Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Discrete Mathematics, 2001 An orientation of a graph \(H\) is a digraph obtained from \(H\) by giving to each edge one of its two possible orientations. A digraph \(G\) is an oriented graph if it is an orientation of some graph \(H\). An oriented \(k\)-coloring of an oriented graph \(G\) is a partition of the vertex set of \(G\) into \(k\) color classes such that no two adjacent

The hull number of an oriented graph
International Journal of Mathematics and Mathematical Sciences, 2003 We present characterizations of connected graphs G of order n≥2 for which h+(G)=n. It is shown that for every two integers n and m with 1≤n−1≤m≤(n2), there exists a connected graph G of order n and size m such that for each integer k with 2≤k≤n, there ...

Colourings of $(m, n)$-coloured mixed graphs [PDF]
Discrete Mathematics & Theoretical Computer ScienceA mixed graph is, informally, an object obtained from a simple undirected graph by choosing an orientation for a subset of its edges. A mixed graph is $(m, n)$-coloured if each edge is assigned one of $m \geq 0$ colours, and each arc is assigned one of ...

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Orienting graphs to optimize reachability [PDF]
Information Processing Letters, 1997 The paper focuses on two problems: (i) how to orient the edges of an undirected graph in order to maximize the number of ordered vertex pairs (x,y) such that there is a directed path from x to y, and (ii) how to orient the edges so as to minimize the number of such pairs. The paper describes a quadratic-time algorithm for the first problem, and a proof

New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
Advanced Engineering Materials, EarlyView.This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...
