Towards an operational database for real-time environmental monitoring and early warning systems

Operational real - time GPS - enhanced earthquake early warning

Moment magnitudes for large earthquakes (Mw ≥7.0) derived in real time from near-field seismic data can be underestimated due to instrument limitations, ground tilting, and saturation of frequency/amplitude-magnitude relationships. Real-time high-rate GPS resolves the buildup of static surface displacements with the S wave arrival (assuming nonsupershear rupture), thus enabling the estimation o...

Towards Runtime Monitoring in Real-Time Systems

In this paper we present the state of our work on runtime monitoring for real-time systems: a way to observe system behavior online without unpredictably disturbing real-time properties. We discuss generic requirements to achieve these properties wherefrom we deduce our monitoring framework architecture. We describe this architecture in detail and discuss several challenges for our implementati...

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...
