Virgile, prophète du monothéisme dans l’Antiquité tardive ?
No full textInternational audienceThe Christians of Late Antiquity, taken as a whole, do not consider Virgil as a prophet of their beliefs, unlike the Sibyl, whose “true” oracles are considered to have inspired the poet. For most of the non-Christians of the declining Empire, Virgil, whose prestige and authority are unequaled, is not the sacred author of a “pagan Bible”, as some scholars have written. Examples of such interpretations are isolated (the Speech to the Assembly of the Saints, the Cento of Proba, the Saturnalia of Macrobius) and bear witness to monotheistic appropriations, Christian and non-Christian, which remain very original, and crystallize the different stages of the Christianization of the Roman empire.Les chrétiens de l’Antiquité tardive, pris dans leur ensemble, ne considèrent pas Virgile comme un prophète de leurs croyances, contrairement à la Sibylle, dont les oracles « véridiques » auraient inspiré le poète. Pour la plupart des non-chrétiens de l’empire tardif, Virgile, dont le prestige et l’autorité sont inégalables, n’est pas non plus pour autant l’auteur sacré d’une « Bible païenne », comme l’ont écrit certains historiens de la période. Les exemples de telles interprétations sont isolés (le Discours à l’Assemblée des Saints, le Centon de Proba, les Saturnales de Macrobe) et témoignent d’appropriations monothéistes, chrétiennes et non chrétiennes, très originales, qui cristallisent les différentes étapes de la christianisation de l’empire
Fables complètes
No full textThis paperback is apparently a re-issue of a hardbound book of the same title by the same publisher in 2001. Virgile, Léon Crabbé, died at the age of about eighty in 1970, having written, apparently, hundreds of columns – especially in the column "Pourquoi Pas?" -- and having made many recordings. Many see him. as does his friend Jean Francis, as the the ideal manifestation of the spirit of Brussels. Here we have seventeen of his redoings of La Fontaine's fables and then about twenty-four of his "fables personnelles." These are followed by "the fables of Suske le Brugeois, Noel Barcy." This is yet another pseudonym for the author. These again take up La Fontaine as models, but they seem to add some mockery of Brugians' confusion with French articles, masculine and feminine. They also play more drastically with the endings of La Fontaine's fables. A last section offers the originals of La Fontaine's fables developed in this book. This book was sitting at my door as I returned to my room after my first breakfast at St. Michel Jesuit high school in Brussels. The author had been mentioned at breakfast. I value the book as a wonderful gift! Footnotes and a Brussels vocabulary help! The cover presents a crow perched on a tall building looking down with cheese in his beak at a waiting fox. Jean Francis: "Si vous voulez vous ouvrir le coeur de Bruxelles, je ne vois guère d'autre clé."Language note: FrenchVirgile du Pourquoi Pas
L’Eneide travestita di Giovanni Battista Lalli e il Virgile travesti di Paul Scarron: un confronto
No full textAmong the numerous examples of literary travesty written during the 17th century, Giovanni Battista Lalli’s Eneide travestita and Paul Scarron’s Virgile travesti represent a curious coincidence. The relationship between the two texts, published 15 years apart from each other, has been studied by different critics, who have highlighted either the analogies, that may suggest a direct influence of one author (Lalli) over the other (Scarron), or the differences, which on the contrary could imply the complete independence of the latter from the former. A close analysis of both works, however, shows that the truth might be more complex
Optimization models and methods for storage yard operations in maritime container terminals
No full textThesis: Ph. D., Massachusetts Institute of Technology, Sloan School of Management, Operations Research Center, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 175-182).Container terminals, where containers are transferred between different modes of transportation both on the seaside and landside, are crucial links in intercontinental supply chains. The rapid growth of container shipping and the increasing competitive pressure to lower rates result in demand for higher productivity. In this thesis, we design new models and methods for the combinatorial optimization problems representing storage yard operations in maritime container terminals. The goal is to increase the efficiency of yard cranes by decreasing unproductive container moves (also called relocations). We consider three problems with applicability to real-time operations. First, we study the container relocation problem that involves finding a sequence of container moves that minimizes the number of relocations needed to retrieve all containers, while respecting a given order of retrieval. We propose a new binary integer program model, perform an asymptotic average case analysis, and show that our methods can apply to other storage systems where stacking occurs. Second, we relax the assumption that the full retrieval order of containers is known in advance and study the stochastic container relocation problem. We introduce a new model, compare it with an existing one, and develop two new algorithms for both models based on decision trees and new heuristics. We show that techniques in this chapter apply more generally to finite horizon stochastic optimization problems with bounded cost functions. Third, we consider the integrated container relocation problem and yard crane scheduling problem to find an optimal sequence of scheduled crane moves that perform the required container movements. Taking into account practical constraints, we present a new model, propose a binary integer program using a network flow-type formulation, and design an efficient heuristic procedure for real-time operations based on properties of our mathematical formulation. We relate this problem to pick-up and delivery problems with a single vehicle and capacities at every node. In all three chapters, the efficiency of all our algorithms are shown through extensive computational experiments on available problem instances from the literature and/or on real data.by Virgile Galle.Ph.

A Component-Based Formal Language Workbench
No full textThe CBS framework supports component-based specification of programming languages. It aims to significantly reduce the effort of formal language specification, and thereby encourage language developers to exploit formal semantics more widely. CBS provides an extensive library of reusable language specification components, facilitating co-evolution of languages and their specifications. After introducing CBS and its formal definition, this short paper reports work in progress on generating an IDE for CBS from the definition. It also considers the possibility of supporting component-based language specification in other formal language workbenches.Programming Language
Physiological differences among cryptic species of the Mediterranean crustose coralline alga Lithophyllum stictiforme (Corallinales, Rhodophyta)
No full textInternational audienceThe crustose coralline alga Lithophyllum stictiforme is an important reef builder, forming coralligenous concretions in the Mediterranean Sea. This algal species complex is composed of eight cryptic species (or clades). The objective of our study was to compare light-dependent physiological processes within and between the two most abundant cryptic species (C1 and C4) of L. stictiforme from the Bay of Marseille (France). Physiological rates of respiration, photosynthesis and calcification were measured using incubation chambers under various irradiance levels and in the dark during the summer period. We compared the physiology of the C1 and C4 cryptic species of L. stictiforme among three algal groups: C1 (the most common in the Marseille area) from 28 m depth, C4 from the same site and depth, and C1 from a deeper site at 45 m depth. We found both interspecific (between C1 and C4) and intraspecific (within C1) physiological differences. Photosynthetic parameters showed acclimation to light (or depth) with higher values of initial slope of photosynthetic light response curve (α) and lower values of saturating irradiance (Ek) and compensating irradiance (Ec) for C1 from 45 m than for C1 and C4 from 28 m depth. At the shallower depth, significant physiological differences were observed between C1 and C4 with a higher value of maximum rate of gross photosynthesis (Pg max) in C4, suggesting better ability to grow under high irradiance. Light and dark calcification rates differed only between C4 from 28 m and C1 from 45 m depth, being intermediate in C1 from 28 m depth. On a 24 h basis, diel net calcification rates were significantly higher in specimens from the shallower waters than from the deeper waters. Physiological differences suggest physiological plasticity within the regionally dominant cryptic species C1 and species-specific physiological traits between the cryptic species C1 and C4

Scarron et Scarron II : une seule rhétorique de la parodie?
No full textThe author undertakes a comparative study of Le Virgile Travesti, a parody of Eneid written by the 17th century French burlesque poet Scarron, and of Les Lusiades Travestis, a parody of Camoes' epic poem written in Portugal in the 19th century by a French writer using the pseudonym Scarron II: an attempt is also made to discover the real identity of the latter
Sporulation and physiological profiles of bacterial communities of three Mediterranean soils affected by drying-rewetting or freezing-thawing cycles
No full textInternational audienceIn the global change context, the basal respiration (BR), the estimated number of bacterial spores (SP) and the community level physiological profiles (CLPPs) were investigated in three different Mediterranean soils following different hydric and thermic stress scenarios. The treatments consisted in an increasing number (1, 2, 4, and 7) of drying-rewetting (DRWc) or freezing-thawing cycles (FR) at 20, 40 or -20 degrees C. The results highlighted that the different soils responded differently to the same treatment and that the three variables considered were weakly related one to each another. In almost all soils and modalities, the BR increased significantly during the first cycles before decreasing during the last. With regards to SP, it appeared that, for a given soil, the capacity of microbial communities to sporulate and/or germinate can be considerably more influenced by the temperature rather than by the hydric stress. Finally, the CLPPs literally collapsed with the treatment at 40 degrees C, irrespective of the soil considered. This suggested a progressive replacement of the catabolically diversified original bacterial communities by another showing lower functional diversities
