Methods and Applications in Interactive Broadcasting

Interactive TV technology has been addressed in many previous works, but there is sparse research on the topic of interactive content broadcasting and how to support the production process. In this article, the interactive broadcasting process is broadly defined to include studio technology and digital TV applications at consumer set-top boxes. In particular, augmented reality studio technology employs smart-projectors as light sources and blends real scenes with interactive computer graphics that are controlled at end-user terminals. Moreover, TV producer-friendly multimedia authoring tools empower the development of novel TV formats. Finally, the support for user-contributed content raises the potential to revolutionize the hierarchical TV production process, by introducing the viewer as part of content delivery chain.

The effect of demand distributions on the performance of inventory policies

Inventory policies provide instructions on how to calculate stock levels and order quantities. This paper examines the effect of the demand distribution on the performance of several well-known policies. Their performance is compared in terms of achieved service levels. As a conclusion from these comparisons, a nonparametric demand model is proposed to be used in inventory policies.

Energy and weight reduction in hoisting systems with magnetic traction sheaves

At the Chair of Logistics Engineering, TU Dresden, a particular focus is research and development of magnetic traction sheaves. Therein the main fundamentals of these special sheaves are determined for applications in different fields such as elevators, several kinds of winches, hoists and cranes. In the current research project “energy balance of magnetic traction sheaves”, the dynamic behaviour of systems with magnetic traction sheaves was investigated. The research focused on theoretical and practical examinations of energy balance. Moreover, a new approach for dimensioning magnetic traction sheave systems is presented. It is a project of the Research Foundation Intralogistics / Material Handling and Logistics (IFL), which is funded through the AiF under the program of Industrial Collective Research for SMEs (IGF) by the Federal Ministry of Economics and Technology (BMWi).

Führungsbauteile aus faserverstärkten Kunststoffen in intralogistischen

In vielen Anwendungen der Intralogistik lassen sich Führungssysteme mit Stützrollen finden, die hohen Belastungen ausgesetzt sind. Hierbei werden oftmals Profilträger aus Stahlwerkstoffen als führende Bauteile eingesetzt. Deren Bewegung erfordert aufgrund der hohen Eigenmassen einen erheblichen Energiebedarf. Im vorliegenden Artikel wird die Entwicklung von derartigen Komponenten aus faserverstärkten Kunststoffen beschrieben. Der Fokus liegt auf der Eintragung hoher Kontaktkräfte in das Bauteil. Es werden die notwendigen Anforderungen dargestellt sowie die Entwicklung eines speziellen Rollenprüfstandes erläutert. Zudem beinhaltet der Artikel die systematische Entwicklung neuer Funktionselemente und die Herleitung einer Methodik zur Untersuchung der Belastbarkeit des faserverstärkten Kunststoffes beim Einwirken einer Rolle als Teilergebnisse des Forschungsvorhabens.
