A class of exact nonstatic solutions is obtained for Einstein field equations in a closed elliptic Robertson-Walker spacetime filled with viscous perfect fluid in the presence of attractive scalar fields. The solutions characterize strong interaction

Robertson—Walker cosmological models with bulkviscosity are investigated explicitly with equation of statep=(γ-1)e. In particular, the physical nature of the extreme cases, i.e., degenerate vacuum bulkviscous fluid model and bulkviscous stiff flui

A multiple current source inverter system with 8.75 per cent total harmonic distortion is proposed. It has negligible lower order harmonics and the predominant harmonics are 23rd and 25th. This has been achieved by cascading a small kVA PWM inverter

A McMurray commutation circuit with a (di/dt) inductor in series with the main thyristors is analysed. Analysis shows that advanced firing on the commutation current ring is necessary in order to avoid the commutation failure in case of sudden loadin
