Probability density function of roll amplitude for parametric rolling using moment equation [PDF]

open access: yesBulletin of The Japan Society of Naval Architects and Ocean Engineers
The version of record of this article, first published in Journal of Marine Science and Technology (Japan), is available online at Publisher’s website: https://doi.org/10.1007/s00773-024-01006-2. For the ship stability estimation and ship design, it is helpful to know the probability of the roll amplitude exceeding a certain threshold. Therefore, it is

Probability density function of amplitude decay constant on meteor burst communication channel

open access: yesElectronics Letters, 1991
Lack of accurate characterisation for the amplitude decay constant on the meteor burst channel makes most existing analytical methods of systems on this channel approximate. It is shown that the probability density function of the amplitude decay constant can be approximated by the log-normal density. An expression for the density of the burst duration

Failure Rate Model of Materials under Uncertain Constant Amplitude Cyclic Load

open access: yesMetals, 2022
Failure rate is an important reliability index of mechanical components. Failure rate is usually used to characterize the degradation rule of material performance under the cyclic load, which is critical to fatigue life prediction as well as reliability ...

Probability density functions of amplitude-modulatedrandom signals

open access: yesElectronics Letters, 1998
The probability density function arising from multiplication of two independent random variables has been extensively treated by statisticians, yet some common signal processing product situations have not been analysed. An important example of this omission is the amplitude modulation of a Gaussian process.

Amplitude of Probability Density Function (APDF) of Vibration Response as a Robust Tool for Gearbox Diagnosis [PDF]

open access: yesStrain, 2012
Abstract:  A ‘Go’ or ‘No Go’ assessment is a safety requirement for quick and robust estimation of the condition of gearboxes used in helicopters and other critical machines. A range of vibration‐based condition indicators (CIs) has been developed to meet this requirement.

Modelling and control of the flame temperature distribution using probability density function shaping [PDF]

open access: yes, 2006
This paper presents three control algorithms for the output probability density function (PDF) control of the 2D and 3D flame distribution systems. For the 2D flame distribution systems, control methods for both static and dynamic flame systems are ...

A Relational Formulation of Quantum Mechanics

open access: yesScientific Reports, 2018
Non-relativistic quantum mechanics is reformulated here based on the idea that relational properties among quantum systems, instead of the independent properties of a quantum system, are the most fundamental elements to construct quantum mechanics.
