1. Few is Just Enough! : Small Model Theorem for Parameterized Verification and Shape Analysis
Abstract : This doctoral thesis considers the automatic verification of parameterized systems, i.e. systems with an arbitrary number of communicating components, such as mutual exclusion protocols, cache coherence protocols or heap manipulating programs. The components may be organized in various topologies such as words, multisets, rings, or trees. READ MORE

2. Semantics, Decision Procedures, and Abstraction Refinement for Symbolic Trajectory Evaluation
Abstract : The rapid growth in hardware complexity has led to a need for formal verification of hardware designs to prevent bugs from entering the final silicon. Model-checking is a verification method in which a model of a system is checked against a property, describing the desired behaviour of the system over time. READ MORE

3. Validation of a Standard- and Metric-Based Software Quality Model : Creating the Prerequisites for Experimentation
Abstract : Our long term research goal is to validate a standard- and metric-based software quality model. Today, ambiguous metric definitions lead to incomparable implementation variants in tools. READ MORE

4. Dynamic Abstraction for Interleaved Task Planning and Execution
Abstract : It is often beneficial for an autonomous agent that operates in a complex environment to make use of different types of mathematical models to keep track of unobservable parts of the world or to perform prediction, planning and other types of reasoning. Since a model is always a simplification of something else, there always exists a tradeoff between the model’s accuracy and feasibility when it is used within a certain application due to the limited available computational resources.

5. An Approach to Diagnosability Analysis for Interacting Finite State Systems
Abstract : Fault isolation is the process of reasoning required to find the cause of a system failure. In a model-based approach, the available information is a model of the system and some observations. READ MORE
