On constraining the speed of gravitational waves following GW150914

Sergey Sibiryakov, Diego Blas Temino, Mikhail Ivanov

We point out that the observed time delay between the detection of the signal at the Hanford and Livingston LIGO sites from the gravitational wave event GW150914 places an upper bound on the speed of propagation of gravitational waves, c (gw) ae(2) 1.7 in ...

Impact of Grid Asymmetries on the Operation and Capacitive Energy Storage Design of Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

The grid-connected modular multilevel converter (MMC) is very likely to operate under asymmetric grid conditions. Such a converter features several unique characteristics, whichmake its analysis different from other types of power converters in similar cas ...

Experimental assessment of the speed of light perturbation in free-fall absolute gravimeters

Sergey Sibiryakov, Diego Blas Temino

Precision absolute gravity measurements are growing in importance, especially in the context of the new definition of the kilogram. For the case of free fall absolute gravimeters with a Michelson-type interferometer tracking the position of a free falling ...

Fast prediction and evaluation of gravitational waveforms using surrogate models

Jan Sickmann Hesthaven

We propose a solution to the problem of quickly and accurately predicting gravitational waveforms within any given physical model. The method is relevant for both real-time applications and in more traditional scenarios where the generation of waveforms us ...

Exploring red blood cell membrane dynamics with digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Jonas Kühn, Daniel Boss

Digital Holographic Microscopy (DHM) has been used to investigate the spontaneous cell membrane fluctuations (CMF) of the Red Blood Cell. DHM as an interferometric technique is able to accurately provide the wavefront deformation induced by a transparent s ...

Compact Fourier transform spectrometers using FR4 platform

Caglar Ataman

A novel magnetic actuated polymer optical platform is integrated into lamellar grating and Michelson type Fourier transform spectrometers. The proposed advantages of the novel platform over existing approaches, such as MEMS spectrometers, or bulky FTIR sys ...

Several micron-range measurements with sub-nanometric resolution by the use of dual-wavelength digital holography and vertical scanning

Christian Depeursinge, Tristan Colomb, Jonas Kühn

Reflection digital holographic microscopy (DHM) is a very powerful technique allowing measuring topography with a sub-nanometer axial resolution from a single hologram acquisition. But as most of interferometer methods, the vertical range is limited to hal ...

Synchronous and Asynchronous Detection of Ultra-Low Light Levels

Peter Seitz, Christian Lotto

Comprehensive analysis of noise sources in photocharge detectors leads to two novel, compact pixel circuits for ultra-low-noise light detection using optimum bandwidth engineering. A synchronous 4T CMOS image sensor pixel with in-pixel amplification reache ...
