Fixed Points of Asymptotic Pointwise Nonexpansive Mappings in Modular Spaces

Journal of Applied Mathematics, 2012
Kirk and Xu studied the existence of fixed points of asymptotic pointwise nonexpansive mappings in the Banach space. In this paper, we investigate these kinds of mappings in modular spaces.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Fixed point theorem and iterated function system in φ-metric modular space

Fixed Point Theory and Algorithms for Sciences and Engineering
We introduce and study the concept of φ-metric modular space and, then define φ-α-Meir-Keeler contraction on it and explore its fixed point. Further, we define the Hausdorff distance between two non-empty compact subsets of the considered space.

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, EarlyView.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Rigid and soft modularity: the case of a Beiruti shoreline

Vitruvio: International Journal of Architectural Technology and Sustainability
This paper explores spatial systems of modularity on the shoreline of Ein el Mrayseh located in Beirut. The modular systems are studied from a contextual lens while observing different modular interventions as design strategies on this shoreline. The Ein

Modular multifunctional space

, 2022
[EN] The objective of the project is to re-use an existing historical building towards sustainable multifuncional spaces making it suitable for all sorts of events by modular design or modularity in design. This is a design principle that subdivides a system into smaller parts called modules, which can be independently created, modified, replaced, or ...

THE MODULAR SPACES OF MULTIFUNCTIONS, II

Demonstratio Mathematica, 1990
In this paper we introduce the spaces of multifunctions \(X_ \varphi\) and \(X^ n_ \varphi\), where \(n\) is a natural number and \(\varphi\) is a \(\varphi\)-function. We also introduce the functions \(m(F)\), \(\underline {f}(F)\) and \(\overline {f}(F)\).

Equimodular and linearity in modular spaces

Journal of Mathematical Analysis and Applications, 2003
Let \(X_\rho\) and \(Y_\rho\) be two modular spaces generated by modulars \(\rho_X\) and \(\rho_Y\), respectively. The authors consider the question when \(\rho\) is an inverting modular for the norm (\(F\)-norm) in \(X\), and the problem of sufficient conditions in order that a mapping \(T: X_\rho\to Y_\rho\) be affine.

A Concept of a Digital and Traceable Manufacturing Documentation Based on Formalized Process Description Applied on Composite Aircraft Moveable

Advanced Engineering Materials, EarlyView.
The documentation of component manufacture has become an essential part of today's production processes, especially for the analysis and optimization of production or component design with regard to structural performance, economic efficiency, and sustainability.
