Numerical Steepest Descent for Overlap Integrals of Semiclassical Wavepackets
(2015)Research ReportIn this report we show that classical Gauss quadrature is not adequate for a large class of correlation and overlap integrals originating from quantum mechanics. These integrals are usually highly oscillatory and therefore special methods are necessary for accurate computations. We develop and test a new, highly efficient method based on some recent results about numerical steepest descent to solve the problem stated. Our approach is built ...Report -

Focal Report 5: Using Scenarios to Assess Risks
(2012)CSS Risk and Resilience ReportsThis report aims to shed some light on the interrelationship between (different types of) scenarios and risk assessment by looking more closely at risk management approaches in Denmark, the Netherlands, Germany and the United Kingdom. In turn, it aims to develop a more nuanced understanding of the value and limits of scenarios in risk assessment.Report -
Imaging acoustic obstacles by hypersingular point sources
(2011)Research ReportWe investigate a qualitative method for imaging acoustic obstacles in two and three dimensions by boundary measurements. The imaging scheme makes use of the hypersingular point sources. Rigorous mathematical justification of the imaging method is established, and numerical experiments are presented to illustrate the effectiveness of the proposed imaging scheme.Report -
Optimization Based Autonomous Racing of 1:43 Scale RC Cars
(2013)Report Institute of Automatic Control, ETH ZürichThis paper describes autonomous racing of RC race cars based on mathematical optimization. Using a dynamical model of the vehicle, control inputs are computed by receding horizon based controllers, where the objective is to maximize progress on the track subject to the requirement of staying on the track and avoiding opponents. Two different control formulations are presented. The first controller employs a two- level structure, consisting ...Report
