The work in this thesis is concerned with the generation of Lumped Parameter Models (LPM) for two, slender, torpedo shaped, X-fin craft. This process involves the use of CFD to simulate captive maneuvers that are normally performed using test equipment in the field. These captive maneuvers are refereed to as planar motion mechanisms (PMM), and when simulated through CFD are refereed to as virtual planar motion mechanisms (VPMM). The results from VPMM are used to determine the hydrodynamic derivatives that inform the LPM. There was some inconsistency in the VPMM data based on the frequency and amplitude that the VPMM was run. A brief study was run to look at this effect. Afterwards, Open and closed loop, autopilot assisted, maneuvers are implemented and performed using the LPM model through Simulink. Results of these maneuvers are analyzed for craft stability. Additionally, comparisons of LPM maneuvers to field data are performed. Critiques of the craft stability and effect of the autopilot are made. / Master of Science / The work carried out in this thesis involves the creation of a physics based model of an underwater craft. This physics based model is informed through characteristics determined by running computational fluid dynamics (CFD) simulations. The benefit of such a model, is the simplification from CFD to a 6 degree of freedom (6-DOF) lumped parameter model (LPM). These physics models, LPM, are generated for two particular craft of interest. One craft is an existing design used by NUWC (named Tonnetto), while the other design is one generated to be similar in shape and size to the NUWC craft (named Hokie). Computer simulated maneuvers are carried out using these models to asses craft stability and performance. An autopilot is implemented into the models for some of these simulations to see its affects on the crafts performance. Additionally, these simulated maneuvers are compared to field data collected by NUWC.

La noción del infinito en un punto se entrevé en innumerables textos de Jorge Luis Borges. En ellos está el espectro del Aleph y sus variantes apócrifas, engendros homólogos que, en mayor o menor grado, abarcan el laberinto de la eternidad. Las revelaciones del Aleph, sin embargo, conllevan un fin irrefutable: el olvido, la muerte; dos caras del fin del mundo. El Aleph borgeano, además, se asoma de alguna u otra manera por algún resquicio de la literatura moderna. El presente trabajo se centra en dos ejemplos de escritores recientes: Jaime Collyer y Rodrigo Fresán. En la narrativa de ambos encontramos manifestaciones de Alephs apócrifos, parciales, imperfectos; Alephs espurios que, al igual que su referente borgeano, vislumbran un destino insoslayable: el fin del mundo, el olvido absoluto. Un fin que, sin embargo, no representa el final de todo lo que existe, sino el inicio de un nuevo ciclo. En el presente estudio —que abarca diversos textos de Borges, mayormente “El Aleph” y “La escritura del dios”; “Ángel dormido” y “Golpe a golpe” de Collyer; y El fondo del cielo de Fresán— el Aleph se manifiesta íntimamente vinculado al acto de recordar. El tiempo y el espacio que surcan el Aleph aluden al abstracto tejido espacio-temporal de la memoria, que conforma un tumulto simultáneo de tiempos heteróclitos y coexistentes en espacios inmateriales. De manera que las revelaciones del Aleph y de los múltiples Alephs apócrifos funcionan como la memoria que abarca el infinito, pero que presagia un fin inevitable, ya que todo recuerdo cede indefectiblemente al desgaste del olvido. Tal es la naturaleza de la revelación del fin del mundo en el Aleph: manifestar la supremacía absoluta de aquella muerte que es el olvido. El olvido que, sin embargo, acaso es la vedada y silenciosa puerta hacia una revelación superior.

In this thesis I explore the importance of elite women in early twentieth-century Vienna in relation to the Wiener Werkstätte. My research has led me to believe that the Werkstätte held a more egalitarian view of women than other contemporary European applied arts workshops. Unfortunately the art-historical canon has generally overlooked the applied arts of the Wiener Werkstätte, as well as the significant roles of women in the Werkstätte as artists, clients, patrons, and promoters. In this thesis, I consider cases of women in these roles in early twentieth-century Vienna in order to gain a greater understanding of Viennese women's place economically and politically, as well as socially and culturally. In particular, I examine the Werkstätte's primary records of sales and production (called model books), housed in the Wiener Werkstätte archives at the Austrian Museum of Applied Arts in Vienna, as a means to better understanding their participation. The evidence of the importance of women in relation to the Wiener Werkstätte, includes: 1) the creation of new opportunities for women in the arts; 2) the emergence and popularity of a liberating reformed fashion; 3) the focus of the Werkstätte on creating objects that would appeal to a female clientele; and 4) the Werkstätte's success, particularly among prominent wealthy female art patrons. I conclude that women's roles as artists, clients, patrons, and promoters can be seen as positions of empowerment for Viennese women of the early twentieth century.

The effects of water and dietary influence, and time duration for discernment, of pectoral fin spine 87Sr/86Sr were evaluated in Atlantic Sturgeon Acipenser oxyrinchus oxyrinchus. Fish were subjected to 87Sr-enriched water (0.1 mg/L) or diet (0.25 migrogram/g or 0.5 microgram/g) for 1, 2, 3, 6, or 12 weeks. Fish were also held at 15 or 25°C to determine if temperature influenced 87Sr/86Sr. Results found fin spine 87Sr/86Sr changed in water after 1 week and diet after 12 weeks suggesting water is the primary influence. In wild Gulf Sturgeon A. o. desotoi, spot ablations closest to the fin spine core separated fish into four 87Sr/86Sr groups (0.7110, 0.7105, 0.7100, and 0.7906) for both the Pascagoula and Pearl Rivers from 2016-2021. In the Pearl River system, 87.5% of fish (pre-first annuli) had stable 87Sr/86Sr indicating minimal movement, whereas decreasing 87Sr/86Sr in the second and third growth zones indicated downriver movement towards estuaries.
