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 ...
EPFL2024Unlikely intersections on the p-adic formal ball
We investigate generalizations along the lines of the Mordell-Lang conjecture of the author's p-adic formal Manin-Mumford results for n-dimensional p-divisible formal groups F. In particular, given a finitely generated subgroup (sic) of F(Q(p)) and a close ...
SPRINGER INT PUBL AG2023Multi-IVE: Privacy Enhancement of Multiple Soft-Biometrics in Face Embeddings
Sébastien Marcel, Hatef Otroshi Shahreza
This study focuses on the protection of soft-biometric attributes related to the demographic information of individuals that can be extracted from compact representations of face images, called embeddings. We consider a state-ofthe-art technology for soft- ...
IEEE COMPUTER SOC2023Invariant Integrals on Topological Groups and Applications
We study a fixed point property for linear actions of discrete groups on weakly complete convex proper cones in locally convex topological vector spaces. We search to understand the class of discrete groups which enjoys this property and we try to generali ...
EPFL2021Image-based analysis of living mammalian cells using label-free 3D refractive index maps reveals new organelle dynamics and dry mass flux
Françoise Gisou van der Goot Grunberg, Christopher Claude Giuseppe Tremblay, Patrick Alain Sandoz
Holo-tomographic microscopy (HTM) is a label-free microscopy method reporting the fine changes of a cell’s refractive indices (RIs) in three dimensions at high spatial and temporal resolution. By combining HTM with epifluorescence, we demonstrate that mamm ...
2019Shape from bandwidth: the 2-D orthogonal projection case
Martin Vetterli, Benjamin Bejar Haro, Adam James Scholefield
Could bandwidth—one of the most classic concepts in signal processing—have a new purpose? In this paper, we investigate the feasibility of using bandwidth to infer shape from a single image. As a first analysis, we limit our attention to orthographic proje ...
Ieee2017Projective transformations of structural equilibrium
Direct methods that transform the geometry of a structure and conserve its static equilibrium are of particular interest for designers. They allow the exploration of alternative solutions at minimum computational cost. While parallel transformations (stret ...
2016Reciprocal diagrams: Innovative applications of past theories
The geometric relationships between a structural configuration and its internal force distribution have not received much attention for nearly hundred years. Directly stemming from the most fundamental principles of statics, the underlying theories were br ...
2016Converting disulfide bridges in native peptides to stable methylene thioacetals
Nicolai Cramer, Christopher Matthew Bandeli Kourra
Disulfide bridges play a crucial role in defining and rigidifying the three-dimensional structure of peptides. However, disulfides are inherently unstable in reducing environments. Consequently, the development of strategies aiming to circumvent these defi ...
