In group B, the lower layer showed a higher gene content than the upper layer, with an overall trend of increasing and then decreasing, with one extreme value. In group C the lower water...

... ) and 10 m mean wind speed ( u 10 ). This paper explored the development of a univariate extreme value-analysis (EVA) sea state( H s and T p ) and extreme wind speed, within the Caribbean Sea. These results will be used as inputs to a numerical model of a floating offshore wind turbine (FOWT). The H...

Different simulation sizes are compared. Different extreme-value prediction methods are applied and the results are compared. Both the peak-over...

.... The distribution disciplinarians of ocean environmental loads are analyzed by the fractal theory and statistical analysis methods. The extreme values of 6-DoF-motions are selected as the characteristic parameters of the output layer. A Long-Short-Term Memory Network (LSTM) deep learning network is established...

... that encounter wave frequency is related to the heading angle of short-crest when calculating none-zero spectral momentum under the combined influence of long and short crest waves. As to the solution of long-term extreme value, to avoid the iterative failure, the Brent method is used to solve the nonlinear...

... distribution fit of the data. Even though this distribution is generally suitable for describing average behaviour, it fails to describe extreme behaviour. This paper adopts extreme value theory (EVT) to assess extreme behaviour of material strength. Evidence is found that the minimum possible material...

... ABSTRACT Data for maximum pit depths obtained from intelligent pigging runs for several older operational water injection pipelines (WIPs) has been used extensively for prediction of likely future pipe wall penetration. Often such data do not fit extreme value distributions very well. Also...
