Completely regular and 𝜔-regular spaces

open access: yes, 1981
The completely regular convergence spaces are characterized as those spaces having symmetric compactifications. The ω \omega -regular convergence spaces are those which have regular compactifications.

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

open access: yesAdvanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

NOMINAL CONVERGENCE: THE CASE OF ROMANIA [PDF]

open access: yes
The main objectives of this paper are: determining the extent to which the indicators of nominal convergence reflect the reality of the Romanian economy, in order to find an optimal correlation between nominal and real convergence from the point of view ...

Order convergence of vector measures on topological spaces [PDF]

open access: yes, 2005
summary:Let $X$ be a completely regular Hausdorff space, $E$ a boundedly complete vector lattice, $C_{b}(X)$ the space of all, bounded, real-valued continuous functions on $X$, $\mathcal{F}$ the algebra generated by the zero-sets of $X$, and $\mu \: C_{b}

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Strong convergence theorem for amenable semigroups of nonexpansive mappings and variational inequalities

open access: yesFixed Point Theory and Applications, 2011
In this paper, using strongly monotone and lipschitzian operator, we introduce a general iterative process for finding a common fixed point of a semigroup of nonexpansive mappings, with respect to strongly left regular sequence of means defined on an ...

Market-Driven Management, Global Markets and Competitive Convergence [PDF]

open access: yes
Global markets redefine competition space, fostering a collaborative network between companies (market-driven management). Globalisation it causes previously distinct global economies to converge into a single large market, thus generating fusion between

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

open access: yesAdvanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

REGULAR CONVERGENCE AND FINITE ELEMENT METHODS FOR EIGENVALUE PROBLEMS

open access: yes, 2023
Regular convergence, together with other types of convergence, have been studied since the 1970s for discrete approximations of linear operators. In this paper, we consider the eigenvalue approximation of a compact operator T that can be written as an ...
