In this paper we use viscosity solution methods to show that almost integrable Hamiltonian systems are not smoothly integrable at rotation numbers which are exponentially close to resonances.

In this paper we show how to use a Tug-of-War game to obtain existence of a viscosity solution to the infinity laplacian with nonhomogeneous mixed boundary conditions. For a Lipschitz and positive function g there exists a viscosity solution of the mixed boundary value problem,

This poster will describe the security problems of the emerging vehicular networks. It will also outline the solution architecture and several of its components.

We present a generalization of Zubov’s method to perturbed differential equations. The goal is to characterize the domain of attraction of a set which is uniformly locally asymptotically stable under all admissible time varying perturbations. We show that in this general setting the straightforward generalization of the classical Zubov’s equations has a unique viscosity solution which character...

A surgical head rest is described that gives good wrist support, provides space to place instruments, and allows drainage of irrigation fluid.

conclusions according to the results, it can be concluded that the titanium catalyst doped with iron (fe+3-tio2) processes is an appropriate method for reducing atrazine in polluted water resources. results the results demonstrated that the atrazine removal rate increased by decreasing the initial atrazine concentration and the maximum rate of atrazine removal (41.72%) was at ph = 11, atrazine ...

introduction: arsenic is known as a carcinogenic compound in drinking water . it can cause acute and chronic effects on human health. in this study, the effect of polyamidoamine dendrimer generation 3(pamam g3) as adsorbents for removal of arsenic (v) from aqueous solutions was evaluated.     methods: adsorption experiment was studied in batch system and the effect of different variables like p...

_____________ _ A new membrane oxygenator has been introduced by Travenol Laboratories with continued development carried out by Sarns Inc. The polypropylene hollow fibers are wound in a pattern perpendicular to the blood flow path and serve as the conduit for the ventilating gas. The membrane surface area is 1.8 M2. The device contains an integral stainless steel bellows heat exchanger and a t...
