Effective manipulation of string data is of fundamental importance to modern database applications. Very often, textual inconsistencies render equality comparisons meaningless and strings have to be matched in terms of their similarity. Previous work has proposed techniques to express similarity operations using declarative SQL statements. However, the non-trivial issue of embedding similarity ...

Is it possible that the lengths of two sides of a primitive Heron triangle have a c ommon factor? The triangle with sides 9, 65, 70 and area 252 shows that this is possible. But notice that the common factor 5 is a prime of the form 4+1. Surprisingly, however, such a common factor cannot be a prime of the form 4 ; 1. Heron's name is familiar to anyone who has used the formula = p s(s ; a)(s ; b...

This paper presents a set of guidelines to help software engineers with the specification and design of large-scale semantic applications by defining new processes for Requirements Engineering and Design for semantic applications. To facilitate its use to software engineers not experts in semantic technologies, several techniques are provided, namely, a characterization of large-scale semantic ...

At any given step in the architectural design process, a designer can usually only consider a small subset of the actions that can be applied to a design along with the consequences of those actions on the overall design process. Computer-based design tools can enable humans to operate more efficiently in this process. In the end, the design product (i.e., a built environment) is meant to be us...

In a recent R&D project, our research group developed an industrial AGV transportation system using a multiagent system (MAS). The software architecture of this system is modeled using several architectural views. In this paper, we study an alternative way of structuring of the architectural description using Theme/UML. Theme/UML is an aspect-oriented design approach that provides support for a...
