Data-Driven System Identification of 6-DoF Ship Motion in Waves with Neural Networks
Kevin M. Silva, Kevin J. Maki
Critical evaluation and understanding of ship responses in the ocean is important for not only the design and engineering of future platforms but also the operation and safety of t…
Quantum Oscillations between weakly coupled Bose-Einstein Condensates: Evolution in a Non-degenerate Double Well
John D. Andersen, Srikanth Raghavan, V. M. Kenkre
We discuss coherent atomic oscillations between two weakly coupled Bose-Einstein condensates that are energetically different. The weak link is notionally provided by a laser barri…
An open-endcap blade trap for radial-2D ion crystals
Yuanheng Xie, Jiafeng Cui, Marissa D'Onofrio +3
We present the design and experimental demonstration of an open-endcap radio frequency trap to confine ion crystals in the radial-two dimensional (2D) structural phase. The central…
Unconditionally energy stable and first-order accurate numerical schemes for the heat equation with uncertain temperature-dependent conductivity
J. A. Fiordilino, M. Winger
In this paper, we present first-order accurate numerical methods for solution of the heat equation with uncertain temperature-dependent thermal conductivity. Each algorithm yields…
3-phonon scattering pathways for vibrational energy transfer in crystalline RDX
Gaurav Kumar, Francis G. VanGessel, Lynn B. Munday +1
A long-held belief is that shock energy induces initiation of an energetic material through an indirect energy up-pumping mechanism involving phonon scattering through doorway mode…
Faster Convergence in Deep-Predictive-Coding Networks to Learn Deeper Representations
Isaac J. Sledge, Jose C. Principe
Deep-predictive-coding networks (DPCNs) are hierarchical, generative models. They rely on feed-forward and feed-back connections to modulate latent feature representations of stimu…
