Analysis and reconstruction of ECG wave from sampled data is an important aspect in estimating the physiological condition of heart as well as in transmitting the ECG data to a remote location. In the present paper software based off line Fourier analysis technique has been reported to find the harmonic components of ECG wave of a normal subject. The(More)
We have investigated the electronic structure and the mechanism of the pressure induced phase transition of beryllium selenide (BeSe) by employing a first-principles pseudopotential method within the framework of density functional theory. Our study demonstrates that use of the hybrid PBE0 functional (PBE stands for Perdew, Burke and Ernzerhof) leads to(More)
