Discovering Predictors Of Readmission For Acute Myocardial Infarction In A Medicare Population: A Data Mining Approach, Daniel Macdonald Knowles Ms

All Student Scholarship

Health care costs in the United States have risen at rates far exceeding the cost of living for many years. Previous attempts to control these costs have proven futile. Studies have shown that high per-capita spending in the U.S. does not equate to consistent quality of care or better outcomes.

Wind Pattern Effects On The Southern Shetland Islands, Helen Pottle

Thinking Matters Symposium Archive

The Shetland Islands, northeast of Scotland, experienced an unusually extreme storm that caused unique sand shifting patterns and sand dune formations that resulted in the destruction of the Village of Broo. There is little existing information about the weather and terrain of the Shetland Islands during the extreme storm that was estimated to have occurred between 1650 and 1670. WindNinja, a wind model originally developed for wildland fire application, was used to understand the wind patterns that may have caused the unique sand patterns and resulting destruction. It incorporates existing terrain elevations and vegetation as well as average wind speed …

The Physics Of A Space Elevator, Trevor Hamer

Thinking Matters Symposium Archive

A space elevator is a hypothetical device consisting of a long cable attached to the surface of the earth that extends upward into space. Its purpose is to provide a tether on which a vehicle could be lifted up into orbit, greatly reducing the cost of space travel. This project explains the physical forces acting on the elevator along with the kinds of materials required to keep such a cable intact. It also examines different design aspects, as well as potential problems facing the construction and usage of the elevator, and whether or not it is something we should expect …

Identification Of Slums In Mumbai, India: Unsupervised Classification Techniques, Frankie St. Amand

Thinking Matters Symposium Archive

Slums are contiguous settlements. Inhabitants lack access to safe water, sanitation and sewage infrastructure, secure housing tenure, uncrowded living space, and permanent, durable housing. Addressing these problematic trends begins with identifying contiguous settlements within Mumbai’s urban fabric. Classifications can be performed using satellite images and remote sensing techniques to yield accurate results. Through literature reviews, socio-cultural analysis, and examination of high resolution satellite imagery, this project aims to develop a systematic, accessible, and reproducible method of classifying Mumbai’s slums.

Building Footprint Extraction: A Land Use Classification Comparison Of Satellite Imagery Vs. Orthoimagery, Elisa Trepanier

Thinking Matters Symposium Archive

The Town of Windham, Maine Proposed Municipal Budget FY 2012-2013 called for $12,750 for professional services to develop a building footprint database. There are several municipal applications for building footprints including, but not limited to: Taxation/valuation of properties; setbacks for code enforcement; public safety planning; historical analysis of building patterns; general planning, where to encourage growth and redevelopment; zoning analysis and recreational planning. Due to the town’s in-house GIS (Geographic Information Systems) capabilities, the project will be developed within the Assessor’s Office and based on the 2012 Maine Office of GIS 6 Orthoimagery for Windham. The following is an effort …

Identifying High Crime Areas Using Spatial Analysis, Elisa Trepanier

Thinking Matters Symposium Archive

Crime incident locations and trends are examined spatially using GIS to produce maps that pinpoint high crime areas or Hot Spots Crime mapping aids police departments by identifying areas to allocate limited resources where and when they are most needed. This project introduces the availability of GIS technology to smaller police departments as a tool to assist in the development of crime prevention strategies. In this model crime incident reports for Windham, Maine are geocoded and patterns of motor vehicle and structure burglaries analyzed for date, time and location of incident. An addressing protocol is followed to protect victim privacy …

Obesity Rates In Maine Exceed New England's Obesity Rate: A Look At Possible Contributing Factors, Susan Walker

Thinking Matters Symposium Archive

The purpose of this study was to explore adult obesity data to: Compare Maine’s rates with other New England states and explore differences in Maine counties by looking at known risk factors.

Effects Of Digital Elevation Model Resolution On Estimates Of Flood Damage In Westbrook, Maine, Scott Webber

Thinking Matters Symposium Archive

Accurate predictions of flood damage and economic losses are increasingly important as historically low-probability floods have become more common. Digital elevation models (DEMs) are essential to flood modeling as they define stream channel and floodplain morphology, the accuracy of which influence estimates of flood damage. The city of Westbrook, Maine experiences episodic flooding of the Presumpscot River; therefore, flooding in Westbrook was simulated with HAZUS, a model created by the Federal Emergency Management Agency. The model is designed to assess the costs associated with hazard scenarios including riverine flooding. HAZUS was run for a 100-year return period flood with both …

Stream Crossing Barrier Prioritization Methods For Increasing Eastern Brook Trout Habitat In The Little Androscoggin River Watershed, Michele Windsor

Thinking Matters Symposium Archive

Eastern Brook Trout (Salvelinas fontanalis) are an important cold water fishery in the state of Maine. While populations in Maine are relatively abundant there has been decline in some parts of its range due in part to loss of habitat connectivity. Brook trout require access to specific types of stream habitat for spawning, feeding, and seasonal thermal refuges. Stream crossing structures such as undersized, poorly installed, or blocked culverts, as well as small remnant dams, can create barriers to accessing important stream habitat for brook trout. A recent Fish Barrier/Culvert Survey in the Little Androscoggin River Watershed provided data about …

Natural Gas Service Expansion Criteria In Maine, Kevin Mahaffey

Muskie School Capstones and Dissertations

The purpose of this study is to gain an understanding of the framework used by Maine’s natural gas utilities in making decisions to expand natural gas infrastructure and service to new customers,and then to apply this knowledge in an attempt to identify municipalities that are potentially attractive candidates for service expansion within Maine.

This study is not a precise model for gas utilities, but is meant rather to be a reconnaissance study for finding viable and attractive candidates for service.This study was limited both by resources and the inaccessibility of proprietary information.
