Modern distributed cyber-physical systems encounter a large variety of anomalies and in many cases, they are vulnerable to catastrophic fault propagation scenarios due to strong connectivity among the sub-systems. In this regard, root-cause analysis becomes highly intractable due to complex fault propagation mechanisms in combination with diverse operating modes. This paper presents a new data-...

The face stability of shallow tunnels was investigated with small-scale model experiments at single gravity. Aim of the research was to detect the evolution of failure mechanisms in dense and loose soil samples with varying overburden above the tunnel. Moreover, the quality of proposed theoretical/numerical approaches for the determination of a necessary support pressure pf was assessed. The re...

Funding information TUBITAK TEYDEB 1501, Grant/Award Number: 3130411 Summary Mobile network operators run Operations Support Systems that produce vast amounts of alarm events. These events can have different significance levels and domains and also can trigger other ones. Network operators face the challenge to identify the significance and root causes of these system problems in real time and ...

The MTS4000 MPEG Test System provides comprehensive MPEG transport streams analysis and interoperability testing. Its deep analysis of the transport streams, PES, and elementary streams helps track down sources of picture anomalies and identify transport streams with syntax errors. Its ability to capture events for deep analysis is also critical to identifying the root cause of problems. The op...
