For more than fifty years, the Independent (indie) Music Scene has existed as an evolving business model, allowing indie artists to develop a wealth of progressive musical ideas while creating a sustainable audience base. American Musical Theatre has an already-established rich history of adapting styles to fit concurrent trends in popular music while maintaining the story as the core of a show. While some indie artists (The Lisps, The Mountain Goats, Stephin Merritt, and Stew) and some musical theatre composers (David Yazbek, Doug Crossley, and Michael Friedman) have created crossover works, there is currently an overall dearth of musical theatre pieces infused with the indie style and a lack of indie albums with an actable musical theatre storyline. The intent of this thesis is to prove that although American Musical Theatre and the Independent Music Scene are two vastly different art forms, they can be combined to create a viable and unique form that appeals to both audiences. The indie-rock monologue ...and then, Claire was composed, recorded, and performed to test the viability of this thesis. In addition to presenting research on the history of American Musical Theatre and the Independent Music Scene, an analysis of the already-successful artists mentioned above is presented to provide context for ...and then, Claire. This context along with the original indie-rock monologue proves successful combinations of American Musical Theatre and the Independent Music Scene as well as the potential for more attempts in the future.

The thesis deals with life and work of bishop,later cardinal Frantisek Tomask in the 50´s and 60´s of the twentieth century. The work particularly focuses on the extremely interesting and moving period,when Frantisek Tomasek worked as a priest and religion teacher (scripture) in Moravian village of Moravska Uzova.The thesis involves both copies of authentic documenst from the Archives of Opava and also testimonies of his former pupils and parishioners, giving supporting evidence of many activities of Mr. Tomasek at that time. The first part of the work brings a detailed description of the state of the then Catholic Church on the background of complicated and hard political situation in former Czechoslovakia in the 50´s and 60´s. The other part focuses on eleven years of life and work of Frantisek TOmasek in Moravska Uzova, especially on his religious and pedagogical activities. The evidence of a very successful and human work of this unique man can be found both in this part of work and also in the enclosure - in the form of re-told testimonies of his former pupils.

Due to the complexity of the process, in addition to significant energy input, air separation units (ASUs) also have high degrees of material and thermal integration and low process agility. As markets become more competitive and dynamic, especially after electricity market deregulation, ASUs can no longer practice mostly stationary operations, and are in need for design and control strategies to achieve high adaptability. In this study, we address such issues through a dynamic optimization framework. The use of rigorous dynamic models is important for developing economically beneficial designs and operating practices. The first part of this study focuses on the modeling aspect. For the column section of the plant, a full-order stage-wise model and a collocation based reduced order model are proposed. Model size, simulation time and predication accuracy are compared. For the primary heat exchanger, a novel moving boundary model is derived to handle the phase change in such a multi-stream heat exchanger. Simulation results demonstrate the capability of the proposed model in tracking the boundary points of the phase change occurrence, as well as the potential pinch point, along the length of the heat exchanger. The second part of the study addresses the operation aspects of ASUs through conducting dynamic optimization studies with collocation based dynamic models. We first performed a comprehensive analysis for a storage-then-utilization strategy on a nitrogen plant, following a two-tier multi-period formulation. As the parameter varies with time, the plant collects liquid, either directly from liquid product or by liquefaction of overproduced gas product, and then redistributes it for meeting gas product demand or as additional reflux. Effects of electricity price and demand profiles, additional operation costs, as well as product specifications are explored. Then we investigated the economic incentive for employing preemptive actions on a super-staged argon system, which allows the plant to take actions before external changes arrive. In the evaluation, changes are in the gas oxygen product demand. During the preemptive period, the plant takes either a single set or multiple sets of control actions. In the demand increase case, operation degrees of freedom are introduced to or removed from the set of decision variables. The demand decrease scenarios are explored with an under-supplied or saturated liquid oxygen market. / Dissertation / Doctor of Philosophy (PhD)
