Analytical Performance Evaluation Of Denm Loss In V2v Sidechannel Communications, Avijit Sarker Jan 2024

Analytical Performance Evaluation Of Denm Loss In V2v Sidechannel Communications, Avijit Sarker

Electronic Theses and Dissertations

The objective of this dissertation is to quantify the loss of Decentralized Environmental Notification Messages (DENMs) in a vehicle-to-vehicle (V2V) scenario in which DENMs are transmitted over subchannels of the sidelink (SL) specifically allocated for DENM transmission, with vehicular user equipments (VUE) autonomously selecting and managing the radio resources for transmitting DENMs. A slot-based discrete parameter, discrete-valued Markov Chain (DVMC) model that reflects DENM generation requirements for an ensemble of VUEs is developed. This model simultaneously acknowledges the potentially bursty nature and correlations within the DENM generation process and is used to assess DENM loss. DENM loss is determined according …


The Effects Of High School Scheduling Models On Student Achievement In Mississippi, Dustin Ryan Payne Jan 2024

The Effects Of High School Scheduling Models On Student Achievement In Mississippi, Dustin Ryan Payne

Electronic Theses and Dissertations

This study investigates the effects of different high school scheduling practices on student achievement in Mississippi, considering school economic status as a covariate. Using a robust factorial ANOVA design, the research analyzes reading proficiency, math proficiency, and Mississippi Statewide Accountability System school performance scores across 149 public high schools, excluding those with grades other than 9 through 12, private schools, and charter schools. The primary goal was to determine whether schedule type significantly influences academic performance, independent of economic status. Results indicate that while economic status consistently affects student and school performance, schedule type alone does not show a statistically …


Statistical Modeling Of Bankruptcy Data, Andrew Elsfelder Jan 2024

Statistical Modeling Of Bankruptcy Data, Andrew Elsfelder

Williams Honors College, Honors Research Projects

My project uses a dataset of bankrupt and non-bankrupt companies in Taiwan from 1999 to 2009. This data was collected from the Taiwan Economic Journal. The statistical methods I used to model the data are CHAID, CART, and logistic regression. The models created are tools that can predict if a company is bankrupt, or not-bankrupt based on other data about the company. I created multiple models for each of the methods to find the best model for each method. I then analyzed the output from each method. Lastly, I determined which model was the best for this data based on …


Robot-Based 3d Printing, Aaron Hoffman Jan 2024

Robot-Based 3d Printing, Aaron Hoffman

Williams Honors College, Honors Research Projects

Details of a large-format 3D printer created to print experimental materials, test multi-axis print techniques, and quickly print large objects. The printer consists of a 7-axis robotic arm and pellet extruder, which are controlled by a PC. Experimental materials such as recycled polymers or carbon-fiber reinforced materials can be easily tested with the pellet format of the extruder. The printer can perform different printing techniques and can be used to experiment with material properties when using these techniques with different polymers. The print surface is around 5 times larger than the average commercial 3D printer, and the robotic arm provides …


Wetting Transition Of 3d-Printed Surface Features, Delia Weitzel Jan 2024

Wetting Transition Of 3d-Printed Surface Features, Delia Weitzel

Williams Honors College, Honors Research Projects

This project aims to build on the previous research of prior students in the study of the wetting transition of a textured, 3D-printed surface. The surfaces studied will be constructed by a resin printer in the lab and will be composed of an array of uniform, microscopic pillars. Features of the textured surface, such as pillar diameter, pillar spacing, and pillar height, will be varied to study the impact on the wetting transition of water, oil, and a combination of water and oil. The wetting transition is defined as a transition from a state where the surface cavities are occupied …


Tropical Fish Study In Tahiti, French Polynesia, Miranda Brainard, Caitlyn Swango, Paityn Houglan, Richard Londraville Jan 2024

Tropical Fish Study In Tahiti, French Polynesia, Miranda Brainard, Caitlyn Swango, Paityn Houglan, Richard Londraville

Williams Honors College, Honors Research Projects

In May of 2023, I embarked on an exciting research journey to Moorea, French Polynesia, alongside fellow students and faculty members from the University of Akron and Syracuse University. This expedition was part of the university-sponsored Tropical Vertebrate Biology course, where we delved into the exploration of various tropical species inhabiting the island, including sea urchins, geckos, and my primary focus, the blackspotted rockskipper.

My research team, composed of my co-authors and me, was particularly intrigued by the unique refuge-seeking behavior displayed by blackspotted rockskippers. These amphibious fish are renowned for their remarkable ability to inhabit tide pools and rocky …

Does Stem Integration In High School Mathematics Classes In Underserved Schools Benefit Students' Standardized Testing Outcomes?, Steve Heinold Jan 2024

Does Stem Integration In High School Mathematics Classes In Underserved Schools Benefit Students' Standardized Testing Outcomes?, Steve Heinold

Indiana STEM Education Conference

STEM education in Indiana has become increasingly popular with, among many other factors, the recent focus by the Indiana Department of Education on the STEM workforce pipeline and school STEM certification (IDoE, 2023b). Some previous research has shown that integrating STEM into science classes and afterschool spaces has helped students from low-income communities catch up to their higher-income peers on assessments like high-stakes standardized testing (Bartell et al., 2008; Hurley, 2001; Weissglass, 2011). However, regarding STEM integration into mathematics classes, it can be more challenging than integration into other classes like science (Walker, 2016) and large gaps remain in the …
