Minisymposia

In addition to the general submission track, WAVES 2017 will feature three special thematic minisymposia.

Nonlinear Waves in Mechanical Metamaterials and Phononic Crystals
Organizers: Dennis Kochmann (kochmann@caltech.edu) and Vincent Tournat (vincent.tournat@univ-lemans.fr)

While linear waves in architected materials systems have been a continued focus of research (including the study of acoustic, phononic, and mechanical metamaterials), the propagation of nonlinear waves in such engineered mechanical systems have remained much less understood. We aim to bring together researchers from mathematics, mechanics, materials science, etc. to discuss the state of the art in nonlinear waves in mechanical metamaterials, phononic crystals, and related systems, including theory, numerical modeling, and experiments.

Gravitational Waves: Sources and Detection
Organizer: Vuk Mandic (mandi009@umn.edu)

Recent first detections of gravitational wave signals have opened new areas of astrophysics and astronomy. Gravitational waves have already enabled observations of events and objects never seen before, and they hold great potential to further develop our understanding of the universe and its constituents. This Minisymposium will focus on different types of gravitational-wave signals that could be produced in astrophysical and cosmological processes, as well as on different techniques to search for and detect such signals with current and future gravitational wave detectors.

Seismic Waves: Uncertainty Quantification in Imaging/Inversion Across Scales
Organizers: Alison Malcolm (amalcolm@mun.ca) and Hejun Zhu (hejun.zhu@utdallas.edu)

Seismic waves are our primary means of sensing the subsurface of the Earth, at scales that range from a few meters to thousands of kilometers. Determining Earth structure from these waves is challenging because of the inherent nonuniqueness of the inverse problem, as well as the size of the associated computational problem. Because of these challenges, relatively little has been done on the assessment of uncertainty in the inverse problem. A pixel-by-pixel estimate of uncertainty is still computationally intractable, as well as difficult to use as a means to convey uncertainty. This mini-symposium focuses on how we can move toward meaningful measures of uncertainty across all scales of seismic imaging.
