Towards a typology of integrated functional early warning systems

Lack of common measures in evaluating, comparing and contrasting Early Warning Systems (EWSs) is a persistent problem. As such, there is a growing need for an abstract technical definition of EWSs and a framework to classify them, which would help developers set standards. The standards can be the basis for effective EWS deployments. Practitioners and researchers have been using EWSs for ...

Decision support system for predicting tsunami characteristics along coastline areas based on database modelling development

Tsunamis are extraordinary occurrences that are difficult to identify; most of the incidents have no recorded predictions and tsunamis are generally infrequent events with poor data acquisition. The development of a tsunami database system has become important for improving the management of information with regard to a tsunami early warning system for vulnerable communities along coastline ...

Signal analysis and anomaly detection for flood early warning systems

We describe the detection methods and the results of anomalous conditions in dikes (earthen dams/levees) based on a simultaneous processing of several data streams originating from sensors installed in these dikes. Applied methods are especially valuable in cases where lack of information or computational resources prohibit computing the state of the dike with finite element and other ...

Simulation and anticipation of domino effects among critical infrastructures

Interdependencies among critical infrastructures (CIs) are the cause of domino effects that may have serious consequences for society. To limit the consequences of these phenomena, it is important to be able to anticipate any situation that may trigger a domino effect. To do so, it is necessary to have a good understanding of how CIs are interlinked and how they rely on each other to properly ...

A review of sensor placement objective metrics for contamination detection in water distribution networks

Security of water distribution networks (WDNs) through early warning systems is one of the topics of research over the last two decades to safeguard human health and the environment against accidental and intentional contamination. Several methodologies have been suggested by different researchers for placement of sensors in WDNs which can provide early warning. Owing to the cost of both ...

The SESAMO early warning system for rainfall-triggered landslides

The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that ...

Centinela: an early warning system for the water quality of the Cauca River

The Cauca River is the drinking water source for 1.3 million inhabitants of the city of Cali, Colombia. Although the river discharge is sufficient to handle the water demand of the city all year long, significant water pollution events cause frequent disruption to the Puerto Mallarino Treatment Plant (PMTP) and the water supply service, with substantial social and economic impacts on the city. ...

Predicting air quality in Uberlandia, Brazil, using linear models and Neural Networks

Particulate air pollution causes a wide range of effects on human health, including disorders of the respiratory and cardiovascular systems, asthma and can cause mortality. Hence, the development of an efficient air quality forecasting and early warning system is an obvious and imperative need. The objective of this work was to investigate this forecasting possibility using linear models (such as ...

Just a game? How continuous time modelling can ameliorate corporate strategy games

Strategy games are a popular part of today’s management training in education and business. Complex economic interrelationships can be illustrated and interdependencies of economic decisions can be more easily understood. Most business games work with a discrete time model, i.e., decisions are made once for an entire time period; usually one fiscal year. Possible drawbacks of the discrete time ...

Early warning system for home users and small- and medium-sized enterprises: eight lessons learned

This paper outlines how early alert systems can help home users and Small- and Medium-Sized Enterprises (SMEs) in improving their security hygiene (culture of security). The viability of our framework and concepts are evaluated using www.CASEScontact.org as a case study. The latter offers its services to targeted groups of home users and SMEs supporting them in better protecting their information ...

Inconsistency of food security information in Sudan

Agriculture is the backbone of economic and social development in Sudan, with 80% of the population depending on agriculture and all other sectors being largely dependent on it. Food security information is the key to food security and its timely availability, reliability and usability not only averts disaster, but also leads to developments that improve people's livelihoods (Mati, 2005). Food ...

Organic sum parameters for river monitoring

The purpose of river monitoring is to have an early warning system for chemical accidents with the consequence of water pollution through hazardous chemical substances. The real objective goes even further because the early warning system is intended for protecting the sensible drinking water resources. River monitoring stations have been established along rivers around the world. Today there is ...

Early warning of disasters: Facts and figures

Lucy Pearson looks at early warning systems for disasters, their uses and limits, and what accounts for the gap between warning and action. Through history disasters have destroyed lives and livelihoods, killing people and damaging homes and businesses. Disasters in the past 35 years have taken an estimated 2.5 million lives and cost more than US$1.5 billion, mainly in developing countries. [1] ...

Abrupt Impacts of Climate Change: Anticipating Surprises

Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with ...

Pathogen security: the illusion of security in foreign policy and biodefence

'Pathogen security' (sometimes called 'biosecurity') is too often seen as the primary strategy to combat bioterrorism. Asserting that materials, technologies and expertise for bioterrorism are available worldwide and that terrorist groups are increasingly able to obtain and disseminate infectious disease pathogens, advocates contend that pathogen security systems and practices are central to ...

Using disaster warning tools to their best potential

Stronger links between scientific tools and the environment in which they operate can improve the effectiveness of early warning. To say there is a lot riding on disaster management is an understatement. The lives and livelihoods lost, as well as extensive damage, underscore the human, environmental, social and economic cost of extreme events that affect millions every year. [1] Consider just a ...
