New positioning system for the CSL Robotics Laboratory Testbed
… Two modes of operation are implemented, Barycentric and Change of Axes. The new system is able to calculate position using the two methods, and 90% or more of the data points collected in each set lie within 0.05 units from true position. Heading is also calculated, but further testing is …

Optimal transportation and barycenter problems via convex functions
… and introduce new cases. Chapter six develops barycentric applications. The rst section develops 2-Wasserstein barycenter results. Using a xed-point framework introduced in chapter four, immediate convergence and explicit representation of the barycenter is demonstrated for some classes of …

The ramifications of diffusive volume transport in classical fluid mechanics
… velocity v[sub]v. The latter differs from the barycentric velocity V[sub]m by the vector field j[sub]v, where j[sub]v = v[sub]v - v[sub]m represents the heretofore largely ignored diffusive transport of volume. We will begin by giving a motivating discussion containing example problems which …

Quantification of Reynolds-averaged-Navier-Stokes Model Structural Hypothesis Uncertainty in Transitional Boundary Layer and Airfoil Flows
… perturbation was carried out through the barycentric map. For the T3A flow, most of the model structural hypothesis uncertainty was concentrated in the laminar-turbulent transition region. For the SD7003 flow, the reattachment point was well encompassed within the uncertainty bound. The …

Approximation of Parametric Dynamical Systems
Dynamical systems are widely used to model physical phenomena and, in many cases, these physical phenomena are parameter dependent. In this thesis we investigate three prominent problems related to the simulation of parametric dynamical systems and develop the analysis and computational framework …

Image Based View Synthesis
… employing a trinocular-stereo algorithm and barycentric blending technique, we generate an arbitrary novel view to navigate the scene in a 2D space. Furthermore, after self-calibration of the cameras, a 3D model can also be correctly augmented into this virtual environment synthesized by the …

Multi-Platform Molecular Data Integration and Disease Outcome Analysis
… effect on each pixel and the use of a barycentric coordinate system to identify more pure-volume pixels and to test those identified by CAM-CM. Tested on simulated DCE-MRI data, the enhanced CAM-CM achieved better performance in terms of accuracy and reproducibility.

Optimal transport: theory, algorithms and applications
… OT problem, as well as a relaxed version of the barycentric weak OT problem. Chapter 4 is about OT in applications. We summarize the contributions from [96] in Appendix A.2 and [153] in Appendix A.6. These contributions do not lie within OT itself, but in an approach using it as a tool. First, in …
