Speaker Independent Speech Inversion System
Published Thursday, October 17, 2019BackgroundSpeech inversion is the process of mapping acoustic signals into articulatory parameters. This is a well-known ill-posed problem and the addition of individual speaker differences make it even harder to solve. Normalizing the speaker differences is essential to effectively using multi-speaker articulatory data for training a...

An Easy-to-Deploy Temporal Thermographic Data Collection and Analysis System
Published Thursday, May 3, 2018Buildings in the United States consume a significant amount of energy and release an increasing amount of CO2. Accordingly, tools and techniques have been developed to determine where energy efficiency in buildings can be improved. One such technique is thermography, where auditors determine energy inefficiency using a thermal camera that shows...

Risk-Based Path Optimization
Published Wednesday, February 28, 2018Operating unmanned aerial vehicles (UAVs) over inhabited areas requires mitigating the risk to persons on the ground. Because the risk depends upon the flight path, UAV operators need approaches that can find low-risk flight paths between the mission’s start and finish points. Since the flight paths with the lowest risk could be excessively long...
