New Characterizations of Discrete Classical Orthogonal Polynomials

open access: yesJournal of Approximation Theory, 1997
In this very nice paper, the authors consider (quasi)orthogonal polynomial sequences [\((Q)OPS\): see (i)] with respect to a regular moment functional \(\sigma\) [see (ii)]. (i) \(\{P_n\}_{n=0}^{\infty}\) polynomials in \(x\) with degree \(P_n=n,\;n\geq 0\) form a \(QOPS\) resp. \(OPS\) if \(\langle \sigma,P_nP_m\rangle = K_n\delta_{nm}\) with \(K_n\in{

Circularity, Sustainability, and the Quality of Coffee Sold via Vending Machines: What Do Italian Consumers Prefer?

open access: yesAgribusiness, EarlyView.
ABSTRACT Vending is an important sector in the daily lives of many people, and coffee is the most frequently consumed product in the European market. Like many other sectors, vending is responding to the challenge of sustainable development by taking various actions, such as offering increasingly ecologically sound coffee while maintaining/improving ...

The Impacts of Health and Environmental Information Nudges on Meat Choices: Where Does Goat Meat Fit?

open access: yesAgribusiness, EarlyView.
ABSTRACT Amidst a recent surge in US goat meat imports to meet growing demand, this study contributes to the meat demand literature by examining consumer preferences for goat meat, a relatively healthy and environmentally friendly alternative to other popular meats.

Expressions of Legendre polynomials through Bernoulli polynomials

open access: yesRevista Técnica de la Facultad de Ingeniería, 2011
A formula for expanding Legendre polynomials in Bernoulli polynomials is considered. The relationship is established by using a formula of finite summation, obtained by applying the discrete orthogonal relation of the modified Lommel polynomials.

The Fractional Orthogonal Derivative

open access: yesMathematics, 2015
This paper builds on the notion of the so-called orthogonal derivative, where an n-th order derivative is approximated by an integral involving an orthogonal polynomial of degree n.

Image analysis using new set of separable two-dimensional discrete orthogonal moments based on Racah polynomials

open access: yesEURASIP Journal on Image and Video Processing, 2017
In this paper, we propose three new separable two-dimensional discrete orthogonal moments baptized: RTM (Racah-Tchebichef moments), RKM (Racah-Krawtchouk moments), and RdHM (Racah-dual Hahn moments).

Uniform Asymptotics for Discrete Orthogonal Polynomials with Respect to Varying Exponential Weights on a Regular Infinite Lattice [PDF]

open access: yes, 2009
We consider the large N asymptotics of a system of discrete orthogonal polynomials on an infinite regular lattice of mesh N1/N, with weight e −NV (x) , where V (x) is a real analytic function with sufficient growth at infinity.

Comparison of DeePMD, MTP, GAP, ACE and MACE Machine‐Learned Potentials for Radiation‐Damage Simulations: A User Perspective

open access: yesAdvanced Intelligent Discovery, EarlyView.
The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Discrete Fourier Analysis and Chebyshev Polynomials with G2 Group

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The discrete Fourier analysis on the 30°-60°-90° triangle is deduced from the corresponding results on the regular hexagon by considering functions invariant under the group G2, which leads to the definition of four families generalized Chebyshev ...
