A Survey Of Mission Opportunities To Trans-Neptunian Objects - Part 7: Utilization Of A Delta-Vega Maneuver, Colter W. Russell, Christopher J. Busic, Andrew M. Farris, Jeongmin A. You, Raj V. Patel, James E. Lyne

Haslam Scholars Projects

Trans-Neptunian Objects have gained interest in lieu of the success of the New Horizons mission. This paper seeks to further the design possibilities for such missions by offering sixteen trajectories to TNO’s by incorporating a Delta-VEGA maneuver, which allows for increased payload mass. These trajectories were simulated using Spaceflight Solution’s Mission Analysis Environment software, which allowed for constraining of mission parameters for optimization. The trajectories were made to have a C3 below 40 km²/s², minimized transit time, and minimized ΔV. Results are visualized in Figures 3-6 as well as Table 1, which contain all relevant descriptive …

Connecting Islamic Technology And The History Of Robotics In Wikidata Via Wikidatabot, Anchalee Panigabutra-Roberts

UT Libraries Faculty: Other Publications and Presentations

My current study is on the connection between the history of robotics and Islamic technology. I focused on early Muslim inventors, such as al-Jazari, from Artuqid Dynasty of Jazira in Mesopotamia (modern day Iraq, Syria and Turkey) who is considered to be the father of robotics. He wrote the Book of Knowledge of Ingenious Mechanical Devices, the manuscript treaty published after his passing in 1206, translated by Donald R. Hill, a British engineer and scholar on Islamic technology, in 1974. The manuscript in Arabic (MS. Greaves 27) is archived at the Bodleian Library, University of Oxford, United Kingdom. In …

Identification of Emergent Collaborative Behaviors in Multi-Agent Systems

Bryson Howell

Multi-Agent Reinforcement Learning (MARL) has been used to allow groups of autonomous agents to perform complex cooperative tasks. When MARL methods such as the Multi-Agent Deep Deterministic Policy Gradient (MADDPG) algorithm [1] are used to train teams of agents in cooperative tasks, it has been observed that the actions of individual agents are significantly influenced by the actions of their teammates [2]. Additionally, prior work has shown that teams of agents trained independently of one another under identical conditions display a variety of behaviors [3]. Since these teams have been …

Development Of A Temperature Measurement Camera Using Cost Effective Hardware, Benjamin F. Thieme, Jesse Wilson

Haslam Scholars Projects

The recent outbreak of the COVID-19 pandemic has caused lock downs around the globe, forcing many schools and businesses to temporarily close. For them to reopen safely, it is imperative to identify cases quickly so that individuals can be quarantined before the virus spreads to more people. An alternative to testing is to screen individuals for high temperatures that would indicate fevers. With the risk of contagion that occurs during close contact between humans, traditional thermometers may be unsuitable. Thus, the purpose of this design project is to design, construct, and test a temperature measurement system using a thermal camera …

Approximation Of The Time Rate Of Consolidation For Hydraulically Placed Fine Coal Refuse Using A Variable Coefficient Of Consolidation Method, Cyrus Jedari, Eric Drumm, Angelica Palomino

Faculty Publications and Other Works -- Civil & Environmental Engineering

Terzaghi’s consolidation theory assumes strain in soil due to applied overburden pressure is small, and permeability and thus the coefficient of consolidation (C_v) remain constant during consolidation. Although valid for soft soil consolidation, the C_v for hydraulically placed slurry materials with low solids content may change significantly during the consolidation process as the material transitions from a slurry to a solid. In this study, a spatial and temporal variable C_v was used to predict the time rate of consolidation of fine coal refuse placed in an impoundment as a slurry. The results suggest the variable …
