Frequency domain data-driven robust and optimal control
The goal of this thesis is to propose pragmatic solutions to real challenges faced in the industry. The scope of this thesis encompasses two subjects: frequency-based structured controller synthesis for linear time-invariant (LTI) systems on one side, and ...
EPFL2024Correlation of powers of Hüsler-Reiss vectors and Brown-Resnick fields, and application to insured wind losses
H & uuml;sler-Reiss vectors and Brown-Resnick fields are popular models in multivariate and spatial extreme-value theory, respectively, and are widely used in applications. We provide analytical formulas for the correlation between powers of the components ...
Springer2024Intrinsic-Strain Engineering by Dislocation Imprint in Bulk Ferroelectrics
Dragan Damjanovic, Fangping Zhuo
We report an intrinsic strain engineering, akin to thin filmlike approaches, via irreversible hightemperature plastic deformation of a tetragonal ferroelectric single-crystal BaTiO3. Dislocations wellaligned along the [001] axis and associated strain field ...
AMER PHYSICAL SOC2023Covalent bonded bilayers from germanene and stanene with topological giant capacitance effects
The discovery of twisted bilayer graphene with tunable superconductivity has diverted great focus at the world of twisted van der Waals heterostructures. Here we propose a paradigm for bilayer materials, where covalent bonding replaces the van der Waals in ...
NATURE PORTFOLIO2023An Inverse-Filter-Based Method to Locate Partial Discharge Sources in Power Transformers
Marcos Rubinstein, Hamidreza Karami
Partial discharge (PD) occurrence in power transformers can lead to irreparable damage to the power network. In this paper, the inverse filter (IF) method to localize PDs in power transformers is proposed. To the best of the authors’ knowledge, this is the ...
2022A convex set of robust D—stabilizing controllers using Cauchy's argument principle
Alireza Karimi, Philippe Louis Schuchert
A new approach is presented to obtain a convex set of robust D—stabilizing fixed structure controllers, relying on Cauchy's argument principle. A convex set of D—stabilizing controllers around an initial D—stabilizing controller for a multi-model set is re ...
Elsevier2022Prospects for B-c(+) -> tau(+)nu(tau) at FCC-ee
Clement Helsens, Donal Patrick Hill, Marie Hartmann
This paper presents the prospects for a precise measurement of the branching fraction of the leptonic B-c(+) -> tau(+)nu(tau) decay at the Future Circular Collider (FCC-ee) running at the Z-pole. A detailed description of the simulation and analysis framew ...
SPRINGER2021Is planning still political? The politicization of high-speed rail in Spain (1986–2016)
Post-political debate has stimulated a vigorous research agenda about the role of politics in regional and urban planning. It warns of a depoliticization process leading to the emergence of a consensual social order and the retreat of the properly politica ...
2021Generalized approximate survey propagation for high-dimensional estimation*
In generalized linear estimation (GLE) problems, we seek to estimate a signal that is observed through a linear transform followed by a component-wise, possibly nonlinear and noisy, channel. In the Bayesian optimal setting, generalized approximate message ...
IOP PUBLISHING LTD2020The additive hazard estimator is consistent for continuous-time marginal structural models
Mats Julius Stensrud, Pal Christie Ryalen
Marginal structural models (MSMs) allow for causal analysis of longitudinal data. The standard MSM is based on discrete time models, but the continuous-time MSM is a conceptually appealing alternative for survival analysis. In applied analyses, it is often ...
