Dealing with unexpected dynamic loads in Jet and Turbine engines have always been a matter of concern and an active area of research. This thesis is an initial attempt to apply Evolvable Hardware methods for augmenting classical control methods in a generic turbine engine model. In this work, the Air Force Research Laboratory Generic Turbine Engine Model was converted into C and interfaced with a simulation of a EH VLSI control chip currently under development. The simulated EH device was allowed to evolve to augment the simulated engine's standard FADEC controller so that the whole system could tolerate unexpected, large …

This thesis presents a software system for the analysis of microarray data. Microarrays are a relatively new technology that can be used to examine the state of the genome of an organism at some instant in time. The challenge is the amount of natural variation in biological systems limits our ability to identify specific genes that may be sensitive to changes in an organism's physiology or its environment. The analysis software consists of three modules. The first module filters microarray data to reduce the complexity of the problem. The second module selects subsets of genes for evaluation using a genetic …

The growing News document archive emphasizes the need for efficient techniques to retrieve and visualize its content. We present a timeline based graphical interface for this purpose. The timeline is a graph of number of documents supporting association between entity (event, country, person, etc) etc and event (entity, country, person, etc) with respect to dates. The query is formulated based on entity, event, country, and person metadata extracted from the text of the News documents by analyzing the documents using proprietary name-entity recognizers. The timeline also provides a means to index and access relevant documents. Associations inferred on the basis …

For years software engineering researchers have been trying to come up with a software synthesis system that can transform a formal specification model into a design model from which executable code can be generated. AFIT Wide Spectrum Object Modeling Environment (AWSOME) is one such formal based software synthesis system. In this system formal specifications written in AWL are parsed into an AST (Abstract Syntax Tree). The intent of this thesis is to demonstrate the transformation of the postconditions of a method into target language statements. The methods in the classes are specified using pre-conditions and post-conditions. Transforms are developed to …
Analysis Of Very Large Scale Image Data Using Out-Of-Core Technique And Automated 3d Reconstruction Using Calibrated Images, Chandrashekara Hassan Raju

Analysis of large scale volumetric data sets is very important from the researcher's and technological point of view as it helps in understanding and analyzing the original data. For example, when analyzing volumetric images from cast arteries of pigs, it is essential to apply a suitable segmentation in order to retrieve morphometric data from the scanned image. Due to improved scanning technology, such as MicroCT, these scanned images can get as large as several gigabytes in size. In order to analyze such large scale data sets on common desktop computers is a challenge due to limited main memory. By using …

Due to their complexity, medical data sets can easily comprise of several gigabytes in size. For example, geometric representations of a coronary arterial tree spanning vessels from the large proximal coronary arteries down to the capillary level consist of 6 gigabytes or more of geometry data, depending on the accuracy of the geometric representation. Visualization of such large data sets using the CPU alone can be inefficient and time consuming since they require special out-of-core techniques due to the size of the data set. The usage of the GPU can help render such data sets faster compared to CPU-based implementations …
