Dual chirped microcomb based parallel ranging at megapixel-line rates
Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Anton Lukashchuk
Photonic integrated systems can be harnessed for fast and efficient optical telecommunication and metrology technologies. Here the authors develop a dual-soliton microcomb technique for massively parallel coherent laser ranging that requires only a single ...
NATURE PORTFOLIO2022pyFFS: A Python Library for Fast Fourier Series Computation and Interpolation with GPU Acceleration
Martin Vetterli, Paul Hurley, Eric Bezzam, Sepand Kashani, Matthieu Martin Jean-André Simeoni
Fourier transforms are an often necessary component in many computational tasks, and can be computed efficiently through the fast Fourier transform (FFT) algorithm. However, many applications involve an underlying continuous signal, and a more natural choi ...
2022Neural Set Function Extensions: Learning with Discrete Functions in High Dimensions
Andreas Loukas, Nikolaos Karalias
Integrating functions on discrete domains into neural networks is key to developing their capability to reason about discrete objects. But, discrete domains are (I) not naturally amenable to gradient-based optimization, and (II) incompatible with deep lear ...

A method for performing synchrophasor estimation of an input signal , whereby the input signal is a sinusoidal power system voltage or current signal , comprising: a. Periodic ampling of a continuous time - domain waveform, consisting of a power system vol ...
2021Versatile shaping of optical frequency combs and applications
Optical frequency combs are a series of phase-locked and equidistant laser lines in the spectral domain. In the time domain, they correspond to periodic pulse trains by the Fourier relation. The ability to shape optical combs and pulse trains is pivotal to ...
EPFL2021Discrete Time Analysis of Phase Detector Linear Range Extension in Sub-Sampling PLL
The discrete time analysis of the phase detector linear range extension in the first and the second order sub sampling phase-locked loop (SSPLL) is presented. The aim is to understand how much the stability and the pull-in range are affected by the linear ...
IEEE2020Discrete Time Analysis of Phase Detector Timing Nonidealities in Type-I Sub-Sampling PLL
The analysis of the effect of sub-sampling phase detector (SSPD) timing nonidealities on Type-I sub-sampling phase-locked loop (SSPLL) is presented. The nonidealities considered are the delay between the complementary sampling clocks and the propagation de ...
IEEE2020Detection Under One-Bit Messaging Over Adaptive Networks
This paper studies the operation of multi-agent networks engaged in binary decision tasks, and derives performance expressions and performance operating curves under challenging conditions with some revealing insights. One of the main challenges in the ana ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019A Fourier-accelerated volume integral method for elastoplastic contact
Jean-François Molinari, Guillaume Anciaux, Lucas Henri Galilée Frérot
The contact of solids with rough surfaces plays a fundamental role in physical phenomena such as friction, wear, sealing, and thermal transfer. However, its simulation is a challenging problem due to surface asperities covering a wide range of length-scale ...
2019Efficiently Learning Fourier Sparse Set Functions
Andreas Krause, Mikhail Kapralov, Amir Zandieh
Learning set functions is a key challenge arising in many domains, ranging from sketching graphs to black-box optimization with discrete parameters. In this paper we consider the problem of efficiently learning set functions that are defined over a ground ...
