Combination of frequency shift and impedance-based method for robust temperature sensing using piezoceramic devices for shm
Emmanuel Lizé, Charles Hudin, Nicolas Guenard +3
The influence of temperature is a major problem in Structural Health Monitoring diagnosis using guided waves. In this article, two methods for temperature compensation are used to…
Thresholding gradient methods in Hilbert spaces: support identification and linear convergence
Guillaume Garrigos, Lorenzo Rosasco, Silvia Villa
We study regularized least squares optimization problem in a separable Hilbert space. We show that the iterative soft-thresholding algorithm (ISTA) converges linearly, wit…
On the Progenitor of Binary Neutron Star Merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1095
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and…
GW170608: Observation of a 19-solar-mass Binary Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1101
On June 8, 2017 at 02:01:16.49 UTC, a gravitational-wave signal from the merger of two stellar-mass black holes was observed by the two Advanced LIGO detectors with a network signa…
Wavelet-based regularization of the Galerkin truncated three-dimensional incompressible Euler flows
Marie Farge, Naoya Okamoto, Kai Schneider +1
We present numerical simulations of the three-dimensional Galerkin truncated incompressible Euler equations that we integrate in time while regularizing the solution by applying a…
Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
A. Marciniak, P. Bartczak, T. Müller +40
The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…
