With short production development times, there is an increased need to demonstrate product reliability relatively quickly with minimal testing. In such cases there may be few if any observed failures. Thus it may be difficult to assess reliability using the traditional reliability test plans that measure only time (or cycles) to failure. For many components, degradation measures will contain im...

IP multicast is the most often used technique to transport multimedia data over the internet. Due to the low resource requirements when transmitting one multimedia stream to more than just one client, it is deployed in most backbone networks as well as in most campus networks. Typical services are video broadcasts or video conferences. IP multicast like IP does not support to transport realtime...

This paper introduces a new probabilistic specification of reliable broadcast communication primitives, called Reliable Broadcast. This specification captures in a precise way the reliability of practical broadcast algorithms that, on the one hand, were devised with some form of reliability in mind but, on the other hand, are not considered reliable according to “traditional” reliability specif...

An approach is proposed for robust online behaviour recognition and abnormality detection based on discovering natural grouping of bebaviour patterns through unsupervised learning and a time accumulative reliability measure. A novel behaviour learning model and a run-time accumulative reliability measure are introduced to determine both the natural groupings of possible normal behaviour classes...

Information retrieval studies that involve searching the Internet or marking phrases usually lack a well-defined number of negative cases. This prevents the use of traditional interrater reliability metrics like the kappa statistic to assess the quality of expert-generated gold standards. Such studies often quantify system performance as precision, recall, and F-measure, or as agreement. It can...
