conclusions there was a significant correlation between elevated lipase levels and the incidence of multiple organ failure. moreover, no significant association was found between the elevated amylase levels and organ failure. however, on admission, measurement of these enzymes coupled with routine laboratory investigations can be a powerful tool in the early detection of patients progressing to...

EEective detection of failures is essential for reliable communication services. Traditionally , non-real-time computer networks have relied on behavior-based techniques for detecting communication failures. That is, each node uses heartbeats to detect the failure of its neighbors , and the end-to-end transport protocol (e.g., TCP) achieves reliable communication by acknowledgment/retransmissio...

Car failure detection is a complicated process and requires high level of expertise. Any attempt of developing an expert system dealing with car failure detection has to overcome various difficulties. This paper describes a proposed knowledge-based system for car failure detection. The paper explains the need for an expert system and the some issues on developing knowledge-based systems, the ca...

One of the fundamental differences between a centralized system and a distributed one is the notion of partial failures. The ability to efficiently and accurately detect failures is a key element underlying reliable distributed computing. In current distributed systems however, failure detection is either left to the application developer or hidden from the programmer and provided in an ad hoc ...

This paper discusses preliminary investigations on the behaviour of the error handling mechanisms in Erlang, a parallel language which is renowned for its fault tolerant capabilities. A formal model is defined in order to provide a precise and unambiguous description of the behaviour of these mechanisms. The correctness of the model is evaluated by considering a simple Erlang program and compar...

It is widely recognized that distributed systems would greatly benefit from the availability of a generic failure detection service. Such a service can however prove useful only if it can adapt simultaneously to changing network conditions and conflicting application requirements. This paper presents a novel approach to adaptive failure detectors, called φ-failure detectors, which dynamically a...
