Design and Experimental Investigations of Shape and Attitude Carding System for the Wires of Micro Coreless Motor Winding

open access: yesMicromachines, 2021
The shape and attitude (S&A) of the electrode wire are important characteristics of micro coreless motor winding. The purpose of this paper is to present the design of a robotic micro-manipulation system for micro wire carding with arbitrary S&A, which ...

Lattice study of area law for double-winding Wilson loops

open access: yes, 2017
We study the double-winding Wilson loops in the SU(N) Yang-Mills theory on the lattice. We discuss how the area law falloff of the double-winding Wilson loop average is modified by changing the enclosing contours C1 and C2 for various values of the ...

U-duality transformation of membrane on $T^{n}$ revisited [PDF]

open access: yes, 2016
The problem with the U-duality transformation of membrane on $T^{n}$ is recently addressed in [arXiv:1509.02915 [hep-th]]. We will consider the U-duality transformation rule of membrane on $T^{n}\times R$.

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Modelling axial vibration in windings of power transformers

open access: yesOpen Physics, 2017
This paper describes the method of homogenization of material properties applied to windings used in power transformers. Exemplary results of natural modes of vibrations obtained by means of finite elements method are also included.

Improving the main indicators of transformers with twisted one-piece magnetic cores by changing the technology of circular winding turns formation

open access: yesElectrical engineering & Electromechanics, 2022
Introduction. With the adoption of standards to reduce losses in transformers it is necessary to change the design of transformers that remain unchanged.

Phase Winding a Two-Component BEC in an Elongated Trap: Experimental Observation of Moving Magnetic Orders and Dark-bright Solitons

open access: yes, 2013
We experimentally investigate the phase winding dynamics of a harmonically trapped two-component BEC subject to microwave induced Rabi oscillations between two pseudospin components.

Dynamical signatures of topological order in the driven-dissipative Kitaev chain [PDF]

open access: yes, 2019
We investigate the effects of dissipation and driving on topological order in superconducting nanowires. Rather than studying the non-equilibrium steady state, we propose a method to classify and detect dynamical signatures of topological order in open ...

Galactic Winds [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
In the sequel we will be discussing that - apart from all other halo flows - it is highly probable that our Galaxy has a systematic mass loss; most other galaxies should behave in a similar way. This mass loss should occur in the form of a supersonic galactic wind provided the intergalactic pressure is low enough.

Classifying Transformer Winding Deformation Fault Types and Degrees Using FRA Based on Support Vector Machine

open access: yesIEEE Access, 2019
As an important part of power system, power transformer plays an irreplaceable role in the process of power transmission. Diagnosis of transformer’s failure is of significance to maintain its safe and stable operation.
