A Semi-Automated System for Accurate Gaze Coding in Natural Dyadic Interactions

Daniel Gatica-Perez, Jean-Marc Odobez, Laurent Son Nguyen, Kenneth Alberto Funes Mora

In this paper we propose a system capable of accurately coding gazing events in natural dyadic interactions. Contrary to previous works, our approach exploits the actual continuous gaze direction of a participant by leveraging on remote RGB-D sensors and a ...

Quantitative thermal microscopy using thermoelectric probe in passive mode

Danick Briand

A scanning thermal microscope working in passive mode using a micronic thermocouple probe is presented as a quantitative technique. We show that actual surface temperature distributions of microsystems are measurable under conditions for which most of usua ...

Comparison of hydrologic response between a conceptual and a travel time distribution model for a snow-covered alpine catchment using Alpine3D

Andrea Rinaldo, Michael Lehning, Marc Parlange, Bettina Schaefli, Francesco Comola, Mathias Thierry Pierre Bavay, Raphaël Mutzner

Fully distributed models of alpine catchment surface processes typically use the geomorphological information provided by digital maps for describing the dynamics of rain, snow, soil and vegetation with much detail. Physically based hydrological models wou ...

Blind Phase Calibration in Sparse Recovery

Rémi Gribonval, Gilles Puy

We consider a blind calibration problem in a compressed sensing measurement system in which each sensor introduces an unknown phase shift to be determined. We show that this problem can be approached similarly to the problem of phase retrieval from quadrat ...

Design and Calibration of Ultra-high-precision Industrial Robots

Reymond Clavel, Murielle Richard, Emanuele Lubrano

In this paper we present the key phases to design and calibrate ultra-high-precision industrial robots (i.e. submicrometric precision robots). The first part of our study will cover the robot design aspects, from the choice of the kinematics with the help ...

Toxicokinetic-toxicodynamic modelling of survival of Gammarus pulex in multiple pulse exposures to propiconazole: model assumptions, calibration data requirements and predictive power

Kristin Schirmer

Toxicokinetic-toxicodynamic (TKTD) models quantify the time-course of internal concentration, which is defined by uptake, elimination and biotransformation (TK), and the processes which lead to the toxic effects (TD). TKTD models show potential in predicti ...

Automatically calibrating the viewing direction of optic-flow sensors

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod

Because of their low weight, cost and energy consumption, optic-flow sensors attract growing interest in robotics for tasks such as self-motion estimation or depth measurement. Most applications require a large number of these sensors, which involves a fai ...

Location System and Corresponding Calibration Method

Pierre-André Farine, Cyril Botteron, Phillip Tomé

The present invention relates to a location system, for locating at least one object within a predefined cell, comprising at least first and second receivers (A, B, C, D), first and second transmitters respectively, including first and second internal cloc ...

Spatially resolved skin friction velocity measurements using Irwin sensors: A calibration and accuracy analysis

Michael Lehning, Katherine Colby Leonard, Benjamin Andreas Walter

This study investigates the accuracy of spatially resolved skin friction velocity uτ measurements using a large number of Irwin sensors (Irwin, 1981). A fast and simple procedure to calibrate the sensors against a two-component hot-film anemometer is intro ...
