We present a Lagrangian particle/panel method for geophysical fluid flow described by the barotropic vorticity equations on a rotating sphere. The particles carry vorticity and the panels are used in discretizing the Biot-Savart integral for the velocity. Adaptive panel refinement and a new Lagrangian remeshing scheme are applied to reduce the computational cost and maintain accuracy as the flo...

Background. For X a smooth scheme over ~, K.t(X; 2g/{") is isomorphic to the usual rood(" topological K-theory of X as a complex manifold ([6]). In this case, Theorem 1 essentially answers a question of Fulton, [9], w 5. For many such X the mapp: Ko(X)~K~ot(X) cannot be a surjection, as non-trivial Hodge conditions on the Chern classes prevent some topological bundles from being stably algebrai...

Management of seizure activity in the neonatal foal presents a number of challenges. Control of neurological dysfunction and prevention of secondary physical injury is necessary in the first instance. Diagnosis of any underlying medical conditions must occur. Wide-ranging knowledge of the underlying cerebral pathology is essential when formulating a treatment plan. The relatively limited knowle...

A brief computational description of the Lin-Rood shallow water finite volume (SWfv) model is provided. Along side, salient features of the model are described. 4D-VAR data assimilation experiments using this model provided us avenues to study model error introduced by different high order advection schemes (such as van Leer and PPM) in the framework of 4D-variational data assimilation. This mo...

We provide a strategic implementation of the sequential equal surplus division rule (Béal et al., 2014). Precisely, we design a non-cooperative mechanism of which the unique subgame perfect equilibrium payoffs correspond to the sequential equal surplus division outcome of a superadditive rooted tree TU-game. This mechanism borrowed from the bidding mechanism designed by Pérez-Castrillo and Wett...

This paper proposes a structure for utility functions that are useful when modeling and solving important classes of practical planning applications--problems that are not adequately characterized by an additive utility function, but still have some additive structure. The structure is Xu(t)*mod(t,...) where is a function of how and when a single task is completed and rood(t,...) captures the e...

introduction: in recent years, due to the reduction in surface water, utilization of groundwater has been increased to meet the growing demand of irrigation water. the quality of these water resources is continually changing, due to the geological formations, the amount of utilization, and climatic parameters. in many developing countries, the irrigation water is obtained from poor quality grou...
