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.
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, …
The Effect Of Alternative Fuels And Aftertreatment Devices On Measured Mobile School Bus Emissions, Andrew Todd Toback
The Effect Of Alternative Fuels And Aftertreatment Devices On Measured Mobile School Bus Emissions, Andrew Todd Toback
Theses and Dissertations
Since January 2002, the New Jersey Department of Transportation (NJDOT) has sponsored a research study at Rowan University to develop strategies for reducing diesel emissions from mobile sources such as school buses and class 8 trucks. This thesis presents research conducted on reducing emissions from school buses during mobile operating conditions. Four fuel blends and three aftertreatment devices were tested on three school bus engines.
For all of the tests, exhaust gas emission measurements were made using a Sensors Semtech-D to measure CO, CO2, NO2, NO, O2, and HC, along with a Sensors PM-300 …
Selective Extraction Of Colorful Proteins Using Reverse Micelles, Loren E. Connell
Selective Extraction Of Colorful Proteins Using Reverse Micelles, Loren E. Connell
Theses and Dissertations
Biotechnology is an ever expanding field of science. As the field has expanded, research into bioseparation processes has also expanded. The need for more cost effective ways to deliver products that are in high demand is greater now than ever. Bioseparation processes are a very costly part of the overall process of product development. While traditional separation process are effective, there is promise in many new techniques being developed which have the potential to lower the costs of bioseparations.
The continuous separation method of liquid-liquid extraction using reverse micelles is one such technique. While this technique has been researched in …
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 …
