Brain Computer Interface (BCI), controlling of computer using brain, is a new dimension in the field of human computer interface (HCI). Stimulation, signal analysis and pattern recognition are three most important units in BCI system. But it is very confusing to select a stimulation technique, to select a domain to analysis EEG signal and to choose a(More)
Inherent features of Electroencephalogram (EEG) signal acts a vital role to determine the human brain condition. The motivation of this paper is to extract the inherent features of EEG signal by visual stimulation of different colors such as green, red, blue, yellow. For stimulation Microsoft PowerPoint slide of different colors are shown to the subjects.(More)
Development of visual recognition system using electroencephalogram (EEG) signal is the most challenging task in the present computational neuroscience. The goal of this work is to recognize different numbers using salient features of EEG signal. Using data acquisition system, EEG signal is recorded applying visual stimulation. Visual stimulation of(More)
This work reports on development of an optimized analytical model to investigate the current-voltage (J-V) characteristics of a lightly doped CdTe-based thin film solar cell considering voltage-space dependency of electric field in the absorber region. Following the theory of perturbation, the intractable mathematical equations have been solved(More)
Support Vector Machine (SVM) is one of the most popular machine learning algorithms for pattern recognition of a specific dataset. The percentage of accuracy from a defined SVM model greatly depends on the selection of appropriate attributes for SVM model. But the most effective attributes selection for SVM algorithm is one of the most difficult tasks for(More)
This work develops an analytical model including the effect of series resistance as well as the surface recombination occurred at the edges. Mathematical intractability caused for the inclusion of series resistance has been resolved using the concept of the perturbation theory. Introducing a new boundary condition at the emitter edge of the fully depleted(More)
This paper attempts an analytical approach to accurately determine common-mode rejection ratio (CMRR) considering the effects of various non-idealities such as the presence of channel length modulation, body effect, finite resistance of the current source, mismatches in transconductances and drain resistances between the two driver MOSFETS of a common(More)
