Asynchronous circuit elements are quiescent whenever they are not actually performing a computation, and thus they potentially waste less power than synchronous circuits. However, previous research on asymptotically non-dissipative computation has concentrated exclusively on synchronous computing models, while researchers on asynchronous circuits have ignored the issues of conservative, reversi...

The paper is concerned with asymptotic stability properties of linear switched systems. Under the hypothesis that all the subsystems share a non strict quadratic Lyapunov function, we provide a large class of switching signals for which a large class of switched systems are asymptotically stable. For this purpose we define what we call non chaotic inputs, which generalize the different notions ...

Nine new 2-D OOCs are presented here, all sharing the common feature of a code size that is much larger in relation to the number of time slots than those of constructions appearing previously in the literature. Each of these constructions is either optimal or asymptotically optimal with respect to either the original Johnson bound or else a non-binary version of the Johnson bound introduced in...

We present exact spherically symmetric dyonic black hole solutions in fourdimensional and higher dimensional Einstein-Maxwell-dilaton gravity with Liouvilletype potentials for the dilaton field. These solutions have unusual asymptotics–they are neither asymptotically flat nor asymptotically (anti-) de Sitter. The solutions have one or two horizons hiding a curvature singularity at the origin. A...

The local stability of a quasi-linear age-size structured population model studied in Tchuenche (2007) is analysed. If a certain threshold parameter known as the basic reproductive rate is less than unity, then the trivial steady state is locally asymptotically stable. Also, it is shown that if the only real root of the equation R(m′) = 1 is negative, then, the non trivial steady state is local...

Numerical solutions of the Einstein-Yang-Mills equations with a negative cosmological constant are constructed. These axially symmetric solutions approach asymptotically the anti-de Sitter spacetime and are regular everywhere. They are characterized by the winding number n > 1, the mass and the non-Abelian magnetic charge. The main properties of the solutions and the differences with respect to...
