Modeling systems based on semi-formal graphical formalisms, such as Statecharts, has become standard practice in the design of reactive embedded devices. However, the modeling of ...
During the last decade, multidimensional databases have become common in the business and scientific worlds. Analysis places significant demands on the interfaces to these databas...
Graphical password systems based on the recognition of photographs are candidates to alleviate current over-reliance on alphanumeric passwords and PINs. However, despite being bas...
With the spread of the Internet and software evolution in complex intensive systems, software architecture often need be reconfigured during runtime to adapt variable environments...
: We concentrate on two major aspects of reactive system design: behavior control and modularity. These are studied from a formal point of view, within the framework of action syst...
