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.

Application of Non-stationary Extreme Value Analysis to Satellite-Observed Sea Surface Temperature Data for Past Decades

open access: yesFrontiers in Marine Science, 2022
Extreme value analysis (EVA) has been extensively used to understand and predict long-term return extreme values. This study provides the first approach to EVA using satellite-observed sea surface temperature (SST) data over the past decades ...

Accounting for choice of measurement scale in extreme value modeling [PDF]

open access: yes, 2010
We investigate the effect that the choice of measurement scale has upon inference and extrapolation in extreme value analysis. Separate analyses of variables from a single process on scales which are linked by a nonlinear transformation may lead to ...

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 ...

Extreme Value Analysis

open access: yesRevstat 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

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.

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

open access: yesRemote 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 ...

Remaining Life Analysis of Pipeline Gas with Extreme Value Theory

open access: yesJournal of Materials Exploration and Findings
Energy and chemical companies use pipelines to transfer oil, gas, and other materials from one place to another, within and between their plants. Pipeline integrity is an important concern because pipeline leakage could result in serious economic or ...
