Efficiency of harvesting energy from colored noise by linear oscillators.
We investigate the performance of a linear electromechanical oscillator as an energy harvester of finite-bandwidth random vibrations. We derive exact analytical expressions for the net electrical power and the efficiency of the conversion of the power supplied by the noise into electrical power for arbitrary colored noise. We apply our results to the important case of exponentially correlated n...
متن کاملEffect of colored noise on networks of nonlinear oscillators.
We discuss noise-induced pattern formation in different two-dimensional networks of nonlinear oscillators, namely a sequence of biochemical reactions and the Lorenz system. The main focus of the work is on the dependence of these patterns on the correlation time (i.e., the color) of exponentially correlated Gaussian noise. It is seen that in the nonchaotic case, the homogeneity (or average clus...
متن کاملControlling Neuronal Noise Using Chaos Control
1 Chaos control techniques have been applied to a wide variety of experimental systems, including magneto-elastic ribbons 1], lasers 2], chemical reactions 3], arrhythmic cardiac tissue 4], and spontaneously bursting neuronal networks 5]. An underlying assumption in all of these studies is that the system being controlled is chaotic. However, the identiication of chaos in experimental systems, ...
متن کاملModeling and Estimation of Phase Noise in Oscillators with Colored Noise Sources
The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. However, the real systems perform below capacity limits, mainly due to channel estimation error and hardwar...
متن کاملAnalytical calculation of the frequency shift in phase oscillators driven by colored noise: implications for electrical engineering and neuroscience.
We provide an analytical expression for the mean frequency shift in phase oscillators as a function of the standard deviation, sigma and the autocorrelation time, tau of small random perturbations. We show that the frequency shift is negative and proportional to sigma;{2} . Its absolute value increases monotonically with tau , approaching an asymptote determined by the L2 -norm of the phase-res...
