Demographic Stochasticity in Evolutionary Biology.
(2013)
Demographic stochasticity, the random fluctuations arising from the intrinsic discreteness of populations and the uncertainty of individual birth and death events, is an essential feature of population dynamics. Nevertheless ...
Nonholonomic Virtual Constraints and Gait Optimization for Robust Robot Walking Control.
(2016)
Bipedal locomotion is well suited for mobile robotics because it promises to allow robots to traverse difficult terrain and work effectively in man-made environments. Despite this inherent advantage, however, no existing ...
Discrete Ordinates Methods for Transport Problems with Curved Spatial Grids.
(2015)
The method of characteristics (MOC) has been favored for many recent whole core transport codes; some current research codes are: the nTRACER code from Seoul National University, the MPACT code from the University of ...
Efficient Output-Based Adaptation Mechanics for High-Order Computational Fluid Dynamics Methods
(2018)
As numerical simulations are applied to more complex and large-scale problems, solution verification becomes increasingly important in ensuring accuracy of the computed results. In addition, although improvements in ...
Reduced-Order Modeling of Turbulent Reacting Flows Using Inertial Manifold Theory
(2021)
Turbulent flows found in aerodynamics, propulsion, and other energy conversion sys- tems pose an inherent computational challenge for extensive predictive simulations. Over the last few decades, a statistical approach for ...
Multidisciplinary Study of Soft Shape Morphing Systems
(2021)
Nature abounds with examples of shape morphing systems where an entity either gradually grows into a complex 3-D shape pattern or rapidly morphs into a new configuration. Inspired by the shape shifting capabilities of ...
Symmetry and Reformulation: On Intellectual Progress in Science and Mathematics
(2022)
Science and mathematics continually change in their tools, methods, and concepts. Many of these changes are not just modifications but progress---steps to be admired. But what constitutes progress? This dissertation addresses ...
Autonomous Scene Understanding, Motion Planning, and Task Execution for Geometrically Adaptive Robotized Construction Work
(2019)
The construction industry suffers from such problems as high cost, poor quality, prolonged duration, and substandard safety. Robots have the potential to help alleviate such problems by becoming construction co-workers, ...
Efficient Algorithms for Light Transmission, Focusing and Scattering Matrix Retrieval in Highly Diffusive 3D Random Media
(2018)
Wavefront shaping provides an increasingly appealing avenue for imaging and other applications that require controlling electromagnetic waves passing through complex and disordered media. Indeed, these techniques allow ...
Spatial Nonlocality and Its Effects on the Scattering Characteristics of Wave-Bearing Media
(2022)
Reciprocity is the principle in the study of wave propagation that states that given a source and a receiver in a linear domain, switching their locations will not affect the received signal. Systems that break reciprocity ...
