The Kontorovich-Lebedev transform as a map between $d$-orthogonal polynomials

, 2012
A slight modification of the Kontorovich-Lebedev transform is an automorphism on the vector space of polynomials. The action of this $KL_{\alpha}$-transform over certain polynomial sequences will be under discussion, and a special attention will be given

A Dunkl-classical d-symmetric d-orthogonal polynomial set [PDF]

Rendiconti di Matematica e delle Sue Applicazioni, 2010
In this paper, we apply a d-orthogonality preserving operator to the Humbert polynomials to derive a new Dunkl-classical d-orthogonal polynomials generalizing the Humbert ones.

Weak convergence of orthogonal polynomials [PDF]

arXiv, 1994
The weak convergence of orthogonal polynomials is given under conditions on the asymptotic behaviour of the coefficients in the three-term recurrence relation. The results generalize known results and are applied to several systems of orthogonal polynomials, including orthogonal polynomials on a finite set of points.

Who is willing to pay a premium for leafy greens produced by indoor agriculture? A comparative choice experiment with US consumers

Agribusiness, EarlyView.
Abstract Indoor agriculture (IA) presents a pathway to producing leafy greens more sustainably by strictly controlling the growing environment, increasing the efficiency of water and land resources use, reducing pesticide application, and enhancing quality characteristics.

Characterizing digital microstructures by the Minkowski‐based quadratic normal tensor

Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 961-985, 15 January 2023., 2023
For material modeling of microstructured media, an accurate characterization of the underlying microstructure is indispensable. Mathematically speaking, the overall goal of microstructure characterization is to find simple functionals which describe the geometric shape as well as the composition of the microstructures under consideration and enable ...

Alternative Jacobi Polynomials and Orthogonal Exponentials [PDF]

arXiv, 2011
Sequences of orthogonal polynomials that are alternative to the Jacobi polynomials on the interval $[0,1]$ are defined and their properties are established. An $(\alpha,\beta)$-parameterized system of orthogonal polynomials of the exponential function on the semi-axis $[0,\infty)$ is presented.

“Bio‐based Plastic? Hm, I've Never Seen It!”—A mixed‐methods investigation into consumer preferences for different packaging material of fresh apples and tomatoes

Agribusiness, EarlyView.
Abstract Packaging of fresh fruits and vegetables is standard in many grocery stores. This mixed methods study aims to identify the role packaging plays in consumer choice and what packaging material consumers prefer. We analyzed data from quantitative stated preference experiments with a quota sample of 485 consumers living in Germany.

Recurrence Relations for Orthogonal Polynomials on Triangular Domains

Mathematics, 2016
In Farouki et al, 2003, Legendre-weighted orthogonal polynomials P n , r ( u , v , w ) , r = 0 , 1 , … , n , n ≥ 0 on the triangular domain T = { ( u , v , w ) : u , v , w ≥ 0 , u + v + w = 1 } are constructed, where u , v , w

Planar orthogonal polynomials as Type II multiple orthogonal polynomials [PDF]

Journal of Physics A: Mathematical and Theoretical, 2019
We show that the planar orthogonal polynomials with $l$ logarithmic singularities in the potential are the multiple orthogonal polynomials (Hermite-Pad polynomials) of Type II with $l$ measures. We also find the ratio between the determinant of the moment matrix corresponding to the multiple orthogonal polynomials and the determinant of the moment ...

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

Agribusiness, 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 ...
