Abstract : Spectral and Spatial Feature Extraction of Electroencephalographic (EEG) Data Using Independent Component Analysis (ICA)
|
|
|
Abstract: Purpose of this research is to extract features associated with human brain signal related to electroencephalographic measurements and classification of extracted EEG signals to the relevant the brain region. EEG brain signals from 14 electrodes placed on the human scalp is recorded non-invasively using Emotiv EPOC / EPOC+:Scientific contextual EEG system with a sampling rate of 128 Hz. EEG data of human brain functions related to evoked motor imagery tasks consisting of two different classes of activities, namely imagination of right arm-movement i.e. arm down (termed here as PUSH) and arm up (termed here as PULL) for three healthy subjects is recorded. After pre-processing for noise and artifacts removal, the EEG signals associated with investigated evoked activities are extracted using Independent Component Analysis (ICA). The results obtained show good contrast plots for the extracted brain signals recorded on F7, FC5 and FC6 electrodes, decomposed on independent components, namely IC1, IC4, IC5, IC6. Classification of extracted features is mapped on to the motor imagery parts of human brain. The algorithm based on independent component analysis gives good results for feature extraction corresponding to evoked signals. Power spectra are also determined for the extracted independent components. Keywords: Electroencephalogram, electrocorticogram, independent component analysis, brain computer interface, event related potential. |
Abstract : Heritability Estimates for some Performances Traits of Baluchi Sheep
|
|
|
Abstract: Present study was carried out to estimates the genetic parameters of Baluchi sheep during the year 2015 at Bhagnari cattle Cum Baluchi Sheep Farm Usta Muhammad, Baluchistan. The recorded data including (lactation yield and lactation length) was collected for the period 2005 to 2014.The results of current study revealed that average milk yield and lactation length was found 95.1±11.122kg and 123.60±8.44days of Baluchi sheep. The results for heritability and correlation estimates for lactation yield and lactation length was observed 0.113, 0.126 and 0.26, respectively. There was positive and low heritability and correlation was worked out for lactation yield and lactation length. Due to low results heritability and correlation estimates of some performance traits of Baluchi sheep, it was concluded that improvement can be achieved by process of mass selection. Keywords: Baluchi sheep, heritability, correlation, milk yield, lactation length. |
Abstract : Spatial Distribution of Noise Released from Iron and Steel Industry and their Effects on Human Health in the Lahore City, Pakistan
|
|
|
Abstract: This research investigates the phenomenon of perception of people about industrial noise pollution and its effects on human health. Thirty-six (36) industries were selected for estimation of noise levels and its effects on human health. Concurrently, samples of one hundred and fifty (150) respondents were also taken from nearby residential area, using random sampling method. The key tool of data collection was well-structured questionnaires consisting of twenty-one questions. Chi-Square test was used for examination of data, which illustrated effects of industrial noise on people living in industrial zone. The noise level results indicated that the mean values were exceeding permissible environmental standard used in Pakistan. Majority of respondents (50.6 %) were conscious about the basic reason of noise pollution in study area. Eighty-two percent (82%) people have opinion that old technology was the basic cause for noise pollution. It was shocking to see the results which indicate that 99.8% people are suffering from noise related diseases. This include 81.3% with increase anger, 81.5% with ear ache, 16% with ear discharge, 79.3% with high blood pressure, 78% with depression, 77.3% temporary hearing loss, 9.3% permanent hearing loss. Only 23.3% of people conduct regular hearing test. Keywords: Noise, pollution, spatial distribution, GIS, SPSS, Buffers. |
