Who is the expert? analyzing gaze data to predict expertise level in collaborative applications

Pierre Dillenbourg, Mirweis Sangin, Marc-Antoine Nüssli, Yuan Liu, Yan Liu

In this paper, we analyze complex gaze tracking data in a collaborative task and apply machine learning models to automatically predict skill-level differences between participants. Specifically, we present findings that address the two primary challenges ...

Graph signature for self-reconfiguration planning

Auke Ijspeert, Pierre Dillenbourg, Aude Billard, Masoud Asadpour

This project incorporates modular robots as building blocks for furniture that moves and self-reconfigures. The reconfiguration is done using dynamic connection / disconnection of modules and rotations of the degrees of freedom. This paper introduces a new ...

Cooperative and redundant roles of VEGFR-2 and VEGFR-3 signaling in adult lymphangiogenesis

Melody Swartz, Joseph Rutkowski, Miriella Carmela Pasquier

Activation of vascular endothelial growth factor ( VEGF) receptor-3 (VEGFR-3) by VEGF-C initiates lymphangiogenesis by promoting lymphatic proliferation and migration. However, it is unclear whether VEGFR-3 signaling is required beyond these initial stages ...

Thermodynamic Parameters Governing the Self-Assembly of Head–Head–Head Lanthanide Bimetallic Helicates

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

Abstract: The heterobitopic ligands LABX (X=1,2, 3,4 or 5),diff ering only by a Cl or NEt2 substituent,have been designed to complex with a pair of lanthanide ions to form triple-stranded bimetallic helicates of overall composition [Ln2ACHTUNGTRENUNG(LABX) ...

Small-signal characteristics of AlInN/GaN HEMTs

Nicolas Grandjean, Jean-François Carlin, Marcel Py, Marcus Gonschorek

DC and RF measurements of an emerging AIInN/GaN high electron mobility transistor (HEMT) technology for power performances are reported. High electron transport properties in this structure attributed to the material quality are demonstrated. Indeed, in sp ...

The effect of bisphosphonates and titanium particles on osteoblasts: an in vitro study

Dominique Pioletti, Bastian Peter

In an attempt to increase the life of cementless prostheses, an hydroxyapatite-coated implant which releases a bisphosphonate has been suggested as a drug-delivery system. Our in vitro study was designed to determine the maximum dose to which osteoblasts c ...

Proactive Steering Toward Oriented Targets

Ronan Boulic

In this paper we introduce a real-time steering controller ensuring the reach of a (possible mobile) target position and orientation, without requiring to build/update the full trajectory to that target. We name it the funnelling control. The final orienta ...

Electrochemically Induced Oscillations of C2H4 Oxidation Over Thin Sputtered Rh Catalyst Films

Christos Comninellis, György Foti

The electrochem. promoted induction of self-sustained catalytic rate and potential oscillations during C2H4 oxidn. was studied over sputtered Rh thin (40 nm catalyst films interfaced with ZrO2 (8 mol% Y2O3)). The reaction rate oscillates simultaneously wit ...

The development of material-adapted structural form

Sean Dooley

New structural materials can potentially change the technics and economics of the building and construction industry in a profound way. It is important to identify applications and develop forms that exploit a material's unique properties. The developer of ...

CDMA location using multiple antennas and interference cancellation

Ali H. Sayed

Location finding for CDMA subscribers using an antenna array at the base station and deploying multiple base stations is studied in this paper. Two methods are considered for radio location: measured time-of-arrival (TOA) and angle-of-arrival (AOA), and al ...
