Shaking Table Test-Based Verification of PDEM for Random Seismic Response of Anchored Rock Slopes

open access: yesApplied Sciences
This study systematically verified the applicability and accuracy of the Probability Density Evolution Method (PDEM) in the probabilistic modeling of the dynamic response of anchored rock slopes under random seismic action through large-scale shaking ...

The Linear Probability Density Function of Continuous Random Variables in the Real Number Field and Its Existence Proof

open access: yesMATEC Web of Conferences, 2016
For a continuous random variable in real number field, there must be a distribution and also a probability density function of this random variable. If there is a known function with this random variable as independent variable, its image is a smooth or ...

A mathematical Weibull model altered neuroendocrine control of GH secretion in normal women of advanced reproductive age [PDF]

open access: yesNetwork Biology, 2022
An extreme value distribution, the Weibull distribution is frequently used to model reliability, wind speed, survival, and other data. One of the main reasons for this is its flexibility.

Some probability density functions and their characteristic functions [PDF]

open access: yesMathematics of Computation, 1973
This paper presents, without derivation, several generalized density functions together with their characteristic functions. The densities are expressed variously in terms of special functions such as:

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Simulated Annealing with Gaussian Probability Density Function for Transmission Expansion Planning

open access: yesU.Porto Journal of Engineering, 2015
Simulated Annealing (SA) is a powerful tool for optimization problems that have several local optima. This tool has the ability to escape from a local optima accepting relatively bad solutions for a period and searching for good solutions in your ...

Conditional density estimation with class probability estimators [PDF]

open access: yes, 2009
Many regression schemes deliver a point estimate only, but often it is useful or even essential to quantify the uncertainty inherent in a prediction. If a conditional density estimate is available, then prediction intervals can be derived from it.

Experimental Assessment of ‘subgrid’ scale Probability Density Function Models for Large Eddy Simulation [PDF]

open access: yes, 2012
Filtered density functions (FDFs) of mixture fraction are quantified by analyzing experimental data obtained from two-dimensional planar laser-induced fluorescence scalar measurements in the isothermal swirling flow of a combustor operating at a ...
