Most of the traditional RF circuits are static or minimally tunable using some digital controllability. For example, high power, low power and shut down modes available in commercially transceivers. If available, tuning knobs affect different specifications an interdependent manner, resulting changing several when only one needs to be tuned. This is not enough for optimal operation complete self-aware self-adaptive systems. Independent orthogonal tunability important conflicting built-in...
Prior research has established that dynamically trading-off the performance of radio-frequency (RF) front-end for reduced power consumption across changing channel conditions, using a feedback control system modulates circuit and algorithmic level "tuning knobs" in real-time based on received signal quality, leads to significant savings. It is also known optimal strategy depends process conditions corresponding RF devices concerned. This an explosion search space needed find best strategy,...
A model of preferential solvation is presented in terms solute–solvent and solvent–solvent interactions relative size the solvent molecules compared with other models. The interrelation between various parameters discussed. When component are same size, stepwise exchange quasi-lattice quasi-chemical give identical results. models have been applied to extract characterising Dimroth–Reichardt betaine dye binary mixed solvents from UV–VIS spectroscopic data. possibility incorporating effect...
Modern MIMO RF transceiver systems are designed to operate reliably under diverse channel conditions leading incorporation of significant performance margins in systems. In general, across dynamically varying conditions, the fidelity front end devices can be traded-off against power consumption without compromising system-level BER limits. this work such a real-time vs. modulation front-end is demonstrated. Through multi-dimensional optimization technique, power-optimal configuration for...
Modern radio front ends are required to operate over diverse channel conditions requiring the incorporation of significant performance overheads into their design. This results in significantly higher power consumption most operational period since worst case channels not statistically prevalent. Adaptive systems solve this problem by adapting and depending on conditions. In paper, it is demonstrated that upon throughput requirements system multiple low-power adaptation modes can be...
The present work reports the microscopic details of anatase (A) to rutile (R) phase transformation in a Mn-doped TiO<sub>2</sub> system.
Earlier research has demonstrated that the power in a RF front-end can be traded off for performance real-time to operate at threshold of acceptable operation using lookup table driven controller. Such controller needs careful calibration and suffers from modeling inaccuracies which must guardbanded during resulting "less than optimal" consumption. In this work we propose real time fuzzy noise-distortion control algorithm low-power adaptation continuously changing channel conditions. As...

Preferential solvation of N-ethyl-4-cyanopyridinium iodide and pyridinium betaine has been studied at various temperatures by monitoring the thermosolvatochromic band solute in mixed binary solvents. Parameters characterising preferential have calculated results interpreted terms existing models. A study thermochromism solutes solvents may provide information about solvent non-ideality.
