A Nonparametric Dual Control Algorithm of Multidimensional Objects with Interval-Valued Observations

open access: yesAxioms, 2023
We focus on the dual interval control problem of multidimensional objects with delay. We propose a new nonparametric algorithm. In such a case, it is not necessary to determine a parametric structure of the investigated object. Another difficulty lies in

Finiteness properties of cubulated groups

open access: yes, 2014
We give a generalized and self-contained account of Haglund-Paulin's wallspaces and Sageev's construction of the CAT(0) cube complex dual to a wallspace. We examine criteria on a wallspace leading to finiteness properties of its dual cube complex.

Characterization of topological states via dual multipartite entanglement

open access: yes, 2018
We demonstrate that multipartite entanglement is able to characterize one-dimensional symmetry-protected topological order, which is witnessed by the scaling behavior of the quantum Fisher information of the ground state with respect to the spin ...

Dual convection of NEPCM inside an annulus between two circular cylinders mounted on rectangles

open access: yesAlexandria Engineering Journal, 2023
This paper adopts the incompressible smoothed particle hydrodynamics (ISPH) method for simulating the dual diffusion of nano-encapsulated phase change material (NEPCM) in an annulus.

A Broad Class of Discrete-Time Hypercomplex-Valued Hopfield Neural Networks

open access: yes, 2019
In this paper, we address the stability of a broad class of discrete-time hypercomplex-valued Hopfield-type neural networks. To ensure the neural networks belonging to this class always settle down at a stationary state, we introduce novel hypercomplex ...

The v-numbers of Stanley–Reisner ideals from the viewpoint of Alexander dual complexes

open access: yesJournal of Algebra
We express the v-number of the Stanley-Reisner ideal in terms of its Alexander dual complex and prove that the v-number of a cover ideal is just two less than the initial degree of the its syzygy module. We give some relation between the v-number of the Stanley-Reisner ideal and the Serre-depth of the quotient ring of the second symbolic power of the ...

Dual XH–π Interaction of Hexafluoroisopropanol with Arenes

open access: yesMolecules, 2021
The dual XH (OH and CH) hydrogen-bond-donating property of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) and the strong dual XH–π interaction with arenes were firstly disclosed by theoretical studies. Here, the high accuracy post-Hartree–Fock methods, CCSD(T)/

On a New Generalization of Pell Hybrid Numbers

open access: yesAnnales Mathematicae Silesianae
In this paper, we define and study a new one-parameter generalization of the Pell hybrid numbers. Based on the definition of r-Pell numbers, we define the r-Pell hybrid numbers.

Investigating the Short-Circuit Problem Using the Planarity Index of Complex q-Rung Orthopair Fuzzy Planar Graphs

open access: yesComplexity, 2021
Planar graphs play an effective role in many practical applications where the crossing of edges becomes problematic. This paper aims to investigate the complex q-rung orthopair fuzzy (CQROF) planar graphs (CQROFPGs). In a CQROFPG, the nodes and edges are
