Investigation Of Phase Change In A36 Steel As A Result Of High Velocity Impact Loading, Mena Slewa

College of Engineering: Graduate Celebration Programs

High velocity projectiles cause severe damage to target materials upon impact. The target material is subject to high pressure and temperature over a very short period of time. This work studies the effects of Lexan projectiles impacting A36 steel at velocities between 3 km/sec and 6 km/sec. The damage zone develops in the target within 5 microseconds. Some steel materials go through a reversible phase change when subject to elevated temperature and high quasi-static pressure. It is unknown whether A36 steel experiences this phase change during high velocity impact. The objective of this work is to investigate if any permanent …

Incorporating The Oceanic-Atmospheric Climate Variables To Enhance Streamflow Reconstruction Skill, Saria Bukhary, Parker Hill, Ajay Kalra, Sajjad Ahmad

College of Engineering: Graduate Celebration Programs

Streamflow is a vital source of water supply. Information about the historic streamflow helps understand the range of climate variability and develop sustainable water management strategies for the future. The available instrumental data is usually limited and thus might be insufficient to describe the long-term hydrologic patterns of a region. Streamflow reconstruction, by increasing the length of the hydrologic data, is an important tool to understand past hydrology.

Graphical Performance Measures For Practitioners To Triage Split Failure Trouble Calls, Richard S. Freije, Alexander M. Hainen, Amanda L. Stevens, Howell Li, W Benjamin Smith, Hayley Summers, Christopher M. Day, James R. Sturdevant, Darcy M. Bullock

Purdue Road School

Detector occupancy is commonly used to measure traffic signal performance. Despite improvements in controller computational power, there have been relatively few innovations in occupancy-based performance measures or integration with other data. This paper introduces and demonstrates the use of graphical performance measures based on detector occupancy ratios to verify potential split failures and other signal timing shortcomings reported to practitioners by the public. The proposed performance measures combine detector occupancy during the green phase, detector occupancy during the first five seconds of the red phase, and phase termination cause (gap out or force off). These are summarized by time of …
