Revisiting the notion of function

Functions play a central role in type theory, logic and computation. We describe how the notions of functionalisation (the way in which functions can be constructed) and instantiation (the process of applying a function to an argument) have been developed in the last century. We explain how both processes were implemented in Frege’s Begriffschrift, Russell’s Ramified Type Theory, and the λ-calc...

The Notion of Active Object - Oriented

Open Hypermedia Systems (OHS) are characterized by distributed, heterogeneous pieces of information. To cope with the main challenges of OHS one has to tackle consistency, eeciency, and interoperability issues. In this position paper we propose an OHS architecture based on an active object-oriented database system as well as SGML/HyTime as standardized interchange formats. By using active objec...

On the Notion of Value Object

It is increasingly recognized that business models offer an abstraction that is useful not only in the exploration of new business networks but also for the design and redesign of operational business processes. Among others, they can be used as input for a risk analysis that is crucial in cross-organizational business process design. However, the notion of value object is up till now not clear...

Tolerance synthesis: quantifier notion and virtual boundary

The purpose of functional tolerancing process is to define the geometrical specifications of parts ensuring functional requirements. For automotive and aircraft industries, the tolerance synthesis has become an important issue in product design process. Indeed, designers need methods and rules to determine the tolerances. To define rules, a mathematical formulation of tolerance synthesis is det...
