Optimal Design and Control of Dual Active Bridge DC-DC Converters – Kaushik Basu, EE

by admin | Sep 28, 2021 | Snippets

Dual active bridge isolated DC-DC converters are now widely used in medium and high-power applications such as DC distribution systems, electric vehicle chargers, etc. A design methodology has been developed that minimizes current stress and enables lossless...

Uniqueness of rigid point-cloud registration – Kunal N Chaudhury, EE

by admin | Sep 28, 2021 | Snippets

A necessary and sufficient condition for uniquely registering a system of point clouds (whose positions are known in different coordinate systems) in a global coordinate system [1] has been obtained. This was done by relating the registration problem to the rigidity...

The value of timing information in event-triggered control – Pavankumar Tallapragada, EE

by admin | Sep 28, 2021 | Snippets

This work demonstrates that in event-triggered control, the timing of the events carries implicit information. In particular, we have found necessary and sufficient data rates, under bounded communication delays, for asymptotic stabilization of linear systems with...

Semi-Supervised Cross-Modal Retrieval With Label Prediction – Soma Biswas, EE

by admin | Sep 28, 2021 | Snippets

Cross-modal retrieval with image-text, sketch-image, etc. are gaining increasing importance due to abundance of data from multiple modalities, and applications like e-commerce, security, etc. In [1], we develop a novel approach which utilizes few labeled and remaining...

Deep Unsupervised Speech Representation Learning – Sriram Ganapathy, EE

by admin | Sep 28, 2021 | Snippets

The performance of speech systems is degraded in the presence of noise. The principle of modulation filtering attempts to remove the spectro-temporal modulations that are susceptible to noise. While traditional approaches use modulation filters that are hand-crafted,...
