Optimization of multi-group energy structures for diffusion analyses of sodium-cooled fast reactors assisted by simulated annealing - Part I: Methodology demonstration
This study presents an approach to the selection of optimal energy group structures for multi-group nodal diffusion analyses of Sodium-cooled Fast Reactor cores. The goal is to speed up calculations, particularly in transient calculations, while maintainin ...
2021A Computational Method for Identifying the Optimum Buffer Size in the Era of Zero Defect Manufacturing
Decreasing defects, waste time, meeting customer demand and being adaptable are the goals of a Zero Defect Manufacturing (ZDM) strategy. Scheduling is an important tool to perform that. It should take in account buffer size allocation. In this study, a met ...
SPRINGER INTERNATIONAL PUBLISHING AG2020Vulnérabilité sismique à grande échelle de la ville de Lausanne
The assessment of the risk maps for the seismic vulnerability at large scale is based on the vulnerability of each building. In order to determine these vulnerabilities, it is first required to assign to each building its construction class. The constructi ...
2020Benchmarking of the plane-to-plane metric
Touradj Ebrahimi, Evangelos Alexiou
In this report we benchmark the plane-to-plane objective quality metric. This is, a metric that measures the angular similarity of tangent planes between two point cloud models and relies on normal vectors that are carried with associated pairs of points. ...
2020Wasserstein Distributionally Robust Learning
Many decision problems in science, engineering, and economics are affected by uncertainty, which is typically modeled by a random variable governed by an unknown probability distribution. For many practical applications, the probability distribution is onl ...
EPFL2020Heterogeneous Target Assignment to Robotic Fiber Positioner Systems
Denis Gillet, Jean-Paul Richard Kneib, Matin Macktoobian
The target assignment methods applied to robotic fiber positioners are only applicable to homogeneous sets of targets to be observed. However, different batches of robotic fiber positioners available at the focal plane of a telescope can be simultaneously ...
IEEE2019Accuracy Assessment of Nonlinear Seismic Displacement Demand Predicted by Simplified Methods for the Plateau Range of Design Response Spectra
Pierino Lestuzzi, Lorenzo Diana
The non-linear seismic displacement demand prediction for low-period structures, i.e. with an initial fundamental period situated in the plateau of design response spectra is studied. In Eurocode 8, the computation of seismic displacement demands is essent ...
2019A Data-Driven Frequency-Domain Approach for Robust Controller Design via Convex Optimization
The objective of this dissertation is to develop data-driven frequency-domain methods for designing robust controllers through the use of convex optimization algorithms. Many of today's industrial processes are becoming more complex, and modeling accurate ...
EPFL2018Global Identification of Kinetic Parameters via the Extent-based Incremental Approach
Dominique Bonvin, Julien Léo Billeter, Diogo Filipe Mateus Rodrigues
The identification of reaction kinetics represents the main challenge in building models for reaction systems. The identification task can be performed via either simultaneous model identification (SMI) or incremental model identification (IMI), the latter ...
2017Lower Bounds on Regret for Noisy Gaussian Process Bandit Optimization
Volkan Cevher, Jonathan Mark Scarlett, Ilija Bogunovic
In this paper, we consider the problem of sequentially optimizing a black-box function based on noisy samples and bandit feedback. We assume that is smooth in the sense of having a bounded norm in some reproducing kernel Hilbert space (RKHS), yield ...
