Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

Advanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

All Graphs of Order n with Distinguishing Number n−1 or n − 2

Theory and Applications of Graphs
Let G be a simple connected graph. The distinguishing number of G, denoted by D(G), is the least integer d such that G has a vertex d-labeling preserved only by the trivial automorphism.

On the partition dimension of circulant graph Cn(1, 2, 3, 4)

, 2023
Let Λ = {B1,B2, . . . ,Bl} be an ordered l-partition of a connectedgraph G(V (G),E(G)). The partition representation of vertex x withrespect to Λ is the l-vector, r(x|Λ) = (d(x,B1), d(x,B2), . . . , d(x,Bl)), whered(x,B) = min{d(x, y)

Partitions in More than One Dimension

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1956
Summary Several important properties are derived for the new partitional functions introduced by Fisher (1950) in his enumeration of the number of partitions of an integer in an arbitrary number of dimensions. These functions readily lead to the enumeration of the number of partitions of an integer in more than one dimension and with ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

The partition dimension of origami graphs and its barbell

Indonesian Journal of Combinatorics
The origami graph, On, n≥3, is a graph formed by a central cycle with origami folds, where each fold consists of two C3 cycles. The barbell origami graph, BOn for n≥3 is obtained by copying a On and connecting two graphs with a bridge.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Enumeration of odd-dimensional partitions modulo 4

The American Journal of Combinatorics
The number of standard Young tableaux on a partition shape \(\lambda\) is called the dimension of the partition. Partitions with odd dimensions were enumerated by McKay and were further characterized by Macdonald in the 1970s.

On the partition dimension of unicyclic graphs

, 2011
Given an ordered partition $Π=\{P_1,P_2, ...,P_t\}$ of the vertex set $V$ of a connected graph $G=(V,E)$, the \emph{partition representation} of a vertex $v\in V$ with respect to the partition $Π$ is the vector $r(v|Π)=(d(v,P_1),d(v,P_2),...,d(v,P_t))$, where $d(v,P_i)$ represents the distance between the vertex $v$ and the set $P_i$.
