Stealthy River Navigation In Jungle Combat Conditions, Fabio Ayres Cardoso Mar 2010

Stealthy River Navigation In Jungle Combat Conditions, Fabio Ayres Cardoso

Theses and Dissertations

One of the biggest challenges for Brazilian military logisticians is to support effective jungle warfare for both real and training operations carried out by their combat forces in the Amazonian region. The jungle's heat, humidity, and dense vegetation put significant demands on the supply chain. Further, because of the difficulties of land or air transportation, water transport is the most reasonable transportation option to sustain these deployed forces. Planners must select from among the available watercourses those whose surroundings provide stealthy navigation to the combat force location where the requested supplies can be safely unloaded. We seek a method of …


Screening And Sufficiency In Multiobjective Decision Problems With Large Alternative Sets, Michael D. Cote Mar 2010

Screening And Sufficiency In Multiobjective Decision Problems With Large Alternative Sets, Michael D. Cote

Theses and Dissertations

Portfolio selection problems with combinatorially-large alternative sets can be impossible to evaluate precisely on a reasonable timescale. When portfolios require complex modeling for performance assessment, prohibitive computational processing times can result. Eliminating a small number of alternatives through an intelligent screening process can greatly reduce the number of alternative combinations, thereby decreasing a problem's evaluation time and cost. A methodology was developed for the class of hierarchical portfolio selection problems in which multiple objectives are all judged on the same sub-objectives. First, a novel capability-based alternative screening process was devised to identify and remove poor alternatives, thereby reducing the number …

Development Of A Flapping Wing Design Incorporating Shape Memory Alloy Actuation, Jeffrey A. Barrett Mar 2010

Development Of A Flapping Wing Design Incorporating Shape Memory Alloy Actuation, Jeffrey A. Barrett

Theses and Dissertations

This research sought to validate a proof of concept regarding shape memory alloy actuation of a flapping-wing blimp. Specimen wires were subjected to cyclic voltage at increasing frequencies to quantify expected strains. A laser vibrometer captured 2048 sample velocities during single contraction and elongation cycles, and the resulting samples were used to calculate displacements. Displacements were determined ten times for each specimen and frequency to compute averages. Subsequently, a circumventing frame was designed to encase a blimp envelope and provide support for a flapping motion actuation system. Contraction of shape memory wire translated force to the flapping mechanism via bellcranks, …

Predators Over Pakistan, Kenneth Anderson Mar 2010

Predators Over Pakistan, Kenneth Anderson

Scholarly Articles in Law Reviews & Journals

American University, WCL Research Paper No. 2010-06 Abstract: This extended policy/political essay argues that targeted killing, by means of unmanned aerial vehicles such as Predator "drones" and including targeted killing as carried out by the CIA, is both a good policy in combating transnational terrorism and a lawful means of self-defense under international law. Lengthy (for a political magazine, at 8,000 words, but easier to read in this pdf format) and unabashedly polemical, the essay urges the Obama administration's lawyers to step up publicly and articulate their views of the legality of targeted killing, and further argues that they need …

Alkylresorcinol Synthases Expressed In Sorghum Bicolor Root Hairs Play An Essential Role In The Biosynthesis Of The Allelopathic Benzoquinone Sorgoleone, Daniel Cook, Agnes M. Rimando, Thomas E. Clemente, Joachim Schroder, Franck E. Dayan, N. P. Dhammika Nanayakkara, Zhiqiang Pan, Brice P. Noonan, Mark Fishbein, Ikuro Abe, Stephen O. Duke, Scott R. Baerson

Center for Plant Science Innovation: Faculty Publications

Sorghum bicolor is considered to be an allelopathic crop species, producing phytotoxins such as the lipid benzoquinone sorgoleone, which likely accounts for many of the allelopathic properties of Sorghum spp. Current evidence suggests that sorgoleone biosynthesis occurs exclusively in root hair cells and involves the production of an alkylresorcinolic intermediate (5-[(Z,Z)-8',11',14'-pentadecatrienyl]resorcinol) derived from an unusual 16:3D9,12,15 fatty acyl-CoA starter unit. This led to the suggestion of the involvement of one or more alkylresorcinol synthases (ARSs), type III polyketide synthases (PKSs) that produce 5-alkylresorcinols using medium to long-chain fatty acyl-CoA starter units via iterative condensations with malonyl-CoA. In an effort …

"In Memory Of W. B. Yeats": Elegy For A Man And An Ideal, Travis Mcdonald

English

Travis McDonald: “‘In Memory of W. B. Yeats’: Elegy for a Man and an Ideal” W. H. Auden’s 1939 elegy for W. B. Yeats recognizes the passing of his contemporary as well his own belief in the social efficacy of poetry. The form of the elegy serves the traditional commemorative purpose while simultaneously enabling Auden to critique both Yeats and politically intentioned art.
