Robotic manipulation by pushing at a single point with constant velocity : modeling and techniques
In many mobile robotic manipulation tasks it is desirable to interact with the robot’s surroundings without grasping the object being manipulated. Non-prehensile manipulation allows a robot to interact in situations which would otherwise be impossible due to object size or mass. This thesis …

Modeling the Near-Surface Using High-Resolution Seismic Data
… reservoir imaging, an accurate near-surface velocity model is required. In this dissertation, I review the regional geology and geomorphology and the existing methods used for velocity modeling. A new method is developed, which depends on acquiring high-resolution shallow seismic data. The …

A Computational Study of the Hydrodynamics of Gas-Solid Fluidized Beds
Computational fluid dynamics (CFD) modeling was used to predict the gas-solid hydrodynamics of fluidized beds. An Eulerian-Eulerian multi-fluid model and granular kinetic theory were used to simulate fluidization and to capture the complex physics associated therewith. The commercial code ANSYS …

Velocity Studies in the Deepwater Gulf of Mexico: Keathley Canyon and Walker Ridge Areas
Two different, yet related, velocity studies were undertaken in and around the Keathley Canyon and Walker Ridge areas of the Gulf of Mexico. The first is a compilation of wellbore-salt-body interval velocities (Vint) from 55 wells exhibiting interval compressional-wave velocity variation from …

Structural settings inferred from gravity, magnetic and seismic data for Durban Basin, east coast offshore of South Africa
… using well tops of Jc-C1 well and sonic log; 3) Velocity modeling using seismic stacking velocities to convert time to depth surfaces and estimate sedimentary cover thickness. The Durban Basin extent in the study area was mapped and subdivided into shallow and deep basin, occupying the …

Dynamic Incompressible Navier-Stokes Model of Catalytic Converter in 1-D Including Fundamental Oxidation Reaction Rate Expressions
… it is evident from the history of catalyst modeling that precise reaction rate expressions are needed for accurate predictions. In order to determine the correct reaction rate expression, this work includes the history of the fundamental reactions of automotive catalysts including carbon …
