Predictive Assessment of Progressive Damage in Mechanically Fastened Glass–Epoxy Composites

open access: yesPolymer Composites, EarlyView.
Progressive damage in mechanically fastened glass–epoxy composites. ABSTRACT Ensuring the structural integrity of advanced composites necessitates precise methodologies for forecasting the onset and progression of damage. This research focused on the predicting progressive damage (PD) for riveted joints composite laminates employing a combined ...

Propagation of internal gravity waves: Optimal vertical discretisation and grid design based on numerical error analysis

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.

Pointwise Reconstruction of Wave Functions from Their Moments through Weighted Polynomial Expansions: An Alternative Global-Local Quantization Procedure

open access: yesMathematics, 2015
Many quantum systems admit an explicit analytic Fourier space expansion, besides the usual analytic Schrödinger configuration space representation. We argue that the use of weighted orthonormal polynomial expansions for the physical states (generated ...

The Macroeconomic Drivers of Carbon Emissions in East Africa: Capital‐Driven Versus Trade‐Driven Globalization

open access: yesSustainable Development, EarlyView.
ABSTRACT East Africa has recorded strong economic growth over the past three decades alongside a steady rise in carbon emissions, raising concerns about whether the region can sustain growth without worsening environmental pressures. This study incorporates key macroeconomic drivers of carbon emissions using panel data for 9 countries from 1990 to 2023,

A good and computationally efficient polynomial approximation to the Maier–Saupe nematic free energy [PDF]

open access: yes, 2011
A new computational strategy is proposed to approximate, with a simple but accurate expression, the Maier–Saupe free energy for nematic order. Instead of the traditional approach of expanding the free energy with a truncated Taylor series, we employ a ...

The Taylor’s Polynomial Apply to Studies of Physics

open access: yesJournal of Physics: Conference Series, 2021
Abstract The tool of studies of physical is produce by the theory of mathematics in general; it can make a relation of equation between physical quantities and other physical quantities, so the mathematics is importance in studies of physics.

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

open access: yesWind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

A Detailed and Comprehensive Account of Fractional Physics‐Informed Neural Networks: From Implementation to Efficiency

open access: yesArtificial Intelligence for Engineering, EarlyView.
Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.
