Experiences modelling and using object-oriented telecommunication service frameworks in SDL

This paper describes experiences in using SDL and its associated tools to create telecommunication services by producing and specialising object-oriented frameworks. The chosen approach recognises the need for the rapid creation of validated telecommunication services. It introduces two stages to service creation. Firstly a software expert produces a service framework, and secondly a telecommunications ‘business consultant' specialises the framework by means of graphical tools to rapidly produce services. Here the focus is given to the underlying technology required. In particular, the advantages and disadvantages of SDL and tools for this purpose are highlighted

Meet the New Boss : The New Judicial Center

A document entitled ‘Guidelines on Constitutional Litigation’ published in 1988 by the Reagan era Department of Justice is the springboard for Professor Tushnet\u27s discussion of the Supreme Court\u27s new center. The Guidelines urged Department of Justice litigators to foster a nearly exclusive reliance on original understanding in constitutional interpretation and to resort to legislative history only as a last resort. The Guidelines also advised Department of Justice litigators to seek substantive legal changes including more restrictive standing requirements, an end to the creation of unenumerated individual rights, greater constitutional protection of property rights, and greater limits on congressional power. The discussion begins by viewing the Guidelines\u27 characterization of Supreme Court jurisprudence as an indication of the Court\u27s old center. The discussion then examines the Court\u27s subsequent development to reach an understanding of the Court\u27s new center. Professor Tushnet finds that although the Court at times seemed to entertain some views espoused by the Guidelines, the present Court\u27s center is remarkably like the Court\u27s center in 1988. Original understanding remains only one method of constitutional interpretation -not even the most important one - and legislative history continues to play a role in statutory interpretation. Furthermore, changes in Court\u27s jurisprudence involving standing, unenumerated rights, and congressional power remain limited (though there appear to be greater constitutional protections of property rights). The only notable difference is that the present Court has developed doctrines that could swing constitutional interpretation toward the approach taken by the Guidelines should newly appointed Justices want to endorse that approach. But for now the current Court is much the same as before

Abstractions of Hamiltonian control systems

Given a control system and a desired property, an abstracted system is a reduced system that preserves the property of interest while ignoring modeling detail. In previous work, abstractions of linear and nonlinear control systems were considered while preserving reachability properties. In this paper, we consider the abstraction problem for Hamiltonian control systems, where, in addition to the property of interest we also preserve the Hamiltonian structure of the control system. We show how the Hamiltonian structure of control systems can be exploited to simplify the abstraction process. We then focus on local accessibility preserving abstractions, and provide conditions under which local accessibility properties of the abstracted Hamiltonian system are equivalent to the local accessibility properties of the original Hamiltonian control system
