Studies on the Method of Orthogonal Collocation II. An Efficient Numerical Method for the Solution of the Transient Heat Conduction Problem

open access: yesJournal of King Saud University: Engineering Sciences, 1999
An efficient numerical method for the solution of the transient heat conduction problem is developed using the orthogonal collocation method. The method is based on dividing the domain of temperature change into two zones; a zone for which the ...

A collocation method for solving integral equations [PDF]

open access: yesInternational Journal of Computing Science and Mathematics, 2009
A collocation method is formulated and justified for numerical solution of the Fredholm second-kind integral equations. As an application the Lippmann-Schwinger equation is considered. The results obtained provide an error estimate and a justification of the limiting procedure used in the earlier papers by the author, dealing with many-body scattering ...

Food System Through the Lens of a Circular Society: A Transdisciplinary Approach to Integrating Literature and Practice

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular society (CS) conceptualises circularity as a multi‐level governance transformation involving the redistribution of authority, responsibility and coordination across socio‐institutional systems. Yet the concept remains insufficiently operationalised in empirical research.

Discursive Governance and Development Goals: A Performative Theory of Corporate Purpose in Sustainability Discourse

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study theorises and empirically tests performative purpose alignment theory (PPAT), which conceptualises corporate purpose as a performative artefact materialised through discursive and multimodal signals. To operationalise this, we introduced the SDG–Purpose Alignment Index (SPAI), a computational construct that quantifies the thematic ...

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

open access: yesChemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...

A collocation point sampling method for solving the Helmholtz equation using physics-informed neural networks

open access: yesMeitian dizhi yu kantan
BackgroundIn the field of seismic wavefield simulation, physics-informed neural networks (PINNs) have emerged as a new method for efficiently solving the Helmholtz equation due to their characteristic of grid-free computation.
