Qualitative and Quantitative Evaluation of EEG Signals in Epileptic Seizure Recognition
A chaos-ANFIS approach is presented for analysis of EEG signals for epileptic seizure recognition. The non-linear dynamics of the original EEGs are quantified in the form of the hurst exponent (H) and largest lyapunov exponent (λ). The process...

Estimation of central shapes of error distributions in linear regression problems
Investigation of stress exponent in the room-temperature creep of Sn-40Pb-2.5Sb solder alloy
the correspondence of the creep results. Stress
exponent values have been determined through these methods and in all cases the calculated exponents are in good agreement. The stress exponent
values in the range 2.55–3.20, depending on the testing...
Stochastic nature of series of waiting times
that the “waiting times” series for a given increment level have long range correlations with Hurst exponents belonging to the interval 1/2<H<1. We also study positive-negative level asymmetry of the waiting time distribution. We find that the logarithmic...
On the exponent of the Schur multiplier of a pair of groups
We present some bounds for the exponent of the Schur multiplier of
a pair of groups $(G,N)$ in terms of the exponent of $G$, when
$G$ is the semidirect product of $N$ by $Q$, and also in terms of
the exponent of $N$ when...

Computation of entropy increase for Lorentz gas and hard disks
. The computations
show exponentially monotonic increase during initial time of rapid approach to equilibrium. The rate of entropy
increase is bounded by sums of positive Lyapounov exponents...
A Bound for the Exponent of the Schur Multiplier of some Finite p-Groups
Let $G$ be a finite $p$-group of exponent $p^e$. The paper is
devoted to present a new bound for the exponent of the Schur multiplier of $G$,
when $G$ is of class 3, 4 or 5 and $e$ satisfies in some conditions....
