Due to abuse by insiders or penetration by outsiders, network systems usually suffer various security issues. In order to achieve high dependable and low cost monitoring, this paper proposes a dependable monitoring mechanism combining static threshold-based and dynamic anomaly detection. Firstly, the performance metrics of host and network are collected through different methods. In static thre...

This paper describes the development of a monitoring and assertion checking tool, MAC, which supports monitoring of symbolic execution traces generated by the Modechart Toolset, permitting testing of speciica-tions early in the design phase and providing a mechanism for evaluating properties of the system on a particular execution trace. This approach avoids the many of the diiculties of run-ti...

OSNR monitoring is indispensable for coherent systems to ensure robust, reliable network operation and potentially enable impairment-aware routing for future dynamic optical networks. In a long-haul transmission link with chromatic dispersion (CD) and fiber nonlinearity, it is difficult to distinguish between amplifier noise and fiber nonlinearity induced distortions from received signal distri...

aim and background: cognitivists have recently paid extensive attention to source monitoring deficit as an impairment in schizophrenic patients and is used in clarification of major symptoms including hallucination and delusion. therefore, the present study aimed to explore the effects of source monitoring ability in auditory hallucination. methods and materials: this causal-comparative study u...

abstract background: intensive care unit is a center to provide comprehensive care for critically ill patients whose condition can be improved by receiving specialized care. the importance of accurate and rapid monitoring of patients at this precise moment is in recording patient data and its comparison with previous data. monitoring the patient by either devices or direct examination of the nu...

Two critical problems exist in traffic monitoring and analysis of today's Internet traffic compared to the past network environment. The first is how to capture and handle the huge amount of traffic data in a real-time manner generated from high-speed network links, such as 2.5 Gbps and higher. The second is how to analyze diverse and complex types of traffic generated by many different types o...
