Paper Count: In this method we estimate life distribution function of whole structure using the asymptotic Extreme Value EV distribution of Type I, or Gumbel theory.

These tools contain many more EV related functions. That said: none of these tools is NCL either! The Gilleland et al reference below provides an overview of selected EV software. Extreme value theory EVT is a branch of statistics dealing with the extreme deviations from the median of probability distributions. There exists a well elaborated statistical theory for extreme values.

Extreme value theory or extreme value analysis EVA is a branch of statistics dealing with the extreme deviations from the median of probability distributions. It seeks to assess, from a given ordered sample of a given random variable, the probability of events that are more extreme than any previously observed. Extreme value analysis is widely used in many disciplines, such as structural engineering , finance, earth sciences , traffic prediction, and geological engineering. For example, EVA might be used in the field of hydrology to estimate the probability of an unusually large flooding event, such as the year flood. Similarly, for the design of a breakwater , a coastal engineer would seek to estimate the year wave and design the structure accordingly. The first method relies on deriving block maxima minima series as a preliminary step. In many situations it is customary and convenient to extract the annual maxima minima , generating an "Annual Maxima Series" AMS.

Emil Julius Gumbel. Then, the strength of a given specimen is determined by its weakest point. The term strength is meant to be quite general in scope: we may have in mind mechanical strength, electrical strength, ability to stop the passage of light rays or to prevent the diffusion of a gas, resistance of painted specimens to the corrosive effects of the atmosphere, or perhaps the life span or the intervals between repairs of a device which ceases to function when any one of a number of vital parts breaks down. But it is erroneous to assume that all distributions are normal or tend to normality. Within the theory of extreme values, most distributions are skewed, and do not cease to be skewed if the sample sizes are increased.

Росио через силу улыбнулась и подошла к постели. Но, посмотрев на распростертую на простынях громадную тушу, почувствовала облегчение. То, что она увидела пониже его живота, оказалось совсем крошечным. Немец схватил ее и нетерпеливо стянул с нее рубашку.

- Мы должны позвать людей на помощь. Нам обоим грозит опасность. Сьюзан не верила ни единому его слову.

- Он опять замолчал. Сьюзан ждала продолжения, но его не последовало. - Больше трех часов. Стратмор кивнул. Она не выглядела взволнованной.
