ANC of UAS Rotor Noise using Virtual Error Sensors
… active noise control (ANC) systems rely on a physical sensor to measure the error signal at the desired location of attenuation. The error signal is then used to update an adaptive controller, which ultimately attenuates the measured response. However, it is not always practical to use …

Robust distribution sensor network localization with noisy range measurements
… linear-time algorithm for localizing sensor network nodes in the presence of range measurement noise and demonstrates the algorithm on a physical network. We introduce the probabilistic notion of robust quadrilaterals as a way to avoid flip ambiguities that otherwise corrupt …

Non-Invasive Vision-Based Measurement of Hand Kinematics and Interaction
… hand behaves during interaction tasks. Study of physical interaction requires measurement of hand kinematics and interaction forces. Unfortunately, current methods involve cumbersome sensors or external forces that inherently change the way that the subject behaves. In order to avoid these …
