In this dissertation, we study two risk models. First, we consider the dual risk process which models the surplus of a company that incurs expenses at a constant rate and earns random positive gains at random times. When ...

The present article establishes connections between the structure of the deterministic Navier-Stokes equations and the structure of (similarity) equations that govern self-similar solutions as expected values of certain ...

Optimal well placement and optimal well control are two important areas of study in
oilfield development. Although the two problems differ in several respects, both are important
considerations in optimizing total oilf ...

PURPOSE: We analyze a recently proposed polyenergetic version of the simultaneous algebraic
reconstruction technique (SART). This algorithm, denoted pSART, replaces the monoenergetic
forward projection operation used b ...
A perfectly matched layer (PML) is widely used to model many different types of wave propagation in different media. It has been found that a PML is often very effective and also easy to set, but still many questions rem ...
