Extreme Value Theory and the Solar Cycle [PDF]

open access: yes, 2007
We investigate the statistical properties of the extreme events of the solar cycle as measured by the sunspot number. The recent advances in the methodology of the theory of extreme values is applied to the maximal extremes of the time series of sunspots.

Extremal values of continuants [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
The following question was posed by C. A. Nicol: Given an arbitrary set B B of positive integers, find the extremal denominators of regular continued fractions with partial denominators from B B , each element occurring a given number of times. Partial solutions have been given by T. S. Motzkin and E. G.

Spatial Patterns in the Extreme Dependence of Ozone Pollution between Cities in China’s BTH Region

open access: yesAtmosphere, 2023
Ozone pollution in China has become increasingly severe in recent years. Considering the damage that extreme ozone pollution may cause and the fact that the occurrence of extreme ozone pollution among different locations may be related, this paper uses ...

Design Bushfire Selection for Bushfire Protection in Adaptation to Global Warming

open access: yesFrontiers in Mechanical Engineering, 2019
In this article, a risk based approach to design for bushfire protection in view of adaptation to global warming is discussed. The concept of design bushfire is explained in an analogy to design flood or design earthquake in terms of event of prescribed ...

The Optimization of Bayesian Extreme Value: Empirical Evidence for the Agricultural Commodities in the US

open access: yesEconomies, 2021
Bayesian extreme value analysis was used to forecast the optimal point in agricultural commodity futures prices in the United States for cocoa, coffee, corn, soybeans and wheat. Data were collected daily between 2000 and 2020.

Atom-bond connectivity index and diameter of graphs

open access: yesJournal of Hebei University of Science and Technology, 2016
For further study of the numerous nice properties of topological indices in physical and chemical fields, it is worth considering the relation between a degree-based index and a distance-based index.
