Fractal analysis of topography and reflectance surfaces
The definition of a fractal has been successfully deduced from constructing the Koch curve and the Cantor set. Principles of seven methods (the ruler, box-counting, spectral structure function, intersection methods, cube-counting, and triangular prism methods) for determining the fractal dimensions …

A fractal analysis of premixed turbulent flames
In this experimental study, the fractal behavior of lean premixed wrinkled turbulent flames was investigated over a range of turbulence conditions. For this purpose a turbulent combustion rig was designed and built in which the turbulence intensity and scale could be independently varied by means …

A Fractal Analysis of the Detection of Glucose Molecules on Biosensor Surfaces
A fractal analysis for the binding and dissociation of glucose molecules to different biosensor surfaces is presented. The sensors contain immobilized glucose oxidase enzymes that have an affinity for the glucose molecules in solution. Data for different modified biosensors is modeled and analyzed, …

Fractal analysis of topography and structure across the Appalachian foreland of West Virginia
Fractal analysis was conducted on topographic relief and seismic reflection travel time data in the state of West Virginia to determine the potential influence of subsurface structure on surface topography. Seismic travel-times digitized from two east-west seismic profiles and topographic relief …

Multi Scale Contact Mechanics of Bio-Mechanical Systems with inclusion of roughness effect- Fractal Analysis
Contact mechanics of rough surfaces and surface wear will be considered. Two types of failures are considered. The first involving rapidly growing failure and the second fatigue type surface failure as a result of repetitive application of load cycle. The first type of failure will be identified …

Characterization and mitigation of crud at pressurized water reactor conditions
… of crud, this study is the first to apply fractal analysis to characterize crud. To achieve both of these goals, the IHTFP was built to obtain crud grown under the PWR thermal-hydraulic and chemical conditions. The crud-resistant coatings experiments show significantly reduced crud surface …

Multifractal analysis of memory usage patterns
The discovery of fractal phenomenon in computer-related areas such as network traffic flow leads to the hypothesis that many computer resources display fractal characteristics. The goal of this study is to apply fractal analysis to computer memory usage patterns. We devise methods for calculating …

The morphological, flow and failure characteristics of fractionated natural bulk material. Evaluation of flowability of fractionated powdered liquorice using a specially designed flowmeter. The particle morphology was assessed by computer image analysis and the failure properties by shear cell testing.
… surface texture of the particles was measured by fractal analysis. The influence of particle shape and size on the mean flow rate, coefficient of flow variation and flow uniformity were measured using a specially designed inclined tube flowmeter. The failure properties of powdered liquorice when …

The structure and stability of expanding and converging near-stoichiometric flames
… range of unstable wavelengths. This cascade is fractal in nature and a fractal analysis is pursued that results in an expression for the turbulent flame speed. Results are shown to be in good agreement with experiments. The converging flame is shown to be unconditionally unstable to disturbances …

Fuzzy modelling of the Johannesburg Security Exchange overall index
This thesis focuses on the empirical analysis of the fuzzy feature of the Johannesburg Stock Exchange Overall Index using fuzzy logic techniques. The data for the periods 1985 - 2001 is used in the analysis. Description of the fuzzy feature is crucial to the proper understanding of the movement of …
