Image Compression By Wavelet Transform., Panrong Xiao
Image Compression By Wavelet Transform., Panrong Xiao
Electronic Theses and Dissertations
Digital images are widely used in computer applications. Uncompressed digital images require considerable storage capacity and transmission bandwidth. Efficient image compression solutions are becoming more critical with the recent growth of data intensive, multimedia-based web applications.
This thesis studies image compression with wavelet transforms. As a necessary background, the basic concepts of graphical image storage and currently used compression algorithms are discussed. The mathematical properties of several types of wavelets, including Haar, Daubechies, and biorthogonal spline wavelets are covered and the Enbedded Zerotree Wavelet (EZW) coding algorithm is introduced. The last part of the thesis analyzes the compression results to …
Using Software Engineering Metrics In Ap Modularization., Kwaku Owusu-Tieku
Using Software Engineering Metrics In Ap Modularization., Kwaku Owusu-Tieku
Electronic Theses and Dissertations
Significant amount of work has been done in software engineering in terms of reuse. With the use of object-orientation and design patterns that support the development of reusable modules, it appears that the development and reuse of software modules in creating new systems is becoming more and more common. The software engineering world, however has taken reuse more seriously than database; more research and improvement in reuse has been made in software engineering than in database. This paper investigates how software engineering metrics can be applied in the development of reusable database modules. This research provides a model for predicting …
Quantitative Analysis Of Domain Testing Effectiveness., Narendra Koneru
Quantitative Analysis Of Domain Testing Effectiveness., Narendra Koneru
Electronic Theses and Dissertations
The criticality of the applications modeled by the real-time software places stringent requirements on software quality before deploying into real use. Though automated test tools can be used to run a large number of tests efficiently, the functionality of any test tool is not complege without providing a means for analyzing the test results to determine potential problem sub-domains and sub-domains that need to be covered, and estimating the reliability of the modeled system.
This thesis outlines a solution strategy and implementation of that strategy for deriving quantitative metrics from domain testing of real-time control software tested via simulation. The …
Leveraging Test Measurements Into Proposing Additional Domain Tests., Radhika Turlapati
Leveraging Test Measurements Into Proposing Additional Domain Tests., Radhika Turlapati
Electronic Theses and Dissertations
Accuracy and efficiency are extremely critical factors for large real-time control applications. A small oversight can cause catastrophic failure of a real-time system. Thus, these applications have to be tested meticulously to prevent any catastrophe that might occur. But, testing these applications exhaustively is not tractable, mainly due to the inherent complexity of the applications and also the huge amount of inputs and outputs that these applications involve. In order to save valuable amounts of time and resources, automated testing is imperative. Also, quantitative metrics have to be provided that assess the existing quality of the system and help increase …
Distribution List Maker Program With Inter-User Capabilities Between Universities And Colleges In The Tennessee Board Of Regents School System., Allan Richard Anderson
Distribution List Maker Program With Inter-User Capabilities Between Universities And Colleges In The Tennessee Board Of Regents School System., Allan Richard Anderson
Electronic Theses and Dissertations
E-mail is an important tool for faculty and staff at the university, college, department, and instructor levels. E-mail is a useful medium in the academic setting for corresponding at all levels. Instructors e-mail students about assignments, lectures, and urgent information: for example, postponed classes and changes in the schedule. In addition e-mail is used to let potential students know about job opportunities. Other routine uses for e-mail include group communications within academic committees and groups of students collaborating on projects.
Most users of e-mail who send messages to multiple recipients enter each recipients e-mail address into the TO: field individually …
A Data Layout Descriptor Language (Ladel)., Ashfaq Ahmed Jeelani
A Data Layout Descriptor Language (Ladel)., Ashfaq Ahmed Jeelani
Electronic Theses and Dissertations
To transfer data between devices and main memory, standard C block I/O interfaces use block buffers of type char. C++ programs that perform block I/O commonly use typecasting to move data between structures and block buffers. The subject of this thesis, the layout description language (LADEL), represents a high-level solution to the problem of block buffer management. LADEL provides operators that hide the casting ordinarily required to pack and to unpack buffers and guard against overflow of the virtual fields. LADEL also allows a programmer to dynamically define a structured view of a block buffer's contents. This view includes the …
Integration Of Student Academic Record And Major Requirements Through Xml., Zhujun Hou
Integration Of Student Academic Record And Major Requirements Through Xml., Zhujun Hou
Electronic Theses and Dissertations
The purpose of this thesis is to develop a software application based on previous studies by 1997 Oak Ridge Design Studio Team that matches students' progress with major requirements in their college career. This study addresses the problems of previous studies and suggests a solution. A powerful new technique, XML, is used to model, store and process the data of major requirements and student records. This application produces an HTML file that provides detailed information of a student's academic progress towards graduation.
