A touch of Henry Moore and the Nits

Reclining figure, Henry Moore, Lincoln Center New York could as well have been Dutch. In 1609, English explorer Henry Hudson (according to wikipedia):  re-discovered the region, sailing for his employer the Dutch East India Company . He proceeded to sail up what he named the North River , also called the Mauritis River , and now known as the Hudson River , to the site of the present-day New York State capital of Albany in the belief that it might represent an oceanic tributary . When the river narrowed and was no longer saline , he realized it wasn't a sea passage and sailed back downriver. He made a ten-day exploration of the area and claimed the region for his employer. In 1614 the area between Cape Cod and Delaware Bay would be claimed by the Netherlands and called Nieuw-Nederland ( New Netherland ). The capital of Nieuw-Nederland was located in the southern tip of Manhattan. A last proof is the New York City flag, derived from the Prince's flag, th

Gas chromatography and 2D-gas chromatography for petroleum industry: The race for selectivity

Almost a follow-up to Signal Processing for Chemical Sensing: ICASSP 2013 Special session : the book Gas chromatography and 2D-gas chromatography for petroleum industry: The race for selectivity , edited by Fabrice Bertoncini, Marion Courtiade-Tholance, Didier Thiébaut (2013, éditions Technip) is out. Our contribution lies in Chapter 3: "Data processing applied to GCxGC. Applications to the petroleum industry.". Detailed knowledge of petroleum products at molecular scale has always been essential to understand the mechanisms leading to their formation, to design thermodynamic and kinetic models employed in the refining processes and to predict their physical properties. In view of the complexity of petroleum products, very significant research efforts have been made over the past 15 years for improving relevant analytical techniques, especially in the field of Gas Chromatography in order to improve its separation power. The advent of comprehensive Two-dimensional Gas

Signal Processing for Chemical Sensing: ICASSP 2013 Special session

Image
ICASSP 2013 (International conference on acoustic, speech and signal processing) takes place at the end of May 2013 in Vancouver, Canada. The technical program is online . Among the numerous tracks and sessions, there were a special session on Signal Processing for Chemical Sensing (Friday, May 31, 08:00 - 10:00). The chairpersons were: Leonardo T. Duarte , Laurent Duval , Christian Jutten . Here are posted the slides ( all slides in a .zip file ) presented at the conference and paper abstracts. Typical chemical signals: 1D gas chromatogram Summary of the Special Session: This special session aims at showing some relevant problems in chemical engineering that can be addressed with classical or advanced methods of signal and image processing. It will be introduced by a tutorial paper, presented by the organizers, who will offer a large overview of issues which have been addressed in this application domain, like chemical analysis leading to PARAFAC/tensor methods,
