Model management to support systems engineering workflows using ontology-based knowledge graphs
Arkadiusz Ryś, Lucas Lima, Joeri Exelmans +2
System engineering has been shifting from document-centric to model-based approaches, where assets are becoming more and more digital. Although digitisation conveys several benefit…
Iterative Switching Time Optimization for Mixed-integer Optimal Control Problems
Ramin Abbasi-Esfeden, Wim Van Roy, Jan Swevers
This paper proposes an iterative method to solve Mixed-Integer Optimal Control Problems arising from systems with switched dynamics. The so-called relaxed problem plays a central r…
Continuation strategies to mitigate convergence to low-performing local optima in topology optimization of sound transmission loss
Tom De Weer, Vanessa Cool, Elke Deckers
Dynamic topology optimization problems often suffer from convergence to low-performing local optima. This typically results in stiff designs that do not exploit dynamical phenomena…
Evaluating Competitiveness in UEFA's New Champions League Format
Karel Devriesere, Dries Goossens, Frits Spieksma
Recently, UEFA changed the group stage of its international soccer competitions to an incomplete round robin tournament. Previously, teams were divided into groups, each playing a…
STable AutoCorrelation Integral Estimator (STACIE): Robust and accurate transport properties from molecular dynamics simulations
Gözdenur Toraman, Dieter Fauconnier, Toon Verstraelen
STACIE (STable AutoCorrelation Integral Estimator) is a novel algorithm and Python package that delivers robust, uncertainty-aware estimates of autocorrelation integrals from time-…
Testing Light Unaffiliated Mass Clumps in MACS 0416 on galaxy and galaxy cluster scales using JWST
Marceau Limousin, Derek Perera, Gregor Rihtarsic +2
Light unaffiliated mass clumps (LUMCs), i.e. dark matter (DM) components without any stellar counterparts, have been reported in strong lensing mass reconstructions of MACS 0416, b…
