In this paper we discuss the benefits of extending VRML by constraints and present a new way based on prototypes and scripting to implement this extension. Our approach is easy-t...
Discrete event dynamic systems may have extremely large state spaces. For their analysis, it is usual to relax the description by removing the integrality constraints. Applying thi...
In this paper we propose a visual interface for the specification of predicates to be used in queries on spatio-temporal databases. The approach is based on a visual specification...
Accessing and integrating data from heterogeneous sources has become a significant challenge. So-called adapters provide the functionality for translating SQL queries into querie...
With the recent advent of deep sub-micron technology and new packaging schemes such as Multi-Chip Modules(MCMs), integrated circuit components are often not rectangular. Most exis...
