Ndimensional probability density function transfer and its aplication to colour transfer
(2005)This article proposes an original method to estimate a continuous transformation that maps one Ndimensional distribution to another. The method is iterative, nonlinear, and is shown to converge. Only 1D marginal distribution ... 
A new global estimation algorithm and its application to retrieval in sport events
(IEEE, 2001)We propose a novel global motion estimation technique based on weighted gradient and displaced frame difference (DFD) associated with Wiener estimation. Then, we apply this technique to parse events of a high level of ... 
A noise adaptive symbol timing synchronization algorithm for software radio receivers
(2004)Software radio promises tremendous benefits from both commercial and military standpoints. Currently, there are a number of different 'shades' of software radio based on the use of FPGAs, DSP chips or generalpurpose ... 
Nonparametric wavelet based texture synthesis
(2005)This paper presents a new algorithm for synthesising image texture. Texture synthesis is an important process in image postproduction. Previous approaches can be classified as either parametric or nonparametric. Of these ... 
Nonexponential dielectric relaxation dynamics in supercooled liquid and glassy states of isoamyl bromide and 2methylpentane mixtures
(American Institute of Physics, 2001)The dielectric spectra of mixtures of the polar solute isoamyl bromide in 2methylpentane have been investigated in the frequency range 1 mHz to 1 MHz and in the temperature range approaching the glass transition temperature. ... 
Nonlinear dielectric relaxation and dynamic Kerr effect in a strong dc electric field suddenly switched on: Exact solutions for the threedimensional rotational diffusion model
(American Physical Society, 1996)The infinite hierarchy of differentialrecurrence relations for ensemble averages of the spherical harmonics pertaining to the noninertial rotational Brownian motion of an ensemble of polar and anisotropically ... 
Nonlinear impedance of a microwavedriven Josephson junction with noise
(American Physical Society, 2000)The nonlinear impedance of a point Josephson junction is calculated under various conditions for the resistively shunted junction model in the presence of noise. The calculation proceeds by solving the Langevin equation ... 
Nonlinear noninertial response of a Brownian particle in a tilted periodic potential to a strong ac force
(American Physical Society, 2000)The solution of the Langevin equation describing the dynamics of a Brownian particle in a tilted periodic potential in the overdamped limit is obtained in terms of a matrix continued fraction, allowing us to evaluate ... 
Nonlinear noninertial response of a quantum Brownian particle in a tilted periodic potential to a strong ac force as applied to a point Josephson junction

Nonlinear noninertial response of a quantum Brownian particle in a tilted periodic potential to a strong ac force as applied to a point Josephson junction
(2009)The normal phase diffusion problem in magnetic resonance imaging (MRI) is treated by means of the Langevin equation for the phase variable using only the properties of the characteristic function of Gaussian random variables. ... 
Nonlinear response of dipolar systems to superimposed ac and dc bias fields
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2016)The main purpose of this thesis is to study the nonlinear ac stationary response of dipolar systems to superimposed ac and dc bias fields via the rotational Brownian motion model. In this way we investigate (i) the nonlinear ... 
Nonlinear response of permanent dipoles in a uniaxial potential to alternating fields
(American Physical Society, 2005)It is shown how the existing theory of the dynamic Kerr effect and nonlinear dielectric relaxation based on the noninertial Brownian rotation of noninteracting rigid dipolar particles may be generalized to take into account ... 
A Note on the Convergence Analysis of LMS Adaptive Filters with Gaussian Data
(ISI Web of Science, 1988)Necessary and sufficient conditions fur the convergence of LMS adaptive filters with Gaussian data have been established by Horowitz and Senne [3], with the recent support of Feuer and Weinstein [4]. A feature of both ...
