On the Distribution of Generating Functions [PDF]

open access: yesBulletin of the London Mathematical Society, 1998
The generating function \(f_P(\alpha)\) associated with the \(k\)th powers is defined by \[ f_P(\alpha)= \sum_{1\leq n\leq P} \exp(i2\pi\alpha n^k). \] For \(\alpha\in (0,1]\), let \(f(\alpha)= P^{-1/2}|f_P(\alpha)|\). It has been conjectured that \[ \int_0^1 f(\alpha)^s d\alpha\sim \Gamma (\tfrac s2+1).

A generalized logistic distribution [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
A generalized logistic distribution is proposed, based on the fact that the difference of two independent Gumbel‐distributed random variables has the standard logistic distribution.

Reliability Evaluation of Cyber–Physical Power Systems Considering Supply- and Demand-Side Uncertainties

open access: yesEnergies, 2021
To reach effective monitoring and control, a physical power grid couples with a communication network and evolves into cyber–physical power systems (CPPS), but this cyber–physical interdependence may exacerbate failure on the physical/cyber side and may ...

Generalized Parton Distributions [PDF]

open access: yes26th Annual Hampton University Graduate Studies Program, Jefferson Lab, May 30, 2011, 2000
Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of the usual parton distributions for the case when long-distance information is accumulated in nondiagonal matrix elements of quark and gluon light-cone operators.

A Generalization of Generalized Beta Distributions [PDF]

open access: yesFinance and Economics Discussion Series, 1998
This paper introduces the "compound confluent hypergeometric" (CCH) distribution. The CCH unifies and generalizes three recently introduced generalizations of the beta distribution: the Gauss hypergeometric (GH) distribution of Armero and Bayarri (1994), the generalized beta (GB) distribution of McDonald and Xu (1995),
