An analysis of luminosity classification of red stars using 2MASS photometric data to create an unbiased sample of red dwarf stars

Furiak, Nicolas M. January 2002 (has links)
Study determined if 2MASS photometric data are reliable for luminosity classification using JHK plots of Reid and Hawley (2001). Effects of interstellar reddening on the placement of giant and dwarf data on the JIIK plot were analyzed. Dwarfs (N=54) were selected from Hipparchos and the 2MASS data reduced to an H-K range of 0.14-0.40. A disk dwarf region was identified using linear regression on the low space velocity stars. Giants selected from Volume 5 of the Michigan Catalogue of HD stars and SAG stars classified at Ball State University. They yielded 304 individual giants and 13 matches in the 0.14-0.40 H-K range respectively. The 2MASS data was reliable for luminosity classification of the SAGBSU giants. The classification of the Michigan giants was not possible due to interstellar reddening and the likely presence of faint giant companions. / Department of Physics and Astronomy

Looking towards India: Nativism and Orientalism in the Literature of Wales, 1300-1600

Conley, Kassandra Leighann 04 June 2016 (has links)
After the conquest of 1282, Wales increasingly fell under the dominion of England and in 1535, the first Laws in Wales Act officially annexed the country. During this period of political and legal instability, Welsh men and women fought to regain independence, a struggle that led to the development of a nascent national identity. For many authors, this identity was fundamentally rooted in the topography of Wales and the mythical histories concerning the cultivation of its land. This interest in native mirabilia corresponded with a period of increased availability of English and continental geographical treatises and travelogues that provided Welsh authors with a new vocabulary for discussing wonder. Medieval and early modern Welsh authors incorporated these exotic geographies into their accounts of native landscapes in order to differentiate Wales from England and argue for a sense of Welsh cultural exceptionalism based in its alterity. / Celtic Languages and Literatures

Federal giants and wind energy entrepreneurs: utility-scale windpower in America 1970-1990

Serchuk, Adam 08 November 2006 (has links)
In 1994, the use of wind turbines for electricity generation verges on economic respectability. Two contradictory trends have prepared a fertile niche for utility-scale windpower. The introduction of "deregulatory," competitive principles onto the electric industry fostered a non-utility generating sector relying on unconventional technologies. Simultaneously, policy-makers using "hyper-regulatory" tactics to pursue social goals such as reduced pollution pushed utilities to include renewable energy in their resource· plans. Both tendencies advanced windpower. By comparing the Federal Wind Energy Program (FWEP) to California's entrepreneurial windpower industry, this dissertation argues that windpower constituted a conservative addition to the American electric utility system, rather than a radical challenge to it. True, venture capitalists producing and delivering windpower to the nation's transmission grid challenged the utilities' financial control. But participants in the windpower story have constructed a version of windpower largely compatible with the electric system. The most notable products of the FWEP--multi-megawatt wind generators--proved too complex, too expensive and too unreliable for their environment. Windpower entrepreneurs, by contrast, devised smaller machines better suited to the market. Equally important, regulatory support shielded the windfarms from the political and economic turnabouts that scuttled the ambitious FWEP, which relied completely on ephemeral Federal patronage. Today's wind entrepreneurs present their technology as a cost-effective addition to the conventional generating system, rather than as a social tool dependent on government support for environmentalism. But the story of windpower does not constitute a self-contained drama. In addition to pitched negotiations over wind energy, the story implicates the changing utility industry, shifts in global energy politics, and emergent environmentalism. The windfarms' "success" and the FWEP's "failure" frequently depended on actors' ability to exploit or insulate themselves from events unrelated to windpower itself. Thus, the dissertation binds firstperson accounts from participants in the windpower story to strands of larger histories, recounted through periodical and secondary literature. The dissertation speaks to historians, sociologists, energy managers, policy-makers and members of the community of "science and technology studies." Ultimately, it aims to produce a tool for the actors and policymakers it describes. / Ph. D.
