On the Properties of Metamodeling in OWL [PDF]
Journal of Logic and Computation, 2005 A common practice in conceptual modeling is to separate the intensional from the extensional model. Although very intuitive, this approach is inadequate for many complex domains, where the borderline between the two models is not clear-cut. Therefore, OWL-Full, the most expressive of the Semantic Web ontology languages, allows combining the intensional

Advanced Intelligent Discovery, EarlyView.This perspective highlights how knowledge‐guided artificial intelligence can address key challenges in manufacturing inverse design, including high‐dimensional search spaces, limited data, and process constraints. It focused on three complementary pillars—expert‐guided problem definition, physics‐informed machine learning, and large language model ...

An Actor-Oriented and Architecture-Driven Approach for Spatially Explicit Agent-Based Modeling
Complex Systems Informatics and Modeling Quarterly, 2023 Nowadays, there is an increasing need to rapidly build more realistic models to solve environmental problems in an interdisciplinary context. In particular, agent-based and spatial modeling have proven to be useful for understanding land use and land ...

From patterns to predictions: a framework for the spatial epidemiology of wildlife diseases
Ecography, EarlyView.Wildlife diseases pose a significant threat to biodiversity conservation, public health, and livestock. Spatial epidemiology provides a robust framework to understand disease dynamics and guide policy and management. However, the rapid proliferation of spatial methods has largely occurred in isolation across disciplines, leaving the field without a ...

Latin American Journal of Solids and StructuresThis 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 ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Systems Engineering, EarlyView.ABSTRACT Advanced production systems play a vital role in modern society. Such systems are developed and industrialized over multiple years and at great expense. The complexities of these systems are exacerbated in the case of metal additive manufacturing, which involves numerous process variables and relies on various auxiliary systems.

A Passive Time Reversal Method with a Metamodel for Underwater Source Localization
Journal of Marine Science and EngineeringA passive time reversal method with a metamodel (PTR-MM) is proposed to improve underwater source localization under ocean conditions. PTR-MM eliminates model mismatch errors by replacing the conventional sound propagation model with a Kriging metamodel.
