Interactive Generation of Calligraphic Trajectories from Gaussian Mixtures
The chapter presents an approach for the interactive definition of curves and motion paths based on Gaussian mixture model (GMM) and optimal control. The input of our method is a mixture of multivariate Gaussians defined by the user, whose centers define a ...
Springer2019Change of beam distribution due to decoherence in the presence of transverse feedback
Xavier Buffat, Sondre Vik Furuseth
The effect of Landau damping is often calculated based on a Gaussian beam distribution in all degrees of freedom. The stability of the beam is however strongly dependent on the details of the distribution. The present study focuses on the change of bunch d ...
IOP PUBLISHING LTD2019Influence of curved delamination front on R-curve of DCB specimen
Thomas Keller, Anastasios Vassilopoulos, Zhengwen Jiang
This work investigated the evolution of the non-uniform distribution of Mode-I strain energy release rate (SERR) along a straight pre-crack front of double cantilever beams (DCB), caused by the anticlastic deformation and the longitudinal free-edge effects ...
ELSEVIER SCI LTD2019Statistical Aspects of Wasserstein Distances
Wasserstein distances are metrics on probability distributions inspired by the problem of optimal mass transportation. Roughly speaking, they measure the minimal effort required to reconfigure the probability mass of one distribution in order to recover th ...
ANNUAL REVIEWS2019An Alternate Statistical Lens to Look at Collaboration Data: Extreme Value Theory
Kshitij Sharma, Jennifer Kaitlyn Olsen
To provide beneficial feedback to students during their collaboration, it is important to identify behaviors that are indicative of good collaboration. However, in a collaborative learning session, students engage in a range of behaviors and it can be diff ...
2019Procrustes Metrics and Optimal Transport for Covariance Operators
Covariance operators play a fundamental role in functional data analysis, providing the canonical means to analyse functional variation via the celebrated Karhunen-Loève expansion. These operators may themselves be subject to variation, for instance in con ...
EPFL2019Generating Calligraphic Trajectories with Model Predictive Control
We describe a methodology for the interactive definition of curves and motion paths using a stochastic formulation of optimal control. We demonstrate how the same optimization framework can be used in different ways to generate curves and traces that are g ...

Mark Pauly, Yuliy Gennadievich Schwartzburg
Method of designing a refractive surface, comprising providing a refractive object having a refractive surface with an initial geometry, determining a refraction of incident illumination through the refractive surface with the initial geometry to create a ...
2017Differential Flatness of Quadrotor Dynamics Subject to Rotor Drag for Accurate Tracking of High-Speed Trajectories
Abstract: In this letter, we prove that the dynamical model of a quadrotor subject to linear rotor drag effects is differentially flat in its position and heading. We use this property to compute feedforward control terms directly from a reference trajecto ...
2017Ultrasonic driving method
A method for driving a first component (11) into a second component (12) by superimposing a mechanical wave of ultrasonic frequency (18) onto the movement (17) of at least one of the components (11, 12). The method comprises a step of adjusting the paramet ...
