Constructing periodic orbits of high-dimensional chaotic systems by an adjoint-based variational method
Tobias Schneider, Sajjad Azimi, Omid Ashtari
Chaotic dynamics in systems ranging from low-dimensional nonlinear differential equations to high-dimensional spatiotemporal systems including fluid turbulence is supported by nonchaotic, exactly recurring time-periodic solutions of the governing equations ...
2022Experimental Investigation of Steel Braces Installed with Intentional Eccentricity Using Gusset Plate Connections
The present paper proposes an improved design of conventional buckling braces (CBBs) by introducing intentional eccentricity along the brace length. The proposed brace is named the Brace with Intentional Eccentricity (BIE). Due to the inherent action momen ...
International Association of Earthquake Engineering2017Experimental Investigation of Bolt-Configured Naturally Buckling Braces with Gusset Plate Connections
The Naturally Buckling Brace (NBB) is a steel brace developed by the writers, which consists of a high-strength and low-yielding steel channel arranged in parallel with an intentional eccentricity along the brace length. The NBB deforms with a novel mechan ...
International Association of Earthquake Engineering2017SATELLITE CONSTELLATION DESIGN FOR THE SOLVE MISSION INVESTIGATING DIURNAL CYCLES OF VEGETATION PHENOMENA
Anton Ivanov, Luzius Gregor Kronig, Sung Wook Paek, Olivier Ladislas Alain de Weck
This paper discusses the problem of finding an optimal satellite constellation for the SOLVE (Satellites Observing Lakes and Vegetation Environments) Mission. A key requirement of this mission is a temporal resolution of several observations per day. A sem ...
2016Improving the quality of filament-impaired images in Kerr media by statistical averaging
Demetri Psaltis, Alexandre Goy
In focusing Kerr media, small- scale filamentation is the major obstacle to imaging at high light intensities. In this article, we experimentally and numerically demonstrate a method based on statistical averaging to reduce the detrimental effects of filam ...
Optical Soc Amer2015Transient perturbation growth in time-dependent mixing layers
Cristobal Manuel Arratia Martinez
We investigate numerically the transient linear growth of three-dimensional (3D) perturbations in a homogeneous time-evolving mixing layer in order to identify which perturbations are optimal in terms of their kinetic energy gain over a finite, predetermin ...
Cambridge University Press2013Edge states for the turbulence transition in the asymptotic suction boundary layer
Tobias Schneider, Tobias Klaus Kreilos
We demonstrate the existence of an exact invariant solution to the Navier-Stokes equations for the asymptotic suction boundary layer. The identified periodic orbit with a very long period of several thousand advective time units is found as a local dynamic ...
Cambridge University Press2013The CORALIE survey for southern extrasolar planets XVI. Discovery of a planetary system around HD 147018 and of two long period and massive planets orbiting HD 171238 and HD 204313
We report the detection of a double planetary system around HD 140718 as well as the discovery of two long period and massive planets orbiting HD 171238 and HD 204313. Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m E ...
2010Venus plus delta f: A bootstrap current calculation module for 3-D configurations
Wilfred Anthony Cooper, Stephan Brunner, Trach-Minh Tran
A new three-dimensional code, VENUS+delta f, for neoclassical transport calculations in nonaxisymmetric toroidal systems is presented. Numerical drift orbits from the original VENUS code and the delta f method developed for tokamak transport calculations a ...
