IMPULSE moment-by-moment test:An implicit measure of affective responses to audiovisual televised or digital advertisements [PDF]

open access: yes, 2020
IMPULSE is a novel method for detecting affective responses to dynamic audiovisual content. It is an implicit reaction time test that is carried out while an audiovisual clip (e.g., a television commercial) plays in the background and measures feelings ...

Effects of Cage Pocket Shapes on Dynamics of Angular Contact Ball Bearings

open access: yesTribology Online, 2020
The dynamic models of spherical and cylindrical pocket cages are established based on the dynamic wear simulation model of angular contact ball bearings, and the predicted results are in reasonable agreement with the experimental observations.

Ambiguity of the Moment Tensor [PDF]

open access: yes, 2005
An earthquake on a fault separating two dissimilar materials does not have a well-defined moment density tensor. We present a complete characterization of this bimaterial ambiguity in the general case of slip on a fault in an anisotropic medium.

The Nakagami–Weibull distribution in modeling real-life data

open access: yesCumhuriyet Science Journal, 2021
In this article, a four-parameter Nakagami Weibull distributions (NW) is proposed. We study a few statistical properties such as quantile function, moments, moment generating function, entropy, and order statistics have been derived.

L-moments and C-moments

open access: yesStochastic Environmental Research and Risk Assessment, 2000
It is well known that the computation of higher order statistics, like skewness and kurtosis, (which we call C-moments) is very dependent on sample size and is highly susceptible to the presence of outliers. To obviate these difficulties, Hosking (1990) has introduced related statistics called L-moments.

Homotopy moment maps

open access: yes, 2016
Associated to any manifold equipped with a closed form of degree >1 is an `L-infinity algebra of observables' which acts as a higher/homotopy analog of the Poisson algebra of functions on a symplectic manifold.
