Transtextualidade na tradução de "Der mann im fahrstuhl / The mann in the elevator"

In an age where Babel has turned into transcultural communication, an interlingual approach – i.e. in English and in French – to the translating process from German to Portuguese appeared pertinent. Aiming at a refinement of the translating competence, this process consists in contrasting different linguistic and literary strategies through an intercultural and multi-etymological perspective. Thus, we settled upon Heiner Müller‘s play Der Auftrag. Erinnerung an eine Revolution (1980), on which the composer Heiner Goebbels has based himself to textually and musically dramatize an excerpt, Der Mann im Farhstuhl / The Man in the Elevator. A transcription of such excerpt in its source language, German, as well as its translation into English (Carl Weber, 1984, Performing Arts Publications, New York) and French (Jean Jourdheuil, Heinz Schwarzinger, Editions Minuit, Paris) can be found in the booklet that accompanies the CD – edited in 1988 by ECD (München: Records GmbH). It should be emphasized that such a creation allows a framing of Müller‘s text into a musical scenography and, therefore, encourages an intersemiotic contrast. This experience enabled us to come up with a unique imagery of Müller‘s piece of writing, by means of its dramatic and musical conversion and, simultaneously, lead us to stretch our textual consciousness to a multitude of intra-, extra- and interlinguistic elements.

Complex-order forced van der Pol oscillator

In this paper we consider a complex-order forced van der Pol oscillator. The complex derivative Dα1jβ, with α, β ∈ ℝ+, is a generalization of the concept of an integer derivative, where α = 1, β = 0. The Fourier transforms of the periodic solutions of the complex-order forced van der Pol oscillator are computed for various values of parameters such as frequency ω and amplitude b of the external forcing, the damping μ, and parameters α and β. Moreover, we consider two cases: (i) b = 1, μ = {1.0, 5.0, 10.0}, and ω = {0.5, 2.46, 5.0, 20.0}; (ii) ω = 20.0, μ = {1.0, 5.0, 10.0}, and b = {1.0, 5.0, 10.0}. We verified that most of the signal energy is concentrated in the fundamental harmonic ω0. We also observed that the fundamental frequency of the oscillations ω0 varies with α and μ. For the range of tested values, the numerical fitting led to logarithmic approximations for system (7) in the two cases (i) and (ii). In conclusion, we verify that by varying the parameter values α and β of the complex-order derivative in expression (7), we accomplished a very effective way of perturbing the dynamical behavior of the forced van der Pol oscillator, which is no longer limited to parameters b and ω.

Complex order van der Pol oscillator

In this paper a complex-order van der Pol oscillator is considered. The complex derivative Dα±ȷβ , with α,β∈R + is a generalization of the concept of integer derivative, where α=1, β=0. By applying the concept of complex derivative, we obtain a high-dimensional parameter space. Amplitude and period values of the periodic solutions of the two versions of the complex-order van der Pol oscillator are studied for variation of these parameters. Fourier transforms of the periodic solutions of the two oscillators are also analyzed.

Analysis of the Van der Pol oscillator containing derivatives of fractional order

In this paper a modified version of the classical Van der Pol oscillator is proposed, introducing fractional-order time derivatives into the state-space model. The resulting fractional-order Van der Pol oscillator is analyzed in the time and frequency domains, using phase portraits, spectral analysis and bifurcation diagrams. The fractional-order dynamics is illustrated through numerical simulations of the proposed schemes using approximations to fractional-order operators. Finally, the analysis is extended to the forced Van der Pol oscillator.

Tradução do conto de Peter Handke “Das Umfallen der Kegel von einer bäuerlichen Kegelbahn”

O conto aqui traduzido é um exemplo acabado de desconstrucionismo, sobretudo conseguido através da menorização do papel do narrador, constantemente desautorizado pelas personagens, que o interrompem e o contradizem. Assim, alguns segmentos aparentemente incongruentes não o são de facto. Na tarefa de tradução deste conto, mantivemos as características de descontrução do texto de partida, pelo que quaisquer aparentes incoerências são inerentes ao texto original e não erros de tradução.
