Automated Transforms Of Software Models: A Design Pattern Approach, Brandon Adam Gump

Browse all Theses and Dissertations

In the realm of software development, projects are plagued by continuous maintenance at the source code level as well as tedious transformations from formal specifications to source code. Such work consumes a large amount of time only to create complicated, un-intelligible, and un-reusable code that is completely detached from initial design rational. To cope with these problems, The Air Force Institute of Technology (AFIT) Wide Spectrum Object Modeling Environment (AWSOME) was designed to generate specifications that can be transformed into abstract designs and finally into source code. The specifications are written in the AFIT Wide-spectrum Language (AWL) and parsed in …

A Software Framework For The Design, Testing And Deployment Of Control Systems For Autonomous Robotics, Duane Stanley Bolick Jr.

Browse all Theses and Dissertations

Simulation and control of robotic agents are common enough tasks among computer science and engineering researchers that there exists a large variety of software applications, toolkits, and programming frameworks designed to facilitate such research. The intent of this project is to provide an autonomous robotics simulation and control framework with sufficiently useful tools and reference implementations so as to be immediately useful to basic users, as well as easily understood and extended by software developers and robotics researchers.

As such, this document describes the implementation of a general networking toolkit, an autonomous robotics extension framework, and an autonomous robotics simulator …

A System For Incorporating Time-Based Event-Condition-Action Rules Into Business Databases, Christina Marie Steidle

Browse all Theses and Dissertations

Human beings handle time-based events continuously; however the passage of time does not play an active part in most business systems because they are typically driven by interaction from human users or other systems. In order to take an action based upon the passage of time it is necessary to build a framework which will monitor the progression of time and a way to define what events the system should be waiting for. This thesis describes such a system, and shows that the system performs as specified. With this system business users are able to build event-condition-action rules using a …

Computational Analysis Of Metabolomic Toxicological Data Derived From Nmr Spectroscopy, Benjamin J. Kelly

Browse all Theses and Dissertations

Nuclear magnetic resonance (NMR) spectroscopy is a non-invasive method of acquiring metabolic profiles from biofluids. The most informative metabolomic features, or biomarkers, may provide keys to the early detection of changes within an organism such as those that result from exposure to a toxin. One major difficulty with typical NMR data, whether it come from a toxicological, medical or other source, is that it features a low sample size relative to the number of variables measured. Thus, traditional pattern recognition techniques are not always feasible. The "curse of dimensionality" is an important consideration in selecting appropriate statistical and pattern recognition …

Investigation And Quantification Of Codon Usage Bias Trends In Prokaryotes, Amanda L. Hanes

Browse all Theses and Dissertations

Organisms construct proteins out of individual amino acids using instructions encoded in the nucleotide sequence of a DNA molecule. The genetic code associates combinations of three nucleotides, called codons, with every amino acid. Most amino acids are associated with multiple synonymous codons, but although they result in the same amino acid and thus have no effect on the final protein, synonymous codons are not present in equal amounts in the genomes of most organisms. This phenomenon is known as codon usage bias, and the literature has shown that all organisms display a unique pattern of codon usage. Research also suggests …
