Analysis and Simulation of a Batchwise Scotch Whisky Production process

Scotch whiskey is produced in a two step distillation process that has remained relatively unchanged for decades, even centuries. The chemical composition of the whiskey is vital to its flavor and character. Much work has been done to analyze and study the final composition of different whiskies. However, to date little work has been published that studies the composition of the distillate with respect to distillation time. The goal of this work is to develop an experimental basis for study of the scotch whisky production process. Experimental data would allow us to gain a better understanding of the effects of distillation and aging. Samples collected during the distillation process were analyzed using gas-chromatography mass spectrometry. This analysis allowed the development of composition curves for several components found in whisky to help understand process decisions made during the distillation. The experimental data developed during the chemical analysis provided a physical basis for development of a process simulation. The simulation was done using the HYSYS® Simulation software. The batch distillation process was modeled using a tray distillation column with a large reboiler and low reflux. These conditions closely mimic the operation of the actual process. The simulation successfully modeled the experimental data for both the major and minor components. Simulation studies have also been able to produce suggestions for process improvements that could increase the economic yield of the distillery

Musical expertise as a scaffold for novice programming

textThis study addresses the role of musical expertise on novice computer programming. Engaging novices with computer programming is one of the great challenges of computer science education. Although there is extensive research focusing on constructionist approaches to programming education and creative entry points to programming, little research addresses the topic of how musical expertise informs an unstructured programming activity. To answer this question I focused on the role of participant talk during programming, patterns in participant programming, and evidence of computational thinking in participants’ final Scratch projects. For this interpretivist study, I worked with a dozen novice programmers from a variety of musical backgrounds: classical musicians, jazz musicians, composers, and non- musicians. Each participant worked on a free-form musical project in the Scratch programming environment. I collected data including participant talk, screen recordings of participant programming, and participants’ final Scratch projects. Overall, musical participants more readily took to the numeracy involved in programming music in Scratch. Also, musical participants were able to use musical concepts and techniques as jumping-off points for programming challenges. Considering my results by participant group, composers stood out in a number of ways: working the longest, testing their programs the most often, adding Scratch objects the slowest, v removing the most Scratch objects, creating projects of the greatest nested depth, and unanimous use of operators and random numbers. Non-musicians, on the other hand, worked for the shortest amount of time, added the fewest Scratch objects, and created projects of the lowest nested depth. In addition to adding to the body of research around chunking and tinkering, this study reinforces the importance of context and comfort in an introduction to computer programming. Composition may be an especially rich area to leverage, given the design- like programming activity of the composers here. Future research projects could resemble this one while focusing on younger learners, explicit musical concepts like those invoked by participants, or alternative performing arts framings such as theater or dance.Curriculum and Instructio

Leaving it on the Field: A review of the Bowl Championship Series and Proposal of a Postseason Playoff to Remedy the Negative Ethical Implications on Higher Education of the Current Model

This thesis considers the current format of the postseason for the National Collegiate Athletic Association (NCAA) Division I-Football Bowl Subdivision (FBS), critiques its ethical implications, and proposes a twelve-team postseason playoff to remedy the ethical dilemmas caused by the Bowl Championship Series (BCS) and the commercialization of football at the Division I-FBS level. Research was focused on sports law journals, books detailing the history of college football, transcripts from Congressional hearings, and articles from prominent sports news sources. The first chapter outlines the evolution of college football since the advent of television as mass media and highlights the medium’s direct effects on the administration of the sport. The second chapter details the BCS and its implementation. The third chapter calls into question the ethics of universities using football as a revenue generator without naming a NCAA champion as is done in every other sport and the lower divisions of college football. The fourth chapter lays the framework for a postseason playoff system and addresses how it resolves the conflicts of interest presented by the BCS
