Increasingly, students choose to use general search engines for research rather than taking advantage of the resources provided by university libraries. As university libraries offer services such as the careful selection of material and subscriptions to peer-reviewed journals, it is important that the library become integrated into research workflows. Existing technologies on library servers do not provide the level of integration we believe is most helpful to users. LibX is a browser add-on designed to assist research by making library resources more accessible than they are through the library's own tools. It provides a client-side interface to these library services through the web browser. This integration enhances productivity and augments the user's existing information-seeking behavior. We extended the existing Firefox version of LibX into a browser-agnostic framework, allowing LibX services to be provided on multiple browser platforms. We created a toolbar and context menu system, written in C#, to extend the existing LibX features to the Internet Explorer web browser. The primary focus of this work is on the software engineering challenges presented in creating this version. We also designed a new framework for web localization, allowing pages viewed by the user to be modified on the client side by rules written by LibX developers, library staff, or individual users. The framework also provides a way for these rules to be distributed, updated, and composed, enhancing the browsing experience by augmenting it with additional information. The design and behavior of this framework is a secondary focus of this work. / Master of Science

The Explorer 33 satellite was launched July 1, 1966 and was injected into a highly elliptical earth orbit. The Goddard Space Flight Center magnetic field experiment onboard the spacecraft consists of a triaxial fluxgate sensor with a maximum dynamic range of ±64 gammas and a sensitivity of ±0.25 gammas along each axis. Because of the initial apogee-earth-sun angle of 118° west of the sun, the first 8 orbits of Explorer 33 (July-November 11, 1966) mapped the earth's magnetosheath and magnetic tail from the western flank of the bow shock to the eastern flank. This mapping of the geomagnetic tail out to 80 earth radii established that the tail extends beyond the lunar orbital distance. Explorer 33 has also found that the earth's bow shock is still a detectable boundary between the interplanetary magnetic field and the downstream magnetosheath at a geocentric distance of 75.7 earth radii. This spacecraft has further revealed that the cross-section of the geomagnetic tail is probably not cylindrical, and that the magnetic field magnitude in the tail decreases with distance down the tail from the earth. This magnitude decrease can be due both to a gradual expansion of the tail with distance and to a reconnection of magnetic field lines across the tail neutral sheet. / M.S.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Reducing spacecraft ground system operations costs are a major goal in all missions. The Fast Auroral Snapshot (FAST) flight operations team at the NASA/Goddard Spacecraft Flight Center developed in-house scripts and procedures to automate monitoring of critical spacecraft functions. The initial staffing profile of 16x7 was reduced first to 8x5 and then to “lights out”. Operations functions became an offline review of system performance and the generation of future science plans for subsequent upload to the spacecraft. Lessons learned will be applied to the challenging Triana mission, where 24x7 contact with the spacecraft will be necessary at all times.

Företaget GUTAB använder idag en frågeanalysmodul som är utvecklat i Visual Basic for Applications i Microsoft Excel. GUTAB fann det intressant att veta om modulen kunde konverteras till webbläsaren Internet Explorer samt vilken teknologi som var lämplig för detta. GUTAB var även intresserade av att veta vilken teknologi som kunde användas för att skapa grafiska manipulerbara objekt.En skrivbordsundersökning genomfördes som omfattade teknologierna ASP, ASP.NET, JSP, PHP, ActiveX samt Java applets. Skrivbordsundersökningen utgjordes av två delar där den första delen redogjorde för de två klientbaserade teknologierna ActiveX och Java applets med vilka grafiska manipulerbara objekt kunde realiseras. GUTAB ansåg att ActiveX program var mest lämpliga för detta ändamål.Baserat på skrivbordsundersökningens andra del bestämde GUTAB att ASP och ASP.NET skulle användas för att testa teknologiernas kapacitet att konvertera programlogik samt grafiska objekt från VBA-applikationen i en webbapplikation då dessa två teknologier ansågs som mest lämpliga för en konvertering.Testet som genomfördes visade att det var fullt möjligt att konvertera utvald funktionalitet med båda teknologierna. Dock kunde inte grafiska objekt skapas i asp varför befintliga objekt användes för det ändamålet. Många fördelar identifierades med ASP.NET varför GUTAB beslutade att ASP.net var den mest lämpliga teknologin att använda vid en eventuell konvertering.

Meteorological and other multidimensional, georeferenced data is used extensively in science and engineering. These datasets are produced, shared, and used by organizations all over the world. Conventions have been developed specifying the metadata and format of these datasets in an effort to standardize the data and make it compatible with current and future software and web services. By necessity, the conventions are complex and difficult to implement correctly, resulting in useful datasets that are unusable in many applications due to lack of compliance with the conventions. By programmatically assigning metadata and guiding the dataset creator through the dataset creation process, convention compliant datasets can be consistently and repeatably created by people with a limited knowledge of the standards. These datasets can then be used in any application that supports the specific standard. This paper examines the process of building multidimensional, georeferenced netCDF datasets that are compliant with the Climate and Forecast Conventions and presents a new python package called cfbuild that automates the process of making the datasets compliant.

Objectives: Subgingival dental calculus is recognized as an important contributing risk factor in the initiation and perpetuation of inflammatory forms of human periodontitis, and its removal from diseased tooth root surfaces constitutes a critical clinical end-point in periodontal therapy. As a result, the reliable detection of subgingival dental calculus on tooth root surfaces is of paramount importance in periodontal diagnostics. A wide range of manual dental instruments have been employed to detect by tactile sensation the presence of subgingival dental calculus deposits on teeth. However, the Old Dominion University (ODU) 11/12 dental explorer is presently used by all regional dental licensure examining boards in the United States to identify subgingival dental calculus on patients. Interestingly, little data is presently available to validate the ability of the ODU 11/12 dental explorer to reliably discriminate between dental calculus- positive and –negative tooth root surfaces. As a result, the purpose of this study was to to assess, with an in vitro typodont model system, the ability of an ODU 11/12 dental explorer to accurately identify subgingival dental calculus on tooth root surfaces. Methods: A total of 108 subgingival sites on mandibular posterior plastic teeth, of which 73 (67.6%) exhibited artificial dental calculus deposits, were mounted within on typodont models of the human oral cavity, comprised of white plastic teeth emerging from and surrounded by anatomically-accurate pink silicone gingival and palatal soft tissues. Each typodont was attached to a phantom head with simulated soft tissue mouth shrouds. Sheep blood was irrigated into subgingival and interproximal areas around ii typodont teeth to simulate gingival tissue inflammation, and artificial saliva applied onto supragingival typodont tooth surfaces to further simulate typical oral cavity conditions in humans. The 108 test subgingival surfaces were then evaluated for subgingival dental calculus with an ODU 11/12 dental explorer in duplicate by a primary examiner, who was a board-certified periodontist with 30 years of clinical specialty experience. A periodontist initially educated as a dental hygienist and possessing 45 years of combined dental hygiene-periodontics clinical experience, scored all of the test subgingival tooth surfaces once as a secondary examiner. The diagnostic performance of the ODU 11/12 dental explorer, relative to in vitro detection of subgingival dental calculus, was assessed among all test root surfaces, as well as among proximal and non-proximal root surfaces, with calculations of sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood value, negative likelihood value, diagnostic odds ratio, accuracy (diagnostic effectiveness), and Youden’s Index. Results: As utilized by the primary examiner, the ODU 11/12 dental explorer yielded a sensitivity of 91.2%, specificity of 78.4%, positive predictive value of 82.5%, negative predictive value of 88.9%, positive likelihood value of 4.2, negative likelihood value of 0.1, diagnostic odds ratio of 38.5, accuracy (diagnostic effectiveness) of 85.2%, and Youden’s index value of 0.70, for in vitro detection of subgingival dental calculus. Similar diagnostic test findings for the ODU 11/12 dental explorer were found on proximal (mesial and distal) and non-proximal (buccal and lingual) root surfaces, with accuracy (diagnostic effectiveness) values attained of 82.4% and 84.3%, respectively. Good reproducibility (kappa = 0.62) was found in duplicate scoring by the primary examiner of subgingival dental calculus with the ODU 11/12 dental explorer. The iii secondary examiner produced even better performance outcomes with the ODU 11/12 dental explorer, providing a sensitivity of 91.2%, specificity of 86.3%, positive predictive value of 88.1%, negative predictive value of 89.8%, positive likelihood value of 6.7, negative likelihood value of 0.1, diagnostic odds ratio of 66.5, accuracy (diagnostic effectiveness) of 88.9%, and Youden’s index value of 0.78, for in vitro detection of subgingival dental calculus. Similar to the primary examiner, the secondary examiner also found relatively close agreement in diagnostic test findings for ODU 11/12 dental explorer on both proximal and non-proximal root surfaces, with accuracy (diagnostic effectiveness) values attained of 85.2% and 92.6%, respectively. A good level of agreement (kappa = 0.62) was found between the primary and secondary examiners in their in vitro scoring of subgingival dental calculus with the ODU 11/12 dental explorer. Conclusions: These study findings provide important in vitro validation for continued use of an ODU 11/12 dental explorer for detection of subgingival dental calculus on dental licensure examining board examinations. The ODU 11/12 dental explorer exhibited a high level of in vitro discrimination between subgingival dental calculus-positive and calculus-negative tooth root surfaces in a typodont model system with experienced periodontist examiners. The ODU 11/12 dental explorer performed with a similar high level of diagnostic accuracy on both proximal and non-proximal tooth root surfaces, and exhibited good reproducibility in duplicate assessments made by the primary examiner, and showed good agreement between evaluations made by the primary and secondary examiners. Based on these in vitro findings, routine clinical utilization of the ODU 11/12 dental explorer in dental practice for the detection of subgingival dental calculus is recommended. / Biology

The deep sea is the largest ecosystem on the planet, comprising more than 90% of the volume that life can inhabit, yet it is the least explored biome in the world. The deep sea includes the benthos, which makes up 91.5 % of all the seafloor globally, and the water column deeper than 200 meters. It hosts a wealth of ecosystems including deep-sea vents, seamount coral gardens, abyssal plains, high-productivity whale falls, and life even in the deepest trenches. We now understand that all of these ecosystems host a variety of habitats, each with their own ecology and unique species. These ecosystems and habitats- and their associated biodiversity- provide essential ecosystem services such as carbon sequestration, nutrient regeneration, microbial processes detoxification, fisheries provisioning, and many others. However, despite the uniqueness of these ecosystems and the importance of the services they provide, we still know far less about them than we do about their shallow water and terrestrial counterparts. In this dissertation, I contribute new insights about the patterns of biodiversity in the Pacific Ocean across a large geographic area, and across a wide range of depths. To that end, in Chapter 1, I have used one of the largest ocean exploration datasets to look for patterns of the abundance and diversity across the most common benthic invertebrate families found on Pacific seamounts: Anthozoa, Porifera, and Echinodermata across the Central and Western Pacific. In addition to quantifying the diversity and abundance of known taxa, I also documented patterns of as-of-yet unidentified taxa by region, depth, and deepwater feature (seamount shape). Building on patterns associated with seamount shape that were described in Chapter 2, I focused on the effect of seamount shape on the diversity and abundance of deep-sea coral communities in Chapter 3. The analysis presented in Chapter 3 provides strong support for the novel hypothesis that gross seamount morphology is a significant driver of community composition. In Chapter 4, I focused on a single seamount to investigate biodiversity and abundance of coral and sponge taxa on a finer spatial scale, examining the role of direction (N, S, E, W) on different flanks of a single equatorial seamount. This analysis yielded interesting consistent patterns of zonation on all sides of the seamount in terms of depth, but with differences in abundance patterns on each flank for individual taxa. Finally, in Chapter 5, I took a global perspective to investigate gaps in deepwater data, with the goal of determining what regions need further exploration to conclusively determine patterns of deep-sea biodiversity, which will be critical for determining the health of deepwater ecosystems under climate change conditions with increased exploitation pressure and cooccuring with increased conservation efforts. Merging Ocean Biogeographic Information System (OBIS) records with the largest collection of deep submergence dive records ever collected, I used proposed biogeographic provinces schema to identify areas with the least supporting data. Additionally, I coupled records from OBIS with climate change projections to identify the areas with the fewest number of biodiversity records that are likely to change the fastest under different IPCC projections. These areas of low number of records and high likelihood of change by the end of the century should become priority targets for future exploration. Taken together, this dissertation provides valuable insights and generates new hypotheses about patterns and drivers of deep-sea biodiversity, and puts forth recommendations for future research and exploration efforts.
