In recent years, Many manufacturing industries for promoting their efficiency have tended to use the automatic manufacturing systems. Expanding automatic systems and to increase their complexity are representing the necessity of studying a proper functional quality and using reliable equipment in such systems more than ever. In this direction, the technique of fault tree analysis (FTA), along w...

The 2008 Wells earthquake occurred on a northeast-striking, southeast-dipping fault that is clearly delineated by the aftershock swarm to a depth of 10-12 km below sea level. However, Cenozoic rocks and structures around Wells primarily record east-west extension along northto north-northeast-striking, west-dipping normal faults that formed during the middle Miocene. These faults are responsibl...

CURRENT SCIENCE, VOL. 93, NO. 10, 25 NOVEMBER 2007 1422 *For correspondence. (e-mail: [email protected]) vertical measurements. Also, the time taken by the different stochastic methods is compared. The longer data spans give reliable results as well as less standard deviation for residuals. Using the single-frequency receiver, the standard deviation of the residuals is the same for all three sto...

the presence of radon in drinking water causes health risks associated with exposure from both inhalation and ingestion. since the studies show that faults near the water resources have a critical effect on the concentration of radon, kouhbanan active fault zone, to find water resources  with high radon concentration was chosen for the following investigation. water samples were taken from all ...
