A stable feature extraction method in classification epileptic EEG signals

Abstract: Epilepsy is one of the most common neurological disorders. Electroencephalogram (EEG) signals are generally employed in diagnosing epilepsy. Therefore, extracting relevant features from EEG signals is one of the major tasks in an accurate diagnosis. In this study, the local ternary patterns, which is an image processing method, was improved in order to extract robust features from epileptic EEG signals. The EEG signals that were recorded by the Department of Etymology in the Bonn University were employed in the evaluation and validation of the proposed approach. Low and up features, which were extracted by the proposed one-dimensional ternary patterns, were classified by some machine learning methods such that support vector machine, functional trees, random forest (RF), Bayes networks (BayesNet), and artificial neural network, while the highest accuracies were obtained by RF. Achieved accuracies were found successful according to the current literature.

Environmental radioactivity assessment for Bayburt, Turkey

Abstract: This study assesses the results of environmental radioactivity measurements for Bayburt Province in the Eastern Black Sea area of Turkey. Using γ-ray spectrometry, activity concentrations of the natural radionuclides 226Ra, 232Th and 40K and a fission product 137Cs were investigated in soil samples. The activity concentrations of 226Ra, 232Th and 40K in various building materials such as sand, cement and marble and in drinking waters were determined. The activity concentrations vary from 16 to 54 Bq kg−1 for 226Ra, from 10 to 21 Bq kg−1 for 232Th and from 113 to 542 Bq kg−1 for 40K in building materials. The mean specific activity concentrations of 226Ra, 232Th and 40K in drinking waters were 93, 30 and 504 mBq l−1, respectively. The concentrations of gross α and β radioactivity in drinking water samples collected from four different sampling stations have been determined. The results show that the gross α and β activities are lower than the screening levels given by the World Health Organization (WHO), which are a maximum contaminant level of 0.5 Bq l−1 and 1.0 Bq l−1 gross α and β radioactivity, respectively, in drinking water. Indoor radon measurements were made in 44 dwellings in Bayburt by using Cr-39 detectors. Radon concentrations in dwellings in Bayburt varied from 17 to 125 Bq m−3 and the average value was 56 Bq m−3. The results obtained in this study indicate that the region has a background radiation level that is within the typical natural range and shows no significant departures from other parts of the country.
