African economies, through Agenda 2063, recognize that developing infrastructure – transport, electricity, energy, water, and e-connectivity will be critical for the region to assume a lasting place in global economic system. As result, this paper addresses continent’s gap provides an important insight into rapidly growing presence of China’s official financing Africa as well distinctive charac...

Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...

The present debate concerning the National Information Infrastructure (NII)[1] has focused primarily on the introduction of competitive markets for the supply and distribution of information. Although competition will be an important component of the NII, and one which we welcome, we argue that it is inappropriate to frame the debate entirely in terms of competition. Competition can be seen as ...

This paper is offered as a contribution to the Workshop on Cross-learning between Spatial Data Infrastructures, and Information Infrastructures, Enschede, 31 March-1 April, 2005. Its purpose is to consider some of the key challenges we see for the development of Spatial Data Infrastructures (SDIs) in the short and medium term. Although much attention has been given recently to the initiative of...

Our objective is to design a metric that can be used to measure the size of projects that install and configure COTS stand-alone software, firmware and hardware components. We call these IT infrastructure, as these components often form the foundation of the information system that is built on top of it. At the moment no accepted size metric exists for the installation and configuration of stan...

Building for a sustainable environment requires sustainable infrastructure assets. Infrastructure capacity management is the process of ensuring optimal provision of such infrastructure assets. Effectiveness in this process will enable the infrastructure asset owners and its stakeholders to receive full value on their investment. Business research has shown that an organisation can only achieve...
