ResNet-101 model achieved superior performance, with an overall accuracy …
