We introduce an unobtrusive sensor-based control system for human-machine interface to control robotic and rehabilitative devices. The interface is capable of directing assistive robotic devices in response to tongue movement and/or speech without insertion of any device in the vicinity of the oral cavity. The interface is centered on the unique properties(More)
Hong and Ladner (2001) used context-based group testing to implement bit-plane coding for image compression. We extend this technique to video coding, by replacing the quantization and entropy-coding stages, of an H.263 standard video coder, with bit-plane coding. We experiment with ways to improve baseline coder, including different classification schemes(More)
This paper presents the development effort to establish modeling capabilities for launch vehicle liftoff acoustics and ignition transient environment predictions. Peak acoustic loads experienced by the launch vehicle occur during liftoff with strong interaction between the vehicle and the launch facility. Acoustic prediction engineering tools based on(More)
