Data-driven Identification of Parametric Governing Equations of Dynamical Systems Using the Signed Cumulative Distribution Transform
Abu Hasnat Mohammad Rubaiyat, Duy H. Thai, Jonathan M. Nichols +6
This paper presents a novel data-driven approach to identify partial differential equation (PDE) parameters of a dynamical system. Specifically, we adopt a mathematical "transport"…
Architected Lattices with Adaptive Energy Absorption
Yifan Wang, Brian Ramirez, Kalind Carpenter +3
Energy absorbing materials, like foams used in protective equipment, are able to undergo large deformations under low stresses, reducing the incoming stress wave below an injury or…
Shape-morphing architected sheets with non-periodic cut patterns
Paolo Celli, Connor McMahan, Brian Ramirez +5
We investigate the out-of-plane shape morphing capability of single-material elastic sheets with architected cut patterns that result in arrays of tiles connected by flexible hinge…
A camera for single pixel acoustic compressive sensing in air
Jeffrey S. Rogers, Charles A. Rohde, Matthew D. Guild +3
Acoustic imaging typically relies on large sensor arrays that can be electronically complex and often have large data storage requirements to process element level data. Recently,…
Superresolution through the topological shaping of sound with an acoustic vortex wave antenna
Matthew D. Guild, Christina J. Naify, Theodore P. Martin +2
In this paper, we demonstrate far-field acoustic superresolution using shaped acoustic vortices. Compared with previously proposed near-field methods of acoustic superresolution, i…
Generation of topologically diverse acoustic vortex beams using a compact metamaterial aperture
Christina J. Naify, Charles A Rohde, Theodore P. Martin +3
Vortex waves, which carry orbital angular momentum, have found use in a range of fields from quantum communications to particle manipulation. Due to their widespread influence, sig…
Transparent gradient index lens for underwater sound based on phase advance
Theodore P. Martin, Christina J. Naify, Elizabeth A. Skerritt +6
Spatial gradients in refractive index have been used extensively in acoustic metamaterial applications to control wave propagation through phase delay. This study reports the desig…
Highly-anisotropic elements for acoustic pentamode applications
Christopher N. Layman, Christina J. Naify, Theodore P. Martin +2
Pentamode metamaterials are a class of acoustic metafluids that are characterized by a divergence free modified stress tensor. Such materials have an unconventional anisotropic sti…
