Abstract: This study presents an inductive power transfer (IPT) system for electric vehicles (EVs) based on EE-shaped ferrite cores. The issues of the IPT system such as efficiency, air gap, displacement, dislocation, and motion are discussed. Furthermore, finite element analysis software is utilized to simulate the IPT system operated under large air gap conditions. Simulation and measurement ...

Variable reactors have been a vital component of power networks for decades, where they used as fault-current limiting devices or reactive compensation. Traditionally, modifying the inductance predominantly mechanically operated variable requires seconds to minutes. In contrast, virtual air gap (VAG) can change within milliseconds, potentially improving system stability. Existing dynamic models...

Zinc Sulfide (ZnS) thin films were deposited on glass substrates at the pressure of 10-6 mbar by thermal resistor evaporation technique. The effects of annealing on the structural, optical properties of ZnS films were studied. Crystalline ZnS films have been analyzed by X-ray diffraction. Only cubic phase with the preferred (111) plane was found in ZnS films. Optical characteristics were studie...

The characteristics of acoustic wave transmitting in a metamaterial-type seawater piping system are studied. The metamaterial pipe, which consists of a uniform pipe with air-water chamber Helmholtz resonators (HRs) mounted periodically along its axial direction, could generate a wide band gap in the low-frequency range, rendering the propagation of low-frequency acoustic waves in the piping sys...

Raman spectra of ordered carbon nanomaterials are quite sensitive to surface perturbations, including trace residues, structural defects and residual stress. This is demonstrated by a series of experiments with carbon nanotubes and graphene. Their spectra change due to subtle changes in preparation and attachment to the substrate and to each other. Differences are most clearly seen by forming a...

OBJECTIVES This study aims to report early postoperative complications and hearing results in patients with chronic otitis media undergoing endoscopic transcanal tympanoplasty. PATIENTS AND METHODS Twenty-four patients (6 males, 18 females; mean age 25.9 years; range 9 to 46 years) who were operated with endoscopic transcanal tympanoplasty in the Department of Otorhinolaryngology, Faculty of ...
