Soft Open Bases and a Novel Construction of Soft Topologies from Bases for Topologies [PDF]

open access: yesMathematics, 2020
Soft topology studies a structure on the collection of all soft sets on a given set of alternatives (the relevant attributes being fixed). It is directly inspired by the axioms of a topological space.

When ${\rm Min}(G)^{-1}$ has a clopen $øldpi$-base [PDF]

open access: yesMathematica Bohemica, 2021
It is our aim to contribute to the flourishing collection of knowledge centered on the space of minimal prime subgroups of a given lattice-ordered group. Specifically, we are interested in the inverse topology. In general, this space is compact and $T_1$,

An Operational Characterization of Soft Topologies by Crisp Topologies

open access: yesMathematics, 2021
This paper contributes to the expanding literature on soft topology. We first prove that soft topologies can be characterized by crisp topologies. This takes advantage of two connected constructions that produce soft topologies from crisp topologies and ...

New Global Referencing Approach in a Camera-LCD Micro Positioning System

open access: yesSensors, 2020
In any precision manufacturing process, positioning systems play a very important role in achieving a quality product. As a new approach to current systems, camera-LCD positioning systems are a new technology that can provide substantial improvements ...

A true test research of topology identification technology for low voltage distribution networks

open access: yesZhejiang dianli, 2022
Architectural topologies of low voltage distribution networks are hard to “figure out” and “poor in interaction”. Therefore, many topology identification methods have been proposed, most of which have been simulated rather than tested on lines. Thus, low-

Hybrid topologies on the real line

open access: yesApplied General Topology, 2023
Given A ⊆ ℝ , the Hattori space H(A) is the topological space ( ℝ , τA  ) where each a ∈ A has a τA -neighborhood base { ( a − ε , a + ε ) : ε > 0 } and each b ∈ ℝ − A has a τA -neighborhood base { [ b , b + ε ) : ε > 0 } .

Correlation-corrected band topology and topological surface states in iron-based superconductors [PDF]

open access: yes, 2022
Iron-based superconductors offer an ideal platform for studying topological superconductivity and Majorana fermions. In this paper, we carry out a comprehensive study of the band topology and topological surface states of a number of iron-based superconductors using a combination of density functional theory (DFT) and dynamical mean field theory.

Topological Design of a Mortar Base Plate under Impact Loads

open access: yesShock and Vibration, 2021
In this work, the topology optimization of a mortar base plate is analysed under impact loading conditions. Usually, in this case, only ordinary topology optimization under volume constraints is considered.

On the Linear Weak Topology and Dual Pairings over Rings [PDF]

open access: yes, 2004
In this note we study the weak topology on paired modules over a (not necessarily commutative) ground ring. Over QF rings we are able to recover most of the well known properties of this topology in the case of commutative base fields.

Functorial topologies and finite-index subgroups of abelian groups [PDF]

open access: yes, 2011
In the general context of functorial topologies, we prove that in the lattice of all group topologies on an abelian group, the infimum between the Bohr topology and the natural topology is the profinite topology. The profinite topology and its connection
