This study investigates the statistic behavior and parameter estimation problems of a double-sided, LCC-compensated, wireless power transfer system. Based on commonly used charging circuit model, this proposes five-step method, which is applicable to automotive static systems. The eight parameters in model are most important key components also found that, under certain conditions, mode systems...

Introduction: In previous work, we introduced the concept of the multimode coil [1]. The multimode coil consists of a tracking coil connected in series with a multi-turn imaging coil and simultaneously performs the functions of active tip tracking, imaging and inductively coupled wireless marker. The tracking and imaging coils have conflicting design requirements. While the region of sensitivit...

In this study, the design, numerical modelling, and construction of various Helmholtz pair coil systems were investigated to produce a homogeneous magnetic field. The field was simulated using three different including 2-coil, 3-coil, 4-coil combinations in order optimize homogeneity strength over region interest that consists cylindrical geometry with height 700 mm diameter 90 mm. created by s...

The Levitated Dipole Experiment (LDX) is an innovative approach to explore the magnetic confinement of a fusion plasma offering the possibility of an improved fusion power source. In this concept, a magnetic dipole (a superconducting solenoid) is magnetically levitated for several hours at the center of a 5 m diameter, 3 m tall vacuum chamber. The Floating coil (F-coil) is designed for a maximu...

Here we investigate the utility of a dual-echo Echo-Planar Imaging (DE-EPI) Diffusion Weighted Imaging (DWI) approach to improve lesion conspicuity in pediatric imaging. This method delivers two 'echo images' for one diffusion-preparation period. We also demonstrate how the echoes can be utilized to remove transmit/receive coil-induced and static magnetic field intensity modulations on both ech...

Using a nearly monodisperse high molar mass poly(N-isopropylacrylamide) (PNIPAM) sample, we successfully made the conformation change of individual PNIPAM chains from a coil to a fully collapsed stable single chain globule in an extremely dilute aqueous solution, which enabled us to study for the first time the globule-to-coil transition of a single homopolymer chain in solution. A comparison t...

BACKGROUND AND PURPOSE Coil migration is a potentially serious complication of endovascular aneurysm treatment. The aim of the study was to systematically investigate the effectiveness of coil retrieval with a stent retriever in an animal model. MATERIALS AND METHODS A total of 148 coils of various types and sizes were placed into arteries of varying diameters in a porcine in vivo model. Coil...

Carbon fiber reinforced polymer materials (CFRP) cause CFRP to bend or fail when subjected external loads impacts. In the case of static three-point bending, using conductive properties carbon inside CFRP, overall damage detection and failure prediction can be carried out by electromagnetic methods. The eddy current coil is used realize real-time monitoring damage, measured voltage value mapped...

OBJECTIVE To compare two commonly used TMS coils, namely the Medtronic MC-B70 double coil and the Magstim 70 mm double coil, with respect to their electric field distributions induced on the cortex. METHODS Electric field properties are calculated on a hemisphere representing the cortex using a spherical head model. The coil designs are characterised using several parameters, such as focality...
