Oversampling and noise-shaping techniques, such as [delta sigma] modulation, are widely used in analog-to-digital conversion to achieve accuracy that exceeds that of integrated-circuit components. Such converters have an ...

We approach dynamic collision avoidance problem from the perspective of designing collision avoidance systems for unmanned aerial vehicles. Before unmanned aircraft can fly safely in civil airspace, robust airborne collision ...

Microphotonic circuits have been proposed for applications ranging from optical switching and routing to optical logic circuits. However many applications require microphotonic circuits to be polarization independent, a ...

In this thesis, we investigate unsupervised and semi-supervised methods to construct anatomical atlases and segment medical images. We propose an integrated registration and clustering algorithm to compute an anatomical ...
