Examples of such applications include citizen journalism, events detection and analysis, geo-targeted advertising, medical research, and studying social influences in social sciences. Building such applications require data management infrastructure to deal with microblogs, including data digestion, indexing, and main-memory management. The lack of such infrastructure hinders the scalability and the widespread of such applications especially among users who are not computer scientists. This thesis proposes Kite; an end-to-end system that is able to manage microblogs data at a large scale. Using Kite, developers and practitioners can simply write SQL-like queries without worrying about the internal data management issues. Internally, Kite is equipped with scalable indexing and main-memory management techniques to support top-k temporal, spatial, keyword, and trending queries on both very recent data and historical data. Kite indexer supports scalable digestion and retrieval for incoming fast data in real time. Recent data are digested in efficient main-memory index structures. Kite in-memory index structure are able to scale up a single machine indexing capabilities to handle the overwhelming amount of data in real time. Meanwhile, Kite memory manager is monitoring the memory contents and smartly decides on which data is regularly moved to disk. This is accomplished through effective memory flushing policies that are designed for top-k query workloads, which are popular on microblogs data. Both in-memory and in-disk data are queried seamlessly through efficient retrieval techniques that are encapsulated in Kite query processor. The query processor exploits the top-k ranking function to early prune the search space and reduce the query latency significantly. Kite is open-sourced and available to the community to build on (http://kite.cs.umn.edu). Extensive experimentation on different Kite components show the efficiency and the effectiveness of the proposed techniques to manage microblogs data at scale.Item Minnesota Phosphorus Loss: How Soil Loss Is Only Part of the Story and Why Modeling Can Be Improved by Considering Subsurface Phosphorus Loss(2021-05) Reitmeier, HeidiThis study explores 20 years of Minnesota regional phosphorus (P) management data across agricultural landscapes and how these are modeled by the Minnesota Phosphorus Index (MNPI). Nutrient-loading and farm management records from 1999-2019 were compiled across 17 different Minnesota counties representing 5 different state regions, including sites from Discovery Farms of Minnesota, Minnesota Department of Agriculture, Minnesota Agricultural Water Resource Center, and the University of Minnesota. The consolidated data cover two critical watersheds in nutrient management, one flowing north to Canada's Lake Winnipeg, the other flowing south through the Mississippi River ultimately to the Gulf of Mexico. Best management practices are needed for P loss within these watershed basins due to rising concerns about recurrent algal blooms in both watersheds. This study combines historical nutrient-loading data and farm management data to see how soil loss due to erosion impacts P losses and how the MNPI models P-loss risk.Item Reel consequences: chasing the trace, leaving it behind(2012-10) Bonine, L. LelaineThis dissertation investigates the definition of film as an indexical sign. It argues against such a definition, alleging that it is not only logically unsound, but harmful to practical applications of fandom and cinephilia. Chapter 1, therefore, attempts to unseat the index. Chapter 2 investigates the repercussions of the indexical definition on the practice of cinephilic pilgrimage. Chapter 3 examines fan fiction as an alternative practical application of fandom, existing exclusive of the index. And chapter 4 examines social cinephilia and celebratory viewing practices as the ultimate alternative satisfaction.Item Summary Report of the Natural Resources Research Institute’s Contribution to the Interagency Minerals Information Indexing Project(University of Minnesota Duluth, 1999-07) Oreskovich, Julie A; Heine, John J; Hauck, Steven AThe purpose of this interagency project is to provide public online access, in standardized form, to the multitude of reports, documents, and maps produced or held by the three public minerals agencies in Minnesota, i.e., the Minerals Division of the Minnesota Department of Natural Resources (MDNR), the Minnesota Geological Survey (MGS), and the Natural Resources Research Institute (NRRI). Initial work on the indexing project is focused in the area of non-ferrous minerals to better serve this exploration industry. The scope of NRRI’s part in the project extends to indexing all published reports on nonferrous minerals projects undertaken by NRRI since its inception in 1983. These include 21 reports published at NRRI and 3 reports published at NRRI’s Coleraine Minerals Research Laboratory (CMRL). The reports are listed in Appendix A and referenced by NRRI report number. Report numbers beginning with “CMRL” are held at NRRI’s Coleraine facility (Coleraine Minerals Research Laboratory, Natural Resources Research Institute, University of Minnesota, Duluth, Box 188, Coleraine, MN 55722). In addition to indexing its non-ferrous reports, NRRI is responsible for starting a Locality Thesaurus—a listing of geological names and terms associated with a physical locality, such as “Virginia Horn,” “Duluth Gabbro Complex,” “Vermilion District,” and “Camp Rivard Fault.” This thesaurus will be used as a foundation from which a fully cross-referenced locality thesaurus for the State of Minnesota will be built. Multiple names applied to any particular “locality” are crossreferenced. Initial efforts are concentrated in the non-ferrous area, but include ferrous and glacial locality terms as well.Item Technologies in Context: A Bibliography and Index to the works of David E. Nye(2021-05) Nye, David E.David E. Nye received the Leonardo da Vinci Medal in 2005 for his life's work from the Society for the History of Technology, and his other awards include a knighthood by the Queen in Denmark. His writings focus on technology in American culture. This index covers 14 books, 38 journal articles, and 63 book contributions, or roughly 5,500 pages, published between 1974 and May 2021. The bibliography also includes: 8 edited scholarly books (c. 2,000 pages), 7 textbooks (c. 1,200 pages), 6 translations into other languages, 8 encyclopedia articles, 66 book reviews, teaching materials, interviews, minor works that are difficult to obtain, and non-academic writings. The bibliography provides more details and better organization than one can get from search engines such as Google, which often present misleading or incomplete references and point to only one or two publications, and not necessarily the most important ones on a topic. The index is far more complete. It lists more than 30 sub-headings under automobile, pollution, or tourism, and more than 50 under city, General Electric, photography, railroad, or technology. There are also headings for theoretical topics such as aesthetics, determinism, landscape, narrative, nature, second creation, social construction of reality, space, technological momentum, and unintended consequences.
