Generalizing Bulk-Synchronous Parallel Processing for Data Science: From Data to Threads and Agent-Based Simulations
Agent-based simulations have been widely applied in many disciplines, by scientists and engineers alike. Scientists use agent-based simulations to tackle global problems, including alleviating poverty, reducing violence, and predicting the impact of pandem ...
EPFL2023High-order geometric integrators for nonadiabatic molecular quantum dynamics and their applications to explore conical intersections
Accurate simulations of molecular quantum dynamics are crucial for understanding numerous natural processes and experimental results. Yet, such high-accuracy simulations are challenging even for relatively simple systems where the Born-Oppenheimer approxim ...
EPFL2022Increasing Superstructure Optimization Capacity Through Self-Learning Surrogate Models
François Maréchal, Ivan Daniel Kantor, Julia Granacher
Simulation-based optimization models are widely applied to find optimal operating conditions of processes. Often, computational challenges arise from model complexity, making the generation of reliable design solutions difficult. We propose an algorithm fo ...
2021Reduced-order Models for Simulating Coupled Geometric Instabilities in Steel Beam-columns Under Inelastic Cyclic Straining
Numerical models that can simulate coupled geometric instabilities in steel beam-columns are required for the seismic assessment of certain steel moment-resisting frames. Reliably simulating coupled instabilities requires that the steel material is precise ...
EPFL2021Design of the First HTS Single-Coil Demonstrator of GaToroid Toroidal Gantry for Hadron Therapy
Luca Bottura, Enrico Felcini, Jérôme Harray, Bertrand Dutoit
The design and construction of compact and lightweight gantries for hadron therapy are essential steps toward wider accessibility to this cancer treatment. The use of a high-field steady-state toroidal gantry, i.e., GaToroid, represents an attractive alter ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Optimization of Electrode Dimensions in a Piezoelectrically Actuated Trampoline
This report discusses the use of COMSOL Multiphysics to simulate the behaviour of piezoelectrically actuated MEMS resonators called trampolines. After building the proper geometry and optimising the mesh, a series of simulations will be done to study the m ...
2020Out-of-plane instability of thin reinforced concrete walls under seismic loading
Out of plane instability of reinforced concrete walls is a failure mechanism observed rather recently following the earthquakes in Chile (2010) and New Zealand (2011). Global out of plane instability is a phenomenon that may occur in thin walls, subjected ...
EPFL2018CO2 capture in amine solutions: modelling and simulations with non-empirical methods
Wanda Andreoni, Fabio Pietrucci
Absorption in aqueous amine solutions is the most advanced technology for the capture of CO2, although suffering from drawbacks that do not allow exploitation on large scale. The search for optimum solvents has been pursued with empirical methods and has a ...
Iop Publishing Ltd2016Simulation and optimization: a short review
This review discusses some issues related to the use of simulation in transportation analysis. Potential pitfalls are identified and discussed. An overview of some methods relevant to the use of an advanced simulation tool in an optimization context is als ...
Pergamon-Elsevier Science Ltd2015SOI Hall cells design selection using three-dimensional physical simulations
Maria-Alexandra Paun, Florin Udrea
The main characteristics of Hall Effect Sensors, based on "silicon-on-insulator" (SOI) structure in the ideal design features, are evaluated by performing three-dimensional physical simulations. A particular Hall shape reproducing an XFAB SOI XI10 integrat ...
