The Growth Of Starry Stonewort (Nitellopsis Obtusa), An Aquatic Invasive Species, In Two Michigan Lakes, And Its Suitable Habitats In The Midwest And Northeast United States, Emily Neuman

Masters Theses

The growth of starry stonewort (Nitellopsis obtusa), an aquatic invasive species, in two Michigan Lakes, and its suitable habitats in the Midwest and Northeast United States Aquatic invasive species are a major threat to freshwater ecosystems, but gaps remain in our knowledge on how these species invade, grow, and thrive. This thesis aims to understand how an invasive macroalga, Nitellopsis obtusa (starry stonewort), grows within the littoral zone of two drowned river mouth lakes and suitable habitat preferences across 17 Midwest and northeast U.S.A. states to aid in aquatic invasive species management. In chapter II of this thesis, …

Towards An Efficient, Scalable Stream Query Operator Framework For Representing And Analyzing Continuous Fields, John Whittier

Electronic Theses and Dissertations

Advancements in sensor technology have made it less expensive to deploy massive numbers of sensors to observe continuous geographic phenomena at high sample rates and stream live sensor observations. This fact has raised new challenges since sensor streams have pushed the limits of traditional geo-sensor data management technology. Data Stream Engines (DSEs) provide facilities for near real-time processing of streams, however, algorithms supporting representing and analyzing Spatio-Temporal (ST) phenomena are limited.

This dissertation investigates near real-time representation and analysis of continuous ST phenomena, observed by large numbers of mobile, asynchronously sampling sensors, using a DSE and proposes two novel stream …

Gis Analysis Of Brownfield Sites In The City Of Minneapolis, Shreya Vaidya

All Graduate Theses, Dissertations, and Other Capstone Projects

Brownfield sites have many negative ramifications on a local area which includes loss of economy, decline in land use value and potential hazard to human health and the environment. Despite the efforts on redeveloping brownfields, Minnesota Pollution Control Agency (MPCA) claims that over 10,000 known contaminated or potentially contaminated sites remain across Minnesota and thousands are likely to exist but have not been identified and recorded. The objectives of this study are to map the brownfield sites in Minneapolis based on the information provided by the regulatory sources and to categorize and analyze all the sites on the basis of …
