Distributed Acoustic Signal Processing over Wireless Sensor Networks
We consider an acoustic sensor network, where different applications, such as source separation and extraction, should be executed. A straightforward solution might be to transport all data to a gateway node and process it there. This is, however, not necessarily the best solution (data rate bottlenecks, large latency for big acoustic data). We ...

TRR 191 - Symplectic structures in geometry, algebra and dynamics
Since their inception, the study of symplectic structures and the applications of symplectic techniques (as well as their odd-dimensional contact geometric counterparts) have benefited from a strong extraneous motivation. Symplectic concepts have been developed to solve problems in other fields that have resisted more traditional approaches, or ...

TRR 191 - Symplectic methods of infinite dimensional systems (Subproject B06)
Symplectic methods lead to significant progress also for infinite-dimensional dynamical systems (mostly in the form of PDEs). This project considers two instances of such systems, and we intend to (i) construct new solutions of the Einstein equations using integrability methods (via symmetries of the spacetime); and (ii) significantly expand the ...

TRR 191 - Derived categfories of singular curves (Subproject A07)
In this project, we shall apply techniques of algebraic geometry and homological algebra (derived categories, Fourier-Mukai transforms, vector bundles on possibly singular Riemann surfaces) to study problems of geometric analysis. In particular, we shall investigate Bochner Laplacians and kernel functions (Bergman and Szeg? kernels) attached to ...

infantaticum, regina, imperatrix - Erbe und Herrschaft von T?chtern spanischer Herrscher im 10. - 12. Jahrhundert (Arbeitstitel, Promotionsprojekt Dania Lins)
According to a document from 1157, Sancha, the sister of King Alfonso VII, made an introductory donation to the cathedral of Zamora and the church of San Miguel de Mercadillo with the words "Ego Sancia regina, comitis Raimundi et Vrrache regine ragina proles ...". A typical but in this case remarkable activity for the Spanish High Middle Ages; as ...

AUTOMATISMEN UND STRUKTUR: ZU PROZESSEN DER AUFL?SUNG UND ZERSETZUNG (INT. TAGUNG AN DER UNIVERSIT?T PADERBORN)
Zum Abschluss des Graduiertenkollegs ?Automatismen“ wurde auf der international besetzten Konferenz die Forschungsperspektive der Automatismenforschung gleichsam von der Gegenseite her aufgegriffen. Nicht mehr Ph?nomene der Strukturentstehung au?erhalb geplanter Prozesse standen zur Diskussion, sondern umgekehrt die Frage, ob und inwiefern ...

Ger?uscherkennung mit begrenzter ?berwachung über Sensornetzwerke
A mismatch between training and test data statistics can result in a significant degradation of performance of machine learning systems. For sound recognition in acoustic sensor net?works (ASNs) this is a significant issue because of the huge number and variability of sounds and acoustic environments, and because of the large variety of sensor ...

Akustische Sensornetze Acoustic Sensor Networks Research Group
This Research Unit investigates solutions and limitations for acoustic signal processing and classification over coustic sensor networks. We aim to tackle current shortcomings and to develop a common platform which will make ASNs more adaptive to the variability of acoustic environments and sensor configurati?ons, less dependent on supervision, and ...
