Le collocazioni in traduzione e interpretazione tra italiano e francese: Uno studio su eptic_01_2011

This dissertation aims at investigating differences in phraseological patterns in translated and interpreted language, on the basis of the intermodal corpus EPTIC_01_2011 and focusing on Italian and French. First of all, an overview is offered of the main studies and theories about corpus linguistics and collocations: the notion of corpus is defined and a typology (focusing on intermodal corpora) is presented, before moving on to the linguistic phenomenon of collocation and its investigation through corpus linguistics methods. Second, the general structure of EPTIC_01_2011 is presented, including the ways in which its texts have been assembled, edited through ad hoc conventions and enriched with metadata. The methodology proposed by Durrant and Schmitt (2009), slightly edited to fit the present study, has been used to extract and compare noun+adjective/adjective+noun bigrams from a quantitative point of view. A subset of these data have then been extracted and analysed manually. The results of the study are presented through graphs and examples, with an in-depth discussion of the bigrams considered. Lastly, the data collected are analysed and categorised in terms of shifts occurring in translation and in interpreting, potential causes are discussed and ideas for further research and for the development of the EPTIC corpus are sketched.

Le collocazioni in traduzione e interpretazione tra italiano e inglese: Uno studio su eptic_01_2011

The aim of this dissertation is to investigate the differences in the phraseological patterns used by Italian and English translators and interpreters through the intermodal corpus EPTIC_01_2011. First, the most important studies and theories about corpus linguistics and collocations are introduced. After defining the notion of “corpus”, the different types of corpora are categorised, giving particular attention to the intermodal one. Then the dissertation focuses on a description of collocations, as defined by the main linguistics scholars, and it describes some attempts to apply corpus linguistics to the study of collocations. Secondly, EPTIC_01_2011 is presented, with a description of its structure and of the text editing process carried out applying specific editing conventions and adding a set of metadata before each text. The analysis of collocation candidate bigrams (adjective+noun/noun+adjective) from a quantitative point of view, was conducted applying a methodology adapted from Durrant and Schmitt (2009). Qualitative analysis was also performed on a subsection of the data. The results of the study are presented through examples and graphs, giving particular attention to the interpretation of the data analysed from a qualitative perspective. Finally, results are summarised and categorised, and suggestions are made concerning the diverging choices made in translation and interpreting. The final section concentrates on further studies that could be carried out in the future, as well as on suggestions for corpus enlargement.

Feasibility study and flow scheduling optimization of a multi-product pipeline system

The first goal of this study is to analyse a real-world multiproduct onshore pipeline system in order to verify its hydraulic configuration and operational feasibility by constructing a simulation model step by step from its elementary building blocks that permits to copy the operation of the real system as precisely as possible. The second goal is to develop this simulation model into a user-friendly tool that one could use to find an “optimal” or “best” product batch schedule for a one year time period. Such a batch schedule could change dynamically as perturbations occur during operation that influence the behaviour of the entire system. The result of the simulation, the ‘best’ batch schedule is the one that minimizes the operational costs in the system. The costs involved in the simulation are inventory costs, interface costs, pumping costs, and penalty costs assigned to any unforeseen situations. The key factor to determine the performance of the simulation model is the way time is represented. In our model an event based discrete time representation is selected as most appropriate for our purposes. This means that the time horizon is divided into intervals of unequal lengths based on events that change the state of the system. These events are the arrival/departure of the tanker ships, the openings and closures of loading/unloading valves of storage tanks at both terminals, and the arrivals/departures of trains/trucks at the Delivery Terminal. In the feasibility study we analyse the system’s operational performance with different Head Terminal storage capacity configurations. For these alternative configurations we evaluated the effect of different tanker ship delay magnitudes on the number of critical events and product interfaces generated, on the duration of pipeline stoppages, the satisfaction of the product demand and on the operative costs. Based on the results and the bottlenecks identified, we propose modifications in the original setup.
