Functional-Basis Analysis of Non-Stationary Signals in Modern Power Grids: Theory and Implementation in Embedded Systems
Situational awareness strategies are essential for the reliable and secure operation of the electric power grid which represents critical infrastructure in modern society. With the rise of converter-interfaced renewable generation and the consequent shift ...
EPFL2024Gyrokinetic simulation of short wavelength ion temperature gradient instabilities in the ADITYA-U tokamak
Laurent Villard, Emmanuel Lanti
In this work, linear and nonlinear collisionless electrostatic simulation studies of the standard and short wavelength ion temperature gradient mode (SWITG) for experimental profiles and parameters of ADITYA-U tokamak are performed using the linear global ...
IOP Publishing Ltd2023Synaptic transistors with aluminum oxide dielectrics enabling full audio frequency range signal processing
Danick Briand, Alessio Mancinelli
The rapid evolution of the neuromorphic computing stimulates the search for novel brain-inspired electronic devices. Synaptic transistors are three-terminal devices that can mimic the chemical synapses while consuming low power, whereby an insulating diele ...
2020Dynamic response of a compressible binary fluid mixture
Binary fluids are present in a wide variety of systems at microscales, such as microfluidic devices containing drops, fluids with air bubbles trapped in them, and devices designed to mix fluids or to make two fluid substances react. Microfluidics devices a ...
2020Measurement of Displacement and Its Derivatives from a Phase Fringe Pattern
Pramod Rastogi, Rishikesh Dilip Kulkarni
Noting the fact that the phase and phase derivatives carry the information on the mechanical deformation in optical interferometric measurements techniques, we propose a noise robust fringe analysis technique for the simultaneous estimation of unwrapped ph ...
SPRINGER INTERNATIONAL PUBLISHING AG2019Beyond Phasors: Modeling of Power System Signals Using the Hilbert Transform
Mario Paolone, Asja Derviskadic, Guglielmo Frigo
Modern power systems are at risk of largely reducing the inertia of generation assets and prone to experience extreme dynamics. The consequence is that, during electromechanical transients triggered by large contingencies, transmission of electrical power ...
2019Free standing and solidly mounted Lamb wave resonators based on Al0.85Sc0.15N thin film
Paul Muralt, Mohammad Fazel Parsapour Kolour, Vladimir Pashchenko
Lamb wave microresonators with wavelengths of 5-8m, vibrating in the S0 mode, and having 75 electrode pairs were fabricated and characterized. The results were compared to theoretical predictions obtained by finite element simulation. The active material w ...
AMER INST PHYSICS2019Linear collisionless dynamics of the GAM with kinetic electrons: Comparison simulations/theory
Barely trapped and passing electrons have been recently predicted to strongly enhance the damping rate of Geodesic Acoustic Modes (GAMs) in tokamak plasmas, while keeping their real frequency almost unchanged as compared to the case with adiabatic electron ...
AMER INST PHYSICS2019Pattern Recognition in Non-uniformly sampled electrocardiogram signal for wearable sensors
In this thesis, we explore 3 main topics: non-uniform (in time) sub-sampling, QRS detection in an event-based sub-sampled ECG (electrocardiogram) and implementation on a low-power MCU (Micro Controller Unit). The main idea behind this work is to reduce the ...
2019Improved off‐resonance phase behavior using a phase‐inverted adiabatic half‐passage pulse for 13 C MRS in humans at 7 T
Rolf Gruetter, Lijing Xin, Daniel Gallichan, Eulalia Serés Roig
In vivo (13) C MRS at high field benefits from an improved SNR and spectral resolution especially when using surface coils in combination with adiabatic pulses, such as the adiabatic half-passage (AHP) pulse for (13) C excitation. However, the excitation p ...
