Laminated Composites Buckling Analysis Using Lamination Parameters, Neural Networks and Support Vector Regression

Latin American Journal of Solids and Structures
This work presents a metamodel strategy to approximate the buckling load response of laminated composite plates. In order to obtain representative data for training the metamodel, some laminates with different stacking sequences are generated using the ...

A Model Based Systems Engineering Framework for Digital Twins in Medical Device Innovation

Systems Engineering, EarlyView.
ABSTRACT Medical device development remains constrained by development processes centered largely in the physical domain. These methods limited early understanding of system behavior and prolonged timelines relative to other innovation pathways. Such limitations increase prototype cycle duration and the number of iterations required to resolve design ...

Intraspecific trait variation responds consistently to global change drivers and mediates herbivory across unrelated plant species

Journal of Ecology, Volume 114, Issue 7, July 2026.
In classic trait‐based approaches, traits reflect different plant strategies that evolved over long‐term evolutionary timescales. The study indicates that these trade‐offs also emerge consistently across populations within single species, yielding similar ecological consequences.

Advanced High-Level Synthesis techniques based on metamodel [PDF]

International Journal of Electronics and Telecommunications
This paper explores advanced techniques in highlevel synthesis (HLS) utilizing metamodel structures. Metamodels act as models of hardware models, generating internal hardware models based on parameter inputs and exploring the solution space to find ...

Global Sensitivity Analysis of Societal Resilience Using Shapley Values and Polynomial Chaos Expansion

Risk Analysis, Volume 46, Issue 7, July 2026.
ABSTRACT Societies worldwide face increasingly complex and interconnected crises that challenge their capacity for resilience. Assessing which structural indicators are most strongly associated with resilience scores requires quantitative methods capable of handling interdependencies, nonlinearities, and limited sample sizes.

Lessons Learned From Using Simple Supervised Learning Tools on Small‐Ensemble Data—Applicability to Tunnel Design and Monitoring

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3397-3411, 10 June 2026.
ABSTRACT Integrating interdisciplinary strategies with artificial intelligence (AI), particularly machine learning (ML), is an effective way of addressing urgent engineering challenges. Therefore, a thorough evaluation of existing methodologies is essential, taking into account their respective strengths, limitations and opportunities.

Design patterns for metamodels [PDF]

Proceedings of the compilation of the co-located workshops on DSM'11, TMC'11, AGERE! 2011, AOOPES'11, NEAT'11, & VMIL'11, 2011
A metamodel is used to define the abstract syntax (i.e., entities, attributes, and relations) of a Domain-Specific Modeling Language (DSML). In addition, a metamodel also defines constraints and static semantics that provide additional information about the modeling language beyond the abstract syntax.
