Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Emotional Faces in Symbolic Relations: A Happiness Superiority Effect Involving the Equivalence Paradigm

Frontiers in Psychology, 2019
The stimulus equivalence paradigm presented operational criteria to identify symbolic functions in observable behaviors. When humans match dissimilar stimuli (e.g., words to pictures), equivalence relations between those stimuli are likely to be ...

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 ...

Equivalence – Equivalence Relations: Effects of Training-Structure and Competition Between Arbitrary and Relations of Physical Similarity

Revista Argentina de Ciencias del Comportamiento, 2011
In this paper we study the necessary and sufficient conditions for the training of conditional relations, the formation of equivalence classes and relations of "equivalence - equivalence".

Closed equivalence relations on compact spaces and pairs of commutative C*-algebras: a Categorical Approach

Visnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika
In this paper, we study a categorical extension of the classical Gelfand-Naimark duality between compact Hausdorff spaces and commutative unital C*-algebras.

On families of twisted power partial isometries

Karpatsʹkì Matematičnì Publìkacìï, 2022
We consider families of power partial isometries satisfying twisted commutation relations with deformation parameters $\lambda_{ij}\in\mathbb C$, $|\lambda_{ij}|=1$.

von Neumann’s problem and extensions of non-amenable equivalence relations [PDF]

Groups, Geometry, and Dynamics, 2015
The goals of this paper are twofold. First, we generalize the result of Gaboriau and Lyons [GL07] to the setting of von Neumann's problem for equivalence relations, proving that for any non-amenable ergodic probability measure preserving (pmp ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

On Magnifying Elements in E-Preserving Partial Transformation Semigroups

Mathematics, 2018
Let S be a semigroup. An element a of S is called a right [left] magnifying element if there exists a proper subset M of S satisfying S = M a [ S = a M ] . Let E be an equivalence relation on a nonempty set X.

FUZZY GROUPOIDS VERSUS LEFT INVARIANT FUZZY EQUIVALENCE RELATIONS [PDF]

Fiabilitate şi Durabilitate, 2023
The purpose of this note is to highlight the relationship between T-fuzzy groupoids and left (or right) invariant T-fuzzy equivalence relations. We will also show that there is a 1 - 1 correspondence between the T-fuzzy reductions of a T-fuzzy groupoid
