Using Wavelets to Compress Acoustic Data
No full textThis research investigates the use of wavelets to compress acoustical data. The power spectral densities of acoustic data before and after wavelet decomposition, compression, and recomposition are compared to assess the quality of compression. Cross-correlation is used to compare the amplitude peaks of the power spectral densities
Throwing Shade
No full textA mid century woman looks off into the distance while she is tied to the phone on the wall. She is the talebearer. Gossip is not a dirty word. Women have used “gossip” as a means of communication since the beginning of time. It is how we keep ourselves connected to one another, and informed of the goings-on around us. Everyone gossips
Northern Hogsucker AEP Experimentation of Frequency in Comparison to Size
No full textWe tested hearing in the Northern Hogsucker using the auditory evoked potential (AEP) recording technique, a non-invasive electrophysiological approach that allows rapid evaluation of hearing and repeated testing of animals. The AEP technique is used to study the effects of sound/noise levels on hearing by measuring the temporary threshold shifts after exposure to the sound/noise. Northern Hogsucker are members of the otophysan lineage of fishes, which share an anatomical modification for enhanced hearing sensitivity relative to most non-otophysan fishes. This special hearing anatomy (Weberian apparatus) involves a chain of small bones, called Weberian ossicles, that connect the swim bladder to the ears. The Weberian apparatus of otophysans is associated with increased sensitivity to a wider range of sound frequencies, however, the auditory sensitivity of most otophysans is unknown. Further, how size-related changes in Weberian apparatus function and hearing sensitivity are largely unknown. We set out to determine the frequency range and sensitivity of hearing in the Northern Hogsucker (Hypentelium nigricans)
Reading the Room: Memory, Dwelling, and the Everyday
Get PDFIn any space, there is a residue that coats the present with a patina of memory. Creating layered imagery in dream-like paintings and prints, I use the domestic realm as a metaphor for the internal world of the mind, memories, and private thoughts, including them in compositions with symbols like the boundaries of windows, doors, and gates. These metaphorical structures also portray outward identities, which guard inner emotions. The conceptual aspects of these compositional elements weave together memories of the past and places of the present into a unified whole.
I began graduate school at the beginning of the COVID-19 pandemic. I often found myself observing different dwellings within and outside of my personal spaces. My intention is to show the connection between our dwellings and minds and how the environment can influence a mental state
Hydrological Modeling for the Impact of Predicted Climate Change and Urbanization: A Case Study of the Lower Mississippi River Basin
Get PDFThe Mississippi River Basin is the United States’ largest watershed and consists of many subbasins. Each subbasin has hydrological processes including flow rate, evapotranspiration, and groundwater flow. It is important to understand how these processes change through shifts in weather, time, and land use. This study uses the Soil and Water Assessment Tool (SWAT) to predict how changes in temperature, rainfall, and land use can change hydrological processes responses. This study concludes that, for the studied subbasin, a high representative concentration pathway (RCP) will result in lower flow rates and ground water flow as well as higher evapotranspiration by the year 2080. Additionally, as this area becomes urbanized, the average flow rate can be expected to increase by 3.07cms with 106.12cms higher peak flow, the evapotranspiration can be expected to have a peak flow of 1.01mm/day higher, and the average ground water can be expected to drop by 0.85mm/day

Get PDFIn their artwork Bianca Walker takes a refreshing and historically engaging approach to the act of painting. After researching through photographic references of black people from the early 1900s the artist reimagines these photographs as painted portraits using a drip painting method purposely eliminating paint brushes from their practice. Incorporating more utilitarian materials such as drop cloth and palms, the artist’s relationship to the traditional act of paintings versus their current practice mirrors the current point of view placed upon and change of view that they would like to be seen in conversations around black working-class people from this period
Perceptions of sub-Saharan African International Students in United States: Mental Health Concerns and Help-Seeking Behavior
Get PDFInternational students face a lot of challenges while studying abroad, with or without the supportive system that their families provide. Sub-Saharan Africa international students consists of 3.7 percent of the population, which indicates a 2.1 percent increase prior to previous year. While in the host country, this population is saddled with the self-responsibilities of maintaining their values, cultural identities, personality, language ability, self-perceptions, and attitudes. African international students adopt a masking behavior in the form of adaptive strategies that could hide the mental health concerns experienced.
The purpose of this constructivist grounded theory study was to explore the untold lived experiences of sub-Saharan African international students as they face various challenges and coping strategies, while adjusting to the cultural differences experienced in America. An intensive semi-structured interview method was adopted to gather data from the eight participants, and data was analyzed using grounded theory. The conceptual framework that was integrated to guide the study was the Health Belief Model.
The study shed light into perceptions about mental health and help-seeking behavior described by the participants. The five themes that emerged were: (a) ethnic group support; (b) psychological struggles; (c) thoughts about services; (d) counselor cultural responsiveness and humility; and (e) counseling process mistrust. The themes suggest that the participants experienced transitional challenges adjusting to the United States; and opting for counseling service was not a preferred help-seeking decision due to gaps in information. The outcome translates into different ways that help can be channeled to this population, whilst providing insights into culturally appropriate methods that the university counseling center can integrate to facilitate early services. Culture affects how mental health is viewed, an approach that tends towards cultural lens needs to be applied when providing services to international students for them to complete the counseling process
Freaky Shit
Get PDFIn this reflection paper, I will be discussing the in-depth process of filming my thesis film, Freaky Shit. I will cover the extensive journey of the pre-production to post-production process and the lessons I learned along the way. My experience at The University of New Orleans will be shared as well as the knowledge and resources the Film Production program gifted me. In closing, I will be speaking on my short-term and long-term goals post-graduation as a filmmaker
