    Terzis, Sotirios; Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1999-02)
    [Executive Summary] This document explores the issues in building the ?groupware of the future?. The approach is twofold. First we briefly describe our vision of a ?virtual enterprise? that is made up of a set of services ...
  • An Improved Translation of SA/RT Specification Model to High-Level Timed Petri Nets 

    Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1995-10)
    Structured analysis methods for real-time systems (SA/RT) are widely accepted by the industrial world as a mature approach to real-time systems design. These methods use highly expressive graphical specification languages ...
  • JFS: A Secure Distributed File System for Network Computers 

    O'Connell, Marcus; Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1999-03)

  • A Methodology for the Automated Introduction of Design Patterns 

    O Cinneide, Mel; Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1999-03)
    In reengineering legacy code it is frequently useful to introduce a design pattern in order to add clarity to the system and thus facilitate further program evolution. We show that this type of transformation can be ...
  • Objects, Components and the Virtual Enterprise 

    Nixon, Patrick; Dobson, Simon (Trinity College Dublin, Department of Computer Science, 1999-02)
    We are currently witnessing a convergence of several threads of technology and business imperatives. The idea of a virtual enterprise (VE) ? a business built from both organizationally and geographically distributed units ...
  • Program Restructuring to Introduce Design Patterns 

    O Cinneide, Mel; Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1999-02)
    In restructuring legacy code it may be useful to introduce a design pattern in order to add clarity to the system and thus facilitate further program evolution. We show that aspects of this transformation can be automated ...
