Soft topological lattice wheels

no code implementations23 Dec 2020 William Zunker, Stefano Gonella

We investigate the large deformation and extreme load-management capabilities of a soft topologically polarized kagome lattice mapped to a cylindrical domain through the problem of a lattice wheel rolling on an irregular surface.

Improved Support Recovery Guarantees for the Group Lasso With Applications to Structural Health Monitoring

no code implementations29 Aug 2017 Mojtaba Kadkhodaie Elyaderani, Swayambhoo Jain, Jeffrey Druce, Stefano Gonella, Jarvis Haupt

This paper considers the problem of estimating an unknown high dimensional signal from noisy linear measurements, {when} the signal is assumed to possess a \emph{group-sparse} structure in a {known,} fixed dictionary.

Noisy Matrix Completion under Sparse Factor Models

no code implementations2 Nov 2014 Akshay Soni, Swayambhoo Jain, Jarvis Haupt, Stefano Gonella

This paper examines a general class of noisy matrix completion tasks where the goal is to estimate a matrix from observations obtained at a subset of its entries, each of which is subject to random noise or corruption.

Anomaly-Sensitive Dictionary Learning for Unsupervised Diagnostics of Solid Media

no code implementations11 May 2014 Jeffrey M. Druce, Jarvis D. Haupt, Stefano Gonella

This paper proposes a strategy for the detection and triangulation of structural anomalies in solid media.

Automated Defect Localization via Low Rank Plus Outlier Modeling of Propagating Wavefield Data

no code implementations19 Jul 2013 Stefano Gonella, Jarvis D. Haupt

This work proposes an agnostic inference strategy for material diagnostics, conceived within the context of laser-based non-destructive evaluation methods, which extract information about structural anomalies from the analysis of acoustic wavefields measured on the structure's surface by means of a scanning laser interferometer.
