Generating and manipulating painterly renderings of images

Creator:: Todd, Grace
Abstract:: We present a tool that converts any image into a painterly rendered one, or one that looks as though it was hand-painted. To do this, we implemented the Sobel filter to calculate the edge field that is used to create streamlines, which serve as the foundation for brush strokes. We...

Assessing the Feasibility of Utilizing UAS-Based Point Clouds for Pavement Smoothness/Roughness Quantification

Creator:: Sen, Fatih
Abstract:: Transportation agencies continuously strive to improve driving quality and highway safety, which are both highly correlated with the level of smoothness of the road. The International Roughness Index (IRI) is a widely adopted, standardized metric calculated from longitudinal profile data collected on the road. Inertial profilers are devices mounted to...

Communication-Efficient Secure Two-Party Computation From Minicrypt and OT

Creator:: Roy, Lawrence
Abstract:: Secure two-party computation (2PC) is the task of performing arbitrary calculations on secret inputs provided by two parties, while maintaining secrecy if at least one party is honest. 2PC has been applied to privacy-preserving record linkage and machine learning, in areas such as medicine where maintaining privacy is crucial. One...

Munition Mobility in Mixed Grain (Sand and Cobble) Environments

Creator:: Paskoski, Jessica
Abstract:: Nearly 24% of Formerly Used Defense Sites (FUDS) containing military munitions are in the nearshore coastal zone with approximately 30% of those sites containing heterogeneous sediment compositions of gravel-sand. Previous exploration in munition mobility was performed on beaches of sandy or muddy bottoms leaving the influence of heterogeneous sediment properties...

Virtual Americans with Disabilities Act Compliance Assessment of Curb Ramps Using Lidar Point Clouds: A Framework to Simulate Digital Inclinometers for Slope Measurements

Creator:: Zhou, Yang
Abstract:: A curb ramp is an indispensable ramp system in the transportation network that provides a transition between a sidewalk and a roadway. The Americans with Disabilities Act (ADA) requires that the design, construction, and maintenance of curb ramps meet the ADA standards. However, many existing curb ramps are noncompliant, as...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Additive Manufacturing of FeCrCoCuNi High Entropy Alloy via Laser Powder Bed Fusion and Nickel Aluminum Bronze via Laser Directed Energy Deposition

Creator:: Doyle, Ryan P.
Abstract:: High Entropy Alloys (HEA) exhibit unusual properties and are gaining interest as new materials for challenging applications in the aerospace, hypersonic and medical fields. The application of HEAs have been limited by the development of powder production at scale. A recently developed process of plasma spheroidization by 6K, inc. has...

Guided Translation of Algorithmic Notation into Functional Programs

Creator:: Fedorin, Danila
Abstract:: The use of board games for teaching introductory computer science is a promising recent avenue of research. The goal is to introduce computing concepts through their use in the implementations of simple games, thereby keeping students engaged through their learning process. However, there is a gap between students' algorithmic descriptions...

Cost-Age-Time Data Organized Garbage Collection

Creator:: Lee, Dongjun
Abstract:: NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...
