Trip Based Modeling Of Fuel Consumption In Modern Heavy-Duty Vehicles Using Artificial Intelligence, Sasanka Katreddi, Arvind Thiruvengadam

Faculty & Staff Scholarship

Heavy-duty trucks contribute approximately 20% of fuel consumption in the United States of America (USA). The fuel economy of heavy-duty vehicles (HDV) is affected by several real-world parameters like road parameters, driver behavior, weather conditions, and vehicle parameters, etc. Although modern vehicles comply with emissions regulations, potential malfunction of the engine, regular wear and tear, or other factors could affect vehicle performance. Predicting fuel consumption per trip based on dynamic on-road data can help the automotive industry to reduce the cost and time for on-road testing. Data modeling can easily help to diagnose the reason behind fuel consumption with a …

More Alike Than Different: Student Perceptions Of Academic Librarians By Genders And Subject Areas, Elizabeth Price, Jody C. Fagan

Libraries

This study explored differences in how undergraduate students of different genders and academic disciplines perceived academic librarians at a U.S. public university. No evidence indicated differences between students identifying as male or female, and few statistically significant differences were found among four Subject Areas (Arts, Humanities + Social Sciences, Business, Health + Education, and STEM). Our results have implications for local practice though they are not generalizable to other institutions. Despite a lack of significant findings, librarians should continue to explore ways to measure how students of different disciplines perceive academic libraries and/or librarians as valuable to their academic success.

Secret Sharing And Its Variants, Matroids,Combinatorics., Shion Samadder Chaudhury Dr.

Doctoral Theses

The main focus of this thesis is secret sharing. Secret Sharing is a very basic and fundamental cryptographic primitive. It is a method to share a secret by a dealer among different parties in such a way that only certain predetermined subsets of parties can together reconstruct the secret while some of the remaining subsets of parties can have no information about the secret. Secret sharing was introduced independently by Shamir [139] and Blakely [20]. What they introduced is called a threshold secret sharing scheme. In such a secret sharing scheme the subsets of parties that can reconstruct a secret …

Functional Characterization Of Arabidopsis Synaptotagmin-4 Protein Through Reverse Genetics Strategy, Zahid Jawed

Theses and Dissertations

Calcium ion plays a significant role in plant signal transduction pathways, including regulation of stress-induced gene expression. Sensor proteins such as proteins with calcium-binding C2 domains can perceive changes in cellular calcium level. Functional analysis of such sensor proteins will give us a better understanding of plant stress signaling. Synaptotagmins are a group of proteins containing C2 domains that are capable of binding calcium ions and regulate gene expression in response to external abiotic stress stimuli. Here, we used a reverse genetic approach to analyze the function of synaptotagmin – 4, which is one of the five identified synaptotagmin proteins …

The Influence Of Teleconnection Patterns On Renewable Energy Resources, John Kyle Bergerson

Master's Theses

Energy providers are shifting their supply from carbon based forms of energy to renewable sources in response to policy changes aimed at reducing pollution and anthropogenic influence on the environment. Wind and solar energies are notable sources that have been adopted around the globe and are increasing in installation and efficiency, but relying on weather-dependent sources of energy has limitations. Variability in energy supply and demand becomes further dependent on the state of the climate, and thus predictability of that state is critical. Climate modes are correlated with climate variables and are used to make mid-term (>10 days), seasonal, …

Looking Into The Future: Predicting Future Video Frames Using Monocular Depth Estimation And Egomotion, Meera Kumar

Master's Theses

Micro-mobility has become a growing market that has altered transportation withincities. While helping people reach their destination efficiently while using fewer fossil fuels and resources, e-scooters lack tailored safety protocol. Using depth and ego-motion machine learning estimation through a live video stream, we hope to identify possible oncoming hazard for e-scooter users. To approach this problem, we tested methods that removed the pose network with a scaling transformation which was derived via linear regression. Our intuition was that training and inference will be faster with the removal of the pose network and was validated by the results. We also found …

Linear Inverse Problems And Neural Networks, Jasjeet Dhaliwal

Master's Theses

We investigate two ideas in this thesis. First, we analyze the results of adaptingrecovery algorithms from linear inverse problems to defend neural networks against adversarial attacks. Second, we analyze the results of substituting sparsity priors with neural network priors in linear inverse problems. For the former, we are able to extend the framework introduced in [1] to defend neural networks against ℓ0, ℓ2,and ℓ∞ norm attacks, and for the latter, we find that our method yields an improvement over reconstruction results of [2].

Ionic Percolation Networks In Composite Electrodes For All-Solid-State Batteries, Corey G. Abraham

Master's Theses

As the demand for high performance lithium-ion batteries grows, materials research isneeded to provide a safer alternative to the use of flammable liquid electrolytes. All-solid-state composite electrolytes consisting of a polymer host and ceramic filler can balance both the need for high ion-conductivity and mechanical flexibility within operating battery systems. The high interfacial resistances between such electrolytes and electrodes, as well as within porous electrodes, however, is a prohibitive performance attribute characteristic of this class of materials. One strategy to mitigate the inhibitory diffusion kinetics associated with the interface is to introduce an ionic percolation network into the electrodes. This …
