Bokkapitel (refereegranskat)abstract
- We discuss thermal fluid-structure interaction processes, where a simulation of the time-dependent temperature field is of interest. Thereby, we consider partitioned coupling schemes with a Dirichlet-Neumann method. We present an analysis of the method on a model problem of discretized coupled linear heat equations. This shows that for large quotients in the heat conductivities, the convergence rate will be very small. The time dependencymakes the use of time-adaptive implicitmethods imperative. This gives rise to the question as to how accurately the appearing nonlinear systems should be solved, which is discussed in detail for both the nonlinear and linear case. The efficiency of the resulting method is demonstrated using realistic test cases.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The text is a compilation of an e-mail dialogue between composer Ole Lützow-Holm and guitarist Stefan Östersjö. It contemplates a collaboration between the two, resulting in a musical composition for 11-stringed alto guitar named Traces of Oblivion. The dialogue format seemed coherent, since the entire composition and performance process was based on the principle of call and response. The conversation navigated by the concept of a stream of consciousness, pursuing no specific target other than that of being vigilantly awake in search of aspects, be they minor or major, that might (or might not) shed light on the transient repercussions engendered by our efforts to articulate another music.

Traces of Oblivion Dialogue (audio paper)

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The audio paper features a spoken, edited version of a dialogue between composer Ole Lützow-Holm and guitarist Stefan Östersjö, additionally published as a written paper in the same anthology. The voiced material – contemplating a collaboration between the two that resulted in a musical composition for 11-stringed alto guitar named Traces of Oblivion – is partly embedded in, partly punctuated by fragments of the music.
