Recent implementations of binaural synthesis have combined high-frequency pinna diffraction data with low-frequency acoustic models of the head and torso. This combination ensures that the salient cues required for directional localization in the horizontal plane are consistent with psychophysical expectations, regardless of the accuracy or match of the high-frequency cues, or the fidelity of e...

When using bone vibrator transducers for clinical measurements, the transfer of energy from the bone driver depends on the impedance match between the driver and the load (human mastoid or otherwise) to which the driver will be applied. Current clinical calibration methods are incapable of quantifying this impedance mismatch, hence they fail to account for inter-subject variations of the energy...

This paper proposes a model of coupled inductor which takes into account the influence frequency, temperature, and constant component, IDC, currents in windings on parameters considered element. A description methods measuring using an impedance analyzer chamber for thermal measurements is given. The obtained results are compared with calculations proving satisfactory match.

The signal integrity of the circuit, as one of the important design issues in high-speed digital system, is usually seriously affected by the signal reflection due to impedance mismatch in the DDR3 bus. In this paper, a novel optimization method is proposed to optimize impedance mismatch and reduce the signal reflection. Specifically, by applying the via parasitic, an equivalent model of DDR3 h...

The effects of exercise on the pulmonary circulation were studied in seven experiments on five dogs. Pulsatile pulmonary arterial flow and pressure and left atrial pressure were measured by chronically implanted transducers; pulmonary vascular input impedance, resistance, and hydraulic power were computed. The average effects of running on a treadmill at 6.5 mph, as compared with the resting st...

In this paper; we propose a method for generating realistic shadows of virtual objects inserted into a real video sequence. Our aim is to improve and extend the work of [ I ] , which is based on a static camera, to the case of a video sequence. This extension consists of several procedures: calibration of a moving video camera and a graphic camera, removing false shadows occurring due to a shor...

With the virtual enforcement of the required boundary condition (BC) at the end of a slot antenna, the area occupied by the resonant antenna can be reduced. To achieve the required virtual BC, the two short circuits at the end of the resonant slot are replaced by some reactive BC, including inductive or capacitive loadings. The application of these loads is shown to reduce the size of the reson...

We have developed an RF accelerating system for a compact ion synchrotron. The RF cavity is an untuned type loaded with FINEMET cores, which have high complex permeability, high saturation flux density, and high Curie temperature properties. A new power feeding method, “multi-feed coupling,” was developed to match the cavity impedance with output impedance of a solidstate RF amplifier. We have ...

Rf power at 2856 MHz has been obtained from the SLAC proof of principle lasertron. Experiments show that the electron beam is well bunched when the laser beam is well dispersed, the voltage high, and the current density low. However, if any of the these criteria is not met, space charge forces can cause significant debunching. The maximum beam power to rf power conversion efficiency was 12.3%, ...

In this paper, a dual-band dipole antenna for passive radio frequency identification (RFID) tag application at 2.45 GHz and 5.8 GHz is designed and optimized using HFSS 13. The proposed antenna is composed of a bent microstrip patch and a coupled rectangular microstrip patch. The optimal results of this antenna are obtained by sweeping antenna parameters. Its return losses reach to −18.7732 dB ...
