Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Predicting the Effects of Customized Corneal Cross-Linking on Corneal Geometry

Investigative Ophthalmology & Visual Science
Purpose To validate an existing finite element model (FEM) for predicting the flattening effect of corneal cross-linking (CXL) in a clinical scenario and to use this model to investigate the parameters that most influence CXL-induced flattening effects.Methods Retrospective data were collected from two clinical cohorts, each with 20 patients receiving ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Geometrical intuition and the learning and teaching of geometry

, 2004
Intuition is often regarded as essential in the learning of geometry, but how such skills might be effectively developed in students remains an open question.

Spaces becoming noncommutative [PDF]

, 2010
Noncommutative geometry has developed over the last three decades building up a large collection of examples and tools which have deep connections with various areas of mathematics and physics. In many situations geometric information which is di cult to

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

PLASMA WALL TRANSITION AND EFFECTS OF GEOMETRY IN PRESHEATH

East European Journal of Physics, 2017
When plasma interacts with the wall of a conductor, electrons due to high mobility reach the wall first and develop negative potential on the wall and very near to the wall plasma is divided into sheath and presheath regions.

Linking dynamics, geometry, and environmental challenges

SeMA Journal
Abstract This article reviews the application of geometric ideas, originally developed by Poincaré in the context of celestial mechanics, to address transport problems in oceanic environments. The Lagrangian descriptor tool is reviewed and used to visualise the geometric structures that reveal key transport features in three ...
