Model-based fit procedure for power-law-like spectra

$1/f^\alpha$ noises are ubiquitous and affect many measurements. These noises are both a nuisance and a peculiarity of several physical systems; in dielectrics, glasses and networked liquids it is very common to study this noise to gather useful information. Sometimes it happens that the noise has a power-law shape only in a certain frequency range, and contains other important features, that are however difficult to study because simple fits often fail. Here I propose a model-based fit procedure that performs well on spectra obtained in a molecular dynamics simulation.Comment: 12 postscript figures, submitted to J. Comp. Phy

Novità formali nelle sonate per violino Op. II di Vivaldi

Novità formali delle sonate per violino e continuo op. II (1709) e op. V (1716) di Antonio Vivaldi e delle raccolte manoscritte di Dresda (c. 1716) e di Manchester (c. 1726) con riferimento alla produzione coeva pubblicata tra il 1700 (Corelli) e 1750 (Tessarini, Sammartini

Hydrogen from wind curtailment for a cleaner European road transport system

Wind power is currently curtailed in order to stabilise power systems and due to economic considerations. Using curtailed wind energy to produce hydrogen could fuel hundreds of thousands of new cars. Producing hydrogen from wind curtailment is however still more expensive than buying it at market price.JRC.C.7-Knowledge for the Energy Unio

L’histoire de l’art est une histoire de prophéties

La première illustration de cet article est un montage composé de la moitié de l’une des lunettes de la Chapelle Sixtine (1508-1512) et d’une photo d’une scène de En attendant Godot de Samuel Beckett, une production canadienne de 2003 (fig. 1).

Histoire et théorie de l’art et des images à l’époque moderne

Giovanni Careri, directeur d’études Détruire la peinture. Histoire et temporalités chez Caravage La question de l’adresse au spectateur et celle de la temporalité interne au tableau ont été au centre de notre séminaire. Elles ont été posées à travers la réflexion, en partie convergente, de Louis Marin et de Michael Fried. Alors que Marin construit un dialogue serré entre le travail du Caravage et celui de Poussin, en faisant subtilement intervenir la notion freudienne de « castration », Fried..
