Fault tree analysis of large-scale blackout accidents

Designing Networks for Large-Scale Blackout Circumvention

Large-scale communications blackouts, such as those carried out by Egypt and Libya in 2011 and Syria in 2012 and 2013, have motivated a series of projects that aim to enable citizens to communicate even in the face of such heavy-handed censorship efforts. A common theme across these proposals has been the use of wireless mesh networks. We argue that such networks are poorly equipped to serve as...

Fault Propagation Analysis of Large-scale, Networked Embedded Systems

Public transport risk assessment through fault tree analysis

This study focused on the public transport risk assessment in District one of ​​Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an ef...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the lead center for NASA's scientific and technical information. The NASA STI Program Office provides ...

Fuzzy fault tree analysis: revisited

This talk will review two case studies that examine the effectiveness of using Fuzzy Top Event Probability (FTEP) over the conventional approach. Case study one relates to flash vessel in an ammonia tank, while in case study two ,using fuzzy set theory, the FTEP has been estimated for the existing ammonia storage tank in a large fertilizer complex located in Mumbai, India. In addition, a new fo...
