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 …

Enhancing Long-Term Outcomes: Implementing Community Engaged Research To Augment Substance Use Disorder Treatment, Kevin M. Quinn

Masters Theses

The Universal Evaluation Tool is an intuitive self-assessment instrument to enhance long-term treatment outcomes for Guiding Light’s residential addiction rehabilitation program. Designed as a versatile method for collecting primary data, the Universal Evaluation Tool can be administered to clients at any point during the recovery program (i.e., intake to discharge). The data collected from the survey can be used as a framework to guide treatment decisions, develop personalized care plans, offer insight into a client’s progress, and collect baseline data (e.g., sociodemographic characteristics) on a treatment population for use in grant applications.

A pilot study to generate preliminary data was …

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 …

A Descriptive Study Of Covid-Era Movers To The Northern Forest Region: "The Perfect Balance Of Things...A Choice Based On Lifestyle, Community, And Values", Jess Carson, Sarah Boege, Libby Schwaner

Carsey Publications

The Northern Forest—a 34-county swath of northern Maine, New Hampshire, Vermont, and New York—saw an increase in domestic migration during the pandemic, with 85 percent of the region’s counties experiencing domestic in-migration gains between 2020 and 2021, compared with 63 percent of counties in the rest of the United States. Who moved to the Northern Forest region, and why? Do they intend to stay? And what does that mean for those who already lived there?

In this research brief, authors Jess Carson, Sarah Boege, and Libby Schwaner share findings from interviews with 16 such movers (and six regional real estate …

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 …

Implementation Of A Microthruster Using Pcbmems, José M. Quero, Gonzalo Quero

Small Satellite Conference

This paper describes the implementation of microthrusters using PCBMEMS technology. PCBMEMS is the engineering of MEMS devices based on standard printed circuit board (PCB) technology. The reduced thickness of the copper layers together with the high resolution of the features on a PCB allow the implementation of micrometer-sized devices. A solid fuel microthruster including a tank, detonator and throat has been designed, simulated, manufactured, and tested using this PCBMEMS technology.

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, …

Development Of On-Ground Hardware In Loop Simulation Facility For Space Robotics, Roshan Sah, Raunak Srivastava, Kaushik Das

Small Satellite Conference

Over a couple of decades, space junk has increased rapidly, which has caused significant threats to the LEO operation satellites. A mitigating measure should be taken to protect the LEO space environment. An Active Debris Removal (ADR) concept continuously evolves for space junk removal. One of the ADR methods is Space Robotics, whose function is to chase, capture and de-orbit the space junk. This paper presents the development of an on-ground space robotics facility in the TCS Research for on-orbit refueling and debris capture experiments. A Hardware-in-Loop Simulation (HILS) system will be used for integrated system development, testing, and demonstration. …

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 …
