Optimization of the Shape of an Electromagnet: Regularity

In this paper we study the regularity of the solution of an elliptic partial di erential equation with discontinuous coe cients. This result is used to establish the continuous Fr echet di erentiability of a shape functional arising in the optimal shape design of an electromagnet.

Modeling, Simulation and Control of Dual Electromagnet Active Magnetic Levitation

This paper presents the simulation of the dual electromagnet Active Magnetic Levitation System realized in the COMSOL Multiphysics software. The mixed mode of Partial Differential and Ordinary Differential Equations is used to realize the levitated object motion. Two control scenarios are given as illustrative example of the working model.

A computer-based recursion algorithm for automatic charge of power device of electric vehicles carrying electromagnet

This paper proposes a computer-based recursion algorithm for automatic charge of power device of electric vehicles carrying electromagnet. The charging system includes charging cable with one end connecting gang socket, electromagnetic gear driving the connecting socket and a charging pile breaking or closing, and detecting part for detecting electric vehicle static call or start state. The gan...

Handheld electromagnet carrier for transfer of hyperpolarized carbon-13 samples.

PURPOSE Hyperpolarization of carbon-13 ((13) C) nuclei by dissolution dynamic nuclear polarization increases signal-to-noise ratio (SNR) by >10,000-fold for metabolic imaging, but care must be taken when transferring hyperpolarized (HP) samples from polarizer to MR scanner. Some (13) C substrates relax rapidly in low ambient magnetic fields. A handheld electromagnet carrier was designed and con...
