Abstract and Applied Analysis, 2015 Let C={Cα}α∈A∈[1;∞)A, A-index set. A quasi-triangular space (X,PC;A) is a set X with family PC;A={pα:X2→[0,∞), α∈A} satisfying ∀α∈A ∀u,v,w∈X {pα(u,w)≤Cα[pα(u,v)+pα(v,w)]}.

Set-open topologies on function spaces
Applied General Topology, 2018 Let X and Y be topological spaces, F(X,Y) the set of all functions from X into Y and C(X,Y) the set of all continuous functions in F(X,Y). We study various set-open topologies tλ (λ ⊆ P(X)) on F(X,Y) and consider their existence, comparison and ...

Some Invariant Properties of Quasi-Möbius Maps
Analysis and Geometry in Metric Spaces, 2017 We investigate properties which remain invariant under the action of quasi-Möbius maps of quasimetric spaces. A metric space is called doubling with constant D if every ball of finite radius can be covered by at most D balls of half the radius.

Duality and quasi-normability for complexity spaces
Applied General Topology, 2002 The complexity (quasi-metric) space was introduced in [23] to study complexity analysis of programs. Recently, it was introduced in [22] the dual complexity (quasi-metric) space, as a subspace of the function space [0,) ω. Several quasi-metric properties

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Order compatibility for Cauchy spaces and convergence spaces
International Journal of Mathematics and Mathematical Sciences, 1987 A Cauchy structure and a preorder on the same set are said to be compatible if both arise from the same quasi-uniform convergence structure on X. Howover, there are two natural ways to derive the former structures from the latter, leading to strong and

Relations between generalized von Neumann-Jordan and James constants for quasi-Banach spaces
Journal of Inequalities and Applications, 2016 Let C N J ( B ) $\mathcal{C}_{NJ} ( \mathcal{B} )$ and J ( B ) $J ( \mathcal{B} )$ be the generalized von Neumann-Jordan and James constants of a quasi-Banach space B $\mathcal{B}$ , respectively.

Additive Manufacturing of Alumina‐Reinforced Elastomers
Advanced Engineering Materials, EarlyView.Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

A topological space without a complete quasi-uniformity [PDF]
Proceedings of the American Mathematical Society, 1984 We show that an example of Burke and van Douwen has no complete quasi-uniformity. Moreover, we show that it is almost finitely-fully normal but not almost
