Given the intractability of exhaustively verifying software, the use of runtime-verification, to verify single execution paths at run-time, is becoming popular. Although the use of runtime verification is increasing in industrial settings, various challenges still are to be faced to enable it to spread further. We present dynamic communicating au-tomata(More)
To avoid large overheads induced by runtime monitoring, the use of asynchronous log-based monitoring is sometimes adopted — even though this implies that the system may proceed further despite having reached an anomalous state. Any actions performed by the system after the error occurring are undesirable , since for instance, an unchecked malicious user may(More)
With numerous specialised technologies available to industry, it has become increasingly frequent for computer systems to be composed of heterogeneous components built over, and using, different technologies and languages. While this enables developers to use the appropriate technologies for specific contexts, it becomes more challenging to ensure the(More)
The use of runtime verification, as a lightweight approach to guarantee properties of systems, has been increasingly employed on real-life software. In this paper, we present the tool LARVA, for the runtime verification of properties of Java programs, including real-time properties. Properties can be expressed in a number of notations, including(More)
Two new techniques for remote protein homology detection particulary suited for sparse data are introduced. These methods are based on position specific scoring matrices or profiles and use a support vector machine (SVM) for discrimination. The performance on standard benchmarks outperforms previous non-discriminative techniques and is comparable to that of(More)
