Description
An eco-industrial park (EIP) is an industrial ecosystem in which a group of co-located firms are involved in collective resource optimization with each other and with the local community through physical exchanges of energy, water, materials, byproducts and services - referenced in the industrial ecology literature as "industrial symbiosis". EIPs, when compared with standard industrial resource sharing networks, prove to be of greater public advantage as they offer improved environmental and economic benefits, and higher operational efficiencies both upstream and downstream in their supply chain.
Although there have been many attempts to adapt EIP methodology to existing industrial sharing networks, most of them have failed for various factors: geographic restrictions by governmental organizations on use of technology, cost of technology, the inability of industries to effectively communicate their upstream and downstream resource usage, and to diminishing natural resources such as water, land and non-renewable energy (NRE) sources for energy production.
This paper presents a feasibility study conducted to evaluate the comparative environmental, economic, and geographic impacts arising from the use of renewable energy (RE) and NRE to power EIPs. Life Cycle Assessment (LCA) methodology, which is used in a variety of sectors to evaluate the environmental merits and demerits of different kinds of products and processes, was employed for comparison between these two energy production methods based on factors such as greenhouse gas emission, acidification potential, eutrophication potential, human toxicity potential, fresh water usage and land usage. To complement the environmental LCA analysis, levelized cost of electricity was used to evaluate the economic impact. This model was analyzed for two different geographic locations; United States and Europe, for 12 different energy production technologies.
The outcome of this study points out the environmental, economic and geographic superiority of one energy source over the other, including the total carbon dioxide equivalent emissions, which can then be related to the total number of carbon credits that can be earned or used to mitigate the overall carbon emission and move closer towards a net zero carbon footprint goal thus making the EIPs truly sustainable.

Description
As the demand for power increases in populated areas, so will the demand for water. Current power plant technology relies heavily on the Rankine cycle in coal, nuclear and solar thermal power systems which ultimately use condensers to cool the steam in the system. In dry climates, the amount of water to cool off the condenser can be extremely large. Current wet cooling technologies such as cooling towers lose water from evaporation. One alternative to prevent this would be to implement a radiative cooling system. More specifically, a system that utilizes the volumetric radiation emission from water to the night sky could be implemented. This thesis analyzes the validity of a radiative cooling system that uses direct radiant emission to cool water. A brief study on potential infrared transparent cover materials such as polyethylene (PE) and polyvinyl carbonate (PVC) was performed. Also, two different experiments to determine the cooling power from radiation were developed and run. The results showed a minimum cooling power of 33.7 W/m2 for a vacuum insulated glass system and 37.57 W/m2 for a tray system with a maximum of 98.61 Wm-2 at a point when conduction and convection heat fluxes were considered to be zero. The results also showed that PE proved to be the best cover material. The minimum numerical results compared well with other studies performed in the field using similar techniques and materials. The results show that a radiative cooling system for a power plant could be feasible given that the cover material selection is narrowed down, an ample amount of land is available and an economic analysis is performed proving it to be cost competitive with conventional systems.

Description
In this thesis the performance of a Hybrid AC System (HACS) is modeled and optimized. The HACS utilizes solar photovoltaic (PV) panels to help reduce the demand from the utility during peak hours. The system also includes an ice Thermal Energy Storage (TES) tank to accumulate cooling energy during off-peak hours. The AC runs continuously on grid power during off-peak hours to generate cooling for the house and to store thermal energy in the TES. During peak hours, the AC runs on the power supplied from the PV, and cools the house along with the energy stored in the TES. A higher initial cost is expected due to the additional components of the HACS (PV and TES), but a lower operational cost due to higher energy efficiency, energy storage and renewable energy utilization. A house cooled by the HACS will require a smaller size AC unit (about 48% less in the rated capacity), compared to a conventional AC system. To compare the cost effectiveness of the HACS with a regular AC system, time-of-use (TOU) utility rates are considered, as well as the cost of the system components and the annual maintenance. The model shows that the HACS pays back its initial cost of $28k in about 6 years with an 8% APR, and saves about $45k in total cost when compared to a regular AC system that cools the same house for the same period of 6 years.

Description
The ability to shift the photovoltaic (PV) power curve and make the energy accessible during peak hours can be accomplished through pairing solar PV with energy storage technologies. A prototype hybrid air conditioning system (HACS), built under supervision of project head Patrick Phelan, consists of PV modules running a DC compressor that operates a conventional HVAC system paired with a second evaporator submerged within a thermal storage tank. The thermal storage is a 0.284m3 or 75 gallon freezer filled with Cryogel balls, submerged in a weak glycol solution. It is paired with its own separate air handler, circulating the glycol solution. The refrigerant flow is controlled by solenoid valves that are electrically connected to a high and low temperature thermostat. During daylight hours, the PV modules run the DC compressor. The refrigerant flow is directed to the conventional HVAC air handler when cooling is needed. Once the desired room temperature is met, refrigerant flow is diverted to the thermal storage, storing excess PV power. During peak energy demand hours, the system uses only small amounts of grid power to pump the glycol solution through the air handler (note the compressor is off), allowing for money and energy savings. The conventional HVAC unit can be scaled down, since during times of large cooling demands the glycol air handler can be operated in parallel with the conventional HVAC unit. Four major test scenarios were drawn up in order to fully comprehend the performance characteristics of the HACS. Upon initial running of the system, ice was produced and the thermal storage was charged. A simple test run consisting of discharging the thermal storage, initially ~¼ frozen, was performed. The glycol air handler ran for 6 hours and the initial cooling power was 4.5 kW. This initial test was significant, since greater than 3.5 kW of cooling power was produced for 3 hours, thus demonstrating the concept of energy storage and recovery.

Description
Buildings continue to take up a significant portion of the global energy consumption, meaning there are significant research opportunities in reducing the energy consumption of the building sector. One widely studied area is waste heat recovery. The purpose of this research is to test a prototype thermogalvanic cell in the form factor of a UK metric brick sized at 215 mm × 102.5 mm × 65 mm for the experimental power output using a copper/copper(II) (Cu/Cu2+) based aqueous electrode. In this study the thermogalvanic brick uses a 0.7 M CuSO4 + 0.1 M H2SO4 aqueous electrolyte with copper electrodes as two of the walls. The other walls of the thermogalvanic brick are made of 5.588 mm (0.22 in) thick acrylic sheet. Internal to the brick, a 0.2 volume fraction minimal surface Schwartz diamond (Schwartz D) structure made of ABS, Polycarbonate-ABS (PCABS), and Polycarbonate-Carbon Fiber (PCCF) was tested to see the effects on the power output of the thermogalvanic brick. By changing the size of the thermogalvanic cell into that of a brick will allow this thermogalvanic cell to become the literal building blocks of green buildings. The thermogalvanic brick was tested by applying a constant power to the strip heater attached to the hot side of the brick, resulting in various ∆T values between 8◦C and 15◦C depending on the material of Schwartz D inside. From this, it was found that a single Cu/Cu2+ thermogalvanic brick containing the PCCF or PCABS Schwartz D performed equivalently well at a 163.8% or 164.9%, respectively, higher normalized power density output than the control brick containing only electrolyte solution.

Description
There has been a recent push for queer fiction, especially in the young adult genre, whose focus is gay and lesbian relationships. This growth is much needed in terms of visibility and the furthering of acceptance, but there are still subjects within the LGBTQ+ community that need to be addressed, including bisexual, asexual, and non-binary erasure. There are many people who claim that these identities do not exist, are labels used as a stepping stone on one's journey to discovering that they are homosexual, or are invented excuses for overtly promiscuous or prudish behavior. The existence of negative stereotypes, particularly those of non-binary individuals, is largely due to a lack of visibility and respectful representation within media and popular culture. However, there is still a dearth of non-binary content in popular literature outside of young adult fiction. Can You See Me? aims to fill the gap in bisexual, asexual, and non-binary representation in adult literature. Each of the four stories that make up this collection deals with an aspect of gender and/or sexuality that has been erased, ignored, or denied visibility in American popular culture. The first story, "We'll Grow Lemon Trees," examines bisexual erasure through the lens of sociolinguistics. A bisexual Romanian woman emigrates to Los Angeles in 1989 and must navigate a new culture, learn new languages, and try to move on from her past life under a dictatorship where speaking up could mean imprisonment or death. The second story "Up, Down, All Around," is about a young genderqueer child and their parents dealing with microaggressions, examining gender norms, and exploring personal identity through imaginary scenarios, each involving an encounter with an unknown entity and a colander. The third story, "Aces High," follows two asexual characters from the day they're born to when they are 28 years old, as they find themselves in pop culture. The two endure identity crises, gender discrimination, erasure, individual obsessions, and prejudice as they learn to accept themselves and embrace who they are. In the fourth and final story, "Mile Marker 72," a gay Mexican man must hide in plain sight as he deals with the death of his partner and coming out to his best friend, whose brother is his partner's murderer.

Description
The Way Home is a full-length young adult novel. The story is split between the perspectives of Theo and Ella, best friends from high school who are starting their freshman year in college. Neither is extremely excited about the start of the new phase of their lives; Theo struggles with severe anxiety and is just hoping to survive the four years; and dark memories in Ella's past don't seem to want to let her start over. A series of murders happening in town don't help their nerves at all, making it hard to focus on the "college experience." They were supposed to be there for each other... But then Ella goes missing, and Theo is left without a clue of where she went. While he searches for her desperately, she wakes up miles away from home, surrounded by strangers. In their efforts to find one another again, they instead find themselves presented with opportunities to study the impossible: magic. Things become stranger and stranger as murders, magic, police investigations, and ever-looming final exams begin to challenge Theo and Ella in ways they never expected. In writing this novel, I hoped to depict the transition from high school to college and the worries and wonders that come with it. The story is almost split directly in half, beginning with normal school life and shifting into the world of magic. The conflicts presented to the characters during the first half, such as grades, majors, and socializing, persist throughout the second half, but are also metaphorized once the characters begin studying magic. I chose to include a protagonist with an anxiety disorder because I believe mental disabilities are not represented enough in YA literature, though it is something that many high school and college students deal with. I wanted to create a character that could inform others and that students with similar mental disorders could relate to. Additional themes I deal with include newfound independence, individuality, growth, and friendship.

Description
"French Vanilla" is a collection of written narratives drawn from lived experiences which serve as the vehicle storytelling that I use to examine larger themes related to the intersections of race and gender. Themes include: binaries, legitimacy, intersectionality, biracial identity development (border identity construction), whiteness, shame, and crisis. While the narratives are situated within theoretical discourse, the narratives present a representation of the lived experience. These pieces engage members of my family as well as a number of figures, including Rachel Dolezal, President Barack Obama, Alicia Keys, and a stranger on a tram in an airport. My relationship with these people present the grounds for an interrogation of identity. This project asks the question: How does one negotiate biracial identity with herself and others through narrative performance? It engages theories, such as critical race theory, black feminist theory, and standpoint theory, which informed my understanding of the discourse of race and contextualized my commentary on race. These theories present a framework within which to situate my understanding and analysis of race through lived experience. Narrative performance, the formal methodology for this work, provides a structure for the performance itself: the ultimate end product. Note: This work of creative scholarship is rooted in collaboration between three female artist-scholars: Carly Bates, Raji Ganesan, and Allyson Yoder. Working from a common intersectional, feminist framework, we served as artistic co-directors of each other's solo pieces and co-producers of Negotiations, in which we share these pieces in relationship to each other. Thus, Negotiations is not a showcase of three individual works, but rather a conversation among three voices. As collaborators, we have been uncompromising in the pursuit of our own unique inquiries and voices, and each of our works of creative scholarship stand alone. However, we believe that all of the parts are best understood in relationship to each other and to the whole. For this reason, we have chosen to cross-reference our thesis documents: French Vanilla: An Exploration of Biracial Identity Through Narrative Performance by Carly Bates; Deep roots, shared fruits: Emergent creative process and the ecology of solo performance through "Dress in Something Plain and Dark" by Allyson Yoder; and Bhairavi: A Performance-Investigation of Belonging and Dis-Belonging in Diaspora Communities by Raji Ganesan.

For my creative project, I began an art press that produces small-run vinyl records and artist's books. Initially, the venture began as a means to circumvent record pressing facilities as a vinyl record-cutting service. By the end of this project, the focus shifted to encompass more visual art products than just vinyl records. The project began with vinyl records because I saw a need in the market; in the past decade, the industry has grown dramatically, but the dozen record pressing plants in the country cannot keep up with the demand. Because record pressing companies prioritize large orders, it is difficult for many small bands and independent record labels to produce work on this medium. This is due to the long lead times, high prices, and large minimum order sizes. I located a man in Germany, who invented a machine that makes high-quality, lathe-cut records. I named the project Blushing Soup, as homage to my father, who passed during my first semester of college. It is through his passing that I was able to secure funds to pursue this venture. I brought on a partner, who was more familiar with art and audio recording than myself. In the summer of 2015, we met with this inventor to learn how to use his machine. By October of 2015, a machine of our own had arrived. In early November, Blushing Soup won a grant from the Scottsdale Museum of Contemporary Art. During this time, we released two vinyl records for local bands. For a culminating project, I coordinated a Record Store Day compilation album consisting of six bands featuring. After securing all of the music, the machine started having problems, which forced me to cancel this release. Recognizing the delicacy of the machine, prompted a shift in the aim of Blushing Soup. During this process, I started learning printmaking processes, and I realized that Blushing Soup could function as more than a record cutting service; we could be an art press. In the last few month of this project, I started making artist's books. By the end of April 2016, Blushing Soup will have released vinyl records for two bands, as well as produced four handmade books. This creative project centered around the process of creating art through lathe cutting and printmaking; the objective was not to maximize profits but rather refocus the consumption of art (in a sustainable practice).
