Modeling of screening effect to number of thermal cycles by investigation of space hardware thermal vacuum test

Nihon Kikai Gakkai ronbunshu, 2016
Thermal vacuum and thermal cycle testing are widely complemented in space flight hardware and components as an effective way to screen out potential defects in manufacture and integration.

Additomultiplicative Cascades Govern Multifractal Scaling Reliability Across Cardiac, Financial, and Climate Systems

Entropy
The generative mechanisms underlying multifractal scaling in complex systems remain a fundamental unsolved problem, limiting our ability to distinguish healthy from pathological dynamics, predict system failures, or understand how scale-invariant ...

Inference for double Pareto lognormal queues with applications [PDF]

, 2008
In this article we describe a method for carrying out Bayesian inference for the double Pareto lognormal (dPlN) distribution which has recently been proposed as a model for heavy-tailed phenomena. We apply our approach to inference for the dPlN/M/1 and

Evo-SETI: A Mathematical Tool for Cladistics, Evolution, and SETI

Life, 2017
The discovery of new exoplanets makes us wonder where each new exoplanet stands along its way to develop life as we know it on Earth. Our Evo-SETI Theory is a mathematical way to face this problem.

Lognormal approximations to Libor market models

, 2002
We study several lognormal approximations for Libor market models, where special attention is paid to their simulation by direct methods and lognormal random fields.

Forms and genesis of species abundance distributions [PDF]

Computational Ecology and Software, 2015
Species abundance distribution (SAD) is one of the most important metrics in community ecology. SAD curves take a hollow or hyperbolic shape in a histogram plot with many rare species and only a few common species. In general, the shape of SAD is largely

On the Existence and Uniqueness of the Maximum Likelihood Estimators of Normal and Lognormal Population Parameters with Grouped Data

Journal of Probability and Statistics, 2009
Lognormal distribution has abundant applications in various fields. In literature, most inferences on the two parameters of the lognormal distribution are based on Type-I censored sample data.

Testing Inverse Gaussian Versus Log Normal [PDF]

The Egyptian Statistical Journal, 1991
The inverse Gaussian distribution has been proposed as a model for distribution of life times. It is considered as an alternative to other observed distributions in particular to the lognormal.

Tsunami Distribution Functions along the Coast: Extended

Journal of Marine Science and Engineering, 2022
The distribution of tsunami runup heights along the coast is studied both theoretically and experimentally using observation data of historical tsunami from 1992 to 2018.
