Affine flag manifolds are infinite dimensional versions of familiar objects such as Graßmann varieties. The book features lecture notes, survey articles, and research notes - based on workshops held in Berlin, Essen, and Madrid - explaining the significance of these and related objects (such as double affine Hecke algebras and affine Springer fibers) in representation theory (e.g., the theory of symmetric polynomials), arithmetic geometry (e.g., the fundamental lemma in the Langlands program), and algebraic geometry (e.g., affine flag manifolds as parameter spaces for principal bundles). Novel aspects of the theory of principal bundles on algebraic varieties are also studied in the book.

In einem hoch dynamischen Markt wie dem für Logistikdienstleistungen müssen Anbieter kontinuierlich ihr Geschäftsmodell auf Nachhaltigkeit prüfen und den Kundenanforderungen anpassen. In der Praxis intensiv diskutiert wird das Modell des Fourth Party Logistics 4PL-ProvidingTM – verstanden als gebündeltes Angebot an strategischen und operativen SCM-Dienstleistungen –, das insbesondere für Logistikdienstleistungsunternehmen interessant ist, die bereits Systemdienstleistungen anbieten (Kontraktlogistikdienstleister). Alexander Schmitt entwickelt ein strategisches Bewertungskonzept für Geschäftsmodelle in der Logistikdienstleistungsindustrie. Es ist Grundlage für eine strukturierte, praxisbezogene Untersuchung der Nachhaltigkeit des 4PL-ProvidingTM aus verschiedenen Perspektiven, z.B. anhand von Fallstudien und einer großzahligen Kundenbefragung. Der Autor weist nach, dass 4PL-ProvidingTM als strategische Option z.Zt. zwar noch ein geringes Erfolgspotenzial für Kontraktlogistikdienstleister aufweist, dass diese jedoch wegen ihrer ressourcenbedingten sehr guten Ausgangssituation (u.a. durch detailliertes branchenspezifisches Ausführungswissen) die eigenen Möglichkeiten eines 4PL-ProvidingTM ständig prüfen sollten, um rechtzeitig Marktchancen für ihr Geschäft zu erkennen.

In Monitoring Adaptive Spoken Dialog Systems, authors Alexander Schmitt and Wolfgang Minker investigate statistical approaches that allow for recognition of negative dialog patterns in Spoken Dialog Systems (SDS). The presented stochastic methods allow a flexible, portable and  accurate use.  Beginning with the foundations of machine learning and pattern recognition, this monograph examines how frequently users show negative emotions in spoken dialog systems and develop novel approaches to speech-based emotion recognition using hybrid approach to model emotions. The authors make use of statistical methods based on acoustic, linguistic and contextual features to examine the relationship between the interaction flow and the occurrence of emotions using non-acted  recordings several thousand real users from commercial and non-commercial SDS. Additionally, the authors present novel statistical methods that spot problems within a dialog based on interaction patterns. The approaches enable future SDS to offer more natural and robust interactions. This work provides insights, lessons and  inspiration for future research and development, not only for spoken dialog systems, but for data-driven approaches to human-machine interaction in general.

Um die gestiegenen Anforderungen an elektrische Antriebe im Hinblick auf Zuverlässigkeit und Sicherheit zu erfüllen, wurden in den letzten Jahren PHIL-Emulatoren für elektrische Maschinen entwickelt. Aufgrund funktionaler Einschränkungen können diese Emulatoren das Verhalten einer realen Maschine jedoch bisher nicht äquivalent nachbilden. Die vorliegende Arbeit setzt an diesem Punkt an und zeigt auf, wie ein PHIL-Prüfstand konzipiert sein muss, um eine Synchronmaschine ganzheitlich nachzubilden.In order to fulfill the increased requirements for electrical drives in terms of reliability and safety, PHIL emulators for electrical machines have been developed over the past years. However, up to now, these emulators are not suitable to emulate the operating behavior of a real machine equivalently. This study starts at this point and identifies the ideal design of a PHIL test bench to emulate a synchronous machine holistically.
