This article seeks to highlight the importance of Vulnerability in reducing damage caused by Natural Disasters.The concept of Vulnerability has been approached by researchers who dedicate themselves to this theme mainly in the twentieth century.In egg shaker this way, it is intended to address the conceptual development on disasters, hazard and vul
Hexagonal discrete global Downstem grid systems are the preferred data models supporting multisource geospatial information fusion.Related research has aroused widespread concern in the academic community, and hierarchical indexing algorithms are one of the main research focuses.In this paper, we propose an algorithm for indexing the cell of a ring
An experimental study of ignition risk due to hot points in the storage of bulk materials is required to ensure fire safety.Many parameters are involved in this Saffron phenomenon: nature of the material, storage volume and temperature, type and size of hot point, etc.The aim of this study is to determine critical ignition temperatures of hot spots
In large-scale high-speed rail networks (HSRNs), the occurrence of occasional malfunctions or accidents is unavoidable.The key issue considered in this study is the optimal allocation of the maintenance costs, based on the stochastic risk assessment for HSRNs.Inspired by Mop Racks the theoretical risk evaluation methods in the complex network, thre
