We present a novel, real-time system, called Harmonic Navigator, for exploring the harmonic space in J.S. Bach Chorales. This corpus-based environment explores trajectories through harmonic space. It supports visual exploration and navigation of harmonic transition probabilities through interactive gesture control. These probabilities are computed from musical corpora (in MIDI format). Herein w...

We developed a new Bach-type reaction in the presence of oxy-hemoglobin as an oxygen supplier to synthesize polyazobenzene by traditional Bach reaction. The resultant product is form polymeric dye/hemoglobin copolymer. advantage this research that it involves using function biomolecules, well formation plastics and biomaterials. bio-based material may have good affinity with life forms, which l...

Die Ausführungen werden von der Frage geleitet, wie und inwieweit Bachs Handeln sozialen Praxis seiner Zeit her verstehbar wird welche Rückschlüsse daraus zu ziehen sind. Im Vordergrund steht die Analyse des sogenannten "Präfektenstreits", welcher zwar ein fester Bestandteil Bach-Biographik ist, aber in Forschung eher stiefmütterlich behandelt wird. Entscheidend ist weniger Schilderung Vorgangs...

In this paper we characterize the source-free Einstein-Maxwell spacetimes which have a trace-free Chevreton tensor. We show that this is equivalent to the Chevreton tensor being of pure-radiation type and that it restricts the spacetimes to Petrov types N or O. We prove that the trace of the Chevreton tensor is related to the Bach tensor and use this to find all Einstein-Maxwell spacetimes with...
