When a Hamiltonian system has a \Kinetic + Potential" structure, the resulting ow is locally a geodesic ow. But there may be singularities of the geodesic structure, so the local structure does not always imply that the ow is globally a geodesic ow. In order for a ow to be a geodesic ow, the underlying manifold must have the structure of a unit tangent bundle. We develop homological conditions ...

Abstract. In this paper, a Cascaded Lattice Boltzmann Method with second order slip boundary conditions is developed to study gas flows in a microchannel in the slip and transition flow regimes with a wide range of Knudsen numbers. For the first time the effect of wall confinement is considered on the effective mean free path of the gas molecules using a function with nonconstant Bosanquet para...

This study investigates the effects of reductions in nitrogen oxide (NOx) emissions from major point sources on daily maximum 8-h ozone concentrations in the eastern United States. The Community Multiscale Air Quality (CMAQ) model was utilized in photochemical simulations on a matrix of modeling scenarios permitting an examination of the separate effects of emission changes and meteorological i...

A bandwidth control mechanism is proposed for ATM networks that can control the usage of bandwidth in the presence of both connection oriented and connection less tra c as well as multiple classes of connectionless tra c The bandwidth control mechanism operates at three levels At the topmost level bandwidth is dy namically regulated between connection oriented and connectionless tra c based on ...
