Der zunehmende Anteil von Software im Automobil stellt neue Herausforderungen an das Anforderungsmanagement in der Automobilindustrie: Dokumentation und Management unterschiedlicher Anforderungsartefakte auf unterschiedlichen Abstraktionsstufen, sowie die Wiederverwendung von Anforderungen unter Berücksichtigung gegebener Abhängigkeiten. 1 Einleitung Durch die zunehmende Komplexität von Systeme...

To what extent were Woodrow Wilson’s ideas about public administration informed by German organic political theory? Drawing on the writings of Wilson, Lorenz von Stein, and Johann K. Bluntschli on public administration, and comparing American and German primary sources, the author off ers insights into Wilson’s general concept of public administration, as well as his understanding of the politi...

We prove that for all 1 ≤ p ≤ ∞, p 6= 2, the L spaces associated to two von Neumann algebras M, N are isometrically isomorphic if and only if M and N are Jordan *-isomorphic. This follows from a noncommutative L Banach-Stone theorem: a specific decomposition for surjective isometries of noncommutative L spaces.

We prove a weak-type (1,1) inequality for square functions of noncommutative martingales that are simultaneously bounded in L and L. More precisely, the following non-commutative analogue of a classical result of Burkholder holds: ...

In this paper, we describe computer-aided authorship testing on the Middle High German (MHG) text Apollonius von Tyrland written by Heinrich von Neustadt (HvN) in the late 13th century. Being based on a Latin original, HvN is suspected to incorporate other sources into the translation. We investigate assumptions regarding a segmentation of this text into parts supposedly tracking back to differ...

We study a simple variant of the von Neumann model of an expanding economy, in which multiple producers produce goods according to their production function. The players trade their goods at the market and then use the bundles acquired as inputs for the production in the next round. We show that a simple decentralized dynamic, where players update their bids proportionally to how useful the inv...

We use the concept of a regular object with respect to another object in an arbitrary category, defined in [3], in order to obtain the transfer of regularity in the sense of Zelmanowitz between the categories R−mod and S−mod, when S is an excellent extension of the ring R. Consequently, we obtain a result of [5]: if S is an excellent extension of the ring R, then S is von Neumann regular ring i...

This work investigates if the von Kries adaptation can be generalized to deal with single colored patches. We investigate which colored patches can give statistically equivalent performance to a white patch for von Kries adaptation. The investigation is then extended to couples of colors, and the analysis of the characteristics of the colors forming the couples is carried out. We focus here on ...

We introduce “embedding dimensions” of a family of generators of a finite von Neumann algebra when the von Neumann algebra can be faithfully embedded into the ultrapower of the hyperfinite II1 factor. These embedding dimensions are von Neumann algebra invariants, i.e., do not depend on the choices of the generators. We also find values of these invariants for some specific von Neumann algebras.
