Improved overlap speech diarization of meeting recordings using long-term conversational features

Overlapping speech is a source of significant errors in speaker diarization of spontaneous meeting recordings. Recent works on speaker diarization have attempted to solve the problem of overlap detection using classifiers trained on acoustic and spatial fe ...

Decentralized list scheduling

Nicolas Gabriel Gast, Denis Trystram

Classical list scheduling is a very popular and efficient technique for scheduling jobs for parallel and distributed platforms. It is inherently centralized. However, with the increasing number of processors, the cost for managing a single centralized list ...

Randomized Extended Kaczmarz For Solving Least Squares

Nikolaos Freris

We present a randomized iterative algorithm that exponentially converges in the mean square to the minimum l(2)-norm least squares solution of a given linear system of equations. The expected number of arithmetic operations required to obtain an estimate o ...

Uptake and release kinetics of 22 polar organic chemicals in the Chemcatcher passive sampler

Juliane Hollender

The Chemcatcher passive sampler, which uses Empore (TM) disks as sampling phase, is frequently used to monitor polar organic chemicals in river water and effluents. Uptake kinetics need to be quantified to calculate time-weighted average concentrations fro ...

Hydrophobic Meshes for Oil Spill Recovery Devices

Francesco Stellacci

Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...

Similarity Learning Over Large Collaborative Networks

Majid Yazdani

In this thesis, we propose novel solutions to similarity learning problems on collaborative networks. Similarity learning is essential for modeling and predicting the evolution of collaborative networks. In addition, similarity learning is used to perform ...

Spatially resolved photocurrents in graphene nanoribbon devices

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Kannan Balasubramanian, Adarsh Singh Sagar, Thomas Dufaux

We present here a scanning photocurrent microscopy study of individual graphene nanoribbons, revealing pronounced photocurrent responses close to the nanoribbon/metal contacts. The magnitude of the corresponding photocurrent signal was found to be directly ...

Piezoelectric AlScN thin films: A semiconductor compatible solution for mechanical energy harvesting and sensors

Paul Muralt, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Andrea Mazzalai, Mahmoud Hadad, Nachiappan Chidambaram

The transverse piezoelectric coefficient e31,f of Al1-xScxN thin films was investigated as a function of composition. It increased nearly 50% from x = 0 to x = 0.17. As the increase of the dielectric constant was only moderate, these films are very suitabl ...

Eu3+-doped (Y0.5La0.5)(2)O-3: new nanophosphor with the bixbyite cubic structure

Barbora Bártová

New red sesquioxide phosphor, Eu(3+)doped (Y0.5La0.5)(2)O-3, was synthesized in the form of nanocrystalline powder with excellent structural ordering in cubic bixbyite-type, and with nanoparticle sizes ranging between 10 and 20 nm. Photoluminescence measur ...

Joint Reconstruction of Multi-view Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

The distributed representation of correlated multi-view images is an important problem that arise in vision sensor networks. This paper concentrates on the joint reconstruction problem where the distributively compressed correlated images are jointly decod ...
