LINKING ALLOMETRIC SCALING THEORY WITH LIDAR REMOTE SENSING FOR IMPROVED BIOMASS ESTIMATION AND ECOSYSTEM CHARACTERIZATION
… toward theoretical predictions, suggesting that theory may be a useful constraint on allometry in certain forests. Second, we shift to an analysis of empirical allometries by developing an algorithm to extract individual crown information from forest systems and using it for biomass mapping and …

Formation of nanoemulsions and entrapped microdroplets
… energy methods. Specifically, we develop a new scaling theory for high energy methods to control the droplet size of nanoemulsions by taking into account the effect of Ohnesorge number, a parameter that quantifies the internal viscous effects of the droplet. We validate the scaling theory with a …

Interactions Between Polyethylene Glycol Chains and Proteins and Chemically Selective Surfaces
… 'simple' polymers such as the excluded volume or scaling theory. Rather, these studies show that its biological response is coupled to the specific physico-chemical attributes of its segments and hence, to the competitive interactions between the solvent and other entities such as non-polar groups …

Thermal pollution modeling of the New River
… A description of modeling methods, Froude scaling theory, present methods of measuring waste heat at power plants, and an evaluation of modeling as an effective method of predicting the thermal plume from a power plant is included.

MOMENTUM SIGNATURES OF THE ANDERSON TRANSITION
… peaks, CBS and CFS. We develop finite-time scaling theory for the angular width of the CBS peak and in the height of the CFS peak. We demonstrate how to extract properties like critical exponent, the mobility edge and signatures of multifractality from this finite-time analysis. These …

Monte Carlo computer simulation of sub-critical Lennard-Jones particles
… above and below the percolation threshold. Using scaling theory, the critical exponent, Ï , is determined from the cluster distributions. Deviation from the scaling law is evaluated using a modified scaling law that includes a surface term. It is found that the surface term is unnecessary in the …

Effect of cross-linking on the diffusion of water, ions and small molecules in hydrogels
… Comparison of simulation results and obstruction scaling theory for hydrogels showed similar trends.

Microfluidic processes to create structured microparticle arrangements and their applications
… large-scale microparticle arrays using a scaling theory, which is a function of particles' characteristics. Lastly, we demonstrate the potential of generated particle arrays in various bioengineering application and material sciences. First, we synthesize anisotropic, cell-adhesive …

Hot electron injection effect and improved linearity in type-I/II DHBT for millimeter-wave mixed signal circuit applications
… and an introduction to other relevant work. Scaling theory, structure design and previous work done at the University of Illinois at Urbana-Champaign are presented in Chapter 2. Chapter 3 presents the submicron HBT process flows and processing challenges related to yield. The large area …

Energy consumption in networks on chip : efficiency and scaling
… to optimize energy consumption and model its scaling behavior as the number of cores increases. We use synthetic traffic patterns and full system simulations to test and validate our methods. Finally, we take a step back and look at the evolution of computer hardware in the last 40 years and, …

Scaling in the immune system
… how they depend on species body size. Metabolic scaling theory predicts that intracellular processes are slower in larger animals since cellular metabolic rates are slower. We test how rates of pathogenesis and immune system response rates depend on species body size. We hypothesize that immune …

Avalanches in plastic deformation: maximum velocity statistics, finite temperature effects, and analysis of low time resolution data
… whose sizes are power-law-distributed over a scaling regime. In this thesis, we study the statistics of a simple mean-field avalanche model, with emphasis on both theoretical calculations and application to the analysis of experimental data on material deformation. We establish a relationship …

Computational Study of Colloids in Suspension: Effective Interactions and Phase Transitions
… probed directly. We have developed a finite-size scaling theory that relates these density fluctuations to those of the grand-canonical ensemble, thereby enabling accurate location of critical points and coexistence curves of multi-component fluids. Several illustrative examples are presented. The …

Development of a Multiscale Atomistic Code to Investigate Self-Organized Pattern Formation Induced by Ion Irradiation
… has been mainly relied on the Bradley-Harper theory that attributes the formation of self-organized patterns to the interplay between roughening by curvature dependence of erosion and smoothening by surface diffusion. Recently, the development of the crater function theory has overturned this …

The Nature of Asymmetry in Fluid Criticality
… The conventional mixing of physical variables in scaling theory introduces an asymmetric term in diameters of coexistence curves that asymptotically varies as |ΔT|1-α, where ΔT=(T-Tc)/Tc is the relative distance of the temperature T from the critical temperature Tc. "Complete …

Proximity effects and vortex dynamics in mesoscopic superconductor-normal metal-superconductor arrays
"Anderson's scaling theory of localization has proven invaluable in characterizing the behavior of real systems, that is, those possessing any amount of disorder. The theory predicts that, at zero temperature in 1D and 2D systems, the diffusive motion of electrons scattering off impurities ceases, …
