In case of underspecified or not fully predictable systems, models specifying system
behaviors are nondeterministic. Nondeterminism poses several challenges for the validation …

Modern software is increasingly concurrent, timed, distributed, and therefore, non-
deterministic. While it is well known that tests can be generated as LTL or CTL model …

Abstract Information sources over the WWW contain a large amount of data organized
according to different interests and values. Thus, it is important that facilities are there to …

The driving force in object-oriented analysis to use the concept of specialization/
generalization is polymorphism: the capability and need to reason about the union of the …

In runtime verification, operational models describing the expected system behavior offer
some advantages with respect to declarative specifications of properties, especially when …

This paper describes a semi-automatic transformation from object-oriented conceptual
models to logical theories. By associating a logical theory with a conceptual model, we are …

A major purpose of analysis is to represent precisely all relevant facts, as they are observed
in the external world. A substantial problem in object-oriented analysis is that most …

State-based transition systems can take advantage of a symbolic representation of the
concepts of state and transition in order to automatically solve verification questions that …

The major goal of analysis is to establish the functional requirements of the system to be
developed and to establish the real-world facts that are involved in these requirements …

QBF formulae are usually considered in prenex form, ie the quantifier block is completely
separated from the propositional part of the QBF. Among others, the semantics of the QBF is …
