Scalable constrained optimization
Modern optimization is tasked with handling applications of increasingly large scale, chiefly due to the massive amounts of widely available data and the ever-growing reach of Machine Learning. Consequently, this area of research is under steady pressure t ...
EPFL2024Plug-and-play adaptive surrogate modeling of parametric nonlinear dynamics in frequency domain
Jürg Alexander Schiffmann, Phillip Huwiler, Davide Pradovera
We present an algorithm for constructing efficient surrogate frequency-domain models of (nonlinear) parametric dynamical systems in a non-intrusive way. To capture the dependence of the underlying system on frequency and parameters, our proposed approach c ...
2023Modeling non-covalent interactions in condensed phase
The modeling of non-covalent interactions, solvation effects, and chemical reactions in complex molecular environment is a challenging task. Current state-of-the-art approaches often rely on static computations using implicit solvent models and harmonic ap ...
EPFL2022ADAPT21: Adaptability as a 21st century skill
All life is problem solving. We are most often faced with situations, in which the information that is needed to solve a problem is not immediately obvious and in which things can change quite rapidly. For instance, imagine the software on your smartphone ...
Open Science Framework2021Modeling Supply Chain Disruptions: A Network Flow Approach
Globalization, outsourcing and cost optimization have all contributed to increased supply chain vulnerability, yet our understanding of effective mitigation strategies remains limited. In our research, we study the effects of disruptions on supply chain ne ...
EPFL2021Predictors and predictands of linear response in spatially extended systems
The goal of response theory, in each of its many statistical mechanical formulations, is to predict the perturbed response of a system from the knowledge of the unperturbed state and of the applied perturbation. A new recent angle on the problem focuses on ...
SPRINGER HEIDELBERG2021Measuring causality between collaborative and individual gaze metrics for collaborative problem-solving with intelligent tutoring systems
Kshitij Sharma, Jennifer Kaitlyn Olsen
When students are working collaboratively and communicating verbally in a technology-enhanced environment, the system cannot track what collaboration is happening outside of the technology, making it difficult to fully assess the collaboration of the stude ...
2020Problem structuring to enable innovation in business/IT projects
Gil Regev, Tatiana Porté, Alain Wegmann
In this paper, we present a problem structuring method in business and IT analysis illustrated with an example. The project describes an IT consulting case done for a Swiss medical society faced with a problem of change management and digital transformatio ...
LUT Scientific and Expertise Publications2020MATERIAL POINT METHOD A numerical evaluation for elastic problems
Frozen, the movie, released in 2013, made a big impression on many people: some children were no doubt amazed by the talking snowman, others by the film’s music, the designers were probably more interesed in the reproduction quality of the snow modelled, b ...
2020Experiments in digital publishing: creating a digital compendium
This chapter introduces the readers and users to the goals of the digitally provided index of the compendium Structures of Epic Poetry and the methods used for it. It also expands on the broader applicability of digital methods in view of electronic publis ...
