Electron Capture By Multiply Charged Ions From Molecular Targets, Justin Harris

Masters Theses

State-selective differential cross sections for single-electron capture processes in collisions of Ne^q+ (q=2, 3, 5) ions with H₂O and CO₂ have been studied experimentally at laboratory collisions energies between 45 and 250 eV, and at scattering angles between 0^o and 7:20^o by means of translational energy-gain spectroscopy technique. The translational energy spectra show that only a few final states are populated depending on the projectile's charge state, laboratory scattering angle, and the collision energy. In addition, these measurements show that the dominant reaction channels are due to non-dissociative electron capture into excited states of …

Design Of Hardware Accelerator For Fuzzy Automata Using Dynamic Partial Reconfiguration, Chinh K. Nguyen

Masters Theses

As embedded systems have become more complex and designers are required to develop new products faster while using fewer chips. FPGAs are a good choice because they offer flexibility to design on-chip devices as well as the embedded systems that are reprogrammable and reconfigurable. Today's tougher cost, higher performance, and lower power consumption requirements demand even more efficient design strategies. Dynamic partial reconfiguration (PR) is a good approach to meet these requirements because it extends the inherent flexibility of the FPGA by allowing partial regions of the FPGA to be dynamically reconfigured with new functionality while other applications are still …

Simulation Of An Intake Manifold Pre-Heater For Cold Diesel Engine Startup, Patrick K. Kreun

Masters Theses

Ensuring consistent, reliable diesel engine startups in cold temperatures is of utmost importance in a number of applications. Under extreme temperatures, the use of glow plugs is complemented by intake manifold heaters. In these, the energy released from combustion increases the intake air temperature before the air enters the main combustion chamber. Since the process also alters the stoichiometry of the fuel-air mixture at the intake ports, the preheater operation must be optimized in order to guarantee successful and reliable in-cylinder combustion during engine startups. This paper describes the development of an intake manifold model incorporating an air pre-heater for …

A Textbook Analysis: A Case Study Of Changes In History Textbooks Based On The Revolutionary War, Danielle Renee Wager

Masters Theses

Research has provided us with information that textbooks are not free from bias. Textbooks are subject to a variety of influences such as the background, beliefs and motivations of the authors of primary sources, secondary sources, and analyses of sources. They are also subject to influences by large consumer groups as well as political and interest groups who finance the textbook market. Due to these influences, it is important for teachers to understand that textbooks are not free from bias, and if they do not do so already, they should supplement their students’ learning with primary and secondary sources beyond …

A Professorial Nation: The Pedagogical Gardens Of William Crimsworth, Jane Eyre, And Lucy Snowe, Elise Green

Masters Theses

Charlotte Brontë was not an intentional pedagogue, but nevertheless, her works reflect the dynamics of an educational ideology that depends on the natural environment. In Brontë's works, including The Professor, Jane Eyre, and Villette, safe learning environments are most commonly found in gardens, providing spaces--literally and metaphorically--dedicated to individual growth. These spaces are not isolated, however, as they are located in bustling towns such as Villette and schoolyards like those of Jane Eyre. Likewise, the individual does not grow in isolation; rather, development is a process that is fostered by an individual's interaction with his or her environment. In essence, …

"You'll Have To Take It: Urban Vigilantism And American Film, 1967-1985", Joseph E. Roskos

Masters Theses

My thesis shows how vigilantism as expressed through the politics of race interacted from the late 1960s until the mid-1980s, serving to support a culture of backlash that drew from the public’s mistrust of government institutions and authorities, and its reactions to crime, class conflict, and racial tensions. Vigilante films served as the battleground where class conflicts were played out; violent backlash was realized; historical wars were refought; cultures and principles clashed; and people cleansed their communities of crime and illegal drug-use. The culture of backlash as portrayed in vigilante films as well as historical events showed how their relationship …
