BPS invariants from p-adic integrals
Dimitri Stelio Wyss, Francesca Carocci, Giulio Orecchia
We define p-adic BPS or pBPS invariants for moduli spaces M-beta,M-chi of one-dimensional sheaves on del Pezzo and K3 surfaces by means of integration over a non-archimedean local field F. Our definition relies on a canonical measure mu can on the F-analyt ...
Cambridge Univ Press2024Double Quasi-Poisson Algebras are Pre-Calabi-Yau
In this article, we prove that double quasi-Poisson algebras, which are noncommutative analogues of quasi-Poisson manifolds, naturally give rise to pre-Calabi-Yau algebras. This extends one of the main results in [11], where a correspondence between certai ...
2022Bragg edge tomography characterization of additively manufactured 316L steel
Roland Logé, Christian Leinenbach, Efthymios Polatidis, Markus Strobl, Nikola Kalentics
In this work we perform a neutron Bragg edge tomography of stainless steel 316L additive manufacturing samples, one as built via standard laser powder bed fusion, and one using the novel three-dimensional (3D) laser shock peening technique. First, we consi ...
AMER PHYSICAL SOC2022Model-based 3D Face Reconstruction
Christophe René Joseph Ecabert
The human face plays an essential role in social interactions as it brings information about someone's identity, state of mind, or mood. People are, by nature, very good at catching this non-spoken information. Therefore, scientists have been interested in ...
EPFL2021Coordinate-Descent Diffusion Learning by Networked Agents
Ali H. Sayed, Bicheng Ying, Chengcheng Wang
This paper examines the mean-square error performance of diffusion stochastic algorithms under a generalized coordinate-descent scheme. In this setting, the adaptation step by each agent is limited to a random subset of the coordinates of its stochastic gr ...

This work examines the mean-square error performance of diffusion stochastic algorithms under a generalized coordinate-descent scheme. In this setting, the adaptation step by each agent is limited to a random subset of the coordinates of its stochastic gra ...
2017Algorithms for reconstructing geometries from echoes
We have recently witnessed the appearance of algorithms that can reconstruct a room’s geometry from echoes, as well as algorithms that use echoes to localize many microphones. This project will consist in implementing a framework for microphone localizatio ...
2016Integration of outdoor human comfort in a building energy simulation database using CityGML Energy Ade
Jean-Louis Scartezzini, Jérôme Henri Kämpf, Dasaraden Mauree, Silvia Coccolo
Handling data needed by Building Energy Simulation (BES) tools can be a tedious task, especially at the urban scale. Besides BES, users often have different needs (building energy use, human comfort, integration of renewables, urban planning…) in mind when ...
vdf Hochschulverlag AG ETH Zurich2016Algorithmic aspects of sums of Hermitian squares of noncommutative polynomials
This paper presents an algorithm and its implementation in the software package NCSOStools for finding sums of Hermitian squares and commutators decompositions for polynomials in noncommuting variables. The algorithm is based on noncommutative analogs of t ...
Springer2013Synthesizing Glue Operators from Glue Constraints for the Construction of Component-Based Systems
We study glue operators used in component-based frameworks to obtain systems as the composition of atomic components described as labeled transition systems (LTS). Glue operators map tuples of LTS into LTS. They restrict the behavior of their arguments by ...
