In this paper the asymptotic expansion of first-order Melnikov function of a heteroclinic loop connecting a cusp and a nilpotent saddle both of order one for a planar near-Hamiltonian system are given. Next, we consider the bifurcation of limit cycles of a class of hyper-elliptic Liénard system with this kind of heteroclinic loop. It is shown that this system can undergo Poincarè bifurcation fr...

The serialization constraints imposed by true data dependences have always been regarded as an absolute dataflow limit on the parallel execution of serial programs. This paper describes value prediction, a new technique that allows data dependent instructions to issue and execute in parallel without violating program semantics. This technique exploits value locality, or the likelihood of the re...

Allocating resources to detect invasive pests, diseases, and pathogens on exposure pathways requires a trade-off between the need to detect as many contaminated items as possible and the need to acquire knowledge about contamination rates. We develop a model and an algorithm that provide guidance for the allocation of inspection resources across multiple dynamic pathways in cases where not ever...

Add an opening stage of signal acquisition to a canonical portfolio choice model and let investors have rational expectations about the ensuing Walrasian equilibrium. The expected marginal utility of a signal (its action value) falls in the number of signals and turns strictly negative at a finite number because signals diminish the asset’s excess return. There is a natural transparency limit a...

The correlations of lethal doses of various industrial chemicals for rats and mice with occupational exposure limit values were investigated. 50% lethal dose (LD50) values obtained by oral (p.o.) and intraperitoneal (i.p.) injection and 50% lethal concentration (LC50) values obtained by inhalation exposure were collected from Registry of Toxic Effects of Chemical Substances (RTECS). Threshold L...

In this paper the potential of kinetic energy absorption by means absorbing and storing mechanisms was discussed. The use absorbers is intended to reduce maximum working forces when stopping body.
