Modeling and Design of a Novel 5-DOF AC–DC Hybrid Magnetic Bearing

open access: yesApplied Sciences, 2022
This paper investigates a novel integrated AC–DC hybrid magnetic bearing (HMB) to reduce the volume, weight, manufacturing, and operation cost of magnetic suspension motors. Two radial MBs and an axial MB are integrated with the proposed HMB.

Central retinal vascular trunk deviation in unilateral normal-tension glaucoma.

open access: yesPLoS ONE, 2021
PurposeTo investigate whether the position of the central retinal vascular trunk (CRVT), as a surrogate of lamina cribrosa (LC) offset, was associated with the presence of glaucoma in normal-tension glaucoma (NTG) patients.MethodsThe position of the CRVT

The sensitivity of a lower limb model to axial rotation offsets and muscle bounds at the knee [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2012
Soft tissue artifacts during motion capture can lead to errors in kinematics and incorrect estimation of joint angles and segment motion. The aim of this study was to evaluate the effect of shank segment axial rotation and knee rotator muscle bounds on predicted muscle and joint forces in a musculoskeletal model of the lower limb. A maximal height jump

Dynamic Response Analysis of Wedge-Shaped Rock Slopes under Harmonic Wave Action

open access: yesBuildings, 2023
In dynamic disasters involving rock slopes, wedge failures formed by complex structural discontinuities are more predominant, and the dynamic response associated with them remains a classic concern in rock slope engineering. To address this concern, this

A novel axial reluctance resolver proposal and its winding configuration optimization using winding function method

open access: yesEnergy Reports, 2022
The analytical model of a novel axial reluctance resolver based on finite element method and winding function method is proposed in this paper. The developed resolver is composed of a rotor with half-wave magnetic-bands and a stator with parallel teeth ...

Optimal control of axial xenon oscillation in PWR based on on-line data processing of axial offsets.

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1991
In a large pressurized water reactor (PWR), xenon oscillations can occur due to the variation of xenon distribution in the reactor. Horizontal and axial modes of oscillation are known. The former is of less concern because of its convergence but the latter can be divergent.

Design and Experimental Validation of a Ducted Counter-rotating Axial-flow Fans System [PDF]

open access: yes, 2012
An experimental study on the design of counter-rotating axial-flow fans was carried out. The fans were designed using an inverse method. In particular, the system is designed to have a pure axial discharge flow.

Temperature-dependent axial mechanical properties of Zircaloy-4 with various hydrogen amounts and hydride orientations

open access: yesNuclear Engineering and Technology, 2022
The effects of hydride amount (20–850 wppm), orientation (circumferential and radial), and temperature (room temperature, 100 °C, 200 °C) on the axial mechanical properties of Zircaloy-4 cladding were comprehensively examined.
