In this article we describe recent work done in building a university-wide grid at the University of Cambridge based on the Condor middleware [1]. Once the issues of stakeholder concerns (e.g. security policies) and technical problems (e.g. firewalls and private IP addresses) have been taken into account, a solution based on two separate Condor environments was decided on. The first of these is...

The purpose of this study is to analyse the impact of changes in Australian private health insurance coverage as seen in NSW public and private hospital birth profies, and identify trends in obstetric outcomes from 1997-2001. NSW Midwives Data Collection unit record data is analysed for women who gave birth to a live singleton baby of term gestation (> or = 37 weeks) and cephalic presentation i...

Within CAWICOMS a configuration workbench for customisable products and services will be developed which will have the following advantages versus current commercially available configuration technology: It will automate over the Web the skills of salespersons by developing adaptation and personalisation technology for inclusion in Web based configurators. The interaction with the user will be ...

This paper examines the challenges and opportunities facing the agricultural biotechnology sector as it works to sustain innovations and further propagate its benefits into the new century. We survey the milestones of technological, legal, and economic precedence in this area and discuss institutional mechanisms for public and private partnership that can help agricultural biotechnology fulfill...

The term “private” in virtual private network is sometimes taken for granted, and people can be too distracted by the “virtual” and “network” to really consider what is meant by “private.” In this paper, we consider the issues and meanings of the term private, and look at these issues with respect to two of the dominant VPN technologies, IPsec and MPLS.

We propose different formulations as well as efficient solution approaches for the VPN design problem under traffic uncertainty with symmetric bandwidths.

Managing and utilizing storage resources have resulted in complexity because of the heterogeneous nature of storage infrastructures. Paper elucidates that Virtual Private Network created in the Wireless Public Network would have implemented virtualization and would result in enhancement of productivity and efficient management of storage infrastructures. Proof is generated that Virtual environm...

The paper describes an architecture allowing Mobile IP hosts to access to a virtual private network that is protected by a firewall from the public Internet. The implementation based on adaptation of standard protocols (IPSec and Mobile IP) and initial performance results are discussed.
