Atom-bond connectivity index and diameter of graphs

Journal 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.

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

Atmosphere, 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 ...

Extreme Value Analysis

Revstat Statistical Journal, 2016
Extreme value theory is dedicated to characterise the behaviour of the extreme observations. The interest is then focused in the tails of the underlying distribution.

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

Economies, 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.

On Optimization and Extreme Value Theory [PDF]

Methodology And Computing In Applied Probability, 2003
A stochastic optimiser is an algorithm ruled by probabilistic procedures which aims at finding the optimum point of an objective function. The authors study the fit of the optimization outcomes to an extreme value distribution and suggest that the parameters of that distribution characterize the performance of the optimiser.

The Spatial Different Order Derivative Method of Gravity and Magnetic Anomalies for Source Distribution Inversion

Remote Sensing, 2021
Gravity and magnetic measurements are common remote sensing strategies to obtain the property change of observed targets. Nowadays, the characteristic value of the derivatives of gravity and magnetic anomalies is commonly used to detect the source ...

General (p,q)-mixed projection bodies

Open Mathematics, 2020
In this article, the general (p,q)-mixed projection bodies are introduced. Then, some basic properties of the general (p,q)-mixed projection bodies are discussed, and the extreme values of volumes of the general (p,q)-mixed projection bodies and their ...

Bi-free extreme values

Journal of Functional Analysis, 2020
In this paper, we continue Voiculescu's recent work on the analogous extreme value theory in the context of bi-free probability theory. We derive various equivalent conditions for a bivariate distribution function to be bi-freely max-infinitely divisible.
