Re-envisioning Reclamation: A Strip Mine's BiographyMorris, Bethany Margaret 01 August 2011 (has links)
ABSTRACT
This proposal is a study of coal-mining in Southern West Virginia; its impact on the landscape; local economy and culture; and presents an alternative land use to address the loss of a major industry in a rural county.
The study began with understanding the process of mining; from the actual extraction to the end product, electricity. Looking at the past provided a historical metric for the Coal Company - Mine Worker dynamic. Case studies created benchmarks for both appreciating and improving upon the issue. Constructing a timeline that tracked political, social and natural occurrences gave scope to the interrelationships of government, industry and the working class. Current reclamation practices take into account the physical changes made to the land, but not the void the loss of industry will create in the local economy. Recognizing coal mining as an important part of Appalachian culture means re-envisioning reclamation, and understanding more than the land needs to be restructured when a mine closes.
Coal mining reclamation has been studied by engineers, ecologists and political bodies more so than by the design community: architects, landscape architects and artists. However, the designer’s training for not just research and analysis but synthesis of ideas and collaboration between disciplines that could provide the next step for a changing industry.

Analysis of high-speed vessels for Seventh Fleet logistics supportMorgan, Eric A. 03 1900 (has links)
Approved for public release, distribution is unlimited / Commander, Logistics Group, Western Pacific (COMLOGWESTPAC) is concerned with the delivery of high priority material, ordnance, and passengers to U.S. Navy ships due to a very large operations area and limited Combat Logistics Force (CLF) assets. High-speed vessels (HSVs) may have the potential to improve the delivery of these materials when used to complement existing logistics shuttle ships. This thesis quantifies current levels of traditional naval logistics support and provides comparison to HSV-based alternatives in various scenarios. The CLF Scenario Analysis Tool (CLFSAT), a newly developed discrete event simulation model of naval logistics support, performs the analysis. Given a scenario depicting combatant movements and operations, CLFSAT provides insight into the comparative performance of different supporting naval logistics force structures. This analysis determines that HSVs can be effective logistics platforms in specific scenarios when distributing high priority material, ordnance, and stores. HSVs are very effective in small theaters with short transit distances, but for larger theaters, their effectiveness is inversely proportional to distance from the Forward Logistics Site. Regardless of theater size, HSVs show significant improvements in theater distribution of "low density, high priority" cargo, such as precision guided munitions (PGMs) or critical repair parts when customers are outside COD range. / Lieutenant Commander, United States Navy
