The eeects of nite-rate wall catalyticity are evaluated by numerical simulations of hypersonic non-equilibrium ows. Several models derived from speciic gas surface chemical schemes taking into account elementary steps, such as adsorption, surface recombination and desorption, are considered. The models have been incorporated in a mixed nite-element//nite-volume code for reactive viscous ow as s...

Electrophoretic studies were made on vaccine virus, collodion particles, and glass particles suspended in 0.01 molar buffer solutions at pH 7.9, in which the moving boundary method was used. In some experiments, uncoated particles were used; in others, particles were coated with proteins and then resuspended in the buffer solution after a washing; in still others, an excess of protein which had...

For axiom A diffeomorphisms and equilibrium state, we prove a Large deviation result for the sequence of successive return times into a fixed open set, under some assumption on the boundary. Our result relies on and extends the work by Chazottes and Leplaideur who where considering cylinder sets of a Markov partition.

The paper describes variations of the classical k-means clustering algorithm that can be used effectively to address the so called Web-site Boundary Detection (WBD) problem. The suggested advantages offered by these techniques are that they can quickly identify most of the pages belonging to a web-site; and, in the long run, return a solution of comparable (if not better) accuracy than other cl...

This paper proves that the optimal exercise time for the holder of an American option depends upon the physical drift of the underlying asset and the utility of the option holder. We illustrate our results by applying them to several families of utility functions, namely the CARA, the HARA, and the expected return. While the option holder maximises his utility, the issuer gains from the di eren...

acceleration, a is the coefficient of friction, and u is the blood velocity. The boundary condition for u is that it must return to and remain at zero at the end of diastole. The value of a which will satisfy this condition is the proper value. It can be demonstrated that a must lie somewhere between 0 and 2A.-C. The proper value may be obtained by a tedious graphic method. However, analog comp...

We consider U(1) gauge fields in a slice of AdS5 with bulk and boundary mass parameters. The zero mode of a bulk U(1) gauge field can be localized either on the UV or IR brane. This leads to a simple model of millicharged particles in which fermions can have arbitrarily small electric charge. In the electroweak sector we also discuss phenomenological implications of a localized U(1)Y gauge boso...

It has been shown experimentally that mixtures of two types of particles, namely, elementary bodies of vaccinia and collodion particles coated with protein, sediment with a single boundary in the analytical centrifuge. Such mixtures have been shown to develop one or two boundaries on electrophoresis in the Tiselius apparatus, depending on the type of coating on the surface of the collodion part...
