Active research is being conducted in reducing power consumption of all the components of the Internet. To that end, we propose schemes for power reduction in network switches − Time Window Prediction, Power Save Mode and Lightweight Alternative. These schemes are adaptive to changing traffic patterns and automatically tune their parameters to guarantee a bounded and specified increase in laten...

Abstract: In this work, the most common problem of the modern power system named optimal power flow (OPF) is optimized using the novel meta-heuristic optimization algorithm ant lion optimizer (ALO). ALO is inspired by the hunting process of ant-lions in the natural environment. ALO has a fast convergence rate due to the use of roulette wheel selection method. For the solution of the optimal pow...

i ABSTRACT Nowadays transducers are ubiquitous as interfaces between the increasingly digital world and the real physical world. The same holds for the power amplifiers driving them. This thesis focuses on the design and optimization of high-voltage class-D amplifiers, which are used for driving capacitive piezoelectric actuator loads in active vibration/noise control applications. The main obj...

abstract: the combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. the response surface methodology (rsm) was used to determine the effect of nacl concentration (8%-20%), osmotic solution temperature (25-65°c), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 w) on water loss (wl), solids gain (sg),...

In modern digital circuits the total power attributed to wires is increasing. Reducing the power consumption in wires play a major role in low power design. Coupling transitions contribute to significant energy loss in deep sub-micron buses. Earlier schemes using the switching activity minimization based upon the substrate capacitances are not valid in these buses. Hence, a new low energy bus-e...
