1. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases
Abstract : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. READ MORE

2. Management of Real-Time Data Consistency and Transient Overloads in Embedded Systems
Abstract : This thesis addresses the issues of data management in embedded systems' software. The complexity of developing and maintaining software has increased over the years due to increased availability of resources, e.g., more powerful CPUs and larger memories, as more functionality can be accommodated using these resources.

3. Virtual Full Replication for Scalable Distributed Real-Time Databases
Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

4. Performance Aspects of Databases and Virtualized Real-time Applications
Abstract : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.

5. Maintaining data consistency in embedded databases for vehicular systems
Abstract : The amount of data handled by real-time and embedded applications is increasing. This calls for data-centric approaches when designing embedded systems, where data and its metainformation (e.g., temporal correctness requirements) are stored centrally. READ MORE
