Delayed voltammetric with respect to amperometric electrochemical detection of concentration changes in microchannels

Martinus Gijs, Raphaël Etienne Jean Trouillon

The time response of an electrode incorporated into a fluidic channel to variations in analyte concentration of the outer-sphere redox probe ferrocenemethanol was investigated both for amperometry (AMP) and cyclic voltammetry (CV). The experimental data sh ...

Distributed Measurement of Signal Power Evolution in a Phase Sensitive Parametric Amplifier

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Fatemeh Alishahi, Andrey Denisov

A method to measure the signal power evolution along phase-sensitive parametric amplifiers is proposed using Brillouin optical time-domain analysis. Different evolutions along the fiber are reported by varying input wave phases, including amplification and ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XII. Time delays of the doubly lensed quasars SDSS J1206+4332 and HS 2209+1914

Frédéric Courbin, Georges Meylan, Malte Tewes

Aims. Within the framework of the COSMOGRAIL collaboration we present 7- and 8.5-year-long light curves and time-delay estimates for two gravitationally lensed quasars: SDSS J1206+4332 and HS 2209+1914. Methods. We monitored these doubly lensed quasars in ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIV. Time delay of the doubly lensed quasar SDSS J1001+5027

Frédéric Courbin, Georges Meylan, Malte Tewes

This paper presents optical R-band light curves and the time delay of the doubly imaged gravitationally lensed quasar SDSS J1001+5027 at a redshift of 1.838. We have observed this target for more than six years, between March 2005 and July 2011, using the ...

Application of Brillouin-Based Continuously Tunable Optical Delay Line to Contention Resolution Between Asynchronous Optical Packets

Luc Thévenaz, Sang Hoon Chin, Andrea Trita

A novel approach for resolution of contentions between asynchronous optical packets, exploiting a self-synchronizing mechanism by means of dynamic all-optical tunable delay line based on stimulated Brillouin scattering in fibers, is reported. Time delay be ...

Non-linear magnetic perturbations during edge-localized modes in TCV dominated by low n mode components

Olivier Sauter, Holger Reimerdes, Hartmut Zohm

Edge-localized modes (ELMs) are instabilities in the edge of tokamak plasmas in the high confinement regime (H-mode). Despite beneficial aspects of ELMs, in a future device the size of the energy loss per ELM must be controlled, in order to avoid intolerab ...

Solid-state proton NMR of paramagnetic metal complexes: DANTE spin echoes for selective excitation in inhomogeneously broadened lines

Geoffrey Bodenhausen, Gerald Bauer, Diego Carnevale, Angel Joaquin Perez Linde

The paramagnetic complex bis(oxazolinylphenyl)amine-Fe(III)Cl-2 is investigated by means of solid-state proton NMR at 18.8 T (800 MHz) using magic-angle spinning at 65 kHz. Spin echoes that are excited and refocused by combs of rotor-synchronized pulses in ...

Real-time Optimized Rendezvous on Nonholonomic Resource-Constrained Robots

Alcherio Martinoli, Sven Adrian Gowal

In this work, we consider a group of differential-wheeled robots endowed with noisy relative positioning capabilities. We develop a decentralized approach based on a receding horizon controller to generate, in real-time, trajectories that guarantee the con ...

Robust Smith Predictor Design for Time-Delay Systems with H infinity Performance

Alireza Karimi, Vinicius De Oliveira

A new method for robust fixed-order H-infinity controller design for uncertain time-delay systems is presented. It is shown that the H-infinity robust performance condition can be represented by a set of convex constraints with respect to the parameters of ...
