Abstract: We consider two independent random variables with the given tail asymptotic (e.g. power or exponential). We find tail asymptotic for their sum and product. This is done by some cumbersome bu...
Temperature extremes in the Mediterranean area: trends in the past and assessments for the future
Temperature extremes the Mediterranean area trends the past and assessments the future
font style='font-size:12px;'>

Possible consequences of climate change concern both changes in long-term
mean values of runoff and changes in frequency and magnitude of extreme
runoff events. The physical safety of dams and prote...
