Analytic adjoint solution for incompressible potential flows
Carlos Lozano, Jorge Ponsin
We obtain the analytic adjoint solution for two-dimensional (2D) incompressible potential flow for a cost function measuring aerodynamic force using the connection of the adjoint a…
Embedding Differential Dynamic Logic in PVS
J. Tanner Slagel, Mariano Moscato, Lauren White +3
Differential dynamic logic (dL) is a formal framework for specifying and reasoning about hybrid systems, i.e., dynamical systems that exhibit both continuous and discrete behaviors…
An Efficient Quadratic Interpolation Scheme for a Third-Order Cell-Centered Finite-Volume Method on Tetrahedral Grids
Hiroaki Nishikawa, Jeffery A. White
In this paper, we propose an efficient quadratic interpolation formula utilizing solution gradients computed and stored at nodes and demonstrate its application to a third-order ce…
Active metasurfaces: lighting the path to commercial success
Tian Gu, Hyun Jung Kim, Clara Rivero-Baleine +1
Active optical metasurfaces are rapidly emerging as a major frontier in photonics research, development, and commercialization. They promise compact, light-weight, and energy-effic…
Impact angle control of local intense d/d variations during shock-induced substorms
Denny M. Oliveira, James M. Weygand, Eftyhia Zesta +7
The impact of interplanetary shocks on the magnetosphere can trigger magnetic substorms that intensify auroral electrojet currents. These currents enhance ground magnetic field per…
Implicit gradients based conservative numerical scheme for compressible flows
Amareshwara Sainadh Chamarthi, Natan Hoffmann, Hiroaki Nishikawa +1
This paper introduces a novel approach to compute the numerical fluxes at the cell boundaries for a cell-centered conservative numerical scheme. Explicit gradients used in deriving…
