Quantifying the effect of machine translation in a high-quality human translation production process

This paper studies the impact of machine translation (MT) on the translation workflow at the Directorate-General for Translation (DGT), focusing on two language pairs and two MT paradigms: English-into-French with statistical MT and English-into-Finnish with neural MT. We collected data from 20 professional translators at DGT while they carried out real translation tasks in normal working conditions. The participants enabled/disabled MT for half of the segments in each document. They filled in a survey at the end of the logging period. We measured the productivity gains (or losses) resulting from the use of MT and examined the relationship between technical effort and temporal effort. The results show that while the usage of MT leads to productivity gains on average, this is not the case for all translators. Moreover, the two technical effort indicators used in this study show weak correlations with post-editing time. The translators' perception of their speed gains was more or less in line with the actual results. Reduction of typing effort is the most frequently mentioned reason why participants preferred working with MT, but also the psychological benefits of not having to start from scratch were often mentioned

Avis de l'Ifremer sur la réalisation d'une station de traitement des eaux pluviales sur le marais du Vergeroux, commune de Rochefort sur Mer

Purpose: Almost 40 years ago, H. Cohen formulated a conjecture about the modularity of a certain infinite family of functions involving the generating function of the Hurwitz class numbers of binary quadratic forms. Methods: We use techniques from the theory of modular, mock modular, and Jacobi forms. Result: In this paper, we prove a slight improvement of Cohen's original conjecture. Conclusions: From our main result, we derive so far unknown recurrence relations for Hurwitz class numbers

Effect of the density of the culture and the depth on the seasonal variation of the biochemical composition of Crassostrea virginica in patuxent river (Chesapeake Bay)

The project of cultivation of oyster has been designed to evaluate the growth rate, the mortality, the reproductive effort, production and biochemical composition of the oyster function of the density and the depth. This plan was intended: - to build model of growth rate, - to demonstrate the action of the different parameters on growth rate (temperature, food effect...), - to evaluate the density effect to see if the available food could be a limiting factor, - to estimate the effect of the depth joined to the impact of the high turbidity near the bot tom, - to detect the mortality related to the prevalence of diseases. The project began in July 1989 by dredging 20 000 small oysters at the mouth of the Patuxent River near Cove Point. Three experimental stations were selected in the Patuxent River to set up the structures, Benedict Bridge in the upper and the brackish water zone, Green Holly Pond at the mouth of the river and Chesapeake Biological Laboratory's Pier
