Initial Investigations into the Use of Three Heuristic Algorithms to Determine Optimal Intervention Programs for Multiple Railway Objects
No full textCAPRI versus AGLINK-COSIMO: Two partial equilibrium models - Two baseline approaches
Full text linkThe agricultural modelling world has generated several models aiming at the analysis of the response of the sector to certain changes in exogenous mainly policy variables. Among those, the CAPRI modelling system developed by a consortium centred on the University of Bonn and the AGLINK-COSIMO model, a joint product of the OECD and the FAO, are well known and accepted as comprehensive tools. This analysis focuses on a qualitative comparison of both models and particularly on the process of setting up the baseline. The baseline is a medium-term projection of agricultural markets reflecting current policies and those already decided upon. This projection in turn serves as the base for comparisons when analyzing scenarios. It is shown that CAPRI uses generic and automatic procedures whenever possible for conducting the database and the baseline, while AGLINK-COSIMO puts more emphasis on expert knowledge in this process. Both approaches are shown to have certain advantages while the conclusion that a combination of them would potentially improve both models will be drawn from this analysis.CAPRI, AGLINK-COSIMO, Baseline process, Agricultural and Food Policy,
Determination of Risk-Reducing Intervention Programs for Railway Lines and the Significance of Simplifications
No full textBecause failures on railway lines have nonzero probabilities of occurrence and can result in significant costs if they occur, railway infrastructure managers are interested in determining intervention programs that best reduce this risk, taking into consideration their budget constraints. In this paper, a base model is proposed to determine optimal risk-reducing intervention programs for railway lines based on the states of its objects and budget availability. The base model is an integer nonlinear model with an objective function that maximizes net benefit without exceeding budget constraints. The net benefit is the difference between the amount of risk reduction and the costs of executing interventions in terms of both direct costs (i.e.,materials and labor forces) and indirect costs (i.e.,the travel time costs). Three variations of the base model, i.e.,the object model, the block model, and the line model, are used to investigate the trade-offs between increasingly simplified models and decreasing ability to determine the optimal intervention program due to decreasing ability to accurately estimate costs and benefits. In the object model, objects are considered in isolation, i.e.,while each object fails and is restored all other objects in the line are fully functional. In the block model, blocks are observed in isolation, i.e.,while each block fails and is restored all objects in the line are fully functional, whereas the multiple objects within a block may fail and be restored simultaneously. In the line model, all objects in the line may fail and be restored simultaneously. Fault tree analysis is used in the block and line models to estimate the costs of the combined failures of multiple objects. The three models are demonstrated by using them to determine the optimal intervention program for a fictive railway line between two stations that consisted of eight track sections, a bridge, two switches, and two signals. The intervention programs determined using the three models in terms of the interventions included and the net benefit obtained are compared. It is shown that all three variations produce useful results but that there are significant differences in the estimation of the net benefits using the three different models, and that these differences lead to different interventions being included in the determined intervention programs, and consequently in the net benefit that will be achieved through their implementation. It was also shown that each improvement in the estimation of accuracy comes with an increase in modeling complexity. (c) 2017 American Society of Civil Engineers

Ruskin traduzido: Sesame and Lilies por Proust e Catalán
Full text linkTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2009.Este trabalho parte da análise das traduções da obra Sesame and Lilies, de John Ruskin, para o francês e para o castelhano para fazer um exame de questões ligadas ao gênero ensaístico, à tradução de ensaios e à autoria. Para isso, analisarei a tradução de Marcel Proust para o francês e seu paratexto e a tradução para o castelhano feita por Miguel Catalán e o respectivo paratexto.This study analises the translations of Sesame and Lilies, by John Ruskin, into French and Spanish in order to examine issues related to the essay as a literary genre, to the translation of essays and to authorship. This exam will be carried out by analising the translation into French by Marcel Proust and its paratext and the translation into Spanish by Miguel Catalán, accompanied by its paratext
Jean-Marcel Jeanneney à l'OFCE - Fondations et contributions (1981-1989).
Full text linkJean-Marcel Jeanneney était un économiste rare, à la fois théoricien, empiriste et praticien. C’est son aventure à la tête de l’OFCE que ce livre raconte, ou plutôt qu’il laisse l’auteur lui-même conter au travers d’articles écrits depuis le premier jour de son premier mandat de Président de notre institution. Ce recueil s’ouvre sur une introduction qui rappelle l'attachement du fondateur de l’OFCE au « libéralisme intellectuel», cette indépendance vis-à-vis des idées reçues qu’il jugeait indispensable à la conduite de politiques publiques raisonnables. Il est ensuite structuré en trois parties dont les titres font écho à une oe uvre marquante de Jean-Marcel Jeanneney : Vouloir le débat public en économie, Une mémoire au service de la prospective et Écoute le monde qui vient : intégration globale et unification européenne. Ce volume est un hommage à la mémoire de Jean-Marcel Jeanneney mais plus encore à sa présence. Les textes rassemblés ici par Jean-Paul Fitoussi et Éloi Laurent nous rappellent l’actualité des enseignements les plus précieux de Jean-Marcel Jeanneney : honnêteté, courage et espérance.
