Cannibalism In A Cultural Context: Cartographic Imagery And Iconography Of The New World Indigenous Peoples During The Age Of Discovery, Cynthia Ann Chambers

History Dissertations - Archive

This dissertation seeks to explore the imagery of the indigenous peoples as cannibals on the fifteenth-century cartography of the New World. This imagery represented the Amerindians of the South American interior on maps and in the minds of Europeans who relied on accounts and illustrations to inform them about the New World. The geographic specificity of cannibal imagery on New World cartography reflected the accounts by voyagers who returned from their transatlantic journey. While many of the cartographers never left the European countries of their origin, their work often encompassed both the littoral boundaries and the cultural differences that defined …

Fabrication, Characterization And Hall Mobility Analysis Of Mos Devices With Low-K And High-K Dielectric Materials, Rakshit Agrawal

Electrical Engineering Theses - Archive

Scaling of MOSFETS has led to leakage current problems in SiO2 dielectric based MOSFETS. This has led to the introduction of high-k dielectric materials which can afford greater physical thickness and achieve the same capacitance with lesser equivalent oxide thickness. But the high-k devices have certain limitations like channel mobility degradation. Mobility degradation in high-k MISFETS is discussed in this work using Hall measurements. The MOS devices were fabricated with SiO2 and HfSiO, on p-type silicon substrate. The fabrication process flow used for both type of MOS devices is explained. Characterization and analysis was performed for the determination of various …

An Acoustic, Historical, And Developmental Analysis Of Sarikol Tajik Diphthongs, Pamela S. Arlund Dec 2006

An Acoustic, Historical, And Developmental Analysis Of Sarikol Tajik Diphthongs, Pamela S. Arlund

Linguistics & TESOL Dissertations - Archive

Sarikol Tajik has been reported to be an unusual language, containing up to twelve diphthongs and being the only language in the Gorno-Badakhshan family to not contain a short and long vowel distinction among monophthongs. However, the basis of such claims is not clear and could be accounted for by any of several factors. For example, different researchers have utilized different definitions of diphthongs, some researchers have (perhaps unknowingly) studied different dialects at different times, while others simply failed to account for the variation that is often found in languages in change. This dissertation reevaluates these claims and the potential …

Does An Exotic Invasive Grass Facilitate The Invasion Of A Woody Species Into Remnant Prairies?: A Study Of The Native, Prosopis Glandulosa And The Alien, Sorghum Halapense, Amie E. Treuer

Biology Theses - Archive

The native tree, Prosopis glandulosa, and the exotic grass, Sorghum halepense, have been invading native prairies in the Southwest U.S. since the 1800s. My objectives were to determine if S. halepense was driving shifts in the abiotic and biotic structure of a native prairie and in doing so facilitating the invasion of P. glandulosa. Both field and greenhouse experiments were established to address these objectives. The presence of S. halepense lowered light and increased soil N in the field relative to the native prairie. Plant species diversity and the number of woody species were higher in an invaded zone than …

Branch-And-Cut-And-Price Methods For Logistics Problems With Limited Risk, Hee-Su Hwang Dec 2006

Branch-And-Cut-And-Price Methods For Logistics Problems With Limited Risk, Hee-Su Hwang

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

There exist many uncertainties in a logistics system, such as unknown demand, unsteady fuel cost, machine breakdowns, and accidents to name a few. Logistics management is difficult because logistics managers must solve a global optimization problem, which includes eliminating as much uncertainty as possible, finding effective methods of managing uncertainty, and operating the entire logistics system effectively. To cope with uncertainty, many efforts have been made for vehicle routing problems. On the contrary, traditional ship-scheduling models ignore uncertainty, even in highly volatile markets. We present a set-packing model that limits risk using a quadratic variance constraint. After generating first-order linear …

Holographic Patterning Of Polymer Dispersed Liquid Crystal Materials For Diffractive Optical Elements, Robert Allan Ramsey Dec 2006

Holographic Patterning Of Polymer Dispersed Liquid Crystal Materials For Diffractive Optical Elements, Robert Allan Ramsey

Physics Dissertations - Archive

Liquid crystals are a soft condensed matter phase that share properties with both isotropic liquids and crystalline solids. Composite materials formed from both low molecular weight liquid crystals and polymers are of both fundamental and technological importance. One method for preparing dispersions of polymers and liquid crystals is polymerization-induced phase separation. Photo-polymerization induced phase separation utilizes a mixture of a liquid crystal and a photo curable polymer contained between two indium tin-oxide (ITO) coated glass substrates. Irradiation of the homogeneous pre-polymer mixture initiates polymerization, which in turn induces a phase separation between the polymer and liquid crystal. Holographically patterned polymer …

Faint X‐Ray Structure In The Crab Pulsar Wind Nebula, F. D. Seward, W. H. Tucker, R. A. Fesen Dec 2006

Faint X‐Ray Structure In The Crab Pulsar Wind Nebula, F. D. Seward, W. H. Tucker, R. A. Fesen

Dartmouth Scholarship

We report on a Chandra observation of the Crab Nebula that gives the first clear view of the faint boundary of the Crab's X-ray-emitting pulsar wind nebula. There is structure in all directions. Fingers, loops, bays, and the south pulsar jet all indicate that either filamentary material or the magnetic field is controlling the relativistic electrons. In general, spectra soften as distance from the pulsar increases but do not change rapidly along linear features. This is particularly true for the pulsar jet. The termination of the jet is abrupt; the east side is close to an [O III] optical filament, …
