AlGaN/GaN HFET’s have been analyzed under DC and RF Stimulus in an attempt to analyze the phenomenon of DC-RF dispersion. DC pulsed I-V measurements were performed where the pulse “off” state was set to different bias points, to simulate a class A bias condition at various drain voltages. RF timedomain waveform measurements were also performed. The I-V measurements exhibited the common problem ...

In current Doppler blood flow studies, the low Doppler shift frequencies of high energy generated by the wall motion are purposely filtered out. Since these low Doppler shift frequencies are produced by the contracting myocardium, they are expected to contain potential information for the assessment of myocardial properties. Early descriptions of directional pulsed Doppler tissue imaging (DTI) ...

The next generation of US Navy ships will employ high energy pulsed power weapons and sensor systems. The electrical power systems on current Navy surface ships are not capable of directly supplying instantaneous generation demand of the magnitude that these high energy loads require. As a result, there is a need for an open architecture concept for systems integration including an energy stora...

the purpose of the present study was to explore the passive and electrically assisted transdermal transport of granisetron hydrochloride (gra) in solution and gel formulation through iontophoresis and also the feasibility of delivering therapeutic amounts of drug for the treatment of chemotherapy-induced nausea and vomiting. in this study, iontophoretic permeation of gra through guinea pig skin...

Abstract This paper introduces a stochastic model of battery behavior, that emulates electrochemical mechanisms that are key to battery performance under pulsed discharge conditions. A pulsed discharge allows charge recovery during the idle periods. Recovery depends on the state of charge of the battery and on the duration of the rest time period. Using the postulated model, we derive the impro...

This proposal concerns component development for a novel hybrid lidar-radar system for underwater surveillance. Computer simulations and laboratory measurements of pulsed lidar revealed a 17 dB suppression of the water backscatter signal (clutter) and corresponding target contrast enhancement. Preliminary ocean experiments have confirmed the potential of pulsed lidar to be a superior detection ...

Although lithium metal is an ideal anode material for achieving high-energy-density lithium-based batteries, the uneven deposition/exfoliation process of during cycling easily triggers formation dendrites and dead lithium, which leads to a low Coulombic efficiency safety issues. In this paper, lithiophilic 3D copper mesh current collector designed by using ZnO pulsed plating applied battery com...
