On the Rayleigh Exponentiated Odd Generalized‐Inverse Exponential Distribution With Properties and Applications

Engineering Reports
This research centers on the creation of an innovative statistical model that extends the inverse exponential (IE) distribution by employing the Rayleigh‐exponentiated odd generalized (REOG) family of distributions, which is designated as the REOG‐IE ...

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐based random forest model to simulate high‐resolution δ18O patterns.

Kurtosis ordering of the generalized secant hyperbolic distribution: a technical note [PDF]

Two major generalizations of the hyperbolic secant distribution have been proposed in the statistical literature which both introduce an additional parameter that governs the kurtosis of the generalized distribution.

Macroeconomic Variables and Income Distribution: Conditional Modeling with the generalized Exponential

, 2000
This paper presents a method of examining the effects of macroeconomic variables on the personal distribution of income over time. The approach involves modeling the complete distribution of income in each year using a flexible functional form from the ...

Odd Log-Logistic Rayleigh Distribution with Applications

In this article, a new extended Rayleigh distribution called the Odd Log-Logistic Rayleigh (OLLR) Distribution is developed. A two parameter distribution derived by incorporating the Rayleigh distribution in the Odd Log-Logistic – Generalized (OLL-G ...

Bayesian estimation under different loss functions for the case of inverse Rayleigh distribution

Kuwait Journal of Science
In this study, the best parameter estimator for the scale parameter (θ) of the inverse Rayleigh distribution was determined based on a comparison of the maximum likelihood estimator (MLE) method, the Bayesian generalized squared error loss function (SELF)

Mellin Transform Based Performance Analysis of FFH M-ary FSK Using Product Combining Against Partial Band Noise Jamming

, 2007
We propose a novel bit error ratio (BER) analysis technique for fast frequency hopping (FFH) assisted M-ary frequency shift keying (MFSK) using product combining (PC), when the channel is contaminated by partial band noise jamming (PBNJ).
