This paper considers the generation of some interpretable fuzzy rules for assigning an amino acid sequence into the appropriate protein superfamily. Since the main objective of this classifier is the interpretability of rules, we have used the distribution of amino acids in the sequences of proteins as features. These features are the occurrence probabilities of six exchange groups in the seque...

I introduce a way of verifying phonological processes on the basis of phonetic substances obtained by automatic speech recognition. The acoustic characteristics of phone-like units are modelled using automatic speech recognition techniques. This phone recogniser is run on the data tokens whose segmental structure matches with the context of target processes to be verified. Examining output stri...

With the success of model-driven development as well as component-based and service-oriented systems, models of software architecture are key artefacts in the development process. To adapt to changing requirements and improve internal software quality such models have to evolve while preserving aspects of their behaviour. To avoid the costly verification of refactoring steps on large systems we...

Network security is a branch of network management in which network intrusion detection systems provide attack detection features by monitorization of traffic data. Rule-based misuse detection systems use a set of rules or signatures to detect attacks that exploit a particular vulnerability. These rules have to be handcoded by experts to properly identify vulnerabilities, which results in misus...

This thesis presents the first formalization of the Owicki-Gries method and its compositional version, the rely-guarantee method, in a theorem prover. These methods are widely used for correctness proofs of parallel imperative programs with shared variables. We define syntax, semantics and proof rules in Isabelle/HOL, which is the instantiation of higher-order logic in the theorem prover Isabel...

Event-condition-action (ECA) rules specify a decision making process and are widely used in reactive systems and active database systems. Applying formal verification techniques to guarantee properties of the designed ECA rules is essential to help the error-prone procedure of collecting and translating expert knowledge. The nondeterministic and concurrent semantics of ECA rule execution enhanc...
