Designing Distributed Database Systems for Efficient Operation

Distributed database systems can yield significant cost and performance advantages over centralized systems for geographically distributed organizations. The efficiency of a distributed database depends primarily on the data allocation (data replication and placzment) and the operating strategies (where and how retrieval and update query processing operations are performed). We develop a distri...

An Authorization Framework for Database Systems

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...

O11: Safety Potential of Advanced Driver Assistance Systems

Advanced driver assistance systems (ADAS) have the potential to accomplish a major contribution to road safety. This is valid for minor crashes to very severe accidents with personal injuries. The Allianz Centre for Technology attends the development of new driver assistance systems by carrying out accident analysis and estimating the efficiency of new ADAS. In this context new ADAS from differ...

Direct Positioning with Channel Database Assistance

When we have knowledge of the positions of nearby walls and buildings, estimating the source location becomes a very efficient way of characterizing and estimating a radio channel. We consider localization performance with and without this knowledge. We treat the multipath channel as a set of ‘virtual receivers’ whose positions can be pre-stored in a channel database. Using wall knowledge, we d...
