We describe the application of the PVL algorithm to the small-signal analysis of circuits, including sensitivity computations. The PVL algorithm is based on the e cient computation of the Pad e approximation of the network transfer function via the Lanczos process. The numerical stability of the algorithm permits the accurate computation of the Pad e approximation over any given frequency range...

This investigation presents the effect of various parameters on foam stability and its rheological properties. The underlying idea of this experiment is generating of drilling foam with uniform bubbles. The main problem of foam using is controlling its stability during field application. The most important parameters which cause Instability in foam are gravity drainage, gas diffusion and bu...

The modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. In the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. The stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

Abstract Based on the aerodynamic layout of special projectiles, a targeted parameter solution algorithm is built by mechanical analysis model. The simulation software used to analyze ballistic stability. results show that with center gravity moving down helpful overcome rolling interference in uncontrolled flight.
