There are many reasons for reverse engineering or reengineering legacy systems. To date, many approaches concerning re-engineering of legacy systems have been made. The majority of these approaches are dealing with systems in the field of business applications. This paper describes the work performed for the E-CARES project so far. This project is concerned with understanding and re-structuring...

Railway wireless communication has become an indispensable part to provide the reliability and safety of the railway operation as well as the improved railway services. In addition, advanced mobile communication technologies have triggered new railway customer services. Thanks to many benefits of the 4-generation mobile communication technology, long-term evolution (LTE), this technology is one...

We present a quantum teleportation experiment in the quantum relay configuration using the installed telecommunication network of Swisscom. In this experiment, the Bell-state measurement occurs well after the entanglement has been distributed, at a point where the photon upon which data are teleported is already far away, and the entangled qubits are photons created from a different crystal and...

This document describes ongoingwork to be performed on a research project during the period 16 September 2002 through 15 September 2003. In subsequent sections we provide background information for the project taken from the research proposal and present some ideas that were sent recently in a progress report to the providers of the research funds. The goals of this research project are: (1) to...

Teletraffic phenomenon in classical and new telecommunication networks can be more systematically described and different system-type problems can be effectively solved using fundamental concepts of systems and GSPS (General Systems Problem Solver) methodology. Basic presupposition is that general systems methodology is usable as a logicomathematical methodology in formulation, derivation and e...
