Les livres VI à VIII du traité des Simples de Galien. Tradition du texte et traduction annotée

La thèse se propose d’offrir la première traduction française des livres VI à VIII du traité des Simples de Galien portant sur la flore à intérêt pharmacologique. Afin de comprendre l’esprit et le but de l’œuvre, nous avons situé le médecin dans son contexte historique et culturel, le IIe siècle de notre ère, et nous avons fourni les données fondamentales de sa biographie et de sa production littéraire et, plus particulièrement, des textes pharmacologiques. Nous avons également étudié le rôle des plantes médicinales dans la médecine d’époque romaine, ainsi que les sources de l’œuvre, en particulier Dioscoride. Malgré le succès du traité au cours des siècles qui ont suivi, il n’a pas fait l’objet d’études approfondies et l’édition la plus récente demeure celle de K. G. Kühn du XIXe siècle. Une édition critique s’impose et c’est dans cette perspective que nous avons entrepris de dresser la liste définitive des manuscrits transmettant le texte galénique. Nous espérons que ces recherches permettront de comprendre un peu mieux l’importance des simples dans la pharmacologie de Galien et qu’elles seront un point de départ pour d’autres travaux sur le traité des Simples.

Ad summum bonum iter: revisione testuale e commento di Seneca, Epistulae morales ad Lucilium XLVIII, CXI.

Questa tesi di dottorato “Ad summum bonum iter. Revisione testuale e commento di Seneca, Epistulae morales ad Lucilium XLVIII, CXI” (relatore Prof. F. Citti), si propone di fornire un commento scientifico al testo latino di alcune Epistulae morales ad Lucilium (48 e 111), corredato da traduzione, note esegetiche di carattere lessicale, stilistico-retorico e storico-letterario e discussione delle principali problematiche testuali (testo di riferimento l'edizione critica di Reynolds, Oxonii 1965). Scopo della ricerca è approfondire e completare lo studio delle lettere 48 e 111 del carteggio, esaminato solo episodicamente e non sistematicamente, soffermandosi sugli aspetti filosofici salienti e sui motivi conduttori più significativi, come la critica senecana alla nimia subtilitas (tema presente soprattutto nelle cosiddette epistole dialettiche, connesse alle diverse forme di sillogismi e alle modalità di contestazione degli stessi), con particolare riferimento alle ambiguità derivanti dall'uso di termini in senso proprio e metalinguistico riflessivo e non riflessivo; la ricerca si sofferma inoltre sul linguaggio colloquiale, vicino a quello della commedia e della satira, utilizzato da Seneca per ridicolizzare i sillogismi stoici; sul tema dell'amicizia; sull'uso di citazioni e/o allusioni poetiche (virgiliana e non virgiliana), decontestualizzate e risemantizzate in funzione educativa e psicagogica, piegate ad esprimere il personale messaggio etico; sull'uso del lessico specialistico, proveniente da diversi ambiti semantici (giuridico, economico, militare, medico), applicato da Seneca alla parenesi filosofica e, soprattutto, sul rapporto tra lessico filosofico latino e modelli greci. Infine, oltre ad approfondire il motivo delle egestas temporis e i riferimenti diatribici contenuti nelle epistole, sono stati individuati e approfonditi alcuni topoi presenti.

Atlante digitale della Periegesi di Pausania: metodologia, implementazione e sviluppi

La tesi consiste nella descrizione del complessivo background storico-letterario, archeologico e digitale necessario per la realizzazione di un Atlante digitale dell’antica Grecia antica sulla base della raccolta e analisi dei dati e delle informazioni contenute nella Periegesi di Pausania. Grazie all’impiego degli applicativi GIS, ed in particolare di ArcGIS online, è stato possibile creare un database georiferito contenente le informazioni e le descrizioni fornite dal testo; ogni identificazione di un sito storico è stata inoltre confrontata con lo stato attuale della ricerca archeologica, al fine di produrre uno strumento innovativo tanto per a ricerca storico-archeologica quanto per lo studio e la valutazione dell’opera di Pausania. Nello specifico il lavoro consiste in primo esempio di atlante digitale interamente basato sull’interpretazione di un testo classico attraverso un processo di georeferenziazione dei suoi contenuti. Per ogni sito identificato è stata infatti specificato il relativo passo di Pausania, collegando direttamente Il dato archeologico con la fonte letteraria. Per la definizione di una tassonomia efficace per l’analisi dei contenuti dell’opera o, si è scelto di associare agli elementi descritti da Pausania sette livelli (layers) all’interno della mappa corrispondenti ad altrettante categorie generali (città, santuari extraurbani, monumenti, boschi sacri, località, corsi d’acqua, e monti). Per ciascun elemento sono state poi inserite ulteriori informazioni all’interno di una tabella descrittiva, quali: fonte, identificazione, età di appartenenza, e stato dell’identificazione.

L'enquete inquiete. Representer, connaitre, interpreter : poetiques et postures auctoriales (Zola, Capuana et Pardo Bazan)

Ma thèse interroge les formes, les modes et les enjeux liés à la notion d’« enquête » dans les discours et les poétiques d’Émile Zola, Luigi Capuana et Emilia Pardo Bazán. Il s'agit d’abord de prendre au sérieux l’ambition à l’« enquête totale » du roman naturaliste européen vers 1880, envisagée par le credo zolien du « tout dire », par l'idée de la forme « ancha, completa y perfecta » de Pardo Bazán et par l'éclectisme boulimique de Capuana. Corollairement, le lecteur de l’époque, demandeur de « récit », expérimente une pratique esthétique marquée par la porosité disciplinaire et la diversité de formats et de supports. Par l’épistémocritique, la sociocritique et la « sémiologie historicisée », il s’agit donc de questionner les relations entre scientifique et littéraire, fictionnel et factuel, vrai et faux, et leurs présupposés épistémologiques et idéologiques, qui sont définis et redéfinis par les trois auteurs à l’aune de leurs postures et de leurs stratégies d’affirmation spécifiques. En accord avec le « décloisonnement » disciplinaire à l’œuvre à l’époque, d’un point de vue de la réception ainsi que de la production, le corpus mobilisé rapproche des romans, des chroniques, des textes théoriques et critiques, mais aussi des textes « savants » produits ou consultés par les auteurs. À travers l’ensemble de ces perspectives, cette thèse tente d’éclairer, par une démarche comparée, la singularité historique d’une enquête « inquiète » dans le dernier tiers du XIXe siècle.

Virtual commissioning of automatic machines for mesh panels manufacturing

The purpose of this thesis is to present the concept of simulation for automatic machines and how it might be used to test and debug software implemented for an automatic machine. The simulation is used to detect errors and allow corrections of the code before the machine has been built. Simulation permits testing different solutions and improving the software to get an optimized one. Additionally, simulation can be used to keep track of a machine after the installation in order to improve the production process during the machine’s life cycle. The central argument of this project is discussing the advantage of using virtual commissioning to test the implemented software in a virtual environment. Such an environment is getting benefit in avoiding potential damages as well as reduction of time to have the machine ready to work. Also, the use of virtual commissioning allows testing different solutions without high losses of time and money. Subsequently, an optimized solution could be found after testing different proposed solutions. The software implemented is based on the Object-Oriented Programming paradigm which implies different features such as encapsulation, modularity, and reusability of the code. Therefore, this way of programming helps to get simplified code that is easier to be understood and debugged as well as its high efficiency. Finally, different communication protocols are implemented in order to allow communication between the real plant and the simulation model. By the outcome that this communication provides, we might be able to gather all the necessary data for the simulation and the analysis, in real-time, of the production process in a way to improve it during the machine life cycle.

Performance Analysis of Topological Quantum Error Correcting Codes

In the last few years there has been a great development of techniques like quantum computers and quantum communication systems, due to their huge potentialities and the growing number of applications. However, physical qubits experience a lot of nonidealities, like measurement errors and decoherence, that generate failures in the quantum computation. This work shows how it is possible to exploit concepts from classical information in order to realize quantum error-correcting codes, adding some redundancy qubits. In particular, the threshold theorem states that it is possible to lower the percentage of failures in the decoding at will, if the physical error rate is below a given accuracy threshold. The focus will be on codes belonging to the family of the topological codes, like toric, planar and XZZX surface codes. Firstly, they will be compared from a theoretical point of view, in order to show their advantages and disadvantages. The algorithms behind the minimum perfect matching decoder, the most popular for such codes, will be presented. The last section will be dedicated to the analysis of the performances of these topological codes with different error channel models, showing interesting results. In particular, while the error correction capability of surface codes decreases in presence of biased errors, XZZX codes own some intrinsic symmetries that allow them to improve their performances if one kind of error occurs more frequently than the others.

Position Errors Caused by GPS Height of Instrument Blunders

Height of instrument (HI) blunders in GPS measurements cause position errors. These errors can be pure vertical, pure horizontal, or a mixture of both. There are different error regimes depending on whether both the base and the rover both have HI blunders, if just the base has an HI blunder, or just the rover has an HI blunder. The resulting errors are on the order of 30 cm for receiver separations of 1000 km for an HI blunder of 2 m. Given the complicated nature of the errors, we believe it would be difficult, if not impossible, to detect such errors by visual inspection. This serves to underline the necessity to enter GPS HI's correctly.

Hungary and the eurozone crisis: a comedy of errors?

The spill-over of the global fi nancial crisis has uncovered the weaknesses in the governance of the EMU. As one of the most open economies in Europe, Hungary has suff ered from the ups and downs of the global and European crisis and its mismanagement. Domestic policy blunders have complicated the situation. This paper examines how Hungary has withstood the ups and downs of the eurozone crisis. It also addresses the questions of whether the country has converged with or diverged from the EMU membership, whether joining the EMU is still a good idea for Hungary, and whether the measures to ward off the crisis have actually helped to face the challenge of growth.

Offline Detection, Identification, and Correction of Branch Parameter Errors Based on Several Measurement Snapshots

This paper proposes a three-stage offline approach to detect, identify, and correct series and shunt branch parameter errors. In Stage 1 the branches suspected of having parameter errors are identified through an Identification Index (II). The II of a branch is the ratio between the number of measurements adjacent to that branch, whose normalized residuals are higher than a specified threshold value, and the total number of measurements adjacent to that branch. Using several measurement snapshots, in Stage 2 the suspicious parameters are estimated, in a simultaneous multiple-state-and-parameter estimation, via an augmented state and parameter estimator which increases the V - theta state vector for the inclusion of suspicious parameters. Stage 3 enables the validation of the estimation obtained in Stage 2, and is performed via a conventional weighted least squares estimator. Several simulation results (with IEEE bus systems) have demonstrated the reliability of the proposed approach to deal with single and multiple parameter errors in adjacent and non-adjacent branches, as well as in parallel transmission lines with series compensation. Finally the proposed approach is confirmed on tests performed on the Hydro-Quebec TransEnergie network.

Effects of the preventive and corrective adjustments in economical designs for online process control for attributes with misclassification errors

The procedure for online process control by attributes consists of inspecting a single item at every m produced items. It is decided on the basis of the inspection result whether the process is in-control (the conforming fraction is stable) or out-of-control (the conforming fraction is decreased, for example). Most articles about online process control have cited the stoppage of the production process for an adjustment when the inspected item is non-conforming (then the production is restarted in-control, here denominated as corrective adjustment). Moreover, the articles related to this subject do not present semi-economical designs (which may yield high quantities of non-conforming items), as they do not include a policy of preventive adjustments (in such case no item is inspected), which can be more economical, mainly if the inspected item can be misclassified. In this article, the possibility of preventive or corrective adjustments in the process is decided at every m produced item. If a preventive adjustment is decided upon, then no item is inspected. On the contrary, the m-th item is inspected; if it conforms, the production goes on, otherwise, an adjustment takes place and the process restarts in-control. This approach is economically feasible for some practical situations and the parameters of the proposed procedure are determined minimizing an average cost function subject to some statistical restrictions (for example, to assure a minimal levelfixed in advanceof conforming items in the production process). Numerical examples illustrate the proposal.
