Bremer, Rose MaryScreening gender and sexuality in contemporary Quebec film adaptation
Doctor of Philosophy, The Ohio State University, 2004, French and Italian
My dissertation examines the relationship between film adaptation, gender and sexuality in contemporary Quebec cinema. Using Robert Stams work as a point of departure, I examine four adaptations directed by well-known Quebec filmmakers: Les fous de Bassan (Yves Simoneau, 1986), La demoiselle sauvage (Lea Pool, 1991), A corps perdu (Lea Pool, 1988), and Le sexe des etoiles (Paule Baillargeon, 1993). Very little has been written to date on the role of film adaptation in the evolution of Quebec cinema. More often than not, whether in Quebec or elsewhere in the Western world, the study of film and literature has been limited to an examination of the relationship between an individual film and its source text. Stam suggests that film adaptation be looked at as a special kind of intertextual relationship between a hypotext (a source text) and a hypertext (its film adaptation). The concept of intertextuality situates literature and film as part of a complex matrix of discursive practices that underlies all texts produced by a culture, facilitating the analysis of film adaptation and the representation therein as specific to Quebec. Through the course of this study, I situate each of the four films noted above with respect to the sociocultural and economic milieux of production and examine their popular and critical reception. In addition, I provide background on each of the filmmakers as well as on the authors of the pertinent source texts in order to situate the adaptations within Quebec’s literary and cinematic narrative traditions. Furthermore, as Simoneau, Pool and Baillargeon are known for their controversial and innovative representations of gender and sexuality, I examine this aspect of each of these adaptations in-depth.

TOKEKAR, DEVKINANDAN MADHUKARMODELING AND SIMULATION OF REACTING FLOWS IN LEAN-PREMIXED SWIRL-STABLIZED GAS TURBINE COMBUSTOR
MS, University of Cincinnati, 2006, Engineering : Mechanical Engineering
Combustion in a lean pre-mixed (LPM) combustor may become unstable due to small changes in geometry and the manner in which reactants are introduced. This may lead to excessive thermal loads and possible off-design operation. A comprehensive understanding of combustion instability is therefore needed. The present study aims to analyze the flow and flame dynamics in a model LPM gas turbine combustor in LPM combustion. Fluent is used as the flow solver for the present study. The 3-D Navier-Stokes equations are solved along with finite-rate chemical reaction equations and variable thermo-physical properties. Large-eddy-simulation (LES) technique is used to model turbulence. The dynamic version of the Smagorinsky-Lilly model is employed to describe subgrid-scale turbulent motions and their effect on large-scale structures. At first a non-reactive LES was performed in model round and LM6000 combustor. The results for time averaged mean velocity are compared with the previous LES work by Grinstein et al. and Kim et al. Using non-reacting case for LM6000, reactive simulation was initiated, with lean methane-air mixture with equivalence ratio 0.56. Species transport equation is solved for global methane-air two-step reaction with six volumetric species to predict the local mass fraction of each species. The reaction rates that appear as source terms in the species transport equation are computed using finite-rate/eddy-dissipation model, which computes both, the Arrhenius rate and the mixing rate and uses the smaller of the two. It is observed that as the flow enters the chamber, it bifurcates in two shear layers forming a prong like structure. The layers further tend to reattach to the wall at a distance approximately equal to 3D. Counter-clockwise recirculation zones are formed in the corners, whereas clock-wise toroidal vortex structure is formed in the center. The flame is located in between these vortex structures and thus experiences shear-layer instabilities. It is also noticed that the eddy structure in case of reacting case is thicker than that of the non-reacting case. This is mainly due to the temperature dependent viscosity, which has a stabilizing effect on the flow.

Shomo, Michael F.An Aesthetic of Eccentricity: A Narrative Analysis of Two Early Berlioz Overtures
Master of Music (MM), Ohio University, 2015, Music History and Literature (Fine Arts)
The peculiar style of Hector Berlioz has been scrutinized by generations of music critics and described by contemporary music scholar Stephen Rodgers as an aesthetic of eccentricity. Yet broad aspects of the eccentricities inherent to Berlioz’s approach have received little analysis, resulting in an incomplete understanding of the role these irregularities play within his overall style. Recent theoretical developments in the area of narratology within musical analysis have provided the analytical tools necessary to uncover and explain details of Berlioz’s aesthetic of eccentricity that have been left undefined. The following thesis summarizes the findings of a narrative analysis of Les Francs-Juges Overture and Le Roi Lear Overture while showing how the peculiar aspects of Berlioz’s style, and the narrative interpretation of his music, are essential to understanding his legacy within the era of Romantic music. The musical examples cited within this thesis have been transcribed from Hector Berlioz: New Edition of the Complete Works, Volume 4 and Volume 20. This author has titled each musical example based on its context within the narrative analysis.

Kartuzova, Olga ValeryevnaA computational study for the utilization of jet pulsations in gas turbine film cooling and flow control
Doctor of Engineering, Cleveland State University, 2010, Fenn College of Engineering

Jets have been utilized in various turbomachinery applications in order to improve gas turbines performance. Jet pulsation is a promising technique because of the reduction in the amount of air removed from compressor, which helps to increase turbine efficiency. In this work two areas of pulsed jets applications were investigated, first one is film cooling of High Pressure Turbine (HPT) blades and second one is flow separation control over Low Pressure Turbine (LPT) airfoil using Vortex Generator Jets (VGJ)

The inlet temperature to the HPT significantly affects the performance of the gas turbine. Film cooling is one of the most efficient methods for cooling turbine blades. This technique is simply employing cool air discharged from rows of holes into the hot stream. Using pulsed jets for film cooling purposes can help to improve the effectiveness and thus allow higher turbine inlet temperature without affecting the blade's life. Engine cost will thus be reduced by providing the same capacity from smaller, lighter engines. Fuel consumption will be lowered, resulting in lower fuel cost. Effects of the film hole geometry, blowing ratio and density ratio of the jet, pulsation frequency and duty cycle of blowing on the film cooling effectiveness were investigated in the present work.

As for the low-pressure turbine (LPT) stages, the boundary layer separation on the suction side of airfoils can occur due to strong adverse pressure gradients. The problem is exacerbated as airfoil loading is increased. If the boundary layer separates, the lift from the airfoil decreases and the aerodynamic loss increases, resulting in a drop in an overall engine efficiency. A significant increase in efficiency could be achieved if separation could be prevented, or minimized. Active flow control could provide a means for minimizing separation under conditions where it is most severe (low Re), without causing additional losses under other conditions (high Re). Minimizing separation will allow improved designs with fewer stages and fewer airfoils per stage to generate the same power. The effects of the jet geometry, blowing ratio, density ratio, pulsation frequency and duty cycle on the size of the separated region were examined in this work. The results from Reynolds Averaged Navier-Stokes and Large Eddy Simulation computational approaches were compared with the experimental data.

Mohan, Arvind ThanamLarge Eddy Simulation of Separated Flows
Master of Science, The Ohio State University, 2013, Aero/Astro Engineering
In the past few decades, Large eddy simulation has seen a surge in interest from the CFD community owing to its inherent advantages in terms of accuracy compared to RANS methods. Advances in computing power and memory capacity has now made it possible to use LES frequently, atleast at the academic level. The focus of the present work is to simulate a standard test case featuring ow separation, re- circulation, reattachment and observe how LES performs in comparison to RANS, since separated turbulent ow is one of the most challenging cases for any turbu- lence solver, especially for wall bounded ows. The major thrust of the work will be to implement a Dynamic Smagorinsky Subgrid Model proposed by Lilly (1992) in OpenFOAM and compare its accuracy with the standard Smagorinsky-Lilly model for the same case. Additionally, a considerable amount statistical analysis has been performed to better understand physical ow features from a statistical viewpoint and corroborate the results.

Kenny, William TThe Development and Application of the Hi-Resolution VOC Atmospheric Chemistry in Canopies Model
Doctor of Philosophy, The Ohio State University, 2015, Environmental Science
Volatile organic compounds (VOC) and their reaction products are ubiquitous in earth’s atmosphere and play many important roles leading to implications in climate change as well as public health. The many significant consequences of VOCs and their reaction products merit considerable study. However, understanding of the emissions, chemistry reaction pathways and dispersion of many VOCs is very limited due to the short lifetimes of many of them, as well as complex, nonlinear environmental and chemical phenomena, such as light dependence, turbulence, and temperature, which can impact their emission, reaction and movement. Current data is limited due to the difficulty and expense inherent in robust observation campaigns to collect data on emission, concentration and fluxes of VOCs, and few models have included very many high-resolution processes that can affect VOCs. We have developed the Hi-Resolution VOC Atmospheric Chemistry in Canopies (Hi-VACC) model to study the emission, chemistry and dispersion of BVOC at a very high spatial resolution (on the order of 1m3) and fast time scale. We have developed the model to get the necessary meteorological and atmospheric variables from the output of a previously run large eddy simulation (LES) model, and have adapted emissions and chemistry modules to handle all processes. As a result, Hi-VACC can incorporate the effects of real canopy structure, light attenuation, high-resolution turbulence, horizontal and vertical heterogeneity, and complex VOC emission schemes in modeling the emission, chemistry and dispersion of VOCs. We have used Hi-VACC to investigate the impact of vegetation-induced turbulence around small lakes on the interpretation of flux measurements of emissions from small lakes; and to determine good locations for measurement tower placement in such lakes to minimize these effects which skew measurements. We have also used Hi-VACC to investigate the sensitivity of glyoxal and isoprene flux from forest canopies to heterogeneity in canopy structure and source distribution, finding heterogeneity in either able to substantially alter the resulting fluxes from the forest canopy. Given the high resolution capabilities of Hi-VACC, it is a tool that is uniquely beneficial for gaining insight into the complex processes that govern VOCs which is necessary for understanding their impact. In the studies presented here we demonstrate Hi-VACC’s usefulness as a tool for informing measurement campaigns in areas where canopy structure or topography may impact the dispersion and fluxes of VOCs or other scalars, as well as Hi-VACC’s potential usefulness in informing the parameterization of lower-resolution models which may fail to take into account high-resolution processes that will have an effect on the ultimate concentrations of VOCs, which could be skewed in such models. Combining results from Hi-VACC with informing new measurement campaigns of VOCs and using it to help improve models for VOC emissions estimates and regional air quality modeling has the potential to greatly improve our overall understanding of VOCs and their impact on our environment.

Whiteman, Jacob TActive Flow Control Schemes for Bluff Body Drag Reduction
Master of Science, The Ohio State University, 2016, Aero/Astro Engineering
Bluff body vehicle drag is dominated by pressure drag on the rear end of the body due to the effect of momentum causing the flow to detach from the body contour. This flow separation results in a pressure difference between the front and back end, making up the pressure drag. A friction force is also generated at the contact of air and solid body that contributes to the total drag, however in the case of bluff body flow this value is far outweighed by the pressure drag. The rear separation region is also dominated by complex time dependent vortices, of which this pressure drag is also dependent, thereby making the overall drag at least partially dependent on the strength and frequency of this shedding phenomena as well. In this study, both a two-dimensional and three-dimensional Ahmed model are used, however only the zero-slant angle case is studied to coincide with the majority of transportation trucks and buses that are on the road today. Numerical simulation experiments on vortex shedding and corresponding drag coefficients from a two-dimensional bluff body are performed over a range of Reynolds numbers from one to four million. The simulations are performed using ANSYS Fluent, specifically the turbulence model of k-epsilon RNG (Re-normalization Group). In order to enhance the accuracy of the shedding wake vortices, an enhanced non-equilibrium wall treatment is utilized. Active control is implemented on the body via velocity boundary conditions in the form of blowing and suction jets. These controls range in velocity from half to double the free-stream inlet velocity. An overall drag coefficient reduction in excess of 75\% is observed for maximum power input to the actuators. In addition, a trend of increasing Strouhal number for each successive increase in actuator power (and corresponding reduction in drag) is noted. Important physical mechanisms involving near-body wake flow are analyzed to determine optimal wake flow pattern and corresponding control schemes. Discoveries are then used to study similar controls on the three-dimensional bluff body based on those of the two-dimensional model. For the 3-D simulations the Large Eddy Simulation model is used for the calculation of flow field variables within Fluent, however an introductory RANS analysis is performed as well. Control schemes involving suction jets are investigated. Aspects of the flow pattern such as shedding and streamlines are studied in depth in an effort to determine the most efficient application of the suction controls. These schemes seek to reduce the aerodynamic drag without constraints on the basic design of the model itself. An average of 10\% drag reduction is recorded.

Rahimi, AbbasDirect Numerical and Large Eddy Simulation of Stratified Turbulent Flows
Doctor of Philosophy, University of Akron, 2015, Engineering
Oceanic and atmospheric flows have very large length and time scales, they also undergo intense vertical stratification with the consequence that the horizontal motions have larger scales compared to vertical motions. These effects make the simulation of geophysical flows very difficult, more challenging, and quite different from the simulation of manufacturing flows. Thanks to recent progress in computational technology, as well as, scientific availability of super computers, researchers can investigate some fundamental characteristics of these flows using direct numerical simulation (DNS) for relatively low Reynolds numbers $Re$. However, natural stratified turbulent flows represent very high turbulent intensity i.e. ${Re}\sim 10^6-10^8$ in geophysical flows, and $Re\sim 10^{10}-10^{12}$ in astrophysical flows. Therefore, with current computation limitations, it may take years to carry out simulation of these flows for very few eddies turn over time. To defeat this issue, researchers are inclined to apply large eddy simulation (LES) to resolve large energetic scales of motion and model subgrid scales of motion statistically. First, a code was developed to numerically solve Navier Stokes (NS) and scalar transport equations using pseudo-spectral method in a triple periodic box, and the code has been validated with the previously relevant DNS of weakly to strongly stratified decaying homogeneous turbulence. Also, numerous useful quantities, which help to describe these types of flows, are derived and discussed. Next, well-known subgrid-scale (SGS) turbulence models for large eddy simulations (LES), in presence of helical and non-helical stratified turbulent flows, are quantitatively assessed. Lastly, three new models based on the hybridization of concepts behind the SGS models, and the modified time scaling of Smagorinsky model for stratified turbulent flows has been proposed and tested. The new models show improvement in prediction of anistropy in turbulence which is initiated due to stratification.

Tickel, JamesTemporal Brush Strokes: Aspects of Temporality and Musical Narrative in Grisey’s Partiels and Talea
Master of Arts, The Ohio State University, 2017, Music
Music can be observed as the construction of sound and silence throughout time. We have a vast vocabulary and many analytical tools to talk about the construction of music outside of time, but still, struggle to find ways to discuss music in terms of temporal relationships. Composers often use terms such as `pacing’ and `flow’ to describe temporal relationships in music. This thesis will attempt to address temporality and musical narrative in a more rigorous fashion, building on concepts from the literature of music perception and the author’s own observations. The methodologies presented in this paper will be illustrated through analysis of two works, Partiels and Talea, of Gerard Grisey, a founder of the musical style known as `spectral music’, one of the more pervasive styles of the later-twentieth and twenty-first centuries. Due to its nature, spectral music often avoids common tendencies of musical construction regarding melodic and motivic development and transformation. Rather, harmony and timbre are the tools composers look to for musical direction, and this paper intends to explore how composers shape these timbral and harmonic resources through time to create a sense of musical narrative. While the methodologies presented in this thesis are focused primarily on spectral music, the author feels that they can be applied, in a general sense, to musics of many other styles and genres.

Sengupta, SoumyoInvestigation of Flow Dynamics of a Subsonic Circular to Rectangular Jet
Master of Science, The Ohio State University, 2016, Mechanical Engineering
Large Eddy Simulation based investigation is performed on a circular to rectangular Mach 0.226 jet to understand the effect of the non-axisymmetric geometry on the jet flow dynamics. The nozzle has a circular cross-section at the inlet and a 2:1 aspect ratio rectangular cross-section at the exit. The Reynolds number of the flow is 73,242 and the nozzle has an equivalent diameter of 0.054 meters. Comparison with experiments, indicate a good match of the normalized mean and rms velocities along the jet centerline. Q-criterion iso-levels confirm the existence of large hairpin like vortices, which initially are dominant along the major axis but further downstream appear along the minor axis as well. To highlight the influence of different frequency ranges, the velocity field at the core collapse location is first decomposed using Empirical Mode Decomposition (EMD). The spectrum in these different ranges is then correlated with observations along representative lip-line at the major and minor axes and the corner. The presence of the large scale structures corresponding to low frequency ranges is predominant along the corner compared to major and minor axes. The correlations provide information on the ffect of specific scales at the end of potential core along the streamwise direction. The major components of low frequency structures in the propagated signal occur between St = 0.05 and St = 0.3. The correlation analysis shows that structures formed along the corners and minor axis dominate the large scale dynamics of the flow. The Joint Probability Density Function (JPDF) analysis is used to study flow along major and minor axis of the rectangular jet as well as an equivalent circular nozzle. Variations in entrainment and ejection-like patterns along the minor and major axes of the rectangular jet are quantified. Results with an equivalent circular nozzle are compared which indicate enhanced ejection and entrainment like motions for the rectangular nozzle compared to the equivalent circular nozzle.

Mustafa, MansoorInvestigation into Offset Streams for Jet Noise Reduction
Master of Science, The Ohio State University, 2015, Aero/Astro Engineering
This effort investigates the near field behavior of two ideally-expanded subsonic dual-stream jets. One case implements a traditional symmetric, concentric dual-stream nozzle configuration while the other imposes an asymmetric, eccentric layout to model the behavior of an offset stream. The essence of an offset stream is to force an uneven azimuthal distribution of the secondary coflow and create an outside stream that varies in thickness. Past studies have shown a benefit in acoustic propagation in the direction of the thickest coflow and the present work further analyzes this phenomenon. A LES (Large Eddy Simulation) approach is implemented to run the simulations for both cases and a number of qualitative and quantitative analyses tools are used for post-processing. A reduction in the noise levels for the lower, thicker side of the eccentric nozzle is observed in comparison to the baseline concentric case. Examination of the mean flow behavior shows a shorter, thinner primary potential core for the offset case and a faster axial velocity decay rate. The asymmetric distribution of the coflow causes varying velocity profiles in the radial direction for the top and bottom regions and consequently produces unique flow features on either side. Lower levels of shear stress and slower decay rates lead to less turbulence production on the lower side of the eccentric nozzle. An investigation into the flow structures reveals lower vorticity and weaker convective structures on the bottom which influences propagation in that direction. Two-point correlation analysis reveals the presence of smaller turbulence scales in the lower, thicker portion of the eccentric case. This is further confirmed by an Empirical Mode Decomposition (EMD) study that shows lower frequency ranges dominate the concentric near field in comparison to the eccentric. The combination of these unique features demonstrate the principles behind the acoustic benefit of implementing offset stream flows in dual-stream nozzle configurations.

Brown, Clifford A.Simulation of the Localized Arc Filament Plasma Actuators for Jet Excitation
Doctor of Philosophy, University of Akron, 2010, Mechanical Engineering
The concept of jet control by external forcing is not new. The first published demonstration of a jet responding to outside forces occurred in the mid-1800's. It was not, however, until the 1950's, with the advent of commercial jet aircraft, that scientific study of the subject greatly increased as researchers used external forcing to study the structure and noise sources present in a jet plume. Interest in active jet control continues today, particularly with the additional possibilities afforded by significant advances in measurement and simulation technology, even though it remains limited by the available jet actuators to relatively small, low Reynolds number jets that are of little similarity to the large, highly turbulent jets common in real world applications. However, the recently developed Localized Arc Filament Plasma Actuators (LAFPA) have the potential to expand active jet control research to include these larger, higher Reynolds number jets. The LAFPA have been used successfully to control a small-diameter, high-speed turbulent jet to achieve some plume mixing enhancement and limited noise mitigation. The system, however, must still be extended to a larger class of jets common in the real world and optimized for an application. This work addresses both of these issues First, experiments are conducted to determine the impact of the LAFPA on a large-scale jet. A model of the LAFPA is then developed for use in the future CFD based studies of excited jets. The model performance is investigated using multiple CFD methodologies to determine the optimal combination of actuator model and CFD scheme for excited jet simulations. Ultimately, the model developed will be used by researchers in future simulations to optimize the actuator system for noise reduction, IR signature reduction, or to system scalability for deployment on larger jets in real-world applications.

Schrag, Steven DASHCAN: Nazis, Generals and Bureaucrats as Guests at the Palace Hotel, Mondorf les Bains, Luxembourg, May-August 1945
Doctor of Philosophy, University of Toledo, 2015, History
An Abstract of ASHCAN: Nazis, Generals and Bureaucrats as Guests at the Palace Hotel, Mondorf les Bains, Luxembourg, May- August 1945 by Steven David Schrag Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in History The University of Toledo May 2015 In the closing days of World War II the Allied Armies overran Germany. German government officials and local leaders, all Nazi Party members, left the people remaining in their cities and villages to deal with their new occupiers. The Allies needed to restore services, such as power, and make sure the people could be fed and sheltered. They also needed to round up German prisoners of war and suspected war criminals. Securing prisoners of war did not represent much of a problem, other than the sheer numbers of prisoners. Often, however, the war criminals proved difficult to locate. By the time the war ended on May 8 1945, many suspected war criminals had been captured by the Allies. The Allies started setting up special camps to house these men. One of these camps, named ASHCAN, first began in Spa, Belgium and later changed locations to the Palace Hotel in Mondorf les Bains, Luxembourg. This prison, known officially as Central Continental Prisoner of War Enclosure 32, held high value Nazis officials, government leaders and general staff officers. At this camp the interrogation team collected biographical information as well as information regarding how the Nazi government functioned. After about two months the Shuster Commission, a scholarly panel of men attempting to construct a history of the Third Reich, arrived at the camp, also gathered information. Neither the local interrogators nor the Shuster Commission attempted to gather information implicating any of these men in war crimes, instead focusing more on learning background information about what they did during the war. While a tremendous opportunity presented itself at ASHCAN, the International Military Tribunal did not question these men. Once the International Military Tribunal looked over the interrogations conducted at the camp, they declared the information as useless. In this dissertation, the author investigates ASHCAN to determine the failings of the camp. It describes who the Americans incarcerated at ASCHAN, how they lived, the treatment they received, and the interrogations they received. Further, this dissertation explains why the IMT did not participate more in the camp, and why the camp is, in general, viewed as a failure.

Chibinda, PeterPerec ou la Liberté d'un Bohéme Tentative de Lecture en Dyptique de Quelques Livres de Perec
PhD, University of Cincinnati, 2002, Arts and Sciences : French
In this era of literary theory explosion, literature has been pushed to frontiers never imagined before. While some critics argue that the push has benefited literature others contend, understandably so, that the trend has opened doors to misinterpretation of certain authors based on out of context reading of their works. Without trying to take side, I would simply submit that Perec is one such author who is often times misrepresented. While I absolutely understand the idea that, a book shares certain affinities with any other produced commodity and that therefore the consumer is at liberty to deal with it the way he or she deems satisfactory, we should not loose sight of the fact that the contextual back drop in which any particular work is produced offers as much an interesting reading as any other. This dissertation looks at four different novels by Perec and tries to anchor them, as the author himself begs the reader to do, in their social, political as well as their cultural background. The strategy adopted in this work consist of reading side by side, like the two sides of an open book or matching pieces of a puzzle, two novels from each of the two most influential literary periods on Perec's writing. The dissertation pays particular attention to the fact that some of the author's books seems to sit at the end of each other's spectrum and tries to construe the relevance of that polarity with regard to the author's work current criticism . The study matches in the first instance Les choses against Un homme qui dort two novels with a social agenda, and in the second phase, it pits La disparition against Les revenentes two novels from the author's oulipian experience. The reading model provided in this work attempts to highlight contextualized understanding of Perec's work and to draw challenging observations that could, may be, pave a way to a new reading and understanding of the four selected books. The most engaging remark postulated in this dissertation is the fact that it is believed that Perec is more of "un auteur engagé" (and not, as portrayed by other critics, a mere ludic autobiographical writer) who failed to articulate his philosophical vision, living them strewn all over his body of work because of his inadequate academic background.

Phadke, Nandan NeelkanthOPTIMIZATIONS ON FINITE THREE DIMENSIONAL LARGE EDDY SIMULATIONS
Master of Science, The Ohio State University, 2015, Computer Science and Engineering
Large Eddy Simulation kernels working on 3 dimensional point grids using an Alternate Direction Implicit (ADI) scheme for solvers face the challenge of having a significant portion of the computation access non contiguous data, resulting in decreased performance. We focus on this issue with FDL3DI, an implementation of LES, and suggest potential areas of optimization. We pursue a data layout transformation as a solution to this problem and evaluate its effectiveness. We also identify the coarse grained nature of any parallelism employed in the kernel and attempt to increase performance of the overall kernel by utilizing fine grained parallelism using the many-core architecture of the Intel Xeon Phi accelerator. We develop a hybrid OpenMP+MPI framework for this microkernel and optimize it for Xeon Phi using a variety of techniques. We compare performance characteristics on the Xeon Phi with that on a traditional CPU for a range of optimizations and problem sizes. We evaluate the use of offload mode and quantify the data transfer costs that limit performance and assess the potential for effective use of such accelerators.

Muffitt, Nicole ChristineFrom Contest to Classic; A Review of Trombone Literature from the Paris Conservatoire
BM, Kent State University, 2016, College of the Arts / School of Music
This thesis covers the history of the trombone as used in the Paris Conservatoire, the Contests for Prizes at the same institution, as well as a brief history detailing the changes in compositional style in French art music from the classical era to twentieth century. The Contests for Prizes, or, Les Concours de Prix are competitions held yearly at the conservatoire, where all members performing on the same instrument compete for rankings. Prior to 1999, the winner of this contest would receive a Premier Prix, or first prize, and would thusly graduate from the institution. The latter half of this work involves original research meant to uncover which works from the Contests for Prizes remain relevant in the canon of repertoire played by trombonists in American universities and studios today. The focus of this research is to shed light on the works played today, and explain the qualities of these works that have kept them relevant.

Leroy, Manon Z.Le miroir dans Belle du Seigneur d'Albert Cohen: Une duplicite problematique
Master of Arts, Miami University, 2012, French
Ce memoire vise a analyser l’impact du miroir dans l'oeuvre Belle du Seigneur d’Albert Cohen. L’etude revele que derriere l’apparente inutilite de l’objet au sein des scenes ou il intervient, il est en realite un element macrostructural essentiel. Cette duplicite qui est essence-meme de l’objet est donc analysee ici a plusieurs niveaux et selon differents points de vue: psychanalytique lorsqu’il est pris a part dans des episodes, comme une illustration de la theorie du « stade du miroir » chez Lacan, et narratologique lorsqu’il est considere comme une mise en abyme de la structure. La confrontation de ces « niveaux » du texte revele une duplicite des personnages, des discours, de l’auteur et de l'oeuvre toute entiere qui suspend le sens et le maintient dans un va-et-vient constant, remettant ainsi en question l’hegemonie du narrateur au sein du roman.

Khosravi Rahmani, RaminTHREE-DIMENSIONAL NUMERICAL SIMULATION AND PERFORMANCE STUDY OF AN INDUSTRIAL HELICAL STATIC MIXER
Doctor of Philosophy in Engineering, University of Toledo, 2004, Engineering
In chemical processing industries, heating, cooling and other thermal processing of viscous fluids are an integral part of the unit operations. Consequences of improper mixing include non-reproducible processing conditions and lowered product quality. Static mixers economically promote the mixing of flowing fluid streams. One typical static mixer, the helical static mixer, consists of left- and right-twisting helical elements placed at right angles to each other. The range of Reynolds numbers of practical flows for helical static mixers in industry is usually from very small values to not very large values (e.g., Re = 5,000). This thesis describes how static mixing processes of single-phase Newtonian and also non-Newtonian liquids can be simulated numerically and provides useful information that can be extracted from the simulation results. The Turbulent flow case is solved using the most common Reynolds Averaged Navier-Stocks (RANS) models as well as Large-Eddy Simulation (LES) turbulent flow model. The numerical simulation of the mixing in the helical static mixer has been performed via a two-step procedure. In the first step, the flow velocity (and the pressure) is computed. These values are then used as input to the next step. In the second step the particle trajectory in the flow field is calculated. At the entry of the pipe inlet, a large number of marker particles are uniformly distributed over half of the flow field. This represents a simplified model for diametrical feeding of the mixer with two liquids. Using different measurement tools, such as Residence Time Distribution (RTD) and Particles Distribution Uniformity (PDU), the performance of a six-element helical static mixer is studied. It is shown that the Reynolds number has a major impact on the performance of a static mixer. It is also shown that the performance of a helical static mixer is different for Newtonian and non-Newtonian fluids in non-creeping flows. Finally, heat transfer within a helical static mixer is investigated. The effects of different flow conditions on the performance of the mixer are studied. It is shown that the helical static mixer is more effective for low Reynolds number laminar flows.

Whiting, George H.“JE NE M’OCCUPE PLUS DE ÇA” [I AM NOT CONCERNED WITH THAT ANYMORE]: THE POETIC SILENCE OF ARTHUR RIMBAUD
Master of Arts (MA), Bowling Green State University, 2007, French
Entering young adulthood, the 19th century French poet Arthur Rimbaud permanently abandoned his literary gifts. He never explained why. His enigma is heightened by its polarities: the preeminent poet in zealous pursuit of his art transformed into a man of science and industry, limiting his written expression to flat and stunted phrases. The thesis aimed to explain this phenomenon. The study relied heavily on biographical material and used Rimbaud’s literary works primarily in their autobiographical capacity. Abraham H. Maslow’s classifications of human motivation provided the appropriate psychological context, functioning as touchstones throughout the thesis. Analysis determined that Rimbaud’s psyche gave priority to achieving self-transcendence and poetry needed to function within the path chosen to satisfy this need. His final philosophy of materialism and objectivism proved unforgiving to the subjective ambiguities of art. In addition, he angrily blamed the artistic mindset for years of substance abuse and public scandal.
