Numerical investigation of wire coil heat transfer augmentation
Get PDFThe enhancement of turbulance through the use of turbulators has been studied extensively in the past. The copper coil insert has been tested via experimental research which presented data sufficient enough to conclude that such turbulators would be effective when used in all high-heat load/flux components at the Advanced Photon Source at Argonne National Laboratory. The present investigation discusses the numerical simulation of the wire coil insert using spectral element analysis. The non-dimensionalized heat transfer coefficient, Nusselt Number, and eddy diffusivity are used to draw conclusions regarding main transport mechanisms and optimal design parameters of the wire. The optimal parameter case, as determined by Collins et al. is analyzed here. This analysis confirms the conclusion of previous experimental research, shows that the increase of heat transfer due to the turbulators is not highly correlated to material choice of the turbulator, and maintains that the main heat transfer mechanism is turbulent mixing.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Anne Goering, accepted the attached license on 2016-04-26 at 11:44.The student, Anne Goering, submitted this Thesis for approval on 2016-04-26 at 11:51.This Thesis was approved for publication on 2016-04-27 at 14:14.DSpace SAF Submission Ingestion Package generated from Vireo submission #9505 on 2016-07-07 at 13:50:57Made available in DSpace on 2016-07-07T20:35:19Z (GMT).

How the Nuremberg Trials Set Precedence for Future War Crimes Tribunals to be Conducted: Comparing Reichsmarschall Hermann Goering and Former President of Serbia Slobodan Milosevic
No full textabstract: The purpose of this thesis is to establish how the Nuremberg trials set precedence for future war crime tribunals like the ICTY (the first tribunal since Nuremberg). An analyses of Hermann Goering is given in order to illustrate how his case, from its arguments and indictments to the structure of the court, is similar to Slobodan Milosevic's. These two are the most likely candidates to compare to due to their high ranking position in the political structure of their regime as well as having remarkable similarities to the conditions of their trail by the two tribunal
Decision support for Wisconsin's manure spreaders: Development of a real-time Runoff Risk Advisory Forecast
No full textThe Runoff Risk Advisory Forecast (RRAF) provides Wisconsin's farmers with an innovative decision support tool which communicates the threat of undesirable conditions for manure and nutrient spreading for up to 10 days in advance. The RRAF is a pioneering example of applying the National Weather Service's hydrologic forecasting abilities towards the Nation's water quality challenges. Relying on the North Central River Forecast Center's (NCRFC) operational Snow17 and Sacramento Soil Moisture Accounting Models, runoff risk is predicted for 216 modeled watersheds in Wisconsin. The RRAF is the first-of-its-kind real-time forecast tool to incorporate 5-days of future precipitation as well as 10-days of forecast temperatures to generate runoff risk guidance. The forecast product is updated three times daily and hosted on the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP) website. Developed with inter-agency collaboration, the RRAF model was validated against both edge-of-field observed runoff as well as small USGS gauged basin response. This analysis indicated promising results with a Bias Score of 0.93 and a False Alarm Ratio (FAR) of only 0.34 after applying a threshold method. Although the threshold process did dampen the Probability of Detection (POD) from 0.71 to 0.53, it was found that the magnitude of the events categorized as hits was 10-times larger than those classified as misses. The encouraging results from this first generation tool are aiding State of Wisconsin officials in increasing awareness of risky runoff conditions to help minimize contaminated agriculture runoff from entering the State's water bodies

Computer control of engine-transmission system for improving fuel economy
No full textA control strategy for improving tractor operating efficiency was proposed in this study. The strategy is to control an engine and a continuously variable transmission (CVT) in such a way that the engine works along a line of minimum brake specific fuel consumption (BSFC).Analysis and computer simulation indicated that an engine-CVT system can operate stably and track the desired minimum BSFC curve. Fuel savings of over 25% can be achieved with the proposed control strategy, as compared to a conventional tractor. Design of the control for the engine-CVT system can be achieved by designing engine speed control and CVT ratio control independently, provided the controllers are integrated through the minimum BSFC curve. The engine-CVT system can be viewed as an augmented engine, to which a conventional power train can be added to provide a range of ground speeds. The engine-CVT system can be interpreted as an adaptive control system with the CVT ratio being updated continuously to compensate for load variations.A diesel engine was coupled to a V-belt CVT in the laboratory to validate the proposed control strategy. Test results, indeed, supported the analysis and simulation experiments. Compared to governor-controlled engines on farm tractors, fuel savings of over 15% was achieved with the prototype system, and fuel savings of over 25% could be gained with improved hardware.Made available in DSpace on 2011-05-07T13:50:58Z (GMT).

Google in China : examining hegemonic identification strategies in organizational rhetoric
No full textIndiana University-Purdue University Indianapolis (IUPUI)The author employs Hoffman and Ford’s method for analyzing organizational rhetoric to examine the discourse of Google, Inc. Employing a hybrid method, built on rhetorical criticism which incorporates elements of organizational communication theory, the analysis examines identity rhetoric present in Google’s discourse regarding its operations in China. Using this approach, the author leverages the method to critically examine hegemonic aspects of the discourse in order to examine how Google constructs its Western consumer based audience regarding online privacy and free speech
From Learning to Love: Schools, Pastoral Care and Canon Law in the Middle Ages. Essays in Honour of Joseph W. Goering
No full textR. James Long is a contributing author, The Plurality of Platonic Forms and Trinitarian Simplicity: A Conundrum and its Resolution by the Early Oxford Masters.
Book description: The essays in this volume show how the teaching of law and theology in the medieval schools was part of a pastoral project to foster a just Christian society and to lead souls to contemplation of God. With subjects ranging from scholastic debates about divine simplicity to disputes between parishioners over their reputations, these studies take us across Europe, from the eleventh to the fifteenth centuries, although the heart of the volume covers England and northern France in the decades around 1200. The collection reveals a culture with many threads of mutual influence connecting the learning of the schools, the administration of the Church, the perspectives of professionals in law and theology, and the stories, practices, and devotion of the laity. The first section of the volume considers medieval masters and examines both their subjects of intellectual inquiry and their pedagogical methods, as reflected in the particular textual and manuscript practices developed in the schools. The second section considers how clerics applied learning acquired in the schools in their roles as pastors, judges, and administrators. The final section gathers essays on those aspects of religious culture manifested in popular piety, liturgy, and hagiography. Diverse in methods and scope, these essays nevertheless share a common aim: to honour the remarkable scholarly achievement of Joseph Ward Goering. Although best known for his work on scholastic theology and pastoralia, his interests have ranged from hagiography to visual culture, and this volume reflects the interdisciplinary breadth and coherence of his work. This book presents original studies from many fields, including history, law, language and literature, theology, philosophy, and musicology, along with some editions of hitherto unpublished texts, as a tribute to Joe’s role as a beloved mentor to medievalists from many disciplines.https://digitalcommons.fairfield.edu/philosophy-books/1039/thumbnail.jp

DURABILITY CHOICE AND THE PIRACY FOR PROFIT OF GOODS
No full textWe explore the impact of durable goods piracy in a simple two-period durability choice setting where an originator faces a future for-profit pirate that clones or duplicates copies of the durable good. We find that a social planner, as well as a monopoly originator, may well engage in a sort of 'reversed planned obsolescence'. In other words, they manufacture a product that is more durable than the first-best cost-minimizing level, if they cannot directly control the pirate. We show this occurs even in rental or committed sales settings, indicating Swan's market independence result does not hold here. Copyright � 2009 The Author.
