To understand the problems in metamodeling, this work presents an investigation of bad smells in metamodels. The core contribution of this work is the reference structure. It enables design, evolut...

In this work, the authors analysed the co-dependency between models and analyses, particularly the structure and interdependence of artefacts and the feature-based decomposition and composition of ...

Der Erstellungsaufwand multimedialer Lernangebote kann durch die Wiederverwendung bestehender Materialien deutlich reduziert werden. Wie aber kann das Auffinden solcher wiederverwendbaren Lernresso...

This work presents an approach for the architecture analysis of energy efficiency for static and self-adaptive software systems. It introduces a modeling language that captures consumption characte...

In dieser Arbeit wird ein Ansatz zur adaptiven Umweltmodellierung betrachtet. Umweltmodelle für kognitive Systeme enthalten oft vorab definierte Domänenmodelle, die für unvorhergesehene Entitäten u...

In this work we suggest a meta access control model emulating established access control models by configuration and offering enhanced features like the delegation of rights, ego-centered roles, an...

The quality of enterprise software applications plays a crucial role for the satisfaction of the users and the economic success of the enterprises. Software applications with unsatisfying performan...

A main property of software-intensive technical systems is sustainability. Sustainable systems need to change continuously. A change to a system element can result in further changes to other syste...

This work focuses the recognition of complex human activities in video data. A combination of new features and techniques from speech recognition is used to realize a recognition of action units an...

Business processes and information systems evolve constantly and affect each other in non-trivial ways. Aligning security requirements between both is a challenging task. This work presents an auto...

The ADMD3 approach presented in this book enchances the architectural design documentation of decision via reuse of design patterns. It combines the support for evaluation of pattern application, s...

This cumulative habilitation thesis, proposes concepts for (i) modelling and analysing dependability based on architectural models of software-intensive systems early in development, (ii) decomposi...

This work introduces a novel approach to keep high-level component-based architecture models consistent with source code during software development and software evolution. The approach helps to av...

The software execution environment can play a crucial role when analyzing the performance of a software system. In this book, a novel approach for the automated detection of performance-relevant pr...

Quality attributes, such as performance or reliability, are crucial for the success of a software system and largely influenced by the software architecture. Their quantitative prediction supports ...

Three dimensional modeling and visualization of environments is an increasingly important problem. This work addresses the problem of automatic 3D reconstruction and we present a system for unsuper...

Unterwasserbilder besitzen meist eine schlechte Bildqualität, da diese von Farbverschiebungen, Unschärfe und einem milchig trüben Erscheinungsbild geprägt sind. In dieser Arbeit wird eine problemsp...

Cloud storage services and NoSQL systems typically offer only "Eventual Consistency", a rather weak guarantee covering a broad range of potential data consistency behavior. The degree of actual (in...

Wie können Menschen mit verschiedenen Kenntnissen und Erfahrungen Prozessmodelle in der digitalen Kommunikation verwenden und zugleich Systemunterstützung durch die beschriebenen Prozesse erhalten?...

Die sensorgestützte Sortierung ermöglicht die Trennung einzelner Partikel aus einem Materialstrom. In dieser Arbeit wird eine neue Gattung eines Schüttgutsortiersystems mit Flächenkamera erforscht....
