Modernity’s emblematic faith in technology, the doctrine of progress, the centrality of instrumental reason, the sanctity of individual freedom, the denial of the sacred – all of these have been suggested as sources of an environmentally destructive cultural tendency. The common ground uniting all of these beliefs is the secular worldview, a historically specific story about reduction of realit...

Crafting satisfying narratives while preserving player freedom is a longstanding challenge for computer games. The quest structure used by many games allows players to experience content nonlinearly, but risks creating disjointed stories when side quests only minimally integrate with the main story. We propose a flexible, scene-based emergent story system that reacts to the player’s actions whi...

The hurricane remains one of the outstanding enigmas of fluid dynamics. This is so, in part, because the phenomenon is comparatively difficult to observe and because no laboratory analogue has been discovered. To this it must be added that hurricanes have received surprisingly little attention from the theoretically inclined fluid dynamicist, perhaps owing to an understandable tendency to avoid...

According to Hans Kamp and Frank Vlach, the two-dimensional tense operators “now” and “then” are ineliminable in quantified tense logic. This is often adduced as an argument against tense logic, and in favor of an extensional account that makes use of explicit quantification over times. The aim of this paper is to defend tense logic against this attack. It is shown that “now” and “then” are eli...

In this contribution we propose an analogue receiver that can perform turbo detection inMIMO systems. We present the case for a receiver that is built from nonlinear analogue devices, which perform detection in a “free-flow” network (no notion of iterations). This contribution can be viewed as an extension of analogue turbo decoder concepts to include MIMO detection. These first analogue implem...

Authentication is a process of verifying the identity of someone (a user, device, or an entity) who wants to access data, resources, or applications. Validating the identity shall establish a trust relationship for further interactions. Authentication even enables the accountability by making it possible to integrate both access and actions to specific identities. There are a huge number of tec...

Web-based Trainings (WBTs) sind im Zuge der „E-LearningErnüchterung“ zum Teil stark in die Kritik geraten. Andererseits stellen sie nach wie vor ein wichtiges Instrument zur Realisierung der erheblichen E-LearningPotenziale dar, insbesondere wenn qualitativ hochwertige Lernmaterialien erwartet werden. Eine erfolgreiche Gestaltung, Produktion und Verwendung von WBTs ist jedoch mit zahlreichen He...
