The analysis of flow in water-distribution networks with several pumps by the Content Model may be turned into a non-convex optimization uncertain problem with multiple solutions. Newton-based methods such as GGA are not able to capture a global optimum in these situations. On the other hand, evolutionary methods designed to use the population of individuals may find a global solution even for ...

Maintaining water quality in distribution systems has become a prominent issue in the study of water networks. This thesis concentrates on disinfectant and particle counts as two important indicators of water quality. The models discussed in this work are based on data collected by the author. The experimental set-up and procedure are described and observations of particle counts, particle coun...

This work contributes a modeling framework to characterize the effect of cyber-physical attacks (CPAs) on the hydraulic behavior of water distribution systems. The framework consists of an attack model and a MATLAB toolbox named epanetCPA. The former identifies the components of the cyber infrastructure (e.g., sensors or programmable logic controllers) that are potentially vulnerable to attacks...

Measuring the performance of infrastructure networks is critical to allocation resources before, during, and after a system’s disruption. However, lack data often hinders ability accurately estimate performance, resulting in uncertainty its evaluation which can lead biased estimates. To address this challenge, study develops Bayesian approach measure network at component level incorporate it sy...

Telemedicine is the use of telecommunication and information technologies in order to provide clinical health care at a distance. These technologies allow communications between patient and medical staff with convenience as well as the transmission of medical, imaging and health informatics data from one site to another. It is also used to save lives in critical care and emergency situations. A...

Canadian municipalities spend $12 to $15 billion annually on infrastructure but it never seems to be enough. Moreover, some municipal water systems in Canada were installed over 100 years ago. The challenge of funding infrastructure renewal is not really a financial challenge so much as it is a planning challenge. The developed funding renewal plan considers several factors and their effect on ...

Article history: Received 27 April 2012 Received in revised form 13 September 2013 Accepted 9 February 2014 Available online 11 March 2014 This paper seeks to uncover and examine the complex set of governance challenges associated with transforming energy distribution networks, which play a key enabling role in a low carbon energy transition. We argue that, although the importance of such infra...
