Airborne Hyperspectral Imaging of Lakes

In a time of rising concern about climate change and pollution, the water quality of large lakes acts as an indicator of the health of the environment. To study the water quality at a large scale - up to several hundreds of kilometres - hyperspectral remot ...

Time-resolved X-ray and Optical Studies of Metalloproteins and Iridium Complexes

Mahsa Silatani

A wide variety of physicochemical processes at a molecular level, in particular charge or energy transfer, electronic and vibrational relaxation, are at the origin of biological functionality of proteins and organometallic compounds. The work reported in t ...

LFI systematic uncertainties

Julien Lesgourgues, Fabio Finelli

We present the current estimate of instrumental and systematic effect uncertainties for the Planck-Low Frequency Instrument relevant to the first release of the Planck cosmological results. We give an overview of the main effects and of the tools and metho ...

Estimation of power spectra of acoustic-doppler velocimetry data contaminated with intermittent spikes

Fernando Porté Agel

Spectral analysis of velocity signals recorded by acoustic-Doppler velocimetry (ADV) and contaminated with intermittent spikes remains a challenging task. In this paper, we propose a new method for reconstructing contaminated time series, which integrates ...

Propriétés optiques de petits agrégats de métaux nobles en matrice de néon

Sylvain Lecoultre

The optical properties of small noble metal clusters have been studied by absorption and fluorescence for sizes between 1 and 10 atoms. The experimental technique consists in depositing size-selected clusters in a neon matrix and analyzing with a spectrome ...

Medium-range structure of vitreous SiO2 obtained through first-principles investigation of vibrational spectra

Alfredo Pasquarello, Luigi Giacomazzi, Paolo Umari

Using a density-functional framework, we investigate the vibrational spectra of vitreous SiO2 to determine to what extent these spectra provide information about the medium-range structure of the oxide network. We carry out a comparative study involving th ...

H-1 NMR spectroscopy of rat brain in vivo at 14.1 Tesla: Improvements in quantification of the neurochemical profile

Rolf Gruetter, Lijing Xin, Cristina Ramona Cudalbu

Ultra-short echo-time proton single voxel spectra of rat brain were obtained on a 14.1 T 26 cm horizontal bore system. At this field, the fitted linewidth in the brain tissue of adult rats was about 11 Hz. New, separated resonances ascribed to phosphocholi ...

Turbulent kinetic energy budgets in a model canopy: comparisons between LES and wind-tunnel experiments

Marc Parlange, Charles Vivant Ignacio Meneveau

A comparative study of turbulence in a wind-tunnel model canopy is performed, using Large eddy simulation (LES) and experimental data from PIV and hot-wire anemom¬etry measurements. The model canopy is composed of thin cylindrical stalks. In the LES, these ...

Electrostatic instabilities and turbulence in a toroidal magnetized plasma

Francesca Maria Poli

This Thesis aims at characterizing the linear properties of electrostatic drift instabilities arising in a toroidal plasma and the mechanisms leading to their development into turbulence. The experiments are performed on the TORoidal Plasma EXperiment (TOR ...

Power Spectra of Multipath Faded Pulse Trains

Andrea Ridolfi

We address the problem of modeling received pulse trains in a multipath fading channel and of computing their exact spectrum. We propose a model based on point processes. Such model is very general, simple and tractable and it allows to account for various ...
