Simulation of the Electro-Superconducting System Based on the H Equation

open access: yesJournal of Chemistry, 2022
In order to reduce the levitation energy consumption and increase the levitation air gap, a simulation study of the electrochemistry superconducting magnetic levitation system based on the H equation is proposed.

Magnetic Levitation in Chemistry, Materials Science, and Biochemistry.

open access: yesAngewandte Chemie, 2020
All matter has density. The uses of density to characterize matter date back as early as ~250 BC when Archimedes was believed to have solved "The Puzzle of The King's Crown". Today, measurements of density are used to separate and characterize a range of

Theoretical analysis and experimental validation of a simplified fractional order controller for a magnetic levitation system [PDF]

open access: yes, 2015
Fractional order (FO) controllers are among the emerging solutions for increasing closed-loop performance and robustness. However, they have been applied mostly to stable processes.

Magnetic Levitation Belt Conveyor Control System Based on Multi-Sensor Fusion

open access: yesApplied Sciences, 2023
Belt conveyors are critical in coal transportation systems; however, they are supported by rollers, which incur high energy costs. Magnetic levitation support is adopted.

Spatial interference from well-separated condensates [PDF]

open access: yes, 2010
We use magnetic levitation and a variable-separation dual optical plug to obtain clear spatial interference between two condensates axially separated by up to 0.25 mm -- the largest separation observed with this kind of interferometer.

Magnetic field is the dominant factor to induce the response of Streptomyces avermitilis in altered gravity simulated by diamagnetic levitation. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Diamagnetic levitation is a technique that uses a strong, spatially varying magnetic field to simulate an altered gravity environment, as in space.

Ground Effects and Stability Analysis of Airfoil Accelerated by Electromagnetic Propulsion

open access: yes气体物理
Aerospace vehicle launched by electromagnetic propulsion is a potential option for future reusable space transportation systems. Complex ground effects and stability issues are induced generally due to the introduction of electromagnetic levitation force.

Dependence of Levitation Force on Frequency of an Oscillating Magnetic Levitation Field in a Bulk YBCO Superconductor

open access: yes, 2012
The dependence of the magnetic field strength required for levitation of a melt textured, single domain YBCO superconductor disc on the frequency of the current generating the levitating magnetic field has been investigated.
