Abstract:
One of the most important problems in modern finance is to understand how best to model the occurrence of jumps in asset pricing models. With this issue in mind, the main topic of this thesis is the development of a set of asset pricing models, driven by Levy uncertainty, applicable across a wide range of asset classes. In particular, we model the term structure of interest rates in a Levy setting, by use of the so-called positive interest models of Flesaker and Hughston. We begin with a brief review of the term-structure literature. We then introduce elements of the theory of Levy processes a

Abstract:
In many different engineering branches, computer-based simulations for analyzing systems’ behavior hold a growing importance for the development of new products and new technical solutions. Pursuing this aim requires two stages: building a mathematical model of the system and solving it employing a computer. Algorithms for calculating the numerical solution of differential equations, called numerical integrators, become thus extremely decisive as they influence the reliability of the simulation results. Many dynamical systems exhibit properties that are preserved by the flow, e.g., energ

Abstract:
Multi-vehicle systems offer many advantages in engineering applications such as increased efficiency and robustness. However, the disadvantage of multi-vehicle systems is that they require a high level of organization and coordination in order to successfully complete a task. Formation control is a field of engineering that addresses this issue, and provides coordination schemes to successfully implement multi-vehicle systems. Two approaches to group coordination were proposed in this work: geometric and self-organizing formations. A geometric reconfiguring formation was developed using the le
