Using novel simplified models of excitation for analytic description of initiation propagation and blockage of excitation waves [PDF]

open access: yes, 2006
We consider applications of a recently suggested new asymptotic approach to detailed ionic models of cardiac excitation. First, we describe a three-variable approximation for the excitation fronts in a detailed ionic model of human atrial kinetics.

Influence of the Excitation Wavelength on First Order Hyperpolarizabilities and Optimal Gap Tuning of Range Separated Hybrid Functionals [PDF]

open access: yes, 2022
In this study, we compute the hyperpolarizability of the nitroaniline isomers, para-nitroaniline (pNA), ortho-nitroaniline (oNA), and meta-nitroaniline (mNA), by density functional theory (DFT), including with optimally tuned range separated hybrid (RSH)

Performance Evaluation of an Axial Flux Machine with a Hybrid Excitation Design

open access: yesEnergies, 2022
Variable speed, permanent magnet synchronous machines with hybrid excitation have attracted much attention due to their flux-control potential. In this paper, a design of permanent magnet axial flux machines with iron poles in the rotor and an additional

Overview of Degrees of Freedom in the Design of PM Synchronous Machines

open access: yesEnergies, 2021
This contribution discusses the degrees of freedom that could be advantageously exploited in the conception of permanent magnet (PM) machines in the context of very demanding applications, such as electrical vehicle traction.

Orbital-hybridization-created optical excitations in Li2GeO3 [PDF]

open access: yesScientific Reports, 2021
AbstractThe three-dimensional ternary Li2GeO3 compound presents various unusual essential properties. The main features are thoroughly explored from the first-principles calculations. The concise pictures, the critical orbital hybridizations in Li–O and Ge–O bonds, are clearly examined through the optimal geometric structure, the atom-dominated ...

Comparative Investigation of Hybrid Excitation Flux Switching Machines

open access: yesEnergies, 2018
In this paper, the effect of partitioned stator (PS) structure and iron flux bridges in hybrid excitation flux switching (HEFS) machines is comprehensively discussed and compared. Firstly, the operating principles of four HEFS machines with single stator

Design and Characteristic Analysis of a New Dual-Stator Bearingless Switched Reluctance Motor

open access: yesIEEE Access, 2022
This paper proposes a 18/15/6 pole dual-stator bearingless switched reluctance motor (DSBSRM) with better overall performance. The proposed motor separates the torque control system and the suspension control system with a magnetic isolation ring.
