Interactive Visualization Of Information Hierarchies And Applications On The Web, Confesor Santiago Iii
Interactive Visualization Of Information Hierarchies And Applications On The Web, Confesor Santiago Iii
Theses and Dissertations
The visualization of information hierarchies is concerned with the presentation of abstract hierarchical information about relationships between various entities. It has many applications in diverse domains such as software engineering, information systems, biology, and chemistry. Information hierarchies are typically modeled by an abstract tree, where vertices are entities and edges represent relationships between entities. The aim of visualizing tree drawings is to automatically produce drawings of trees which clearly reflect the relationships of the information hierarchy.
This thesis is primarily concerned with problems related to the automatic generation of area-efficient grid drawings of trees, interactively visualizing information hierarchies, and applying …

Optimization Of Optical Computed Tomography Techniques For The Synthesis Of Particle Aggregate Models, Patrick Anthony Giordano Jr.
Theses and Dissertations
The characterization of 3-D shapes of particles in geomaterial aggregate mixtures is important for understanding the micro-mechanics of granular materials. Also, numerical synthesis of 3-D particle shapes from their corresponding shape descriptors is required for developing discrete element models (DEMs) that can be used to predict particle contact-forces, and ultimately the shear strength of the aggregate mixture.
Previous work has shown that Fourier-based 3-D shape descriptors can be constructed for aggregate mixtures, using a statistical combination of 2-D projections. Furthermore, optical tomography methods using the Algebraic Reconstruction Technique (ART) algorithm has proved capable of synthesizing 3-D shapes from 2-D projections, …
Stacked Generalization For Early Diagnosis Of Alzheimer's Disease, Hardik P. Gandhi
Stacked Generalization For Early Diagnosis Of Alzheimer's Disease, Hardik P. Gandhi
Theses and Dissertations
Alzheimer's disease (AD) is a neurological disorder characterized by nerve degeneration and neuronal death. The diagnosis of AD at an early stage is a major concern due to growing number of elderly people affected by the disease, as well as the lack of a standard diagnosis procedure available to community clinics. A biomarker that will allow early diagnosis of the disease would be beneficial. Such biomarker should be noninvasive, simple to obtain, safe, inexpensive, accurate, and most importantly, must be made available to local health clinics for maximum effectiveness.
Recent studies have used wavelets and other signal processing methods to …
