Robust mass lumping and outlier removal strategies in isogeometric analysis
Annalisa Buffa, Espen Sande, Yannis Dirk Voet
Mass lumping techniques are commonly employed in explicit time integration schemes for problems in structural dynamics and both avoid solving costly linear systems with the consistent mass matrix and increase the critical time step. In isogeometric analysi ...
2024Pseudo-Three-Dimensional Analytical Model of Linear Induction Motors for High-Speed Applications
Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti
Literature on linear induction motors (LIMs) has proposed several approaches to model the behavior of such devices for different applications. In terms of accuracy and fidelity, field analysis-based models are the most relevant. Closed-form or numerical so ...
2024Transcapacitances Modeling in ultra-thin gate-all-around junctionless nanowire FETs, including 2D quantum confinement
In this work, we propose an analytical model for the intrinsic transcapacitances in ultra-thin gate-all-around junctionless nanowire field effect transistors in the presence of confined energy states of electrons. The validity of the developed model is con ...
PERGAMON-ELSEVIER SCIENCE LTD2023TCB-spline-based isogeometric analysis method with high-quality parameterizations
Isogeometric analysis (IGA) was introduced to integrate methods for analysis and computer-aided design (CAD) into a unified process. High-quality parameterization of a physical domain plays a crucial role in IGA. However, obtaining high-quality parameteriz ...
ELSEVIER SCIENCE SA2022Numerical Studies of Brillouin-induced Polarization Pulling of Probe and Pump in Weakly-Birefringent Optical fibers with Applications to BOTDA
Luc Thévenaz, Marcelo Alfonso Soto Hernandez
Numerical solution of the involved governing equations confirm that the commonly used two orthogonal sets of gain- and loss-probes in BOTDA, differently affect the evolution of the pump state-of- polarization, thereby potentially compromising the minimizat ...
Optica Publishing Group2022Microscopic interplay of temperature and disorder of a one-dimensional elastic interface
Elisabeth Agoritsas, Thierry Giamarchi
Elastic interfaces display scale-invariant geometrical fluctuations at sufficiently large lengthscales. Their asymptotic static roughness then follows a power-law behavior, whose associated exponent provides a robust signature of the universality class to ...
2022Physics-informed neural networks for diffraction tomography
Demetri Psaltis, Carlo Gigli, Amirhossein Saba Shirvan, Ahmed Ayoub
We propose a physics-informed neural network (PINN) as the forward model for tomographic reconstructions of biological samples. We demonstrate that by training this network with the Helmholtz equation as a physical loss, we can predict the scattered field ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2022Subharmonic parametric instability in nearly brimful circular cylinders: a weakly nonlinear analysis
François Gallaire, Alessandro Bongarzone, Francesco Viola
In labscale Faraday experiments, meniscus waves respond harmonically to small-amplitude forcing without threshold, hence potentially cloaking the instability onset of parametric waves. Their suppression can be achieved by imposing a contact line pinned at ...
CAMBRIDGE UNIV PRESS2022Contact.engineering-Create, analyze and publish digital surface twins from topography measurements across many scales
The optimization of surface finish to improve performance, such as adhesion, friction, wear, fatigue life, or interfacial transport, occurs largely through trial and error, despite significant advancements in the relevant science. There are three central c ...
IOP Publishing Ltd2022Limiting the impact of supply chain disruptions in the face of distributional uncertainty in demand
Ralf Seifert, Anna Timonina-Farkas, René Yves Glogg
Service-level requirements play a crucial role in eliminating stock-outs in a production pipeline. However, delivering a specific service level can become an unattainable goal given the various uncertainties influencing both the production pipeline and cus ...
