Optimizing BCI for Real-Time Performance with TensorFlow
Full text linkDeveloped a 1-Dimensional Convolutional Neural Network model and trained to translate electroencephalography (EEG) signals into drone commands. Using a 16-channel EEG headset at a 125 Hz sampling rate raw data was collected and further processed for feature extraction and training of the model to control drone movements using commands, backward, forward, left, right, land, and takeoff based on the classification of brain wave patterns. The developed model was trained on raw EEG dataset of 2,498,750 entries and achieved an accuracy of 99.27%. Though the model performed well in classifying the brain wave patterns, based on commands, it struggled slightly in differentiating \u27Takeoff\u27 and \u27Forward\u27 commands because of the non-uniform size of the dataset

Chronology and Cultural Identity at an Awaxawi Hidatsa Village on the Missouri River
Full text linkThe Amahami Village site (32ME8) is a late precontact and protohistoric era site located in the town of Stanton near the confluence of the Knife and Missouri Rivers in North Dakota. It is one of the only sites that is definitively known to be associated with the Amahami/Awaxawi subdivision of the Hidatsa. Awaxawi occupation of the site has been previously surmised to begin circa 1797, and historical records indicate that it was abandoned following a smallpox epidemic in 1834. A re-examination of the historical documentation concerning the site suggests that the date range for the Awaxawi occupation of the site may begin slightly earlier in time. Portions of the site were excavated in the 1970s, and a small number of publications resulted from this work. Christopher Dill’s 1975 master’s thesis identified some of the problems of Hidatsa culture history that the collection from the site could potentially address. Previous work also identified an early component, which was tentatively assigned to the Nailati phase (1300-1400 AD). Further excavation was completed at the site in 2016, and the more recent collection is the primary subject of the current project. Analysis of pottery and trade goods within the site confirms the presence of two discrete occupations, but it demonstrates that they are less spatially separated than previously asserted based on the 1970s excavations. Pottery from the later occupation serves as a data point in ongoing research aimed at distinguishing between Protohistoric Mandan and Hidatsa assemblages, while pottery from the early occupation allows for a refining of the timeline of the site’s early occupation. New radiocarbon dating results indicate that the early occupation may have begun earlier and lasted longer than previously suggested, potentially spanning both the Nailati phase and the earlier Clark’s Creek phase (1200-1300 AD). These radiocarbon dates and the pottery types associated with the features that were dated may also have broader implications for the dating of S-rim pottery wares in the region

Developing Methodology to Validate a Novel Carbon Delivery System for Enclosed Agriculture
Full text linkMetabolism control of plants has contributed to advancements in biopharming and horticulture over the last few decades. The last element that has yet to be controlled when talking about plants is carbon dioxide (CO2). Being able to control this element would lead to increased production for enclosed agriculture and industrial uses. The purpose of this study is to provide a carbon neutral method of controlling the metabolism of plants utilizing CO2 to optimize production yields. It began with developing the methodology to provide optimal CO2 coverage and saturation to the leaves, bypassing the stomata, the plants method of obtaining carbon. Experimenting on mister heads and mister head spacing for optimal leaf surface area coverage, creating a biofilm of concentrated carbon was the next step in controlling CO2 delivery. Verification of carbon delivery and increased photosynthesis and carbon fixation was done through the quantification of introduced agrobacterium to the subject plant, Solanum Lycopersicum (Better Boy). in treatment and control groups. This concluded that metabolism control occurred utilizing this novel carbon delivery method
SPEECH SYNTHESIS BY SYLLABLE A CONCATENATION: EXPERIMENTATION WITH BETINE
Full text linkThe endangerment of minority languages has reached pandemic proportions. No country or continent is spared. The editors of Ethnologue (2019:14-15) report that 2,923 of the world’s 7,111 languages are critically endangered. McWorther (2003:257-8) adds that, statistically speaking, “A language dies roughly every two weeks.” UNESCO (2010) projects that 90% of the world’s indigenous languages will be dead by the end of 2100. In Africa alone, Kandybowicz and Torrence (2017:3) note that 201 languages of the estimated 2000 languages have already died, and 308 others are on the brink of extinction. Minority languages worldwide are in such deplorable conditions that the United Nations (UN) has sounded the alarm about this impending linguistic catastrophe of apocalyptic proportions. It has declared 2022-2032 the International Decade of Indigenous Languages (IDIL 22-32). A simpler and nimbler speech synthesis that is based on syllable concatenation is described in this paper with the hope that it can be duplicated to revitalize critically endangered languages in Africa and elsewhere
Listening to Our Bodies: Adapting Member Checks in Community Workspaces
Full text linkDuring the COVID-19 pandemic, researchers, scholars, and members of the medical field alike found themselves struggling to balance their regular tasks and projects with the additional physical, mental, and emotional stressors of the epidemic. This paper examines the exploratory efforts of a small virtual workspace group—researchers, public health officials, and graduate students alike—to take a more health- and body-centered approach to their to-do lists and researcher commitments. Participants were driven by a question: what does it look like to structure one’s work time and agenda in a more mentally, emotionally, and physically holistic way? What started out as a purely accountability-enhancing weekly virtual workspace ended up developing into a space where participants experimented with a strategy to address this question. Ultimately, this paper explores the process by which a group of researchers developed and implemented the idea of health checks—letting one’s emotional and mental wellness state shape their project priorities just as much as urgency and obligation—at a small scale and in a community-centered environment. Using a chronological narrative, the paper articulates the development of this structure, ending with reflections from all group members about their experiences implementing health checks and their considerations for its future application
