Darboux transforms on Band Matrices, Weights and associated Polynomials

, 1999
Classically, it is well known that a single weight on a real interval leads to orthogonal polynomials. In "Generalized orthogonal polynomials, discrete KP and Riemann-Hilbert problems", Comm. Math. Phys. 207, pp.

Recurrence relations for connection coefficients between q-orthogonal polynomials of discrete variables in the non-uniform lattice X(s) = q2s [PDF]

, 1996
We obtain the structure relations for q-orthogonal polynomials in the exponential lattice q 2s and from that we construct the recurrence relation for the connection coe cients between two families of polynomials belonging to the classical class of ...

Factors Driving Battery and Solar Purchase Decision of Residents: a Behavioural Choice Experiment Using a Hybrid Discrete Choice and Latent Variable Model

Advanced Sustainable Systems, EarlyView.
This article explores what drives households to adopt solar PV and battery systems in South East Queensland. Using hybrid discrete choice experiments, it reveals distinct adopter profiles and highlights cost, system size, and energy independence as key motivators.

Large Depth-of-Field, Large Eyebox, and Wide Field-of-View Freeform-Holographic Augmented Reality Near-Eye Display. [PDF]

Adv Sci (Weinh)
This study proposes an augmented reality (AR) near‐eye display system that simultaneously achieves a large depth‐of‐field (DOF) from 0.25 to 10 m, a wide 50° field‐of‐view (FOV), and a 10 mm × 10 mm viewing eyebox, while maintaining high display performance, good optical see‐through viewing capability, and a compact system form factor.

On the properties for modifications of classical orthogonal polynomials of discrete variables [PDF]

Journal of Computational and Applied Mathematics, 1995
We consider a modi cation of moment functionals for some classical polynomials of a discrete variable by adding a mass point at x = 0. We obtain the resulting orthogonal polynomials, identify them as hypergeometric functions and derive the second order di erence equation which these polynomials satisfy.

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.

New Stability Criteria for Discrete Linear Systems Based on Orthogonal Polynomials

Mathematics, 2020
A new criterion for Schur stability is derived by using basic results of the theory of orthogonal polynomials. In particular, we use the relation between orthogonal polynomials on the real line and on the unit circle known as the Szegő transformation ...

A distributional study of discrete classical orthogonal polynomials

Journal of Computational and Applied Mathematics, 1995
This paper is a systematic study of discrete classical orthogonal polynomial sequences (Charlier, Meixner, Hahn) from a distributional viewpoint. The properties for the continuous case orthogonal polynomial sequences (denoted here by DOPS; Hermite, Laguerre, Jacobi, Bessel) can a.o. be derived from a distributional differential equation \(D (\varphi u)
