Encapsulation of Conjugated Oligomers in Single-Walled Carbon Nanotubes: Towards Nanohybrids for Photonic Devices

Visible-light emitting single-walled carbon nanotubes (SWNTs)/organic hybrids have been successfully synthesized and promise to be a photon source to be used in future optoelectronic devices. The nanohybrids are "peapods" having sexithiophene molecules ins ...

Estimation of travel time on urban networks with midlink sources and sinks

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

This paper presents a methodology for estimation of average travel time on signalized urban networks by integrating cumulative plots and probe data. This integration aims to reduce the relative deviations in the cumulative plots due to midlink sources and ...

Loss Tomography in General Topologies with Network Coding

Christina Fragouli

Network tomography infers internal network characteristics by sending and collecting probe packets from the network edge. Traditional tomographic techniques for general topologies typically use a mesh of multicast trees and/or unicast paths to cover the en ...

A Galileo E1b,c RF front-end for Search-and-Rescue applications

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti

The current Search-and-Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the 121.5MHz/(up to ...

Bone diagnostic instrument

Georg Fantner

The bone diagnostic instrument is designed to measure materials properties of bone even if it is covered with soft tissue such as periosteum, connective tissue and skin. It uses (1) a probe assembly, consisting of a reference probe that penetrates soft tis ...

Fluctuation measurements using a five-pin triple probe in the Joint European Torus boundary plasma

Richard Pitts

A multi-probe system has been developed to investigate the importance of electron temperature fluctuations turbulent transport in the Joint European Torus boundary plasma. The compact five-pin triple probe has been designed to reduce the phase delay of flu ...

Experimental investigation of a vibrating axial turbine cascade in presence of upstream generated aerodynamic gusts

Fabrice Rottmeier

An experimental investigation has been conducted in the non-rotating annular test facility of the "Laboratoire de Thermique Appliquée et de Turbomachines" (LTT), "École Polytechnique Fédérale de Lausanne" (EPFL). During this investigation, the unsteady aer ...

On-chip generation and detection of electrochemiluminescence

Nico de Rooij

A miniaturized and fully integrated probe for analytical assays based on electrochemiluminescence (ECL) is proposed. It combines both, the electrode transducer and the photodetector in a single 5x6 mm2 silicon chip. The device accommodates two identical ce ...
