MODEL-BASED 3-D VISION
This thesis is divided into two pans. The first part discusses in length the state-of-an techniques in 3-D vision, specifically 3-D data acquisition, representation, and recognition. The second part, which forms the basis for this thesis, deals with a specific method of identifying 3-D objects …

3-D Numerical Modeling of Turbidity Currents
<p>The hydrodynamics of density currents are difficult to study in the natural envi- ronment, whereas laboratory experiments are limited to small-scale flows, are time- consuming and are not necessarily easier when it comes to measuring flow properties or establishing relationships between the …

Motion -Compensated 3-D Generalized Series Imaging
Three-dimensional magnetic resonance (MR) imaging is highly desirable from the standpoints of minimum voxel size, volumetric coverage and signal-to-noise efficiency. Unfortunately, long scan times have traditionally precluded the use of 3-D imaging in applications where simultaneous resolution of …

3-D body mapping with computer vision
The potential and accuracy aspects of a completely automated stereo photogrammetric vision system for performing precise 3-D body mapping of whole human bodies have been investigated. A prototype vision system by integrating structured lighting, computer vision, and stereophotogrammetric techniques …

Development of a 3-D pen input device
The principal objective of this research is to demonstrate the capability of obtaining the acceleration in the navigation frame of a unistroke which can be written on any surface or in the air while correcting integration errors from the measurements of the IMU (Inertial Measurement Unit) of the …

A 3-D Model of the Auroral Ionosphere
<p>A new 3-D model of the high latitude ionosphere is developed to study the coupling of the ionosphere with the magnetosphere and neutral atmosphere. The model consists of equations describing conservations of mass, momentum and energy for the six ionospheric constituents (O+, NO+, N+2 , O+2 , N+ …

Biomimetic and vascularized 3-d liver cancer model
Anti-angiogenic drugs have failed to show significant extended mortality, except when co-administered with chemotherapy drugs in clinical trials. This should be predicted by in vitro models, and yet 2D in vitro models of liver cancer co-administered with these two types of drugs show increased cell …

Surface wave propagation in 3-D anelastic media
Lateral perturbations in anelasticity (Q) and wave speed together provide important constraints on thermal and chemical structures in the mantle. In present-day tomography studies of global wave speed and anelasticity, the significance of 3-D wave speed and 3-D Q structures on surface wave travel …

MOLTEN-BASED 3-D DIRECTWRITE FABRICATION OF MICRO STRUCTURES
The micro fabrication is the backbone of information age. From phones people use daily to the satellite in the orbit, they all rely on the control unit, sensors that made by microfabrication techniques. With decades of rapid development, the micro fabrication technology has reached a dimension that …

3-D Computational Investigation of Viscoelastic Biofilms using GPUs
<p>A biofilm is a slimy colony of bacteria and the materials they secrete, collectively called “extracellular polymeric substances (EPS)”. The EPS consists mostly of bio-polymers, which cross link into a network that behave viscoelastically under deformation. We propose a single-fluid …
