Abstract

Ein Riss im Rotor ruft eine lokale Steifigkeitsänderung hervor. Die vorliegende Arbeit ermittelt die Steifigkeitsänderung einer angerissenen Welle. Dazu wird ein Kohäsivzonenmodell eingesetzt. Das Modell wurde für die erste Rissöffnungsmode bei ebenem Verzerrungszustand in Abhängigkeit der Mehrachsigkeit des Spannungszustandes (Triaxialität) entwickelt. Außerdemwird das Kohäsivzonenmodell bei einem eindimensionalen Kontinuumsrotor als FE Modell ausgeführt.

Abstract

Model-based performance prediction systematically deals with the evaluation of software performance to avoid for example bottlenecks, estimate execution environment sizing, or identify scalability limitations for new usage scenarios. Such performance predictions require up-to-date software performance models. This book describes a new integrated reverse engineering approach for the reconstruction of parameterised software performance models (software component architecture and behaviour).

Abstract

Process measurement deals with the quantification of business process models using process model metrics. This book presents a theoretical framework for the prediction of external process model attributes (as, for example, error-proneness and understandabiltiy) based on internal (structural) attributes. The properties of proposed metrics are analyzed. A visualization technique for metric values is introduced and metrics for process model understandability and granularity are evaluated.

Abstract

The Java programming language provides safety and security guarantees such as type safety and its security architecture. They distinguish it from other mainstream programming languages like C and C++. In this work, we develop a machine-checked model of concurrent Java and the Java memory model and investigate the impact of concurrency on these guarantees. From the formal model, we automatically obtain an executable verified compiler to bytecode and a validated virtual machine.

Abstract

Auf internationaler Ebene wurden Ziele zur Minderung von Luftschadstoff- und klimarelevanten Emissionen vereinbart, deren Umsetzung den jeweiligen Unterzeichnerstaaten obliegt. Hierzu existieren zahlreiche umweltpolitische Instrumente, deren Effektivität und Effizienz jedoch schwer abschätzbar sind. Daher ist es das Anliegen des im vorliegenden Buch beschriebenen otello-Modellsystems, solche politischen Instrumente in ihren ökologischen und ökonomischen Wirkungsmechanismen zu bewerten.

Abstract

With the Karlsruhe Heart Model (KaHMo) we aim to share our vision of integrated computational simulation across multiple disciplines of cardiovascular research, and emphasis yet again the importance of Modelling the Human Cardiac Fluid Mechanics within the framework of the international STICH study. The focus of this work is on integrated cardiovascular fluid mechanics, and the potential benefits to future cardiovascular research and the wider bio-medical community.

Abstract

Supply chains consist of all processes which are needed in order to supply customers with the required products. Traditionally, supply chain management decisions are based on the economic performance of the involved parties. But in recent years, other criteria, such as quality, flexibility or the environment, have become important as well. Especially carbon emissions are high on the political agenda because they are considered to be a major cause of the greenhouse gas effect. In this work it is shown how the performance of supply chains can be evaluated considering both economic and environmental criteria. In particular, the work deals with dual sourcing in the context of the newsvendor model. The impact of environmental regulations (emission taxes and emission trading) on the decisions of companies is analysed.
