Abstract

Performance modelling can require substantial effort when creating and maintaining performance models for software systems that are based on existing software. Therefore, this thesis addresses the challenge of performance prediction in such scenarios. It proposes a novel goal-oriented method for experimental, measurement-based performance modelling. We validated the approach in a number of case studies including standard industry benchmarks as well as a real development scenario at SAP.

Abstract

Natural language is the main means to state requirements in software development. Today, requirements engineering is the first and main part of the software development and is mainly manual. These processes are error prone and depend on the experience and skills of the requirements analyst. The goal of this work is to automate parts of these manual processes with software tools.

Abstract

Die vorliegende Abhandlung untersucht die methodische und systematische Herangehensweise an die Entwicklung dienstorientierter Anwendungen im Web Engineering. Dabei wird deren architekturelle Betrachtung in den Vordergrund gerückt, die auf der Grundlage autonomer, wiederverwendbarer Komponenten in Form von Web Services basiert. Dazu werden dedizierte Modelle, Methoden und Werkzeuge entlang dieser - an Web-Standards orientierten - Architektur entwickelt.

Abstract

The Grid provides access to distributed computational capabilities such as processors or storage space. One of the key problems is deciding which jobs are to be allocated to which resources at what time. In this context, the use of market mechanisms is a promising approach to solve these problems. This book proposes an auction mechanism for allocating computer resources which have multiple quality attributes and time constraints.The auction is evaluated by means of a numerical simulation.

Abstract

Elektronische Märkte haben in den letzten Jahren in vielen Bereichen auch des täglichen Lebens zunehmend an Bedeutung gewonnen. Um im Konkurrenzkampf bestehen zu können, sind die Anbieter elektronischer Marktplätze wie Ebay oder die Deutsche Börse gezweungen bestehende Märkte zu verbessern und neue Marktformen zu entwickeln. Ein wichtiger Teil dieses Market-Engineering-Prozesses beseht aus der abschließenden Analyse und Evaluation neu erstellter oder veränderter Märkte- Eine etablierte Untersuchungsmethodik neben der theoretischen Betrachtung und Simulationen stellen dabei Laborexperimente dar.Dieses Buch stellt ein Experimentalsystem vor, mit dem Laborexperimente im Marktumfeld schnell und einfach entworfen, konfiguriert und durchgeführt werden können. Mit Hilfe dieses Experimentalsystems wird anschließend untersucht, welchen Einfluss die Benutzungsoberfläche eines Handelssystems auf das Verhalten der Matrktteilnehmer und damit auch auf das Marktergebnis haben kann.

Abstract

Heutzutage werden E/E-Architekturen modellbasiert entworfen, um in der Fahrzeugentwicklung frühzeitig den Reifegrad für die fahrzeugweite Vernetzung und Integration von Elektrik, Elektronik und Software abzusichern. Das methodische Konzept und die praktische Umsetzung durch das Modulorientierte Produktlinien Engineering ermöglicht eine Erhöhung der Modellierungseffizienz und der Modellqualität sowie eine Anwenderunterstützung für die Modellierung der komplexen E/E-Architekturmodelle.

Abstract

The aim of this work was to identify the patterns that can induce heating around implanted cardiac pacemakers during MRI and to develop strategies to counteract them. Two approaches were taken: computer simulations of the occurring electromagnetic field distributions and in-vitro experiments using phantoms in real MRI devices, both for conventional bore-hole and new open MRI systems. Using the open MRI, the observed heating could be reduced significantly.

Abstract

Two aspects of anthropogenic impacts on the atmosphere are investigated using means of numerical weather prediction. A case study is conducted to estimate the impact of such artificial clouds on the incoming solar radiation at the Earth's surface with special regard to photovoltaic power production. Furthermore, simulations are performed to assess the efficacy of injecting particles into the Arctic troposphere with the aim of modifying cirrus clouds for counteracting global warming.
