Experimental quantification of 3D deformations in sensitive clay during stress-probing
Unique four-dimensional (4D) deformation data are collected during drained triaxial tests on intact specimens of a natural sensitive clay. This requires the development of a miniature triaxial cell for advanced stress path testing, specifically designed fo ...
ICE PUBLISHING2022Charge fluctuations from molecular simulations in the constant-potential ensemble
Sara Bonella, Alessandro Coretti
We revisit the statistical mechanics of charge fluctuations in capacitors. In constant-potential classical molecular simulations, the atomic charges of electrode atoms are treated as additional degrees of freedom which evolve in time so as to satisfy the c ...
2020On the Discreteness of Transmission Eigenvalues for the Maxwell Equations
In this paper, we establish the discreteness of transmission eigenvalues for Maxwell's equations. More precisely, we show that the spectrum of the transmission eigenvalue problem is discrete, if the electromagnetic parameters $\eps, , \mu, , \heps, , \h ...
2020Patching And Weak Approximation In Isometry Groups
Let R be a semilocal principal ideal domain. Two algebraic objects over R in which scalar extension makes sense (e.g. quadratic spaces) are said to be of the same genus if they become isomorphic after extending scalars to all completions of R and its fract ...
Amer Mathematical Soc2017Algebraic and topological methods in combinatorics
The present thesis deals with problems arising from discrete mathematics, whose proofs make use of tools from algebraic geometry and topology. The thesis is based on four papers that I have co-authored, three of which have been published in journals, and o ...
EPFL2017A feasible-side globally convergent modifier-adaptation scheme
Dominique Bonvin, Timm Faulwasser, Alejandro Gabriel Marchetti
In the context of static real-time optimization (RTO) of uncertain plants, the standard modifier-adaptation scheme consists in adding first-order correction terms to the cost and constraint functions of a model based optimization problem. If the algorithm ...
Elsevier Sci Ltd2017On some algebraic and extremal problems in discrete geometry
Seyed Hossein Nassajianmojarrad
In the present thesis, we delve into different extremal and algebraic problems arising from combinatorial geometry. Specifically, we consider the following problems. For any integer , we define to be the minimum positive integer such that an ...
EPFL2017Distinct Values Of Bilinear Forms On Algebraic Curves
Frank de Zeeuw, Adrian Claudiu Valculescu
Let B-M : C x C -> C be a bilinear form B-M(p, q) - p(T)Mq, with an invertible matrix M is an element of C-2x2. We prove that any finite set S contained in an irreducible algebraic curve C of degree d in C determines Omega(d)(vertical bar S vertical bar(4/ ...
