Identifying potential vulnerable code is important to improve the security of our software systems. However, manual detection vulnerabilities requires expert knowledge and time-consuming, must be supported by automated techniques. Such vulnerability techniques should achieve a high accuracy, point developers directly fragments, scale real-world software, generalize across boundaries specific pr...

The increased availability and accuracy of multi-sources data enhance the simulation quality of natural disasters (hazard). Moreover, it enables a better prediction of their impact on the territory (vulnerability). Numerical representation of relief (DTM) is a prime necessity in risk simulation, in particular in flood study. Integrating 2D objects into a DTM significantly improves the relief re...

Floods are one of the most common and widely distributed natural risks to life and property. There is a need to identify the risk in flood-prone areas to support decisions for risk management, from high-level planning proposals to detailed design. There are many methods available to undertake such studies. The most accepted, and therefore commonly used, of which is computer-based inundation map...

This paper presents a framework to integrate several sources of spatial information to derive a map of seismic vulnerability for the city of Arica, Chile, which has been historically affected by this natural hazard. The proposed method is based on generating a geographical database with different variables that are related to human activity, considering factors of potential reduction and increa...

The degraded ecosystem in the Loess Plateau region of China is very vulnerable, which has a great impact on regional sustainable development. Taking the Loess Plateau of Yan’an, Shaanxi province, China, as the study area, this study quantitatively evaluated conditions of the ecological environment. Based on natural factors, environmental factors, and socio-economic factors of Yan’an in 1997, 20...

Climate change, although a natural phenomenon, is accelerated by human activities. Disaster policy response to climate change is dependent on a number of factors, such as readiness to accept the reality of climate change, institutions and capacity, as well as willingness to embed climate change risk assessment and management in development strategies. These conditions do not yet exist universal...

Natural and man-made hazards may affect industrial production sites by both direct losses (due to physical damage to assets and buildings) and indirect losses (production losses). Indirect losses, e.g. from production downtimes, can exceed direct losses multiple times. Thus, the vulnerability of industrial sectors to indirect losses is an important component of risk and its determination is an ...

This paper presents a model of factors influencing levels of human losses from natural hazards at the global scale, for the period 1980–2000. This model was designed for the United Nations Development Programme as a building stone of the Disaster Risk Index (DRI), which aims at monitoring the evolution of risk. Assessing what countries are most at risk requires considering various types of haza...

1. introduction nowadays, population increase, progress in science and technology and development of industrial installations with the shortage of places in metropolitan areas have made considerable changes in the morphology of watersheds. violation to territory of rivers, channels, and streams causes alterations in natural drainage pattern and overflowing due to the lower capacity of the chang...
