We present experimental results on statistics of polymer orientation angles relative to the shear plane and tumbling times in shear flow with thermal noise. The strong deviation of the probability distribution functions (PDFs) of the orientation angles from Gaussian PDFs was observed in good accord with theory. A universal exponential PDF tail for the tumbling times and its predicted scaling wi...

Recurrent spiking neural networks can provide biologically inspired model of robot controller. We study here the dynamics of large size randomly connected networks thanks to ”mean field theory”. Mean field theory allows to compute their dynamics under the assumption that the dynamics of individual neuronsare stochastically independent. We restrict ourselves to the simple case of homogeneous cen...

nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. to design and implement suchcontrol systems, having information about traffic light colors is essential. there are the wide variety oftraffic lights in terms of light intensity and color. therefore it seems that design and ...

The scalp potentials originate in neuronal activity in the brain cortex, and neuronal abnormality causes scalp potential abnormality. As a measure of scalp potential abnormality, the normalized power variance, NPV, of EEG signals is introduced, where its mean m and standard deviation are defined for each of 21 EEG channel over a group of normal controls. When an NPV value of a subject to be tes...

This paper proposes that speech analysis be used to quantify prosodic variables in presentation speech, and reports the results of a perception test of speaker liveliness. The test material was taken from a corpus of oral presentations made by 18 Swedish native students of Technical English. Liveliness ratings from a panel of eight judges correlated strongly with normalized standard deviation o...

A chart was developed which gives the volume-normalized extinction coefficient for log-normally modelled, multimodal particle volume distributions. The real part of the particle refractive index ranges from 1.30 to 1.70. Two adjustment charts modify the main chart for an imaginary part of the refractive index different from 0.02, and for a geometric standard deviation of the modal volume distri...

Let X1, X2, . . . be independent random variables with zero means and finite variances, and let Sn = ∑n i=1Xi and V 2 n = ∑n i=1X 2 i . A Cramér type moderate deviation for the maximum of the self-normalized sums max1≤k≤n Sk/Vn is obtained. In particular, for identically distributed X1, X2, · · · , it is proved that P(max1≤k≤n Sk ≥ xVn)/(1 − Φ(x)) → 2 uniformly for 0 < x ≤ o(n1/6) under the opt...

 Abstract: Recently, the normalized subband adaptive filter (NSAF) algorithm has attracted much attention for handling the colored input signals. Based on the first-order Markov model of the optimal tap-weight vector, this paper provides a convergence analysis of the standard NSAF. Following the analysis, both the step size and the regularization parameter in the NSAF are jointly optimized in ...

In this paper, an adaptive transmission scheme using QAM and LDPC code is proposed for an OFDM cellular system employing FDD. By approximating the LLR distribution to a Gaussian distribution, only two parameters, the mean and the normalized standard deviation, are required to be fed back to the transmitter. Thus, only a few more bits are needed compared to the feedback information in currently ...

A wide range of glassy and disordered materials exhibit complex, nonexponential, structural relaxation (aging). We propose a simple nonlinear rate equation δ = a[1-exp(b δ)], where δ is the normalized deviation of a macroscopic variable from its equilibrium value, to describe glassy relaxation. Analysis of extensive experimental data shows that this equation quantitatively captures structural r...
