A storage scheme for an automated archive

Presentation given at the Al-Azhar Engineering First Conference, AEC’89, Dec. 9-12 1989, Cairo, Egypt. The paper presented at AEC'89 suggests an infinite storage scheme divided into one volume which is online and an arbitrary number of off-line volumes arranged into a linear chain which hold records which haven't been accessed recently. The online volume holds the records in sorted order (e.g. as a B-tree) and contains shortest prefixes of keys of records already pushed offline. As new records enter, older ones are retired to the first volume which is going offline next. Statistical arguments are given for the rate at which an off-line volume needs to be fetched to reload a record which had been retired before. The rate depends on the distribution of access probabilities as a function of time. Applications are medical records, production records or other data which need to be kept for a long time for legal reasons.

"Enseigner les sciences": un espace numérique d'échange et de formation concernant l'enseignement des sciences à l'école primaire

Cela fait maintenant plus de 10 ans que les premiers dispositifs de e-learning ont vu le jour, que ce soit pour la formation continue ou pour la formation initiale. Dans un premier temps, le recours aux technologies n’a consisté qu’à publier sur Internet l’ensemble des ressources ainsi que le cours, sous forme de texte, dispensé par l’enseignant. Puis, grâce à l’évolution des technologies, de nouvelles possibilités ont vu le jour : la mise en ligne de documents audios, de vidéos, et plus récemment, la mise en place d’espaces numériques de travail permettant à l’enseignant, comme à tous les participants, d’y placer des documents et des commentaires. L’apparition des wikis a permis de voir apparaître de nouvelles formes de e-learning, basés sur la collaboration. Depuis quelques mois, l’explosion des réseaux sociaux, facebook pour le plus célèbre, permet d’envisager de nouveaux dispositifs d’apprentissage interconnectant cours en présentiel et travail à distance

The ERA-Interim Archive

This document describes the ERA-Interim Archive at ECMWF. ERA-Interim is a reanalysis of the global atmosphere covering the data-rich period since 1989, and continuing in real time. As ERA-Interim continues forward in time, updates of the Archive will take place on a monthly basis.

Wheat archive links long-term population dynamics of pathogens to air pollution

We used the PCR to study the presence of two plant pathogens in archived wheat samples from a long-term experiment started in 1843. The data were used to construct a unique 160-yr time-series of the abundance of Phaeosphaeria nodorum and Mycosphaerella graminicola, two important pathogens of wheat. During the period since 1970, the relative abundance of DNA of these two pathogens in the samples has reflected the relative importance of the two wheat diseases they cause in U.K. disease surveys. Unexpectedly, changes in the ratio of the pathogens over the 160-yr period were very strongly correlated with changes in atmospheric pollution, as measured by SO2 emissions. This finding suggests that long-term, economically important, changes in pathogen populations can be influenced by anthropogenically induced environmental changes.
