Eisenhower, Kennedy, And America's Covert Military Operations In Laos, Russell Stevenson
Eisenhower, Kennedy, And America's Covert Military Operations In Laos, Russell Stevenson
The Thetean: A Student Journal for Scholarly Historical Writing
Summer 1963: Roger Hilsman's plane pierced the clouds to reveal the Plaines des Jarres, a flat area strewn with the remains of age-old rock jars. The plains below showed signs of the batterings of war: slit trenches, bunkers, and a network of roads. The weather was dry and arid, and the terrain resembled a ghost town in the American West more than the "land of a million elephants"-an allusion to the tremendous war machine of a medieval Lao king.
A Historiographical Look At The New Soviet Woman, Liberty Sproat
A Historiographical Look At The New Soviet Woman, Liberty Sproat
The Thetean: A Student Journal for Scholarly Historical Writing
Prior to 1917, the character of the ideal woman throughout Russian history was that of wife and mother. This cultural image for women had been upheld by centuries of legislation and tradition. During and immediately after the Bolshevik Revolution, though, the relegation of women to the home began to be considered bourgeois. Consequently, from the revolutionary era to the rise of Stalinism, the Soviets sought to drastically transform gender roles in Russia. Establishing equality between economic classes, the Bolsheviks believed, would likewise establish equality between genders. Thus, they began to promote a new image of Soviet womanhood. The New Soviet …

Digitally Beamformed 2d Scanning Phased Array Radar For Networked Unmanned Air Vehicle Detection And Tracking, Carson Reed Brown
Digitally Beamformed 2d Scanning Phased Array Radar For Networked Unmanned Air Vehicle Detection And Tracking, Carson Reed Brown
Theses and Dissertations
Radar systems vary significantly in size, weight, power, and cost (SWaP-C) characteristics with many high SWaP-C models being inaccessible to consumers. Recognizing this, we have engineered an effective but low SWaP-C networked radar system tailored for detecting and tracking unmanned air vehicle (UAV) traffic. Using field-programmable gate arrays (FPGAs), and custom-designed printed circuit boards (PCBs), our system achieves remarkable efficiency without compromising performance. We use patch antennas for our transmitter and in our 4x4 receiver array. With our low SWaP-C system we have successfully concluded outdoor range testing, detecting corner reflector targets at a remarkable 10dB above our noise floor …
Dna-Templated Nanofabrication Of Metal-Semiconductor Heterojunctions And Their Electrical Characterization, Chao Pang
Theses and Dissertations
Bottom-up nanofabrication, although still in its early stages with formidable challenges, is considered a potential alternative method to address the limitations of traditional top-down techniques by offering benefits including process simplification, cost reduction, and environmental friendliness. DNA-templated nanofabrication, one of the most powerful bottom-up methods, presents an innovative way to create advanced nanoelectronics. In this approach, nanomaterials with specific electronic, photonic, or other functions are precisely and programmably positioned on DNA nanostructures from a disordered collection of smaller parts. These self-assembled structures offer significant potential for improving many fields such as biosensing, drug delivery and electronic device manufacturing. This dissertation …
Communication—The Development Of A Stable And Practical Saturated Reference Electrode For Molten Chloride Salt Systems, J. Marvin Torrie, Ranon Fuller, Devin Rappleye
Communication—The Development Of A Stable And Practical Saturated Reference Electrode For Molten Chloride Salt Systems, J. Marvin Torrie, Ranon Fuller, Devin Rappleye
Faculty Publications
A simply constructed, stable, Ni/Ni2+ saturated reference electrode (SRE) has potential to measure thermodynamic behavior of molten chloride salts more reliably. Like the Ag/Ag+ reference electrode (RE), the Ni/Ni2+ SRE is made of commercially available materials. Initial experiments in molten CaCl2 and LiCl show the Ag/Ag+ RE potential drifting two times faster than the SRE. Furthermore, experiments show the replicability of SREs by comparing two Ni/Ni2+ SREs with different compositions of NiCl2 which is supportive of saturated phase behavior.

The Battle Of King's Mountain: Making History In An Hour, Katelyn Thacker
The Battle Of King's Mountain: Making History In An Hour, Katelyn Thacker
The Thetean: A Student Journal for Scholarly Historical Writing
Heavy rain in the early morning hours of October 7, 1780, dampened the leaves and allowed the rebel militia to steal through the forest surrounding King's Mountain undetected. The loyalist corps on the top of King's Mountain became aware of the approaching enemy by the rebel's own gunfire scarcely half a mile away. Multiple units of patriot riflemen swarmed the footshaped hill, pushing the loyalist troops to one end of it. In vain, the loyalists attempted to counter showering gunfire with bayonet charges. After only one hour, the loyalist commander British Major Patrick Ferguson lay dead. His subordinate, loyalist Captain …
Distributed Conflict Detection And Optimal 4d Trajectory Resolution Leveraging Polynomial Based Methods, Michael Klinefelter, Austin Stone, Joshua Miller, Cameron K. Peterson, John Salmon
Distributed Conflict Detection And Optimal 4d Trajectory Resolution Leveraging Polynomial Based Methods, Michael Klinefelter, Austin Stone, Joshua Miller, Cameron K. Peterson, John Salmon
Student Works
This paper presents a methodology for distributed conflict detection and resolution of aircraft following time-dependent flight paths. We use parametric fifth-order polynomial splines to define the full, time-based paths of vehicles. This representation can be exploited to rapidly detect conflicts and calculate optimal resolution solutions that minimize deviations from the original path. Conflicts are identified using a Sturm sequencing procedure and resolutions are found using gradient-based optimization techniques. Simulations show the locally optimal resolution of complex multi-vehicle conflicts and large-scale scenarios. Also, a method of fitting the flight path model to data sets is presented and flight path trajectories are …

"Have Faith In God And U.S. Reclamation" Failure On The Boise Project, 1905- 1924, Jane Morgan
"Have Faith In God And U.S. Reclamation" Failure On The Boise Project, 1905- 1924, Jane Morgan
The Thetean: A Student Journal for Scholarly Historical Writing
The "destiny of man is to possess the whole earth," agricultural specialist John A. Widtsoe declared in 1928; "and the destiny of earth is to be subject to man."' Widtsoe's comment reflected the U.S. government's imperative to conquer and manage nature to fulfill the nation's destiny. Reclamation, the conversion of wasteland, usually arid deserts, into farmland, was a central program of the conservationist movement. A progressive government saw the West as the home of a future American empire where strong, independent households would unite to reclaim the land. Believing the Secretary of the Interior's promise that agricultural prosperity could be …
The Life Of Edward J. Logue And The Rebuilding Of America's Cities After Wwii, Lizabeth Cohen
The Life Of Edward J. Logue And The Rebuilding Of America's Cities After Wwii, Lizabeth Cohen
The Thetean: A Student Journal for Scholarly Historical Writing
Let's cut right to the chase: what's a social historian like me doing writing a biography of a dead white man named Edward J. Logue? I've never written a biography before. My two previous books, Making a New Deal and A Consumers' Republic, have made contributions to twentieth-century United States history by giving agency to social groups often considered powerless, such as industrial workers, first-generation immigrants, rank-and-file supporters of Franklin Roosevelt's New Deal, African American consumers, new suburbanites, and female consumer activists. I have made my reputation as a twentieth-century U.S. historian by arguing that ordinary Americans have been …

Rapid Industrialization And Slave Labor: The Economics Of The Soviet Gulag, 1928-1940, Jeffrey S. Hardy
Rapid Industrialization And Slave Labor: The Economics Of The Soviet Gulag, 1928-1940, Jeffrey S. Hardy
The Thetean: A Student Journal for Scholarly Historical Writing
Alexander Solzhenitsyn's epic work The Gulag Archipelago opened Western eyes to the unfathomable horror endured by millions of people in the forced-labor camps of the Soviet Union. Since then, countless books, articles, memoirs, etc., have been devoted to explaining the origins of the Gulag, the lives of convicts within this prison system, and the number of people who perished as a result of it. This last aspect in recent years has drawn a disproportionate amount of discussion within the scholarly (and nonscholarly) community, as if an exact number is necessary to compare Joseph Stalin with other brutal dictators, or to …

Specialized cancer treatments have the potential to exploit glutamine dependence to increase patient survival rates. Glutamine diagnostics capable of tracking a patient’s response to treatment would enable a personalized treatment dosage to optimize the tradeoff between treatment success and dangerous side effects. Current clinical glutamine testing requires sophisticated and expensive lab-based tests, which are not broadly available on a frequent, individualized basis. To address the need for a low-cost, portable glutamine diagnostic, this work engineers a cell-free glutamine biosensor to overcome assay background and signal-to-noise limitations evident in previously reported studies. The findings from this work culminate in the development …
Pleas For Toleration Against The Call Of Treason: The 1890 Shanghai Protestant Missionary Conference And The Controversy Over Chinese Rites, Joseph Seeley
The Thetean: A Student Journal for Scholarly Historical Writing
On May 7,1890, a colorful assortment of Western Protestant missionaries, stationed in all corners of late Qing-dynasty China, gathered in Shanghai for a thirteen-day mission conference. Some came to the conference clad in native Chinese dress, complete with Manchu-style ponytails or queues, while others were dressed more formally in the proper Victorian garb preferred by their non-missionary Western counterparts. Regardless of perceived differences in dress or ecclesiastical affiliation in the multi-denominational assembly, all sought to enjoy what was later described by conference organizers as "an occasion of the highest social enjoyment... as well as spiritual profit." As over four hundred …

Acoustofluidic Scanning Fluorescence Nanoscopy With A Large Field Of View, Geonsoo Jin, Neil Upreti, Joseph Rich, Jianping Xia, Chenglong Zhao, Tony Jun Huang
Faculty Publications
Large-field nanoscale fluorescence imaging is invaluable for many applications, such as imaging subcellular structures, visualizing protein interactions, and high-resolution tissue imaging. Unfortunately, conventional fluorescence microscopy requires a trade-off between resolution and field of view due to the nature of the optics used to form the image. To overcome this barrier, we developed an acoustofluidic scanning fluorescence nanoscope that simultaneously achieves superior resolution, a large field of view, and strong fluorescent signals. The acoustofluidic scanning fluorescence nanoscope utilizes the superresolution capabilities of microspheres that are controlled by a programmable acoustofluidic device for rapid fluorescence enhancement and imaging. The acoustofluidic scanning fluorescence …

A Bilevel Approach To Resource Allocation For Utility-Based Request-Response Systems, Tanner Jack Sundwall
A Bilevel Approach To Resource Allocation For Utility-Based Request-Response Systems, Tanner Jack Sundwall
Theses and Dissertations
We present a novel bilevel programming formulation that aims to solve a resource allocation problem for request-response systems. Our formulation is motivated by potential inefficiencies in the allocation of computational resources to incoming user requests in such systems. In our experience, systems often operate with a surplus of resources despite potentially incurring unjustifiable cost. Our work attempts to optimize the tradeoff between the financial cost of resources and the opportunity cost of unfulfilled user demand. Our bilevel formulation consists of an \textit{upper} problem which has a constraint value appearing in the \textit{lower} problem. We derive efficient methods for finding global …

Dissecting Trypanosome Metabolism By Discovering Glycolytic Inhibitors, Drug Targets, And Glycosomal Ph Regulation, Daniel Hale Call
Theses and Dissertations
Trypanosoma brucei, the causative agent of African trypanosomiasis, and its relatives Trypanosoma cruzi and several Leishmania species belong to a class of protozoa called kinetoplastids that cause a significant health burden in tropical and semitropical countries across the world. While an improved therapy was recently approved for African trypanosomiasis, the therapies available to treat infections caused by T. cruzi and Leishmania spp. remain relatively poor. Improving our understanding of T. brucei metabolism can inform on metabolism of its relatives. The purpose of the research presented in this dissertation was to develop novel tools and methods to study metabolism in T. …
Ionic Conductivity, Li+ Transference Number, And Diffusion Coefficient Of A Solid-State Electrolyte Composite, Lizbeth Zurita
Ionic Conductivity, Li+ Transference Number, And Diffusion Coefficient Of A Solid-State Electrolyte Composite, Lizbeth Zurita
Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)
The design of solid-state electrolyte (SSE) composites involves the fundamental study of transport properties, such as ionic conductivity. This transport property is influenced by the transport mechanisms of the charge species inside the composite, such as diffusion and migration. In this work, we perform the measurement of these three parameters through defined techniques. The resulting parameters were: ionic conductivity, the diffusion coefficient, and the Li+ transference number.

Model To Demonstrate Effects Of Mass Transfer And Applied Current In An Electrolytic Cell, George Ankrah
Model To Demonstrate Effects Of Mass Transfer And Applied Current In An Electrolytic Cell, George Ankrah
Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)
This study investigates the relationship between applied current and resulting cell potential in an electrolytic system, considering the transport of electroactive species. By applying Michael Faraday's laws of electrolysis and the Nernst-Planck equation, the behavior of electroactive species in diffusion-controlled systems with and without stirring is modeled. The plots demonstrate how stirring enhances ion transport and establishes a stable Nernst diffusion layer, affecting the kinetics of electrochemical reactions. Understanding these dynamics is crucial for optimizing electrolysis processes.

Model Of The Effect Of Voltage On Contact Angle In An Electrolytic Cell Reaction, Aaron Essilfie
Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)
This paper investigates the hypothesis that the contact angle at the meniscus of an electrode-electrolyte can be altered during a redox reaction through the coupled understanding of electrowetting and capillarity rise. Recent studies in electrowetting have focused on dielectric surfaces but research on contact angle at the electrode-electrolyte surface is lacking. The study employs a basic electrolytic cell. By applying principles of electrowetting and capillary rise the research aims to understand the relationship between applied voltage and contact angle, to advancements in electrochemistry and microfluidics.
