Morphology, mechanical properties and vibration damping properties of polyurea/GNP nanocomposites. ABSTRACT Studying structural dynamics of polyurea (PU) is pivotal to analyze its vibration‐damping features. In this study, a graphene‐reinforced PU coating with enhanced mechanical and damping properties was developed.

ABSTRACT Major accidents causing fatalities and significant environmental and asset damage continue to occur in high‐hazard industries, despite regulatory requirements and organisational mitigation measures. The Hazard and Operability (HAZOP) study is a widely used risk assessment method to identify hazards and implement mitigation measures, but it has

Abstract The downward influence of extreme stratospheric events is typically described by the evolution of the Northern Annular Mode (NAM) across atmospheric levels. However, the dynamics and uncertainty in vertical coupling are not fully resolved. By applying the linear inverse model (LIM) to daily, multi‐level NAM indices from reanalysis and CMIP6 ...

ABSTRACT An efficient method for solving large eigenvalue problems efficiently can be developed using hyper‐reduced order models, such as those arising from the LU Proper Orthogonal Decomposition (LUPOD). The LUPOD employs dominant orthogonal modes along with a flexible number of collocation points to establish a reduced scalar product, thereby ...

On the Modeling of Irreversibility by Relaxator Liouville Dynamics
A general approach to modeling irreversibility starting from microscopic reversibility is presented. A relaxator that breaks reversibility condenses in the Liouville operator of the relevant degrees of freedom. The irreversible relaxator Liouville equation contains memory effects and initial correlations of all degrees of freedom. Stationary states are

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

Convergence properties of dynamic mode decomposition for analytic interval maps
Abstract Extended dynamic mode decomposition (EDMD) is a data‐driven algorithm for approximating spectral data of the Koopman operator associated to a dynamical system, combining a Galerkin method with N$N$ functions and a quadrature method with M$M$ quadrature nodes.

Rapid growth in e‐commerce has intensified the need for suppliers that align with sustainability objectives rather than focusing solely on cost and delivery speed. To address this challenge, the study applies an integrated AHP–TOPSIS framework in which Analytic Hierarchy Process assigns criterion weights—Environmental Impact (0.633), Lead Time (0.260),
