We consider positive rules in which the conclusion may contain existentially quantified variables, which makes reasoning tasks (such as Deduction) undecidable. These rules have t...
Design and validation of mixed-signal integrated systems require evel model abstractions. Generalized Volterra series based models have been successfully applied for analog and RF...
Abstract. We define a translation of aggregate programs to normal logic programs which preserves the set of partial stable models. We then define the classes of definite and str...
For self-organising emergent solutions, there is no support to explicitly design system-wide information flows and feedback loops in those flows. This is problematic because the...
Abstract. Use Cases are widely used for specifying systems, but their semantics are unclear in ways that make it difficult to apply use cases to complex problems. In this paper, we...
