متن کاملComparative Analysis of Small Signal and Large Signal parameters in Heterostructure Field Effect Transistors
Heterostructure field effect transistors (HFETs) are based on AlGaN/GaN heterostructures which offer excellent electronic properties for the development of faster, heat-resistant , energy efficient transistors and application in microwave-power amplifiers [1,2]. The outstanding device performance in cut-off frequency, breakdown voltage, and device output power [3,4]. However, the comparatively ...
متن کاملKinetics analysis of electrophoretic deposition using small signal and large signal modeling, Case study: Nano-Mullite suspension
Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...
متن کاملOptical Emissions from Proton Aurora
Hydrogen emissions are the signature of proton aurora. The Doppler-shifted hydrogen emission lines can be interpreted in terms of the mean energy of the precipitating protons. A red shifted component of the line profiles observed from the ground indicates upward going hydrogen atoms due to angular redistribution of the precipitation. Secondary electrons from ionization and stripping collisions ...
متن کاملVibrotactile Detection, Identification and Directional Perception of signal-Processed Sounds from Environmental Events: A Pilot Field Evaluation in Five Cases
Objectives: Conducting field tests of a vibrotactile aid for deaf/deafblind persons for detection, identification and directional perception of environmental sounds. Methods: Five deaf (3F/2M, 22–36 years) individuals tested the aid separately in a home environment (kitchen) and in a traffic environment. Their eyes were blindfolded and they wore a headband and holding a vibrator for sound id...
