An ALE-based numerical technique for modeling sedimentary basin evolution featuring layer deformations and faults

Alfio Quarteroni, Adelmo Cristiano Innocenza Malossi, Andrea Villa

In this paper we present a numerical tool to simulate dynamics of stratified sedimentary basins, i.e. depressions on the Earth’s surface filled by sediments. The basins are usually complicated by crustal deformations and faulting of the sediments. The bala ...

Three-Dimensional Writing of Conducting Polymer Nanowire Arrays by Meniscus-Guided Polymerization

Giorgio Margaritondo

Accurate and versatile three-dimensional writing of individually controlled conducting polymer nanodevices forming dense arrays is demonstrated by guiding a monomer meniscus in pulling a micropipette during oxidative polymerization. We specifically demonst ...

Hall effect sensors performance investigation using three-dimensional simulations

Maher Kayal, Jean-Michel Sallese, Maria-Alexandra Paun

Several Hall effect sensors were modeled and evaluated regarding the Hall voltage and sensitivity using 3D physical simulations. For accurate results the numerical offset and its temperature drift were analyzed. The versatility of the simulation allows var ...

Automated Vulnerability Discovery in Distributed Systems

Rachid Guerraoui, George Candea, Radu Banabic

In this paper we present a technique for automatically assessing the amount of damage a small number of participant nodes can inﬂict on the overall performance of a large distributed system. We propose a feedback-driven tool that synthesizes malicious node ...

Swirl Jet and Crossflow Interaction at Low Velocity Ratios and Incompressible Flows

Peter Ott, Alexandros Terzis

Swirl jets in crosflow are investigated experimentally and numerically. The main difference with non-swirl cases is an asymmetry of the dominant kidney vortex and a slight distortion of the jet trace downstream of the injection hole. Jet rotation, at relat ...
