Purpose: In this work, a finite element study is proposed to evaluate the effects of the transducer and its coupling layer on the performance of round window (RW) stimulation. Methods: Based on a set of micro-computer tomography images of a healthy adult’s right ear and reverse engineering technique, a coupled finite-element model of the human ear and the transducer was constructed and verified. Then,...
The paper presents the investigation of the electromagnetic interference for the traction system in a high speed railway (HSR). Tt is important to study the characteristic of the transformer, converter and power cable for HSR. Traction transformer as the one of the first equipment on board traction system for connection to pantograph, and plays a key role in the electromagnetic investigation. In this...
Axial field flux-switching permanent magnet machine (AFFSPMM) is a novel permanent magnet (PM) machine which incorporates the merits of flux-switching PM (FSPM) machine and axial field PM machine. AFFSPMM exhibits many advantages, such as sinusoidal back-EMF waveform, good flux weakening capability, favorable for cooling, high torque/power density and high efficiency [1]. However, compared to the...
With the increasing market demand on mobile phone, demand on microspeakers with lower flux leakage has been rising rapidly. As is shown in Fig.1 (a), caused by flux leakage, especially by the maximum flux leakage (BLmax) in the side of sound holes, the dust accumulation through sound holes has a harmful impact on the performance of a microspeaker. Nowadays, a lower grade magnet or a smaller magnet...
The speed of shear wave propagation in tissue is directly related to the tissue's shear modulus. Shear waves can be generated in tissue using focused, impulsive, acoustic radiation force excitations. Shear modulus reconstruction has typically been performed by monitoring shear wave propagation in regions that are spatially offset from the region of excitation (ROE), but such methods require greater...
