Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

On Subdivision of Cycles with Two Blocks in Chromatic Digraphs Spanned by Hamiltonian Directed Paths

Mathematics
Let C be an oriented cycle with two blocks and let n denote the number of its vertices. We show that every (n+2)-chromatic digraph spanned by a Hamiltonian directed path contains a subdivision of C. This bound is tight.

Subdivisions of Transitive Tournaments

European Journal of Combinatorics, 2000
A subdivision of a digraph is a digraph obtained by replacing arcs by directed paths (in the same direction as the arcs). It is proved that, for \(r\geq 2\) and \(n\geq n(r)\), every digraph with \(n\) vertices and more arcs than the \(r\)-partite Turán graph \(T(r,n)\), contains a subdivision of the transitive tournament on \(r+1\) vertices. Moreover,

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 ...

Subdivision and graph eigenvalues

Linear Algebra and its Applications
This paper investigates the asymptotic nature of graph spectra when some edges of a graph are subdivided sufficiently many times. In the special case where all edges of a graph are subdivided, we find the exact limits of the $k$-th largest and $k$-th smallest eigenvalues for any fixed $k$.

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Key Technology and Application of Long-Term Subdivision Water Injection in Chengdao Oilfield

Shiyou jixie, 2019
In the water injection in Chengdao Oilfield, poor effect of separate layer stimulation, inferior reliability of separate layer water injection string and short period of plug removal were encountered, which cannot meet the volume and accuracy ...

Weakly Regular Subdivisions [PDF]

Discrete & Computational Geometry, 2011
A finite subset \(A\) of \(\mathbb R^d\) whose affine hull has full dimension is called a \(d\)-dimensional point configuration. A collection of subsets of \(A\) whose convex hulls form a polyhedral complex is called a polyhedral subdivision of \(A\).

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,
