Proportional navigation target tracking
… model, which is not found in previous target models, is the end goal or destination constraint inherent in the proportional navigation guidance law: the anti-ship missile's goal is to strike ownership; the proportional navigation trajectory always passes through the origin. Because of model …

Modeling drivers' acceleration and lane changing behavior
… development cf microscopic traffic performance models which includes the acceleration and lane changing models. It enhances the existing models and develops new ones. Another major contribution of this thesis is the empirical work, i.e., estimating the models using statistically rigorous methods …

Quasar Outflows: Their Scale, Behavior and Influence in the Host Galaxy
… is much larger than predicted from radiative acceleration models (~0.01-0.1 pc), suggesting that outflows appear much farther from the central source than is generally assumed. The outflow in SDSS J0831+0354 was found to carry a kinetic luminosity of 10<sup>45.7</sup> erg/s, which corresponds …

Path Selection to Minimize Energy Consumption of an Electric Vehicle using Synthetic Speed Profiles and Predictive Terminal Energy
… the creation of a velocity profile which models how the route will be driven and a powertrain model which relates energy consumption to the constructed velocity profile. Existing research efforts related to both of these aspects typically require complex analysis and proprietary vehicle …

Evolution of 3-d magnetic topology in flare-productive active regions
… with numerical MHD simulations and theoretical models. The main findings in this dissertation are briefly summarized as follows: (1) the white-light observation of S sunspots reveal the rapid penumbral decay and central umbral/penumbral darkening associated with flares; (2) the magnetic …

An Analysis of EcoRouting Using a Variable Acceleration Rate Synthesis Model
… distance between the origin and destination, the acceleration rate of the vehicle, cruise speed and jerk rate as inputs to simulate driver behavior on a given route. A new approach is presented in this thesis that weighs the energy consumption for different routes and chooses the route with the …

Eco-Driving in the Vicinity of Roadway Intersections - Algorithmic Development, Modeling and Testing
… time spent accelerating and decelerating, and/or acceleration or deceleration levels) in the objective function and fail to explicitly optimize vehicle fuel consumption levels. Furthermore, the majority of these models do not capture vehicle acceleration and deceleration limitations in addition to …

Semi-implicit schemes for compressible fluids in elastic pipes and a-posteriori sub-cell finite volume limiting techniques for semi-implicit Discontinuous Galerkin schemes for hyperbolic conservation laws on staggered meshes
… pipes. We consider two families of differential models that can be used to predict the pressure and velocity distribution along the tube. One is the so called 2Dxr PDE model which is derived from the full compressible Navier-Stokes equations under the assumptions of a hydrostatic pressure and an …
