Kraus e/o Shakespeare. Intertestualità in prospettiva: tradurre, citare, inscrivere

The thesis focuses on Karl Kraus’s rewritings of some Shakespeare plays and copes with the concepts of “translation” and “quotation” as commensurable forms of intertextuality. Building his Shakespeare’s Bearbeitungen as a montage of quotations of previous German translations, Karl Kraus creates a new kind of hybrid intertextuality that goes beyond the boundaries between quotation and translation. In my opinion, Karl Kraus understands quotation and translation as spatial concepts: in his rewritings he puts Shakespeare’s text into his geometrical and critical “perspective”. The thesis focuses also on the evolution of quotation and translation in Karl Kraus’s work: even maintaining their satirical and destruens function, they develop an “affirmative” role and are used in order to redefine the literary canon. The thesis investigates this form of intertextuality from a comparative point of view, referring to the translation studies (Hermans, Bassnett, Lefevere, Apel, Berman, Meschonnic), theories of intertextuality (Genette, Barthes, Worton, Orr), studies on quotation and montage (Compagnon; Möbius, Hage), and studies on Karl Kraus (Kraft, Ribeiro, Scheichl, Fischer, Timms, Canetti and the famous essay of Walter Benjamin). It also contains a survey of Theater der Dichtung’s historical framework and several comparisons between Karl Kraus’s and other early 20th translations of Shakespeare’s plays.

Partial Discharge Phenomena in Converter and Traction Transformers: Identification and Reliability

After the development of power electronics converters, the number of transformers subjected to non-sinusoidal stresses (including DC) has increased in applications such as HVDC links and traction (electric train power cars). The effects of non-sinusoidal voltages on transformer insulation have been investigated by many researchers, but still now, there are some issues that must be understood. Some of those issues are tackled in this Thesis, studying PD phenomena behavior in Kraft paper, pressboard and mineral oil at different voltage conditions like AC, DC, AC+DC, notched AC and square waveforms. From the point of view of converter transformers, it was found that the combined effect of AC and DC voltages produces higher stresses in the pressboard that those that are present under pure DC voltages. The electrical conductivity of the dielectric systems in DC and AC+DC conditions has demonstrated to be a critical parameter, so, its measurement and analysis was also taken into account during all the experiments. Regarding notched voltages, the RMS reduction caused by notches (depending on firing and overlap angles) seems to increase the PDIV. However, the experimental results show that once PD activity has incepted, the notches increase PD repetition rate and magnitude, producing a higher degradation rate of paper. On the other hand, the reduction of mineral oil stocks, their relatively low flash point as well as environmental issues, are factors that are pushing towards the use of esters as transformer insulating fluids. This PhD Thesis also covers the study of two different esters with the scope to validate their use in traction transformers. Mineral oil was used as benchmark. The complete set of dielectric tests performed in the three fluids, show that esters behave better than mineral oil in practically all the investigated conditions, so, their application in traction transformers is possible and encouraged.
