INTRODUCTION Exposure to the confined hyperbaric, hyperoxic environment of the saturation chamber poses a number of unique physiological challenges to divers. Appropriately tailored training, nutrition and health programs may help support the body to cope with and overcome these challenges. AIM To describe the self-reported habits and attitudes of(More)
The conflict between humans and elephants has been reported as a serious socioeconomic problem in various regions in India and across the world. The cause, effects and reduction of such conflict, are a rapidly expanding areas of research across the world among the conservationists, scientists and technologists. On the other hand, presently Wireless Sensor(More)
With the emergence of mobile computing and communication, low power device design and implementation have got a significant role to play in VLSI circuit design. Continuous device performance improvement has been made possible only through a combination of device scaling, new device structures and material property improvement to its fundamental limits.(More)
Particle Swarm Optimization (PSO) Algorithm is employed to determine the optimized system parameters of modulation doped Al<sub>x</sub>Ga<sub>1-x</sub>As/GaAs quantum well for better low-power and high frequency response. The mobility (ac and dc) of two-dimensional hot electrons in square quantum well of Al<sub>x</sub>Ga<sub>1-x</sub>As/GaAs is computed(More)
Small-signal ac transport of degenerate two-dimensional hot electrons in PbTe quantum wells is studied here incorporating deformation potential acoustic, polar optic and ionized background and remote impurity scatterings in the framework of heated drifted Fermi-Dirac distribution. The effects of double delta doping on millimeter and sub-millimeter wave(More)
—Millimeter and sub-millimeter wave response of two-dimensional hot electrons in double delta doped GaAs quantum well is studied here incorporating deformation potential acoustic, polar optic, ionized background and remote impurity scatterings in the framework of heated drifted Fermi-Dirac distribution function. The inclusion of delta doping is found to(More)
The workhorse of the present electronics industry, silicon MOSFET, is having a unique attribute; its logic characteristics improve as its dimensions are reduced. Without further reductions in operating voltage, future scaling may not be feasible. One possible solution is to introduce a new channel material in which charge carriers travel at a much higher(More)
