Performance analysis of power and power variance for classification,detection and localization of epileptic multi-channel EEG

There are a large number of data sets of EEG signal for which, it is difficult to judge and monitor brain activity through observations. Epilepsy is a disorder in which a recurrent and sudden malfunction of the brain is characterized. It is proposed to classify, detect and localize Epileptic multi-channel EEG through various power and novel power variance features non-invasively. This work presents power spectral estimation (PSE) using time–frequency analysis of EEG signals in both parametric (FFT) and non-parametric methods (i.e. Welch, Burg, Covariance, MUSIC and Yule–Walker). To examine the robustness of power features for different methods, the analysis of p value is performed. The detection of epileptic seizure is classified using different kernels through SVM. It is observed from the PSE that the power features have higher values in epileptic subjects as compared to non-epileptic subjects. Amongst all the parametric and non-parametric methods, the MUSIC method gives the highest average power. Sensitivity, specificity, and classification accuracy are 100% for Welch, Burg, Covariance, and Yule–Walker methods while MUSIC and FFT methods deliver 98.73 and 99.52% respectively. The novelty is introduced through the quantification of power and power variance robust feature region/lobe-wise. This quantification is used for the localization of 25 epileptic subjects. Analysis of the parametric and non-parametric PSD methods for extraction of power and power variance features is not used by any study. These are effectively utilized for detection and localization of epilepsy non-invasively.

     

hner wire and cerclage wire) for the treatment of cubitus varus after supercondylar humeral osteotomy.Method

s: Thirty-three patients with cubitus varus were treated with two methods in the study.Among 15 patients in BTB group,12 patients were male and 3 patients were female,ranging in age from 13 to 24 years,with an average of 16 years,and the cubitus varus angel ranged from 17 degree to 34 degree(mean 26 degree).Among 18 patients in MTB group,15 patients were male and 3 patients were female,ranging in age from 12 to 22 years,with an average of 14 years,and the cubitus varus angle ranged from 17 degree to 40 degree(mean 29 degree).The results were evaluated
