Probabilistic finite-difference time-domain simulations using stochastic electromagnetic macro-models
… systems, we propose the infusion of stochastic modeling with the electromagnetic macro-model in the finite-difference time-domain (FDTD) method. We provide a methodology for the efficient generation and utilization of the stochastic macro-model for the purpose of time-domain analysis in FDTD. …

Geosynchronous orbit determination using space surveillance network observations and improved radiative force modeling
Correct modeling of the space environment, including radiative forces, is an important aspect of space situational awareness for geostationary (GEO) spacecraft. Solar radiation pressure has traditionally been modeled using a rotationally-invariant sphere with uniform optical properties. This study …

Market Structure and Stabilization Policy
This thesis uses a macro model with a profit maximizing supply side to derive policy responses to stagflation. A dynamic profit maximizing theory of the firm's price and output adjustment process is first developed and then tested empirically. The role of market structure receives particular …

Radiation force modeling for ICESat precision orbit determination
… epoch-state batch filter, in which the dynamic models play a central role. Its implementation in the Multi-Satellite Orbit Determination Program (MSODP) originally included a box-and-wing model, representing the TOPEX/Poseidon satellite, to compute solar radiation forces. This “macro-model” has …

Statistical analyses of gravitational microlensing probability densities
Gravitational microlensing is a powerful modelling tool, that is essential in accurately understanding the lensing behavior of astronomically strong lensed objects. Using Joachim Wambsganss micro-magnification maps, we discuss the creation of a Monte-Carlo tool that can determine the likelihood for …

Homogenization of Partial Differential Equations with Random, Large Potential
… of PDE states that the solution of the initial model converges to the solution to a macro model, which is characterized by the PDE with homogenized coefficients. Particularly, we study PDEs with a large potential, a class of PDEs with a potential properly scaled such that the limiting equation …
