Data Augmentation for the POD Formulation of the Parametric Laminar Incompressible Navier–Stokes Equations

International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.
ABSTRACT A posteriori reduced‐order models (ROM), for example, based on proper orthogonal decomposition (POD), are essential to affordably tackle realistic parametric problems. They rely on a trustful training set, that is a family of full‐order solutions (snapshots) representative of all possible outcomes of the parametric problem.

Time Interleaving in the Analogue Circuitry of Oversampled Digital‐to‐Analogue Converters: Proof of Concept

Electronics Letters, Volume 61, Issue 1, January/December 2025.
Time interleaving techniques allow parallel structures to operate at reduced speeds. This work investigates the feasibility of employing a parallel array of low‐speed DACs. Experimental results demonstrate that the proposed approach exhibits the characteristics required for high‐frequency transmitter applications ABSTRACT Digital‐to‐analog converters ...

Shading Nets: A Current Viticultural Strategy to Mitigate the Negative Impacts of Global Warming on Grape and Wine Quality

Australian Journal of Grape and Wine Research, Volume 2025, Issue 1, 2025.
Viticulture is facing important challenges in cultivation and management since grapevines are particularly vulnerable to changes in environmental conditions. Heat waves, extreme temperatures, and unpredictable weather patterns have become more frequent in wine‐growing regions, creating an uncertain future for growers.

Using Artificial Neural Networks for Classification of Composition and Biomass Species for Energy Based on Thermogravimetric Data

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The thermogravimetric analysis (TGA) data of wood present a very similar layout, which makes it difficult to obtain information on components or types of biomass with traditional techniques, which are generally based on the decrease in weight of the sample at specific temperature values.

A first‐order hyperbolic arbitrary Lagrangian Eulerian conservation formulation for non‐linear solid dynamics

International Journal for Numerical Methods in Engineering, Volume 125, Issue 15, 15 August 2024.
Summary The paper introduces a computational framework using a novel Arbitrary Lagrangian Eulerian (ALE) formalism in the form of a system of first‐order conservation laws. In addition to the usual material and spatial configurations, an additional referential (intrinsic) configuration is introduced in order to disassociate material particles from mesh
