Description
This thesis investigates the viability of a solar still for desalination of a personal water supply. The end goal of the project is to create a design that meets the output requirement while tailoring the components to focus on low cost so it would be feasible in the impoverished areas of the world. The primary requirement is an output of 3 liters of potable water per day, the minimum necessary for an adult human. The study examines the effect of several design parameters, such as the basin material, basin thickness, starting water depth, basin dimensions, cover material, cover angle, and cover thickness. A model for the performance of a solar still was created in MATLAB to simulate the system's behavior and sensitivity to these parameters. An instrumented prototype solar still demonstrated viability of the concept and provided data for validation of the MATLAB model.

Description
To supplement lectures, various resources are available to students; however, little research has been done to look systematically at which resources studies find most useful and the frequency at which they are used. We have conducted a preliminary study looking at various resources available in an introductory material science course over four semesters using a custom survey called the Student Resource Value Survey (SRVS). More specifically, the SRVS was administered before each test to determine which resources students use to do well on exams. Additionally, over the course of the semester, which resources students used changed. For instance, study resources for exams including the use of homework problems decreased from 81% to 50%, the utilization of teaching assistant for exam studying increased from 25% to 80%, the use of in class Muddiest Points for exam study increased form 28% to 70%, old exams and quizzes only slightly increased for exam study ranging from 78% to 87%, and the use of drop-in tutoring services provided to students at no charge decreased from 25% to 17%. The data suggest that students thought highly of peer interactions by using those resources more than tutoring centers. To date, no research has been completed looking at courses at the department level or a different discipline. To this end, we adapted the SRVS administered in material science to investigate resource use in thirteen biomedical engineering (BME) courses. Here, we assess the following research question: "From a variety of resources, which do biomedical engineering students feel addresses difficult concept areas, prepares them for examinations, and helps in computer-aided design (CAD) and programming the most and with what frequency?" The resources considered include teaching assistants, classroom notes, prior exams, homework problems, Muddiest Points, office hours, tutoring centers, group study, and the course textbook. Results varied across the four topical areas: exam study, difficult concept areas, CAD software, and math-based programming. When preparing for exams and struggling with a learning concept, the most used and useful resources were: 1) homework problems, 2) class notes and 3) group studying. When working on math-based programming (Matlab and Mathcad) as well as computer-aided design, the most used and useful resources were: 1) group studying, 2) engineering tutoring center, and 3) undergraduate teaching assistants. Concerning learning concepts and exams in the BME department, homework problems and class notes were considered some of the highest-ranking resources for both frequency and usefulness. When comparing to the pilot study in MSE, both BME and MSE students tend to highly favor peer mentors and old exams as a means of studying for exams at the end of the semester1. Because the MSE course only considered exams, we cannot make any comparisons to BME data concerning programming and CAD. This analysis has highlighted potential resources that are universally beneficial, such as the use of peer work, i.e. group studying, engineering tutoring center, and teaching assistants; however, we see differences by both discipline and topical area thereby highlighting the need to determine important resources on a class-by-class basis as well.

Description
Abstract Retrograde presents questions about the creation and value of art through a graphic novel. Materials used to create the work were illustration paper, ink, brushes, and printed screen tones. The piece was created in four stages: first, each panel was sketched into the first draft; second, the sketch was researched and fully developed into a complete drawing; third, the sketch was completely traced with ink and texture was added; finally, the drawing tones were added with ink and screen tones. The plot of Retrograde revolves around the protagonist, Vera, as she attempts to find a place for her art in an artistic community that rejects her for her lack of commercial success and for the advantages she got through connections. When Vera appears to have succeeded, a sudden plot twist reveals a conspiracy which undermines her success. By following Vera, the novel illustrates a corrupt artistic society in which the value of art is established by a small amount of artistic elites. The written portion of the project expounds on the various ideas that drove the novel, including how art forms like graphic novels come to be situated low in artistic hierarchies and how interpretations can be negatively guided by already established institutions. Among some of the theorists referenced within the paper are Walter Benjamin, Clement Greenberg, and Susan Sontag. In conclusion, the project illustrates an inclination to judge art by potential commercial value and by already established hierarchies, limiting the possibilities of new interpretations and shifts in those same hierarchies. Keywords: art, art theory, graphic novels

Description
Recurring incidents between pedestrians, bicycles, and vehicles at the intersection of Rural Road and Spence Avenue led to a team of students conducting their own investigation into the current conditions and analyzing a handful of alternatives. An extension of an industry-standard technique was used to build a control case which alternatives would be compared to. Four alternatives were identified, and the two that could be modeled in simulation software were both found to be technically feasible in the preliminary analysis.

Description
Perspection is an art exhibition dealing with the ideas of perspective and perception, as it relates to observation of artwork. As a viewer, art is seen as an inanimate thing, however, so much time is spent in the conception and execution of a piece that it begins to take on a life of its own. This thesis is the exploration of how art has the power to come alive, creating conversations with a viewer while showing them another way to observe the world around them.

Description
‘why we bend' a Bachelor of Fine Arts honors thesis exhibition by Ximenna Hofsetz and Tiernan Warner brings together installation, digital, sculptural, and printed artwork. The main focus concerns memory; and its vague, formless, and hazy nature. The work also examines what would happen if cognitive space could be physically mapped? What would it look like in sculptural form? Memory erodes and distorts with time. We influence our memories as much as they affect us. Thus, just as relationships are ever-changing, and our memories of those we interact with constantly shifting, our relationships with our own memories are malleable and evolve through time. This transient nature of memory is depicted in the various stylistic means of this exhibition by referencing time and space as well as personal memories and ephemera in both concrete and abstract ways. ‘why we bend’ implements a variety of multimedia techniques to examine recollection and its hold on us.

How do we visualize environments outside our solar system? I have researched two very alien planets and their compositions with the goal of finding out how those differences would affect the way a planet appears on its surface. The first is a planet orbiting the nearby G type star Tau Ceti. This star has Mg/Si ratio of 1.78, compared to 1.2 found on the Earth. A planet formed around this star could have a very active surface, covered in volcanoes. The other planet is a hypothetical carbon planet that could orbit the star HD 144899. This star has a C/O ratio of 0.8, compared to 0.5 in the Sun. A planet formed here might be comprised mostly of carbides, with a hydrocarbon atmosphere. It would likely be geologically dead, the main forces shaping its surface being meteorites. Both planets, due to their extremes, would likely be barren and lifeless. The results of this project are two digital paintings showcasing my vision of these planets.

Description
The following document addresses two grand challenges posed to engineers: to make solar energy economically viable and to restore and improve urban infrastructure. Design solutions to these problems consist of the preliminary designs of two energy systems: a Packaged Photovoltaic (PPV) energy system and a natural gas based Modular Micro Combined Cycle (MMCC) with 3D renderings. Defining requirements and problem-solving approach methodology for generating complex design solutions required iterative design and a thorough understanding of industry practices and market trends. This paper briefly discusses design specifics; however, the major emphasis is on aspects pertaining to economical manufacture, deployment, and subsequent suitability to address the aforementioned challenges. The selection of these systems is based on the steady reduction of PV installation costs in recent years (average among utility, commercial, and residential down 27% from Q4 2012 to Q4 2013) and the dramatic decline in natural gas prices to $5.61 per thousand cubic feet. In addition, a large number of utility scale coal-based power plants will be retired in 2014, many due to progressive emission criteria, creating a demand for additional power systems to offset the capacity loss and to increase generating capacity in order to facilitate the ever-expanding world population. The proposed energy systems are not designed to provide power to the masses through a central location. Rather, they are intended to provide economical, reliable, and high quality power to remote locations and decentralized power to community-based grids. These energy systems are designed as a means of transforming and supporting the current infrastructure through distributed electricity generation.

Description
Language is powerful. The words we use define our perceptions. They label what we see and paint a picture for those with whom we are communicating. Words serve as heuristic when assigning value to an object, experience, or person. My thesis, Eye of the BeholdHer, focuses on the language used in American pop-culture to describe women. I comment on the dehumanization of women through the use of animal names used to describe personality, appearance, and genitalia, as well as the way the English language implies domestication and inferiority of women through the use of the certain words. Examples include, but are not limited to: bitch , chick, pussy, beaver, cougar, catty, heifer, old bat, mousy, foxy, and vixen. Eye of the Behold(her) reflects upon my observations and calls for social change. Eye of the BeholdHer is a call for action. It is time to make conscious word choices and realize the impact words have on shaping our society. It is time for us to empowHer through words.
