  • Construction and Civil Infrastructures Monitoring Systems

    Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...

  • Algorithmic network monitoring for a modern water utility: a case study in Jerusalem

    We report on the design, deployment, and use of TaKaDu, a real-time algorithmic Water Infrastructure Monitoring solution, with a strong focus on water loss reduction and control. TaKaDu is provided as a commercial service to several customers worldwide. It has been in use at HaGihon, the Jerusalem utility, since mid 2009. Water utilities collect considerable real-time data from their networks, ...

  • Design of a biomimetic-based monitoring and diagnostic system for civil structures

    Recent high intensity natural events such as hurricanes, tsunamis, and earthquakes have introduced new challenges for the design, maintenance, and sustainability of civil structures. Globally, civil infrastructures are deteriorating at an alarming rate caused by overuse, overloading, aging, damage or failure due to natural or man-made hazards. With such a vast network of deteriorating ...

  • A smart decision support systems based on a fast classifier and a semantic post reasoner

    In modern monitoring systems for critical infrastructures protection, there is the need to design automatic decision support systems with high reliability and real-time constraints. These features are usually in contrast as there is a significant trade-off between performance and precision. In this paper, we propose an innovative approach for smart event detection and enriched phenomena ...

  • SeNsiM-SEC: secure sensor networks integration to monitor rail freight transport

    In recent years, the interest in monitoring infrastructures has spread in many application domains, even because of the number of natural disasters and terrorist attacks. This important activity can be seen in the general context of critical infrastructure protection, such as the freight trains meant for hazardous materials transportation. The design of these systems must answer to several ...

  • Central African Republic`s infrastructure : a continental perspective

    Between 2000 and 2005 infrastructure made a modest net contribution of less than one percentage point to the improved per capita growth performance of the Central African Republic (CAR), despite high expenses in the road sector. Raising the country's infrastructure endowment to that of the region's middle-income countries could boost annual growth by about 3.5 percentage points. Assuming that the ...

  • How to measure the degree of interdependencies among critical infrastructures

    In the last years, the problem of analysing the interdependencies existing among critical infrastructures (CI) has assumed a great importance. Some attempts have been done to characterise, qualify and quantify these phenomena. Unfortunately, the largest part of these studies is devoted to model interdependencies and to emphasise the causes. Conversely, very few works are devoted to define ...

  • Municipal water demand and efficiency analysis: Case studies in Turkey

    The growing demand for municipal water due to population increase and urbanization impels water managers to reconsider the existing traditional supply-sided management approach. Strengthening of water demand management (WDM) policies by improving water use efficiency has been adopted as a key target in arid regions, in particular. Indeed, increasing the added value per m3 of water used is gaining ...

  • Implementation of an on-line artificial intelligence district meter area flow meter data analysis system for abnormality detection: a case study

    Faster detection of bursts saves water, minimises the inconvenience of interruption to customers and decreases the damaging consequences to infrastructure. Flow monitoring techniques are used by water service providers to monitor leakage, generally through offline application of mass balance type calculations and manual observations of change in night line values. This paper presents the ...

  • Using the Gini index to measure the inequality in infrastructure services provided within an urban region

    In this article, we suggest the use of the Gini index to measure the inequality in infrastructure services provided within an urban region. We develop a functional form for the Lorenz curve, the basis of measurement of the Gini index. The sparse nature of data available to measure the distribution of infrastructure services within an urban region makes estimating the Lorenz curve challenging. ...

  • Discussion on the Gaussian assumption in flow rate measurements using a primary weighing method

    Flow rate measurement is a common task in many hydraulic infrastructures included in systems with a large impact on the economy. The quality requirements that such measurement must fulfil imply the best knowledge of the measurement results (estimates and measurement uncertainties). Methods such as those given by the Guide for the Expression of Uncertainty in Measurement (GUM) have been widely ...

  • Precipitation measurement in high mountains - Aosta Valley - Case study

    Precipitation monitoring in remote areas without infrastructure was thought to be impossible in Aosta Valley, Italy. All the more challenging was the task to install a measuring site on the Peak CIMO Blanche with its height of 3000 meters (just shy of 10,000 feet), located near the famous Matterhorn.  The measuring site needed to withstand the extreme weather conditions that comes with ...
