Diagrams (e.g., trees for hierarchical structures, or graphs for finite state machines) are often needed as part of advanced user interfaces, and are frequently specific to a user’s application. The implementation of editors for diagrams should be supported by a tool and based on a formal model. This paper gives an overview of DiaGen, our generator for diagram editors. An editor for a certain k...

BioModel Analyzer (bma) is a tool for modeling and analyzing biological networks. Designed with a lightweight graphical user interface, the tool facilitates usage for biologists with no previous knowledge in programming or formal methods. The current implementation analyzes systems to establish stabilization. The results of the analysis— whether they be proofs or counterexamples—are represented...

In E-commerce processes, various rules and constraints regarding product specifications, pricing, terms and conditions are exchanged between vendors and buyers. Developing a formal model for those rules and constraints gives a foundation for new E-commerce applications. Our approach is to develop a constraint database holding these conditions as dynamic constraints and provide a query language,...

Component adaptation is widely recognised to be one of the crucial problems in ComponentBased Software Engineering. We present a formal methodology for adapting components with mismatching interaction behaviour. The four main ingredients of the methodology are: (1) The inclusion of behaviour specifications in component interfaces, (2) a simple, high-level notation for expressing adaptor specifi...

Diagrams (e.g., flowcharts, trees for hierarchical structures, or graphs for finite state machines) are often needed as part of visual language systems and advanced user interfaces, and are frequently application specific. The implementation of editors for diagrams should be supported by a tool and based on a formal model. This paper gives an overview of DiaGen, our generator for diagram editor...

The authors conducted an informal survey of contractors, customers, and certification authorities in the United States aerospace domain to identify barriers to the adoption of formal methods and suggested mitigations for those barriers. We surveyed 31 individuals from the following nine organizations: United States Army, Boeing, FAA, Galois, Honeywell, Lockheed Martin, NASA, Rockwell Collins, a...

The paper discusses how a bridge between the design practice and the formal methods could be maintained. The use of model checking seems to be the most promising approach. Then, the software environment COSMA is presented, implementated in the Institute of Computer Science,WUT. The conceptual framework of COSMA is based upon Concurrent State Machines (CSM) and Extended CSM, which are also brief...

This paper proposes a mortar finite element method for solving the two-dimensional second-order elliptic problem with jumps in coefficients across the interface between two subregions. Non-matching finite element grids are allowed on the interface, so independent triangulations can be used in different subregions. Explicitly realizable mortar conditions are introduced to couple the individual d...

The paper presents a tool-supported approach to graphically editing scheme plans and their safety verification. The graphical tool is based on a Domain Specific Language which is used as the basis for transformation to a CSP‖B formal model of a scheme plan. The models produced utilise a variety of abstraction techniques that make the analysis of large scale plans feasible. The techniques are ap...
