Formal verification can be used to establish important properties of critical systems. However, applying formal methods to a low-level implementation of a complex system is a daunting challenge, in part because extracting abstract functionality from a specific implementation is tedious. Automating such efforts by placing them under computer control helps free the user to focus on the essence of...

The formal methods community has long known about the need to formally analyze concurrent software, but the OS community has been slow to adopt such methods. The foremost reasons for this are the cultural and knowledge gaps between formalists and OS hackers, fostered by three beliefs: inaccessibility of the tools, the disabling gap between the validated model and actual implementation, and the ...

The complexity of discrete systems developments process shows, that it is not realistic to expect, that the only universal formal method will exist, which will cover well all the aspects of this process. We are working towards formal methods integration in order to obtain deeper understanding of system under development/analysis. We chose Petri nets and process algebra, notations with complemen...

We describe BON-CASE, an extensible tool for the BON modelling language. The tool’s support for formal techniques – in particular, for formal specification of contracts and frames, as a platform for verification of Eiffel code, for lightweight integration with existing reasoning tools (such as type checkers, theorem provers, and static assertion checkers), and its extensible architecture – is d...

Formal Concept Analysis is a prominent field of applied mathematics handling collections of knowledge formal concepts which are derived from some basic data types, called formal contexts by using concept forming operators. One of the strengths of FCA is the elegant, intuitive and powerful graphical representation of landscapes of knowledge as concept lattices. Nevertheless, in case of triadic F...

This paper discusses the use of formal methods in testing of concurrent systems. It is argued that formal methods and testing can be mutually profitable and useful. A framework for testing based on formal specifications is presented. This framework is elaborated for labelled transition systems, providing formal definitions of conformance, test execution and test derivation. A test derivation al...

1. revised and extended axiomatic theory and proof development. 2. a new curriculum with extensive questions, intuitive illustrations of key concepts, exercises in formal proofs, and an emphasis on the use of mathematical logic as a formal tool for the analysis of informal concept". 3. parallel languages-a completely new formal language containing concise formulas for use in proofs together wit...

OnTrack automates workflows for railway verification, starting with graphical scheme plans and finishing with automatically generated formal models set up for verification. OnTrack is grounded on an established domain specification language (DSL) and is generic in the formal specification language used. Using a DSL allows the formulation of abstractions that work for verification in several for...

Inasmuch as formal methods have continued to gain popularity within the industrial community, they are still far from attaining widespread acceptance, especially within the information systems domain. Reasons range from lack of appropriate education and training to lack of tools that provide continuity by integrating formal techniques with more traditional methods that may be more familiar for ...

Background;Despite advances in technology, people are still exposed to fire hazard. Students can be one of the most important exposed groups. Therefore, fire safety inspection should be established in dormitories. The aim of this study was to develop a fire safety checklist for fire safety inspection in dormitories. Methods; This study was as a tool development followed by a cross-sectional st...
