Quantifying vulnerability to critical infrastructure has not been adequately addressed in the literature. Thus, the purpose of this article is to present a model that quantifies vulnerability. Vulnerability is defined as a measure of system susceptibility to threat scenarios. This article asserts that vulnerability is a condition of the system and it can be quantified using the Infrastructure V...

OBJECTIVE To describe OH&S vulnerability across a diverse sample of Canadian workers. METHODS A survey was administered to 1,835 workers employed more than 15 hrs/week in workplaces with at least five employees. Adjusted logistic models were fitted for three specific and one overall measure of workplace vulnerability developed based on hazard exposure and access to protective OH&S policies an...

introduction because of expansion of agricultural activities and excessive use of chemical fertilizers and location of municipal and industrial wastewater of andimeshk, it is possible for this aquifer to be polluted. therefore, the aim of present study is to assess the aquifer vulnerability of andimeshk plain and recognition of sensitive areas against pollution which this work can be conducted ...

BACKGROUND The evidence that heat waves can result in both increased deaths and illness is substantial, and concern over this issue is rising because of climate change. Adverse health impacts from heat waves can be avoided, and epidemiologic studies have identified specific population and community characteristics that mark vulnerability to heat waves. OBJECTIVES We situated vulnerability to ...

The economy of China and the travel needs of its citizens depend significantly on the continuous and reliable services provided by its railway system. However, this system is subject to frequent natural hazards, such as floods, earthquakes, and debris flow. A mechanism to assess the railway system vulnerability under these hazards and the design of effective vulnerability mitigation strategies ...

With increasing faults and attacks on the Internet infrastructure, there is an urgent need to develop techniques to analyze network and service vulnerability under organized fault attacks. Network vulnerability refers to the impact of attacks and faults on network and system behaviors. An accurate vulnerability analysis requires a deep understanding of failure modes and effects on each of the n...

The seismic vulnerability of an urban area is of a great deal for local authorities especially those facing earthquakes. So, it is important to have an efficient tool to assess the vulnerability of existing buildings. The use of the VIP (Vulnerability Index Program) and the GIS (Geographic Information System) let us to identify the most vulnerable districts of an urban area. The use of the vuln...

The security of information systems has been the focus because of network applications. Vulnerability analysis is widely used to evaluate the security of a system to assure system security. With the help of vulnerability analysis, the security risk of a system can be predicted so that the countermeasures are arranged in advance. These will promote system security effectively. The object of vuln...
