A Bayesian Two-Sided Tests on the Mean of the Lognormal Distribution with Known Precision and Quadratic Utilities [PDF]

open access: yesThe Egyptian Statistical Journal, 1977
We are concerned in this article on the problem of deciding whether the mean of the lognormal distribution, μL falls in a certain finite interval ( μL(1),μL(2)) say. Two forms of utility functions were considered and sensitivity analysis carried out.

Testing Taylor’s Law in Urban Population Dynamics Worldwide with Simultaneous Equation Models

open access: yesEconomies, 2023
Knowledge of long-term population trends is still incomplete at the global scale. In this perspective, human and animal ecology has intensively studied the relationship between the Mean (M) size and the Variance (V) of specific attributes of ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Research on Underwater Sound Source Localization Based on NLM-EEMD and FCM-Generalized Quadratic Correlation

open access: yesShock and Vibration, 2022
The accuracy of underwater sound source localization depends on the preprocessing effect of signal denoising and delay estimation performance. In order to meet the needs of high-precision underwater positioning, this article studies a time delay ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Can body volume predict of body weight in Pelibuey ewe lambs? [PDF]

open access: yesCiência Rural
: In traditional sheep production systems in tropical regions, the evaluation and monitoring of animal growth are not commonly practiced. This is primarily attributed to the limited adoption of technology and the high costs associated with acquiring ...

RELATIONSHIP BETWEEN BODY VOLUME AND BODY WEIGHT IN PELIBUEY EWES

open access: yesTropical and Subtropical Agroecosystems, 2021
Background. In terms of animal management, the measurement of body weight (BW) is important in the design of nutrition and health programs. Objective. The objective of the present study was to evaluate the relationship between body volume (BV) and BW in ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Unification Theories: Means and Generalized Euler Formulas

open access: yesAxioms, 2020
The main concepts in this paper are the means and Euler type formulas; the generalized mean which incorporates the harmonic mean, the geometric mean, the arithmetic mean, and the quadratic mean can be further generalized.
