Cost efficiency and UK building societies. An econometric panel-data study employing a flexible fourier functional form [PDF]

open access: yes, 1998
The paper empirically quantifies firm specific 'distribution free' cost efficiency, economies of scale and economies of scope in the UK building society sector between 1990-1995. Both a flexible Fourier and a translog functional form are employed with

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Mathematical aspects of non-Fourier heat equations

open access: yesJournal of Computational and Applied Mechanics, 2022
Due to technological advancement, as materials with complex structures (e.g., metamaterials and foams) appear in practice there is a need to develop advanced thermal models. These are called non-Fourier equations, and all have particular mathematical properties differing from the conventional attributes of Fourier's law. The present paper discusses the

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

On the restriction of the Fourier transform to polynomial curves [PDF]

open access: yes, 2007
We prove a Fourier restriction theorem on curves parametrised by the mapping P(t) = (P1(t),..., Pn(t)), where each of the P1,..., Pn is a real-valued polynomial and t belongs to an interval on which each of the P1,..., Pn "resembles" a ...

Fourier transform spectral interferometry with non-phase stable setups by broadband single shot detection of fs and ps pulses [PDF]

open access: yes, 2017
In this paper, we present a novel approach to Fourier transform spectral interferometry based on single-shot detection of broadband pulses. It allows heterodyne detection with non-phase-stabilised setups, which use ps- and fs-pulsed laser sources.

A new approximate-analytical method to solve non-Fourier heat conduction problems

open access: yesKuwait Journal of Science, 2017
In this paper, the effect of laser as a heat source on a thin film was investigated. The non-Fourier heat conduction modelof Cattaneo-Vernotte was used for thermal analysis of the problem. The thermal conductivity was assumed temperaturedependent, which

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
