Characterization of functionally graded materials through fractal geometry
… and characteristics of the FGM in terms of fractals. There has been no prior literature on linking FGM and fractals. We characterize the interfaces between the two- phase FGM using fractals and estimate an interfacial fractal dimension for varying degrees of coarseness. Also, the variation …

A Model For The Absorption Of Thermal Radiation By Gold-Black
… absorption of thermal radiation by gold-black. Fractal geometry is created to simulate the topology of gold-black. Then electrical circuits based on the topology are identified that capture the physics of the interaction between the gold-black material and incident electro-magnetic radiation. …

The noncommutative geometry of ultrametric cantor sets
… set using the techniques of Noncommutative Geometry. In particular, a spectral triple is created that can recover much of the fractal geometry of the original Cantor set. It is shown that this spectral triple can recover the metric, the upper box dimension, and in certain cases the Hausdorff …

Inquiry of Graphene Electronic Fabrication
… to produce a graphene network in the shape of a fractal Sierpinski carpet. The fractal geometry proves that PDMS microfluidic channels produce the fine feature dimensions desired during graphene oxide deposit. Thermal reduction then reduces the graphene oxide into a purified state of graphene. …

Assessing the relationship between recurring and nonrecurring traffic congestion
This discussion develops an approach for using fractal geometry and diffusion limited aggregation to describe highway traffic flow. The formulation is platoon based and is most applicable for describing uninterrupted-flow facilities. The model explains empirical models in terms of fractal …

Does root complexity affect the response of maize (Zea mays spp. mays) to abiotic stresses?
… and valuable tool in this effort is the use of fractal geometry and high-throughput phenotyping to assign a value to the complexity of the root system. Significant genetic variation exists for root system complexity in maize, making it a possible breeding target. Prior to the initiation of this …

Dynamics, Thermodynamic formalism and Perturbations of Transcendental Entire Functions of Finite Singular Type
In this dissertation, we study the dynamics, fractal geometry and the topology of the Julia set of functions in the family H which is a set in the class S, the Speiser class of entire transcendental functions which have only finitely many singular values. One can think of a function from H as a …
