Regional Variance‐Based Sensitivity Analysis and a Study of Regional Equifinality

open access: yesRisk Analysis, Volume 46, Issue 10, October 2026.
ABSTRACT Models in risk analysis frequently exhibit nonlinear behavior, thresholds, and regime shifts, which challenge conventional global sensitivity analysis (GSA) paradigms. Classical variance‐based methods quantify input importance over the entire output space, which can mask how these sensitivities vary across regions that are most relevant for ...

Support for Visual Languages Evolution in DSM-platform QReal

open access: yesМоделирование и анализ информационных систем, 2014
Like other software artefacts, DSMLs evolve in time. When a DSML changes, instance models might no longer conform to the new DSML metamodel and hence cannot be manipulated with a modelling tool.

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, Volume 29, Issue 5, Page 975-1017, September 2026.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

A stacking based deep learning framework integrating random search neural architecture search for meniscus tear diagnosis

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Accurate and rapid diagnosis of meniscal tears is crucial for effective management of sports‐related injuries and degenerative knee disorders. Magnetic resonance imaging (MRI) is widely used for meniscus evaluation; however, manual interpretation is time‐consuming and subject to inter‐observer variability.

Artificial intelligence metamodel comparison and application to wind turbine airfoil uncertainty analysis

open access: yesAdvances in Mechanical Engineering, 2016
The Monte Carlo simulation method for turbomachinery uncertainty analysis often requires performing a huge number of simulations, the computational cost of which can be greatly alleviated with the help of metamodeling techniques. An intensive comparative

Generative Design of Energy‐Absorbing Auxetic Metamaterials via Variational‐Autoencoder Latent‐Space Exploration and Nonlinear Finite‐Element Screening

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT Auxetic cellular structures, which exhibit a negative Poisson's ratio, are conventionally designed manually, one topology at a time. This paper presents a generative design framework in which a convolutional variational autoencoder (VAE) with a low computational cost, trained on 31,920 solid isotropic material with penalisation (SIMP ...

Multi-Objective Optimization of Production Objectives Based on Surrogate Model

open access: yesApplied Sciences, 2020
The article addresses an approximate solution to the multi-objective optimization problem for a black-box function of a manufacturing system. We employ the surrogate of the discrete-event simulation model of a batch production system in an analytical ...

Domesticating robots, domesticating language: The hylomorphic paradox of “openness” in large language models

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 2, August 2026.
Abstract This article examines how openness is interpreted in human–LLM interaction through an ethnographic study of a robotics experiment. Focusing on an episode in which a robot produced an unexpected utterance, I analyze how engineers classify the output as inconsequential noise.
