Ein zentrales Versprechen von BigData ist die Lösung von Problemen bezüglich scheinbar unmöglicher Datenvolumina und Änderungsfrequenzen. Die typischen Beispiele für erfolgreiche BigData Anwendungen decken dabei Probleme ab, die mit traditionellen Enterprise-Architekturen und -Technologien trotz Optimierung dieser Architekturen und Technologien kläglich scheitern – oder mit gutem Grund – überha...

Users are increasingly inundated with small devices with communication and storage capabilities. Unfortunately, the user is still responsible for reconciling all of the devices whenever a change is made. We present Footloose, a usercentered data store that can share data and reconcile conflicts across diverse devices. Footloose is an optimistic system based on physical eventual consistency—cons...

Abstract. An eventual property of a matrix M ∈ C is a property that holds for all powers M, k ≥ k0, for some positive integer k0. Eventually positive and eventually nonnegative matrices have been studied extensively, and some results are known for eventually r-cyclic matrices. This paper introduces and establishs properties of eventually reducible matrices, establishs properties of the eigenstr...

Mobile devices commonly access shared data stored on a server. To ensure responsiveness, many applications maintain local replicas of the shared data that remain instantly accessible even if the server is slow or temporarily unavailable. Despite its apparent simplicity and commonality, this scenario can be surprisingly challenging. In particular, a correct and reliable implementation of the com...
