Analysis And Transformation Of Post-Conditions, Abhinav Vasikarla Jan 2008

Analysis And Transformation Of Post-Conditions, Abhinav Vasikarla

Browse all Theses and Dissertations

Software engineers have been trying for years to develop a software synthesis system that can transform a formal specification model to a design model from which executable code can be generated. AFIT wide spectrum object modeling environment (AWESOME) is one result of their research. AWESOME presents a formal model as an abstract syntax tree. This model consists mainly of object class specifications. The methods in these classes are specified using pre and post-conditions. The intent of this thesis is to support the transformation of post-conditions to code statements. A post-condition is first categorized as dependent or independent relative to other …


Object Similarity Through Correlated Third-Party Objects, Ting Sa Jan 2008

Object Similarity Through Correlated Third-Party Objects, Ting Sa

Browse all Theses and Dissertations

Given a pair of objects, it is of interest to know how they are related to each other and the strength of their similarity. Many previous studies focused on two types of similarity measures: The first type is based on closeness of attribute values of two given objects, and the second type is based on how often the two objects co-occur in transactions/tuples.

In this thesis we study a new behavior-based similarity measure, which evaluates similarity between two objects by considering how similar their correlated third-party object sets are. Behavior-based similarity can help us find pairs of objects that have …


Performance And Complexity Co-Evaluations Of Mpeg4-Als Compression Standard For Low-Latency Music Compression, Isaac Kevin Matthew Jan 2008

Performance And Complexity Co-Evaluations Of Mpeg4-Als Compression Standard For Low-Latency Music Compression, Isaac Kevin Matthew

Browse all Theses and Dissertations

In this thesis compression ratio and latency of different classical audio music tracks are analyzed with various encoder options of MPEG4ALS. Different tracks of audio music tracks are tested with MPEG4-ALS coder with different options to find the optimum values for various parameters to obtain maximum compression ratio with minimum CPU time (encoder and decoder time). Optimum frame length for which the compression ratio saturates for music audio is found out by analyzing the results when different classical music tracks are experimented with various frame lengths. Also music tracks with varying sampling rate are tested and the compression ratio and …
