Discrete modified projection methods for Urysohn integral equations with Green’s function type kernels

open access: yesMathematical Modelling and Analysis, 2020
In the present paper we consider discrete versions of the modified projection methods for solving a Urysohn integral equation with a kernel of the type of Green’s function.

Darboux transforms on Band Matrices, Weights and associated Polynomials

open access: yes, 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.

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

open access: yesAdvanced 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

open access: yesAdvanced Science, EarlyView.
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.

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

open access: yesAgribusiness, 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.

Orthogonal Polynomials for a Class of Measures with Discrete Rotational Symmetries in the Complex Plane [PDF]

open access: yes, 2015
We obtain the strong asymptotics of polynomials $$p_n(\lambda )$$pn(λ), $$\lambda \in {\mathbb {C}}$$λ∈C, orthogonal with respect to measures in the complex plane of the form $$\begin{aligned} \hbox {e}^{-N(|\lambda |^{2s}-t\lambda ^s-\overline{t ...
