Magnetic vortex lattices in finite isospin chiral perturbation theory

open access: yesPhysics Letters B, 2019
We study finite isospin chiral perturbation theory (χPT) in a uniform external magnetic field and find the condensation energy of magnetic vortex lattices using the method of successive approximations (originally used by Abrikosov) near the upper ...

On Uniformly Generalized Lipschitzian Mappings

open access: yesFixed Point Theory and Applications, 2010
We consider another class of generalized Lipschitzian type mappings and utilize the same to prove fixed point theorems for asymptotically regular and uniformly generalized Lipschitzian one-parameter semigroups of self-mappings defined on bounded metric ...

High accurate analysis by experiment and simulation using Bayesian inference for corrugated cardboard

open access: yesMechanical Engineering Journal, 2016
Corrugated cardboards are used in many fields. The design of corrugated cardboard, however, is based on experimentations. The subject of this paper is developing the technique for high accurate analysis of corrugated cardboards.

Preparation of foam ceramics from solid wastes: a study on the relationship between firing regime and properties by grey system theory

open access: yesJournal of Materials Research and Technology, 2023
Foam ceramics were prepared by using 80 wt.% sand shale, 8 wt.% coal fly ash, 8 wt.% steel slag and 4 wt.% magnesite as raw materials and 0.3 wt.% SiC as foam agent.

MHD flow of Burger’s fluid over an off-centered rotating disk in a porous medium

open access: yesAIP Advances, 2015
In this study, off-centered stagnation flow of three dimensional Burger’s fluid over an infinite rotating disk in a porous medium with a uniform magnetic field, which is applying normal to the disk, is investigated. A uniform suction/injection is applied

The influence of structure uniformity on resonant frequency of ultra-high frequency radio frequency identification tag thread With normal mode helix dipole antenna

open access: yesJournal of Industrial Textiles, 2022
The stable performance of ultra-high frequency radio frequency identification (UHF RFID) tag thread with normal mode helical dipole antenna (NMHDA) was required for industrialized application. The ununiform helical pitches and helical radiuses caused by the unstable tension in the preparation process and material properties of carrying yarn probably ...

Common fixed point theorems for commuting k-uniformly Lipschitzian mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We give a common fixed point existence theorem for any sequence of commuting k-uniformly Lipschitzian mappings (eventually, for k=1 for any sequence of commuting nonexpansive mappings) defined on a bounded and complete metric space (X,d) with uniform ...

Metamaterials mapped lightweight structures by principal stress lines and topology optimization: Methodology, additive manufacturing, ductile failure and tests

open access: yesMaterials & Design, 2021
In lightweight engineering, mechanical metamaterials (MMs) are suitable for additive manufacturing (AM) due to their geometry complexity. However, it is inevitable to bring about mechanical deviation and local yield for MMs infilled lightweight ...
