Show moreThe primary objective of this dissertation is to gain insight into geomagnetic storm effects at mid-latitudes induced by solar activity. Geomagnetic storms affect our everyday lives because they give rise to transient signal loss, data transmission errors, negatively impacting users of satellite navigation systems. The Nighttime Localized Ionospheric Enhancement (NILE) is a localized plasma enhancement that because it is not well understood, drives the design of satellite-based augmentationsystems. To better secure operation of technological infrastructure, it is essential to build a comprehensive understanding of the atmospheric drivers, especially during solar active periods. Instrument measurements and climate models serve as valuable tools in obtaining information regarding the occurrence of space weather events; nonetheless, both sources exhibit quantitative and qualitative limitations. Data assimilation, an evolving technique, integrates measurements and model information to optimize the state estimations. This dissertation presents developments in a data assimilation algorithm known as Estimating Model Parameters from Ionospheric Reverse Engineering (EMPIRE), and its applications in investigating the atmospheric behaviors under varying solar conditions. EMPIRE is a data assimilation algorithm specifically designed for upper atmospheric driver estimation of neutral wind and ion drifts at user-defined spatial and temporal scales. The EMPIRE application in this work aims to contribute to a more comprehensive understanding of the effects of the NILE. EMPIRE utilizes the Kalman filter to optimize state calculations primarily based on electron density rates, provided by other data assimilation algorithms. Earlier runs of the algorithm used pre-defined values for the background state covariance cross time. To address model limitations under changing geomagnetic conditions, the algorithm is enhanced by concurrently updating the background state covariance during assimilation processes. Additionally, representation error is incor- porated as a component of the observation error, and error analysis is performed through a synthetic-data study. Previously, EMPIRE fused Fabry-Perot Interferometer (FPI) neutral wind measurements, demonstrating increased agreement with validation neutral wind data. In this work, this approach is extended to augment Coherent Scatter Radar (CSR) ion drift measurements from Super Dual Auroral Radar Network (SuperDARN), providing additional insights into EMPIRE’s estimated field-perpendicular ion motion. For an in-depth exploration of storm-related NILE, both EMPIRE and another data assimilation method, the Whole Atmosphere Community Climate Model with thermosphere and ionosphere eXtension coupled with Data Assimilation Research Testbed (WACCM-X + DART), is implemented for a storm event to test the proposed NILE driving mechanism. Furthermore, this dissertation introduces a Kalman smoother technique into the EMPIRE to enhance its ability to assess past storm events, and to explore the potential for algorithm improvements.

Title: Impact of Social Constructs on Stereotype Threat and Working Memory in Older Adults

Show moreIntroduction/Background: When individuals underperform in a task or situation due to fear of confirming a negative stereotype about themselves or a group they identify with, this psychological phenomenon is called “stereotype threat.”Objectives: This study focuses on older adults, who are often unfairly stereotyped as cognitively impaired. Declines in working memory (WM) can disrupt efficient information processing and both short- and long-term memory consolidation. Additionally, stigma consciousness and worry about developing dementia might influence this relationship, as these factors are particularly relevant to older adults. Methods: 103 older adults (Mage = 71.01 years old) recruited through ResearchMatch were screened via the telephone version of the Montreal Cognitive Assessment (T-MoCA), given two cognitive tests (WAIS-IV Digit Span Test and Arithmetic), Stigma Consciousness Questionnaire, Fear of Alzheimer’s Disease Scale, and a demographics questionnaire. Analysis completed through structural equational modeling and path analysis. Results: Our analysis did not reveal any significant findings in our path analysis or bivariate correlations. Thus, our hypotheses were not supported. Discussion: Despite the lack of findings, conducting a ST study by phone is an innovative approach that could expand research on ST outside traditional lab settings, where participants might otherwise feel less threatened and what this means for clinicians.

Show moreThe demand for timely information updates is growing with the proliferation of real-time applications such as remote monitoring, autonomous vehicles, and Internet of Things (IoT) networks. The age of Information (AoI), a critical performance metric, quantifies the freshness of received information. This dissertation addresses the challenge of minimizing AoI in practical wireless networks employing carrier sense multiple access (CSMA). We propose a comprehensive framework combining analytical modeling and deep learning techniques to optimize AoI under diverse network conditions.First, we introduce a deep learning-facilitated framework that enables a tagged node to adaptively adjust its update rate based on local observations and background traffic, minimizing its AoI. Extensive simulations in IEEE 802.11 networks validate this framework’s effectiveness. We then extend the framework to IEEE 802.15.4 networks, incorporating key protocol characteristics such as clear channel assessments and retransmissions. Simulation results demonstrate its generalization capability and significant AoI improvement.Next, we develop a novel stochastic hybrid systems (SHS)-based analytical model to evaluate AoI in finite-buffer CSMA networks. By incorporating collision probabilities and leveraging deep learning to handle heterogeneous background traffic, this model achieves accurate AoI analysis. Numerical results from ns-3 simulations confirm its robustness and scalability across various scenarios. Furthermore, we explore the interplay between AoI and other metrics, introducing ``throughput weighted age of information (TwAoI)" to evaluate the joint performance of information freshness and channel utilization, and investigating the trade-off between information freshness and sampling cost.This research bridges theoretical insights and practical implementation, providing a suite of tools for AoI optimization in CSMA networks. The findings serve as a guideline for system designers and network administrators aiming to support real-time applications in dynamic and distributed wireless environments.

Show moreBy refashioning the design and programmatic use of an offshore oil rig into a luxury hotel for ecotourists, a new age of responsible travel may emerge. By twisting the symbol of oil dependency into an ecologically preserved, environmentally accountable and revenue-producing prototype, the ideals of reuse, energy and environment can be viewed through a new lens. This design creates interesting and innovative living spaces and environments aided by sustainable integrations to create a “living machine” that establishes connections between all building systems as well as inhabitant inputs and outputs resulting in an energy independent habitat.
