Seismic probabilistic risk assessment is performed to compute the mean annual frequency of unacceptable performance.
(a) shows the fraction (averaged annual frequency) of sea ice leaving Fram Strait that originates from shallow shelf areas with less than 30 m water depth.
The outcome of this integration process results in values of mean annual frequency of exceeding pre-defined performance levels.
These two measures are the confidence levels for satisfying the desired performance levels at given hazard levels and mean annual frequency of exceeding a specified structural capacity.
However, the annual frequency of attacks was very low and, moreover, an important number of the attacks could have been committed by dogs rather than wolves.
Design guidelines aim to prevent impact by specifying a required minimum clearance to stop (CS) with a low annual frequency of exceedance.
The annual frequency of inclusion to the enalapril or candesartan group from 1999 to 2007 reflects these changes; by a relatively higher use of enalapril from 2005 (data in Supplementary Table S3).
A comparison of government and industry data shows that the annual frequency of police-reported traffic deaths per million registered vehicles in China appears to be roughly six times as high as in the United States.
Main Outcome Measures: Measures included the annual frequency of visits to practitioners of traditional and Western medicine as well as ratings of the importance of seven factors in choosing what type of practitioner to use.
In the research project MAGS (Microseismic Activity of Geothermal Systems) a simple model was developed to determine seismic hazard as the annual frequency of the exceedance of ground motion of a certain size.
Also from the standpoint of a probabilistic seismic performance based design, the vertical irregularities increase the mean annual frequency of exceeding the GI performance level by about 5%to30%0%.
