Description
In this study, the packaging and labeling of milk and coffee was compared between Walmart and Sprouts. The pricing, the sourcing, the certifications and the overall shelf presence of the items was taken under consideration. After studying the packaging of both, a new design incorporating the applicable labels, customer appeal and appropriate green marketing was created for both the commodities.

Description
The objective for Under the Camper Shell was to build a prototype of a full living environment within the confines of a pickup truck bed and camper shell. The total volume available to work with is approximately 85ft3. This full living environment entails functioning systems for essential modern living, providing shelter and spaces for cooking, sleeping, eating, and sanitation. The project proved to be very challenging from the start. First, the livable space is extremely small, being only tall enough for one to sit up straight. The truck and camper shell were both borrowed items, so no modifications were allowed for either, e.g. drilling holes for mounting. The idea was to create a system that could be easily removed, transforming it from a camper to a utility truck. The systems developed for the living environment would be modular and transformative so to accommodate for different necessities when packing. The goal was to create a low-water system with sustainability in mind. Insulating the space was the largest challenge and the most rewarding, using body heat to warm the space and insulate from the elements. Comfort systems were made of high density foam cushions in sections to allow folding and stacking for different functions (sleeping, lounging, and sitting). Sanitation is necessary for healthy living and regular human function. A composting toilet was used for the design, lending to low-water usage and is sustainable over time. Saw dust would be necessary for its function, but upon composting, the unit will generate sufficient amounts of heat to act as a space heater. Showering serves the functions of exfoliation and ridding of bacteria, both of which bath wipes can accomplish, limiting massive volumes of water storage and waste. Storage systems were also designed for modularity. Hooks were installed the length of the bed for hanging or securing items as necessary. Some are available for hanging bags. A cabinetry rail also runs the length of the bed to allow movement of hard storage to accommodate different scenarios. The cooking method is called "sous-vide", a method of cooking food in air-tight bags submerged in hot water. The water is reusable for cooking and no dishes are necessary for serving. Overall, the prototype fulfilled its function as a full living environment with few improvements necessary for future use.

Description
Now dry and broken, the Salt River once supplied a great legacy of Riparian vegetation through the Sonoran desert. This verdant landscape flourished from perennial flows of a river fed by high mountain snowmelt. However, multiple dams within those mountain canyons and channelization for the purpose of flood protection have nearly dried up the Salt. Through the process of design I examined the potential to repair, restore, and redevelop the river, choosing a site within the reach of the Salt River that currently includes an artificial retention area called Tempe Town Lake. Since 1999 a two mile portion of the river channel has contained the reservoir for the purpose of recreation and development within the city of Tempe. As I investigated the viability of restoring an urban desert river to a more natural riparian condition, I developed a master plan that merges ecological river restoration with sustainable urban development. Research into the vegetative communities historically occurring along the river's edge guided me to create a project based in ecological principles. Expanding the concrete channel to a wider river presence followed examples set by case studies and the historic character of the Salt River. A new braided low flow channel, allowed to meander with the natural currents of the river, is terraced upwards in a gentle slope that maintains current 500-year flow plains. The vegetation communities I propose to establish along the new terraced elevations are adapted from Charles H. Lowe's profile of a foothill canyon and archival research specific to this portion of the Salt River. As a way to support the reintroduction of Arizona's lost riparian plant communities, the master plan incorporates the use of greywater and A/C condensate collection from proposed developments along the river's edge. These new water systems would be substantial enough to sustain riparian vegetation creation and in addition, provide for ground water recharge. Additional developments continue the City of Tempe's goal to expand development along the river and adjacent to the downtown core. Providing for increased recreational opportunity in a river setting improves the quality of life in Tempe and sets the community apart from surrounding desert cities. By applying ecological and sustainable design and planning principles, the Salt River Diaries master plan repairs the river's flow, restores the riparian vegetation, and redevelops the edge between the city and river.

Description
The brain continuously monitors speech output to detect potential errors between its sensory prediction and its sensory production (Daliri et al., 2020). When the brain encounters an error, it generates a corrective motor response, usually in the opposite direction, to reduce the effect of the error. Previous studies have shown that the type of auditory error received may impact a participant’s corrective response. In this study, we examined whether participants respond differently to categorical or non-categorical errors. We applied two types of perturbation in real-time by shifting the first formant (F1) and second formant (F2) at three different magnitudes. The vowel /ɛ/ was shifted toward the vowel /æ/ in the categorical perturbation condition. In the non-categorical perturbation condition, the vowel /ɛ/ was shifted to a sound outside of the vowel quadrilateral (increasing both F1 and F2). Our results showed that participants responded to the categorical perturbation while they did not respond to the non-categorical perturbation. Additionally, we found that in the categorical perturbation condition, as the magnitude of the perturbation increased, the magnitude of the response increased. Overall, our results suggest that the brain may respond differently to categorical and non-categorical errors, and the brain is highly attuned to errors in speech.

Description
Cochlear implant (CI) successfully restores hearing sensation to profoundly deaf patients, but its
performance is limited by poor spectral resolution. Acoustic CI simulation has been widely used
in normal-hearing (NH) listeners to study the effect of spectral resolution on speech perception,
while avoiding patient-related confounds. It is unclear how speech production may change with
the degree of spectral degradation of auditory feedback as experience by CI users. In this study,
a real-time sinewave CI simulation was developed to provide NH subjects with auditory
feedback of different spectral resolution (1, 2, 4, and 8 channels). NH subjects were asked to
produce and identify vowels, as well as recognize sentences while listening to the real-time CI
simulation. The results showed that sentence recognition scores with the real-time CI simulation
improved with more channels, similar to those with the traditional off-line CI simulation.
Perception of a vowel continuum “HEAD”- “HAD” was near chance with 1, 2, and 4 channels,
and greatly improved with 8 channels and full spectrum. The spectral resolution of auditory
feedback did not significantly affect any acoustic feature of vowel production (e.g., vowel space
area, mean amplitude, mean and variability of fundamental and formant frequencies). There
was no correlation between vowel production and perception. The lack of effect of auditory
feedback spectral resolution on vowel production was likely due to the limited exposure of NH
subjects to CI simulation and the limited frequency ranges covered by the sinewave carriers of
CI simulation. Future studies should investigate the effects of various CI processing parameters
on speech production using a noise-band CI simulation.

Description
Asthma is one of the most common chronic conditions in the United States, being diagnosed in over 20 million Americans. The condition is even more common among young children, and their academic performance and ability to attend school can be negatively impacted by poorly-managed asthma. Digital therapeutics are therapeutic interventions driven by high quality software programs to prevent, manage, or treat a medical disorder or disease. Technology in the healthcare space is rapidly improving, and smart devices are becoming more common everyday. How can digital therapeutics and evolving technology be implemented to make life easier for those that suffer from asthma and chronic obstructive pulmonary disease? My research seeks to answer the overarching question: How might we improve the day-to-day experience of children with asthma? Airie is a system of devices and products that educate both asthmatic children and their parents about the condition, facilitate self-monitoring and asthma management skills, and improve overall quality of life.
