In circuit simulation, it is of great importance to compute DC operating points of nonlinear circuits. However, the Newton-Raphson method employed in some SPICE-like simulators often fails to obtain a solution. To solve the non-convergence problem, homotopy methods receive abundant attention and have been studied from various standpoints. As to homotopy methods, the convergence property is fundamentally...
Recently, an efficient and globally convergent Newton fixed-point homotopy method (NFPH) for MOS transistor circuits has been proposed to find dc solutions of nonlinear circuits. However, the programming of sophisticated homotopy methods is often difficult for non-experts. In this paper, an effective netlist implementation method for the MOS NFPH method is proposed and it can implement the MOS NFPH...
The master production schedule (MPS) problem is a typical NP-hard problem. In this work, A MPS optimization model whose objectives are maximum utilization of equipment and minimum ratio between storage expenses and overdue fines is established with equipment capacity and product lead time as constraints. Then this model is implemented using a product encoding method and newly designed ant path searching...
Three-dimensional, unsteady Navier-Stokes equations have been solved to calculate the mixing between secondary injections at three different injection angles interact with the supersonic primary flow within the Hypersonic Low Temperature (HYLTE) nozzle. Results show that contact surface strentching and streamwise vortices especially counter vortex pairs (CVP) dominate and accelerate mixing. And the...
