We introduce CoCasl as a light-weight but expressive coalgebraic extension of the algebraic specification language Casl. CoCasl allows the nested combination of algebraic datatype...
Control-flow analysis of business process models requires to check the absence of lack of synchronization. We use workflow graphs, which may contain inclusive OR gateways, to repre...
Models for visualization are important, helping the developer and user to understand the visualization process; to follow the connections and the data paths through the system; an...
Higher-order pushdown systems (PDSs) generalise pushdown systems through the use of higher-order stacks, that is, a nested “stack of stacks” structure. These systems may be us...
There have been significant advances on formal methods to verify complex systems recently. Nevertheless, these methods have not yet been accepted as a realistic alternative to the ...
