Quark Wigner distributions and spin-spin correlations
, 2017 We investigate the Wigner distributions for u and d quarks in a light-front quark-diquark model of a proton to unravel the spatial and spin structure. The light-front wave functions are modeled from the softwall AdS/QCD prediction.

Wigner Distributions of Quarks for Different Polarizations
, 2017 We calculate quark Wigner distributions using the light-front wave functions in a dressed quark model. In this model, a proton target is replaced by a simplified spin-1/2 state, namely a quark dressed with a gluon.

Limiting Conditional Distributions: Imprecision and Relation to the Hazard Rate [PDF]
, 2009 Many Markov chains with a single absorbing state have a unique limiting conditional distribution (LCD) to which they converge, conditioned on non-absorption, regardless of the initial distribution.

Quark Wigner distributions using light-front wave functions
, 2017 The quasiprobabilistic Wigner distributions are the quantum mechanical analog of the classical phase-space distributions. We investigate quark Wigner distributions for a quark state dressed with a gluon, which can be thought of as a simple composite and ...

Diesel injector dynamic modelling and estimation of injection parameters from impact response part 2: prediction of injection parameters from monitored vibration [PDF]
, 1996 Part 2 of this paper presents the experimental and analytical procedures used in the estimation of injection parameters from monitored vibration. The mechanical and flow‐induced sources of vibration in a fuel injector are detailed and the features of the

Fitting discrete multivariate distributions with unbounded marginals and normal-copula dependence
, 2009 In specifying a multivariate discrete distribution via the NORmal To Anything (NORTA) method, a problem of interest is: given two discrete unbounded marginals and a target value r, find the correlation of the bivariate Gaussian copula that induces rank ...

A revised discrete pseudo-Wigner distribution and its application to nonstationary signal analyses.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 Recently, several efforts have been directed towards developing a joint time and frequency representation for signal analysis. For a time-varying signal, whether a deterministic transient or nonstationary random signal, the use of a discrete pseudo-Wigner distribution (WD) is especially suitable.
