Process‐Informed Analysis of As‐Built Metal Additive Surface Features
Advanced Engineering Materials, EarlyView.This article introduces a novel method for feature‐based surface texture characterisation directly incorporating manufacturing variables into the feature extraction workflow. This marks a major step towards identifying process‐specific surface properties and their influence on part function and hence a holistic understanding of process–structure ...

HT-graphs: centers, connected r-domination and Steiner trees [PDF]
Computer Science Journal of Moldova, 1993 HT-graphs have been introduced in [11] and investigated with respect to location problems on graphs. In this paper two new characterizations of these graphs are given and then it is shown that the central vertex, connected r-domination and Steiner trees ...

Independence and Connectivity of Connected Domination Critical Graphs
, 2019 A graph $G$ is said to be $k$-$ _{c}$-critical if the connected domination number $ _{c}(G) = k$ and $ _{c}(G + uv) < k$ for every $uv \in E(\overline{G})$. Let $ , $ and $ $ be respectively the minimum degree, the connectivity and the independence number. In this paper, we show that a $3$-$ _{c}$-critical graph $G$ satisfies $ \leq + 2$.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
