Because the probable maximum events selected in FSAR for nuclear plants may not be the maximum possible events, they could possibly be exceeded by more severe events in the future. As such, there is a need to re-evaluate the other external hazards, especially those associated with the natural phenomena. To ensure that the maximum possible intensities of the natural phenomenon hazards are identi...

Quantitative risk analysis (QRA) of industrial facilities has to take into account multiple hazards threatening critical equipment. Nevertheless, engineering procedures able to evaluate quantitatively the effect of seismic action are not well established. Indeed, relevant industrial accidents may be triggered by loss of containment following ground shaking or other relevant natural hazards, eit...

The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) released in 2014 states that warming of the climate system is “unequivocal,” and it is “extremely likely” that human influence has been the dominant cause. However, public perceptions of anthropogenic climate change have varied widely, and indeed may have been significantly influenced by a disproportionate...

The stochastics two-layer quasi-geostrophic flowmodel is an intermediate system between the single-layer two dimensional barotropic flow model and the continuously stratified three dimensional baroclinic flow model. This model is widely used to investigate basic mechanisms in geophysical flows, such as baroclinic effects, the Gulf Stream and subtropical gyres. A large deviation principle for th...

in some instances, it is inevitable that large amounts of potentially hazardous chemicals like chlorine gas are stored and used in facilities in densely populated areas. in such cases, all safety issues must be carefully considered. to reach this goal, it is important to have accurate information concerning chlorine gas behaviors and how it is dispersed in dense urban areas. furthermore, mainta...

How does driving experience help in the development of situation awareness? A comparison of detection rates of roadway hazards that involved other road users by inexperienced and experienced car drivers and experienced motorcycle riders with car driving experience was conducted under laboratory conditions. Motorcycle rider-drivers, due to their greater breadth of road experiences, were predicte...
