RESEARCH

Software Development for Android Smartphones using Sensors (since 2010)
We explore the development of socalled Apps for Android Smartphones that use the smartphone's sensors incuding the GPS unit. Our goal is to develop high-quality software. The Lab Ubiquitous and Web-Applications at Hochschule Offenburg supports research and teaching for smartphones.
- Motivation. Accelerometers, Gyrometer and Compass can be used in tracking the movement and orientation of the smartphone device. This can be used for controlling an application by moving the smartphone with the hand. If a single sensor is used for computing the movement, measurement errors accumulate. Moreover, each line of code contributes to the latency of the reaction. Developing code for sensors require a deeper understanding of physics and mathematics. We try to minimize measurement errors by combining several sensors in software while keeping the latency to a minimum. This approach is also known as “Sensor Fusion”, for hardware as well as for software.
- Sensor Fusion Algorithm. We propose a multithreaded Java architecture for Android smartphones that computes quaternion-based rotations representing the device orientation as an interpolation of accelerometer, compass (magnetometer) and gyrometer. Our sensor fusion is based on a complementary filter and on spherical linear interpolation (SLERP). Video (19 MB, 39 sec.)
- Feature Management. Variability accross different smartphones can be captured by a software product line approach. We investigate the modeling of sensor features and display features and the code generation from such models.
Analysis of Behavioral Models with Graph Transformations (since 2005)
For model driven development, checking the consistency of models is crucial. Together with Leen Lambers and Gabi Täntzer, we developed an extension to activity diagrams using pre- and post-conditions for each activity. This model is translated into a graph transformation system. A set of rule sequences derived from the activity diagram can then be checked for consistency. We also take into account object flow in activity diagrams. In future, we plan to apply this research to service-oriented models like BPEL. A specialization of this research is the analysis of aspect-oriented model weaving which I exploited together with Mattia Monga and Gabi Täntzer. In 2011 we have been invited to author a chapter in the Springer Book on Aspect-Oriented Requirements Engineering.
EU Project NEXOF RA - NESSI Open Service Framework Reference Architecture (2007-2008)
The NESSI consortium aims a developing a reference architecture for interoperable and open service-oriented systems in the project NEXOF RA, integrating results from other NESSI projects.
BMBF Project TOPPrax (2004-2006)
In this project, initiated and led by Stephan Herrmann, we developed the aspect-oriented language and tool ObjectTeams/Java. We evaluated the technology together with an SME. We developed metrics and also applied the technology to software product lines. Finally, we carried out an experimental case study with students comparing Java to aspect-oriented programming.
Project FASOP (2002)
I was a visiting researcher at Lancaster University, working on a project on foundations of Aspect-Oriented Programming led by Awais Rashid. We identified initial dimensions of AOP and a model of runtime program inspection.
Project XCool (1998-1999)
At the University of Paderborn, I supervised a one year students project together with Annika Wagner, in which we developed the domain specific aspect-oriented programming language XCool for the synchronization of Java threads. PDF

DISSERTATION

Trace-based Debugging and Visualization of Concurrent Java Programs with UML
Doctoral Thesis. Faculty of Electrical Engineering, Computer Science and Mathematics, University of Paderborn, Februar 2005.
Dissertation (English). Abstract (English). Zusammenfassung (deutsch).
I did my PhD Thesis on debugging of multi-threaded Java programs and supervised a bachelor and a diploma thesis. I built a prototype that generates traces, visualizes them in UML, and automatically detects liveness failures and their potentials. The prototype uses the Java Platform Debugger Architecture (JPDI) API of the Java Virtual Machine (JVM). The failure classification is based on the IEEE definition of Std 610.12 for error, mistake, fault and failure. Java is prone to the following failures:
- synchronization deadlock
- wait-induced deadlock
- missed notification
- nested monitor lockout
- circular join
- self join
- join-induced deadlock
