A note on stability shifting for the Muskat problem.

In this note, we show that there exist solutions of the Muskat problem that shift stability regimes: they start unstable, then become stable and finally return to the unstable regime. We also exhibit numerical evidence of solutions with medium-sized L(∞) norm of the derivative of the initial condition that develop a turning singularity.

Recursive Construction of Periodic Steady State for Neural Networks

We present a strategy in order to build neural networks with long steady-state periodic behavior. This strategy allows us to obtain 2” nonequivalent neural networks of size n, when the equivalence relation is the usual one in dynamical systems. As a particular case, we build a neural network with n neurons which realizes a cycle of period 2”.

Algorithms for Periodic Steady State Analysis on Electric Circuits

Designers of electric circuits are often interested in the behaviour of the designed circuits after turn-on effects have damped out. The traditional way to compute this long-term behaviour is by simulating the electric circuit over a large time interval. However, when the turn-on effects damp out slowly, the computational costs may become prohibitive. Many circuits have a periodic oscillating b...

Periodic Steady-State Analysis for Coupled Device and Circuit Simulation

A time-domain shooting method based coupled device and circuit simulator suitable for accurate simulation of RF circuits is presented. The simulator supports accurate numerical models for diodes, BJTs, and MOSFETs. These combined with the accelerated steady-state method allow accurate and efficient steady-state simulation of RF circuits.

Optimal Control for a Steady State Dead Oil Isotherm Problem

We study the optimal control of a steady-state dead oil isotherm problem. The problem is described by a system of nonlinear partial differential equations resulting from the traditional modelling of oil engineering within the framework of mechanics of a continuous medium. Existence and regularity results of the optimal control are proved, as well as necessary optimality conditions. Mathematics ...
