Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Bathy-morphological setting of the Submarine Pausanias Volcanic Field, South Aegean Active Volcanic Arc

open access: yesJournal of Maps, 2018
High-resolution swath-bathymetry has been acquired during recent surveys in Saronikos Gulf, near the densely populated city of Athens. This paper presents the first detailed bathymetric map, at a scale of 1:12,000, of the active Submarine Pausanias ...

Sociological indices: Methodological reflection on the construction patterns

open access: yesRUDN journal of Sociology, 2017
The author asserts the need for the methodological reflection on the logic and basic approaches to the construction of sociological indices under the growing interest to mathematical modeling in sociology in the nowadays context of information saturation.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Macdonald functions associated to complex reflection groups

open access: yesJournal of Algebra, 2003
Let W be the complex reflection group G(e,1,n). In the author's previous paper, Hall-Littlewood functions associated to W were introduced. In the special case where W is a Weyl group of type B_n, they are closely related to Green polynomials of finite classical groups.

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Green Functions Associated to Complex Reflection Groups

open access: yesJournal of Algebra, 2001
The Green polynomials \(Q_\lambda^\mu(q)\) of \(\text{GL}_n(\mathbb{F}_q)\), where \(\lambda\), \(\mu\) are partitions of \(n\), were first introduced by \textit{J. A. Green} [Trans. Am. Math. Soc. 80, 402-447 (1955; Zbl 0068.25605)] in a combinatorial framework of symmetric functions.
