At present, gyrotron oscillators, as sources of high power millimeter waves, play a central role in fusion energy research. Recently, spurious oscillations in high power gyrotrons gained attention as an influencing factor on the overall efficiency: in the up-taper/launcher section, a region exists where the decreasing magnetic field is alleged to excite spurious oscillations1. Numerical investigations...
A phenomenological mathematical model for predicting FFA-glucose-insulin dynamics during rest and exercise was developed. The dynamical effects of insulin on glucose and FFA were divided into three parts: (i) insulin-mediated glucose uptake by tissues, (ii) insulin-mediated suppression of endogenous glucose production, and (iii) anti-lipolytic effects of insulin. Labeled and unlabeled intravenous...
Current technology allows steganography applications to conceal any digital file inside of another digital file. Due to the large number of steganography tools available over the Internet, a particular threat exists when criminals use steganography to conceal their activities within digital images in cyber space. In this paper, a set of statistical features are generated using linear mixed effects...
In this paper, a generalized design methodology for operational transconductance amplifier (OTA) based current mode radio frequency (RF) communication circuit is proposed. Three novel communication circuits, phase lock loop (PLL), adaptive delta modulator (ADM) and data compressor have been simulated. In the first implementation, direct frequency modulation is used to realize PLL, while the second...
