On Normality in Dense Topological Subspaces

open access: yesInternational Journal of Modern Computation, Information and Communication Technology, 2019
A lot of studies have been conducted on dense topological spaces over a long period of time and interesting results have been obtained. Normality and compactness on topological spaces have also been investigated for decades however, characterization when the subspaces are particularly dense has not been exhausted.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Fault-Tolerant Control and Fault Diagnosis of Symmetrical Six-Phase Permanent Magnet Synchronous Motor Drives without Controller Reconfiguration

open access: yesCES Transactions on Electrical Machines and Systems
Owing to the multi-degree-of-freedom characteristics and inherent fault-tolerant capacity, six-phase motors have been widely adopted in high-power applications, such as electric vehicle propulsion and aerospace systems.

Almost Surjective Epsilon-Isometry in The Reflexive Banach Spaces

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2017
In this paper, we will discuss some applications of almost surjective epsilon-isometry mapping, one of them is in Lorentz space ( L_(p,q)-space). Furthermore, using some classical theorems of w star-topology and concept of closed subspace -complemented ...

Hesitant Fuzzy Topological Spaces

open access: yesMathematics, 2020
In this study, we define a hesitant fuzzy topology and base, obtain some of their properties, respectively, and give some examples. Next, we introduce the concepts of a hesitant fuzzy neighborhood, Q-neighborhood, closure, and interior and obtain some of

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.

Zariski topology on the secondary-like spectrum of a module

open access: yesOpen Mathematics
Let ℜ\Re be a commutative ring with unity and ℑ\Im be a left ℜ\Re -module. We define the secondary-like spectrum of ℑ\Im to be the set of all secondary submodules KK of ℑ\Im such that the annihilator of the socle of KK is the radical of the ...

SUBSPACING BASED ON CONNECTED OPENING SPACES AND FOR DIFFERENT LOCOMOTION TYPES USING GEOMETRIC AND GRAPH BASED REPRESENTATION IN MULTILAYERED SPACE-EVENT MODEL (MLSEM) [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Indoor navigation has to deal with more issues as compared to outdoor navigation. Those issues include but are not limited to; need more level of detail to process enclosing area around navigating subject or object, consideration of the context of ...

Topologies generated by discrete subspaces

open access: yesGlasnik matematički, 2002
A topological space \(X\) is called discretely generated if for every \(A\subset X\) the closure of \(A\) is the union of the closures of discrete subspaces of \(A\), and \(X\) is a weakly discretely generated space if for every \(A\subset X\) with \(\overline{A}\neq A\) there exists a discrete subset \(D\) of \(A\) such that \(\overline{D ...
