The slow growth of computer-integrated manufacturing is attributed to the complexity of designing and implementing their control and integration software. This article expands on a methodology for designing and implementing this software that was introduced in [16]. The goal of this methodology is to build flexible and reusable control and integration software for computer-integrated manufactur...

Die Entwicklung neuer elektronischer Märkte ist eine anspruchsvolle Aufgabe. Das Market Engineering definiert dafür einen strukturierten Entwicklungsprozess. Vor der Einführung der neu entwickelten Märkte im Rahmen des Market Engineering Prozesses müssen diese aber erst getestet und evaluiert werden. Dazu können Laborexperimente einen wichtigen Beitrag leisten. Dieses Paper beschreibt das meet2...

Paleomagnetic data from more than 250 samples of the lower part of the Waterberg Group (Nylstroom Subgroup) are reported in order to reevaluate the apparent polar wander path (APWP) of the Kaapvaal craton during the Paleoproterozoic Era. Our study broadly confirms the established APWP, but reveals some previously unidentified complexities in the time interval ~2.05 Ga to ~1.87 Ga. A primary rem...

Die informationstechnische Infrastruktur sehr vieler Industriebetriebe ist durch die gleichzeitige Verwendung mehrerer spezialisierter Anwendungsprogramme, die auf die Lösung bestimmter Probleme zugeschnitten sind, geprägt [Abe90]. Besonders im Computer Integrated Manufacturing (CIM) ist man auf solche Speziallösungen für einzelne Aufgabenbereiche wie z.B. PDM, PPS oder CAD, die in der Regel ke...

We show that weak-coupled two-dimensional dilaton gravity on Anti-de Sitter space can be described by the dynamics of an open string. Neumann and Dirichlet boundary conditions for the string lead to two different realizations of the Anti-de Sitter/Conformal Field Theory correspondence. In particular, in the Dirichlet case the thermodynamical entropy of two-dimensional black holes can be exactly...

To deliver complex functionalities in a cost effective manner, distributed manufacturing systems should ideally be based on standard interoperable components and be flexible and easily extensible. At the same time, systems must be demonstrably safe and reliable. In this paper, we argue that to balance these conflicting demands effective safety analysis techniques are required that partly automa...

In a manufacturing perspective, a successful product introduction requires attention for the product quality, the introduction process, manufacturing scale and ICT support for manufacturing processes. The patterns that have been found in the product lifecycle provide information on what product introduction scenarios need to be supported. If these scenarios are considered upfront, they can aid ...

This paper presents the aerodynamic design and economical evaluation of a 200 kW site specific wind turbine for the province of Semnan in Iran. By designing site specific wind turbines, the cost of energy which is calculated out of the annual energy production and also the cost of manufacturing the rotor are minimized. The aerodynamic design is based on the well-known blade element momentum...
