Lumped and distributed‐parameter pipe model framework for thermal transients: State‐space and transfer function theory and application to multi‐energy systems

open access: yesIET Renewable Power Generation, Volume 17, Issue 1, Page 199-215, 6 January 2023., 2023
Abstract The accurate prediction and simulation of thermal transients in district heating networks is essential for the meaningful analysis of combined heat and power systems. For this purpose, the focus of this paper lies on the development of a consistent and comprehensive modelling framework that links diverse pipe model categories to specific ...

New Integral Transform: Shehu Transform a Generalization of Sumudu and Laplace Transform for Solving Differential Equations

open access: yesInternational Journal of Analysis and Applications, 2019
In this paper, we introduce a Laplace-type integral transform called the Shehu transform which is a generalization of the Laplace and the Sumudu integral transforms for solving differential equations in the time domain. The proposed integral transform is

Characterization of Besov spaces with dominating mixed smoothness by differences

open access: yesMathematische Nachrichten, EarlyView.
Abstract Besov spaces with dominating mixed smoothness, on the product of the real line and the torus as well as bounded domains, are studied. A characterization of these function spaces in terms of differences is provided. Applications to random fields, like Gaussian fields and the stochastic heat equation, are discussed, based on a Kolmogorov ...

Advanced control scheme and dynamic phasor modelling of grid‐tied droop‐controlled inverters

open access: yesIET Renewable Power Generation, EarlyView., 2022
Abstract This paper develops an advanced scheme, modelling, and analysis of power flow control intended for grid‐connected droop‐controlled VSIs within a single‐phase microgrid (MG). The proposed control scheme includes a power calculation method based on an enhanced second‐order generalized integrator frequency‐locked loop (ESOGI‐FLL). Contrary to the

Mesoporous Semi‐Permeable Flexible Polyurethane Membranes: Advancing Bioartificial Pancreas Design for Type 1 Diabetes Treatment

open access: yesMacromolecular Rapid Communications, EarlyView.
Elastomeric mesoporous membranes are developed for the elaboration of a bioartificial pancreas for type 1 diabetes treatment. Using green‐electrospinning followed by thermal and washing post‐treatments, the membranes achieve ≈20 nm pore sizes, biocompatibility, and mechanical strength and flexibility.

Magnetic neutron scattering from spherical nanoparticles with Néel surface anisotropy: analytical treatment

open access: yesJournal of Applied Crystallography, Volume 55, Issue 6, Page 1475-1487, December 2022., 2022
The magnetization profile and the ensuing magnetic neutron scattering signal from an inhomogeneously magnetized spherical nanoparticle with Néel surface anisotropy are derived analytically.The magnetization profile and the related magnetic small‐angle neutron scattering cross section of a single spherical nanoparticle with Néel surface anisotropy are ...
