Faculty Research 2023

The Retinoid-related orphan receptor beta (RORβ) gene encodes a developmental transcription factor and has 2 predominant isoforms created through alternative first exon usage; one specific to the retina and another present more broadly in the central nervous system, particularly regions involved in sensory processing. RORβ belongs to the nuclear receptor family and plays important roles in cell fate specification in the retina and cortical layer formation. In mice, loss of RORβ causes disorganized retina layers, postnatal degeneration, and production of immature cone photoreceptors. Hyperflexion or "high-stepping" of rear limbs caused by reduced presynaptic inhibition by Rorb-expressing inhibitory interneurons of the …

End To End Routing Algorithms In Arbitrary Networks, Nada Alzaben

Computer Science and Engineering Theses and Dissertations

The End to End Routing Problem in computer communication networks is the problem of scheduling fixed routes through the network over time. All the packets in a single communication flow follow an assigned route and all flows are routed such that some function of the flows is optimized. A flow is a sequence of packets that are released by some source node and sent over the communication network to a destination node. Multiple objective functions may be used to evaluate the performance of the network. Common objective functions include minimize the mean wait time, minimize the total wait time, minimize …

Bivariate Copula Regression Models For Semi-Competing Risks, Yinghui Wei, M Wojtys, Lexy Sorrell, Peter Rowe

School of Engineering, Computing and Mathematics

Time-to-event semi-competing risk endpoints may be correlated when both events occur on the same individual. These events and the association between them may also be influenced by individual characteristics. In this article, we propose copula survival models to estimate hazard ratios of covariates on the non-terminal and terminal events, along with the effects of covariates on the association between the two events. We use the Normal, Clayton, Frank and Gumbel copulas to provide a variety of association structures between the non-terminal and terminal events. We apply the proposed methods to model semi-competing risks of graft failure and death for kidney …

Influence Of Ultrasound Machine Settings On Quantitative Measures Derived From Spatial Frequency Analysis Of Muscle Tissue, Scott K. Crawford, Stephanie A. Kliethermes, Bryan C. Heiderscheit, Greg Bashford

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background Ultrasound is a powerful tool for diagnostic purposes and provides insight into both normal and pathologic tissue structure. Spatial frequency analysis (SFA) methods characterize musculoskeletal tissue organization from ultrasound images. Both sonographers in clinical imaging and researchers may alter a minimized range of ultrasound settings to optimize image quality, and it is important to know how these small adjustments of these settings affect SFA parameters. The purpose of this study was to investigate the effects of making small adjustments in a typical default ultrasound machine setting on extracted spatial frequency parameters (peak spatial frequency radius (PSFR), Mmax, Mmax%, and …

Final Report - Augmenting Bridge Inspection With Augmented Reality And Haptics Based Aerial Manipulation, Paul Oh, Blake Hament, Dongbin Kim

Project AS-7

Insight and leverage from prior project identified the need for haptics; the inspector’s sense of touch is often used in bridge assessment. Envisioned is the augmentation of bridge personnel by providing a haptics-based aerial manipulator. Such a manipulator would reduce needs to ascend elevated structures like under bridge decks and cabling. There is recent work that uses haptics in aerial manipulation. But these center on autonomous multi-drone flight formation for aerial shows or cooperative object delivery and are relatively straight-forward. The sense of touch is used to provide spatial distance between drones. By contrast, this proposal’s novelty and merit are …

Assessing The Impact Of Daily Life Events On Depression Symptomatology And The Neural Correlates Of State & Trait Depression Within Resting-State Networks As Deduced By Probabilistic Functional Modes, Rosie Dutt

McKelvey School of Engineering Graduate Student Theses & Dissertations

In our everyday lives, we experience several life events that are either positive in nature (uplifting events) or irritating in nature (hassling events). Independently, these events may not impact an individual’s mood, but together they may accumulate to do so. As such, one would hypothesize that a greater number of hassles experienced would lead to a higher depression level, whilst a greater number of uplifts experienced would lead to a lower depression level. The first Aim of this thesis is to investigate the association between cumulative life events and depression using a linear regression model. The findings revealed that life …

Optimization Of Propulsion Systems With Real-Time Precise Orbit Determination Technology To Enable Proximity Operations And Advanced Mission Capabilities, Sakari Teerikoski, Javier Tegedor, James Bartle, John Lawrence, Frank Tobin

Small Satellite Conference

Precise orbit determination technologies are an increasingly important enabler for the validation of critical in-space satellite propulsion systems. Advanced maneuvers require precise knowledge of impulse to optimize operations related to rendezvous, docking, in-orbit refueling, debris removal, formation flying and optical intersatellite-links optimization. These applications can benefit greatly from enhanced knowledge of the precise position of the satellite performing the work, and the precise position of the target. Thruster-intensive missions benefit from this ability to optimize thruster use and calculate and optimize actual fuel use.

The authors have combined these technologies to offer a precision 6DOF cold-gas propulsion solution with simultaneous, …

Novel Ground Communication For Geo Servicing Missions, Trevor Barth, Dan Mckee

Small Satellite Conference

As geostationary orbit (GEO) rendezvous proximity operations (RPO) missions are being launched as a means to provide life-extension services to active GEO satellites, new novel approaches to ground communication architecture have potential to simplify servicer design, reduce RF interference, and reduce overall mission operation costs. One such approach discussed here involves the servicer vehicle utilizing the client vehicle's active antenna and data stream during combined-stack operations versus maintaining a distinct communication stream with a separate ground station. The proposed method to accomplish this is to provide a physical umbilical connection during docking operations, allowing the servicer vehicle to provide power …
